本发明涉及车辆技术领域，特别涉及一种车辆的启动控制方法、装置和车辆。The present invention relates to the technical field of vehicles, in particular to a vehicle startup control method, device and vehicle.
背景技术Background technique
在新能源车领域，锂电池在众多车型中得到广泛应用。就使用功能而言，锂电池在整车领域主要有三种用途：一是作为电动汽车的动力电池，为整车提供动力来源，包括目前较为主流的EV(纯电动)电动车和PHEV(插电式混合动力)电动车；二是作为启动电池，替换目前铅酸电池的功能；三是作为辅助能源，即就是我们常说绿混，电池模组除了承担铅酸电池的用途外，还需要承担刹车能量回馈、动力助力辅助等功能。当然，在部分车型中，也有将锂电池主要作为混合动力辅助能源使用，锂电池不取代铅酸电池，而只用于承担刹车能量回馈、动力助力等功能。无论锂电池在整车领域扮演什么样的角色，由于锂电池材料的固有特性的原因，它对使用环境的要求比较苛刻。在当前技术条件下，锂电池很难做到兼顾高低温下正常大电流充放电性能，实际上锂电池在低温条件下，尤其是低于-20℃，锂电池的大倍率放电性能劣化至不足常温水平的30％，而在更低的温度下，其大倍率放电性能甚至不到常温水平的5％。In the field of new energy vehicles, lithium batteries are widely used in many models. In terms of use function, lithium batteries have three main uses in the field of complete vehicles: one is as a power battery for electric vehicles to provide power sources for complete vehicles, including the current mainstream EV (pure electric) electric vehicles and PHEV (plug-in electric vehicles) Type hybrid) electric vehicles; second, as a starter battery, replacing the current function of lead-acid batteries; third, as an auxiliary energy source, that is, we often say that green hybrids, battery modules not only assume the use of lead-acid batteries, but also need to undertake Braking energy feedback, power assist and other functions. Of course, in some models, lithium batteries are mainly used as auxiliary energy for hybrid power. Lithium batteries do not replace lead-acid batteries, but are only used for braking energy feedback, power assist and other functions. No matter what role lithium batteries play in the vehicle field, due to the inherent characteristics of lithium battery materials, it has strict requirements on the use environment. Under the current technical conditions, it is difficult for lithium batteries to take into account the normal high-current charge and discharge performance at high and low temperatures. In fact, under low temperature conditions, especially below -20°C, the high-rate discharge performance of lithium batteries deteriorates to insufficient 30% of the normal temperature level, and at lower temperatures, its high-rate discharge performance is even less than 5% of the normal temperature level.
在传统燃油车领域，整车在低温下也经常出现无法打火的现象，尤其是使用过一段时间的“旧车”。究其原因，铅酸电池使用一段时间后容量和放电能力快速下降，导致其输入给启动电机的持续电流值降低，无法提供给发动机较高的扭矩所致。众所周知，铅酸电池经过一段时候的高温后容量下降很快，大电流放电能力更差，远远低于锂离子电池的容量保持率和储存性能。锂电池替代传统的铅酸电池，更有助于实现整车的无铅化，同时较铅酸电池有更为良好的循环性能和使用寿命。正如前面所说，目前锂电池仍然存在一个弱点，那就是低温大电流放电能力不足的问题，这个对于整车的打火能力来说存在挑战。In the field of traditional fuel vehicles, the vehicle often fails to ignite at low temperatures, especially "old vehicles" that have been used for a period of time. The reason is that the capacity and discharge capacity of the lead-acid battery decrease rapidly after being used for a period of time, resulting in a decrease in the continuous current value input to the starter motor, which cannot provide high torque to the engine. As we all know, the capacity of lead-acid batteries decreases rapidly after a period of high temperature, and the high-current discharge capacity is even worse, which is far lower than the capacity retention and storage performance of lithium-ion batteries. Lithium batteries replace traditional lead-acid batteries, which is more conducive to the realization of lead-free vehicles, and has better cycle performance and service life than lead-acid batteries. As mentioned above, there is still a weakness in lithium batteries at present, that is, the insufficient low-temperature and high-current discharge capacity, which poses a challenge to the ignition capacity of the whole vehicle.
