The invention provides a slip rate determination method and device, a vehicle and a storage medium, and belongs to the technical field of automobiles, the method comprises the steps that when the variable quantity of the acceleration of a whole vehicle exceeds a preset threshold value, latest activation flag bits of a plurality of slip control modules are obtained, and the latest activation flag bits are activation flag bits of the slip control modules at the current moment; determining a target attachment coefficient according to the plurality of latest activation flag bits and historical activation flag bits of the plurality of slip control modules, the historical activation flag bits being the activation flag bits of the slip control modules at the last moment; and determining the slip rate of the current vehicle according to the target adhesion coefficient. According to the scheme, when the target slip rate is determined, the slip rate is further determined in combination with the slip control module of the vehicle, and the accuracy of determining the slip rate is improved.

    本申请提供了一种滑移率确定方法、装置、车辆和存储介质,属于汽车技术领域,该方法包括:当整车加速度的变化量超过预设阈值时,获取多个滑移控制模块的最新激活标志位,最新激活标志位为滑移控制模块在当前时刻的激活标志位;根据多个最新激活标志位与多个滑移控制模块的历史激活标志位,确定目标附着系数,历史激活标志位为滑移控制模块在上一时刻的激活标志位;根据目标附着系数,确定当前车辆的滑移率。通过本方案,在确定目标滑移率时,结合车辆的滑移控制模块进一步确定滑移率,提高了确定滑移率的准确性。
