System Function
The front camera (FR_CMR) supports the following functions by using the data recognized by the front camera (lane/light source/vehicle/pedestrian/motorcycle), and car signals (CAN communication).
- Forward Collision-Avoidance Assist (FCA): This driving safety system sends warning to the driver for possible dangers and assists the braking of the vehicle to help avoid collision with any kind of obstacles that are in front of the car while driving. The FCA recognizes the position and the speed of the front obstacles (vehicle/pedestrian/two-wheeled vehicle) using the front camera/forward radar, sends visual/audible warning to the driver when a collision with the front obstacle is expected and helps the driver to avoid the collision by assisting to control the brake. However, the driver must keep an eye on the forward for safety because the front camera/forward radar may not operate normally in certain situations where the obstacles cannot be easily recognized.
- Lane Keeping Assist (LKA): This driving safety system sends warning to the driver for possible dangers and controls the steering wheel when the system judges that the car is off the lane, reducing the risk of getting into an accident while driving. The LKA sends the driver the visual/audible/tactical warning by using the data about lanes, which is obtained by the front camera, the operational status of the turn signal lights, and helps the driver to avoid the collision by assisting to control the steering wheel. However, the front camera may not operate normally in certain situations where the locations or the boundaries of the lanes are hard to be identified.
- Driver Attention Warning (DAW): This system warns the driver to avoid accidents if it judges that the driver is driving inadvertently. The DAW sends the driver visual and audible warnings if an inadvertent driving is detected by analyzing the driving pattern of the driver in consideration of the lane condition recognized by the front camera and the data on the speed/steering wheel angle/brake operation of the vehicle. However, the front camera may not operate normally in certain situations where the camera fails to obtain data about surroundings.
- High Beam Assist (HBA): This system controls the operation of high beam to improve sight distance as much as possible by minimizing glare from other vehicles when driving at night or with no or less light. By using a forward camera, the HBA identifies where the light comes from, (whether it is from a vehicle in the front/across or a street). When there is light, the system turns the high beam OFF and when there is no light, it turns the high beam ON. However, the front camera may not operate normally in certain situations where the camera fails to obtain data about surroundings.
