Abstract
In a vehicle steering that sets a target steering reaction force to be applied to a steering wheel on the basis of a steering angle of the steering wheel and that applies the target steering reaction force to the steering wheel; the target steering reaction force is set so that the target steering reaction force changes on the basis of whether a steering mode of the steering wheel is turn steering in which the absolute value of a steered angle of a steered wheel is increased or return steering in which the absolute value of the steered angle is reduced; and the set target steering reaction force is applied to the steering wheel.
Claims10
A vehicle steering system, comprising:
- an electronic control unit configured to:
- i) set a target steering reaction force to be applied to a steering wheel on the basis of a steering angle of the steering wheel,
- ii) set the target steering reaction force on the basis of a degree of turn steering and a degree of return steering, the turn steering and the return steering being steering modes of the steering wheel, an absolute value of a steered angle of a steered wheel being increased in the turn steering, and the absolute value of the steered angle being reduced in the return steering, and
- (iii) apply the target steering reaction force set by the electronic control unit to the steering wheel.
A steering method for a vehicle including an electronic control unit, comprising:
- setting, by the electronic control unit, a target steering reaction force to be applied to a steering wheel on the basis of a steering angle of the steering wheel;
- setting, by the electronic control unit, the target steering reaction force on the basis of a degree of turn steering and a degree of return steering, the turn steering and the return steering being steering modes of the steering wheel, an absolute value of a steered angle of a steered wheel being increased in the turn steering, and the absolute value of the steered angle being reduced in the return steering;
- and
- applying, by the electronic control unit, the set target steering reaction force to the steering wheel.