在相关技术中，整车打火程序一般是先切断启动电池和低压端用电器的连接，通过启动电池给启动电机通电，启动电机产生扭矩作用于发动机，发动机达到一定转速后整车才能正常启动。传统燃油车为了提高铅酸电池在低温下的打火性能，一般都配置较高容量的铅酸电池或两个铅酸电池，大大增加了投入成本，同时铅酸电池的循环寿命下降很快，很快会再遇到低温下打火问题；还有一些本领域技术人员将电池表面紧贴热敏电阻片，低温下通过外加电源给热敏电阻片放电以达到给启动电池加热的目的，这种设计在实施过程中很难实现，在增加了安装空间的同时又加大了成本的投入，得不偿失。In the related technology, the ignition procedure of the whole vehicle is generally to cut off the connection between the starting battery and the low-voltage side electrical appliances first, then energize the starting motor through the starting battery, and the starting motor generates torque to act on the engine, and the whole vehicle can start normally only after the engine reaches a certain speed . In order to improve the ignition performance of lead-acid batteries at low temperatures, traditional fuel vehicles are generally equipped with higher-capacity lead-acid batteries or two lead-acid batteries, which greatly increases the input cost, and the cycle life of lead-acid batteries decreases rapidly. It will soon encounter the problem of sparking at low temperature again; there are also some technicians in the field who put the surface of the battery close to the thermistor sheet, and discharge the thermistor sheet through an external power supply at low temperature to achieve the purpose of heating the starting battery. This kind of design is difficult to realize in the implementation process, while increasing the installation space and increasing the cost input, the gain outweighs the gain.

The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
图1是根据本发明一个实施例的车辆的启动控制方法的流程图。如图1所示，本发明实施例的车辆的启动控制方法包括下述步骤。FIG. 1 is a flow chart of a vehicle startup control method according to an embodiment of the present invention. As shown in FIG. 1 , the start control method of the vehicle according to the embodiment of the present invention includes the following steps.
S101，实时获取启动电源的温度。S101, acquiring the temperature of the starting power supply in real time.
在本发明的一个实施例中，启动电源为锂离子二次电池。In one embodiment of the present invention, the starting power supply is a lithium-ion secondary battery.
具体地，启动电源具有电池管理器(即BMS，Battery Management System，电池管理系统)，电池管理器通过温度传感器以及温度采集线束实时采集启动电源的温度。其中，电池管理器与车辆中的CAN(Controller Area Network，控制器局域网络)总线相连，电池管理器采集到启动电源的温度后，将启动电源的温度发送到车辆的CAN网络上。Specifically, the starting power supply has a battery manager (ie, BMS, Battery Management System, battery management system), and the battery manager collects the temperature of the starting power supply in real time through a temperature sensor and a temperature collection harness. Wherein, the battery manager is connected to the CAN (Controller Area Network) bus in the vehicle, and after collecting the temperature of the starting power supply, the battery manager sends the temperature of the starting power supply to the CAN network of the vehicle.
此外，电池管理器还可以通过CAN总线与车辆中的ECM(Engine Control Module，引擎控制模块)、DC-DC、可发电或放电设备的电池管理器BMS等部件进行信息交互，实现低压端电量控制和优化，达到节能省油的效果。In addition, the battery manager can also exchange information with the ECM (Engine Control Module, engine control module), DC-DC, battery manager BMS and other components in the vehicle through the CAN bus to realize low-voltage end power control and optimization to achieve the effect of energy saving and fuel saving.
S102，当接收到车辆的启动信号时，判断启动电源的温度是否小于预设温度。S102. When receiving a starting signal of the vehicle, determine whether the temperature of the starting power supply is lower than a preset temperature.
在本发明的一个实施例中，预设温度为-20℃～-35℃。In one embodiment of the present invention, the preset temperature is -20°C to -35°C.
具体地，一旦电池管理器接收到外界输入的启动信号(即打火信号)，电池管理器判断启动电源的温度是否小于预设温度。例如，判断启动电源的温度是否小于-25℃。Specifically, once the battery manager receives a starting signal (ie, ignition signal) input from the outside, the battery manager judges whether the temperature of the starting power source is lower than a preset temperature. For example, it is judged whether the temperature of the starting power supply is lower than -25°C.
