The invention relates to a low-temperature cold starting method for a diesel engine hybrid vehicle, and belongs to the field of diesel engine hybrid vehicle starting control. According to the cold start method, cold start is executed under the three conditions of no power shortage alarm of high-voltage power and low-voltage power, no power shortage alarm of high-voltage power, power shortage alarm of low-voltage battery, power shortage alarm of high-voltage power and no power shortage alarm of low-voltage battery. The invention provides a low-temperature cold starting method for a diesel engine hybrid vehicle, which comprehensively considers the starting characteristic (ISG motor dragging starting) of an APU (Auxiliary Power Unit) and reasonable distribution and utilization of high-voltage electricity and low-voltage electricity.

    本发明涉及一种柴油机混动车辆低温冷起动方法,属于柴油机混合动力车辆起动控制领域。本发明将冷起动方法分为:高压电、低压电均无缺电报警,高压电无缺电报警、低压电池有缺电报警,高压电有缺电报警、低压电池无缺电报警这三种情况分别执行冷启动。本发明提供一种柴油机混动车辆低温冷起动方法,综合考虑了APU起动的特点(ISG电机拖动起动),以及高压电和低压电的合理分配利用。
