The invention relates to a method and device for adjusting the rotating speed of an engine through an ISG motor, a medium and a vehicle. The method comprises the steps that current working condition information of the engine of the hybrid vehicle is obtained; PI parameters are determined according to the current working condition information; and the ISG motor is driven according to the determined PI parameters and a preset PI control algorithm so as to adjust the rotating speed of the engine. According to the technical scheme, the rotating speed of the ISG motor is controlled and adjusted according to the PI control algorithm. The PI parameters in the algorithm are determined according to the real-time working condition of the engine, different PI parameters can be applied to control and adjust the rotating speed of the ISG motor under different working conditions, and then the rotating speed of the engine is adjusted, so that the speed regulation of the engine has short speed regulation time and high speed regulation precision under different working conditions, the speed regulation performance of the engine under various working conditions is improved, and the method is reliable and good in practicability.

    本公开涉及一种使用ISG电机调节发动机转速的方法和装置、介质、车辆。该方法包括:获取混合动力车辆的发动机的当前工况信息;根据当前工况信息确定PI参数;根据所确定的PI参数和预定的PI控制算法,驱动ISG电机,以调节发动机的转速。通过上述技术方案,根据PI控制算法来控制调节ISG电机的转速。其中,算法中的PI参数根据发动机的实时工况来确定,不同的工况下,可以应用不同的PI参数来控制调节ISG电机转速,进而调节发动机转速,使得在不同的工况下,发动机调速都具有较短的调速时间和较高的调速精度,提升了各工况下的发动机调速性能,方法可靠且实用性好。
