Researchers at the VTT Technical Research Center in Finland have developed Martti, a self-driving vehicle designed to maneuver in rough and icy conditions.
The team says they created filtering technology for processing environment perception data and improving the performance of LiDAR in snowy conditions.
"In addition, the control strategy of driving this car has special features for controlling the vehicle when friction due to snow or ice makes driving conditions challenging," notes VTT's Matti Kutila.
Martti includes cameras, antennae, sensors, and laser scanners, and was created using a Volkswagen Touareg. The autonomous car's three laser scanners sense the environment in front of the vehicle, and a global-positioning system with correction signaling and an inertia unit helps align the car on the road.
The researchers tested Martii on a snow-covered road in Muonio, Finland, during which it reached a speed of 25 miles an hour, marking a major breakthrough for autonomous cars in rough conditions.
