ABS for Low Price Vehicles 2007-01-2752

Since in 1978 the Robert Bosch GmbH first started with series production of anti-lock braking systems over 150 million of their units have been installed world-wide. The current ABS generation 8 is a modular system which permits ABS, TCS and ESP® braking control systems to be implemented as an integrated product family.
Although the benefits of ABS in road traffic safety by significantly improving steerability and car control while braking are well known in Europe, USA, and Japan, there are still weak installation rates in emerging markets like Brazil: For vehicles sold in 2006 in the Brazilian market, the installation rate is about 14%. Major reason for this situation is the cost of ABS unit influenced by development and application work, which usually has to be carried out for each car individually.
To address this Bosch is considering a cost optimized system in between today's full performance ABS and a standard braking system without modulation. Currently 2 approaches are in evaluation:
  • To downsize the ABS hardware with respect to the limitations given by the vehicle itself. For mini cars and small vehicles the top speed and consequently the necessary braking performance is usually limited.
  • To decrease the development expenses and the testing time. Here computational simulation and quick application are necessary to reach feasibility.
