Supplementary information material on the connectivity solutions offered by Bosch

The impacts of urbanization are clearly apparent in our society. But more people in urban areas also means more environmental pollution, more noise, and more time lost in traffic. In an effort to counteract all of these negative aspects, Bosch is continually driving the development of connected solutions for vehicles, whereby connection with the cloud and the surroundings plays a significant role. This not only makes it possible to use the internet of things; it also makes a considerable contribution toward safety on the road. Via communication with the cloud or by screening their surroundings, vehicles can detect risks at an early stage and take the appropriate countermeasures to avoid them. But that is not all: communication between vehicles also ensures significantly more safety and improves the flow of traffic.

With cloud-based services and the internet of things, Bosch creates new opportunities and mobility offers such as automated driving. Numerous technical modules form the basis for these services and ensure secure connections inside the vehicle and with its surroundings.

Technical enablers – what they are and how they are changing our future

Automated driving, connected services, and vehicles that communicate with each other – the future seems within reach. But in order to use these services, a reliable technical basis is required. This basis is provided by so-called technical drivers or enablers which make it possible to connect vehicles in the first place. Some of them, like updates over the air or V2X connectivity, form the basis for connected driving. High-performance sensors, such as cameras, radar systems covering various ranges, and lidars, ensure that passenger cars, trucks, and other types of vehicles will be able to perceive their surroundings very reliably in the future. Vehicle computer solutions combined with the vehicle runtime environment (VRTE) make the high-performance computing infrastructure available which is required for automated driving and connected services.

But interplay by both is what is decisive: the proper and secure flow of communication and the requisite processing power inside the vehicles ensures that signals perceived from their surroundings can be received and processed. The information received is then forwarded to the appropriate recipient with the corresponding commands and implemented as required. A process which is essential for automated driving in particular. Only then will vehicles be capable of making autonomous decisions in complex traffic situations in the future.

This is how technical enablers safeguard future mobility, making them an indispensable part of the automotive industry of tomorrow.

Connectivity solutions offered by Bosch inside the vehicle and with its surroundings

Connectivity inside the vehicle

Future mobility is all about connected mobility. It lays the foundation for connected services and automated driving. Numerous technical enablers are required to implement these services and functions in the future, whereby connectivity inside the vehicle itself is a key aspect. In-vehicle information and communication systems transform the vehicle into a central communication medium.

They ensure that internal and external signals are transmitted, received, forwarded, and processed.

Find out here what technical enablers are responsible for connectivity inside the vehicle and why they are essential for future mobility.

E/E architecture undergoing transformation

Lighter, more dynamic and flexible: E/E architecture is currently subject to a paradigm shift. Automated driving and connected services lead to a significant increase in functions within the E/E architecture. In order to safely master this complexity, there is a shift taking place from a domain-specific to a cross-domain and centralized structure in which some of the many individual control units are replaced with fewer but very powerful vehicle computers. In particular, the high demands on flexibility and scalability when embedding functions in the E/E architecture are key drivers for this change, which not only results in lower costs: thanks to perfect system design, shorter lines, and optimal integration, it is also possible to achieve extensive weight reductions.

Semiconductors for a connected future

Semiconductors from Bosch are integral in every vehicle

Semiconductors have been used in cars for several decades. These tiny chips are a key technology in the modern world and represent core components of electric systems. They are used to control the powertrain and driving behavior, specify directions in navigation, and tell the airbag when to release. Bosch is one of the world's leading chip manufacturers for mobility applications. Despite their long-standing history, semiconductors are one thing in particular: they are key to a successful future. These key components of modern mobility have become integral in every car. In 2016, every newly-registered vehicle worldwide had on average more than nine Bosch chips on board. When it comes to semiconductors for cars, Bosch makes the most of one unique advantage the company can offer: only Bosch is equally at home in the automotive and semiconductor industries. In 2018, every new vehicle included semiconductors to the value of 370 USD (source: ZVEI). And the demand for chips in cars will continue to rise in the years to come, thanks to increasing electrification and automation.
