Precise data for greater safety: Audi warns its drivers faster about slippery roads

Since 2017, cars made by Audi have been able to warn each other about accidents, broken down vehicles, traffic jams, road ice, or limited visibility, a communication technology known as ‘car to X’. It analyzes various data for Local Hazard Information, including activation of Electronic Stabilization Control (ESC), rain and light sensors, windshield wipers, headlights, emergency calls, and airbag triggers. Audi is now taking the next step by improving the service with high-precision swarm data to make the warning even faster and more precise. The brand with the four rings is the first manufacturer to use a patented solution from Swedish company NIRA Dynamics AB for this purpose. The two companies adapted this solution as a basis to develop the enhanced hazard alerts together with the Car.Software organization and HERE Technologies.

The sensor data is anonymized, both in the car itself and when transmitted to the cloud hosted by NIRA Dynamics AB. Aggregated data from many vehicles are then combined with metadata, such as current and historical weather information, and then transmitted by NIRA cloud to service provider HERE Technologies.

Coming back to the vehicle, HERE servers send the warning information to those cars that are in or heading toward areas with poor conditions.

Number of vehicles involved is a key success factor

The greater the number of vehicles that deliver the data, the better the system can learn, analyze, and create maps, and thereby inform or warn the drivers depending on the situation. . In 2021, more than 1.7 million vehicles from the Volkswagen Group in Europe will contribute data for this improved hazard information service, and this will increase to more than 3 million in 2022, creating a significant competitive advantage.

The Car.Software organization, a company of the Volkswagen Group, took the main responsibility for development. The project for improved hazard information is a good example of the great potential of cross-brand software development. Together with other Group brands and our strategic partners, we were able to develop a digital service within a few months while making use of our own software skills and economies of scale, says Thomas Müller, Head of Advanced Driving Assistance Systems ADAS & Automated Driving AD at the Car.Software organization. “The improved hazard information service is just the beginning; we see wide-ranging potential for the future.”
