Abstract
A control apparatus comprises a target steering angle operation unit for operating target steering angles of front wheels and rear wheels, a steering increase/steering return determination unit for determining as to whether steering wheel manipulation is in an increasing state or in a return state, a target rotation center azimuth operation unit for operating a target rotation center azimuth so that a rotation center azimuth &thgr; is decreased in a case of steering increase and a rotation center azimuth &thgr; is increased in a case of steering return, a vehicle behavior estimation unit for estimating a vehicle behavior based on the target rotation center azimuth, a corrected target rotation center azimuth operation unit for operating a corrected target rotation center azimuth so that the vehicle behavior does not exceed a specified value, and a corrected target steering angle operation unit for operating a corrected target steering angle realizing the corrected target rotation center azimuth.
