Adaptive Cruise Control

GM's first application of its Adaptive Cruise Control (ACC) technology was on the Cadillac XLR. While not a substitute for full driver attention, the system greatly expands the convenience of cruise control.

How it works

Adaptive Cruise Control uses a high-performance 76GHz radar sensor mounted at the front of the car to detect vehicles in front of it. The ACC logic determines which of the detected vehicles is the closest vehicle ahead of it. If the lane ahead is clear, the system will maintain the set speed, just like conventional cruise control. If a slower moving vehicle is in the same lane as the ACC vehicle, the system will adjust vehicle speed using engine power and brakes to maintain a constant following distance. If a vehicle or object in the path of the car is at a significantly slower speed, the system provides visible and audible alerts to the driver indicating that the driver should take control of the car. ACC is enabled by conventional set/resume controls and is monitored through a graphic representation (for example, a head-up display). The driver can also adjust the following distance using the ACC Gap Up/Down switches.
