The invention provides a torque distribution method, a vehicle and a computer readable storage medium. The method comprises the steps that the left wheel yawing torque and the right wheel yawing torque of the vehicle and the left motor request torque and the right motor request torque controlled based on the slip rate are obtained; determining a left motor target torque according to the left wheel yaw moment and the left motor request torque, and determining a right motor target torque according to the right wheel yaw moment and the right motor request torque; distributing torque to the left motor according to the left motor target torque, and distributing torque to the right motor according to the right motor target torque. Limiting factors such as a vehicle body electronic stability control system, the slip rate, the available torque and power of the motors and the influence on torque distribution are comprehensively considered, the torque of the left and right motors is distributed more reasonably and accurately based on the factors, it is guaranteed that the left and right motors of the vehicle can operate efficiently, the torque is fully utilized, and the service life of the vehicle is prolonged. Therefore, the dynamic property and the stability of the vehicle are improved.
本发明提出一种扭矩分配方法、车辆和计算机可读存储介质,该方法包括:获取车辆的左轮横摆力矩、右轮横摆力矩及基于滑移率控制后的左电机请求扭矩和右电机请求扭矩;根据左轮横摆力矩和左电机请求扭矩确定左电机目标扭矩,根据右轮横摆力矩和右电机请求扭矩确定右电机目标扭矩;根据左电机目标扭矩对左电机分配扭矩,根据右电机目标扭矩对右电机分配扭矩。本发明综合考虑了车身电子稳定控制系统、滑移率、电机可用扭矩和功率等限制因素及对扭矩分配的影响,基于这些因素对左右电机的扭矩进行更加合理和精准的分配,保证车辆的左右电机能够高效运行,充分利用扭矩,从而提高车辆的动力性和稳定性。
