Volvo tests road magnets to help position self-driving cars
Volvo is researching the use of road magnets to help position autonomous vehicles.
We have tested the technology at a variety of speeds and the results so far are promising, said Jonas Ekmark, preventive safety leader at Volvo Car Group.
Reliable and highly accurate positioning is one of the crucial issues in the development of self-driving cars. Magnets are unaffected by physical obstacles and poor weather conditions.
The car in the test was equipped with several magnetic field sensors.
The next step is to conduct tests in real-life traffic, said Ekmark.
Other possible uses for the magnets:
Incorporating magnet-based positioning in preventive safety systems could help prevent cars from running off the road.
Magnets could improve the accuracy of winter road maintenance and prevent damage of snow-covered objects near the edge of the road.
Accurate positioning of cars could allow lanes to be narrower.Download Bulletin PDF
