Verification of installation of vehicle starter disable and enable circuit
First Claim
1. A method for verifying that a vehicle tracking device has been correctly connected to a vehicle ignition, a vehicle starter motor, and a starter relay, wherein the starter relay has a starter disabled switch position and a starter enabled switch position, the method comprising:
- (a) transmitting a starter disable command to the vehicle tracking device via a wireless communication network;
(b) in response to the starter disable command, the vehicle tracking device setting a starter relay control connection to a first state to control the starter relay to direct a starting voltage from the vehicle ignition to the starter disabled switch position;
(c) while the vehicle ignition is in a start position, monitoring;
the starter relay control connection;
a first voltage level on a first connection to the starter disabled switch position;
a second voltage level on a second connection to the starter enabled switch position; and
a third voltage level on an ignition connection to the vehicle ignition;
(d) generating a first report message indicating that the vehicle tracking device has been correctly connected based on the starter relay control connection being in the first state, the first voltage level being the starting voltage, the second voltage level not being the starting voltage, and the third voltage level being an ignition-on voltage; and
(e) transmitting the first report message to a mobile communication device.

Abstract
A verification procedure is performed when a tracking device is newly installed in a vehicle. The procedure involves transmitting a command to the tracking device to either disable or enable the vehicle starter. The installer is then prompted to engage the starter to start the vehicle. The tracking device then monitors the voltages on the vehicle'"'"'s ignition wire and starter disable and starter enable wires going to a starter relay. The tracking device also monitors the state of a starter relay control wire. Measurement of the proper voltages on these wires provides verification that the tracking device has been connected properly. Continuing to monitor these voltages after installation provides an indication when a driver engages the starter in an attempt to start the vehicle.

6. A vehicle tracking device for installation in a vehicle having an ignition system and a starter relay connected to the ignition system for disabling and enabling a starter of the vehicle, the vehicle tracking device comprising:
-
a location sensor that generates location information indicating a location of the vehicle tracking device; a wireless transceiver that wirelessly communicates information between the vehicle tracking device and a wireless communication network; a starter disable/enable circuit that monitors connections between the vehicle tracking device and the ignition system of the vehicle and generates state information based on the connections, wherein the connections include an ignition connection, a starter relay control connection, a first connection to a starter disabled switch position of the starter relay, and a second connection to a starter enabled switch position of the starter relay, wherein states of the starter relay control connection comprise; a first state in which the starter relay directs a starting voltage from the vehicle ignition system to the starter disabled switch position; and a second state in which the starter relay directs the starting voltage from the vehicle ignition system to the starter enabled switch position; a processor that receives the state information from the starter disable/enable circuit and generates a report message indicating that the vehicle tracking device has been correctly connected based on; the starter relay control connection being in the first state, the first connection receiving the starting voltage, the second connection not receiving the starting voltage, and the ignition connection receiving an ignition-on voltage;
orthe starter relay control connection being in the second state, the second connection receiving the starting voltage, the first connection not receiving the starting voltage, and the ignition connection receiving an ignition-on voltage; and the wireless transceiver for communicating the report message via the wireless information network. - View Dependent Claims (7, 8)

9. An apparatus for verifying that a vehicle tracking device has been correctly connected to a vehicle ignition, a vehicle starter motor, and a starter relay, wherein the starter relay has a starter disabled switch position and a starter enabled switch position, the apparatus comprising:
-
a central server that is in communication with the vehicle tracking device via a wireless communication network, the central server executing instructions to; send a starter disable command to the vehicle tracking device via the wireless communication network; and send a message via the wireless communication network to a mobile communication device of a person who is tasked with verifying that the vehicle tracking device has been correctly connected to the vehicle ignition, which message prompts the person to put the vehicle ignition in a start position; and the vehicle tracking device comprising; a location sensor that generates location information indicating a location of the vehicle tracking device; a wireless transceiver that receives the starter disable command via the wireless communication network; a starter disable/enable circuit that, in response to the starter disable command, sets a starter relay control connection to a first state in which the starter relay directs a starting voltage from the vehicle ignition to the starter disabled switch position of the starter relay, and while the vehicle ignition is in the start position, monitors connections between the vehicle tracking device and the ignition system of the vehicle and generates state information based on the connections, wherein the connections include an ignition connection, the starter relay control connection, a first connection to the starter disabled switch position of the starter relay, and a second connection to the starter enabled switch position of the starter relay; and a processor that receives the state information from the starter disable/enable circuit and generates a first report message indicating that the vehicle tracking device has been correctly connected based on the starter relay control connection being in the first state, the first connection receiving the starting voltage, the second connection not receiving the starting voltage, and the ignition connection receiving an ignition-on voltage, wherein the wireless transceiver communicates the first report message via the wireless information network. - View Dependent Claims (10, 11)
