Hyundai Venue: Forward Collision-Avoidance Assist (FCA) System-Sensor Fusion / Limitations of the System

Hyundai Venue (QX) (2020-2021) Owners Manual / While Driving / Forward Collision-Avoidance Assist (FCA) System-Sensor Fusion / Limitations of the System

Forward Collision-Avoidance Assist system is designed to help monitor the vehicle ahead or a pedestrian on the roadway through radar signals and camera recognition to warn the driver that a collision is imminent, and if necessary, apply emergency braking.

In certain situations, the radar sensor or the camera may not be able to detect the vehicle or pedestrian ahead. In these cases, FCA system may not operate normally. The driver must pay careful attention in the following situations where the FCA operation may be limited.

Detecting vehicles

The sensor may be limited when:

  • The front view camera or radar sensor is blocked with a foreign object or debris
  • Inclement weather such as heavy rain or snow obscures the field of view of the radar sensor or camera
  • There is interference by electromagnetic waves
  • There is severe irregular reflection from the radar sensor
  • The radar/camera sensor recognition is limited
  • The vehicle in front is too small to be detected (for example a motorcycle or a bicycle, etc.)
  • 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 driver'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 properly turned ON
  • The outside brightness changes suddenly, for example when entering or exiting a tunnel
  • Light coming from a street light or an oncoming vehicle is reflected on a wet road surface such as a puddle in the road
  • The field of view in front is obstructed by sun glare
  • The windshield glass is fogged up; a clear view of the road is obstructed
  • The vehicle in front is driving erratically
  • The vehicle drives through a construction area, on an unpaved road, or above metal materials, such as a railway
  • The vehicle drives inside a building, such as a basement parking lot
  • The adverse road conditions cause excessive vehicle vibrations while driving
  • The vehicle in front is moving vertically to the driving direction
  • The vehicle in front is stopped vertically
  • The vehicle in front is driving towards your vehicle or reversing

Hyundai Venue. Limitations of the System

• Driving on a curve

The performance of FCA system may be limited when driving on a curved road.

In certain instances on a curved road, FCA system may activate prematurely.

Also, in certain instances the front radar sensor or camera recognition system may not detect the vehicle traveling on a curved road.

In these cases, the driver must maintain a safe braking distance, and if necessary, depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

Hyundai Venue. Limitations of the System

FCA system may recognize a vehicle in the next lane when driving on a curved road.

In this case, the system may unnecessarily alarm the driver and apply the brake.

Always pay attention to road and driving conditions, while driving. If necessary, depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

Also, when necessary depress the accelerator pedal to prevent the system from unnecessarily decelerating your vehicle.

Hyundai Venue. Limitations of the System

• Driving on a slope

The performance of Forward Collision- Avoidance Assist system may be decreased while driving upward or downward on a slope.

The front camera recognition may not detect the vehicle or pedestrian in front.

This may result in unnecessary alarm and braking when necessary. When FCA suddenly recognizes the vehicle in front while passing over a slope, you may experience sharp deceleration.

Always keep your eyes forward while driving upward or downward on a slope, and, if necessary, depress the brake pedal to reduce your driving speed in order to maintain distance.

Hyundai Venue. Limitations of the System

• Changing lanes

When a vehicle changes lanes in front of you, FCA system may not immediately detect the vehicle, especially if the vehicle changes lanes abruptly. In this case, you must maintain a safe braking distance, and if necessary, depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

Hyundai Venue. Limitations of the System

When driving in stop-and-go traffic, and a stopped vehicle in front of you merges out of the lane, FCA system may not immediately detect the new vehicle that is now in front of you. In this case, you must maintain a safe braking distance, and if necessary, depress the brake pedal to reduce your driving speed in order to maintain a safe distance.

Hyundai Venue. Limitations of the System

• Detecting the vehicle in front of you

If the vehicle in front of you has cargo that extends rearward from the cab, or when the vehicle in front of you has higher ground clearance, additional special attention is required. FCA system may not be able to detect the cargo extending from the vehicle. In these instances, you must maintain a safe braking distance from the rearmost object, and if necessary, depress the brake pedal to reduce your driving speed in order to maintain distance.

Detecting pedestrians (if equipped)

The sensor may be limited when:

  • The pedestrian is not fully detected by the camera recognition system, for example, if the pedestrian is leaning over or is not fully walking upright
  • The pedestrian is moving very quickly or appears abruptly in the camera detection area
  • The pedestrian is wearing clothing that easily blends into the background, making it difficult to be detected by the camera recognition system
  • The outside lighting is too bright (e.g. when driving in bright sunlight or in sun glare) or too dark (e.g. when driving on a dark rural road at night)
  • It is difficult to detect and distinguish the pedestrian from other objects in the surroundings, for example, when there is a group of pedestrians or a large crowd
  • There is an item similar to a person's body structure
  • The pedestrian is small
  • The pedestrian has impaired mobility
  • The sensor recognition is limited
  • The radar sensor or camera is blocked with a foreign object or debris
  • Inclement weather such as heavy rain or snow obscures the field of view of the radar sensor or camera
  • When light coming from a street light or an oncoming vehicle is reflected on a wet road surface such as a puddle in the road
  • The field of view in front is obstructed by sun glare
  • The windshield glass is fogged up; a clear view of the road is obstructed
  • The adverse road conditions cause excessive vehicle vibrations while driving

Information

In some instances, FCA system may be canceled when subjected to electromagnetic interference.

Information

This device complies with Part 15 of the FCC rules.

Operation is subject to the following two conditions:

1. This device may not cause harmful interference.

2. This device must accept any interference received, including interference that may cause undesired operation.

WARNING

  • Do not use Forward Collisionavoidance Assist (FCA) system when towing a vehicle. Application of the FCA system while towing may adversely affect the safety of your vehicle or the towing vehicle.
  • Use extreme caution when the vehicle in front of you has cargo that extends rearward from the cab, or when the vehicle in front of you has higher ground clearance.
  • FCA system is designed to help detect and monitor the vehicle ahead or detect a pedestrian in the roadway through radar signals and camera recognition. It is not designed to detect bicycles, motorcycles, or smaller wheeled objects such as luggage bags, shopping carts, or strollers.
  • Never try to test the operation of FCA system. Doing so may cause severe injury or death.
