To prevent a generation of a large change of a steering reaction force at the time of starting and stopping steering so as to reduce a feeling of strangeness of a driver, while controlling driven wheels with high responsivity with respect to steering. A steering control unitcontrols a steering motorbased on a final target turning angle &#x3b8;t obtained by an addition of a first target turning angle &#x3b8;and a second target turning angle &#x3b8;. A reaction force control unitcontrols a reaction force motorbased on a final target steering reaction force Tt obtained by an addition of a first target steering reaction force Tand a second target steering reaction force T. In this case, a second target steering reaction force calculation unitcalculates the second target steering reaction force Tbased on a value obtained by a variation restriction of the second target turning angle &#x3b8;based on a steering angular velocity &#x3b8;t (second turning angle correction value &#x3b8;).

Steering apparatus for vehicle

A vehicle driving operation support apparatus for a vehicle, includes a sensing section to sense a traveling condition of the vehicle including a surrounding condition inclusive of an obstacle around the vehicle, and a control section to calculate a risk potential for the vehicle in accordance with the traveling condition. The control section performs a support control to support the driver in accordance with the risk potential and performs an assist control to produce inducement simulating a condition change (such as a vehicle behavior) attributable to an increase of the risk potential, in accordance with the risk potential.

The control section further performs a cooperation control to coordinate the first assist control and the second assist control.

Vehicle driving operation support apparatus/process and cooperation control

Under an automatic turning control, a steering controller defines a value of steering angle set according to a target turning angle of the automatic turning control, as a value of steering angle at which a reaction force is equal to 0. Thereby, the steering controller controls a steering reaction force on the basis of a difference between an actual steering angle and the value of steering angle at which the reaction force is equal to 0.
