Method and systems for detecting an unauthorized use of a vehicle by an authorized driver

A method for detecting an unauthorized use of a vehicle in the absence of GPS location information, the method comprising:

• receiving vehicle component condition data for one or more vehicle components;
• receiving actual or estimated historical vehicle component condition data for the one or more vehicle components at a key-on;
• comparing the vehicle component condition data to the actual or estimated historical vehicle component condition data having been stored at a key-off;
• determining if an inconsistency exists between the vehicle component condition data and the actual or estimated historical vehicle component condition data based on the comparison;
• upon determining the inconsistency, generating an alert signal signifying an unauthorized use;
• and
• transmitting at least one of the alert signal and the vehicle component condition data to a remote terminal to alert a user of the unauthorized use.

A method comprising:

• receiving at least one key-on and at least one key-off event signal;
• receiving key-on vehicle system state non-location data and actual/estimated key-off vehicle system state non-location data upon receipt of the respective event signals;
• comparing the key-on and key-off system state non-location data;
• identifying a data inconsistency based on the comparison;
• generating an alert signal based on the inconsistency;
• and
• transmitting the vehicle data or the alert signal to a remote terminal.
