背景技术Background technique
目前环境问题越来越受到人们的关注，绿色出行倍受欢迎，电动汽车的推广也势在必行。对于电动汽车来说，续航能力是阻碍其推广的一个重要原因，电动汽车只能停泊在充电站进行充电，这样严重影响了电动汽车的运行安排。在电动汽车中增加增程器系统，可以实现其在运行过程中充电，能够有效的解决电动汽车的续航问题。At present, environmental issues are attracting more and more people's attention, green travel is very popular, and the promotion of electric vehicles is imperative. For electric vehicles, battery life is an important reason hindering its popularization. Electric vehicles can only be parked at charging stations for charging, which seriously affects the operation arrangement of electric vehicles. Adding a range extender system to the electric vehicle can realize its charging during operation, which can effectively solve the battery life problem of the electric vehicle.
现有的增程器系统由发动机与启动发电一体机组成，增程器系统的散热、系统低压模块的供电稳定性、发电控制策略的制定、将发电机三相电流转化为直流电对动力电池进行充电等过程均需要发电机控制器来参与。此外，发电机控制器还要用于控制驱动电机的运转以保证车辆运行。也就是说，发电机控制器同时参与增程器系统和驱动系统的相关工作，这样发电机控制器的占用率很高，将会导致发电机控制器的控制性能下降，从而导致增程器系统的稳定性降低、动力电池使用寿命缩短。The existing range extender system is composed of an engine and a starter generator. The heat dissipation of the range extender system, the stability of the power supply of the low-voltage module of the system, the formulation of the power generation control strategy, and the conversion of the three-phase current of the generator into DC power for the power battery Processes such as charging require the participation of the generator controller. In addition, the generator controller is also used to control the operation of the drive motor to ensure the operation of the vehicle. That is to say, the generator controller participates in the work related to the range extender system and the drive system at the same time, so that the occupancy rate of the generator controller is high, which will lead to a decrease in the control performance of the generator controller, which will lead to the failure of the range extender system. The stability of the battery is reduced, and the service life of the power battery is shortened.

图2是根据一示例性实施例示出的一种用于电动汽车的增程器系统的发电控制方法的流程图，其中，该方法可以应用于发电辅助控制器，例如，图1所示的发电辅助控制器10。如图2所示，该方法可以包括以下步骤。Fig. 2 is a flowchart showing a power generation control method for a range extender system of an electric vehicle according to an exemplary embodiment, wherein the method can be applied to a power generation auxiliary controller, for example, the power generation control method shown in Fig. 1 Auxiliary controller 10. As shown in Fig. 2, the method may include the following steps.
在步骤201中，发电辅助控制器获取电动汽车的目标发电模式。In step 201, the power generation auxiliary controller acquires the target power generation mode of the electric vehicle.
在本公开中，该目标发电模式可以为以下模式中的一项：纯电动模式、里程模式和经济模式。In the present disclosure, the target power generation mode may be one of the following modes: pure electric mode, mileage mode and economical mode.
在一种实施方式中，在接收到发电模式开关信号时，可以根据该发电模式开关信号，确定目标发电模式，其中，该发电模式开关信号用于指示目标发电模式。该发电模式开关信号可以与发电模式开关的挡位状态相对应，发电模式开关可以具有纯电动模式挡位、里程模式挡位和经济模式挡位。在驾驶员评估行驶里程模式的情况下，驾驶员可以通过手动操作该发电模式开关来实现挡位的切换。示例地，当驾驶根据评估里程需要电动汽车进入纯电动模式时，可以通过将发电模式开关置位到纯电动模式挡位来触发电动汽车进入纯电动模式。发电模式开关可以与发电辅助控制器电连接，当驾驶员将发电模式开关置位后，可以向发电辅助控制器发送发电模式开关信号，然后由发电辅助控制器接收该发电模式开关信号。In an implementation manner, when a power generation mode switch signal is received, the target power generation mode may be determined according to the power generation mode switch signal, wherein the power generation mode switch signal is used to indicate the target power generation mode. The power generation mode switch signal may correspond to the gear state of the power generation mode switch, and the power generation mode switch may have a pure electric mode gear, a mileage mode gear and an economical mode gear. In the case of the driver evaluating the mileage mode, the driver can manually operate the power generation mode switch to switch gears. For example, when driving requires the electric vehicle to enter the pure electric mode according to the estimated mileage, the electric vehicle can be triggered to enter the pure electric mode by setting the power generation mode switch to the pure electric mode gear. The power generation mode switch can be electrically connected with the power generation auxiliary controller. When the driver sets the power generation mode switch, he can send a power generation mode switch signal to the power generation auxiliary controller, and then the power generation auxiliary controller receives the power generation mode switch signal.
