GERMANY: Bosch predictive emergency braking system goes into series production
Author: just-auto.com editorial team | 30 April 2010
The Bosch automatic emergency braking system has gone into series production.
It provides support for drivers in critical situations in which there is the threat of a rear-end collision.
“Roughly 80 percent of drivers do not hit the brakes at all before a rear-end collision, or do not use the car's full braking capacity,” says Dr. Werner Struth, president of the Bosch Chassis Systems Control division, summarizing an analysis of GIDAS, the German accident database.
The technical basis of this system is the ESP electronic stability program and the LRR3 long-range radar sensors of the ACC adaptive cruise control system, which are complemented by a video sensor.
The functions now feature for the first time in the new Audi A8, as part of the “pre-sense” package.
The Audi A8 features two long-range radar sensors, which are housed at the left and right of the front bumper. These new Bosch generation 3 sensors can detect objects within a beam width of approximately 40 degrees at a distance of up to 250 metres, and can determine their position and speed. The video camera is positioned behind the front windscreen, at the same height as the rear-view mirror. The advantage of video technology is the high level of information content, which makes people, vehicles, or traffic signs easy to identify, Bosch says.
The radar signals deliver precise data as to the position and speed of the people, vehicles, or traffic signs captured in the video images.
Of all the accidents involving injury and fatalities in Germany, 15 percent are rear-end collisions.
