为了提高车辆续航里程，提高能源使用效率及降低客户的运营成本，增程器在新能源汽车领域得到越来越多的应用。增程器指能够提供额外的电能，从而使电动汽车能够增加行驶里程的电动汽车零部件，传统意义上的增程器指发动机与发电机的组合。电动汽车上的增程器能够在电池电量不足的情况下使用其它能源(如汽油)进行电能补给。增程器产生的电能通过电瓶供给电机驱动，同时还可供给电池充电。In order to improve vehicle cruising range, improve energy efficiency and reduce customers' operating costs, range extenders are increasingly used in the field of new energy vehicles. A range extender refers to an electric vehicle component that can provide additional electrical energy so that an electric vehicle can increase the mileage. A range extender in the traditional sense refers to a combination of an engine and a generator. Range extenders on electric vehicles can use other energy sources, such as gasoline, to power up when the battery is running low. The electric energy generated by the range extender is supplied to the motor through the battery, and can also be used to charge the battery.
目前，甲醇增程器系统作为一种现有方案，较为广泛的应用与汽车或工业领域，由于其燃料的环保性相较于其他传统化石燃料较高，获取及运输成本相对低廉，在市场中具备较强的竞争性。At present, the methanol range extender system, as an existing solution, is widely used in the automotive or industrial fields. Compared with other traditional fossil fuels, the methanol range extender system is more environmentally friendly, and the acquisition and transportation costs are relatively low. In the market Have strong competitiveness.
当前技术中的增程器系统常常使用一台増程器进行补给供能，但是由于能源使用效率优化及驱动系统需求功率与发电功率匹配性不足等因素的影响，实际使用时，增程器系统可调节功率输出范围不足，无法满足车辆运行需求，降低了车辆的功能多样性。The range extender system in the current technology often uses a range extender to supply energy. However, due to factors such as the optimization of energy use efficiency and the lack of matching between the required power of the drive system and the generated power, the range extender system is actually used. The adjustable power output range is insufficient to meet the vehicle operation requirements, reducing the functional diversity of the vehicle.
本申请的核心是提供一种增程器系统控制方法、装置以及介质，应用于包括多个增程器的增程器系统，用于在不同的情况下投入不同数目的增程器，以提高功率输出范围，满足车辆运行需求，扩展车辆的功能多样性。The core of the present application is to provide a range extender system control method, device and medium, which are applied to a range extender system including a plurality of range extenders, and are used to invest different numbers of range extenders in different situations, so as to improve the The power output range meets the needs of vehicle operation and expands the functional diversity of the vehicle.
为了使本技术领域的人员更好地理解本申请方案，下面结合附图和具体实施方式对本申请作进一步的详细说明。In order to make those skilled in the art better understand the solution of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
图1为本申请实施例提供的一种增程器系统控制方法的流程图，该方法应用于包括多个增程器的增程器系统，如图1所示，该方法包括：1 is a flowchart of a method for controlling a range extender system provided by an embodiment of the present application. The method is applied to a range extender system including a plurality of range extenders. As shown in FIG. 1 , the method includes:
S10：获取车辆电池的SOC或车辆行驶的需求功率。S10: Acquire the SOC of the vehicle battery or the required power for driving the vehicle.
本实施例中的执行主体可以是增程器系统控制装置，也可以是新能源整车控制器(VCU)，VCU是新能源车辆控制系统中的“大脑级”控制器，负责车辆的行驶控制、附件管理、能量管理、故障处理、信息交互等功能。整车控制器根据功能将车辆分成多个控制器局域网络(Controller Area Network，CAN)，其可以将信息传输至各CAN网络中的电子控制单元(Electronic Control Unit，ECU)，实现对各CAN网络的控制，进而实现不同的功能。The executive body in this embodiment may be a range extender system control device, or a new energy vehicle controller (VCU). The VCU is a "brain-level" controller in the new energy vehicle control system, responsible for the driving control of the vehicle , accessory management, energy management, fault handling, information interaction and other functions. The vehicle controller divides the vehicle into multiple Controller Area Networks (CAN) according to the functions, which can transmit information to the Electronic Control Unit (ECU) in each CAN network to realize the control of each CAN network. control to achieve different functions.
