The invention discloses a vehicle energy recovery method and device and a computer readable storage medium. The method relates to the field of intelligent automobiles and comprises the steps that in response to a received braking instruction, the torque required by a driver is determined based on the braking instruction; processing the driver demand torque by using a five-section slope filtering algorithm to obtain a target demand torque; the sum of the braking recovery demand torque sent by a vehicle body stability controller in the vehicle and the target demand torque is obtained, and the total demand torque is obtained; and controlling an electric machine in the vehicle based on the total demand torque. The technical problem that the driving comfort is poor due to the fact that the vehicle shakes under the condition that the driving working condition and the braking working condition of the vehicle are switched is solved.

    本发明公开了一种车辆能量回收方法、装置及计算机可读存储介质。其中,该方法涉及智能汽车领域,该方法包括:响应于接收到制动指令,基于所述制动指令确定驾驶员需求扭矩;利用五段式斜率滤波算法对所述驾驶员需求扭矩进行处理,得到目标需求扭矩;获取车辆中的车身稳定控制器发送的制动回收需求扭矩与所述目标需求扭矩之和,得到总需求扭矩;基于所述总需求扭矩控制所述车辆中的电机。本发明解决了车辆在驱动和制动工况切换的情况下车辆发生抖动导致驾驶舒适度较差的技术问题。
