The invention provides an engine starting method and device, a vehicle and a hybrid power controller applied to the vehicle. The method comprises the steps that a target available torque value determined by a belt starting generator based on a target current value and a target voltage value is received; the target current value is an expected current value after a preset time period, and the target voltage value is a voltage value after the preset time period; and based on the target available torque value and a preset starting required torque value of the belt starting generator, determining to start the engine through the belt starting generator or the starter. Based on the target available torque value and the preset torque value required for starting, it is determined that the generator or the starter starts the engine through the belt, it is guaranteed that the engine can be started, and under the whole vehicle pure electric running working condition, the engine can be started more stably. The problem that the engine fails to start due to the fact that the current available torque value generated by the belt starting generator possibly cannot continuously push the engine within a period of time is solved, and the stability of the vehicle is improved.

    本发明提供了一种发动机启动方法、装置及车辆,应用于车辆的混合动力控制器,方法包括:接收皮带启动发电机基于目标电流值和目标电压值确定的目标可用扭矩值;目标电流值为预设时间段后的期望电流值,目标电压值为预设时间段后的电压值;基于目标可用扭矩值和皮带启动发电机的预设启动所需扭矩值,确定通过皮带启动发电机或者起动机启动发动机。本发明基于该目标可用扭矩值和预设启动所需扭矩值,确定通过皮带启动发电机或起动机启动发动机,保证了发动机可以启动,使得在整车纯电行驶工况下,避免了由于皮带启动发电机发出的当前的可用扭矩值可能无法在一段时间内持续推动发动机,而导致发动机启动失败的问题,提高了车辆的稳定性。