图2为本申请实施例提供的一种CAN网络拓扑图，该CAN网络即为增程器系统的CAN网络，图2中以两台增程器组成的增程器系统为例，在增程器系统中，还包括发电机控制单元(GCU)以及用于散热的风扇，GCU作为增程器系统的核心部件用来启动发动机，将发动机能量转换为电能，给电池充电、给驱动电机提供能量，其承担着发动机启停、能量转换、提高效率、节能减排的任务。本实施例中的VCU除了通过CAN实现和ECU的通信外，还通过CAN与诊断接口连接，用于对车辆的故障进行检测。Fig. 2 is a kind of CAN network topology diagram that this application embodiment provides, this CAN network is the CAN network of the range extender system, in Fig. The generator system also includes a generator control unit (GCU) and a fan for heat dissipation. As the core component of the range extender system, the GCU is used to start the engine, convert the engine energy into electrical energy, charge the battery, and provide energy to the drive motor. , which undertakes the tasks of starting and stopping the engine, energy conversion, improving efficiency, energy saving and emission reduction. In this embodiment, in addition to communicating with the ECU through CAN, the VCU is also connected to the diagnosis interface through CAN, so as to detect the failure of the vehicle.
荷电状态(state of charge，SOC)是指蓄电池使用一段时间或长期搁置不用后的剩余容量与其完全充电状态的容量的比值，常用百分数表示。其取值范围为0～1，当SOC＝0时表示电池放电完全，当SOC＝1时表示电池完全充满。State of charge (SOC) refers to the ratio of the remaining capacity of a battery after being used for a period of time or left unused for a long time to its capacity in a fully charged state, usually expressed as a percentage. Its value ranges from 0 to 1. When SOC=0, it means that the battery is fully discharged, and when SOC=1, it means that the battery is fully charged.
在具体实施中，VCU在上电之后，从各CAN网络获取到车辆状态，包括车辆电池的SOC、车辆行驶的需求功率以及车辆的故障信息等。在本实施例中，本申请的目的是想要根据实际情况选择需要投入的增程器的个数，而SOC代表着车辆电池的荷电状态，车辆行驶的需求功率代表着车辆需求，该两项内容都能表征需要使用增程器的急切程度，因此，在步骤S10中，VCU需要收集车辆电池的SOC或者车辆行驶的需求功率。In a specific implementation, after the VCU is powered on, it obtains the vehicle status from each CAN network, including the SOC of the vehicle battery, the required power for the vehicle to travel, and the fault information of the vehicle. In this embodiment, the purpose of this application is to select the number of range extenders that need to be put in according to the actual situation, and the SOC represents the state of charge of the vehicle battery, the required power of the vehicle driving represents the vehicle demand, and the two The content of each item can represent the urgency of using the range extender. Therefore, in step S10, the VCU needs to collect the SOC of the vehicle battery or the required power of the vehicle running.
本实施例还提供一种计算需求功率的公式，如下所示：This embodiment also provides a formula for calculating the required power, as shown below:
其中，W为需求功率，VMAX为最高车速，ηt为整车动力传动系统效率，m为整车质量，g为重力加速度，f为滚动阻力系数，CD为风阻系数，A为迎风面积。需要说明的是，W是车辆行驶整体所需的需求功率，其中包括了车辆行驶所需的功率，还包括车辆的附件(例如空调)所需的功率，车辆行驶功率＝W-P消，其中，P消为附件消耗功率。Among them, W is the required power, VMAX is the maximum vehicle speed, ηt is the powertrain efficiency of the vehicle, m is the vehicle mass, g is the gravitational acceleration, f is the rolling resistance coefficient, CD is the wind resistance coefficient, and A is the windward area . It should be noted that W is the required power required for the vehicle to run as a whole, which includes the power required for the vehicle to run, and also includes the power required by the vehicle's accessories (such as air conditioners). Vehicle running power = WPconsumption , where P toconsume power for accessories.
