The major step in promoting vehicle safety in the past decade is undoubtedly the advances made in developing automatic anti-skid systems. The authors’ company, Alfred Teves GmbH, has made a significant contribution with an intensive 12 year anti-skid program. After successful presentation of the Mk I System in the late 70's, further progress led to the Mk II Anti-Skid System, which has attracted wide attention. It will see production in 1984 in advanced European vehicles.The main feature of this new system is its integral and highly compact design, using a single hydraulic medium, namely brake fluid. A hydraulic booster, master cylinder, energy supply with electro-pump and accumulator, and a solenoid valve block form the assembly.Another key element is the first passenger car use of microprocessors which double processing of all information and mutually check every step. These microprocessors are also highly adaptable to program changes, without affecting the hardware.This new Anti-Skid design has unique features which will set a standard for all future systems, especially as the demand for anti-skid spreads from today's upperclass vehicles to small and medium size vehicles, and the very significant safety advances are made available to the broadest range of the motoring public.
