  "textContent": "A torque ripple compensation device for a motor vehicle. The device includes an outer ring, an inner ring and a linkage. A first end portion of the linkage is connected a constraint and a second end portion of the linkage is connected to the inner ring and the outer ring. A torque in a rotating shaft is compensated, reduced and/or canceled using the device by identifying a torque spike, calculating the amplitude and/or phase of the torque spike, comparing the amplitude and/or phase of the torque spike to a pre-determined torque profile, calculating the amount of amplitude and/or phase shift from the pre-determined torque profile, determining the amount of eccentricity and/or elliptical trajectory needed to compensate, reduce and/or cancel the amount of phase and/or amplitude shift, and applying a force to the first end portion of the linkage to compensate, reduce and/or cancel the phase and/or amplitude shift calculated.",
