Abstract
A steering control device controls a turning motor that generates a turning force for causing turning wheels of which power transmission to and from a steering wheel is cut off to turn. The steering control device includes a first processor configured to change a steering angle ratio which is a ratio of a turning angle of the turning wheels to a steering angle of the steering wheel according to a vehicle speed through control of the turning motor and a second processor configured to change a degree of change of the steering angle ratio with respect to change of the vehicle speed according to a steering state or a vehicle state.
Claims13
A steering control device comprising a controller configured to:
- control a turning motor that generates a turning force for causing turning wheels, of which power transmission to and from a steering wheel is cut off, to turn;
- change a steering angle ratio according to a vehicle speed through control of the turning motor, wherein the steering angle ratio is a ratio of a turning angle of the turning wheels to a steering angle of the steering wheel;
- and
- change, when the steering wheel is being held at a constant steering angle with respect to a neutral position or when the vehicle is turning, a degree of change of the steering angle ratio with respect to the vehicle speed due to acceleration or deceleration of the vehicle.
