  • Interface module can be integrated in the terminal or a Structural satellite navigation receiver with the terminal be summarized.
  • the terminal 1 is a terminal 1 with an antenna 2 intended.
  • the terminal 1 consists essentially of one Mobile station of a cellular network, for example after GSM standard. It has an interface 3, the data can be supplied as messages according to GSM standard can be transmitted.
  • the terminal 1 can be trained that it except for the transmission of data is also suitable for making calls. Furthermore, the Use of a terminal integrated in a car radio possible.
  • the interface 3 is in the embodiments Figures 1, 5 and 6 with a serial data line 4 an interface module 5 or 41 or 45 connected, the in the illustrated embodiments, inputs 6 to 12 has.
  • the number of inputs shown is just an example. Depending on your needs, more or fewer inputs are provided, the operating parameters and measured values - hereinafter also called sensor signals - are feedable.
  • the serial data line 4 can be used as the Motor vehicle construction imported CAN bus be formed what in the embodiments of Figures 3 and 4 of Case is.
  • FIG. 2 is an example of an interface module 23 a circuit shown, which consists essentially of a Microcomputer 14 and a CAN controller 15 exists.
  • the CAN controller 15 is connected to CAN bus 20 while 14 the sensor signals can be supplied to the microcomputer.
  • an input 24 an analog signal, for example one External thermometer, supplied via a signal converter 16 and an analog / digital converter 17 an input of Microcomputer 14 is fed.
  • the entrance will be 25 for example, a switching signal from a wiper fed, which only says whether the wiper is on or off.
  • the interface module 5 (FIG. 1) corresponds to essential the interface module 23 and therefore needs not to be explained again.
  • the microcomputer 14 with integrated data and Program memory controls the conversion of the sensor signals into CAN data frame and coordinates other internal processes.
  • Microcomputer 14 still further processing steps for the supplied sensor signals can be provided. So can for example by an individual, if necessary Programming can be preset what data to be transferred or released for transfer become.
  • filtering the sensor signals be carried out, in particular to increase the Meaningfulness or the security of the transmitted data. For example, from the position of the wiper switch rain may be inadvertent briefly switching on the wiper are ignored, that before transferring the corresponding data to several separate times of the wiper switches is queried.
  • Amount of data can be reduced, which can be important if a very large number of motor vehicles with devices according to the invention is provided.
  • a selection of the data to be transferred is also available depending on those added via the cellular network Instructions possible. This allows vehicles, for example be asked to send data that is in a given region in which this data for a Evaluation are interesting. So it doesn't make sense that Thousands of vehicles within an urban area Send out messages that their speed is a falls below predetermined threshold, while such Reports from vehicles traveling on a motorway Indication of a traffic jam.
  • the signal converters set those emitted by the sensors Voltages into values suitable for the microcomputer 14.
  • the means in the case of binary signals, the Output voltage of the signal converter immediately that Microcomputer 14 are supplied.
