Abstract
A steering control device is configured to execute a torque control process, a feedback amount calculation process, and an automatic control calculation process. The torque control process is a process of controlling torque of the motor according to a value of a required torque variable. The required torque variable is a variable that indicates a target value for the torque of the motor. The feedback amount calculation process is a process of calculating a value of the required torque variable in order to control steering torque to target steering torque through feedback control.
Claims15
A steering control device configured to operate a motor mechanically coupled to an operation member that is operated by a driver to steer a vehicle, wherein:
