20080251577 | Assembly Comprising a Tachograph - An assembly has a tachograph and a data memory, in particular a data memory of a data card. The tachograph has an interface designed to exchange data between the tachograph and the data memory, logic function modules and at least one memory. In a method for operating the tachograph, as a result of high security requirements, the data transfer between the data memory and the tachograph is extremely time-intensive. At the start of the data transfer a virtual reproduction of the data memory is created in the memory of the tachograph and the logic function modules first have read and write access to the virtual reproduction in the memory. Data is then regularly written to the data memory of the data card by a write access to the memory, thus eliminating the differences between the virtual reproduction and the data memory. | 10-16-2008 |
20080262674 | Data Processing Arrangement and the Operation Mode Thereof - A data processing arrangement, in particular a tachograph for a motor vehicle has a control device and at least one memory. The traceability of an error arising during the data processing arrangement operation can be better guaranteed. At least one partial area of the memory is embodied in the form of a sequence memory and a control device is constructed such that sequences of the data processing arrangement or of the tachograph are recorded in the sequence memory, wherein the sequence memory is provided with at least one ring memory which is organised such that an oldest input is overwritten by a new input, respectively. Thus, it is made possible to record a plurality of sequential events leading to a substantial error in the sequence memory such that the size of the memory is increased within economically acceptable limits during a long operation of the arrangement. | 10-23-2008 |

20110099314 | Method for Operating a Trip Recorder of a Motor Vehicle and a Trip Recorder for Performing the Method - A trip recorder, a memory card or a cleaning card being passed by a reading device by an electric motor drive. The trip recorder attempts to establish communication with the inserted card. If no communication can be established, the reader device or the memory card is dirty, or the cleaning card is inserted in the trip recorder. In case of a failed attempt at communication, the electric motor drive moves the inserted card past the reader device repeatedly removing potential contamination. | 04-28-2011 |
