Abstract
A method of initializing the position and direction of a mining vehicle, and a mining vehicle. An environmental model and route points are stored in a control system of the vehicle. The environment of the vehicle is scanned, and scanned points are generated based on obstacles observed. The control system is arranged to determine coordinates of the scanned points by using the position of the route points within a search range and at least one direction. The coordinates calculated for the scanned points are compared with the environmental model. Such a route point and direction are selected as initial values for the mining vehicle, by which the generated coordinates of the scanned points best match the environmental model.
