ABSTRACT:
In a steering angle correcting system, a steering amount required to maintain a positional relationship of a subject vehicle to a road lane ahead of the subject vehicle is calculated in a steering amount calculating device based on outputs from a first detecting device for detecting the state of a lane of a road ahead of the vehicle or which the vehicle is traveling, and a second detecting device for detecting a current positional relationship of the subject vehicle to the road lane. A steering device is driven by a driving device mounted between a grasping portion of a steering wheel and the steering device so as to decrease the difference between a steering amount detected by a steering amount detecting device and a steering amount calculated in the steering amount calculating device. Whenever a driver's intention and the determination by the system are different from each other, a driver can operate the steering wheel to intervene in the steering. In addition, the driver can immediately intervene in the steering at all times, while normally maintaining a cooperating relationship with the system. Thus, the steering angle correcting system has a semi-automatic steering concept.
