FEV accelerates development time for Autonomous Driving with Microsoft Azure

News

Automated driving functions and autonomous driving fundamentally influence the way we will move in future.

Validating these functions require systems that recognise the various scenarios in road traffic during test drives, evaluate them, and prepare them for the developers. The global vehicle developer, FEV, is overcoming this central challenge with a data management and assessment system developed in house, which uses the computing power of Microsoft's cloud platform Azure. The system was presented at the IAA.

By today's estimates, test scopes of 240 million to 16 billion kilometres of road are needed to validate an automated driving function. However, it is not the quantity of tests that determines the maturity of a system, but the number of road traffic situations “experienced” in which the algorithms have to actively make a decision - for example, during an overtaking maneuver on the highway.

In this regard, the V2I (Vehicle-to-Infrastructure) data management system established by FEV is an efficient solution for the development and validation of such driving functions. This is because aside from the duration and number of test drives, the quantities of data obtained are also a major challenge with regard to the validation. The sensor set installed in the vehicle, consisting of cameras, lidar (light detection and ranging), and radar (radio detection and ranging), quickly generates up to 40 terabytes of data in a single day.

That is precisely what the data management solution from FEV deals with. First, a networked data logger developed in-house takes over the collection of selected vehicle signals and sends them to a back-end in real time during the test drive. With Microsoft Azure and Azure IoT Hub transferring the data, FEV was able to build on an established, high-performance, highly secure cloud platform. The sent vehicle data is consolidated in the cloud, while algorithms analyse these signals in regards to relevant scenarios. It is therefore possible to send feedback to the relevant engineers even during test drives, and to flexibly coordinate entire fleets according to a predefined plan.

A standardised time stamp also significantly simplifies the cleaning and preparation of all vehicle data. Not least, this scenario-based pre-filtering also enables cost-efficient data storage in the cloud. Only previously-detected data packets or scenarios are loaded into the cloud hot storage, which is the layer with the highest available computing power and access management. Less important sections are saved in lower performance cloud areas that are consequently more affordable.

As an integration and development partner in series production projects of various automotive manufacturers, the efficient assessment and validation of sensor data quickly proved its worth for FEV and its clients. To minimise the general testing time on real streets and the associated costs, the development service provider is increasingly transferring significant test scopes to simulation and laboratory environments.

According to Professor Stefan Pischinger, President & CEO of the FEV Group, these plans are moving ahead: “The data-logger solution, in combination with FEV's own cloud-based labeling software, is a significant milestone for the construction of a holistic development environment for ADAS/AD environments. The efficient preparation of the data using automated recognition and classification according to driving situation is the basis for all other process steps in this regard.”

While the driver assistance systems in series production today are still based on predefined rules, in the future, FEV believes that this will also be possible with the use of machine learning. “Our goal will only have been reached when artificial intelligence can handle even the most complex of situations and accurately anticipate the behavior of road users,” said Professor Pischinger.

The collaboration with Microsoft is an important component of this. Interdisciplinary collaboration between sections of the automotive industry and IT is enabling groundbreaking, cross-company innovations to be established, which offer significant advantages in the development process.
