The invention discloses a hybrid power system engine control method and device, and relates to the technical field of engine control. Whether an engine starting signal exists or not is detected; if the engine starting signal exists, the starting torque of the first motor and the resistance torque of the engine are obtained; determining a first reaction torque output by a second motor according to the obtained starting torque of the first motor and the resistance torque of the engine; if the rotating speed of the engine reaches the ignition rotating speed, the combustion torque of the engine is obtained; and according to the combustion torque of the engine, second reaction torque output by the second motor is determined. Therefore, when the engine is started, the reaction torque applied by the second motor is used for balancing, so that the wheel edge resultant torque approaches to zero, and the impact vibration caused by the starting of the engine to a vehicle body is improved.
本发明公开一种混合动力系统发动机控制方法及装置,涉及发动机控制技术领域。本发明通过检测是否存在发动机启动信号;若存在发动机启动信号,则获取第一电机的启动扭矩以及发动机的阻力矩;根据获取的第一电机的启动扭矩、发动机的阻力矩,确定第二电机输出的第一反扭矩;若发动机的转速达到点火转速,则获取发动机的燃烧扭矩;根据发动机的燃烧扭矩,确定第二电机输出的第二反扭矩。如此,在发动机启动时,通过第二电机施加的反扭矩进行平衡,使轮边合扭矩趋近于零,以改善发动机启动对车身造成的冲击振动。
