Abstract

The present application concerns a vehicle security device with particular use of a vehicle identity (VID) card 1 to eliminate theft. In one aspect, the invention is a vehicle key 8 suppressor for inhibiting communication between an electronic start key 8 (including, for example a conventional coded ignition key 8 as well as an advanced key system, a remote keyless system, and a fingerprint and/or eye recognition system) and an engine control unit (ECU) 7 in a vehicle. When activated by an activating signal from the VID card 1, the suppressor sends an inhibitory signal 5 which inhibits communication 6 between the start key 8 and the ECU 7, thereby preventing the vehicle engine from being started or restarted. The system may be provided with a tracking unit (10, figure 2) for remote tracking from a tracking station (13, figure 2). Alternatively, the System may require the VID card 1 to be within a specific radius 9 of the vehicle in order for the key 8 and the ECU 7 to communicate and the engine to start.

Description

I
Vehicle security device The present invention relates to a vehicle security device referred to as a vehicle identity card fitted with a Radio Frequency Identity (RFID) code, transmitter and receiver. Particularly for immobilising a parked vehicle, whether the engine is running or not and I or the recovery of a stolen vehicle if fitted with a tracker unit.
The tracker system works in conjunction with a Vehicle Identity Card which contains a Radio Frequency Identity Code, a transmitter and a receiver (hereafter referred to as VID card). There is placed an invisible line around the vehicle at a pre-set radius. This can be done by the Global Positioning System (GPS) working in conjunction with the tracker unit if fitted. If a tracker system is not fitted the VID card still activates the suppressor if it is not within a pre-set distance from the vehicle. If the vehicle identity card is not present in the vehicle or is outside the pre-set distance from the vehicle the suppressor is automatically activated. When the VID card is present in the vehicle or within the pre-set distance the suppressor is de-activated. If the vehicle is fitted with a tracker device the pre-set radius is set by the GPS system. If no tracker device is fitted the pre-set radius is set by a transmitter in the suppressor unit.
Vehicle immobilisers and/or alarm systems which aim to prevent a vehicle from being stolen are incorporated in most vehicles. lmmobilisers typically use a code in the vehicle electronic start or ignition key which is recognised by a radio frequency identity ("RFID") loop around the lock barrel and then checked against the vehicle's engine control unit ("ECU"). If a current and valid code match is not found, the ECU prevents the vehicle engine from being started. Early immobilisers used static codes, but more recent immobilisers are rolling codes or cryptography to prevent code-copying from the key or ECU.
Advanced key systems and remote keyless systems allow a driver to open and/or start a vehicle without inserting a key into a lock barrel. The advanced key emits an encoded radio signal or an encoded infrared signal which is detected by a sensor on the vehicle before the vehicle is allowed to start.
Other "key" systems include those which rely on fingerprint and/or eye (iris pattern) recognition and also a Vehicle Identity Card.
Despite the advances in immobilising systems, vehicle theft is still a problem.
One way that thieves bypass immobiliser security is to target vehicles which have already been started correctly and are running with a key in place, for example when a vehicle is stationary at traffic lights. Therefore, many vehicles are now fitted with a vehicle tracking system which allows a vehicle owner or a third party to track the location of the vehicle, and also optionally the speed and/or other vehicle information. Tracking systems may employ Global Positioning System (GPS) technoJogy, Automatic Vehicle Location (AVL) technology, and/or a cellular transmitter to allow a third party to remotely identify the position of the vehicle.
The present invention provides an alternative device and method for immobilising a parked vehicle. Also vehicle recovery when a tracker unit is fitted. If a parked vehicle is fitted with a tracking device the invisible pre-set circle is continuously active and remains so until the VID card is present or within the pre-set circle. Once the VID card is present in the vehicle or within the pre-set radius the suppressor is de-activated.
According to the first aspect of the invention, there is provided a vehicle suppressor containing a receiver for inhibiting communication between an electronic start key and an engine control unit ("ECU") in a vehicle. The suppressor when activated by an activating signal transmitted from the VID card (which contains a Radio Frequency Identity Code) which sends an inhibitory signal to the suppressor which in turn inhibits communication between the start key and the ECU, thereby preventing the vehicle engine from being started.
The invention there provides a way of inhibiting recognition by the ECU of the start key code. The suppressor comprises electronic circuitry so that when the suppressor is activated it sends an inhibitory signal. The inhibitory signal may suppress, interrupt, scramble and/or corrupt normal communication between the start key and the ECU. The inhibitor signal will thus prevent the vehicle engine from being started. The suppressor is used in combination with VID card, which activates the suppressor. If vehicles are fitted with tracker systems this means that it will be easier to locate the vehicle.
Several different frequencies are used for communication between the start key and the ECU. The suppressor may be programmed to inhibit any or all of these frequencies, for example by suppress, interrupt, scramble and/or corrupt the communication.
As used herein, the terms "electronic start key" and "start key" encompass conventional coded ignition keys as well as advanced key systems, remote keyless systems and fingerprint and/or eye recognition systems and also a Vehicle Identity Card. The terms "engine control unit" ("ECU") is deemed to be synonymous with "engine management unit" ("EMU"), also known as a vehicle computer. The term "vehicle" encompasses cars and other terrestrial vehicles, as well as vehicles which travel in or on water, such as ships, and vehicles which travel in air, such as aeroplanes.
The suppressor may comprise a receptor means for receiving the activating signal from the VID card. The suppressor may comprise a signal means operably linked to the receptor means for sending the inhibitory signal.
The VID card may comprise a control means for receiving a control signal emitted by a transmitter in the vehicle. The suppressor is therefore controlled by the VID card or if fitted, may be used in conjunction with a tracker system and Global Positioning System.
