  • the remote operation means sends out a signal unique to the car.
  • the signal is preferably in a one-to-one relationship with the chassis number of the vehicle.
  • the control means is preferably controlled by electromagnetic control signals from the remote operation means.
  • the emitter preferably emits a visual and/or an audio signal.
  • the signal from the emitter can be detected by people passing by the car.
  • the system may include optical means, such as light-emitting means, preferably provided in the vicinity of a number plate of the vehicle, the optical means indicating that the vehicle has been stolen upon actuation of the control means.
  • the optical means may flash on and off. Again, an occupant of the vehicle cannot see that the optical means is indicating that the vehicle is stolen, but the general public can.
  • the optical means may be a light disposed adjacent a number plate of the vehicle. Both number plates may have optical means.
  • the optical means may comprise a part of the number plate, or may be provided on the vehicle separate from the number plate, for example in the vehicle's body panels.
  • the optical means alerts the public to the fact that the vehicle is wanted and tends to draw their eye to the number plate of the vehicle.
  • the system may also include audible means which may be set off remotely by the remote operation means and which emit a relatively quiet audible signal which can be detected by a pedestrian standing next to the vehicle, but which is too quiet to be heard by the driver of the vehicle whilst the vehicle's engine is running.
  • the audible means preferably produces a sound of 70dB or less, and most preferably 60dB or less. It may even be at 50dB or less.
  • the system may preferably be deactivated remotely, for example by the remote operation means.
  • the audible means can alert people who come close to a parked vehicle that it is stolen, but will not annoy people further away, for example in their homes.
  • a vehicle fitted with a system in accordance with the first aspect of the invention comprises a second aspect of the invention, and an add-on unit for attachment to a vehicle, the unit incorporating an emitter which can be remotely operated to emit a signal which is not readily noticed by an occupant of the vehicle comprises a third aspect of the invention.
  • a method of identifying a stolen vehicle comprises the steps of providing the vehicle with an emitter which can be remotely actuated to emit a signal; deliberately actuating the emitter when the vehicle is thought to be stolen, using manually controlled remote operation 5 means; and having observers in the vicinity of the vehicle detect the signal emitted by the emitter; the emitted signal being such as not to be readily detectable by the driver of the stolen vehicle.
  • the method includes the further step of the vehicle being adapted to emit a visible signal, preferably in the vicinity of at least one of its number plates, when the remote actuation means is manually activated.
  • the method may alternatively or additionally comprise the vehicle being adapted to emit a relatively quiet audio signal which can be heard by pedestrians near the vehicle, but which cannot be heard by the 0 driver of the vehicle over the noise of the vehicle's engine.
  • Figure 1 shows a vehicle fitted with a system in accordance with the first aspect of the invention
  • Figure 2 shows a number plate region of another vehicle
  • Figure 3 shows a number plate region of a further vehicle.
  • a vehicle 1 is shown in Figure 1 having radio controlled emitter means comprising a light and sound emitter 3.
  • the emitter 3 can be located at any convenient position on the vehicle and is shown as being installed near the rear number plate of the vehicle.
  • the emitter 3 comprises a light unit and a sound unit and is provided adjacent the front number plate 4 of the vehicle.
  • a second, similar, emitter 3' is provided adjacent the rear number plate of the vehicle.
  • the emitters 3 and 3' can be actuated remotely by a radio signal to flash their light units on and off to draw attention to the number plates of the vehicle, and to emit a noise (via their sound units) , again to draw attention to the vehicle.
  • the noise is relatively quiet and is such that the driver of a moving vehicle cannot hear it, but a pedestrian passing alongside a parked vehicle can hear it.
  • the light and sound units of the vehicle are actuated by the same signal, but in a modified version they may be actuated by different remote signals.
  • a car owner finds that his car has been stolen he contacts a responsible body (such as the police) who have the control of a remote activation controller 5.
  • the police then, using a person's conscious decision, activate the remote controller 5 which causes an activating radio signal to be sent out by suitable radio sending means.
  • the activating signal is detected by receiver, detection, means provided on the vehicle and electronic control circuitry on the vehicle causes the emitters 3 and 3' to be turned on.
  • the light units adjacent the number plates flash on and off, and a noise is emitted by the sound units.
  • a member of the public, or a policeman can then see that the vehicle is wanted by the police and report its location to them.
  • the flashing lights are at the number plate regions of the vehicle an observer's eye is drawn to them and there is an increased chance of the observer recording the vehicle's registration number.
  • the driver of the vehicle cannot see that there is a flashing light near his number plates and cannot hear the relatively quiet noise of the sound units. There is therefore an increased chance of apprehending the thief whilst he is with the vehicle.
  • the sound unit is helpful in catching the attention of pedestrians when the vehicle is parked such that its number plates, and therefore the flashing lights near them, are not visible. For example if a stolen- car is parked right up against a tree, or wall, with another car parked right behind it so that neither of its number plates can be seen, a passing pedestrian can still hear the sound unit going off.
