System for conducting wireless communications between a vehicle computer and a remote system
First Claim
1. A system for conducting wireless communications between a remote system and a computer embedded within a vehicle, comprising:
- a first communications tag mounted to a vehicle and having a first computer configured for radio frequency communications;
a second communications tag mounted to a trailer and having a second computer configured for radio frequency communications;
a third computer embedded within said vehicle and electrically connected to said first computer;
a remote computer operable to establish a first radio frequency communications link with said first computer and to establish a second radio frequency communications link with said second computer, said remote computer extracting a serial number from said third computer via said first radio frequency communications link and extracting a trailer identification code from said second computer via said second radio frequency communications link, said remote computer comparing said serial number with said trailer identification code and transmitting an incompatibility signal via said first radio frequency communications link if said serial number and said trailer identification code are incompatible; and
means associated with said vehicle and responsive to said incompatibility signal for providing notification of said vehicle and trailer incompatibility.

Abstract
A system for conducting wireless communications between a vehicle computer and a remote system includes a passive radio frequency tag attached to a vehicle and electrically connected to at least one vehicle computer via an information bus, and a tag interface unit electrically connected to a remote computer system. The remote system is operable to control communications with one or more of the vehicle computers via a radio frequency link established between the tag and tag interface unit. The tag preferably includes a microprocessor-based computer electrically connected to the information bus, wherein the tag computer operates as a gateway for communications between the remote computer and any of the onboard vehicle computers including a vehicle/engine control computer, an interface module computer and a transmission control computer. The system preferably includes means for notifying the vehicle operator of various statuses of the communications being conducted, wherein the remote system is operable to control such notifying means.

4. A method of monitoring wireless communications between a computer embedded within a vehicle and coupled to a communications tag, and a remote computer coupled to a tag interface unit, the method comprising the steps of:
-
establishing a wireless communications link between the tag interface unit and the communications tag;
providing a serial number of the embedded computer to the remote computer via the wireless communications link; and
activating a first notification device associated with the vehicle if the remote computer determines that the serial number is included within a serial number database, wherein activation of the first notification device indicates that information exchange between the embedded computer and the remote computer is enabled. - View Dependent Claims (5, 6, 7)

8. System for monitoring wireless communications between a first computer embedded within a vehicle and a remote computer, the system comprising:
-
a communications tag mounted to said vehicle and coupled to said first computer;
a tag interface unit coupled to said remote computer, said remote computer establishing a wireless communications link between said tag interface unit and said communications tag, said remote computer determining whether a serial number of said first computer is included within a serial number database and transmitting a first command via said communications link if said serial number is included within said serial number database;
a first indicator associated with said vehicle; and
means responsive to said first command for activating said first indicator, wherein activation of said first indicator indicates that information exchange between said first computer and said remote computer is enabled. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