S11：确定SOC或需求功率与各自对应的预设阈值的偏差程度。S11: Determine the degree of deviation between the SOC or the demanded power and the respective corresponding preset thresholds.
S12：根据偏差程度确定投入增程器的个数；偏差程度与增程器的个数呈正相关。S12: Determine the number of range extenders put in according to the degree of deviation; the degree of deviation is positively correlated with the number of range extenders.
在本实施例中，会根据SOC或需求功率与各自对应的预设阈值的偏差程度确定需要投入的增程器的个数。可以理解的是，SOC或需求功率与各自对应的预设阈值的偏差程度，都反映了车辆对输出功率的需求程度，当偏差程度越大时，则说明需要更多的输出功率，因此需要投入更多的增程器。In this embodiment, the number of range extenders to be inputted will be determined according to the degree of deviation between the SOC or the required power and the corresponding preset thresholds. It can be understood that the degree of deviation between the SOC or the required power and the respective preset thresholds reflects the degree of the vehicle's demand for output power. When the degree of deviation is larger, it means that more output power is required, so it is necessary to invest More range extenders.
本申请实施例提供的程器系统控制方法，应用于包括多个增程器的增程器系统，通过获取车辆电池的SOC或车辆行驶的需求功率，确定SOC或需求功率与各自对应的预设阈值的偏差程度，根据偏差程度确定投入增程器的个数，其中，偏差程度与增程器的个数呈正相关。相对于当前技术中，增程器系统可调节功率输出范围不足导致无法满足车辆运行需求，采用本技术方案，收集能反映车辆运行需求的车辆电池的SOC或车辆行驶的需求功率，根据其与预设阈值的偏差程度确定投入增程器的个数，在偏差越大时投入越多的增程器，以提供足够的输出功率，从而满足车辆运行需求，扩展车辆的功能多样性。The range extender system control method provided by the embodiment of the present application is applied to a range extender system including a plurality of range extenders. By acquiring the SOC of the vehicle battery or the required power of the vehicle running, the SOC or the required power and the respective preset values are determined. The deviation degree of the threshold value determines the number of range extenders to be put in according to the deviation degree, wherein the deviation degree is positively correlated with the number of range extenders. Compared with the current technology, the adjustable power output range of the range extender system is insufficient to meet the vehicle operation requirements. This technical solution is used to collect the SOC of the vehicle battery or the vehicle driving demand power that can reflect the vehicle operation requirements. The degree of deviation of the threshold value determines the number of range extenders to be put in. When the deviation is larger, more range extenders are put in to provide enough output power to meet the operating needs of the vehicle and expand the functional diversity of the vehicle.
可以理解的是，在具体实施中，增程器的体积很大，如果车辆的增程器系统包含过多的增程器则不利于空间布置，并且车辆的功能多样性也应当依托于实际，依托于车辆电池能够提供的输出功率，过多的增程器不会均被使用，也造成了资源的浪费。It can be understood that, in the specific implementation, the range extender is very large. If the range extender system of the vehicle contains too many range extenders, it is not conducive to the space arrangement, and the functional diversity of the vehicle should also be based on the actual situation. Relying on the output power that the vehicle battery can provide, too many range extenders will not be used, which also results in a waste of resources.
