The invention provides a hybrid power vehicle, an engine starting control method thereof, a medium and a controller, and the method comprises the steps that after engine starting conditions are met, the engine oil temperature and the cooling liquid temperature of an engine are obtained; searching a preset corresponding relation according to the engine oil temperature and the cooling liquid temperature to obtain the working loss torque of the engine; and an ISG motor of the hybrid vehicle is controlled according to the work loss torque, so that starting of an engine is achieved. Therefore, the working loss torque of the engine is determined according to the engine oil temperature and the cooling liquid temperature of the engine, then starting control is carried out based on the working loss torque, the accuracy of engine starting control can be improved, and the working smoothness of the ISG motor is guaranteed.
本公开提出了一种混合动力车辆及其发动机启动控制方法以及介质、控制器,方法包括:发动机启动条件满足后,获取发动机的机油温度和冷却液温度;根据机油温度和冷却液温度,查找预设对应关系得到发动机的工作损失扭矩;根据工作损失扭矩对混合动力车辆的ISG电机进行控制,以实现发动机的启动。由此,通过发动机的机油温度和冷却液温度确定发动机的工作损失扭矩,进而基于该工作损失扭矩进行启动控制,可提高发动机启动控制的准确性,保证ISG电机的工作平顺性。
