The invention relates to an electric vehicle driving control method and device, computer equipment and a storage medium. The method comprises the steps that the attachment states of front axle wheels and rear axle wheels are determined; when the attachment states of the front axle wheels and the rear axle wheels are both stable states, correction parameters are determined from a preset first mapping relation according to the vehicle speed, the steering wheel turning angle and the vehicle body yaw velocity of the vehicle, and when the correction parameters are smaller than a first threshold value, it is determined that the rear axle of the vehicle is a driving axle; when the correction parameter is larger than or equal to the first threshold value, it is determined that a front axle and a rear axle of the vehicle are both driving axles, a first transfer proportion of the front axle is determined from a preset second mapping relation according to the correction parameter, the required torque is transferred to the front axle according to the first transfer proportion, and the required torque is transferred to the rear axle according to the second transfer proportion; by the adoption of the method, the problem that in the prior art, torque distribution of the electric vehicle cannot be flexibly controlled is solved.
本申请涉及一种电动汽车驱动控制方法、装置、计算机设备和存储介质,所述方法包括确定前轴车轮和后轴车轮的附着状态;当前轴车轮和后轴车轮的所述附着状态均为稳定状态时,根据车辆的车速、方向盘转角以及车身横摆角速度,从预设的第一映射关系中确定修正参数,当修正参数小于第一阈值时,确定车辆的后轴为驱动轴;当所述修正参数大于或等于所述第一阈值时,确定车辆的前轴和后轴均为驱动轴,并根据所述修正参数,从预设的第二映射关系中确定前轴的第一转移比例,将所述需求扭矩根据所述第一转移比例向前轴转移,以从后驱控制切换为四驱控制,采用本申请的方法,改善现有技术中电动汽车扭矩分配无法灵活控制的问题。
