ADAS combined with digital mapping provides drivers with significant fuel savings. That’s the conclusion of tests conducted on public roads by Delphi Technologies and TomTom. Tests combining Delphi’s ADAS with TomTom’s ADAS Map show fuel savings of more than 10 percent in passenger cars.

The proof of concept used a Delphi Technologies’ Intelligent Driving prototype vehicle equipped with its latest propulsion software and TomTom’s ADAS map.

Testing involved a range of routes to validate the system’s fuel economy benefits under a variety of real-world driving conditions.

Results show that powertrain efficiency improved when TomTom’s ADAS map was activated. Conducted with different drivers who selected their preferred routes, the testing also demonstrated the system’s adaptability and capacity to deliver results without compromising the driving experience or extending driving times.

The TomTom ADAS Map provides enriched accurate data on speed limits, lane information, gradient, road curvature and traffic signs. Delphi Technologies’ Intelligent Driving software suite uses the TomTom data to anticipate the road ahead, optimising the car’s propulsion system for improved speed and control for reduced energy consumption.

“The TomTom ADAS Map is a tried, tested and proven technology, assisting over 1.5 million automated vehicles’ driving safety and comfort around the world today,” said Willem Strijbosch, Head of Autonomous Driving at TomTom. “Our collaboration with Delphi Technologies shows that the latest generation of our high-quality ADAS technology can dramatically reduce running costs by reducing fuel consumption.”

“The significant efficiency gains from our collaboration with TomTom demonstrate how our proprietary Intelligent Driving system, combined with the right, high-fidelity mapping data, can enable everyday vehicles to drive cleaner, better and further, without compromises,” said Paul Farrell, senior vice president, Strategy and Corporate Development, Delphi Technologies. “We have an exciting solution backed by real-world data that our customers can use today – and tomorrow – to provide tangible, real-world benefits.”
