Bosch and Daimler are speeding up the development of fully-automated and driverless driving (SAE Level 4/5) in the city and are decisively setting the course. The partners have chosen California as the pilot location for the first test fleet.
In the second half of 2019, Bosch and Daimler will offer customers a shuttle service with automated vehicles on selected routes in a Californian metropolis. Daimler Mobility Services is envisaged as the operator of this test fleet and the app-based mobility service. The pilot project will demonstrate how mobility services such as car sharing (car2go), ride-hailing (mytaxi) and multi-modal platforms (moovel) can be intelligently connected to shape the future of mobility. In addition, the partners have decided on the US technology company Nvidia as the supplier of the artificial intelligence platform as part of their control unit network.
For the joint development of a driving system for fully-automated and driverless vehicles, Bosch and Daimler rely on their automotive expertise accumulated over many decades to bring mature and safe innovations to market.
Evaluation of sensor data within milliseconds
A decisive factor for fully-automated and driverless driving in an urban environment is the reliable recognition of the vehicle’s surroundings with the aid of various sensors. Analysing and interpreting the variety of incoming data and translating them into driving commands within a very short time requires enormous computing power – the fully-automated, driverless vehicle will be a mobile super-computer. At the same time, fully-automated, driverless driving in the city requires a versatile, redundant systems architecture and the highest level of functional safety. To achieve this level of safety, the necessary computing operations are performed in parallel in different circuits. This means that the system has instant recourse to these parallel computing results when necessary.
For their driving system, Bosch and Daimler thus rely on a control unit network made up of several individual control units. The US technology company Nvidia supplies the platform required for this, which can run the Artificial Intelligence (AI) algorithms generated by Bosch and Daimler for the vehicle’s movement.
The network of control units collates the data from all sensors with radar, video, lidar and ultrasound technology (sensor data fusion), evaluates them within milliseconds and plans the movements of the vehicle. All in all, the control unit network has a computing capacity of hundreds of trillion operations per second. That’s as much as several S‑Class vehicles together could reach just a few years ago.
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.
Metropolis in California will be a pilot city for automated test fleet
The control unit network will also be used in the fleet vehicles which Daimler and Bosch will put on the roads of California in the second half of 2019. Not only that: Both partners will offer customers an automated shuttle service on select routes in a city located in the San Francisco Bay in Silicon Valley. The test operation will provide information about how fully-automated and driverless vehicles can be integrated into a multi-modal transport network. Many cities face numerous challenges that are increasingly burdening the existing transport system. The test is to show how this new technology might be a solution to these challenges.
Driverless driving makes urban mobility more attractive
With their development cooperation on fully-automated and driverless driving in urban environments which began in April 2017, Bosch and Daimler aim to improve the flow of traffic in cities, enhance safety on the road and provide an important building block for the way traffic will work in the future. The technology will, among other things, boost the attraction of car sharing. In addition, it will allow people to make the best possible use of their time in the vehicle, and open up new mobility opportunities for people without a driver’s licence, for example.
The vehicle comes to the driver, not the driver to the vehicle. Within a defined city area, users can conveniently order a car-sharing car or a vehicle that drives by without a driver. The project especially combines the overall vehicle and mobility expertise of one of the world’s leading premium manufacturer with the systems and hardware expertise of one of the world’s largest suppliers. The ensuing synergies’ purpose is to introduce the new technology early and fully validated.
