Provided are combustion engine starter systems and methods. A vehicle includes a combustion engine configured to crank start via torque applied to a crankshaft. The vehicle also includes a first electric machine to drive vehicle wheels powered by a high-voltage power source and coupled to the crankshaft and a second electric machine powered by a low-voltage power source and coupled to the crankshaft. The vehicle further includes a controller programmed to monitor a battery state of charge (SOC) and a voltage of the high-voltage power source. The controller is also programmed to activate only the second electric machine to attempt to crank start the engine in response to either of the SOC or the voltage being less than a predetermined threshold, and activate the first electric machine to attempt to crank start the engine in response to each of the SOC and the voltage being greater than a predetermined threshold.

    本公开提供了“燃烧发动机起动机系统和方法”。一种车辆包括燃烧发动机,所述燃烧发动机被配置为经由施加到曲轴的扭矩来转动起动。所述车辆还包括:用于驱动车轮的第一电机,所述第一电机由高压电源供电并且联接到所述曲轴;以及第二电机,所述第二电机由低压电源供电并且联接到所述曲轴。所述车辆还包括控制器,所述控制器被编程为监测所述高压电源的电池荷电状态(SOC)和电压。所述控制器还被编程为响应于所述SOC或所述电压中的任一者小于预定阈值而仅激活所述第二电机以尝试转动起动所述发动机,以及响应于所述SOC和所述电压中的每一者大于预定阈值而激活所述第一电机以尝试转动起动所述发动机。
