TomTom and Bosch have announced the creation of an HD map with integrated Radar Road Signature layer for the localisation of vehicles in autonomous driving. The Radar Road Signature layer will allow automated vehicles to determine their exact location on a road down to a few centimeters, working in conjunction with the TomTom HD Map.
The advantage of the Bosch Radar Road Signature map is its robustness: unlike maps that rely exclusively on video data for vehicle localisation, the Radar Road Signature can be used and generated reliably at night and in conditions of poor visibility. The Bosch Radar Road Signature only needs to transmit five kilobytes of data to a cloud per kilometre, which is half the bandwidth necessary for video-based mapping.
Bosch wants to launch the Radar Road Signature onto the market in Europe and the U.S. by 2020 at the latest.
