Definitions

  • the present invention relates to a method and a device for tamper-proofing of an odometer or a vehicle recorder of a motor vehicle.
  • From the DE OS 29 11 1160 is a device for preventing unauthorized operation of vehicles with a preferably associated with the provided for the mechanical locks of the vehicle key Information carrier and with an evaluation circuit which triggers a signal when the correct information was entered, known. It is described there in particular that the state of an odometer and / or an operating hours counter can be transferred to the vehicle key and stored there. The vehicle can only be restarted if, during the starting process, the start of the odometer or the operating hours counter is transmitted from the key back to a vehicle-side evaluation unit. This document is concerned with an anti-theft device of vehicles, but not with the recent occurrence of more frequent manipulation of odometers or tachographs.
  • Another prior art document is GB 2326720 A , It describes a method for tamper-proofing of odometer, in which the odometer reading is read at regular intervals and stored in several non-volatile, in-vehicle memories. These stored values are periodically synchronized, with the largest stored value overwriting smaller values. In this synchronization, the value currently displayed by the odometer is included.
  • the object of the invention is a simple and inexpensive provision of a tamper-proofing of odometer or tachographs of motor vehicles.
  • an alarm signal is output in case of disagreement of the respective distances.
  • Such an alarm signal can be transmitted either directly acoustically or visually, or via appropriate radio communication means to a backup center.
  • a backup center In conjunction with corresponding, known per se locating a motor vehicle, which is subjected to a manipulation of the odometer, can be found in a simple manner.
  • the means for determining the current odometer reading and / or comparing the odometer reading at engine restart with a stored odometer reading in the form of a combination instrument and according to the invention the means for initiating appropriate measures for the In the event that the odometer reading found during the engine restart and the stored odometer reading do not match, realized in the form of a transmission or engine control unit.
  • a transmission or engine control unit Such, conventionally provided in motor vehicles facilities can be modified without or with little effort in terms of the specified functionality.
  • a step 100 takes place when stopping the engine of the motor vehicle, a storage of Wegumblen- or Km-level of the odometer.
  • the storage of the mileage takes place in a memory of an in-vehicle control unit, which has influence on the vehicle movement.
  • a per se known engine control unit is given.
  • a control unit initialization takes place, again in a manner known per se (step 101).
  • the mileage stored in the memory of the control unit is read out.
  • the current odometer reading of the odometer read.
  • the read out of the memory of the controller odometer reading is compared in a step 104 with the current odometer of the odometer. The comparison can be carried out for example by the control unit in which the storage of the mileage was carried out, or any other control unit.
  • step 104 If it is determined in step 104 that the current mileage corresponds to the stored mileage, in particular, that the current mileage is greater than or equal to the stored mileage, it can be assumed that no manipulation of the odometer was performed, since such manipulations are typically for the purpose of pretending lower mileage can be used.
  • step 105 a storage of the current mileage takes place in this case. Subsequently, the process branches from step 105 to a step 107, in which it is effected that the normal controller program can be performed.
  • step 105 d. H. a storage of the current mileage when the engine is restarted, can be dispensed with and a storage of the corresponding mileage can be provided only at a further shutdown of the engine, as has already been explained with reference to step 100.
  • step 104 determines that the current mileage does not correspond to the stored mileage, in particular is less than this in a step 106. That is, since in this case an odometer manipulation must be assumed, various suitable measures can be initiated in addition to the inhibition of the motor function of the motor vehicle, for example the triggering of an alarm signal. After carrying out such measures, a branch to the step 107, which makes it possible to carry out a normal control program, can also be carried out here.
  • the method according to the invention provides a simple manipulation protection of an odometer which can be provided essentially without additional costs. To effectively carry out a manipulation would have to be made simultaneously in the cockpit or the odometer and in the control unit changes; this represents a significantly higher and technically difficult effort compared to conventional options, and is effectively only by authorized repairers who are equipped with appropriate tools, feasible.
  • FIG. 2 A preferred embodiment of the device according to the invention is shown schematically in FIG. 2 shown. 1 and 2 hereby designate a first or a second control device.
  • the control units 1, 2 are connected to one another via a data exchange line, for example a bus line.
  • a data exchange line for example a bus line.
  • At least one of the control units 1, 2 is in this case able to read in a current mileage and compare it with a stored mileage.
  • at least one of the control units 1, 2 is able to initiate the desired reaction, for example an inhibition of the engine function of the motor vehicle or the triggering of an alarm or locating signal.
  • control unit 1 for example, by the instrument cluster, and the control unit 2, for example by the transmission or engine control unit.
  • the instrument cluster 1 would send the data to the transmission or engine control unit 2, which compares the data with each other and initiates a corresponding reaction.
  • the device described can also be implemented in the form of only one control unit or in the form of more than two control units.
