Abstract
In a steering control device, a road surface reaction force torque calculation module (52) uses a vehicle speed, steering angle, and vehicle model to calculate a caster-trail-caused torque, a self-aligning torque, and a road surface reaction force torque. A reaction force command current calculation module (53) uses the road surface reaction force torque and the vehicle speed to calculate a reaction force command current.
