Patent ID: 7912624

Claim:
Synchronization device for a camshaft adjuster, comprising: a control device; a first active sensor for determining an angular position of a first shaft; a second active sensor for determining an angular position of a second shaft or for determining a phase position of the first shaft relative to the second shaft; a third sensor for determining an angular position of a third shaft; wherein the first active sensor is adapted to provide information on the angular position of the first shaft to the control device; wherein the second active sensor is adapted for providing information on the angular position of the second shaft or the phase position between the first shaft and the second shaft to the control device; wherein the third sensor is adapted to provide information on the angular position of the third shaft to the control device; wherein the first active sensor and the second active sensor are adapted to recognize a rotational speed of the shaft at least between one reference value for a rotational speed of the shaft and a standstill of the shaft; and wherein the first active sensor and the second active sensor are adapted to recognize a reversal of a rotational direction of the shaft; and wherein the control device is adapted to provide a control signal for setting a given phase difference between the first shaft and the second shaft.