The tracking system may comprise an activating means operably linked to the control means for sending the activating signal to the suppressor in response to the control signal.
The suppressor may be deactivated when a deactivating signal is received from the VID card. Here, a single activating signal may be required to activate the suppressor which will remain active until the deactivating signal is received.
Alternatively, the suppressor may be deactivated when the activating signal from the VID card is stopped. Here, the activating signal may be a continuous signal from the VID card which, when stopped, de-activates the suppressor. Also this activation and de-activation can be achieved in conjunction with a tracker unit and Global Position System if fitted.
The inhibitory signal from the suppressor in one embodiment does not stop the vehicle engine if it is running. For reasons of safety, for example, it may not be advisable to immobilise a vehicle if it is in motion. In this embodiment of the invention, the activated suppressor prevents the engine from being re-started after it is has been switched off.
The suppressor is in one aspect powered by an independent power supply.
The suppressor may provide a status signal to the VID card, which in turn may communicate the status of the suppressor to the VID card.
The inhibitory signal emitted by the suppressor may be of ten milliwatts or less, to comply with MPT and ETS regulations. It may be adjusted lower than ten milliwatts on test to ensure that it does not affect other vehicles.
The inhibitory signal may comply with appropriate standard performance specifications, for example with United Kingdom or other national MPT regulations and/or European Telecommunications Standards ETS regulations.
The suppressor may be linked to the VID card The suppressor may be easy to install either during manufacture of the vehicle or afterwards, for example in combination with installation of a tracking system or independently of a tracking system.
The suppressor may be activatable in response to the activating signal from the VID card or in conjunction with a tracker and GPS system. In other words, the invention may be independent of systems which require the use of telephone signals such as mobile phone signals.
Also provided according to the present invention is a vehicle security system comprising a suppressor as defined herein.
Further provided is a vehicle comprising a suppressor as defined herein or a security system as defined herein.
In another aspect of the invention where a tracker and GPS system is fitted there is provided a method for recovering a vehicle comprising a suppressor as defined herein or a security system as defined herein, in which the method comprises the steps of activating the suppressor so that the vehicle engine is prevented from being restarted, locating the vehicle via the tracking system, and then recovering the vehicle.
When a VID card is used either in conjunction with a tracker system and GPS on a vehicle or used as an independent unit on a vehicle, either of which will be linked to the suppressor according to the present invention.
Particular non-limiting examples of the present invention will now be described with reference to Figs. I and 2 which are schematic views of a vehicle key suppressor controlled by a Vehicle Identification Card. Fig I is for a vehicle that does not incorporate a tracking device. Fig. 2 shows the system when a tracking device is fitted Fig. I When the vehicle identification card (1) moves outside the pre-set radius (9) it transmits a signal (2) to the suppressor (3). This signal is received via the antenna (4). The suppressor (3) then transmits a signal (5) with interrupts, corrupts or scrambles the signal (6) between the ECU (7) and the micro chipped key (8). The vehicle is then immobilised or prevented from being re-started if the engine is running.
Fig. 2 When the vehicle identification card (1) moves outside the pre-set radius (9) it simultaneously transmits a signal (2) to both the suppressor (3) and the tracker unit (10). The signal to the suppressor is received via the antenna (4).
This automatically activates the suppressor (3) therefore inhibiting, scrambling or interrupting the signal (6) from the ECU (7) to the key (8). The tracker unit (10) transmits a signal (12) to the tracker station (13). This alerts the tracker station (13) that the vehicle has been moved outside the pre-set radius (9) without the presence of the identification card (1). The tracker station (13) may then contact the owner of the vehicle to advise them that the vehicle has been moved outside the pre-set radius (9) without the presence of the identification card (1) and therefore ask if the car has been taken by an unauthorised person. If this is the case the tracker station (13) can track (11) the position of the vehicle. The suppressor (3) has already been activated and therefore when the vehicle stops it cannot be re-started. The tracker station (13) will then be able to identify the position of the immobilised vehicle.
A power supply (15) for the suppressor can be supplied from the tracker unit.
When a vehicle is stolen the tracking company is alerted by the absence of the VID card. If stolen the tracker and suppressor are both fully activated.
In one embodiment, the inhibitory signal transmitted by the suppressor does not stop the vehicle while it is running. However, the inhibitory signal would prevent the engine from being re-started as the standard signal from the ignition key would not be recognised by the ECU because it has been interrupted and/or scrambled by the activated suppressor.
The status of the suppressor is transmitted back to the VID card and can be transmitted back to the tracker control centre, if a tracker is fitted through a status connection link (14) between the suppressor and the tracker.
Once the suppressor has been activated the vehicle is not stopped while it is in motion because of the obvious dangers that could arise, in the present embodiment when the vehicle has been stopped by the thief it is then prevented by the suppressor from being re-started -if a tracker system is fitted, the tracker company can direct the owner and/or the police to recover the vehicle. Once the vehicle is recovered, the suppressor can be de-activated by the presence of the VID card and normal vehicle operation resumed.
Although the present invention has been described with reference to preferred or exemplary embodiments, those skilled in the art will recognise that various modifications and variations to the same can be accomplished without departing from the spirit and scope of the present invention and that such modifications are clearly contemplated herein. No limitation with respect to the specific embodiments disclosed herein and set forth in the appended claims is intended nor should any be inferred.