S103，当启动电源的温度小于预设温度时，生成第一控制信号，并将第一控制信号发送至第一继电器和第二继电器，以使第一继电器根据第一控制信号控制启动电源连接到车辆的启动电机的同时，第二继电器根据第一控制信号控制启动电机和发动机断开，并在预设时间内保持断开。S103, when the temperature of the starting power supply is lower than the preset temperature, generate a first control signal, and send the first control signal to the first relay and the second relay, so that the first relay controls the starting power supply to be connected to the first relay according to the first control signal. While starting the motor of the vehicle, the second relay controls the starting motor and the engine to be disconnected according to the first control signal, and keeps disconnected within a preset time.
在本发明的一个实施例中，预设时间为5～30秒。In one embodiment of the present invention, the preset time is 5-30 seconds.
具体地，当启动电源的温度小于预设温度时，电池管理器生成第一控制信号，并将第一控制信号发送至第一继电器和第二继电器，以使第一继电器控制启动电源连接到车辆的启动电机的同时，第二继电器控制启动电机和发动机断开，并在预设时间内保持断开。Specifically, when the temperature of the starting power supply is lower than the preset temperature, the battery manager generates a first control signal and sends the first control signal to the first relay and the second relay, so that the first relay controls the starting power supply to be connected to the vehicle At the same time as the starter motor, the second relay controls the disconnection of the starter motor and the engine, and keeps disconnection within a preset time.
在相关技术中，车辆的启动过程一般是先切断启动电源和低压端用电器的连接，通过启动电源给启动电机通电，启动电机产生扭矩作用于发动机，发动机达到一定转速整车才能正常启动。而在本发明的实施例中，当接收到外界输入的启动信号且启动电源的温度小于预设温度时(即启动电源的温度过低，不利于车辆的启动)，控制启动电源与启动电机连接的同时，控制启动电机和发动机断开，并在预设时间内保持断开，即在启动电源的温度较低时，使启动电源和启动电机进行短时间(即预设时间，例如，10秒)的短路，来提高启动电源自身的温度以及启动电机的温度。其中，车辆的系统示意图如图2所示。此处，车辆的系统示意图只是用来举例，在此，不对车辆的车型进行限制。In the related art, the starting process of the vehicle is generally to cut off the connection of the starting power supply and the low-voltage end electrical appliances first, and then energize the starter motor through the starting power supply. And in the embodiment of the present invention, when receiving the starting signal of external input and the temperature of starting power supply is less than preset temperature (that is, the temperature of starting power supply is too low, is unfavorable for the starting of vehicle), control starting power supply and starter motor connection At the same time, the starter motor and the engine are controlled to be disconnected and kept disconnected within the preset time, that is, when the temperature of the starter power supply is low, the starter power supply and the starter motor are operated for a short time (that is, the preset time, for example, 10 seconds) ) to increase the temperature of the starting power supply itself and the temperature of the starting motor. Among them, the schematic diagram of the vehicle system is shown in Fig. 2 . Here, the schematic diagram of the system of the vehicle is only used as an example, and the model of the vehicle is not limited here.
S104，经过预设时间之后，生成第二控制信号，并将第二控制信号发送至第二继电器，以使第二继电器根据第二控制信号控制启动电机和发动机连接，以启动车辆。S104, after the preset time elapses, generate a second control signal and send the second control signal to the second relay, so that the second relay controls the connection between the starter motor and the engine according to the second control signal to start the vehicle.
具体地，经过预设时间之后，启动电源的温度和启动电机的温度都有所提升，那么，电池管理器生成第二控制信号，并将第二控制信号发送至第二继电器，以使第二继电器控制启动电机和发动机连接，这时开始执行打火程序，就可以正常启动车辆。Specifically, after the preset time has elapsed, the temperature of the starting power supply and the temperature of the starting motor both increase, then the battery manager generates a second control signal and sends the second control signal to the second relay, so that the second The relay controls the connection between the starter motor and the engine. At this time, the ignition procedure is started, and the vehicle can be started normally.
