The invention belongs to the technical field of automobiles, and particularly discloses an automobile steering torque control method which comprises the following steps: acquiring a vehicle state, and acquiring a steering wheel steering angular rate, a steering wheel steering angle, a vehicle speed and a conventional required torque of a vehicle when determining that the vehicle is in a preset steering working condition based on the vehicle state, according to the steering angle of the steering wheel and the vehicle speed, first correction is carried out on the conventional demand torque to obtain first correction torque, according to the steering angle rate of the steering wheel and the vehicle speed, second correction is carried out on the conventional demand torque to obtain second correction torque, and based on the first correction torque and the second correction torque, the first correction torque and the second correction torque are obtained. And when the third correction torque is within the preset safety torque range, the third correction torque is optimized according to the preset comfort constraint condition, and the steering control correction torque is obtained, so that the vehicle steers based on the steering control correction torque. According to the method, the steering angle and the steering angle rate of the steering wheel are dynamically recognized in real time, the torque is accurately corrected according to the vehicle speed, the stability of the vehicle in the steering process can be remarkably improved, the dynamic adjustment can ensure that the vehicle can keep a stable driving state at various speeds and steering angles, and the driving stability of the vehicle is improved. Therefore, the driving safety and comfort are improved.
