Abstract

A vehicle monitoring system is described having an arrangement installed within a vehicle, wherein the system includes an external data terminal for communicating information to a remotely located base station. The arrangement includes a plurality of communication modules, each being capable of communicating messages associated with performance of the vehicle; a data bus member for electrically intercoupling the plurality of communication modules and for receiving the communicated messages therefrom; a driver interface module for transmitting messages to and for receiving messages from a vehicle operator; and a recorder coupled to the data bus member for recording information associated with performance of the vehicle which has been transmitted over the data bus member by the plurality of communication modules, coupled to the driver interface module via a second data bus member for transferring messages therebetween. The external data port is provided by the recorder and is used for communicating messages with the base station, preferably over an RF link.

Claims

1. A vehicle monitoring arrangement, comprising:

a plurality of communication modules, each being capable of communicating messages associated with performance of the vehicle;

a vehicle sensor for indicating a vehicle condition parameter;

a data bus member for electrically intercoupling said plurality of communication modules and the vehicle sensor, and for receiving said communicated messages therefrom;

a recording module having two data paths for receiving information associated with performance of the vehicle, said two data paths including a first data path coupled to said data bus member for receiving information which as been transmitted over the data bus member by said plurality of communication modules and including a second data path for receiving messages directly from the vehicle sensor; and

remote programming means for communicating with said recording module, and for selectively programming the recording module to receive and monitor indications from the vehicle sensor using one of the two data paths.

2. A vehicle monitoring arrangement, according to claim 1, further including a sensor interface module, coupled to the vehicle sensor and the data bus member, for adapting the vehicle sensor to communicate on the data bus member.

3. A vehicle monitoring arrangement, according to claim 1, wherein said remote programming means is RF coupled to said recording module.

4. A vehicle monitoring arrangement capable of communicating information with a base station and having a plurality of communication modules, each capable of communicating messages associated with performance of the vehicle over a first data bus member in the form of short data bursts, the arrangement, comprising:

a driver interface module having a display for transmitting messages to a vehicle operator and a keyboard for receiving messages from the vehicle operator;

an RF unit for transmitting messages to and receiving messages from the base station; and

central control means;

coupled to the data bus member and having a microcomputer and memory for recording information associated with performance of the vehicle which has been transmitted over the data bus member by the plurality of communication modules,

coupled to said driver interface module via a second data bus member and having a high speed interface circuit for transferring messages therebetween in the form of relatively long data streams and at relatively high speeds, and

including an external data port capable of direct electrical connection with the base station for communication therewith, and capable of communication with the base station through the RF unit.
