Hyundai Santa Fe: Forward Collision–Avoidance Assist (FCA) (Sensor fusion) / System operation
Basic function
System warning and control
The basic function for Forward Collision- Avoidance Assist is to help warn and
control the vehicle depending on the collision level: ‘Collision Warning’, ‘Emergency
Braking’ and ‘Stopping vehicle and ending brake control’.
Collision Warning
- To warn the driver of a collision, the ‘Collision Warning’ warning message
will appear on the cluster and an audible warning will sound.
- If a vehicle is detected in front, the system will operate when your vehicle
speed is between approximately 6~112 mph (10~180 km/h).
- If a pedestrian or cyclist is detected in front, the system will operate
when your vehicle speed is between approximately 6~53 mph (10~85 km/h).
- If ‘Active Assist’ is selected, braking may be assisted.
Emergency Braking
- To warn the driver that emergency braking will be assisted, the ‘Emergency
Braking’ warning message will appear on the cluster and an audible warning will
sound.
- If a vehicle is detected in front, the system will operate when your vehicle
speed is between approximately 6~47 mph (10~75 km/h).
- If a pedestrian or cyclist is detected in front, the system will operate
when your vehicle speed is between approximately 6~40 mph (10~65 km/h).
- In emergency braking situation, braking is assisted with strong braking
power by the system to help prevent collision with the vehicle, pedestrian or
cyclist ahead.
Stopping vehicle and ending brake control
- When the vehicle is stopped due to emergency braking, the ‘Drive carefully’
warning message will appear on the cluster. For your safety, the driver should
depress the brake pedal immediately and check the surroundings.
- Brake control will end after the vehicle is stopped by emergency braking
for approximately 2 seconds.
Junction Turning function (if equipped)
System warning and control
Junction Turning function will help warn and control the vehicle depending on
the collision level: ‘Collision Warning’, ‘Emergency Braking’ and ‘Stopping vehicle
and ending brake control’
Collision Warning
- To warn the driver of a collision, the ‘Collision Warning’ warning message
will appear on the cluster and an audible warning will sound.
- The system will operate when your vehicle speed is between approximately
6~19 mph (10~30 km/h) and the oncoming vehicle speed is between approximately
19~44 mph (30~70 km/h).
- If ‘Active Assist’ is selected, braking may be assisted.
Emergency Braking
- To warn the driver that emergency braking will be assisted, the ‘Emergency
Braking’ warning message will appear on the cluster and an audible warning will
sound.
- The system will operate when your vehicle speed is between approximately
6~19 mph (10~30 km/h) and the oncoming vehicle speed is between approximately
19~44 mph (30~70 km/h).
- In emergency braking situation, braking is assisted with strong braking
power by the system to help prevent collision with the oncoming vehicle.
Information
If the driver's seat is on the left side, Junction Turning function will operate
only when the driver turns left. If the driver's seat position is on right side,
the function will operate only when you turn right.
Stopping vehicle and ending brake control
- When the vehicle is stopped due to emergency braking, the ‘Drive carefully’
warning message will appear on the cluster. For your safety, the driver should
depress the brake pedal immediately and check the surroundings.
- Brake control will end after the vehicle is stopped by emergency braking
for approximately 2 seconds.
WARNING
Take the following precautions when using Forward Collision-Avoidance Assist:
- For your safety, change the Settings after parking the vehicle at a
safe location.
- With ‘Active Assist’ or ‘Warning Only’ selected, when ESC is turned
off by pressing and holding the ESC OFF button for more than 3 seconds, Forward
Collision-Avoidance Assist will turn off automatically. In this case, the system
cannot be set from the Settings menu and the warning light will illuminate on
the cluster which is normal. If ESC is turned on by pressing the ESC OFF button,
Forward Collision-Avoidance Assist will maintain the last setting.
- Forward Collision-Avoidance Assist does not operate in all situations
or cannot avoid all collisions.
- The driver should hold the responsibility to control the vehicle. Do
not solely depend on Forward Collision-Avoidance Assist. Rather, maintain a
safe braking distance, and if necessary, depress the brake pedal to reduce driving
speed or to stop the vehicle.
- Never deliberately operate Forward Collision-Avoidance Assist on people,
animal, objects, etc. It may cause serious injury or death.
- Forward Collision-Avoidance Assist may not operate if the driver depresses
the brake pedal to avoid collision.
- Depending on the road and driving conditions, Forward Collision- Avoidance
Assist may warn the driver late or may not warn the driver.
- During Forward Collision-Avoidance Assist operation, the vehicle may
stop suddenly injuring passengers and shifting loose objects. Always have the
seat belt on and keep loose objects secured.
- If any other system’s warning message is displayed or audible warning
is generated, Forward Collision-Avoidance Assist warning message may not be
displayed and audible warning may not be generated.
- You may not hear the warning sound of Forward Collision-Avoidance Assist
if the surrounding is noisy.
- Forward Collision-Avoidance Assist may turn off or may not operate
properly or may operate unnecessarily depending on the road conditions and the
surroundings.
WARNING
- Even if there is a problem with Forward Collision-Avoidance Assist,
the vehicle’s basic braking performance will operate normally.
- During emergency braking, braking control by the system will automatically
cancel when the driver excessively depresses the accelerator pedal or sharply
steers the vehicle.
CAUTION
- Forward Collision-Avoidance Assist operating speed range may reduce
due to the conditions of the vehicle or pedestrian in front or surroundings.
Depending on the speed, the system may only warn the driver, or the system may
not operate.
- Forward Collision-Avoidance Assist will operate under certain conditions
by judging the risk level based on the condition of the oncoming vehicle, driving
direction, speed and surroundings.
Information
In a situation where collision is imminent, braking may be assisted by Forward
Collision-Avoidance Assist when braking is insufficient by the driver.
Forward Safety
With the engine on, select ‘Driver Assistance - Forward Safety' from the Settings
menu to set whether or not to use each function.
- Id 'Active Assist' is selected, Forward Collision-Avoidance Assist
- will warn the driver with a warning message and an audible warning depending on
the collision risk levels...
System malfunction
When Forward Collision-Avoidance Assist is not working properly, the ‘Check Forward
Safety system(s)’ warning message will appear, and the
and
warning lights
will illuminate on the cluster...
Other information:
The aspect ratio is lower than 50 on low aspect ratio tires.
Because low aspect ratio tires are optimized for handling and braking, their
sidewall is a little stiffer than a standard tire. Also low aspect ratio tires tend
to be wider and consequently have a greater contact patch with the road surface...
Description of ESP
ESP recognizes critical driving conditions, such as panic reactions in dangerous
situations, and stabilizes the vehicle by wheel-individual braking and engine
control intervention.
ESP adds a further function known as Active Yaw Control (AYC) to the ABS, TCS,
EBD and ESP functions...
