Abstract

Active diagnosis of current operating and potential fault conditions in the operation of the vehicle is implemented using a diagnostic controller interoperating with an on-board vehicle control system as installed within a vehicle. The diagnostic controller supports autonomous execution of diagnostic tests initiated dependent on the operational state of the vehicle. The control system includes a diagnostics control manager that autonomously selects test routines for execution at defined operational states, including in-service operational states, a monitor, responsive to sensor data retrieved in real-time from the on-board vehicle control system, operative to detect a current instance of the in-service operational state of the vehicle, and a diagnostic test scheduler operative to initiate execution of the diagnostic test routine upon detection of the current instance of the in-service operational state of the vehicle.

a diagnostic controller, coupleable to an on-board vehicle control system installed within a vehicle, operative to exchange commands and data with said on-board vehicle control system, said diagnostic controller implementing a control system providing for the autonomous execution of diagnostic tests dependent on the operational state of said vehicle, said control system including;

I) a diagnostics control manager operative to select a diagnostic test routine for execution by said diagnostic controller, wherein said diagnostic test routine includes one or more predefined commands that, by execution, are issued to said on-onboard vehicle control system, said diagnostics control manager being further operative to define an in-service operational state at which to execute said diagnostic test routine;

ii) a monitor, responsive to sensor data retrieved in real-time from said on-board vehicle control system, operative to detect a current instance of said in-service operational state of said vehicle; and

iii) a diagnostic test scheduler, responsive to said monitor, operative to initiate execution of said diagnostic test routine upon detection of said current instance.

2. The diagnostics control system of claim 1 wherein said control system includes a test queue, wherein said diagnostics control manager is operative to post said diagnostic test routine to said test queue pending occurrence of said in-service operational state and wherein said diagnostic test scheduler is operative to select said diagnostic test routine from said test queue upon detection of said current instance, whereby execution of said diagnostic test routine is deferrable until specific vehicle in-service conditions appropriate for conducting the diagnostic test exist.

3. The diagnostics control system of claim 2 wherein said diagnostics control manager, responsive to sensor data retrieved from said on-board vehicle control system, is operative to autonomously select said diagnostic test routine, from among a plurality of diagnostic test routines, for execution.

4. The diagnostics control system of claim 3 wherein said control system further includes an expert system responsive to sensor data retrieved from said on-board vehicle control system, wherein said expert system is operative to autonomously command selection by said diagnostics control manager of said diagnostic test routine, from among a plurality of diagnostic test routines, for execution.

5. The diagnostics control system of claim 4 wherein said diagnostic controller includes first and second components, wherein said first component is installable on-board said vehicle coupled to said on-board vehicle control system to provide for the exchange of commands and data with said on-board vehicle control system, said first diagnostic controller component including a first wireless transceiver, and wherein said second component is implemented as a hand portable device including a display coupled to said control system to display data representative of the results of the execution of said diagnostic test routine following from detection of said current instance, said second component including a second wireless transceiver through which said second component is interoperable with said first component for the exchange of commands and data.

6. A method of autonomously analyzing the operation of a vehicle having an on-board vehicle control system implementing a network of sensors and controls with respect to a plurality of vehicle components for managing the operation of said vehicle, said method comprising the steps of:

a) autonomously determining, by a diagnostic controller coupleable to said on-board vehicle control system for the exchange of commands and data, a diagnostic test routine to be executed by said diagnostic controller at a specified operating state of said vehicle, wherein execution of said diagnostic test routine provides for the communication of a sequence of one or more commands to said on-board vehicle control system, and wherein said specified operating state is one of a plurality of predetermined operating states including in-service operating states;

b) receiving, by said diagnostic controller, a real-time stream of sensor data reflective of the operating state of said vehicle;

c) evaluating, by said diagnostic controller, said real-time stream of sensor data to identify an occurrence of said specified operating state;

d) executing, upon identification of said occurrence of said specified operating state, said diagnostic test routine; and

e) analyzing, by said diagnostic controller, said real-time stream of sensor data to identify a faulting component.

7. The method of claim 6 wherein said step of analyzing provides information potentially reflective of the identity of said faulting component to said step of autonomously determining and wherein said step of autonomously determining provides for the repeated determining to execute one or more of a plurality of diagnostic test routines to enable said step of analyzing to confirm the identity of said faulting component.
