PURPOSE: To take safety securing action corresponding to a driver's will by providing travel road maintaining mechanism and travel road deviating action corresponding safety mechanism, and switching both mechanisms according to the specified action of the driver.
CONSTITUTION: A travel road position detecting means is formed of a camera 2, a signal processing unit 3 and an arithmetic unit 4, and an other car approaching state detecting means is formed of lateral radar head units 11, 12, a signal processing unit 13 and the arithmetic unit 4. On the basis of information from the arithmetic unit 4 and a steering angle sensor 9, a control unit 5 controls travel road maintaining mechanism, that is, a steering actuator unit 6, to actuate mechanism for performing corrected steering when there is no operation of a direction indicator 7. When the direction indicator 7 is operated, the travel road maintaining mechanism is switched to travel road deviating action corresponding safety mechanism so as to detect the existence of an obstruction in the deviating direction. In the case of the obstruction existing, a buzzer 8 is actuated to call a driver' s attention to it.
