The invention relates to an electric vehicle control method and device, a storage medium and electronic equipment, by distributing the output torque of a vehicle motor, it is prevented that the motor is overheated due to stalling, damage to related parts on a vehicle is caused, and the technical problems that the vehicle is seriously impacted and generates abnormal sound, and the driving intention cannot be achieved are solved. The method comprises the steps that when the electric vehicle is in an obstacle crossing working condition, a target motor is determined from all motors of the electric vehicle; the temperature of a power electronic device used for controlling the target motor is obtained, and a target torque limit value is determined according to the temperature and the preset corresponding relation between the temperature of the power electronic device and the torque limit value corresponding to the target motor; and the required torque of the electric vehicle is preferentially distributed to the target motor under the condition that the target torque limit value is not exceeded.
本公开涉及一种电动车辆控制方法、装置、存储介质及电子设备,通过对车辆电机的输出扭矩进行分配,防止电机因堵转发生过热,造成车辆上相关零部件的损坏,避免车辆出现严重冲击和异响,以及无法实现驾驶意图的技术问题。该方法包括:在所述电动车辆处于越障工况下,从所述电动车辆的各电机中确定目标电机;获取用于控制所述目标电机的电力电子器件的温度,并根据所述温度,以及所述电力电子器件的温度与对应所述目标电机的扭矩限值之间预设的对应关系,确定目标扭矩限值;在不超过所述目标扭矩限值的情况下,将所述电动车辆的需求扭矩优先分配给所述目标电机。
