Abstract
In the event that the differential value of the target node deviation is equal to or greater than a deviation threshold, and the absolute value of the steering torque is equal to or greater than a steering torque threshold, the system outputs signals to a brake control device such that deceleration of the vehicle is made with a predetermined deceleration, and outputs signals to an electric power steering control device so as to cancel automatic steering, whereby the system enters a normal power steering mode, and the automatic driving mode is canceled. Thus, abnormal situations are precisely detected during automatic driving, giving consideration to the control error and the intent of the user, thereby enabling driving control matching the intent of the user.
