Abstract
A combined vehicle remote access, tire monitoring and vehicle immobilization system and method including a tire monitor for monitoring a tire parameter, the monitor including a transmitter for transmitting a radio frequency tire data signal, a vehicle access transmitter for transmitting a radio frequency vehicle access signal, and a vehicle activation transponder for receiving an interrogation signal and transmitting a vehicle activation signal for use in vehicle immobilization. The system and method further include a control module having a receiver and a controller for receiving and processing the tire data, vehicle access, and vehicle activation signals, and generating a display signal to display the information represented by the tire data signal, a vehicle access control signal to perform the vehicle access function, and a vehicle immobilization control signal to immobilize the vehicle if the controller fails to authenticate the vehicle activation signal.
