Abstract

A device installed in a vehicle for recording information on the itinerary of the vehicle. The device includes a receiver system for receiving wirelessly transmitted information for identifying the current geographical position of the vehicle, a computer unit for computing digitalized data on the geographical position of the vehicle, and a memory unit for continuous storage of the digitalized geographical position data of the vehicle on a data carrier, which is protected against overwriting of recorded data, whereby the memory device also stores time data, which allow identification of the particular point in time at which a particular vehicle position was found. So that an itinerary taken by a vehicle can later be reconstructed without great expense the data carrier is configured to be easily exchangeable, and a data reading device is provided for the input of data that identify the driver of the vehicle and are recorded on the data carrier.
