The invention relates to the technical field of engine control, and provides an engine speed regulation method based on parking charging and a parking charging method and device.The method comprises the steps that the actual rotating speed of an engine is obtained, and the rotating speed difference between the actual rotating speed and the pre-stored target rotating speed is calculated; engine demand torque and motor control torque are calculated according to the rotating speed difference; acquiring actual torque and starting torque of the motor, and acquiring slope limit data according to the actual torque of the motor; under the condition that the actual rotating speed of the engine exceeds the idle speed value, the starting torque is switched to the motor control torque according to the slope limiting data, so that the motor demand torque is obtained; and generating a speed regulation instruction according to the engine demand torque and the motor demand torque, wherein the speed regulation instruction is used for controlling the speed regulation of the engine. The defects that in the prior art, the rotating speed of an engine is overshoot, a headstock is prone to shaking, and the speed adjusting time of the engine is short are overcome.

    本发明涉及发动机控制技术领域,提供一种基于驻车充电的发动机调速方法、驻车充电方法和装置,其中的方法包括:获取发动机的实际转速,并计算所述实际转速与预存的目标转速之间的转速差;根据所述转速差计算发动机需求扭矩和电机控制扭矩;获取电机实际扭矩和启动扭矩,根据所述电机实际扭矩获得斜率限制数据;在所述发动机的实际转速超过怠速值的情况下,根据所述斜率限制数据将所述启动扭矩切换至所述电机控制扭矩,以获得电机需求扭矩;根据所述发动机需求扭矩和所述电机需求扭矩生成调速指令,所述调速指令用于控制所述发动机调速。解决了现有技术中发动机转速超调,容易发生车头抖动,以及发动机调速时间慢的缺陷。