本发明实施例的车辆的启动控制方法，实时获取启动电源的温度，当接收到车辆的启动信号时，如果启动电源的温度小于预设温度，则控制启动电源连接到启动电机的同时，断开启动电机和发动机的连接，以使启动电源和启动电机在预设时间内短路，以提高启动电源和启动电机的温度，经过预设时间之后，控制启动电机连接至发动机，以正常启动车辆，该方法可以提升车辆在低温下的打火能力，拓宽了车辆的使用温度区间和使用区域，提升了用户体验，从而提升了车辆的竞争力。The starting control method of the vehicle in the embodiment of the present invention acquires the temperature of the starting power supply in real time, and when the starting signal of the vehicle is received, if the temperature of the starting power supply is lower than the preset temperature, then the starting power supply is controlled to be connected to the starting motor and disconnected at the same time. The connection of the starter motor and the engine, so that the starter power supply and the starter motor are short-circuited within a preset time to increase the temperature of the starter power supply and the starter motor, and after the preset time passes, the starter motor is controlled to be connected to the engine to start the vehicle normally, the The method can improve the ignition capability of the vehicle at low temperature, widen the temperature range and area of use of the vehicle, improve user experience, and thereby enhance the competitiveness of the vehicle.
需要说明的是，本发明实施例的车辆的启动控制方法，可以应用到多种车型中，例如，普通燃油车型(发电机不带LIN总线)、普通燃油车型(发电机带有LIN总线)、混合动力车型(发电机不带LIN总线)和混合动力车型(发电机带有LIN总线)。其中，上述车型的系统示意图分别如图3A、图3B、图3C和图3D所示。其中，LIN(Local Interconnect Network，局域互连网络)总线是一种低成本的串行通讯网络。It should be noted that the starting control method of the vehicle in the embodiment of the present invention can be applied to various vehicle types, for example, ordinary fuel vehicle models (generator without LIN bus), ordinary fuel vehicle vehicles (generator with LIN bus), Hybrid models (generator without LIN bus) and hybrid models (generator with LIN bus). Wherein, the schematic diagrams of the systems of the above vehicle types are shown in FIG. 3A , FIG. 3B , FIG. 3C and FIG. 3D respectively. Among them, the LIN (Local Interconnect Network, Local Interconnect Network) bus is a low-cost serial communication network.
下面对启动电源(即锂离子二次电池)和其电池管理器的功能进行简单介绍。如图4所示为启动电源的内部原理示意图，图5所示为启动电源的外部接线图。The following briefly introduces the functions of the starting power supply (that is, the lithium-ion secondary battery) and its battery manager. Figure 4 shows the schematic diagram of the internal principle of the starting power supply, and Figure 5 shows the external wiring diagram of the starting power supply.
在本发明的实施例中，锂离子二次电池替代了传统的铅酸蓄电池，锂离子二次电池的功能如下：In an embodiment of the invention, the lithium-ion secondary battery replaces the traditional lead-acid storage battery, and the function of the lithium-ion secondary battery is as follows:
(1)对于车辆的电子控制系统来说，未进入超低功耗情况下，锂离子二次电池是电子控制装置的不间断电源。(1) For the electronic control system of the vehicle, the lithium-ion secondary battery is the uninterruptible power supply of the electronic control device when the ultra-low power consumption is not entered.
(2)启动时，锂离子二次电池向启动系统单独供电，BMS控制MOS管电路。(2) When starting, the lithium-ion secondary battery supplies power to the starting system alone, and the BMS controls the MOS tube circuit.
(3)当发电机和DC-DC降压输出不足时，由锂离子二次电池辅助向用电设备供电。(3) When the generator and DC-DC step-down output are insufficient, the lithium-ion secondary battery assists in supplying power to electrical equipment.
(4)锂离子二次电池还可以吸收电路中的瞬时过电压，保持车辆的电器系统电压的稳定，保护电子元件。(4) The lithium-ion secondary battery can also absorb the instantaneous overvoltage in the circuit, maintain the stability of the electrical system voltage of the vehicle, and protect the electronic components.
