Definitions

  • the invention relates to a data communication device for a vehicle pulled by a motor vehicle, to which electrical operating energy is transmitted to the motor vehicle via a cable connection.
  • the invention further relates to the use of such a data communication device.
  • ABS anti-lock braking system
  • An error signal can also be transmitted via the connection, which indicates whether the ABS is working correctly or a self-test device contained in the ABS has detected a functional fault.
  • Newly developed anti-lock braking systems have an expanded control system in which further data such as air suspension, type of fault and an electronic odometer can be integrated.
  • pad wear monitoring can be carried out for the brakes and the corresponding data can be saved. This data is regularly output via a diagnostic socket by hand and requires manual documentation or a portable terminal to which the data can be transferred.
  • the electronic distance counting by counting the wheel impulses of the ABS fails if the driver foregoes the ABS activation for manipulation reasons, i.e. pulls the ABS connector and thus interrupts the power supply to the ABS caused by the towing vehicle. In this case, the ABS is no longer effective, but the pneumatically normal-acting brakes still work.
  • the present invention therefore starts from the problem of being able to capture trailer data largely tamper-proof and to be able to transmit it in a manner that is easy to handle.
  • a data communication device of the type mentioned at the outset is characterized according to the invention by its own power supply, a data acquisition unit and a short-range wireless transmission and reception device for transmitting data from the data acquisition unit to an external transmission and reception station.
  • the data communication device provides data acquisition for the trailer autonomously from the towing vehicle, so that it is not possible to cut off the power supply by interrupting the power supply from the towing vehicle.
  • the data stored in the data acquisition unit is transferred wirelessly with the data communication device according to the invention via a short-range transmission and reception device to an external transmission and reception station.
  • the data communication can be carried out regularly when driving past an external transmitting and receiving station, the transmitting and receiving device of the towed vehicle expediently being formed by a transponder so that the data communication is triggered by the external transmitting and receiving station.
  • An essential prerequisite for the data communication device according to the invention is that it operates with an extremely low power consumption, so that its own power supply can operate reliably and, for example, not on empty batteries or the like. is instructed.
  • a pulse generator is provided on at least one wheel of the towed vehicle which, depending on the movement of the wheel, emits pulses which at least also reach a power supply unit with a rectifier, so that preferably also used as measuring pulses Pulses the energy for the data acquisition unit is generated.
  • a backup battery can be provided for the supplementary power supply if, for example, the electrical energy transmitted by the pulses should become too low during an extremely slow travel.
  • a connection to the power supply for the rear light, brake light and direction indicator can also be provided, from which energy can be drawn, which is preferably stored in a rechargeable battery.
  • the short-range wireless data communication preferably takes place in the GHz range.
  • Such a data communication system which works with a transponder in the vehicle, is known from proposals for traffic control technology, in particular the automatic collection of road user charges, and is explained in principle in DE 42 13 880 A1, for example.
  • the data acquisition unit provided in the data communication device according to the invention can be part of a control system installed in the towed vehicle for a brake blocking protection device.
  • the pulse generator is preferably also a sensor of the anti-lock device. Since all the movements of the wheels can be determined and evaluated from the wheel impulses of the sensors of the anti-lock device, these can be used without difficulty to determine the distance traveled.
  • the data acquisition unit according to the invention can of course also record further data or be networked with other data sources.
  • Additional data are identification data for the trailer and possibly other data that can also be used in particular to control an immobilizer function for the trailer, in order to allow only authorized use of the trailer.
  • the immobilizer function can be carried out, for example, by a common effectiveness control of all brakes of the trailer, that is to say via the pneumatic valves belonging to the ABS.
  • the data communication device can be used particularly advantageously in rental stations for trailers, in which an automatic issue and return control for the towed vehicle can be carried out with the external sending and receiving station. It is also possible to use the trailer data to control entry and / or exit controls.
  • FIG. 1 shows a transmitting and receiving station 1, which can be installed stationary and connected to an evaluation center 2.
  • the transmitting and receiving station has an antenna 3, which is designed for short-range transmission of data in conjunction 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 is preferably designed as a transponder and is intended for communication with the transmitting and receiving station at a frequency of 5.8 GHz.
  • the communication between the transmitting and receiving station 1 and the transmitting and receiving device 6 takes place sequentially by sending out a pulse train from the transmitting and receiving station 1 (uplink) and by modulating the pulse train to transmit data information through the transponder 6 and sending back the modulated pulse signals ( Downlink).
  • the advantage of this communication method which is described, for example, in DE 42 13 880 A1, is that the energy 6 required by the transponder is obtained from the pulse signals transmitted by the transmitting and receiving station 1.
  • the data transmitted by the transmitting and receiving device 6 are generated and processed in a data acquisition unit 7.
  • a sensor 9 is connected to four wheels 8 of the trailer 5, the output pulses generated depending on the movement of the associated wheel 8, that is, represents a pulse generator that generates pulses depending on the movement of the wheels 8.
  • the pulses from the sensors 9 arrive at a controller 10, in which the movements of the wheels 8 are evaluated and ABS control signals are generated, with which the action of the brakes is controlled.
  • the pulses from the sensors 9 also reach a distance counter 11, in which the distance traveled by the trailer 5 is evaluated from the pulses of the sensors 9.
  • the route signal formed reaches the transponder 6 as a processed data signal via a communication interface and data memory 12.
  • data acquisition stage 13 data for identifying the special trailer 5 can also be entered, so that the transmitting and receiving station 1 can be used for automatic check-in and check-out in a rental station for trailers 5.
  • the entry or exit to or from the rental station can be controlled in a corresponding manner, for example by a barrier.
  • the output pulses from the sensors 9 are also passed to a power supply unit 14 in which the pulses are rectified and a DC voltage for supplying the data acquisition unit 7 is formed from this. It is assumed that a power supply for the odometer 11 is only required if the wheels 8 actually move.
  • the DC voltage produced by the power supply unit 14 may be too low to supply the data acquisition unit 7.
  • the power supply unit 14 can be equipped with a backup battery 15, which takes over the power supply for the extreme exceptional cases of a particularly slow journey.
  • the backup battery 15 can be designed as an accumulator that can be recharged again and again.
  • Figure 2 shows an exemplary embodiment of a power supply to the ABS control 10 through branch lines 16 from power supply lines 17 for flashing and warning lights 18 of the trailer 5.
  • the power supply lines 17 are supplied via a connector 19 of the trailer 5 from the towing vehicle, which is also done by charging a backup battery can be done.
  • the ABS control unit 10 is also connected to the towing vehicle via a plug 20.
  • the data acquisition unit 7 according to the invention and the transmitting and receiving device 6 can be operated independently of a power supply for the towing vehicle and are always ready for operation, so that an odometer is constantly being counted.
  • the data determined in this way are stored in the data memory 12 and can be called up and checked continuously by a transmitting and receiving station 1 in cooperation with the transmitting and receiving device 6 of the trailer 5.
