Definitions

  • the invention relates to a motor vehicle-specific adapter according to the preamble of claim 1, a system with an adapter and an OBD socket or an OBD plug according to the preamble of claim 7 and a system with an adapter and a service diagnostic device.
  • the service diagnostic device is connected by means of a cable to the vehicle diagnostic bus, for example a CAN bus. Since the connection of the vehicle diagnostic bus is not standardized, it is often necessary to provide motor vehicle-specific adapter, which at one end to the diagnostic bus of the motor vehicle and the other end connected to the service diagnostic device OBD connector (on-board diagnostic connector ) are connectable. To ensure error-free operation of the service diagnostic device, the motor vehicle-specific adapter must be recognized by the service diagnostic device, i. H. be identified, for example, to correctly assign the data lines of the adapter and / or to address the on-board computer correctly.
  • OBD connector on-board diagnostic connector
  • the motor vehicle-specific adapters are equipped with one-wire chips, which can be read by the service diagnosis device.
  • the service diagnosis device As a result, almost any number of different motor vehicle-specific adapter can be coded.
  • the problem there is still the problem that always a signal line and a ground line for reading the one-wire chip are permanently occupied.
  • the invention has for its object to provide alternative means of identification, the use of which neither signal lines nor ground lines of the OBD cable are blocked. Furthermore, the object is to propose correspondingly improved systems.
  • the invention is based on the idea to send identification data (coding) for the identification of the motor vehicle-specific adapter via radio to the service diagnostic device.
  • the invention has recognized that this can be realized in a surprisingly simple manner by the provision of at least one RFID transmitter unit which is integrated or provided on and / or in a motor vehicle-specific adapter. Due to the wireless transmission of the identification data by means of an RFID transmitter unit is achieved with advantage that no signal line and no ground line of the OBD cable are occupied by the identification means. Furthermore, it is advantageous that negative influences on the vehicle diagnostic bus and / or the on-board computer, as can occur in the known resistance coding or in the provision of one-wire chips, are avoided by the provision of an RFID transmitter unit.
  • the means of the RFID transmission unit can be sent out identification data stored on one of the RFID transmitter unit associated memory, such as a flash memory.
  • the memory with the adapter-specific identification data is preferably an integral part of the RFID transmitter unit.
  • an embodiment of the motor vehicle-specific adapter is preferred in which the RFID transmitter unit as a so-called passive transmitting unit (transponder) is formed.
  • the energy to operate The RFID transmitter unit is thereby non-contact-coupled into the, in particular designed as a coil antenna, the RFID transmitter unit.
  • the RFID unit is designed as a so-called RFID tag.
  • the entire RFID transmitting unit which preferably also includes the electronic memory with the adapter-specific identification data, can be stuck onto the adapter from the outside. In the case of damage to the RFID transmitter unit, this can be easily replaced by sticking a new designed as an RFID tag RFID transmitter unit.
  • non-existing adapters can be easily retrofitted as an RFID tag due to the design of the RFID transmitter unit.
  • an embodiment of the adapter in which it has an OBD socket for connection to an OBD connector of the service diagnostic device and a vehicle-specific connector for direct connection to the vehicle diagnostic bus.
  • an embodiment is particularly preferred in which the OBD socket of the adapter and the vehicle-specific connector of the adapter are connected to each other via a cable.
  • the RFID reader unit is assigned directly to the OBD socket of the adapter is.
  • Prefers the RFID transmitter unit is located on the outside of the OBD socket which cooperates with the OBD connector of the service diagnostic device.
  • the invention also leads to a system with a previously described motor vehicle-specific adapter which can be connected to a service diagnostic device by means of an OBD cable having an OBD socket or an OBD plug. It is within the scope of the invention to permanently connect the OBD cable to the service diagnosis device, or else to design it in such a way that it can be detachably connected to the service diagnosis device, in particular by means of a plug connection.
  • the identification data of the motor vehicle-specific adapter at least one component of an RFID reading unit is assigned to the OBD cable and / or the OBD socket and / or the OBD plug.
  • the entire RFID reading unit is arranged on the OBD cable and / or on the OBD socket or on the OBD plug.
  • the electronic part and the RF part are signal-conducting connected to each other via at least one control line, which as a component, d. H. as an addition, the OBD cable can be formed.
  • the invention leads to a system with a previously described motor vehicle-specific adapter and with a service diagnostic device.
  • the service diagnostic device To the identification data of the motor vehicle-specific adapter, the service diagnostic device at least one component of an RFID reading unit, preferably the entire RFID reading unit assigned.
  • the service diagnostic device has only the electronic, ie digital part, the RFID reader unit and the RF part, in particular the antenna, arranged on an OBD socket or an OBD connector is, which is connectable to the motor vehicle-specific adapter, in particular with an OBD connector or an OBD socket of the adapter.
  • Fig. 1 is a system 1 comprising a service diagnostic device 2 designed for the workshop and a motor vehicle-specific adapter 3 for connecting the service diagnostic device 2 to an on-board computer of a motor vehicle, in particular a vehicle diagnostic bus (eg CAN) , shown.
  • a vehicle diagnostic bus eg CAN
  • the motor vehicle-specific adapter 3 comprises a 16-pin OBD socket 4, which is connected via a cable 5 with a motor vehicle-specific connector 6.
  • the motor vehicle-specific connector 6 is used for direct contacting of a form-congruent socket of the vehicle diagnostic system (not shown).
  • the service diagnostic device 2 has a sub-D plug 7 which can be coupled to a sub-D socket 8.
  • the sub-D socket 8 is connected via diagnostic lines 9 with an OBD connector 10.
  • the OBD plug 10 has sixteen diagnostic pins with which it can be coupled to the OBD socket of the motor vehicle-specific adapter 3.
  • the OBD connector 10 has an RFID reading unit 11, which is designed for contactless coupling of energy into an RFID transmission unit 12.
  • the RFID transmitting unit 12 is designed as an RFID tag and glued to the OBD socket 4 of the motor vehicle-specific adapter 3.
  • the RFID transmission unit 12 comprises a memory 13 in which adapter-specific identification data (coding) are stored.
  • the RFID transmitting unit 12 comprises an antenna, not shown, for receiving the energy emitted by the RFID reading unit 11.
  • the memory 13 of the RFID transmitting unit 12 can be read out.
  • the read-out identification data are transmitted from the RFID reading unit 11 to a logic unit of the service diagnostic device 2.
  • the logic unit or a cooperating with this software assigns the read identification data to a specific motor vehicle-specific adapter 3 and thus allows trouble-free reading of the vehicle on-board computer.
