The invention provides a vehicle speed determination method and device, a vehicle and a storage medium, and belongs to the technical field of automobiles. The method comprises the steps that the driving state of the vehicle is determined according to the brake pedal flag position of the vehicle and the total torque of the vehicle; determining driving conditions of a plurality of wheels, wherein the driving conditions of the wheels are used for representing whether the wheels slip or not; if the driving conditions of the plurality of wheels indicate that at least one non-slip wheel exists, determining a target wheel speed from the wheel speeds of the at least one non-slip wheel according to the driving state; and determining the speed of the vehicle according to the target wheel speed. The optimal target wheel speed meeting the current driving state is determined from the non-slipping wheels, so that the speed of the vehicle is determined according to the target wheel speed, the influence of vehicle slipping on vehicle speed determination is prevented, and the accuracy of vehicle speed determination is improved. The target wheel speed is selected in combination with the driving state of the vehicle, the wheel speed at the critical value in the current driving state is prevented from being selected, and the accuracy of determining the wheel speed is further improved.

    本申请提供了一种车速确定方法、装置、车辆和存储介质,属于汽车技术领域,该方法包括:根据车辆的制动踏板标志位和车辆的总扭矩,确定车辆的行驶状态;确定多个车轮的行驶工况,车轮的行驶工况用于表示车轮是否打滑;若多个车轮的行驶工况表示存在至少一个未打滑的车轮,根据行驶状态,从至少一个未打滑的车轮的轮速中,确定目标轮速;根据目标轮速,确定车辆的车速。通过从未打滑的车轮中,确定满足当前行驶状态的最佳目标轮速,从而根据该目标轮速确定车辆的速度,这样防止了车辆打滑对车速确定的影响,提高了确定车速的准确性。结合车辆的行驶状态选择目标轮速,防止选择到当前行驶状态下处于临界值的轮速,进一步提高了确定轮速的准确性。
