Staying on track

Milestones from 25 years of ESP® at Bosch

Just under half a million accidents involving personal injury avoided and 15,000 lives saved in the EU alone – this is the track record of ESP®, first launched in 1995. The story behind this achievement is one that began more than 25 years ago. The following text present the milestones in the development of the electronic stability program at Bosch:

1983: Bosch researchers float some first ideas about how to improve stability when braking hard in bends. They base their ideas on the ABS antilock braking system launched in 1978. An initial proposal is to flexibly adapt each wheel’s slip to improve control over the vehicles when braking in bends.

1984: Effective July 1, a development team is set up. Its task is to use ABS as the basis for developing a brake control system offering improved vehicle control when skidding is imminent in a bend. In such a situation, the vehicle has to remain stable and steerable as far as the laws of physics will allow.

1992: A joint project unit is set up near the Bosch location in Schwieberdingen. It is made up of engineering experts from Bosch and the automaker Daimler-Benz, which is subsequently the first to install the system. An agreement is made to develop a system for production in 36 months.

1995: ESP® has its press debut in a Mercedes-Benz S-class coupé in May, and its market launch in the coupé and sedan in September (as an extra, standard feature only with the most powerful, 12-cylinder engine).

1997: A Mercedes-Benz A-class vehicle rolls over while performing an extreme swerving maneuver during testing. The model was only recently launched. Following this “elk test” for a Swedish automotive magazine, the automaker decides to make ESP® a standard feature. Other automakers soon follow suit.

1998: For the first time, the yaw-rate sensor that is at the heart of the ESP® is produced as a micromechanical sensor. Bosch has been mass-producing these sensors with microscopically small movable structures since 1995. This means ESP® can be smaller, while at the same time longer-lasting, less sensitive, more reliable, and less expensive.

2003: Bosch celebrates the delivery of its 10 millionth ESP® system. The technology has now been in the market for ten years. In the years that follow, increasing volumes pave the way for this lifesaver to become established in the compact class.

2011: Traffic experts and policymakers increasingly acknowledge the benefits of ESP®. The anti-skid system is mandated in various countries, including EU member states. In the EU, the mandating process is gradual. From November 2011, it is initially mandatory for new passenger-car and commercial-vehicle types, and from November 1, 2014, for all newly registered passenger cars and commercial vehicles.

2016: In the Life Achievement category, the European Patents Office confers its European Inventor Award on Anton van Zanten. Born in the Netherlands, van Zanten headed up the 35-strong group of ESP® developers at Bosch.

2020: ESP® turns 25. Over the past quarter of a century, Bosch has continuously improved its anti-skid system, producing more than 250 million ESP® systems to date.

Mobility is the largest Bosch Group business sector. In 2023, its sales came to 56.2 billion euros, or just under 60 percent of total Group sales. This makes the Bosch Group one of the leading mobility suppliers. Bosch Mobility pursues a vision of mobility that is safe, sustainable, and exciting. For its customers, the outcome is integrated mobility solutions. The business sector’s main areas of activity are electrification, software and services, semiconductors and sensors, vehicle computers, advanced driver assistance systems, systems for vehicle dynamics control, repair-shop concepts, as well as technology and services for the automotive aftermarket. Bosch is synonymous with important automotive innovations, such as electronic engine management, the ESP anti-skid system, and common-rail diesel technology.

The Bosch Group is a leading global supplier of technology and services. It employs roughly 429,000 associates worldwide (as of December 31, 2023). The company generated sales of 91.6 billion euros in 2023. Its operations are divided into four business sectors: Mobility, Industrial Technology, Consumer Goods, and Energy and Building Technology. With its business activities, the company aims to use technology to help shape universal trends such as automation, electrification, digitalization, connectivity, and an orientation to sustainability. In this context, Bosch’s broad diversification across regions and industries strengthens its innovativeness and robustness. Bosch uses its proven expertise in sensor technology, software, and services to offer customers cross-domain solutions from a single source. It also applies its expertise in connectivity and artificial intelligence in order to develop and manufacture user-friendly, sustainable products. With technology that is “Invented for life,” Bosch wants to help improve quality of life and conserve natural resources. The Bosch Group comprises Robert Bosch GmbH and its roughly 470 subsidiary and regional companies in over 60 countries. Including sales and service partners, Bosch’s global manufacturing, engineering, and sales network covers nearly every country in the world. Bosch’s innovative strength is key to the company’s further development. At 136 locations across the globe, Bosch employs some 90,000 associates in research and development, of which nearly 48,000 are software engineers.
