Abstract
A method and system for stopping an unmanned mine vehicle in a predetermined position. The mine vehicle is driven at a low speed towards a physical. When the mine vehicle encounters the obstacle (7, 7a, 7b), a speed difference greater than a predetermined limit value is generated between the speed of the mine vehicle and the driving power transmission. The control system of the mine vehicle detects the exceeding of the limit value and stops the vehicle.
