PROBLEM TO BE SOLVED: To reduce behavior changes of a vehicle, to improve travel performance of the vehicle and to make a driver feel less odd by controlling the steering angle of a steered wheel to reduce influence imparted on the vehicle by a toe change of a wheel by roll steering. SOLUTION: A target steering angleδft of a front wheel is calculated to attain a prescribed steering characteristic (S320). Change amountΔδf of the steering angle of the front wheel and change amountΔδr of the steering angle of a rear wheel caused by the roll steering are calculated (S330, 335, 340, 345). Based on the change amountΔδf andΔδr of the steering angle, target correction amountΔδft of the steering angle of the front wheel is calculated to cancel a change of a yaw rateγof the vehicle caused by the toe change of the wheel by the roll steering (S350). The target steering angleδft of the front wheel is corrected to be the sum of the target steering angleδft of the front wheel and the correction amountΔδft of the steering angle of the front wheel (S360). A turning angle variable device 34 is controlled so that the steering angleδf of the front wheel may be the target steering angleδft (S370, 380). COPYRIGHT: (C)2008,JPO&INPIT |
