Patent ID: 8340871

Claim:
A vehicle steering control device: wherein a steering wheel is mechanically disconnected from a turning mechanism for turning a steering road-wheel; configured to perform a normal control for controlling a turning angle of the steering road-wheel on the basis of a first target turning angle set according to a steering angle of the steering wheel; configured to perform an automatic turning control for controlling the turning angle of the steering road-wheel irrespective of a driver's manipulation of the steering wheel on the basis of a second target turning angle set according to a running state of a vehicle; and wherein the vehicle steering control device comprises a reaction-force control section configured to control a steering reaction force to be applied to the steering wheel, by defining a value of the steering angle at which the steering reaction force is equal to 0, as a value of the steering angle at a time of straight running of the vehicle, under the normal control, and to control the steering reaction force, by defining a value of the steering angle set according to the second target turning angle, as the value of the steering angle at which the steering reaction force is equal to 0, under the automatic turning control.
