The invention relates to a vehicle steering torque control method and system. The vehicle steering torque control method comprises the steps that the currently requested steering torque X is received; acquiring the current speed V of the vehicle; identifying a current assistance mode of the vehicle; wherein the current power assisting modes at least comprise two different modes; according to the current power assisting mode and the current vehicle speed V, a preset power assisting function corresponding to the current vehicle speed in the current power assisting mode is obtained; correcting the steering torque X according to the current vehicle speed V to obtain corrected steering torque X correction; performing correction calculation according to the power-assisted function and the steering torque X to obtain a motor execution torque; and vehicle steering is controlled according to the motor execution torque. By means of the method and device, the problem that in the lane keeping auxiliary function control process in different power-assisted steering modes, the steering torque request performance of the EPS executing the ADAS is inconsistent can be effectively solved.

    本发明涉及一种车辆转向扭矩控制方法与系统,包括:接收当前请求的转向扭矩X;获取车辆的当前车速V;识别车辆的当前助力模式;其中所述当前助力模式至少包括两种不同模式;根据所述当前助力模式以及所述当前车速V获得在当前助力模式下,与所述当前车速对应的预先设置的助力函数;根据所述当前车速V对所述转向扭矩X进行修正得到修正后的转向扭矩X修正;根据所述助力函数和所述转向扭矩X修正计算得到电机执行扭矩;根据所述电机执行扭矩控制车辆转向。通过本发明,可以有效解决不同转向助力模式下车道保持辅助功能控制过程,EPS执行ADAS的转向扭矩请求性能不一致的问题。
