The invention relates to the technical field of electric automobiles, in particular to an electric automobile torque control method and system and a readable storage medium. The torque control method for the electric vehicle comprises the steps that motion state information of the vehicle is obtained in real time in the motion process of the vehicle; updating the improved vehicle lateral dynamics control equation in real time according to the motion state information; and the updated vehicle lateral dynamic control equation is adopted to control torque distribution of the vehicle. According to the vehicle lateral dynamic control method and system, network communication delay among all systems of the vehicle is considered, a new vehicle lateral dynamic control equation is redesigned, all delay factors in a vehicle control system are considered in the vehicle lateral dynamic control equation, and then the new vehicle lateral dynamic control equation is adopted to control torque distribution of the vehicle; the influence of time delay on a control system is reduced, and the vehicle control precision and stability are improved.

    本发明涉及电动汽车技术领域,具体涉及一种电动汽车力矩控制方法和系统以及可读存储介质。本申请的电动汽车力矩控制方法包括:在车辆运动过程中实时获取车辆的运动状态信息;根据运动状态信息实时更新改进后的车辆侧向动力学控制方程;采用更新后的车辆侧向动力学控制方程控制车辆的力矩分配。本申请考虑到车辆各系统之间网络通信的延时,重新设计了新的车辆侧向动力学控制方程,该车辆侧向动力学控制方程中考虑到了车辆控制系统中的各个延时因素,然后采用新的车辆侧向动力学控制方程控制车辆的力矩分配,降低了延时对控制系统的影响,提高了车辆控制精度和稳定性。
