The invention relates to the technical field of hybrid vehicles, and particularly discloses a hybrid vehicle motor overspeed control method and device, a hybrid vehicle and a storage medium. According to the hybrid vehicle motor overspeed control method, the actual rotating speed of a motor is obtained, the actual rotating speed is compared with a preset rotating speed, and when na * the preset rotating speed is larger than or equal to the actual rotating speed and smaller than the preset rotating speed, the motor overspeed is controlled. The actual opening degree of an accelerator and the slope where the hybrid vehicle is located are obtained, the subjective intervention degree of a driver is determined based on the actual opening degree of the accelerator and the slope where the hybrid vehicle is located, the adjusting coefficient is determined based on the subjective intervention degree of the driver, and the target demand torque is determined based on the actual opening degree of the accelerator; the target demand torque is adjusted based on the adjustment coefficient, the actual demand torque is obtained, the engine and/or the motor are controlled to output the actual demand torque, when the actual rotating speed of the motor is close to overspeed, the current subjective driving intention of a driver is fully considered, and motor safety and driving environment safety are both considered.

    本发明涉及混动车辆技术领域,具体公开了一种混动车辆电机超速控制方法、装置、混动车辆及存储介质,该混动车辆电机超速控制方法通过获取电机的实际转速,比较实际转速与预设转速的大小,当na*预设转速≤实际转速<预设转速时,获取油门的实际开度以及混动车辆所处的坡度,基于油门的实际开度和混动车辆所处的坡度确定驾驶员的主观介入度,基于驾驶员的主观介入度确定调节系数,基于油门的实际开度确定目标需求扭矩,基于调节系数对目标需求扭矩进行调节并得到实际需求扭矩,控制发动机和/或电机输出实际需求扭矩,在电机的实际转速临近超速时,充分考虑的驾驶员当前的主观驾驶意愿,兼顾了电机安全和行车环境安全。
