Voice actuated vehicle security system with starting system interlock and automatic arming feature
First Claim
1. A voice actuated vehicle security system, comprising:
- a microphone for transducing spoken expressions into electronic signals corresponding to said spoken expressions, said microphone being adapted for mounting inside a vehicle;
an audio input circuit for conditioning said electronic signals from said microphone;
a memory storage for storing speech templates;
means for selectively generating an input signal for use to passively arm said vehicle security system, the generation of said input signal being indicative of at least one predetermined condition associated with the vehicle;
a processor for processing said conditioned electronic signals and for comparing the processed, conditioned electronic signals with said speech templates stored in said memory storage, said processor generating a disarming signal when said processed, conditioned electronic signals are substantially similar to one of said speech templates, said processor monitoring said input signal and producing an arming signal when said input signal indicates the presence of said at least one predetermined condition; and
an electrical interlock mechanism operated by said processor, said electrical interlock mechanism for placement in series with the ignition system of the vehicle to positively inhibit the engine of the vehicle from running by preventing the spark-generating ignition system of the vehicle from operating when said processor produces said arming signal, said electrical interlock mechanism allowing the vehicle to be started when said processor produces said disarming signal.

Abstract
An improved vehicle security system is disclosed in which different modes of arming and disarming the system are utilized. The system uses an arming feature to disable operation of the vehicle which is initiated by the vehicle ignition switch being turned off following which one or more doors of the vehicle are opened. The system also uses a voice actuated alarm deactivation procedure in which operation of the vehicle is enabled following voice identification of a spoken password as belonging to an authorized individual. The vehicle security system uses a positive interlock in which both the vehicle'"'"'s starting system and its ignition system are disabled when the system is armed.
