1. A remote engine start confirmation and vehicle monitoring and control system for use in a vehicle having a battery, a starter, and an engine having a flywheel attached thereto, the system including a transmitter and a controller capable of receiving and processing signals from the transmitter to initiate a remote engine start procedure, the controller comprising:

  • a) means for detecting a first pulsed voltage pattern and a second pulsed voltage pattern across the resistance of the battery during a remote engine start procedure, the second pulsed voltage pattern having a higher frequency than the first pulsed voltage pattern;

    b) means for signaling the disengagement of the starter from the flywheel after a detection of the termination of the first pulsed voltage pattern and the start of the second pulsed voltage pattern; and

    c) means for initiating the monitoring of a vehicle condition after the detection of the termination of the first pulsed voltage pattern and the start of the second pulsed voltage patternwhereby when a user remotely starts the vehicle engine via the transmitter, the means for detecting a first pulsed voltage pattern and a second pulsed voltage pattern across the resistance of the battery detects the termination of the first pulsed voltage pattern and the start of the second pulsed voltage pattern indicating that the engine has been started, the means for signaling the disengagement of the starter from the flywheel sends a signal to disengage the starter from the flywheel, and the means for initiating the monitoring of a vehicle condition initiates the monitoring of a vehicle condition.
