Abstract

A method and apparatus are disclosed in which a pocket pager or other data transmission device of conventional design is used to disable the starting sequence of a motor vehicle. More precisely, the radio device is connected to pull open a latching relay in the ignition key circuit, and once the pager receives its code all further vehicle restarts are disabled. The vehicle thus remains operational until shut off, and the relay then remains latched open until reset by a concealed push-to-close momentary switch. Alternatively, a second code combination may be transmitted to reset vehicle operation. In application, the signal to the pager will first be preceded by a telephone call from the vehicle leasing, financing or rental agency to a telephone number designated by the vehicle user, and if the response to this phone call is unsatisfactory only then is the pager disabling sequence effected. In this manner the user is first warned, and then the vehicle is disabled only when first shut off.

Claims

1. In a motor vehicle characterized by a power plant, means for transferring motive power from said power plant to the undercarriage of said vehicle, a starter connected to said power plant for starting the operation thereof, a battery for storing an electrical charge, a solenoid selectively connecting said battery to said starter, and a manually operative ignition circuit for selectively operating said solenoid, the improvement comprising:

a pager connected for electrical excitation to said battery including a receiver conformed to receive electromagnetic signals of a preselected signal combination and output means for generating an audio signal in response to the receipt of said signal combination;

a latching relay connected in said ignition circuit and to said output means for opening said ignition circuit upon the receipt of said signal combination; and

restoration means connected to said latching relay for closing said ignition circuit upon the manual articulation thereof.

2. Apparatus according to claim 1, further comprising:

a power supply connected between said battery and said said pager, for converting the electrical power output from said battery to the power levels of said pager.

3. Apparatus according to claim 2, wherein:

said restoration means includes a switch connected in circuit between said battery and said latching relay.

4. Apparatus according to claim 3, wherein:

said switch is a push-to-close momentary contact switch.

5. Apparatus according to claim 1, wherein:

said restoration means includes a switch connected in circuit between said battery and said latching relay.

6. Apparatus according to claim 5, wherein:

said switch is a push-to-close momentary contact switch.

7. Apparatus according to claim 6, wherein:

said switch is mounted in said vehicle in concealed placement.

8. A method for remotely disabling the starting sequence of a motor vehicle, comprising the steps of:

installing a pager in said vehicle in circuit with the ignition signal effecting said starting sequence;

placing a telephone call to the telephone facility of the vehicle user; and

transmitting a coded electromagnetic signal to said pager to effect a latched opening of said ignition signal upon the receipt of a negative response to said placement of said telephone call.

9. A method according to claim 8, comprising the further step of:

providing a secondary signal to unlatch and close said ignition signal.

10. A method according to claim 9, wherein:

said step of installing a pager includes the further step of connecting a latching relay in said ignition signal.

11. A method according to claim 10, comprising the further step of:

providing a secondary signal to said latching relay to unlatch and close said ignition signal.

12. In a motor vehicle characterized by a power plant, means for transferring motive power from said power plant to the undercarriage of said vehicle, a starter connected to said power plant for starting the operation thereof, a battery for storing an electrical charge, a solenoid selectively connecting said battery to said starter, and a manually operative ignition circuit for selectively operating said solenoid, the improvement comprising:

a pager connected for electrical excitation to said battery including a receiver conformed to receive electromagnetic signals of a preselected signal combination and output means for generating an audio signal in response to the receipt of said signal combination;

a latching relay connected in said ignition circuit and to said output means for opening said ignition circuit upon the receipt of said signal combination; and

restoration means connected to said latching relay for closing said ignition circuit upon the receipt of a successive electromagnetic signal.