因此，在上述实施例的基础上，本实施例中的增程器系统包括两个增程器，增程器包括第一增程器和第二增程器；Therefore, on the basis of the above embodiment, the range extender system in this embodiment includes two range extenders, and the range extender includes a first range extender and a second range extender;
若SOC大于第一阈值，则确认不投入增程器；If the SOC is greater than the first threshold, it is confirmed that the range extender is not turned on;
若SOC小于第一阈值且大于第二阈值，则确认投入第一增程器；If the SOC is less than the first threshold and greater than the second threshold, confirming that the first range extender is turned on;
若SOC小于第二阈值，则确认投入第一增程器和第二增程器。If the SOC is less than the second threshold, it is confirmed that the first range extender and the second range extender are turned on.
本实施例以两个增程器组成增程器系统为例，在本实施例中，第一阈值和第二阈值代表了车辆电池的SOC，其中，第一阈值是较第二阈值大的值。在上述实施例中介绍了SOC的值是在0～1之间，值越大则代表着车辆电池的荷电状态越高，所存电量越高。因此，当SOC大于第一阈值时，表示车辆电池状态良好，能够提供足够的电量，不需要使用增程器。当SOC小于第一阈值且大于第二阈值时，表示车辆电池状态一般，车辆电池可能并不能满足全部的车辆需求，为了保证车辆电池处在稳定输出的环境，此时投入第一增程器，不仅可以与车辆电池一起为车辆提供输出，当可以用富余的功率为车辆电池充电。而当SOC小于第二阈值时，则表示车辆电池状态很差，车辆电池仅能提供一点输出或无法提供输出，此时需要投入第一增程器和第二增程器，共同为车辆提供能量，并且为车辆电池充电。In this embodiment, a range extender system composed of two range extenders is taken as an example. In this embodiment, the first threshold value and the second threshold value represent the SOC of the vehicle battery, wherein the first threshold value is a larger value than the second threshold value . In the above-mentioned embodiment, it is introduced that the value of SOC is between 0 and 1. The larger the value is, the higher the state of charge of the vehicle battery is, and the higher the stored power is. Therefore, when the SOC is greater than the first threshold, it indicates that the vehicle battery is in good condition and can provide sufficient power, and the range extender does not need to be used. When the SOC is less than the first threshold and greater than the second threshold, it means that the vehicle battery is in a normal state, and the vehicle battery may not be able to meet all vehicle needs. Not only can the output be provided for the vehicle together with the vehicle battery, but the vehicle battery can be charged with excess power. When the SOC is less than the second threshold, it means that the vehicle battery is in poor condition, and the vehicle battery can only provide a little output or can not provide output. At this time, the first range extender and the second range extender need to be invested to jointly provide energy for the vehicle , and charge the vehicle battery.
上述实施例是以SOC作为是否投入增程器的判断基准，本实施例还提供以需求功率作为判断基准的增程器系统控制方法。In the above-mentioned embodiment, the SOC is used as the criterion for determining whether to put in the range extender. The present embodiment also provides a range extender system control method that uses the required power as the determination criterion.
在本实施例中，若需求功率不大于车辆电池放电功率，则确认不投入增程器；In this embodiment, if the required power is not greater than the discharge power of the vehicle battery, it is confirmed that the range extender is not used;
若需求功率大于车辆电池放电功率，并且差值大于0且不大于第一增程器的输出功率，则确认投入第一增程器；If the required power is greater than the vehicle battery discharge power, and the difference is greater than 0 and not greater than the output power of the first range extender, confirming that the first range extender is turned on;
若差值大于第一增程器的输出功率，则确认投入第一增程器和第二增程器。If the difference is greater than the output power of the first range extender, confirm that the first range extender and the second range extender are turned on.