  • the controller 5 sends out a signal which is unique, the unique signal having a one-to-one correspondence with the vehicle's chassis number, or possibly registration number. It will be appreciated that the signal emitted by the controller 5 is akin to a chassis number in that it cannot activate the wrong vehicle's emitters 3.
  • a further use for the radio emitter 2 is that once activated it can be used to locate or track a vehicle.
  • FIG. 2 illustrates the provision of a light unit 20 provided in an integral formation of a rear panel of a vehicle.
  • a number plate 21 is received in a shallow recess 22 and the light unit has lights 23 provided at the recess 22.
  • a separate sound unit 24 is provided. It will of course be appreciated that the sound unit need not be next to the number plate of a vehicle.
  • Figure 3 shows a light unit 30 comprising a border 31 which is a reflective red border when the unit 30 is unactivated, but which flashes the message "Call Police" around the number plate when activated.
  • the light unit separate from the number plate, but I also envisage a variable display number plate, such as a LCD display, which normal-ly displays the vehicles registration number, but which when activated alternates between the vehicle' s registration number and an alarm signal, such as "Call Police".
  • a variable display number plate such as a LCD display
  • an alarm signal such as "Call police”.
  • I may prefer to provide a light unit and sound unit, as a single add-on housing or unit.
  • the vehicle theft indication system is set off by a conscious decision of the keeper of the remote controller 5 and this should avoid accidental operation of the system, which would cause the public to take more notice of the "alarm" when it is activated. Furthermore, even when activated the system does not unduly annoy people in the neighbourhood.
  • a modified vehicle theft indication system is similar to that described with reference to Figures 1 to 3, but has the additional features discussed below.
  • the modified system is connected to the vehicles convention loud siren alarm, or is provided with its own loud siren alarm.
  • the loud siren alarm is adapted to be activated remotely by the police using a coded signal (usually a radio signal) independently of the visual and quiet alarm signals.
  • the modified system is arranged to be light-sensitive (by the provision of suitable sensors and control circuitry) so that if a thief tries to mask the light unit 20' by covering it, for example with black tape, the system can recognise this.
  • the system recognises that its light unit has been covered up and sounds its loud siren alarm.
  • the system recognises that its light unit has been covered up and sounds its loud siren alarm.
  • the activating signal for the light unit is sent out by the police the light-sensitive system detects this and sounds the siren alarm as well as activating the light and quiet sound alarm.
  • the vehicle is left in a locked (dark) garage, or in a quiet country lane at night, when the activation signal goes out the siren alarm sounds.
  • a further feature is that the system has a time circuit such that if the light unit and/or the quiet sound unit have been activated for more than a predetermined time the siren alarm cuts in and is activated as well.
  • a typical time delay might be around four to ten hours.
  • a thief When the system incorporates its own siren alarm, in addition to any conventional siren alarm which may be provided on a vehicle, a thief has the problem that even if he disconnects or disarms the vehicle's normal defences, such as steering lock and normal siren alarm, the system has detectors to check the operational state of the light unit and/or quiet sound unit so that if they are tampered with when the activating signal is received from the police the system recognises that the light or quiet sound units have been damaged and sounds its siren alarm. Thus the thief has to find and disconnect the receiver of the radio activating signal. The siren alarm only sounds when the "stolen" activating signal is sent by the police.
  • the loud siren of the modified system may be provided in the same unit as the, or either of, the emitters 3, or in a different place or unit.
  • a single add-on device may incorporate a light unit, quiet sound unit, and siren.
  • system comprises audible voice-producing means which is operable in response to a remotely transmitted voice-activating signal to speak a message to people outside of the vehicle.
  • the message may be pre-recorded and may be held in a memory medium in the system, playing of the message been activated by the voice-activating signal. More than one voice message may be held in memory means, a selected one being played in response to an appropriate identifying and triggering signal key of the voice-activating signal.
  • the system may comprise speaker means which produces the message spoken to people outside of the vehicle in response to modulation of a carrier signal, for example in the manner of a hi-fi radio (the person sending the voice-activating signal could speak into a radio microphone, or play a suitable tape into it) .
  • a carrier signal for example in the manner of a hi-fi radio (the person sending the voice-activating signal could speak into a radio microphone, or play a suitable tape into it) .
  • the system may be arranged to produce the voice message at predetermined intervals, or at intervals controlled by the controller of the activating signal.
  • audible voice-producing means is a tape playing device having a pre-determined voice -message on a tape, playing of the tape being triggered by the receipt of an appropriate voice-activating radio signal.
  • a typical voice message may be "Please telephone the police. This vehicle is wanted by the police”.
  • the audible voice producing means may comprise the audible means set of remotely by the user which emits a relatively quiet audible signal detectable by a passer-by but not readily detectable by the occupant of the vehicle.
  • voice-producing means may be provided in addition to the audible means.
  • the speech voice emitted by the voice-producing means may be quiet or it may be loud, and may even become loud after it has been sounding for a predetermined time.
