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.

Method for determining whether a motor vehicle has driven on a road included in digital map material

A method determines a weather area for a motor vehicle, with which a sensor system and a communications interface are associated, which are coupled to one another via signals. The method includes: receiving data including geographical information in the form of a map; and creating a grid by dividing the received data into a plurality of adjacent grid cells. The method also includes: providing a measurement signal of the sensor system, representing a location-related local weather situation in one of the grid cells; and determining a local weather area for the respective grid cell according to the provided measurement signal.

Method, device, and system for determining a weather area

A method of determining a first route on a first map based on a second route on a second map, comprising the steps of determining second points on the second map, the second points being included in the second route; determining first points on the first map; wherein the first points correspond in pairs to second points; and determining the first route comprising the first points by means of trace matching with respect to the second route.
