VEHICLE STEERING SYSTEM AND VEHICLE STEERING METHOD

摘要

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.

1. 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.
