The demands on the electric and electronic systems
(E/E systems) in modern vehicles are rising steadily. As the number of systems in the on-board network continues to grow, the increasing exchange of data through vehicle connectivity must also be managed reliably.
Bosch Engineering’s development services for
E/E systems not only help fulfill the highest safety requirements, but they also contribute to the powertrain’s efficiency and the comfort of today’s vehicles.
Furthermore, they create a basis for additional, innovative features, such as remote diagnostics and software updates over the air.
E/E systems make it possible to recover braking energy and to provide the internal combustion engine with electrical support
E/E systems play a critical role in the efficiency of electrified powertrains. For example, connecting the powertrain to the navigation system enables intelligent energy management. Based on the route calculated, it determines the optimum battery charge and also gauges when the internal-combustion engine needs to be
supplied with additional torque from the electric motor when driving uphill. Recuperation – brake energy for free – can be applied most effectively during the following downhill stretches. This is how E/E systems and energy management help save fuel, maximize range, and reduce emissions.

Enhanced safety and comfort
E/E systems ensure that safety systems are always ready for action
A demand-based and fail-safe energy distribution supplies all safety-relevant components with power – including the ESP® at the decisive moment. For instance, during overtaking maneuvers on icy streets, the power supplied to consumers that provide comfort and are not safety-critical is temporarily suspended in order to guarantee ESP® function. Once the ESP® has been actively engaged and the overtaking maneuver is complete, those consumers are turned on again. The driver and passengers are unaware of the brief interruption and remain safe and comfortable the whole time. This is how E/E systems play a major role in vehicle safety.
safety comes first
Even when the vehicle electronics are being used intensively, safety-relevant functions such as ESP®
or ABS always remain operational.
protection against external access
The vehicle electronics are effectively safeguarded against unauthorized access by hackers.
Smart energy management ensures that all
comfort functions are provided without loss of
Innovative extra functions
Connected E/E systems make remote diagnostics and
software updates possible
Modern E/E systems facilitate the wireless connectivity of the vehicle with the outside world, which enables innovative additional features. For instance, connectivity software makes it possible to exchange data directly between the vehicle and the repair shop.
This saves time and optimizes processes; for example, by ordering spare parts before the car even arrives at the shop. Data can also be exchanged remotely with the manufacturer. This facilitates demand-based maintenance, a comprehensive portfolio of service offers, and optimization of manufacturing.

design of the E/E architecture in the same vehicle platforms.
The ability to remotely read out data can replace
trips to the workshop. ECUs can be reprogrammed via software-over-the-air technology.
