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. It generated sales of 52.6 billion euros in 2022, and thus contributed almost 60 percent of total sales. This makes the Bosch Group one of the leading automotive suppliers. The Mobility business sector 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 injection technology and powertrain peripherals for internal-combustion engines, diverse solutions for powertrain electrification, vehicle safety systems, driver-assistance and automated functions, technology for user-friendly infotainment as well as vehicle-to-vehicle and vehicle-to-infrastructure communication, repair-shop concepts, and 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 421,000 associates worldwide (as of December 31, 2022). The company generated sales of 88.2 billion euros in 2022. Its operations are divided into four business sectors: Mobility, Industrial Technology, Consumer Goods, and Energy and Building Technology. As a leading IoT provider, Bosch offers innovative solutions for smart homes, Industry 4.0, and connected mobility. Bosch is pursuing a vision of mobility that is sustainable, safe, and exciting. It uses its expertise in sensor technology, software, and services, as well as its own IoT cloud, to offer its customers connected, cross-domain solutions from a single source. The Bosch Group’s strategic objective is to facilitate connected living with products and solutions that either contain artificial intelligence (AI) or have been developed or manufactured with its help. Bosch improves quality of life worldwide with products and services that are innovative and spark enthusiasm. In short, Bosch creates technology that is “Invented for life.” 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. The basis for the company’s future growth is its innovative strength. At 136 locations across the globe, Bosch employs some 85,500 associates in research and development, of which nearly 44,000 are software engineers.
