Abstract:
Although the steering angle control of a steering wheel is performed using automatic steering control, when the steering torque is applied by the steering wheel operation of the driver, the target steering angle is corrected to become the same direction as a direction that the steering torque is applied, and the steering angle control is performed to coincide with that target steering angle. Thereby, in the case of adding together outputs of the steering angle control with respect to the corrected target steering angle and the assist control by the steering torque with a certain ratio, it is possible to make the output direction of the automatic steering control coincide with the output direction of the manual steering control, and the control outputs become hard to interfere with each other. As a result, the uncomfortable feeling given to the driver that occurs in switching the steering mode is reduced.
