TRW's Adaptive Cruise Control (ACC) technology improves upon the function of standard cruise control by automatically adjusting the vehicle speed and distance to that of a target vehicle. ACC uses a long range radar sensor to detect a target vehicle up to 200 meters in front and automatically adjusts the ACC vehicle speed and gap accordingly. ACC automatically decelerates or accelerates the vehicle according to the desired speed and distance settings established by the driver. As per standard cruise control the driver can override the system at any time.     Figure 1 The ACC vehicle approaches the target vehicle at its set speed of 70 mph. TRW's ACC System senses the impeding vehicle.   Figure 2 TRW's ACC takes action, automatically adjusting the ACC vehicle's speed to match the target vehicle's speed. If the ACC vehicle loses its target (for example during a lane change) then the ACC vehicle will automatically reaccelerate to its 70 mph set speed. Product Features Assists with driver overload and stress in congested highway situations. Assists with key driver functions (accelerating and braking) while cruising. Maintains a set distance automatically between vehicles. Serves as a cornerstone to advanced safety systems.
