MOTOR CONTROL STRATEGY FOR A HYDRAULIC CAMSHAFT ADJUSTER HAVING A MECHANICAL CENTRAL LOCK

摘要

The present invention at least one rotor (2) and the stator (3) having, between them the hydraulic into pressurizable chamber (A) and the chamber (B) is provided that is, the mechanical center of the locking unit having a hydraulic camshaft adjuster (1) It relates to an engine control strategy for. In the rotor (2) is provided with a locking piston (6 to 10) for the mechanical locking center supported so as to be movable in the axial direction. One or more defined zones (zone definition) stored in the angular position obtained at least one signal, the engine control device for "lighting-out" the current angular position of the signal and the camshaft adjuster (1) (angular position) when the engine stops compare, and the controllable electrical solenoid valve and hydraulic control system in which current is supplied by the engine control unit is provided to form a control command from it to pass to the electric solenoid valve.
