Forward collision avoidance or mitigation
Forward collision avoidance systems use forward-looking sensors to alert drivers with visual or auditory cues when the vehicle is getting too close to the one in front and a crash is likely to occur. If the driver doesn't respond to the warning, some systems will ready the seatbelt pretensioners while others (like Volvo's City Safety) will pre-charge the brakes and make the emergency braking assist system more sensitive so that the car is ready to respond more quickly.
The most effective systems, experts say, are the ones that combine forward collision warning with automatic braking.
