The invention discloses a target torque determination method and device, a vehicle and a storage medium, and belongs to the technical field of vehicles. According to the technical scheme provided by the embodiment of the invention, the yaw torque modes of the plurality of driving motors of the target vehicle are determined in response to the slip torque intervention signal and the torque overrun signal of the target vehicle. And determining the yaw torque deviation of the target vehicle in the yaw torque mode based on the request torques of the plurality of driving motors and a second torque, and the second torque is obtained after the first torque is limited by the torque threshold value. And determining a first target torque of each driving motor based on the yaw torque deviation and the yaw torque tolerance of the target vehicle. And each driving motor is controlled based on the first target torque of each driving motor, so that accurate control of the target vehicle is realized, the stability of the target vehicle is improved, and the safety of the electric vehicle is improved.

    本申请公开了一种目标扭矩的确定方法、装置、车辆和存储介质,属于车辆技术领域。通过本申请实施例提供的技术方案,响应于目标车辆的滑移扭矩干预信号和扭矩超限信号,确定该目标车辆的多个驱动电机的偏航扭矩模式。基于该多个驱动电机的请求扭矩和第二扭矩,确定该偏航扭矩模式下该目标车辆的偏航扭矩偏差,该第二扭矩是该第一扭矩经过该扭矩阈值限制后得到的。基于该目标车辆的偏航扭矩偏差与偏航扭矩公差,确定各个驱动电机的第一目标扭矩。控制基于各个驱动电机的第一目标扭矩来控制各个驱动电机,实现对目标车辆的精准控制,提高目标车辆的稳定性,提高电动车辆的安全性。
