Japanese Patent JP7161912
Kind Code:

Abstract:
A system includes an input device that receives desirable performance characteristics of a vehicle a diagnostic processor that receives vehicle test data, and determines undesirable vehicle performance data points by comparing the desirable vehicle performance characteristics to the test data. The diagnostic processor also determines undesirable system data points that correspond to likely causes of the undesirable vehicle performance data points by comparing the desirable system performance characteristics to the test data, and determines undesirable component data points that correspond to likely causes of the undesirable system data points by comparing the desirable component performance characteristics to the test data. The diagnostic processor also generates an analysis of the undesirable component data points including selected component data points of the undesirable component data points that are likely causes of the undesirable vehicle performance data points, and controls an output device to output the analysis of the undesirable component data points.
