System Operation

The functional requirements of MFC are as follows:

1. Lane Keeping Assist (LKA)
   • It operates when the LKA function is set and the vehicle speed is over 60 km/h.

     (LKA Function Setting: LKA Switch ON, USM LKA Mode)

   • The lines should be clearly separated, and both lanes should be detected.
   • The driver's hand should be placed on the steering wheel and the function is canceled if ignoring the steering force when the LKA function is activated.
   • LKA will operate If the lane change is made arbitrarily while the turn signal lamp and emergency light switch are OFF.
   • LKA operates at a lane width of 2.8m or more and 4.3m or less.
   • If the vehicle crosses more than 40% of the width of the vehicle, it is judged that the lane is deviated to change the lane and the LKA function is canceled.
   • In the following cases, the LKA may not operate.
     1. When driving on a steep curve
     2. Sudden braking or sudden change of lane
     3. When the ESC/VSM function is working
2. High Beam Assist (HBA)
   1. If the light switch is pushed to the instrument panel, the high beam is turned on and the HBA is OFF.
   2. Operates when the vehicle speed is more than 45 km/h.
   3. Details of the operation according to the state of the lighting switch during operation of the High Beam Assist (HBA) system are as follows:
   4. If the light switch is pushed to the instrument panel, the high beam is turned on and the HBA is OFF.
      • If the light switch is pulled up with the high beam being turned off, the high beam is turned on and HBA remains ON. (When you release the hand, the switch moves to the center and the high beam is turned off.)
      • When the light switch is turned on with the high beam turned on by the HBA, the high beam is turned off and the system is released.
      • If you turn the light switch from AUTO to the headlight position, the high beam is turned off and the system is released.
      • During HBA operation with high beam is turned on, the headlamp automatically switches to the high beam off state if:
   5. Detecting the headlights or tail lights of an approaching vehicle
      • Detecting the headlights or tail lights of an approaching vehicle
      • Detecting the headlights or tail lights of bicycles and motorcycles
      • The surroundings are bright enough not to turn on the headlights
      • There is a street light or other light in front
      • The light switch is not in the AUTO (auto light) position
      • The HBA is turned off
      • The vehicle speed is reduced to 35 km/h or less
   6. Even if the HBA operating condition is satisfied, it does not work in the weekly time zone.
   7. Recognizes the lamp source of the preceding vehicle in normal nighttime environment and automatically high beam turns on or off.
