System and method for tire pressure monitoring including vehicle immobilization
First Claim
1. In a vehicle having an engine and a plurality of tires, each tire having a transmitter mounted therein for transmitting wireless tire information signals, a system for remote monitoring of tire pressure and for remote immobilization of the vehicle comprising:
- a receiver for mounting on the vehicle, the receiver for receiving both the tire information signals transmitted by the transmitters and a remote wireless encrypted vehicle immobilization signal including an authentication code; and
a controller for mounting on the vehicle and to be provided in communication with the receiver, the controller for processing the tire information signals received by the receiver to convey tire pressure information to a vehicle occupant, and for processing the encrypted vehicle immobilization signal received by the receiver to determine if the immobilization signal is valid based on the authentication code and to generate a control signal for use in immobilizing the vehicle if the immobilization signal is determined valid.

Abstract
A system and method for remote monitoring of vehicle tire pressure and remote vehicle immobilization. Transmitters are provided for mounting in the vehicle tires for transmitting wireless tire information signals. A receiver is provided for mounting on the vehicle for receiving both the tire information signals transmitted by the transmitters and a remote wireless encrypted vehicle immobilization signal including an authentication code. A controller is provided for mounting on the vehicle in communication with the receiver. The controller processes the tire information signals received by the receiver to convey tire pressure information to a vehicle occupant, and processes the encrypted vehicle immobilization signal received by the receiver to determine if the immobilization signal is valid based on the authentication code and to generate a control signal for use in immobilizing the vehicle if the immobilization signal is determined valid.