(5)可以检测锂离子二次电池的SOC、电流、电压、温度，并向ECM反馈信息，判断电池SOC将起停允许/不允许通过网关发送给电喷，进行起停控制。(5) It can detect the SOC, current, voltage, and temperature of the lithium-ion secondary battery, and feed back information to the ECM to judge whether the battery SOC is allowed or not allowed to start and stop and send it to the EFI through the gateway for start and stop control.
(6)锂离子二次电池故障报警功能，当锂离子二次电池故障报警时，仪表上故障指示灯点亮(常亮)，同时显示“请检查低压电池系统”等相关字样。(6) Lithium-ion secondary battery fault alarm function. When the lithium-ion secondary battery fault alarms, the fault indicator light on the instrument will be on (steady on), and relevant words such as "Please check the low-voltage battery system" will be displayed at the same time.
(7)智能充电和超低功耗功能，在OFF、ACC、ON档电时，当锂离子二次电池的BMS监测到自身SOC过低时，控制吸合OFF档充电继电器，同时给整车可发电或放电设备BMS发送充电请求信号，整车可发电或放电设备BMS接收并检测判定后吸合放电主接触器，发送“放电允许”或“发电允许”信号给双向DC，双向DC判断自身无故障后给锂离子二次电池进行智能充电。当锂离子二次电池的BMS收到整车可发电或放电设备BMS“放电不允许”信号时，锂离子二次电池的BMS不再给整车可发电或放电设备BMS发充电请求信号，锂离子二次电池的BMS切断低压回路，即断开整车电源，进入超低功耗状态。BMS切断电源进入超低功耗状态后，只保留电池SOC检测功能和驾驶侧车门微动开关监测功能，当检测到开关信号有效后唤醒，恢复供电。(7) Intelligent charging and ultra-low power consumption functions. When the BMS of the lithium-ion secondary battery detects that its own SOC is too low when it is powered on in OFF, ACC, and ON gears, it will control the charging relay in OFF gear and charge the vehicle at the same time. The BMS that can generate electricity or discharge equipment sends a charging request signal, and the BMS that can generate electricity or discharge equipment for the whole vehicle receives and detects and judges, and then pulls in the discharge main contactor, and sends a "discharge permission" or "power generation permission" signal to the bidirectional DC, and the bidirectional DC judges itself Intelligently charge the lithium-ion secondary battery after no failure. When the BMS of the lithium-ion secondary battery receives the "discharge not allowed" signal from the BMS of the vehicle's power generation or discharge equipment, the BMS of the lithium-ion secondary battery will no longer send a charging request signal to the BMS of the vehicle's power generation or discharge equipment. The BMS of the ion secondary battery cuts off the low-voltage circuit, that is, disconnects the vehicle power supply and enters an ultra-low power consumption state. After the BMS cuts off the power supply and enters the ultra-low power consumption state, it only retains the battery SOC detection function and the micro switch monitoring function of the driver's side door. When it detects that the switch signal is valid, it wakes up and restores power supply.
此外，锂离子二次电池的BMS具有的功能如下：In addition, the BMS of lithium-ion secondary batteries has the following functions:
1)电压采样。BMS分别对组内电池进行单组电压采样；同时BMS需能对锂离子二次电池的总电压进行采样。单组电压、总电压均应能通过CAN口发到整车网络上。1) Voltage sampling. The BMS samples the voltage of a single group of batteries in the group respectively; at the same time, the BMS needs to be able to sample the total voltage of the lithium-ion secondary battery. Both the single group voltage and the total voltage should be able to be sent to the vehicle network through the CAN port.
2)温度采样。BMS分别对组内电池进行单组温度采样，要求一定的采样精度和采样范围；同时BMS需对锂离子二次电池平均温度进行采样，要求一定的采样精度和采样范围。单组温度、平均温度均应能通过CAN口发到整车CAN网络上。2) Temperature sampling.

As shown in FIG. 6 , the vehicle starting control device according to the embodiment of the present invention includes: a starting power supply 100 , a battery manager 200 , a first relay 310 , a second relay 320 , a starting motor 400 and an engine 500 . The first relay 310 is respectively connected with the starter power 100 , the battery manager 200 and the starter motor 400 , and the second relay 320 is connected with the starter power 100 , the battery manager 200 , the starter motor 400 and the engine 500 respectively.
