Benefits of technology

[0017]Thus, the subject system provides simple universal interface diagnostic conclusions similar to those available using older external diagnostic test equipment. Moreover, the subject interface provides a new level of diagnostics, more accurate levels of diagnosis and provides information roll up that is different that which was provided by the old pieces of test equipment.

Problems solved by technology

This concept of operation does not provide constant, real time monitoring because the test equipment had to be moved up to a vehicle each time testing was required.
This increases the logistical footprint because of added test equipment for maintainer to bring forward, as well as test equipment to be maintained over the extended life cycle of the platform.
Significantly, the special test equipment used in the past was only effective after a failure because on board vehicle health was not continually monitored.
Support of the specialized test equipment and personnel training increases cost of the support function and increased the logistics footprint.

Embodiment Construction

[0029]Referring to FIG. 1, a diagnostic connector assembly in the form of a diagnostic interface unit 10 eliminates the need for special test equipment while providing constant, real time monitoring. Diagnostic interface unit 10 includes a vehicle connector assembly 12 at one end of an outer cylindrical housing 14. Housing 14 slips over an inner cylindrical housing 16 that is apertured to expose a printed circuit board assembly 18 having contact pads connected to the connectors of connector assembly 12. An RS-422 or like connector 20 is used to connect the output of board 18 to a diagnostic computer 22.

[0030]The diagnostic interface unit approximates a modern engine sensing unit, and is adapted to be permanently installed on vehicles to provide constant engine status that allows health and status awareness, as well as, interactive diagnostics and prognostics. The diagnostic interface unit provides an analog interface with signal conditioning and switching, a digitizer with an analog...

Abstract

In a diagnostics system for use on vehicles, wherein the improvement comprises a connector assembly that translates diagnostic connector assembly signals into a digital format suitable for computer based analysis and fault diagnosis on an individual vehicle and vehicle fleet basis.

Description

RELATED APPLICATIONS[0001]This Application claims rights under 35 USC §119(e) from U.S. Application Ser. No. 61 / 154,588 filed Feb. 23, 2009, the contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to embedded vehicle diagnostic systems and more particularly to interface units supporting embedded diagnostics for existing analog diagnostic connector assemblies.BACKGROUND OF THE INVENTION[0003]In the past, diagnostic connector assemblies (DCAs) have been built into legacy military vehicles typically for associated analog sensor measurements from the engine or transmission. These diagnostic connectors were used in conjunction with specialized test equipment, in which the test equipment was typically brought out to a vehicle after a problem was encountered. When not in use, the diagnostic connector assembly is protected by a dust cover. This concept of operation does not provide constant, real time monitoring because the test e...
