VEHICLE STEERING CONTROL APPARATUS
First Claim
1. A vehicle steering control apparatus comprising:
- a first calculating device for calculating a basic assist steering force to assist a steering operation on the basis of at least one of an steering angle and steering torque corresponding to the steering operation by a person in a vehicle;
an obtaining device for obtaining a lateral force of each of the front wheels and rear wheels;
a second calculating device for both calculating a first correction steering force which reduces the basic assist steering force on the basis of the lateral force of the rear wheels and calculating a second correction steering force which increases the basic assist steering force on the basis of the lateral force of the front wheels; and
a steering force applying device for applying, to the vehicle, a target assist steering force obtained by adding both the first correction steering force and the second correction steering force to the basic assist steering force.

Abstract
A vehicle steering control device includes a first calculation mechanism calculating a basic steering assistance force based on steering torque corresponding to steering operation by an occupant of a vehicle, an acquisition mechanism acquiring respective lateral forces of front wheels and rear wheels, a second calculation mechanism calculating, based on the lateral force on the rear wheels, a first steering correction force that reduces the basic steering assistance force and also calculating, based on the lateral force on the front wheels, a second steering correction force that increases the basic steering assistance force, and a steering force application mechanism applying a target steering assistance force to the vehicle, the target steering assistance force being obtained by adding the first and second correction steering forces to the basic steering assistance force.
