Method and system for remote interaction with a vehicle via wireless communication
First Claim
1. A method for disabling a vehicle via a wireless data link comprising the steps of:
- monitoring a circuit, having a first state for driving the vehicle, a second state for stating an engine of the vehicle, and a third state for turning the engine off;
receiving a message, transmitted over the wireless data link, at a telemetry system at the vehicle, the message comprising a command to disable the vehicle;
determining that the circuit is attempting to start the vehicle as a result of a transition of the circuit to the second state;
responsive to the receiving step and the determining step, interrupting the attempt to start the vehicle and causing the circuit to operate in the third state;
wherein power is removed from the telemetry system to conserve power if the circuit is set to the third state for a threshold amount of time and power is restored to the telemetry system if a security intrusion for the vehicle is detected.

Abstract
A telemetry system coupled to a vehicle can communicate with a remote site using the overhead control channels of a wireless network, such as a cellular mobile radiotelephone network. The telemetry system can monitor or control aspects of the vehicle'"'"'s operations based on remote user input. The telemetry system can take steps to reduce its consumption of electricity. When conditions warrant, the telemetry system can disable a driver'"'"'s attempt to start the vehicle. A relay can consume minimal electricity until an unauthorized driver attempts to start the vehicle, at which time the telemetry system can energize the relay to interrupt the starting sequence. The telemetry system can monitor a driver'"'"'s driving practices and report incidences that meet preset criteria, such as violating a speed limit for a selected amount of time or a crossing of a geographical boundary.

7. A method for operating a telemetry system connected to a vehicle, comprising the steps of:
-
determining whether a starter circuit of the vehicle is in a first state operative to start the vehicle, a second state operative to drive the vehicle, or a third state operative to turn the vehicle off; if the telemetry system receives an instruction to disable the vehicle, interrupting the starter circuit in response to the determining step if the starter circuit changes to the first state from one of the second state and the third state; measuring a time that the starter circuit is in the third state in response to determining that the starter circuit in is the third state; comparing the measured time to a threshold; if the measured time is greater than the threshold, disconnecting the telemetry system from a source of electricity; and in response to detecting a security intrusion for the vehicle, reconnecting the disconnected telemetry system to the source of electricity. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method for conserving power consumption of a telemetry system connected to a vehicle, comprising the steps of:
-
determining whether an ignition switch of the vehicle is in a first state for operating the vehicle or a second state for storing the vehicle; if the ignition switch is determined to be in the second state, timing an interval that the vehicle is in the second state; comparing the timed interval to a threshold; disconnecting the telemetry system from a power source if the timed interval exceeds the threshold; and if a security intrusion for the vehicle is detected, reconnecting the telemetry system to the power source. - View Dependent Claims (14, 15, 16, 17)
