Electronic tag including RF modem for monitoring motor vehicle performance with filtering
First Claim
1. An apparatus for bi-directional communication between a host and a motor vehicle, the motor vehicle including an on board computer system having a bus for communicating with a plurality of motor vehicle systems, the apparatus comprising:
- an electronic tag coupled to the bus, the tag includinga transceiver for transmitting data to and receiving data from the host;
a memory for storing bus requests and bus response data;
a decoder for decoding requests from the host;
a bus interface for reading data from and writing data to the bus, the bus interface extracting responses from the bus responsive to requests from the host, the responses being stored in the memory;
a controller responsive to write requests from the host to transfer data to the bus interface and responsive to read requests from the host to transfer data stored in memory back to the host; and
a filter operable to filter responses received from the bus and a filter database, the filter database including one or more screening parameters for screening responses received from the bus.

Abstract
A method and apparatus for communicating between a host and a motor vehicle, the motor vehicle including an on board computer system having a bus for communicating with a plurality of motor vehicle systems. The apparatus includes an electronic tag having a transceiver for transmitting data to and receiving data from the host, a memory for storing bus requests and bus response data, a decoder for decoding requests from the host, a bus interface for reading data from and writing data to the bus, a controller and a filter. The bus interface extracts responses from the bus responsive to requests from the host. The responses may be stored in the memory. The controller is responsive to write requests from the host to transfer data to the bus interface and responsive to read requests from the host to transfer data stored in memory back to the host. The filter is operable to filter responses received from the bus and includes a filter database. The filter database includes one or more screening parameters for screening responses received from the bus.

7. A system for remotely monitoring motor vehicle performance comprising:
-
a system bus resident on the motor vehicle for communicating with a plurality of motor vehicle systems; a remote reader for generating host requests for extracting data from one or more motor vehicle systems; an electronic tag coupled to the system bus including a transceiver for transmitting data to and receiving data from the remote reader; a memory for storing bus requests and bus response data; a decoder for decoding requests from the remote reader; a bus interface for reading data from and writing data to the system bus, the bus interface extracting responses from the system bus responsive to requests from the remote reader, the responses being stored in the memory; a controller responsive to write requests from the remote reader to transfer data to the bus interface and responsive to read requests from the remote reader to transfer data stored in memory back to the remote reader; and a filter operable to filter responses received from the bus a filter database, the filter database including one or more screening parameters for screening responses received from the bus. - View Dependent Claims (8, 9, 10, 11, 12)
