40 years of Bosch ABS anti-lock braking system

 In 1978, Bosch was the first supplier to launch the anti-lock braking system (ABS) developed together with the automotive industry onto the market. As most new developments, ABS was first used in upper-class passenger cars such as Mercedes A-class or BMW 7-series. Soon, it also became available as standard equipment for the compact class – at first at an extra charge, then as standard. By 1990, some six million vehicles worldwide had already been equipped with Bosch ABS. Its effect on increased road safety was as evident as to lead the automotive manufacturers to commit themselves to equip all passenger cars built from mid-2004 onwards with ABS as standard equipment. As of early 1991, trucks with a gross vehicle weight exceeding 3.5 tons and buses with more than 8 seats could only be registered if they had been equipped with ABS. Finally, anti-lock braking systems became available for motorcycles as well thus preventing serious accidents caused by wheel lockups. Since early 2016, ABS has become obligatory for all new motorcycles with a displacement exceeding 125 cm³. And since 2017, all newly registered bikes are to be equipped with ABS.

Continuous further development of Bosch ABS components

Once a speed sensor informs the control unit about an imminent wheel lockup, the latter sends a signal to the hydraulic modulator causing it to reduce the brake pressure. This prevents the wheel from locking. Throughout the last 40 years, Bosch has continuously been advancing the ABS: The system components have become ever smaller, more compact and more powerful.
