AI Technical Summary

Benefits of technology

The invention is a new algorithm called PRDICTR that improves fault detection in computer systems. The algorithm is embedded in a microprocessor and runs at the point of performance, making it faster and more accurate than previous prognostication algorithms. It assigns a probability to the input and output, making it easier to determine if the system is performing correctly. This allows for faster and more accurate fault detection without requiring additional infrastructure.

Problems solved by technology

This is of course computationally intense.

Embodiment Construction

[0016]As can be seen from FIG. 1, the prior PRDICTR algorithms are utilized on Class 8 vehicles those such as vehicle 10 that are 30,000 plus gross weight vehicles, in which the on-board PRDICTR algorithm 12 is run on an embedded computer 14 within the vehicle.

[0017]The size and computational capabilities of computer 14 are not those associated with microprocessors, but rather these computers have massive computational power, unsuitable for use in light vehicles due to size and complexity.

[0018]Referring to FIG. 2, a light vehicle 20 includes a microprocessor with a light version of the PRDICTR algorithm as illustrated at 22, with the microprocessor being embedded in the vehicle. The algorithm takes inputs from selected vehicle sensors and provides prognostic predications of vehicle failure modes. It is the purpose of the subject invention to provide a PRDICTR Light version of at prognostication algorithm to permit the use of microprocessors by eliminating running massive numbers of...

Description

RELATED APPLICATIONS[0001]This Application is a continuation of U.S. application Ser. No. 12 / 807,923 filed Sep. 16, 2010 and claims rights under 35 USC ยง119(e) from U.S. Application Ser. No. 61 / 342,133 filed Apr. 9, 2010, the contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]This invention relates to the provision of on-board diagnostics for vehicle fleet maintenance and more particularly to the embedding of a microprocessor programmed with a prognostication algorithm on a vehicle.BACKGROUND OF THE INVENTION[0003]As discussed in U.S. patent application Ser. No. 12 / 548,683 by Carolyn Spier filed on Aug. 27, 2009, assigned to the assignee hereof incorporated herein reference, prognostication algorithms have been utilized to predict faults in the operation of vehicles. More importantly the prognostics algorithm, referred to herein as the PRDICTR algorithm, is used to analyze data from vehicles at a central or remote location where the algorithms can be ...
