Abstract
A steering control device is configured to execute torque feedback processing, operation processing, and characteristics changing processing. The torque feedback processing includes processing of calculating a manipulated variable for controlling a steering torque to a target steering torque by feedback control, the operation processing is processing of operating a drive circuit of a motor based on the manipulated variable, and the characteristics changing processing is processing of changing response characteristics of the feedback control in accordance with an operation state of an operating member.
Claims16
A steering control device configured to operate a motor mechanically linked to an operating member that is operated by a driver to steer a vehicle, wherein:
- the steering control device is configured to execute torque feedback processing, operation processing, and characteristics changing processing;
- the torque feedback processing includes processing of calculating a manipulated variable for controlling a steering torque to a target steering torque by feedback control;
- the steering torque is torque input to the operating member;
- the operation processing is processing of operating a drive circuit of the motor based on the manipulated variable, in a state in which the operating member and steered wheels of the vehicle are mechanically disconnected from each other;
- and
- the characteristics changing processing is processing of changing response characteristics of the feedback control in accordance with an operation state of the operating member.
