The EU directive makes brake assist mandatory. Audi use the standard Bosch system first.
Sudden Brake Assist Systems (also known as Brake Assist or BAS) are becoming mandatory for all new passenger cars and light commercial vehicles in the European Union. The standard will enter into force for all new vehicles from 24 February 2011. These legal requirements are part of a new EU regulatory program aimed at improving pedestrian safety. Brake Assist systems assist the driver in driving situations requiring an emergency stop. If a person behind the wheel suddenly and abruptly presses the brake pedal, the system recognizes this action in response to a critical road situation and quickly increases the braking force, helping to shorten the braking distance and prevent a possible collision. According to EU studies, if all vehicles are fitted as standard with brake booster, up to 1 serious pedestrian traffic accident can be prevented in Europe every year.
We will see the system in series production for the first time in 2010 on Audi vehicles, and the supplier is Bosch. The Bosch Emergency Stop Brake System provides three levels of driver support. Collision Warning The system detects the presence of potential obstacles and warns the driver - first with an audible or visual signal and then with a short, hard brake application. If the driver then responds by pressing the brake pedal, the system activates the brake booster, which increases the pressure in the braking system and shortens the braking distance to avoid hitting an obstacle. It is also possible that the driver does not respond to the warning and an impact becomes imminent. In this case, the system applies maximum braking force shortly before impact. Research specialists Bosch based on the GIDAS (German In-Depth Accident Study) database, which contains accurate information on a huge number of accidents, shows that the use of a preventive emergency braking system can prevent almost 3/4 of rear accidents with passenger injuries.
The EU directive will make brake assist systems mandatory and will also lead to stricter requirements for additional design measures to mitigate a possible impact in front of vehicles. The main goal is to reduce the risk of injury in accidents involving pedestrians and cyclists. Improving road safety is also the goal of another legislative measure that came into force in August 2009 - the phased introduction of the mandatory ESP stabilization system for all vehicles by November 2014. In addition, this is provided from November 2015. g. trucks should also be equipped with modern emergency braking systems, as well as devices to keep track of the lane and warn the driver in case of unintentional departure.
