An audible tone is used by the electronic assistant to signal how much room the driver has left at the front, the sides and the rear. The frequency of the signal tone increases the closer the vehicle gets to an obstacle. Once the distance falls below 30 centimeters, a continuous tone sounds. But that’s not all. The distance remaining to the obstacle is also indicated to the driver in the display, depending on which radio system model is installed. If a collision is likely, then the maneuver braking function intervenes.
Emergency braking at the last possible moment allows the assistant to reduce the severity of a collision, or even to prevent it altogether. Maneuver braking is active when reversing, at a speed from 1.5 to 10 km/h, and when driving forwards, from 2.5 to 10 km/h. When the function is not required, then it can be disabled temporarily or permanently – either by using the radio system or by using a button.
“Maneuver braking protects the driver from a collision. It prevents unpleasant damage to the bumper, and to any objects near the vehicle,” says developer Lynn Brennecke.
