Definitions

  • the invention relates to a data communication device for a vehicle pulled by a motor vehicle, the electric Operating energy via a cable connection to the motor vehicle is transmitted.
  • the invention further relates to a use of such a data communication device.
  • ABS anti-lock braking system
  • ABS of the trailer For the activation of the ABS of the trailer must be a plug of the trailer in a standardized socket of the vehicle can be plugged in so the control unit receives its power supply. About the connection is also an error signal that indicates whether the ABS is working properly or one contained in the ABS Self-test device has detected a malfunction.
  • Newly developed anti-lock braking systems have an expanded Control on, in the further data such as air suspension, type of error and an electronic odometer can be integrated can.
  • pad wear monitoring can be carried out performed for the brakes and the corresponding data saved become. These data are output regularly via a diagnostic socket by hand and requires one manual documentation or via a connectable portable Terminal to which the data can be transferred.
  • the present invention is therefore based on the problem from capturing trailer data largely tamper-proof and easy to handle.
  • a data communication device of the type mentioned in the introduction through its own power supply, a data acquisition unit and a short-range wireless transmission and Receiving device for transmitting data from the data acquisition unit to an external sending and receiving station.
  • the data communication device data acquisition for the trailer self-sufficient from the towing vehicle, so that a cut in the power supply by interrupting the power supply from the towing vehicle is not possible.
  • the Transfer of the data stored in the data acquisition unit takes place with the data communication device according to the invention wirelessly via a short-range transmitting and receiving device to an external sending and receiving station.
  • data communication can be done regularly when driving past be carried out at an external sending and receiving station, expediently the transmitting and receiving device of the towed vehicle formed by a transponder is, so that the data communication through the external transmission and Receiving station is triggered.
  • a pulse generator on at least one wheel of the towed vehicle provided depending on the movement of the Rades emits pulses, at least on a power supply unit come with a rectifier, so that from the preferably also used as measuring pulses Energy for the data acquisition unit is generated.
  • a backup battery Power supply can be provided, for example, during an extreme slow travel that is transmitted by the impulses electrical energy should become too low.
  • brake light and direction indicator be provided, from which energy may be drawn can, which is preferably stored in a rechargeable battery becomes.
  • the short-range wireless data communication preferably takes place in the GHz range.
  • a data communication system that works with a transponder in the vehicle, is from proposals for traffic control technology, in particular the automatic collection of road tolls, known and for example in principle in DE 42 13 880 A1 explained.
  • Data acquisition unit can be in a preferred embodiment Part of one installed in the towed vehicle Control for a brake lock protection device.
  • the pulse generator is preferably also a sensor the anti-lock device. Because from the wheel impulses of the sensors the anti-lock device all movements of the wheels can be determined and evaluated, this can be done without further used to determine the distance traveled become.
  • the data acquisition unit according to the invention can of course be used also record additional data or with other data sources to be connected. This includes all data sources from the known ABS devices. Additional data is identification data for the trailer and possibly other data that especially for controlling an immobilizer function for the trailer can be used for authorized use only of the trailer.
  • the immobilizer function can, for example, through a joint effectiveness control all the brakes on the trailer are applied, i.e. to the ABS belonging pneumatic valves.
  • the data communication device can in particular use with advantage at rental stations for trailers, where an automatic issue and return control for the towed vehicle with the external transmission and Receiving station can be made. Furthermore, it is possible the data of the trailer also to control entry and / or to use exit controls.
  • the sending and receiving station has one Antenna 3 on, for a short-range transmission of Data in interaction with an antenna 4 of a trailer 5, which is a towed vehicle.
  • the antenna 4 of the trailer 5 is part of a transmitting and receiving device 6, which are preferably designed as transponders and for communication with the transmitting and receiving station on one frequency of 5.8 GHz is determined.
  • Communication between the Transmitting and receiving station 1 and the transmitting and receiving device 6 takes place sequentially by sending out a pulse train the transmitting and receiving station 1 (uplink) and by modulation the pulse train for the transmission of data information through the transponder 6 and return the modulated Pulse signals (downlink).
  • the advantage of this communication method that is described, for example, in DE 42 13 880 A1 is that the one required by the transponder Energy 6 from that of the transmitting and receiving station 1 transmitted pulse signals is obtained.
  • the data transmitted by the transmitting and receiving device 6 are generated and processed in a data acquisition unit 7.
  • four wheels 8 of the trailer 5 each have a sensor 9 connected, the output pulses depending on the movement of the assigned Rades 8 generated, that is, represents a pulse generator that Generated pulses depending on the movement of the wheels 8.
  • the pulses from the sensors 9 reach a controller 10, in which evaluates the movements of the wheels 8 and ABS control signals generated with which the effect of the brakes is controlled becomes.
  • the pulses from the sensors 9 also reach one Distance counter 11, in which from the pulses of the sensors 9 the distance traveled by the trailer 5 is evaluated.
  • the route signal formed is sent via a communication interface and data memory 12 as a processed data signal to the transponder 6.
  • the power supply unit 14 equipped with a backup battery 15 be those that are particularly slow for the extreme exceptional cases Drive takes over the power supply.
  • the backup battery 15 can be designed as an accumulator, again and again can be charged.
  • Figure 2 shows an embodiment of a power supply ABS control 10 through branch lines 16 from power supply lines 17 for indicators and warning lights 18 of the trailer 5.
  • the power supply lines 17 are via a Connector 19 of the trailer 5 supplied by the towing vehicle, which is also done by charging a backup battery can.
  • the ABS control unit 10 is connected to the via a plug 20 Connected towing vehicle.
  • the data acquisition unit 7 according to the invention and the transmit and Receiving device 6 can be independent of a power supply of the towing vehicle are and always are ready for operation, so that odometer counting takes place continuously.
  • the data determined in the process are stored in the data memory 12 stored and are by a transmit and Receiving station 1 in cooperation with the transmitting and Receiving device 6 of the trailer 5 constantly available and verifiable.
