Automobile manufacturers have enhanced passengers’ and pedestrians’ safety with new systems and sensors. A forward collision warning system is a modern safety system that detects any object and warns the driver with audio and visual alerts.
Front collisions may happen in high-traffic areas when the driver loses attention. However, the front collision warning system alerts the drivers, and some vehicle models even apply emergency brakes when it detects a slow or stopped car or object.
Let’s go through the complete details of the forward collision warning (FCW) system and learn about its working and how to use it.
WHAT IS A FORWARD COLLISION WARNING SYSTEM?
The technology has evolved over the years, with modern vehicles consisting of numerous sensors and systems to protect the occupants and car from damage. That said, a forward collision warning system is a modern car safety feature that uses radars to detect slow-moving or stationary objects in front of your vehicle.
The FCW system alone will not apply brakes to your vehicle. It will only detect the objects in front and alert via audio and visual signals. However, new vehicle models have forward collision warning systems integrated with an automatic emergency braking system that brakes the car alongside alerting.
While the system paired with automatic emergency braking may not protect your vehicle from a crash every time, it will reduce the crash severity. The FCW system in some vehicle models can detect cars easily but may not sense motorcycles, humans and other objects.
The weather conditions may also impact its performance. For instance, the system may not function accurately in rain or dust storms. Therefore, you should always follow the safety tips and precautions while driving in bad weather.
HOW DOES THE FORWARD COLLISION WARNING SYSTEM WORK?
FCW system functions with the help of different sensors. Sensors located in front of the vehicle scan the road ahead. The radars detect how close the object is to your car. This system then warns the driver with visual alerts, audio beeps, seat vibrations or quick brake pulse.
Although a driver should always be cautious, the FCW system ensures the safety of passengers and the vehicle. These warning signals allow the driver to take action on time, such as steering the automobile or applying brakes.
The forward collision warning system has the following parts:
- On/off switch
- Distance and speed sensors
- Indicator and warning signals
An FCW system uses the following sensors and systems to work accurately:
SPEED AND DISTANCE SENSORS
The speed and distance sensors work in tandem with the car’s computer and send the signals to the forward collision warning system. Some distance sensors use radar technology, whereas others use laser technology. Detecting the slow or stopped vehicles and objects, the system alerts the drivers instantly.
RADAR
The FCW system sends radar waves to reflect objects in front of the car. This radar system uses speed and distance sensors to detect if a crash is imminent.
AUTOMATIC EMERGENCY BRAKING
If your vehicle has an automatic emergency brake, the forward collision warning system will send signals to the emergency brake system. After that, the system will help protect the vehicle from an imminent collision by applying brakes on time.
HOW TO ACTIVATE/DEACTIVATE FCW
Most vehicle models have the forward collision warning system that activates after they cross 20 km/h speed. You can activate or deactivate it with a switch on the steering wheel or beside it. Moreover, you can use the infotainment system to operate the FCW system.
HOW TO USE THE COLLISION WARNING SYSTEM
As a driver, you must maintain a safe distance from the vehicles in front of you. When you receive an alert on the heads-up display or infotainment screen, steer the car and use brakes to avoid a collision.
That wraps up the complete information on the working of the front collision warning system. You can find this system in vehicle models with different names used by automotive brands. The following are a few names used by various automobile manufacturers:
- Pre-crash system
- Forward crash warning
- Collision mitigation system
- Collision avoidance system
- Forward collision avoidance system
- Rear-end crash avoidance system
- Automotive collision avoidance system
When buying a used car for sale in the UAE, ensure your vehicle has all the safety systems intact. These systems will help mitigate the risk of crashes and accidents. You can learn more about the working of collision avoidance systems and understand how to use them.
