PCT No. PCT/DE93/00094 Sec. 371 Date Oct. 22, 1993 Sec. 102(e) Date Oct. 22, 1993 PCT Filed Feb. 4, 1993 PCT Pub. No. WO93/17406 PCT Pub. Date Sep. 2, 1993.A navigation device for land vehicles, particularly for passenger cars and trucks, is proposed which has a storage for geographical data, sensors for detecting actual travel data, a comparison device, and an information delivery device. The navigation device is characterized by the fact that the limit speed (vi) safe for travel over the path of travel is determined in a calculating unit (9) from the geographical data concerning the course of the path of the travel and is compared with the instantaneous speed of the vehicle. When the limit speed is exceeded in positive or negative direction, an information delivery device (11) is activated and possibly also a conversion device (13), they acting on setting members, for instance brakes or engine control of the vehicle.
