The invention discloses an electric vehicle sliding energy recovery intensity control method and device and a medium, and belongs to the field of electric vehicles. The method comprises the steps: monitoring the opening degree of an accelerator pedal and the speed information of a vehicle in real time during the running of the vehicle; if the accelerator pedal opening degree is less than the accelerator pedal opening degree threshold value and the vehicle speed is greater than or equal to the minimum sliding energy recovery vehicle speed, entering a sliding energy recovery stage; detecting thedistance between the current vehicle and a front vehicle, and obtaining the deceleration required by the braking of the current vehicle based on the distance; and if the deceleration is greater thanthe preset deceleration threshold value and less than or equal to the maximum deceleration allowing sliding energy recovery, adjusting the sliding energy recovery demand torque, so that the adjusted sliding energy recovery demand torque provides the deceleration required by current vehicle braking. According to the invention, a driver can obtain the required deceleration by adjusting the opening degree of an accelerator pedal under most working conditions, the sliding energy recovery rate is improved, and the driving range of a vehicle is further improved.

    本发明公开了一种电动汽车滑行能量回收强度控制方法、装置及介质,属于电动汽车领域,其中,方法的实现包括:在车辆行进中,实时监测加速踏板开度和车速信息;若加速踏板开度低于加速踏板开度阀值,且车速大于等于最低滑行能量回收车速,则进入滑行能量回收阶段;检测当前车辆与前方车辆的距离,基于距离获取当前车辆制动所需要的减速度;若减速度大于预设减速度阈值,且小于等于允许滑行能量回收最大减速度,则调整滑行能量回收需求扭矩,以使调整后的滑行能量回收需求扭矩提供减速度为当前车辆制动所需要的减速度。通过本发明可以确保驾驶员在大部分工况下通过调节加速踏板开度获取所需减速度,提高滑行能量回收率,进一步提高车辆续驶里程。
