Boxberg – Electromobility is attracting new manufacturers to the market worldwide. At Bosch, a separate unit takes care of these customers who all have one thing in common: They increasingly demand system solutions rather than individual components. Bosch wants to support these new entrants just as it supports traditional car manufacturers in bringing electric vehicles to the market faster than before.

From a pre-integrated module to a complete solution

As part of a development alliance with the chassis and automotive technology expert Benteler, Bosch is showing how its products for electric vehicles can be integrated and which innovative, cross-domain functions – for example between steering and brakes – can be realized. Benteler takes care of the mechanical integration by embedding corresponding components and subsystems in a so-called rolling chassis. The rolling chassis is a ready-to-drive modular platform on which car bodies of a wide variety of vehicle types can be flexibly assembled.

The scalable concept using pre-integrated modules enables new vehicle concepts to be implemented quickly and helps car manufacturers to further increase their development efficiency. Start-ups are given the expertise to build an electric car. Customers can choose between a complete solution and pre-integrated modules.

Step one: functional integration

For a pre-integrated module, Bosch combines individual components such as the e-axle, braking system, steering system and control unit – the so-called Advanced Driving Module. To do so, interfaces are simplified and communication between the components is optimized. This ensures optimum interaction in the electric vehicle, for example regarding vehicle stabilization or recuperation.

Step two: mechanical integration

In cooperation with Benteler, the Bosch components are also mechanically assembled to form an axle module for the front and rear axles. Such a module is optimized in terms of construction space, among other things it improves damping and driving dynamics and can be used flexibly in different variants.

Step three: the fully integrated rolling chassis

The rolling chassis is the highest expansion stage and shows what a maximum of integration is possible. It includes all the necessary Bosch e-components up to an ingenious thermal management.


In the future, Bosch intends to integrate its module solutions into chassis in cooperation with partners and thus offer customers a complete rolling chassis. However, Bosch does not build vehicles and does not intend to do so in future. The aim is to support customers in driving forward e-mobility solutions more quickly. For pre-integrated modules and rolling chassis, Bosch sees a market potential in an amount of billions, mainly in China and North America, but also in Europe. The first customer projects have already been launched.

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.
