Bosch's Electronic Stability Program (ESP) Marks 30 Years

Robert Bosch GmbH is marking the 30th anniversary of its Electronic Stability Program (ESP), a significant safety innovation introduced in 1995. The system, designed to prevent loss of vehicle control, has become a standard feature in modern vehicles.

Bosch reports that by 2025, ESP will have helped avert around 750,000 accidents involving personal injury and saved more than 22,000 lives within the European Union and the UK alone. Globally, the company had supplied over 350 million units of the anti-skid system by 2020.

The development of ESP was a collaborative effort, notably with Daimler-Benz, which accelerated its integration into series production. The system's core component is a yaw-rate sensor, which detects unintended rotation. ESP can then intervene by braking individual wheels and reducing engine power to stabilize the vehicle, especially during emergency maneuvers.

Engineers faced challenges in developing the yaw-rate sensor for automotive use, adapting principles from aerospace engineering. The successful mass production of this crucial component, which was later miniaturized using micromechanical technology, underscored Bosch's engineering capabilities and commitment to safety.
