The present application relates to a method and a system for controlling vehicle steering torque, includes: receiving a steering torque X currently requested; obtaining a current vehicle velocity V of the vehicle; identifying a current assistance mode of the vehicle, wherein the current assistance mode at least includes two different modes; obtaining a preset auxiliary function corresponding to the current vehicle velocity in the current assistance mode according to the current assistance mode and the current vehicle velocity V; and correcting the steering torque X according to the torque correction gain to obtain a corrected steering torque Xcorrected; obtaining a motor execution torque by calculating the auxiliary function and the corrected steering torque Xcorrected; controlling the vehicle to change direction according to the motor execution torque. The present application can effectively solve the problem of inconsistency in the steering torque request performance of the EPS executing ADAS in the lane keeping auxiliary function control process under different steering assistance modes.
