Self-propelled vehicle power train evaluation
First Claim
Patent Images
1. A methed for testing a drive train of a self-propelled vehicle having a given weight utilizing a speed measuring radar directed toward said vehicle, comprising the steps of:
- operating said vehicle at full acceleration in one of the directions toward or away from said speed measuring radar to a given speed;
recording the signal produced by said radar representing speed of said vehicle versus time;
recording a signal indicative of the difference in weight of said vehicle under test and the weight of a "standard" vehicle against which the vehicle under test is being compared;
compensating the signal representing speed versus time of the vehicle under test by said weight indicating signal; and
comparing the compensated signal against a stored signal representing speed versus time of the said standard vehicle and producing a warning signal if the compensated signal differs from the standard signal representing the standard vehicle by a greater than a preselected amount.

Abstract
A self-propelled vehicle power train evaluation method employing a speed measuring radar directed toward a vehicle under test includes the steps of accelerating the vehicle toward the radar at full acceleration until a given speed is reached and recording the resulting speed versus time signal, optionally accelerating the vehicle away from the radar to thus produce an average speed versus time signal and comparing the thus produced speed versus time signal with a signal representing a standard vehicle of the type under test.
