Navigation aid for vehicles

Abstract

Abstract 1. A navigation method for a vehicle having vehicle navigation equipment containing a direction sensor and a displacement pick-up, which equipment determines the instantaneous position according to the dead-reckoning navigation method, having an indicator device for indicating the direction and the distance to the destination and having a map containing the starting point and the destination, wherein at the start of the journey the, at least approximate, starting and final destination co-ordinate data are fed into a computing circuit by scanning machine-readable markings applied to the map or to auxiliary means (film) associated with the map, and wherein in this computing circuit the direction and distance to the destination are continuously determined therefrom and from the actual location co-ordinates, characterised in that the co-ordinates of at least one intermediate destination (1, 2, 9, 11) are fed to the computing circuit (3, 4, 5, 6) wherein, until reaching the intermediate destination, the computing circuit determines in each case, the direction of the intermediate destination from the actual position coordinates determined by the vehicle navigation equipment and the co-ordinates of the intermediate destination, and indicates it on the indicator device, and in that a change-over device is provided which, on reaching the intermediate destination causes, in the computing circuit, the evaluation of the co-ordinates of the next intermediate destination or of the final destination for the formation of the new direction of the intermediate destination of the direction of the final destination.
