The invention relates to the technical field of hybrid power vehicles, and discloses a hybrid power vehicle engine torque correction method and device, a vehicle and a medium, and the method comprises the steps that when a target hybrid power vehicle works in a series mode, the target engine torque and the target generator rotating speed are obtained; after it is monitored that the current rotating speed of the generator reaches the target rotating speed of the generator, the target torque of the engine is corrected, and the target correction amount is obtained; and the target correction amount and the engine target torque before correction are superposed, and the corrected engine target torque is obtained. The engine target torque is corrected by utilizing the corresponding relation between the actual torque of the generator and the actual torque of the engine and calculating the actual torque of the engine through the actual torque of the generator, so that it is guaranteed that the actual torque of the engine reaches the initial expected target torque of the engine, and overcharge or overdischarge of a battery is avoided; and user experience is improved.
本发明涉及混合动力车辆技术领域,公开了混合动力车辆发动机扭矩修正方法、装置、车辆及介质,该方法包括:在目标混合动力车辆工作在串联模式时,获取发动机目标扭矩和发电机目标转速;在监测到发电机的当前转速达到发电机目标转速后,对发动机目标扭矩进行修正,得到目标修正量;将目标修正量与修正前的发动机目标扭矩进行叠加,得到修正后的发动机目标扭矩。本发明通过利用发电机的实际扭矩与发动机实际扭矩的对应关系,通过发电机实际扭矩计算发动机实际扭矩来对发动机目标扭矩进行修正,以保障发动机实际扭矩达到最初期望的发动机目标扭矩,避免电池出现过充或过放,提升用户体验。
