  • Publication number: 20190233000
    Abstract: A steering control device which can suppress a degradation in the steering feel caused when a steering wheel is moved back from a steering limit is provided. A steering control device controls a steer-by-wire steering system that includes a steering-side motor that generates a steering reaction force to be applied to a steering wheel to control operation of the steering-side motor. The steering control device includes an angular speed control circuit that performs feedback control on the steering-side motor in the case where a steering angle of the steering wheel reaches a virtual rack end and the steering wheel is steered back toward the steering neutral. The feedback control is performed such that a steering speed computed on the basis of the steering angle coincides with a target steering speed that is the target value for the steering speed and that is set in accordance with the steering angle.

  • Publication number: 20190233001
    Abstract: A steering control device with reduced power consumption is provided. In the case where an IG signal is turned on, a CPU disengages a clutch, and operates torque of a steered-side motor in order to control the steered angle of steered wheels to a target steered angle that matches an operation on the steering wheel through feedback control. The CPU decreases a current that flows through the steered-side motor with respect to a request by feedback control in the case where the logical product of a statement that a vehicle speed is equal to or less than a prescribed speed, a statement that the absolute value of steering torque which is input torque input to the steering wheel is equal to or less than a prescribed value, and a statement that the absolute value of a steering speed is equal to or less than a predetermined speed.
