Synchronization device for an engine

Method for synchronizing shafts in an engine during an engine start-up phase or an engine stopped phase, comprising:

• determining an angular position of a first shaft by a first active sensor;
• determining an angular position of a second shaft by a second active sensor;
• or
• determining a phase position between the first shaft and the second shaft;
• wherein the first active sensor and the second active sensor are adapted to recognize a rotational speed of a shaft at least between a reference value for the rotational speed of the shaft and a standstill of the shaft;
• wherein the first active sensor and the second active sensor are adapted for recognizing a reversal of a rotational direction of the shaft;
• providing information on the angular position of the first shaft to a control device;
• 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;
• and
• providing a control signal for setting a given phase difference between the first shaft and the second shaft.

Computer-readable memory medium on which a program is stored for synchronizing shafts in an engine during an engine start-up phase or an engine stopped phase, wherein the program controls the following processing steps executed by a processor:

• determining an angular position of a first shaft by a first active sensor;
• determining an angular position of a second shaft by a second active sensor;
• or
• determining a phase position between the first shaft and the second shaft;
• wherein the first active sensor and the second active sensor are adapted to recognize a rotational speed of the shaft at least between a reference value for the rotational speed of the shaft and a standstill of the shaft;
• wherein the first active sensor and the second active sensor are adapted to recognize a reversal of a rotational direction of the shafts;
• providing information on the angular position of the first shaft to a control device;
• 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;
• and
• providing a control signal for setting a given phase difference between the first shaft and the second shaft.
