IoT device on wheels

The car is going to become an IoT device on wheels

Future vehicle development will be shaped by four megatrends: connectivity, personalization, powertrain electrification, and automated driving. Tomorrow’s car drivers will expect their vehicles to be fully integrated in their digital lives. The established boundaries between automotive electronics and consumer electronics will thus fade and disappear. The car is evolving into an IoT device on wheels in which new functions will be implemented primarily through software.

Bosch is setting the course for this transformation with new E/E architectures and vehicle computers

The megatrends electrified driving and automated driving will lead to a dramatic increase in functions, such as range optimization for electric vehicles and surroundings perception for driver assistance systems. Both of these developments are only to some extent realizable and manageable using classic electric/electronic (E/E) architectures. To manage the increasing complexity and connectivity, Bosch is working together with automobile manufacturers

to develop innovative E/E architectures in which new software solutions, powerful vehicle computers, and zone ECUs are integrated. With this, Bosch is already setting the appropriate course for future automotive developments that can meet the increased requirements of the megatrends and bring new vehicle functions onto the road safely, securely, and very economically.

“Vehicles have evolved into mobile computing centers. Even now, a vehicle contains some 100 million lines of software code. Only a company with wide-ranging electronics and software expertise will be in a position to shape the future of mobility.”

Software is the new innovation driver

Already since as far back as the 1970s, Bosch has been an important driver of innovation with the electronics-based solutions it has developed. One example is the ABS anti-lock braking system with which Bosch sparked the digital revolution in the automobile in 1978. Today, around 30,000 experts are involved in developing new software solutions, 14,000 of them in the mobility sector alone. With annual investments of more than three billion euros, Bosch is continuously strengthening its lead in expertise. After all, the amount of software, electronics, and control units in the vehicle is increasing at an ever-faster rate. Most new functions in the vehicle are now created based on software, such as in the areas of driver assistance systems, powertrains, and infotainment.

The functionalities range from real-time safety systems to interactive apps. The car is becoming a software-dominated system. The key is to reliably integrate all the software components and at the same time satisfy the very stringent safety requirements of the ASIL D standard (Automotive Safety Integrity Level D) – in combination with cybersecurity requirements. Bosch is a single-source supplier of vehicle electronics, sensor technologies, and software solutions that are designed to work perfectly with one another.

Furthermore, the on-board architecture and vehicle architecture can be expanded with cloud and backend solutions as well as services, enabling the vehicle to access and participate in mobility ecosystems and IoT.

The vehicle is evolving into an IoT device

User experience and personalization

Vehicles are becoming “IoT devices on wheels”. The services and user experience that end customers are used to having on their smartphones will also become available in the vehicle, i.e. personal infotainment apps. All this will be made possible with software that is constantly kept up to date.

E/E architecture

State-of-the-art E/E architecture is the heart of connectivity in the vehicle. With a vehicle-centralized, zone-oriented E/E architecture, Bosch is paving the way for new functions in the vehicle. It is based on only a few very powerful cross-domain vehicle computers.

Vehicle computers

In future, a few centralized, extremely powerful vehicle computers will be deployed to implement all of the vehicle functions instead of the one hundred and more control units that are needed today.

Connectivity with the cloud

With cloud connectivity, vehicle functions can be updated via over-the-air (OTA) software updates and new features can be installed. When it comes to the automotive cloud, Bosch is an innovation and industrial deployment partner as well as an integrator of diverse ecosystem providers.

Transition toward IoT

Vehicles will in future become IoT devices on wheels. The vehicle will be connected to drivers’ digital lives and will become their mobile assistant. It will also be possible to share data remotely with the vehicle manufacturer, e.g. for updates or on-demand service offerings.

Automated driving

Automated driving will result in a dramatic increase in functions coupled with growing complexity. Managing such scale is no longer possible using today’s E/E architectures. Significantly more computing power as well as new, clearly structured E/E architectures are required.

Electrification

The importance of software is growing also when it comes to controlling conventional vehicle functions like the powertrain. Examples of this are the energy-efficient combination of drive types in hybrid systems and the optimization of the battery range of electric drives via cloud-based services.

Bosch is building the E/E architecture of the future

With the continuous growth in electrification, new automated driving functions, and connectivity, the complexity of the vehicle’s electrical and electronic systems is increasing dramatically. To continue to meet the demands placed on the E/E architecture, Bosch is developing a vehicle-centralized, zone-oriented E/E architecture. It is based on a few very powerful cross-domain vehicle computers with lower-level zone ECUs as the hardware abstraction layer including Signal2Service translation. Thanks to its special functions, this new E/E architecture fulfills the most stringent safety standards. It is furthermore scalable and can be optimized for each individual automobile manufacturer. Bosch itself develops and manufactures many of the semiconductors needed for the control units.

Vehicle computers – increased computing power, lower costs, lower weight, less installation space needed

bosch_bbm_lt_vehicle_computer_vehicle_computers

Key elements of the innovative vehicle-centralized, zone-oriented architecture are the reorganization of the function partitioning and the optimization implemented in the E/E architecture. Instead of having a great many individual control units, there are only a few extremely powerful central computers – the vehicle computers. The company is already realizing such high-performance computers for automated driving, for the powertrain, and for the integration of infotainment systems and driver assistance functions. The vehicle computers are highly versatile and operate across all domains. Domain-specific software is no longer tied to a particular control unit but can be distributed flexibly to any cross-domain vehicle computer. They are therefore an important enabler for connected, zero-emission, and automated driving.

Semiconductors from Bosch

bosch_bbm_lt_vehicle_computer_semiconductors

Semiconductors are key components in electrical systems. In the E/E architecture, these tiny chips can be found in the sensor systems, data processing systems, and actuator systems of the vehicle, among other areas. They are therefore a part of the sensory organs and muscles of the system, so to speak. Bosch is one of the world’s leading chip manufacturers for mobility applications. Bosch is also developing special semiconductors to meet the forthcoming demand resulting from automated driving and electromobility. These include extremely efficient power semiconductors made from silicon carbide (SiC) for electric vehicle inverters as well as integrated circuits for particularly high-performance, cost-effective radar, lidar and video sensors for driver assistance systems. For systems that involve the use of artificial intelligence, Bosch is working on special, super-smart semiconductors. They shift computing operations from the software to the chip and thus reduce the energy required by the system.
