- We also need to consider the different needs of lower levels of automated driving. In this case, we would need a less granular ADAS map that has larger coverage. This is perfectly suited for lower-level automation features such as adaptive cruise control (ACC).
Safer autonomous driving with proven technologies
TomTom was the first to launch HD maps in 2015, and many other companies have followed suit since then. However, map-making is a unique skill that requires decades of experience before it can be deployed on a global scale. In a future with millions of automated driving cars, we need a map that can process all that data and still ensure all these have access to the latest HD and ADAS maps.
With our industry-leading transactional map-making platform, TomTom is best positioned to enable safe autonomous driving with ADAS and HD Maps on a global scale. This brings us to the third principle of HD maps to combat safety issues concerning self-driving cars.
Reduce R2M time to increase autonomous driving safety
It’s important for HD maps to be constantly updated. Being able to reflect changes in reality on the map as soon as possible from the moment they happen is critical for accuracy and, ultimately, safety in a self-driving car.
Let’s take the example of a new traffic sign. Its existence should be reflected in the map as quickly as possible. This can be quantified as reality to map time (R2M). The shorter the R2M, the more accurate the HD map and therefore the safer it is for AD systems to rely on.
At TomTom, we strive to minimize R2M to maximize safety, as we have been doing for years with the industry-leading real-time TomTom Traffic service. With TomTom Traffic, we process hundreds of millions GPS data points to create an accurate representation of traffic density on the road, with cycles times of less than a minute.
HD maps for safe autonomous driving
For self-driving cars to be safe, HD maps should be complete, proven and fast. At TomTom, we are relentless in perfecting our HD and ADAS mapping technology. Stay tuned as we continue to announce exciting news and partnerships in 2020 and beyond.
