The best protection against crashes is to prevent them. For more than 30 years Bosch has been developing active safety systems that significantly reduce the number of crashes, despite increasing traffic density. Bosch introduced the world’s first antilock braking system (ABS) for passengers in 1978, a milestone in the area of active driving safety. In an emergency braking situation, ABS prevents a vehicle’s wheels from locking and ensures safe braking: the vehicle remains steerable and stable. Bosch launched a further development of ABS technology for passenger cars in 1987 with its traction control system (TCS). This technology improves a vehicle’s traction by preventing wheel spin when a vehicle starts off or accelerates, particularly on a slippery or wet road surface.
In 1995, active driving safety reached yet another dimension thanks to the introduction of Bosch’s ESP® technology. ESP incorporates the functions of ABS and TCS, with the additional benefits of stability control, supporting the driver in all situations. It detects if skidding is imminent and intervenes by applying braking power to individual wheels and/or reducing engine power in order to restore the vehicle's stability.
The foundation of these technologies are Bosch sensors, which provide precise data to inform the systems’ management of these critical situations.
