The invention discloses a kinetic energy recovery control method and device and a readable storage medium. The method comprises the steps of obtaining target torque for achieving current decelerationof a vehicle; determining the current danger level of the vehicle; querying a current value range of a kinetic energy recovery torque ratio corresponding to the current danger level in a preset kinetic energy recovery control table, wherein the kinetic energy recovery control table comprises a plurality of danger levels and a value range of a kinetic energy recovery torque ratio corresponding to each danger level, and the higher the danger level in the kinetic energy recovery control table is, the smaller the corresponding kinetic energy recovery torque ratio is; obtaining the maximum recoverable torque, which is detected by a VCU, needed by the vehicle; judging whether the ratio of the maximum recoverable torque to the target torque is within the current value range or not; and if so, converting part of the target torque into electric energy to be stored, and enabling the other part of the target torque to perform hydraulic braking, wherein the value of the torque converted into the electric energy to be stored is equal to the maximum recovery torque.

    一种动能回收控制方法、装置及可读存储介质,该方法包括:获取本车实现当前减速的目标扭矩;确定本车的当前危险等级;在预设的动能回收控制表中查询所述当前危险等级对应的动能回收扭矩占比的当前取值范围,所述动能回收控制表中包括多个危险等级和每个危险等级对应的动能回收扭矩占比的取值范围,所述动能回收控制表中危险等级越高,对应的动能回收扭矩占比越小;获取VCU检测的所述本车所需的最大可回收扭矩;判断所述最大可回收扭矩与所述目标扭矩的比值是否在所述当前取值范围内;若是,将所述目标扭矩的一部扭矩转换为电能存储,另一部分扭矩进行液压制动,其中,转换为电能存储的扭矩的值等于所述最大回收扭矩。
