Hyundai Santa Cruz: Front View Camera System / Description and Operation

- Description and Operation Blcok Diagram

   

• This system monitors the driving situations through the front view camera and front radar. Thus, for a situation out of the sensing range, the system may not normally operate.

The System may be limited when :

• The radar sensor or camera is blocked with a foreign object or debris.

• The camera lens is contaminated due to tinted filmed or coated windshield, damaged glass, or stuck of foreign matter (sticker, bug, etc.) on the glass.

• Inclement weather such as heavy rain or snow obscures the field of view of the radar sensor or camera.

• The target in front is too small to be detected

• The vehicle in front is an oversize vehicle or trailer that is too big to be detected by the camera recognition system (for example a tractor trailer, etc.).

• The camera's field of view is not well illuminated (either too dark or too much reflection or too much backlight that obscures the field of view)

• The vehicle in front does not have their rear lights ON or their rear lights are located in an unsual location (modified).

• In case of damage to the front camera or front radar.

• The windshield glass is fogged up and the clear view of the road has been obstructed.

System Function Front view camera (FR_CMR) supports the following functions by using the data recognized by the front view camera (lane / light source / vehicle / pedestrian / motorcycle), and car signals (CAN communication).

1.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 / cyclist) using the front view camera / front 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 view camera / front radar may not operate normally in certain situations where the obstacles cannot be easily recognized.

2.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 / warning by using the data about lanes, which is obtained by the front view 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 view camera may not operate normally in certain situations where the locations or the boundaries of the lanes are hard to be identified.

3.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 view camera and the data on the speed / steering wheel angle / brake operation of the vehicle. However, the front view camera may not operate normally in certain situations where the camera fails to obtain data about surroundings.

4.Lane Following Assist (LFA): This system is designed to improve passenger convenience by controlling the steering wheel to keep the vehicle at the center of the lane, helping to reduce operating load while driving. The LFA helps control the steering wheel to keep the car at the center of the lane by using the data about lanes and road boundaries obtained by the front view camera. However, the driver must keep an eye on the forward for safety because the system may not operate normally in certain situations where the front view camera fails to obtain information about front view.

5.Highway Driving Assist (HDA) : HDA helps maintain a set distance and speed from the vehicle ahead when driving on a highway and helps center the vehicle in the lane while driving, even through a curve.
