Provided is a steering device (100) which holds a steering member (200) such that the steering member (200) can be moved between an advanced position at which a driver can carry out steering and a retracted position on a vehicle front side. The steering device (100) comprises a fixed member (110) mounted to a vehicle body, a movable member (120) to which a steering shaft body (150) for holding the steering member (200) is rotatably attached, and an upper-side guide mechanism (130) and a lower-side guide mechanism (140) which linearly guide the movable member (120) with respect to the fixed member (110). The position of the end portion of the upper-side guide mechanism (130) on the advanced side in the advanced-retracted direction of the movable member (120) is arranged on the advanced side with respect to the position of the end portion of the lower-side guide mechanism (140) on the advanced side.
Provided is steering torque control processing (M26) including processing of using a proportional element (M50) and a differential element (M60) corresponding to a difference between a steering torque and a target steering torque to calculate an operation amount for controlling the steering torque to achieve the target steering torque. An extension phase controller is provided to at least one element of two of the proportional element and the differential element. Extension phase controllers (M54, M66) are controllers each of which extend the advancement of the phase of the differential element with respect to the phase of the proportional element.
This steering control device is configured to perform torque feedback processes (M40, M62, M72, M74, M80), an operation process (M30), and characteristic changing processes (M64, M66, M76, M78). The torque feedback processes include a process for calculating an operation amount for controlling a steering torque to a target steering torque through feedback control. The operation process is for operating a drive circuit of a motor on the basis of the operation amount. The characteristic changing processes are for changing response characteristics of the feedback control in accordance with the operation state of an operation member.
The present invention is configured to execute torque feedback processing (M40), operation processing (M42), and a characteristic change processing (M60, M74, M86). The torque feedback processing includes processing of calculating the operation amount for applying feedback control to a steering torque to attain a target steering torque. The steering torque is a torque input to an operation member. The operation processing is processing of operating a drive circuit for a motor on the basis of the operation amount. The characteristic change processing is processing of changing a response characteristic of the feedback control according to the magnitude of the torque of the motor.
