摘要： A valvetrain for an internal combustion engine has a camshaft that can be rotated in a direction of rotation around an axis of rotation, at least two cam pieces arranged on the camshaft which each have at least two cams for actuating a respective gas exchange valve and which are rotationally fixedly connected to the camshaft, and an actuator via which the cam pieces can be shifted in the axial direction of the camshaft. A first of the cam pieces has a first rib protruding outwardly from a first base body of the first cam piece in the radial direction of the camshaft and the second cam piece has a second rib protruding outwardly from a second base body of the second cam piece in the radial direction of the camshaft.

摘要： A valve drive device, in particular for an internal combustion engine, includes a support element fixed to a housing and at least one axially shiftable cam unit allocated to a valve. The cam unit has at least three cam tracks. At least one switching unit which is a displacement body is provided to displace at least one part of the cam unit in the direction of a first actuation direction for axial shifting. The displacement body displaces at least one part of the cam unit in the direction of a second actuation direction opposing the first actuation direction.

摘要： A method for controlling at least one component of a motor vehicle, involves determining a current driving profile of the motor vehicle using at least one sensor present in the motor vehicle and comparing the current driving profile to a stored reference driving profile. At least two different components are simultaneously controlled depending on a result of this comparison.

摘要： A valve drive device has a camshaft which includes a shaft element and a cam piece which can be driven by the shaft element and a first cam effecting a first stroke of a valve and a second cam effecting a second stroke of the valve, and is displaceable in the axial direction of the camshaft relative to the shaft element between a first position, in which the valve can be actuated by the first cam, and a second position in which the valve can be actuated by the second cam, and has an electrically controllable actuator via which the cam piece is displaceable relative to the shaft element in the axial direction as a result of an electrical control of the actuator. The actuator pushes the cam piece alternately back and forth between the positions in the case of successive electrical controls occurring with the same polarity.
