<p>PROBLEM TO BE SOLVED: To compatibly suppress the influence of an erroneous alarm on a driver and evade the state that an alarm is not issued though the alarm is required. SOLUTION: An image sensor 5 and a magnetic nail sensor 6 are used for recognizing a traveling path. By the difference of the values of the side shift of a vehicle by both sensors, the reliability of traveling path recognition is judged (32). Also, when it is judged that the vehicle deviates from a lane (33), the driver is alarmed by vibration torque application (34) and return torque application (35), and the alarm is changed corresponding to the reliability of the traveling path recognition.</p> |