其中，电池管理器200用于实时获取启动电源100的温度，并在接收到车辆的启动信号时，电池管理器200判断启动电源100的温度是否小于预设温度，若启动电源100的温度小于预设温度，电池管理器200生成第一控制信号，并将第一控制信号发送至第一继电器310和第二继电器320；第一继电器310用于根据第一控制信号控制启动电源100连接到启动电机400，同时，第二继电器320用于根据第一控制信号控制启动电机400和发动机500断开，并在预设时间内保持断开；电池管理器200还用于在预设时间之后生成第二控制信号，并将第二控制信号发送至第二继电器320，第二继电器320根据第二控制信号控制启动电机400和发动机500连接，以启动车辆。Wherein, the battery manager 200 is used to acquire the temperature of the starting power source 100 in real time, and when receiving the starting signal of the vehicle, the battery manager 200 judges whether the temperature of the starting power source 100 is lower than the preset temperature, if the temperature of the starting power source 100 is lower than the preset temperature Set the temperature, the battery manager 200 generates a first control signal, and sends the first control signal to the first relay 310 and the second relay 320; the first relay 310 is used to control the starter power supply 100 to connect to the starter motor according to the first control signal 400. At the same time, the second relay 320 is used to control the starter motor 400 and the engine 500 to be disconnected according to the first control signal, and to keep disconnected within a preset time; the battery manager 200 is also used to generate a second relay after the preset time. control signal, and send the second control signal to the second relay 320, and the second relay 320 controls the connection between the starter motor 400 and the engine 500 according to the second control signal, so as to start the vehicle.
其中，电池管理器200可以置于启动电源100外(如图6所示)，电池管理器200也可以内置于启动电源100中(如图7所示)。其中，第一继电器310/第二继电器320与电池管理器200之间的连线为信号控制线，第一继电器310/第二继电器320与启动电源100(即电池)之间的连线为动力线。Wherein, the battery manager 200 can be placed outside the starting power supply 100 (as shown in FIG. 6 ), or the battery manager 200 can be built in the starting power supply 100 (as shown in FIG. 7 ). Among them, the connection between the first relay 310/second relay 320 and the battery manager 200 is a signal control line, and the connection between the first relay 310/second relay 320 and the starting power supply 100 (ie, the battery) is a power Wire.
在本发明的一个实施例中，启动电源100为锂离子二次电池。In one embodiment of the present invention, the starting power supply 100 is a lithium-ion secondary battery.
具体地，电池管理器200通过温度传感器以及温度采集线束实时采集启动电源100的温度。其中，电池管理器200与车辆中的CAN总线相连，电池管理器200采集到启动电源的温度后，将启动电源100的温度发送到车辆的CAN网络上。Specifically, the battery manager 200 collects the temperature of the starting power supply 100 in real time through a temperature sensor and a temperature collection harness. Wherein, the battery manager 200 is connected to the CAN bus in the vehicle, and after collecting the temperature of the starter power, the battery manager 200 sends the temperature of the starter power 100 to the CAN network of the vehicle.
此外，电池管理器200还可以通过CAN总线与车辆中的ECM、DC-DC、可发电或放电设备的电池管理器BMS等部件进行信息交互，实现低压端电量控制和优化，达到节能省油的效果。In addition, the battery manager 200 can also exchange information with components such as the ECM, DC-DC, and the battery manager BMS of the power generation or discharge device in the vehicle through the CAN bus, so as to realize power control and optimization at the low-voltage end, and achieve energy saving and fuel saving effects. .
在本发明的一个实施例中，预设温度为-20℃～-35℃，预设时间为5～30秒。In one embodiment of the present invention, the preset temperature is -20°C to -35°C, and the preset time is 5 to 30 seconds.
