Abstract
A trip computer 10 of a vehicle is provided with a first six digit display 14 and a second three digit display 16, a microprocessor 18 and a memory 20. An input panel 22 includes a trip reset button 24. The memory 20 stores the vehicle identification number (VIN). The microprocessor 18 is arranged such that, if the trip reset button 24 is pressed and held down for a predetermined time (or pressed a predetermined number of times in a predetermined period) the VIN is displayed on the six digit display 14. This identifies the trip computer 10 with the vehicle in which it is installed, and prevents its replacement by a trip computer from another vehicle. A vehicle radio may be used in place of the trip computer. <IMAGE>
Description
Vehicle Security Coding The present invention relates to vehicle security, and in particular to a method of coding certain electronic components of a vehicle so that the identity of the vehicle cannot easily be disguised.
It is known from GB2227791 to provide a vehicle having a trip computer in which the vehicle identity number (VIN) is stored. The trip computer can be interrogated via a diagnostics link during servicing to check that the VIN stored in it corresponds to that of the vehicle.
The present invention aims to provide a vehicle security system in which electronic components of the vehicle can be coded and in which the coding can be checked easily.
Accordingly the present invention provides a vehicle including an electronic component having a memory arranged to store an identification code to identify the electronic component with the vehicle, the vehicle further comprising display means and input means arranged such that when the input means is operated in a predetermined manner, the stored identification code is displayed on the display means.
The identification code is preferably also applied to at least one other part of the vehicle. For example it may be stamped or engraved onto the vehicle bodywork or engine or etched onto the windows or applied to any part of the vehicle using paints of various sorts.
Preferably the display means is formed as part of the electronic component.
Preferably the input means is formed as part of the electronic component.
The input means may comprise a push button.
The electronic component may be a trip computer, or a more conventional odometer, and the input means may, for example, be a reset button of the component.
The predetermined input may comprise pressing the push button a predetermined number of times in a predetermined period, or holding the push button down for a predetermined period.
The identification code is preferably entered into the memory of the component during manufacture of the vehicle, for example via a diagnostics link provided for the trip computer.
A preferred embodiment of the present invention will now be described by way of example only with reference to the accompanying drawing which is a diagrammatic representation of a trip computer installed in a vehicle according to the invention.
A trip computer 10 comprises a digital display panel 12 having a first six figure display 14 and a second three figure display 16, a microprocessor 18, and a memory 20.
The six digit display 14 normally displays the total mileage of the vehicle, and the three digit display 14 shows the trip mileage. Input means in the form of an input panel 22 is provided having a number of inputs including a trip reset button 24. When the trip reset button 24 is pressed the mileage displayed on the three digit display 16 is reset to zero. The other inputs on the input panel 22 can be used to make the trip computer perform various other operations. However these will not be described in detail since they are not relevant to the invention.
The memory 20 has the vehicle identification number (VIN) of the vehicle stored in it, in such a way that it cannot easily be overwritten. The microprocessor 18 is arranged such that, if the reset button 24 is held in a depressed position for more than a predetermined period, for example five seconds, the VIN is displayed on the six digit display 14. The VIN is displayed for a fixed period, for example 15 seconds and then the display returns to its original state showing the vehicle mileage.
It will be appreciated that the arrangement described makes it very difficult for a trip computer from one vehicle to be replaced by another trip computer taken from another vehicle. This is because anybody, including the driver, can check the VIN stored in the trip computer to make sure that it corresponds with that of the vehicle in which it is installed. There is no need for the vehicle to be taken to a specialist service garage with diagnostic equipment for checking the stored VIN.
It will also be apparent that the identification method described above can be used in other electrical components on the vehicle. For example a vehicle radio which has a digital tuning system could easily be provided with a memory in which the VIN could be stored. Any of the inputs already provided, such as the tuning or frequency selection buttons could be used as the input for calling up the VIN on the digital display.
Claims (9)
1. A vehicle including an electronic component having a
memory arranged to store an identification code to
identify the electronic component with the vehicle, the
vehicle further comprising display means and input means
arranged such that when the input means is operated in a
predetermined manner, the stored identification code is
displayed on the display means.
2. A vehicle according to claim 1 wherein the display means
is formed as part of the electronic component.
3. A vehicle according to claim 1 or claim 2 wherein the
input means is formed as part of the electronic
component.
4. A vehicle according to any foregoing claim wherein the
input means comprises a push button.
5. A vehicle according to claim 4 wherein the predetermined
input comprises pressing the push button a predetermined
number of times in a predetermined period.
6. A vehicle according to claim 4 wherein the predetermined
input comprises holding the push button down for a
predetermined period.
7. A vehicle according to any foregoing claim wherein the
electronic component is a trip computer.
8. A vehicle according to any one of claims 1 to 6 wherein
the electronic component is an odometer.
9. A vehicle according to claim 7 or claim 8 wherein the
input means is a reset button.
1O.A vehicle substantially as hereinbefore described with
reference to the accompanying drawings.
