Abstract
An electromechanical camshaft phaser () comprises a setting gear () and an electric motor (), which is controlled by means of an electric-motor control unit (). Data concerning the operation of the electric motor () including position changes of its motor shaft are transferred via a data bus () from the electric-motor control unit () to an engine control unit () of the internal combustion engine () comprising the camshaft phaser (). In addition, recurring time signals are transferred from the electric-motor control unit () to the engine control unit () via a separate line (), by which harder real-time requirements are met than by the data bus (). The time signals are used to generate a time difference signal in the engine control unit () by comparison with the data received by the engine control unit (), which time difference signal is fed back to the electric-motor control unit () via the data bus () and is used there to synchronize the electric-motor control unit () with the engine control unit ().