本实施例同样是以两台增程器组成的增程器系统为例，在本实施例中，是结合需求功率与单台增程器的输出功率共同确定投入增程器的个数。当需求功率不大于车辆电池放电功率时，说明车辆电池的输出能够满足车辆需求，此时无需使用增程器。而如果需求功率大于车辆电池放电功率，表示车辆电池无法满足车辆需求，此时需要投入增程器与车辆电池配合，共同满足车辆需求。在确认需要投入增程器后，根据还需要提供的输出功率确定投入几个增程器。当需求功率与车辆电池放电功率的差值大于0且不大于第一增程器的输出功率时，只需投入第一增程器即可满足需求，而如果差值大于第一增程器的输出功率，则还需要投入第二增程器，此时两台增程器共同补充输出。This embodiment also takes a range extender system composed of two range extenders as an example. In this embodiment, the number of input range extenders is determined by combining the required power and the output power of a single range extender. When the required power is not greater than the discharge power of the vehicle battery, it means that the output of the vehicle battery can meet the vehicle demand, and the range extender is not required at this time. If the required power is greater than the discharge power of the vehicle battery, it means that the vehicle battery cannot meet the vehicle demand. At this time, it is necessary to invest in the range extender to cooperate with the vehicle battery to jointly meet the vehicle demand. After confirming that the range extender needs to be put in, determine how many range extenders need to be put in according to the output power that needs to be provided. When the difference between the demanded power and the vehicle battery discharge power is greater than 0 and not greater than the output power of the first range extender, only the first range extender is required to meet the demand, and if the difference is greater than the output power of the first range extender If the output power is higher, a second range extender needs to be put in. At this time, the two range extenders jointly supplement the output.
本实施例提供的增程器系统控制方法，增程器系统包括第一増程器和第二增程器，在提高可调节输出功率的前提下，尽可能减少增程器的个数，以减少所占空间，便于车辆的集成布置。并且，本实施例还提供了该增程器系统具体确认投入增程器个数的判断方法，能够根据车辆需求，合适的调整投入增程器的个数，实现对车辆电池的充电和车辆的功能。In the method for controlling a range extender system provided in this embodiment, the range extender system includes a first range extender and a second range extender. On the premise of increasing the adjustable output power, the number of range extenders is Reduce the occupied space and facilitate the integrated layout of the vehicle. In addition, the present embodiment also provides a method for determining the number of range extenders put in by the range extender system, which can appropriately adjust the number of range extenders put in according to the needs of the vehicle, so as to realize the charging of the vehicle battery and the operation of the vehicle. Function.
在上述实施例中介绍到车辆的VCU能够通过CAN与诊断接口连接，实现对故障的监测。在具体实施中，车辆的故障影响的车辆行驶的安全，如果在车辆存在故障时仍投入增程器进行使用，容易导致更严重的事故发生，对驾驶人员的安全造成威胁。In the above-mentioned embodiments, the VCU of the vehicle can be connected to the diagnosis interface through CAN, so as to realize the monitoring of the fault. In a specific implementation, if the vehicle failure affects the driving safety of the vehicle, if the range extender is still put into use when the vehicle has a failure, it will easily lead to more serious accidents and threaten the safety of drivers.
因此，在上述实施例的基础上，在本实施例中，在确认是否投入增程器的步骤之前，还包括：Therefore, on the basis of the above embodiment, in this embodiment, before the step of confirming whether to put in the range extender, the method further includes:
获取整车状态信息；Get vehicle status information;
根据整车状态信息判断车辆是否存在故障，若存在，则禁止投入增程器，若不存在，则进入确认是否投入增程器的步骤。According to the vehicle status information, it is judged whether the vehicle has a fault, if so, it is forbidden to input the range extender, if not, the step of confirming whether to input the range extender is entered.
本实施例提供的增程器系统控制方法，在确认是否投入增程器之前，先判断车辆是否存在故障，如果存在故障则禁止投入增程器，以避免事故的发生。可以理解的是，在车辆行驶中，有些故障会影响到车辆行驶安全，此时需要禁止投入增程器。而有些故障危险程度较小，并不会影响到车辆行驶安全，此时是可以投入增程器的。因此在具体实施中，可以将车辆可能发生的故障进行分级，根据故障的级别确认是否投入增程器。In the method for controlling the range extender system provided by this embodiment, before confirming whether to put the range extender into operation, it is judged whether the vehicle has a fault, and if there is a fault, the operation of the range extender is prohibited to avoid accidents. It can be understood that some faults will affect the safety of the vehicle while the vehicle is running, and it is necessary to prohibit the use of the range extender at this time. Some faults are less dangerous and will not affect the driving safety of the vehicle. At this time, the range extender can be used. Therefore, in the specific implementation, the possible faults of the vehicle can be classified, and it can be confirmed whether to use the range extender according to the fault level.
