LANE DEPARTURE ALERT SYSTEM


  1. FUNCTION


    1. The pre-crash safety city sensor captures the road image up to approximately 50 m (164 ft.) ahead of the pre-crash safety city sensor.

    2. The pre-crash safety city sensor detects lane markers and calculates the radius to the center of the lane, the vehicle center position disparity among the distances from each left and right lane marker and the angle disparity between the vehicle traveling direction and each left and right lane marker.

    3. When one of the following operations is conducted, the pre-crash safety city sensor angle must be adjusted. For details, refer to the Repair Manual.


      1. The pre-crash safety city sensor is removed and reinstalled or replaced.

      2. Parts relating to the tires or suspension are replaced or adjusted.

      3. Excessive force is applied to the pre-crash safety city sensor.

    4. The pre-crash safety city sensor calculates the estimated position which the front wheel will reach based on the information collected, vehicle speeds and front wheel positions. When the pre-crash safety city sensor determines that the front wheel is about to cross the lane marker, the pre-crash safety city sensor activates the lane departure alert system, displays a warning indicator on the multi-information display and sounds the buzzer.

    5. The lane departure alert system does not operate if the vehicle approaches the lane marker at a shallow angle, but does not cross it.
