Forward Collision Mitigation

How does it work?

Forward collision mitigation (FCM) systems detect the distance and speed at which a vehicle is travelling forward toward a vehicle ahead and apply brakes if the driver does not respond on their own. These systems respond to the clear need of drivers to constantly monitor their environment, and quickly prevent unexpected events.

Forward collision mitigation should not be confused with forward collision warnings. A mitigation system will warn the driver and slow down the vehicle, while a warning system will only warn the driver. In addition, some systems will only detect other moving vehicles or vehicles travelling at a minimum speed, while others will detect both moving and stationary vehicles. Implementations of this class of technology may include forward collision warning (FCW) and brake assist (BA) technology that pre-prepares the braking system.

Pros

  • Many drivers do not realize when they are entering a possible crash situation which may result in a delayed reaction and hence a collision. These mitigation systems work to reduce the chance of collisions and reduce the severity of collisions when they occur.
  • It represents a clear benefit for people with disabilities or older adults who cannot react as quickly to certain incidents.
  • Many drivers are not used to dealing with safety-critical braking situations and do not apply enough braking force to avoid a crash. FCM is designed to reduce the number and severity of these types of collisions.

Cons

  • Current systems are not capable of preventing all possible forms of crash; the driver must always maintain proper control of the vehicle.
  • Currently, climate and environmental conditions (e.g., snow, heavy rain, fog) can influence the system. Camera-based systems are less effective at night than radar-based systems. In addition, camera-based systems can be “blinded” by direct sunlight (e.g., early dawn and late sunset). Both radar and camera systems can be obscured by snow/ice buildup in front of sensors.
