A brief distraction or loss of concentration can often be sufficient to cause a rear-end collision. A driver traveling at 80 km/h (50 mph) who is distracted for just one second covers a distance of over 22 meters (24 yards) in this time. In critical situations, seconds are decisive in determining whether the driver can avoid a rear-end collision.

Accident research shows that prior to rear-end crashes most drivers do not apply the brake pedal strongly enough, or do not apply the brakes at all. That is why Bosch has developed the Predictive Emergency Braking System. It is based on the networking of surround sensors with the Electronic Stability Program (ESP®) and is a multi-stage approach, supporting the driver in the event of an impending rear-end collision. Depending on the situation, rear-collisions can potentially be avoided, or their consequences significantly reduced.
