Forward Collision Warning (FCW) System Overview
A forward collision warning system is an advanced safety technology feature that is included on some vehicles. Forward or front collision warning systems use sensors to monitor the speed of the vehicle, the speed of the vehicle in front of it, and the distance between both vehicles. If the vehicle with the collision warning system gets too close to the vehicle ahead of it, the system will alert the driver and warn them about the potential for a crash. This warning may be given via a noise alert, a visual display, or another method.
Although FCW systems are able to notify drivers when the vehicle is at risk of a crash, these systems cannot take control of the vehicle. They are also only able to detect potential crashes between the vehicle and the vehicle ahead of it. They will not detect or warn about other types of crashes from the side or the back. However, some FCW systems are able to detect pedestrians in front of the vehicle, as well as other cars.
Some newer vehicles with collision warning systems may also come with automatic braking systems. While these systems are separate, they may work together to allow the vehicle to automatically slow down or stop when a potential accident is detected.
How Does a Forward Collision Warning System Work?
FCW systems are designed to work in several ways. Some of these systems work by using radar, lasers, or cameras.
Radar forward collision warning systems work by emitting a radio wave from the front of the vehicle. This radio wave bounces off of surrounding objects and cars and provides feedback to the safety system about the vehicle’s location in relation to other cars. Laser systems work by emitting a laser beam from the front of the car, which can measure the distance between the vehicle and the car ahead. The system compares this distance with the speed at which the car is traveling and alerts the driver to potential crashes. The final type of collision system uses cameras. The camera is placed at the front of the vehicle, and is connected to an electronic image processor that can analyze the distance between the camera and the vehicle ahead.
When the radar, laser, or camera detects that the vehicle may be in danger of crashing, it may alert the driver by setting off an alarm or other sound. Lights on the dashboard or a visual image display may also light up.
Are There Any Limitations?
According to the Insurance Institute for Highway Safety, front collision warning systems may reduce rear-end car accidents by almost 30 percent. However, although many auto manufacturers and retailers market vehicles with forward collision warning systems as being a safe option for families, some consumers claim that these systems do not work as well as advertised. While these systems may be able to warn drivers about some potential crashes, they are unable to prevent all crashes from occurring. Additionally, drivers must still be alert and pay attention to their surroundings, as many of these systems do not automatically brake.
While some systems are able to detect animals, pedestrians, or bicyclists in the vicinity of the vehicle, other systems may only be able to detect other vehicles. According to the American Automobile Association, even systems that specifically claim to be able to detect pedestrians may frequently malfunction. Additionally, the system may not work well on roads with sharp curves or hills, or during inclement weather.
What Happens When a Front Collision Warning System Stops Working?
If your forward collision warning system stops working, you may be able to bring your vehicle to the dealership and have it checked out. In the meantime, drivers may want to be especially aware of their car’s position in relation to other vehicles and pay attention to driving conditions. While a malfunctioning collision warning system may sometimes be fixable, it may also be a sign of a defective vehicle.
Why Is Your Kia Forward Collision Warning System Not Working?
According to some consumers who own Kia vehicles equipped with collision warning systems, these systems may frequently fail. A recent recall from Kia confirmed these reports. More than 11,000 of Kia 2019 Optima sedans may be affected by a defect that prevents an automatic braking system from engaging when the collision warning system senses an impending crash. Drivers of these vehicles who are expecting their car to automatically brake when it approaches another vehicle may be at risk of getting into accidents when the braking system fails.
Consumers who have purchased a vehicle with a collision warning system may be eligible to speak with an experienced attorney about their legal options if this system is defective.