可以理解的是，增程器的长时间工作会降低增程器的使用寿命。为了实现对增程器的保护，在本实施例中，在仅投入第一增程器的情况下，还包括：It can be understood that the long-term operation of the range extender will reduce the service life of the range extender. In order to realize the protection of the range extender, in this embodiment, when only the first range extender is put into use, it also includes:
获取第一增程器和第二增程器的工作时长；Obtain the working hours of the first range extender and the second range extender;
若第一增程器的工作时长大于第二增程器的工作时长且差值不小于阈值，则将第二增程器作为第一增程器投入；If the working duration of the first range extender is greater than the working duration of the second range extender and the difference is not less than the threshold value, the second range extender is put into operation as the first range extender;
其中，第一增程器为上次投入的增程器。Wherein, the first range extender is the range extender put in last time.
本实施例通过设定阈值，在两台增程器的工作时长差值超出阈值时，则更换增程器投入。以阈值为500h为例，在具体实施中，当需要投入一台增程器时，会默认再次使用上一次投入使用的增程器，例如此增程器为第一增程器，VCU会判断第一增程器的工作时长是否大于第二增程器的工作时长且差值大于500h，如果大于500h，则替换使用第二增程器提供输出，如果没有超出大于500h，则继续由第一增程器提供输出。本实施例通过轮换的方式，使第一增程器和第二增程器替换工作，避免了一台增程器的长时间使用导致降使用寿命低。In this embodiment, by setting a threshold, when the difference between the working hours of the two range extenders exceeds the threshold, the range extender is replaced. Taking the threshold value of 500h as an example, in the specific implementation, when a range extender needs to be put in, the range extender that was put into use will be used again by default. For example, this range extender is the first range extender, and the VCU will judge it. Whether the working duration of the first range extender is greater than the working duration of the second range extender and the difference is greater than 500h, if it is greater than 500h, then use the second range extender instead to provide the output, if it does not exceed 500h, continue to use the first range extender The range extender provides the output. In this embodiment, the first range extender and the second range extender are replaced by means of rotation, which avoids the long-term use of one range extender resulting in a shortened service life.
在具体实施中，增程器的投入个数，以及每台增程器提供输出的不同都会造成油耗的不同。为了在满足需求的前提下尽可能减少油耗，在本实施例中，增程器系统控制方法还包括：In specific implementation, the input number of range extenders and the difference in output provided by each range extender will result in different fuel consumption. In order to reduce the fuel consumption as much as possible on the premise of meeting the demand, in this embodiment, the control method of the range extender system further includes:
根据增程器的油耗特性，确定特定功率输出点；Determine the specific power output point according to the fuel consumption characteristics of the range extender;
若需求功率不大于特定功率输出点，则控制第一增程器与第二增程器等功率输出以满足需求功率；If the required power is not greater than the specific power output point, control the power output of the first range extender and the second range extender to meet the required power;
若大于，则控制第一增程器全功率输出，第二增程器补充剩余需求功率输出以满足需求功率。If it is greater than that, the full power output of the first range extender is controlled, and the second range extender supplements the remaining demand power output to meet the demand power.
需要说明的是，本实施例对油耗控制的前提是第一增程器与第二增程器均被投入使用，以一台增程器的最大输出功率为37kw为例。It should be noted that the premise of the fuel consumption control in this embodiment is that both the first range extender and the second range extender are put into use, and the maximum output power of one range extender is 37kw as an example.
