Definitions

  • the invention relates to a device and a method for reproducing information in a motor vehicle according to the category of the independent claims.
  • a vehicle with a key is known from DE 196 480 42 AI. This key is used to identify the authorized user. In this
  • the key is data such as customer address, vehicle registration number, mileage etc.
  • the key is inserted into a reading device that is connected to a computer and has a key on its screen for reading out the key data
  • Dialogue is carried out. However, the display is only possible if a password is entered manually.
  • This arrangement is only suitable in connection with an external device for reading out data of interest.
  • the invention has for its object to provide a functionally enhanced display device for normal use of the vehicle. This object is solved by the features of the independent claims. Advantages of the invention
  • the device according to the invention for reproducing information in a motor vehicle comprises a (or more) portable transponder as part of a keyless entry and / or driver authorization system which sends a code to a control device arranged in the motor vehicle. Access and / or driving authorization is granted when the control unit receives a valid code. It comprises a display which is arranged in the motor vehicle. The display shows certain data depending on an output signal from the control unit.
  • the display can only be activated if one of the
  • Transponder sent valid code was detected.
  • the data of interest is only available to users who identify themselves as authorized. Other people who are not in possession of a valid transponder are denied access to this data.
  • the display can be updated automatically on the basis of the code received, without the need for further operating signals from the user.
  • the code signal of a transponder is therefore suitable for this initiation process of the display, since the transmission process of the code signal takes place before the start of the motor vehicle. The user can thus obtain information in advance about the operating states of interest of the motor vehicle before actuating the ignition.
  • the code signal of a transponder is triggered automatically when the outside door handle, the ignition / start switch and, if available, the remote control button of the transponder are activated.
  • the data are also displayed when another Control element, a door contact, was actuated.
  • the combination of the transponder query with an output signal of an operating element ensures security against unauthorized access to the data, on the one hand, and the display only occurs at the time when the actuation of an operating element indicates that the user is in the passenger compartment.
  • a further embodiment displays data which depend directly on the code received by the control device.
  • the control unit sends out a search signal which addresses all the transponders assigned to the vehicle.
  • the transponders within the transmission range of the control unit send back a corresponding response signal.
  • the control unit can use the incoming signals to identify which transponders are present. This information is passed on to the advertisement.
  • the display duration is preferably limited to a predetermined time. This ensures that, as a rule, no operator intervention is required to support the function of the solution according to the invention.
  • the current display duration is extended by a further full basic time period if a further trigger event occurs before the specified display time has expired.
  • the display duration can also be linked to the arrival of another event. This event can be starting and / or stopping the engine or closing the vehicle.
  • the method according to the invention for reproducing information in a motor vehicle has a portable transponder as part of a keyless access and / or driving authorization system which is connected to a system in which
  • Control unit arranged in the motor vehicle sends a code via a transmitter / receiver, wherein access and / or driving authorization is granted if the control unit receives a valid code.
  • a display is arranged in the motor vehicle, the display displaying certain data as a function of an output signal from the control unit. The process is characterized by the following steps -.
  • the data exchange carried out in connection with the authorization query provides information as to which transponders are in the detection area of the transmitter / receiver. This information is fed to the display in the subsequent step and is immediately available to the user.
  • the display is activated even if no code or an unauthorized code is received within a period of time starting with the transmission of the search signal. The user can be made aware of this critical situation immediately, since the corresponding query procedure for transponder recognition has already been carried out. Further expedient further developments result from further dependent claims and from the description.

  • the control unit 10 communicates via a bus system 18 with a display unit 24, which comprises a display 26.
  • a signal from a door switch 20 is fed to the bus system 18, as is a signal from an operating element 22.
  • a diagnostic interface 28 is provided on the bus system 18, via which data can be read in or read out in connection with an input / output unit 30.
  • the corresponding signal change is evaluated by the control unit 10.
  • the transmitter / receiver 14 of the control unit 10 then issues a search signal.
  • the first transponder T1 located within the range of the transmitter / receiver 14 sends a response signal / code back to the control unit 10.
  • the control unit 10 recognizes which transponders Tl, T2, Tn are within the range of the transmitter / receiver 14.
  • the evaluation of which transponder Tl, T2, Tn is present can be carried out, for example, on the basis of a characteristic transmission time delay of the response signal which differentiates the transponders Tl, T2, Tn.
  • a corresponding time slot is assigned to each transponder Tl, T2, Tn. Comes in within this characteristic time slot
  • the control unit 10 recognizes that the transponder Tl, T2, Tn responding within this time slot is within range.
  • the binary information is generated as to whether the respective transponder T1, T2, Tn is present (x) or not (0).
  • the authorization query in step 103 can also be triggered in connection with the opening or closing of the doors or when an operating element is actuated in conjunction with a start or stop operation of the motor vehicle.
  • those transmitters / receivers 14 which control the interior of the motor vehicle are activated in the sense of sending out a search signal.
  • the incoming response signals from the transponders Tl, T2, Tn indicate which transponders Tl, T2, Tn are in the interior of the vehicle. This information is available in step 111 of the display 26.
  • the authorization query 103 follows. For this purpose, a signal is sent to the first transponder T1 recognized as being present, which the first transponder T1 processes. The first transponder T1 sends the processed signal back as a code.
  • the identical procedure for determining the expected code runs in parallel in the control unit 10.
  • step 105 If the incoming code of the first transponder T1 coincides with the expected code, the authorization procedure has been successfully carried out, step 105. If there is a discrepancy, it is terminated without result, step 107.
  • step 103 either an access authorization follows Motor vehicle or a driving authorization that causes the control units necessary for operation to be activated and thus opens up the possibility for the user to start the engine.
  • the control unit 10 sends a command signal via the bus system 18 and the data to be displayed, such as transponder Tl, T2, Tn, name Nl, N2, Nn, the transponder-dependent binary information and the settings El, E2, En to the Display unit 24. These data are only intended as examples for any information to be displayed.
  • the control unit 10 for each transponder T1, T2, Tn the name Nl, N2, Nn of the corresponding transponder user. This is shown alphanumerically on the display of the display 26.
