Vibration detection and control for a vehicle drivetrain |
摘要 |
The present invention provides vibration control for a vehicle drivetrain. In one embodiment of the present invention, a vibration control method comprises generating a speed signal representing a rotational speed of the drivetrain. The method further includes half-wave rectifying the speed signal to generate a first signal. Also, the method comprises inverting the speed signal and half-wave rectifying the inverted signal to generate a second signal. Also, the method includes low-pass filtering the first signal to generate a third signal and low-pass filtering the second signal to generate a fourth signal. In addition, the method comprises selecting a minimum of the third and fourth signals to generate a fifth signal.
