ABSTRACT:
When a driver voluntarily operates the steering during an automatic steering control operation, the automatic steering control operation is discontinued and a normal power steering control operation is resumed. The automatic steering control operation is not quickly changed to power steering control operation, but rather is gradually changed to the power steering control operation, to prevent a sudden change in the steering reaction which the driver receives from the steering wheel and, hence, to decrease the feeling of incompatibility. While the control amount of a steering actuator changes accompanying the change of the operation from the mode of automatic steering control operation to the mode of power steering control operation, the control amount is linearly changed from a value of the automatic steering control operation to a value of the power steering control operation over a predetermined period of time.
