Abstract

A system for remotely disabling or enabling an automobile having at least one receiver that scans signal codes transmitted in frequencies dedicated to mobile telephone communications, and at least one frequency outside that used in mobile telephone communications. The signal codes received by the receiver are compared to an enabling code and a disabling code stored within a programmable memory. When the owner of an automobile finds the vehicle stolen, the owner dials the telephone number corresponding to the disabling code of the automobile. The dialed number causes a signal code to be transmitted from the mobile telephone transmitted network, wherein the signal code is received by the stolen automobile. If the transmitted signal code matches the programmed disabling code the automobile is disabled. Similarly, the automobile can be enabled if a signal code is received that matches the enabling code the automobile. The signal code corresponding to the disabling and enabling codes for the automobile can also be transmitted on a frequency not used in mobile telephone communications by portable transmitters carried by police. As such, a stolen automobile can be selectively disabled by police if located.

Claims

1. A security system for a vehicle, comprising:

arming means for selectively enabling and disabling said vehicle security system, wherein said arming means includes a receptacle disposed to receive a transportable receiver within said vehicle, said arming means enabling said security system when said transportable receiver is removed from said receptacle and disabling said security system when said transportable receiver is placed within said receptacle;

at least one theft sensor for producing an trigger signal when the vehicle is tampered with;

a transmitter means, coupled to said at least one theft sensor, for transmitting an alarm signal when said transmitter receives said trigger signal from said at least one theft sensor, whereby said alarm signal is received by said transportable receiver and said transportable receiver produces an audible alarm in response to said alarm signal;

at least one receiving means coupled to said at least one theft sensor, wherein said at least one receiving means is enabled upon receipt of said trigger signal, said receiving means capable of receiving control signals from a range of frequencies, use in mobile telephone communications, and at least one dedicated frequency outside of said range of frequencies;

memory means containing at least one enabling code and at least one disabling code;

comparison means for comparing control signals received by said at least one receiving means to said at least one enabling code and disabling code; and

vehicle control means for disabling said vehicle when said control signals match said at least one disabling code and enabling said vehicle when said control signals match said at least one enabling code.

2. The system according to claim 1, further including a variable input means, coupled to said memory means, through which said at least one disabling code and said at least one enabling code can be selectively entered into said memory means.

3. The system according to claim 1, wherein said variable input means is coupled to said comparison means, whereby a code input through one disabling code, and said vehicle control means disables said vehicle when said code matches said at least one disabling code and enables said vehicle when said code matches said at least one enabling code.

4. The system according to claim 3, wherein said at least one receiving means is part of a mobile telephone device preinstalled in said vehicle.

5. The system according to claim 4, wherein said variable input means includes a dialing keypad contained within said mobile telephone device.

6. The system of claim 1, wherein said vehicle includes an ignition system and said vehicle control means controls the operation of the ignition system.

7. The system of claim 6, wherein said vehicle includes a starter and said vehicle control means controls the operation of the starter for said vehicle.

8. The system of claim 1, wherein said vehicle includes emergency lights and said vehicle control means controls the operation of the emergency lights for said vehicle.

9. The system of claim 1, further including a signaling means for producing a visible signal on said vehicle when said at least one receiving means is enabled by said trigger signal.

10. The system of claim 9, wherein said vehicle includes license plate lights and said signalling means controls the license plate lights.