示例地，当评估里程在200km以下时，驾驶员可以将发电模式开关置位到经济模式挡位。在经济模式下，电动汽车优先消耗整车电量，这样可以节约汽油、降低成本。For example, when the estimated mileage is below 200km, the driver can set the power generation mode switch to the gear of the economic mode. In the economical mode, electric vehicles give priority to the consumption of the entire vehicle's electricity, which can save gasoline and reduce costs.
又示例地，当评估里程在200km以上时，驾驶员可以将发电模式开关置位到里程模式挡位。在里程模式下，电动汽车保持用电平衡，尽量延长续航里程。As another example, when the estimated mileage is over 200km, the driver may set the power generation mode switch to the mileage mode gear. In the mileage mode, the electric vehicle maintains a balance of power consumption and extends the cruising range as much as possible.
又示例地，当电动汽车在城市内中短距离行驶时，驾驶员可以将发电模式开关置位到纯电动模式挡位。在纯电动模式下，电动汽车主要以电驱动，在电量很低的情况下通过增程器系统来补充电力，从而满足车辆的实际运行需求。As another example, when the electric vehicle is traveling a short distance in the city, the driver can set the power generation mode switch to the pure electric mode gear. In the pure electric mode, the electric vehicle is mainly driven by electricity, and the range extender system is used to supplement the power when the power is low, so as to meet the actual operation needs of the vehicle.
在另一种实施方式中，在未接收到发电模式开关信号时，可以将指定的发电模式确定为目标发电模式。也就是说，在驾驶员未评估行驶里程模式的情况下，发电模式开关信号未置位，这样发电辅助控制器将无法接收到发电模式信号，此时，可以确定目标发电模式为指定的发电模式，例如，经济模式。In another implementation manner, when the power generation mode switch signal is not received, the designated power generation mode may be determined as the target power generation mode. That is to say, when the driver does not evaluate the mileage mode, the power generation mode switch signal is not set, so the power generation auxiliary controller will not be able to receive the power generation mode signal. At this time, it can be determined that the target power generation mode is the designated power generation mode , for example, the economy model.
此外，当发电辅助控制器获取到电动汽车的目标发电模式之后，可以输出该目标发电模式，这样，驾驶员可以清楚地知道电动汽车的当前发电状况。示例地，可以在发电模式开关上设置有指示灯，当目标发电模式被获取后，发电辅助控制器可以控制发电模式开关点亮对应的目标发电模式指示灯。例如，可以通过指示灯的颜色来显示对应的发电模式。又示例地，可以在发电模式开关上设置有显示屏，当目标发电模式确定后，可以将该目标发电模式输出到该显示屏。In addition, after the power generation auxiliary controller obtains the target power generation mode of the electric vehicle, it can output the target power generation mode, so that the driver can clearly know the current power generation status of the electric vehicle. For example, an indicator light may be provided on the power generation mode switch, and when the target power generation mode is acquired, the auxiliary power generation controller may control the power generation mode switch to light up the corresponding target power generation mode indicator light. For example, the corresponding power generation mode can be displayed by the color of the indicator light. As another example, a display screen may be provided on the power generation mode switch, and when the target power generation mode is determined, the target power generation mode may be output to the display screen.
在步骤202中，发电辅助控制器将目标发电模式发送给发电机控制器。In step 202, the power generation assist controller sends the target power generation mode to the generator controller.
在步骤203中，发电辅助控制器接收发电机控制器发送的目标发电功率。In step 203, the power generation auxiliary controller receives the target power generation power sent by the generator controller.
在本公开中，该目标发电功率是发电机控制器根据目标发电模式和动力电池的剩余电量来确定的。In the present disclosure, the target power generation is determined by the generator controller according to the target power generation mode and the remaining power of the power battery.
