Vehicle security system using drivers license, time of day and passive tag
DCFirst Claim
1. For use with an automotive vehicle having a normally disabled ignition system, a system for selectively enabling said ignition system comprising:
- a driver'"'"'s license unique to a driver,encoded indicia on said driver'"'"'s license representative of the identity of the driver,means for reading said encoded indicia and for generating an identification signal representative thereof,memory means for storing data representative of authorized drivers for the vehicle,means for comparing said identification signal with said stored data in said memory means,means for enabling the vehicle ignition system when said identification signal corresponds to said stored data,a central station containing stored data representative of a plurality of driver'"'"'s licenses,a radio transmitter in the vehicle responsive only when said identification signal does not correspond to said stored data for transmitting a signal representative of the identification signal to the central station,means at said central station for receiving the representative signal and for comparing the received representative signal with stored data at the central station,means responsive to said comparison at said central station for transmitting an output signal by radio signal to the vehicle,a radio receiver at said vehicle for receiving said output signal from said central station and for enabling said ignition system in response thereto.

Abstract
A system is provided for use with an automotive vehicle having a normally disabled ignition system. Each driver license is encoded with indicia, such as a magnetic strip, indicative of the identity of the driver. This driver'"'"'s license is inserted into a reader container in the vehicle which then generates an identification signal representative of the identity of the driver'"'"'s license. A microprocessor then compares the identification signal from the driver'"'"'s license with prerecorded computer memory representative of the authorized driver(s) for the vehicle. When the driver'"'"'s license identification signal matches the stored data in memory, the microprocessor generates an output signal which enables the vehicle ignition system. Alternatively, when the driver'"'"'s license identification signal does not match the stored data, a radio transmitter transmits the driver'"'"'s license identification signal to a central station which compares this signal against stored data representative of a plurality of different drivers. If a match is obtained, the central station generates a radio signal back to a radio receiver at the vehicle which is read by the microprocessor and the microprocessor then generates an output signal which enables the ignition system. Alternatively, a timer is employed to allow operation of the vehicle only during prescribed time periods. In still a further modification, the system includes a radio receiver which receives a radio signal from a transmitter on an ankle bracelet worn by a person with a restricted drivers license. Once the receiver detects the radio signal from the bracelet, a microprocessor compares the current time with a time schedule containing time periods during which operation of the vehicle by the selective person is unauthorized. In the event that operation of the vehicle is unauthorized, the microprocessor generates a disabled signal which disables operation of the vehicle.

7. For use with an automotive vehicle having an ignition system, a system for permitting operation of the vehicle only during preset time periods consisting of:
-
a clock having an output signal indicative of the time of day, a timer circuit which receives said clock output signal and generates an ignition system enabling signal only when said clock signal is within a preset time period, means for connecting said ignition signal enabling signal to the vehicle ignition system to thereby enable the vehicle ignition only during said preset time period. - View Dependent Claims (8)
