Abstract

Automobile ignition inhibit will be used in an RF system with the purpose of inhibiting an automobile and its mobile radio after an automobile has been reported stolen. The dispatch operator at a main site will send a RF command to the mobile radio. Upon receipt of this command, the mobile radio will send an acknowledge- ment back to the dispatch operator. Then the radio will immediately disable the automobile's ignition. The automobile is not capable of being restarted while the inhibit command is active. The mobile radio's micro- phone, speaker and display will also be disabled. The mobile radio will be capable of receiving information from the dispatch operator while the inhibit command is active. Once the automobile has been recovered, the dis- patch operator can send a RF command to disable inhibit operation in the mobile radio. This will allow the auto- mobile and the mobile radio to return to normal operation.

  Automobile ignition inhibit will be used in an RF system with the purpose of inhibiting an automobile and its mobile radio after an automobile has been reported stolen. The dispatch operator at a main site will send a RF command to the mobile radio. Upon receipt of this command, the mobile radio will send an acknowledge- ment back to the dispatch operator. Then the radio will immediately disable the automobile's ignition. The automobile is not capable of being restarted while the inhibit command is active.

Once the automobile has been recovered, the dis- patch operator can send a RF command to disable inhibit operation in the mobile radio. This will allow the auto- mobile and the mobile radio to return to normal operation.

  The mobile radio will be part of the automobile's ignition system using current automobile security sys- tem technology. The mobile radio's ON/OFF opera- tion will be slaved to the ignition's status except when its switch is in the 'OFF' position, similar to an AM/FM car radio. When the inhibit command is enabled, the radio will have the ability to tom the ignition off while the key is still in the 'ON' position. The radio's receiver remai...
