What It Is and How It Works

What It Is and How It Works

WHAT IS IT?

In addition to helping your car maintain a pre-determined speed like standard cruise control, ACC lets your vehicle maintain a predetermined following distance as well. If that following distance grows short, too short to get your vehicle stopped in an emergency braking situation, ACC will alert you to the hazard by issuing a visible or audible forward collision warning. Some systems will take even further action. When ACC is paired with emergency braking capability, it can automatically slow your car to stop if you don’t hit the brake. Others have Stop and Go capability that can automatically slow your vehicle to a complete stop in an emergency, if needed, or simply slow the car down to match the pace of traffic. When traffic starts to speed up again, the vehicle compensates; i.e., accelerates up to the original pre-determined speed and following distance without any input from the driver. In addition to managing acceleration and braking, some systems with what’s called Traffic Jam Assist even provide steering guidance (Audi, Mercedes-Benz, others). It is a piloted driverless experience, or as close to one as you will come in a production vehicle.

HOW DOES IT WORK?

As far as the driver is concerned, the same way standard cruise control does. The system is turned on via a button on steering wheel or stalk jutting out from the steering column. The driver accelerates to the desired speed, then presses a “Set” button to determine driving speed (mph can be increased or decreased by raising or lowering the ACC stalk or pushing the plus or minus buttons on the steering wheel). With the speed set, the driver can determine a comfortable following distance. From here, ACC uses a mix of long and short-range radar sensors to monitor the traffic around the vehicle, paying particularly close attention to the presence, distance and speed of the car in front of you. Some ACC systems employ lasers or stereoscopic cameras instead of radar to determine the presence, speed and distance between vehicles.
