Mitsubishi Forward Collision Mitigation (FCM) is a radar-based autonomous emergency braking system. A single 77GHz radar is situated behind the front grille and is used to detect objects up to around 200m ahead which might present a risk of collision. The system operates up to a maximum speed of 180km/h. In the first stage, when the risk of collision is low, FCM issues a visual and audible warning to alert the driver to the threat. At the same time, the brakes are pre-filled and brake assist is activated, which boosts the braking pressure should the driver respond to the warning and apply the brakes. If the driver does not respond and the risk of collision increases, the system continues to warn the driver but also autonomously applies moderate braking, to begin to mitigate the severity of any collision but also to serve as an additional warning to the driver. If the risk of collision escalates, FCM autonomously applies a high brake pressure to try to avoid the accident or to reduce its severity. Up to 30km/h, the system will apply a maximum deceleration of 8ms-2. Beyond that speed the maximum is 6ms-2.
