Bosch & TomTom Use Sensors To Develop Maps for Automated Vehicles

By Editorial Team on June 21, 2017

Bosch & Tomtom have come together to develop high-resolution road maps for automated driving. Called “radar road signature”, the system is composed of billions of individual reflection points and will enable automatic vehicles to accurately determine their locations.

Unlike maps that uniquely rely on video data for vehicle localization but the radar road signature will function reliably at night and in conditions of poor visibility. “We are delighted to be able to introduce supplemental localization data in the form of the radar road signature in partnership with Bosch. It will make self-localization for automated vehicles considerably more robust in every respect,” says TomTom’s CEO Harold Goddijn.

High-resolution maps are crucial for automated cars and provide information that cannot be monitored by sensors. They contained 3 different overlapping layers: a localization layer, a planning layer and a dynamic layers. Those layers enable automated cars to determine their position in a lane, identify traffic signs and speed limits and receive information about sudden changing traffic situations like traffic jams.

Both companies expect to operate the radar road signature by 2020 at the latest in Europe and the United States.
