摘要： A steering control device is configured to control a steering device. The steering device includes a steering wheel, a steering shaft coupled to the steering wheel, a turning wheel of a vehicle, and a motor configured to rotate the steering shaft. The turning wheel is configured to turn along with rotation of the steering shaft. The steering control device includes a processor. The processor is configured to execute an alarm information acquisition process of acquiring information indicating that an alarm needs to be issued to a driver of the vehicle, and a vibration process of vibrating the steering wheel in a predetermined region by operating the motor, in a situation where the alarm needs to be issued. The predetermined region is a region where a turning angle of the turning wheel does not change even when the steering wheel rotates.

摘要： A steering control device controls a steering device. The steering device includes a steering shaft, a turning wheel of a vehicle, the turning wheel turning due to rotation of the steering shaft, and a motor rotating the steering shaft. The steering control device includes a processor that executes a traveling environment information acquisition process and a look-ahead compensation process. In the traveling environment information acquisition process, the processor acquires information relevant to a traveling environment of the vehicle. In the look-ahead compensation process, the processor preliminarily rotates the steering shaft depending on a play compensation amount relevant to a predetermined turn direction. The processor determines an appropriate turn direction for the vehicle, as the predetermined turn direction, from the information relevant to the traveling environment.

摘要： A steering control device includes a processor. The processor is configured to execute a target rudder angle correction process, a restriction process, and a rudder angle control process. The target rudder angle correction process is a process of correcting the value of the target rudder angle variable by a play compensation amount corresponding to a steering direction. The restriction process is a process of restricting the magnitude of the play compensation amount to a small side depending on the traveling route at a current position of the vehicle and the traveling route at a movement-directional forward position. The rudder angle control process is a process of operating the motor by a control in which a steering angle is adopted as a control amount and the value of the target rudder angle variable is adopted as a target value of the control amount.

摘要： A vehicle steering device includes: a target-steered-angle setting unit configured to set a left target steered angle that is a target value of the steered angle of a left steered wheel and a right target steered angle that is a target value of the steered angle of a right steered wheel; left motor controllers configured to control a left steering motor based on a left-steered-angle deviation that is a difference between the left steered angle and the left target steered angle; right motor controllers configured to control a right steering motor based on a right-steered-angle deviation that is a difference between the right steered angle and the right target steered angle; and an abnormality determination unit configured to determine that an abnormality has occurred when an absolute value of difference between the left-steered-angle deviation and the right-steered-angle deviation is equal to or larger than a first threshold.