更具体地，一旦电池管理器200接收到外界输入的启动信号(即打火信号)，电池管理器200判断启动电源100的温度是否小于预设温度。例如，判断启动电源100的温度是否小于-25℃。当启动电源100的温度小于预设温度时，电池管理器200生成第一控制信号，并将第一控制信号发送至第一继电器310和第二继电器320，以使第一继电器310控制启动电源100连接到车辆的启动电机400的同时，第二继电器320控制启动电机400和发动机500断开，并在预设时间内保持断开。More specifically, once the battery manager 200 receives an external start signal (ie, ignition signal), the battery manager 200 determines whether the temperature of the start-up power supply 100 is lower than a preset temperature. For example, it is judged whether the temperature of the starting power supply 100 is lower than -25°C. When the temperature of the starting power supply 100 is lower than the preset temperature, the battery manager 200 generates a first control signal, and sends the first control signal to the first relay 310 and the second relay 320, so that the first relay 310 controls the starting power supply 100 While being connected to the starter motor 400 of the vehicle, the second relay 320 controls the starter motor 400 and the engine 500 to be disconnected and kept disconnected for a preset time.
在相关技术中，车辆的启动过程一般是先切断启动电源和低压端用电器的连接，通过启动电源给启动电机通电，启动电机产生扭矩作用于发动机，发动机达到一定转速整车才能正常启动。而在本发明的实施例中，当电池管理器200接收到外界输入的启动信号且启动电源100的温度小于预设温度时(即启动电源100的温度过低，不利于车辆的启动)，电池管理器200通过第一继电器310控制启动电源100与启动电机400连接的同时，通过第二继电器320控制启动电机400和发动机500断开，并在预设时间内保持断开，即在启动电源100的温度较低时，使启动电源100和启动电机400进行短时间(即预设时间，例如，10秒)的短路，来提高启动电源100自身的温度以及启动电机400的温度。In the related art, the starting process of the vehicle is generally to cut off the connection of the starting power supply and the low-voltage end electrical appliances first, and then energize the starter motor through the starting power supply. However, in the embodiment of the present invention, when the battery manager 200 receives a starting signal input from the outside and the temperature of the starting power supply 100 is lower than the preset temperature (that is, the temperature of the starting power supply 100 is too low, which is not conducive to the starting of the vehicle), the battery The manager 200 controls the connection between the starter power supply 100 and the starter motor 400 through the first relay 310, and at the same time controls the disconnection of the starter motor 400 and the engine 500 through the second relay 320, and keeps it disconnected within a preset time, that is, when the starter power supply 100 When the temperature is low, the starting power supply 100 and the starting motor 400 are short-circuited for a short time (that is, a preset time, for example, 10 seconds) to increase the temperature of the starting power supply 100 itself and the temperature of the starting motor 400.
进一步地，经过预设时间之后，启动电源100的温度和启动电机400的温度都有所提升，那么，电池管理器200生成第二控制信号，并将第二控制信号发送至第二继电器320，以使第二继电器320控制启动电机400和发动机500连接，这时开始执行打火程序，就可以正常启动车辆。Further, after the preset time, the temperature of the starter power supply 100 and the temperature of the starter motor 400 both increase, then the battery manager 200 generates a second control signal and sends the second control signal to the second relay 320, The second relay 320 controls the connection between the starter motor 400 and the engine 500, and at this moment, the ignition procedure is started, and the vehicle can be started normally.
本发明实施例的车辆的启动控制装置，电池管理器实时获取启动电源的温度，当电池管理器接收到车辆的启动信号时，如果启动电源的温度小于预设温度，则电池管理器通过第一继电器控制启动电源连接到启动电机的同时，通过第二继电器控制断开启动电机和发动机的连接，以使启动电源和启动电机在预设时间内短路，以提高启动电源和启动电机的温度，经过预设时间之后，电池管理器通过第二继电器控制启动电机连接至发动机，以正常启动车辆，该装置可以提升车辆在低温下的打火能力，拓宽了车辆的使用温度区间和使用区域，提升了用户体验，从而提升了车辆的竞争力。In the starting control device of the vehicle according to the embodiment of the present invention, the battery manager obtains the temperature of the starting power source in real time. When the battery manager receives the starting signal of the vehicle, if the temperature of the starting power source is lower than the preset temperature, the battery manager passes the first While the relay controls the starting power supply to be connected to the starting motor, the connection between the starting motor and the engine is disconnected through the second relay control, so that the starting power supply and the starting motor are short-circuited within a preset time to increase the temperature of the starting power supply and the starting motor.
