Abstract
Methods, systems, and electronic control units are provided. It is determined whether a motor vehicle has driven on a road included in digital map material. First absolute position data is captured relating to the motor vehicle using an absolute positioning system and capturing first vehicle odometry data using an odometry system of the motor vehicle at a first point in time during operation of the motor vehicle. Further absolute position data is captured relating to the motor vehicle using the absolute positioning system and capturing further vehicle odometry data using the odometry system at one further point in time during operation of the motor vehicle which differs from the first point in time. It is determined whether the motor vehicle has driven on a road included in digital map material based on the digital map material, the captured data, and a map-matching algorithm.
