The invention relates to the technical field of electric automobiles, and discloses a driving torque adjusting method, device and equipment and a storage medium, and the method comprises the following steps: in the vehicle running process, determining a target driving torque for inhibiting the slipping of a driving wheel according to the slip rate of the driving wheel; determining a target yaw velocity of the vehicle based on the driving parameters of the vehicle; a target driving torque difference value between the outer side actual driving torque of the steering outer side driving wheel and the inner side actual driving torque of the steering inner side driving wheel is determined through the target yaw velocity; and when the vehicle is in the slipping state, the actual driving torque of the steering outer side driving wheel and the actual driving torque of the steering inner side driving wheel are adjusted according to the target driving torque and the target driving torque difference value. When the vehicle is in the slipping state, the actual driving torque of the steering outer side driving wheel and the actual driving torque of the steering inner side driving wheel are adjusted through the target driving torque, slipping of the driving wheels of the vehicle is stably restrained, and the driving experience of a user is effectively improved.

    本发明涉及电动汽车技术领域,公开了一种驱动扭矩调节方法、装置、设备及存储介质,该方法包括:在车辆行驶过程中,根据驱动轮的滑移率确定抑制驱动轮打滑的目标驱动扭矩;基于车辆的行驶参数确定车辆的目标横摆角速度;通过目标横摆角速度确定转向外侧驱动轮的外侧实际驱动扭矩与转向内侧驱动轮的内侧实际驱动扭矩之间的目标驱动扭矩差值;在车辆处于打滑状态时,根据目标驱动扭矩和目标驱动扭矩差值分别调节转向外侧驱动轮和转向内侧驱动轮的实际驱动扭矩。本发明在车辆处于打滑状态时,通过目标驱动扭矩分别调节转向外侧驱动轮和转向内侧驱动轮的实际驱动扭矩,实现了稳定抑制车辆的驱动轮打滑,有效提高了用户的驾驶体验。