如图3A和图3B所示，发电机控制器可以通过以下方式来确定目标发电功率：在目标发电模式为经济模式或里程模式的情况下，当剩余电量大于或等于第一预设阈值时，确定目标发电功率为零，其中，在所述目标发电功率为零时，所述增程器系统停止工作；在目标发电模式为经济模式的情况下，在剩余电量小于第一预设阈值、且大于或等于第二预设阈值时，将第一发电功率作为所述目标发电功率；在目标发电模式为里程模式的情况下，在剩余电量小于第一预设阈值、且大于或等于第二预设阈值时，将第一发电功率作为所述目标发电功率；在目标发电模式为经济模式情况下，在剩余电量小于第二预设阈值、且大于或等于第三预设阈值时，将第三发电功率作为所述目标发电功率；在目标发电模式为里程模式情况下，在剩余电量小于第二预设阈值、且大于或等于第三预设阈值时，将第四发电功率作为所述目标发电功率；在目标发电模式为经济模式的情况下，在剩余电量小于第三预设阈值时，将第五发电功率作为所述目标发电功率；在目标发电模式为里程模式的情况下，在剩余电量小于第三预设阈值时，将第六发电功率作为所述目标发电功率。As shown in FIGS. 3A and 3B , the generator controller can determine the target power generation in the following manner: when the target power generation mode is the economy mode or the mileage mode, when the remaining power is greater than or equal to the first preset threshold, Determining that the target power generation is zero, wherein, when the target power generation is zero, the range extender system stops working; when the target power generation mode is the economic mode, when the remaining power is less than the first preset threshold, and When it is greater than or equal to the second preset threshold, the first generated power is used as the target generated power; when the target power generation mode is the mileage mode, when the remaining power is less than the first preset threshold and greater than or equal to the second preset When the threshold is set, the first generated power is used as the target generated power; when the target power generation mode is the economic mode, when the remaining power is less than the second preset threshold and greater than or equal to the third preset threshold, the third The generated power is used as the target generated power; when the target generated power mode is the mileage mode, when the remaining power is less than the second preset threshold and greater than or equal to the third preset threshold, the fourth generated power is used as the target generated power Power; when the target power generation mode is the economic mode, when the remaining power is less than the third preset threshold, the fifth power generation power is used as the target power generation power; when the target power generation mode is the mileage mode, when the remaining power When it is less than the third preset threshold, the sixth generated power is used as the target generated power.
在本公开中，剩余电量可以表示动力电池的剩余电量百分比。示例地，第一预设阈值为85％、第二预设阈值为65％、第三预设阈值为20％。此外，第三发电功率大于第一发电功率，第四发电功率大于第二发电功率，第五发电功率大于第三发电功率，第六发电功率大于第四发电功率。示例地，第一发电功率为30KW、第二发电功率为50KW、第三发电功率为50KW、第四发电功率为80KW、第五发电功率为110KW、第六发电功率为110KW。另外需要说明的是，第一发电功率和第二发电功率可以相等，也可以不相等。同样地，第三发电功率和第四发电功率可以相等，也可以不相等；第五发电功率和第六发电功率可以相等，也可以不相等。另外，需要说明的是，在目标发电功率为零时，增程器系统停止工作。也就是说，在目标发电模式为经济模式或里程模式的情况下，当剩余电量大于或等于第一预设阈值时，增程器系统停止工作。In the present disclosure, the remaining power may represent the percentage of the remaining power of the power battery. For example, the first preset threshold is 85%, the second preset threshold is 65%, and the third preset threshold is 20%. In addition, the third generated power is greater than the first generated power, the fourth generated power is greater than the second generated power, the fifth generated power is greater than the third generated power, and the sixth generated power is greater than the fourth generated power. For example, the first power generation is 30KW, the second power generation is 50KW, the third power generation is 50KW, the fourth power generation is 80KW, the fifth power generation is 110KW, and the sixth power generation is 110KW. In addition, it should be noted that the first generated power and the second generated power may be equal or unequal. Likewise, the third generated power may be equal to the fourth generated power, or may not be equal; the fifth generated power may be equal to the sixth generated power, or may not be equal. In addition, it should be noted that when the target power generation is zero, the range extender system stops working. That is to say, when the target power generation mode is the economy mode or the mileage mode, when the remaining power is greater than or equal to the first preset threshold, the range extender system stops working.
