Abstract:
1. A method of detecting and correcting power train oscillation in a vehicle provided with a prime mover which rotates at a speed ω, at least one powered wheel, and a drive shaft positioned to drive the at least one powered wheel, the method comprising: determining, by an automated processor, an effect of a spring release force imparted by the driveshaft, the determining made when both of conditions (a) and (b) are detected: (a) for a predetermined number of times an amplitude of a change in cyclic variation S in the rotation speed ω of the prime mover is alternately above a positive threshold value Th (b) all consecutive upward crossings of the positive threshold value Th controlling the primer mover to correct the power train oscillation, when the effect of the spring release force is determined.
