<p>1. Tachograph for motor vehicles in which data relating to the vehicle and its operation are undeletably recorded by a recording device (23, 24) on a time dependently driven diagram disk (42) and which for deletably recording selected data is provided with a data store (52) to which a microprocessor (50) is attributed for controlling the data input, characterized in that the results of data calculated with the said of the microprocessor (50) and/or event data selected by the program are stored over a time sector being the multiple of the time sector of the time dependently driven record carrier (42) are retained in the data store (52) that the diagram disk drive (V5 ) for recording the stored data may be switched over by the same recording device serving to the time dependent recording from the usual number of revolution of 1/24 h to an essentially higher number of revolutions and that the usual diagram disk serving to the time dependent recording is replaced by a special data diagram disk (42).</p> |