当需要增程器补充的功率小于37kw时，此时投入一台增程器即可，当超出74kw时，需要两台增程器以最大功率输出，当超出37kw小于74kw时，此时则可以根据油耗确定是两台增程器等功率输出还是以一台增程器以最大功率输出，另一台补充剩余输出。本实施例还提供一种具体的确定方法，首先，增程器系统的功率输出计算公式为：When the power that needs to be supplemented by the range extender is less than 37kw, one range extender can be put in at this time. When it exceeds 74kw, two range extenders are required to output the maximum power. When it exceeds 37kw and less than 74kw, it can be According to the fuel consumption, determine whether the two range extenders output the same power or use one range extender to output the maximum power, and the other to supplement the remaining output. This embodiment also provides a specific determination method. First, the power output calculation formula of the range extender system is:
Wt＝(K1+K2)W0Wt =(K1 +K2 )W0
其中，Wt为需要增程器补充的目标输出功率，K1、K2为单台增程器输出比例，W0为单台增程器输出功率。Among them, Wt is the target output power that needs to be supplemented by the range extender, K1 and K2 are the output ratio of a single range extender, and W0 is the output power of a single range extender.
根据增程器的油耗特性，确定特定功率输出点：According to the fuel consumption characteristics of the range extender, determine the specific power output point:
Q+O＝2*OmQ+O=2*Om
其中，Q为37kw输出所需的油耗量，O为满足目标输出功率剩余输出功率所需的油耗量，Om为等分目标功率所需的油耗量。确定此时的控制点为(Ta,Sa)，Ta为输出扭矩，Sa为输出转速，根据功率的计算公式Among them, Q is the fuel consumption required for 37kw output, O is the fuel consumption required to meet the target output power and the remaining output power, and Om is the fuel consumption required to equally divide the target power. Determine the control point at this time as (Ta , Sa ), Ta is the output torque, Sa is the output speed, according to the calculation formula of power
得出此时的特定功率输出点Pa，当实际控制中，P小于或等于Pa时，选择控制第一增程器与第二增程器等功率输出以满足需求功率，此时K1＝K2。当P大于Pa时，此时选择一台增程器全功率输出，另一台补充剩余需求功率。The specific power output point Pa at this time is obtained. When P is less than or equal to Pa in the actual control, the first range extender and the second range extender are selected to control the power output to meet the required power, and at this time K1 =K2 . When P is greater than Pa , select one range extender to output full power at this time, and the other to supplement the remaining required power.
本实施例通过调整每台增程器的输出功率，以在满足需求功率的前提下尽可能降低油耗。In this embodiment, the output power of each range extender is adjusted to reduce fuel consumption as much as possible on the premise of meeting the required power.
在车辆行驶中，如果增程器系统发生故障则无法继续提供输出，因此在本实施例中：若增程器系统发生故障，则降低需求功率。When the vehicle is running, if the range extender system fails, the output cannot continue to be provided. Therefore, in this embodiment: if the range extender system fails, the required power is reduced.
在具体实施中，如果车辆的增程器系统发生故障，此时则无法继续投入增程器使用，因此需要及时通知驾驶人员减少行车需求，降低需求功率。可以理解的是，增程器系统的故障也分为多种情况，在其他实施例中，如果只投入了一台增程器，而增程器系统的故障为此增程器故障，此时则可以切换为其他增程器继续提供输出，在安全驾驶的前提下也无需降低需求功率。In a specific implementation, if the range extender system of the vehicle fails, the range extender cannot be put into use at this time, so the driver needs to be notified in time to reduce the driving demand and reduce the demand power. It can be understood that the fault of the range extender system is also divided into various situations. In other embodiments, if only one range extender is put in, and the fault of the range extender system is the fault of the range extender, then Then it can be switched to other range extenders to continue to provide output, and there is no need to reduce the required power under the premise of safe driving.
