Description

    FIELD OF THE INVENTION
  • The present invention relates to the field of locating stolen vehicles, and recovering the same, and more particularly concerns an improvement in a system for locating such a vehicle or the like. [0001]
    • BACKGROUND OF THE INVENTION
  • With the ever increasing amount of vehicles equipped with wireless communication and positioning technologies, such as cellular phones and GPS antennas, there has been a growing interest in the field of anti-theft devices to use these technologies to locate stolen vehicles. [0002]
  • For example, U.S. Pat. No. 5,895,436 (SAVOIE et al) discloses a vehicle tracking system using an existing cellular network. In this system, the vehicle to be tracked is provided with a cellular transceiver hidden somewhere on the vehicle to prevent easy detection thereof, and operating on continuous standby mode. Upon activation of the system, the cellular transceiver is paged and one or more cells of the network located near the stolen vehicle are identified. A search vehicle is then informed of a search parameter defined by these cells. [0003]
  • U.S. Pat. No. 5,918,183 (JANKY et al.) concerns a concealed mobile communication system. Janky teaches mounting the antennas and transmitters/receivers of a GPS unit or cellular phone of both, so that a thief could not locate and therefore deactivate these systems, which may then be used to communicate information to the owner of the vehicle, a searching entity or the police. The various components of the locating equipment according to this patent however need to be connected together with wires, and these wires also need to be concealed if two components are apart from each other. [0004]
  • U.S. Pat. Nos. 5,418,537 (BIRD) and 5,918,180 (DIMINO) also disclose missing vehicle location systems or methods using cellular and GPS technologies. [0005]
    • SUMMARY OF THE INVENTION
  • It is an object of the present invention to provide a system for locating a stolen vehicle including positioning technology where hidden location equipment is not connected with wires and which may be followed to disclose its position. [0006]
  • Accordingly, in a system for locating a stolen vehicle including: [0007]
  • a wireless transceiver for transmitting vehicle positioning information to a searching entity, the wireless transceiver being installed at a hidden location on said vehicle; and [0008]
  • a positioning device for receiving the vehicle positioning information from satellite sources, the positioning device being installed on the vehicle at a location different from the hidden location of the wireless transceiver, [0009]
  • the present invention provides the improvement wherein the system further includes wireless communication means for transmitting the vehicle positioning information from the positioning device to the wireless transceiver. [0010]
  • In accordance with another aspect of the invention, there is provided a system for locating a stolen vehicle including: [0011]
  • a wireless transceiver for transmitting vehicle positioning information to a searching entity, the wireless transceiver being installed at a hidden location on said vehicle; and [0012]
  • a positioning device for receiving the vehicle positioning information from satellite sources, the positioning device including a GPS antenna installed on the vehicle at a location different from the hidden location of the wireless transceiver, and a GPS chipset installed at the hidden location, [0013]
  • the improvement wherein the system further includes wireless communication means for transmitting the vehicle positioning information from the GPS antenna to the GPS chipset. [0014]
  • Other features and advantages of the present invention will be better understood upon reading the following description of preferred embodiments thereof, with reference to the appended drawings. [0015]
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a diagram illustrating the context of the present invention. [0016]
  • FIG. 2 is a diagram showing a system according to a first embodiment of the invention. [0017]
  • FIG. 3 is a diagram showing a system according to a second embodiment of the invention. [0018]
    • DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
  • Referring to FIGS. 1 and 2, the present invention concerns a [0019] system 10 for locating a stolen vehicle 12. Vehicle 12 is preferably a car but the present invention may easily be applied to any movable object susceptible to be stolen, such as buses, construction equipment, etc.
  • The [0020] system 10 first includes a wireless transceiver 14, preferably embodied by a cellular transceiver in communication with a network of stations 16. The transceiver 14 is adapted for transmitting information to a searching entity, during circumstances where the vehicle is to be located. For example, the present invention may be used in conjunction with a remote locating method using a tracking vehicle such as described in U.S. Pat. No. 5,895,436, which is incorporated herein by reference. The transceiver 14 is installed at a hidden location on the vehicle 12, in such a manner as to prevent a thief from easily spotting and consequently deactivating it.
  • The [0021] system 10 further includes a positioning device 18, preferably embodied by GPS antenna 20 and chipset 22. GPS antennas are well known in the art and are readily available. The positioning device 18 receives through the antenna 20 vehicle positioning information from satellites 24. In the present embodiment, the positioning device 18 is installed on the vehicle 12 at a location different from the hidden location of the transceiver 14. Since GPS antennas presently need to be in a direct line of site with satellites 24, the positioning device 18 is therefore preferably installed at a location inside of the vehicle 12, but in view of the satellites 24.
  • For the system described above to work, there is a need for means to transmit the vehicle positioning information from the [0022] positioning device 18 to the transceiver 14. However, connecting the two with wires would compromise the secrecy of the transceiver's hidden location, since a thief could follow the wires from the positioning device all the way to the transceiver.
  • The present invention therefore provides the improvement wherein the [0023] system 10 further includes wireless communication means for transmitting the vehicle positioning information from the positioning device 18 to the wireless transceiver 14. These wireless communication means are preferably embodied by an omni-directional radio frequency antenna 26 connected to the GPS chipset 22, and a radio-receiver 28 connected to the transceiver 14. Also preferably, the radio frequency antenna 26 uses radio waves of a frequency of about 900 MHz.
  • Consequently, when the system is activated, indicating that the vehicle or object needs to be tracked, the signal is sent to the GPS antenna to activate itself and read or receive information from the appropriate satellites. This information is then relayed to the transceiver on board the vehicle or object, which transmits this information to the search entity. The entity may then transfer the information to a tracking vehicle, which uses it to track the vehicle or object. [0024]
  • Referring to FIG. 3, there is shown a second preferred embodiment of the present invention where the [0025] GPS chipset 22 is installed at the hidden location of transceiver 14. In this embodiment, the RF antenna is therefore directly connected to the GPS antenna 20, and the radio-receiver 28 is connected to the GPS chipset 22. Since they are at the same location, the GPS chipset 22 can be connected by wires 30 or directly on board to the transceiver 14 without any risks of disclosing the hidden location to a thief. It will be readily understood by one skilled in the art that both embodiments are equivalent and that only the format of the vehicle positioning information at the moment of transmission by the radio antenna will be affected.
  • Of course, numerous modifications could be made to the embodiments described above without departing from the scope of the invention as defined in the appended claims. [0026]
