The invention discloses a starter control method and system for a hybrid power vehicle and a hybrid power vehicle. The method comprises the following steps that: the state parameter of a starting power supply loop is obtained, and whether the starting power supply loop has a fault or not is determined according to the state parameter; a starting mode of a starter is obtained, wherein the startingmode of the starter comprises a driving starting mode and a parking starting mode; if the starter adopts the driving starting mode and the starting power supply loop does not fail, a starting switch is controlled to be switched off, a power limiting instruction is sent to a low-voltage load, and the starter is controlled to start an engine after first preset time; and if the starter adopts the parking starting mode and the starting power supply loop does not fail, the starting switch is controlled to be kept switched off, and the starter is controlled to start the engine. The starter control method provided by the embodiment of the invention is beneficial to improving the voltage stability of the whole vehicle, preventing the starting voltage drop of the starter from influencing the low-voltage load work, reducing the production cost and improving the operation safety of the whole vehicle.
本发明公开了一种混合动力车辆的起动机控制方法、系统及混合动力车辆,方法包括以下步骤:获取起机供电回路的状态参数,根据状态参数确定起机供电回路是否发生故障;获取起动机的起机模式,起动机起机模式包括行车起机模式和停车起机模式;若起动机采用行车起机模式且起机供电回路未发生故障,则控制起机开关断开,并对低压负载发出功率限制指令,经过第一预设时间,控制起动机起动发动机;若起动机采用停车起机模式且起机供电回路未发生故障,则控制起机开关保持闭合,并控制起动机起动发动机。本发明实施例提供的起动机控制方法有利于提高整车电压稳定性,避免起动机的起动电压降影响低压负载工作,降低生产成本,提升整车运行安全性。
