The invention provides a range extender start and stop control method and system, terminal equipment and a storage medium, and the method comprises the following steps: obtaining a stop position of a piston after a stop signal of a range extender is received; when it is judged that the stopping position is located in the avoiding area, the stopping torque of the crankshaft is obtained; the avoiding area is an area in the air cylinder and meets the condition that when the piston is started in the avoiding area, the knocking sound rate of the range extender is larger than or equal to a first preset threshold value; according to the scheme, on the basis of the shutdown torque, the dragging torque corresponding to the shutdown torque is obtained through calculation, the crankshaft is driven to output the dragging torque, the piston is dragged out of the avoiding area for next starting of the range extender, on the basis that the arrangement space in the vehicle is not occupied, the method which is simple, easy to implement and high in operability is provided, the NVH (Noise, Vibratation and Harshness) problems are solved, and the application range of the range extender is widened. And the driving experience is improved.

    本申请提供一种增程器启停的控制方法、系统、终端设备及存储介质,该方法包括以下步骤:接收到增程器停机信号后,获取活塞的停运位置;判断停运位置位于规避区内时,获取曲轴的停机扭矩;规避区为气缸内的区域,其满足:当活塞在规避区内启运时,增程器的敲击声率大于或等于第一预设阈值;基于停机扭矩,计算得到该停机扭矩对应的拖拽扭矩,并驱动曲轴输出拖拽扭矩,将活塞拖拽出规避区,以待下次增程器的启动,该方案在不挤占车内布置空间的基础上,提供简单易行、可操作性强的方法解决了NVH(噪声Noise、振动Vibration与声振粗糙度Harshness)问题,提升驾乘体验。
