A method, a central control system and a non-transitory computer-readable storage medium are provided for determining driving assisting data in relation to a vehicle based on sensor data and map data in relation to other vehicles. Sensor data are obtained from a sensor system of a first vehicle, the sensor data comprising a pose and a velocity of a second vehicle located in a surrounding environment of the first vehicle. Furthermore, map data are obtained comprising a road geometry of the surrounding environment of the first vehicle. The pose and the velocity of the second vehicle are compared with the map data, and driving assisting data in relation to a third vehicle are determined based on the comparison.

Method and system for determining driving assisting data

Described herein is a method and arrangement () for sourcing of location information, generating and updating maps () representing the location. From at least two road vehicle () passages at the location is obtained () vehicle registered data on the surrounding environment from environment sensors and positioning data from consumer-grade satellite positioning arrangements and from at least one of an inertial measurement unit and a wheel speed sensor. The positioning data is smoothed () to establish continuous trajectories for the respective vehicles (). Individual surrounding environment maps are created using the data from each respective vehicle () passage at the location. From the individual surrounding environment maps are identified submaps () sharing area segments. Pairs of submaps () sharing area segments are cross-correlated (). The information from the pairwise cross-correlation () of submaps () is used for optimizing each submaps () offset relative a full map () of the surrounding environment and the submaps () are merged into the full map ().
