vehicles are complex computers on wheels. And they need even more computing power if they are to negotiate city traffic automatically, with input sourced from an array of disparate surround sensors.

In their alliance to put highly automated and driverless vehicles on urban streets, and have specified the computing power needed for their prospective system. The two companies have selected and signed an agreement with the U.S. computing company as a supplier for the artificial intelligence (AI) they need. AI is an important building block in fully automated and driverless vehicles´ network of several individual ECUs (Electronic control units). Under this contract, will provide its platform powered by high performance AI automotive processors along with system software that will process the vehicle- algorithms generated by Bosch and Daimler using machine-learning methods. As a result, the ECU network will reach a computing capacity of hundreds of trillion operations per second. This is akin to the performance delivered by at least six synchronized, highly advanced deskside computer workstations. Bosch and Daimler will also be able to tap ’s expertise to help develop the platform.

Sensor data processed within fractions of a second


A versatile, redundant, and fail-operational systems architecture is needed to make automated driving in a reality. The performance bar for the networked ECUs is no lower, as navigating city traffic is a tremendous amount of work. This network handles all the information gathered and transmitted by disparate radar, video, lidar, and ultrasonic sensors. Just one video sensor, such as Bosch’s stereo video camera, generates 100 gigabytes of data in just one kilometer. The ECU network combines data sourced from all the surround sensors in a process called sensor fusion. Within fractions of a second, it assesses this information and plans the trajectory of the vehicle. This is as fast as the sensation of touch that needs between 20 and 500 milliseconds to reach the human brain. Bosch and Daimler bring many years of experience to the development of functional safety systems. To achieve maximum safety and reliability, the necessary computing operations are done by a number of circuits in parallel. In the unlikely event of a malfunction, the results of these parallel calculations can be accessed in a flash.

ECU network to be integrated into battery cells’ cooling circuit

The high computing capacity and the huge number of operations to be performed mean that the ECU network needs to be cooled. Bosch and Daimler developed an efficient concept based on liquid cooling. In this jointly developed system for highly automated and driverless driving in cities, Mercedes-Benz intends to deploy battery-powered vehicles. These cars have a cooling system on board, so engineers can make the most of this legacy technology by integrating the ECU network into the battery cells’ advanced cooling circuit.

Bosch and Daimler staff working side by side

In April 2017, Bosch and Daimler announced they would be joining forces in an effort to put highly automated and driverless vehicles on city streets. This alliance is developing a driving system for use in vehicles that will be able to maneuver through city traffic driverlessly. The technology is to be ramped up for mass production by the beginning of the next decade. Bosch and Daimler are working together in the greater Stuttgart area and in Silicon Valley. The two companies’ personnel are co-located, working practically at adjacent desks. This allows them to quickly and efficiently share information across disciplines and to make decisions fast.
