Method of navigating a vehicle (11) moving generally in one plane in which the actual position and direction (L) of the vehicle is determined by measuring the angles in said plane from a reference point of the vehicle (X, Y) to fixed points in relation to a reference direction on the vehicle. A plurality of points (X1Y1, X2Y2, X3Y3) anonymous but fixed as to the position thereof are arranged for the navigation, and the position of all the fixed points together with existing sight obstacles between the reference point of the vehicle and the fixed points are registered in an electronic memory. The movement of the vehicle in said plane is initiated in a known position and with a known direction for identifying the fixed points visible from the reference point in said position. In each position and direction of the vehicle during movement thereof the latest known position and direction are utilized in determining the identify of the fixed points visible at that moment.

Method of navigating a vehicle for instance an industrial truck moving generally in one plane by which a determination of the actual position and direction of the vehicle is provided by measuring the angles in said plane from a reference point on the vehicle to fixed points in relation to a reference direction of the vehicle at least three angles being used for a trigonometric determination by calculation means of position and direction, characterized in that a plurality of fixed points anonymous but determined as to the position thereof are arranged for the navigation, that the position for each of the points as well as existing sight obstacles between the reference point of the vehicle and the fixed points is stored in an electronic memory, that the movement of the vehicle in said plane is initiated in a known position and with a known direction so as to identify the fixed points visible from the reference point in said position, and that in each position and direction of the vehicle during the movement thereof, the latest known position and direction are utilized to determine with the aid of the stored position of the sight obstacles the identity of the fixed points visible at the moment.
