Mercedes-Benz introduces automatic braking

Stuttgart, Germany – Mercedes-Benz has announced its new Pre-Safe brake, which will be offered on the S-Class and CLS-Class beginning in the fall of 2006. The company says that Pre-Safe brake, the only system of its kind in the world, automatically brakes the car before an impending rear-end collision.

The new system complements Brake Assist Plus (BAS PLUS), which was introduced last year; that system provides visual and audible warnings if it detects that the vehicle is about to run into a vehicle in front, and automatically calculates the brake force required in order to prevent the crash. This brake boosting force is available the moment the driver steps on the brake pedal.

If the driver does not react to the BAS PLUS warnings and there is severe danger of a collision, the Pre-Safe brake triggers automatic partial braking, and decelerates the vehicle at up to 0.4 g, the equivalent of around 40 per cent of the maximum braking performance. This partial braking provides the driver with a further clear prompt to take action, on top of the visual and audible warnings. If the driver immediately activates the brake, maximum braking force will be available, which may make it possible to prevent the collision at the last moment. If this is not possible, the Pre-Safe brake reduces the severity of the impact.
