Abstract

A security system for an automotive vehicle including a positioning device which, in cooperation with a Global Positioning System ("GPS") satellite network provides location information regarding the vehicle's position. The security system further includes a passive operator identification device having a first security code and a theft control unit including memory storing a second security code. The passive operator identification device and the theft control unit work together to ensure the vehicle operator is authorized to operate the vehicle. An event detector communicates with the theft control unit to provide an event signal associated with the vehicle such as vehicle movement. If an event signal is received by the theft control unit, and the first and second security codes are not equal, the theft control unit communicates the vehicle position as determined by the position detector to a monitoring station. The monitoring station could be the local police department, a security service firm, or the vehicle owner's residence, for instance.