此外，在所述目标发电模式为经济模式的情况下，在发动机按照第一发电功率对应的目标转速进行运转、且剩余电量变为大于或等于第一中间阈值时，确定目标发电功率为零；在所述目标发电模式为里程模式的情况下，在发动机按照第二发电功率对应的目标转速进行运转、且剩余电量变为大于或等于第一中间阈值时，确定目标发电功率为零；在所述目标发电模式为经济模式的情况下，在发动机按照第三发电功率对应的目标转速进行运转、且剩余电量变为大于或等于第二中间阈值时，将第一发电功率作为所述目标发电功率；在所述目标发电模式为里程模式的情况下，在发动机按照第四发电功率对应的目标转速进行运转、且剩余电量变为大于或等于第二中间阈值时，将第二发电功率作为所述目标发电功率；在所述目标发电模式为经济模式的情况下，在发动机按照第五发电功率对应的目标转速进行运转、且剩余电量变为大于或等于第三中间阈值时，将第三发电功率作为所述目标发电功率；在所述目标发电模式为里程模式的情况下，在发动机按照第六发电功率对应的目标转速进行运转、且剩余电量变为大于或等于第三中间阈值时，将第四发电功率作为所述目标发电功率。In addition, when the target power generation mode is the economic mode, when the engine operates at the target speed corresponding to the first power generation power and the remaining power becomes greater than or equal to the first intermediate threshold value, it is determined that the target power generation power is zero; In the case where the target power generation mode is the mileage mode, when the engine operates according to the target speed corresponding to the second power generation power and the remaining power becomes greater than or equal to the first intermediate threshold value, it is determined that the target power generation power is zero; When the target power generation mode is the economical mode, when the engine is running at the target speed corresponding to the third power generation and the remaining power becomes greater than or equal to the second intermediate threshold, the first power generation is taken as the target power generation ; When the target power generation mode is the mileage mode, when the engine operates at the target speed corresponding to the fourth power generation power and the remaining power becomes greater than or equal to the second intermediate threshold value, the second power generation power is used as the Target power generation; when the target power generation mode is the economic mode, when the engine is running at the target speed corresponding to the fifth power generation and the remaining power becomes greater than or equal to the third intermediate threshold, the third power generation As the target power generation; when the target power generation mode is the mileage mode, when the engine is running at the target speed corresponding to the sixth power generation and the remaining power becomes greater than or equal to the third intermediate threshold, the second Four generating powers are used as the target generating power.

Exemplarily, the first intermediate threshold is 90%, the second intermediate threshold is 70%, and the third intermediate threshold is 25%.
如图3C所示，发电机控制器还可以通过以下方式来确定目标发电功率：在目标发电模式为纯电动模式的情况下，在剩余电量大于或等于第三预设阈值时，确定目标发电功率为零；在目标发电模式为纯电动模式的情况下，在剩余电量小于第三预设阈值时，将目标发电模式切换至经济模式，并将第五发电功率作为所述目标发电功率。As shown in Figure 3C, the generator controller can also determine the target power generation in the following manner: in the case that the target power generation mode is pure electric mode, when the remaining power is greater than or equal to the third preset threshold, determine the target power generation is zero; if the target power generation mode is the pure electric mode, when the remaining power is less than the third preset threshold, switch the target power generation mode to the economic mode, and use the fifth power generation power as the target power generation power.
此外，在目标发电模式从纯电动模式切换至经济模式后，当剩余电量变为大于第三中间阈值时，将发电模式切换至纯电动模式。In addition, after the target power generation mode is switched from the pure electric mode to the economical mode, when the remaining power becomes greater than the third intermediate threshold, the power generation mode is switched to the pure electric mode.
当目标发电功率确定之后，增程器系统可以根据目标发电模式和电池剩余电量进入相应功率的发电状态，可以在保证续航里程、车辆动力性需求和电池性能的前提下，进一步优先使用动力电池的电量，这样，可以降低油耗，节约成本，提高动力电池的使用寿命。When the target power generation power is determined, the range extender system can enter the power generation state of the corresponding power according to the target power generation mode and the remaining battery power, and can further prioritize the use of the power battery on the premise of ensuring the cruising range, vehicle power requirements and battery performance. In this way, fuel consumption can be reduced, costs can be saved, and the service life of the power battery can be improved.

在本公开中，该预设的发电条件可以为目标发电功率大于零。当目标发电功率大于零时，表示动力电池需要充电，此时，发电辅助控制器可以控制预充接触器吸合，为后续的动力电池的预充电做好准备。In the present disclosure, the preset power generation condition may be that the target power generation is greater than zero. When the target generating power is greater than zero, it means that the power battery needs to be charged.

The power generation auxiliary controller can control the pre-charging contact when the target power generation meets the preset power generation conditions The contactor is closed to prepare for the pre-charging of the power battery. The generator controller can pre-charge the power battery after the pre-charging contactor is closed, and control the generator to drive the engine to the starting state after the pre-charging is completed, that is The starting of the engine does not require an additional starter, which not only simplifies the structure of the range extender system and reduces the cost, but also eliminates the failure of the engine to start due to the problem of the starter. In addition, the generator controller does not participate in the control of the drive motor of the electric vehicle, which can reduce the occupancy rate of the generator controller, charge the power battery more stably during the operation of the electric vehicle, and increase the service life of the power battery , to extend the cruising range.
