Claim:
1. A steering control device, comprising: an actuator for applying a steering assist torque to a steering system of a vehicle; a steering torque detection section for detecting a steering torque acting on the steering system of the vehicle; a steering angle detection section for detecting a steering angle of the steering system of the vehicle; a steering assist torque calculation section for calculating a steering assist torque to be applied to the actuator in order to improve return characteristics of the steering system; a steering state determination section for determining a steering state of a driver; a steering assist torque correction section for correcting the steering assist torque depending on a steering state determination result of the steering state determination section; and an actuator control section for controlling the actuator depending on the corrected steering assist torque, wherein the steering state determination section determines the steering state of the driver based on at least the steering torque, the steering angle, and a vehicle speed, and on a combination of at least two of the following: wherein the actuator control section drives the actuator depending on the steering assist torque that is corrected by the steering assist torque correction section based on the determination result of the steering state of the driver.
