Abstract: An engine control module includes at least one high side driver connected to at least one intake camshaft actuator and at least one exhaust camshaft actuator. A plurality of low side drivers is connected to the at least one intake camshaft actuator and the at least one exhaust camshaft actuator. A sliding camshaft control module selectively actuates the at least one high side driver and the plurality of low side drivers based on a status associated with the at least one intake camshaft actuator and/or the at least one exhaust camshaft actuator.

Abstract: A camshaft assembly can control the motion of the intake or exhaust valves of an internal combustion engine and includes a base shaft extending along a longitudinal axis. The camshaft assembly further includes an axially movable structure mounted on the base shaft and axially movable relative to the base shaft. The axially movable structure includes a plurality of lobe packs. Each lobe pack includes a plurality of cam lobes. The axially movable structure includes a barrel cam defining a control groove. The camshaft assembly additionally includes an actuator including an actuator body and a pin movably coupled to the actuator body between a retracted position and an extended position. The axially movable structure can move axially relative to the base shaft when the base shaft rotates about the longitudinal axis and the pin is in the extended position and at least partially disposed in the control groove.
Abstract translation: 凸轮轴组件可以控制内燃机的进气门或排气门的运动,并且包括沿着纵向轴线延伸的基轴。 凸轮轴组件还包括可轴向移动的结构,其安装在基座轴上并相对于基轴可轴向移动。 可轴向移动的结构包括多个叶片组。 每个凸角组件包括多个凸轮凸角。 轴向可移动结构包括限定控制槽的筒形凸轮。 凸轮轴组件另外包括致动器,该致动器包括致动器主体和在缩回位置和延伸位置之间可动地联接到致动器本体的销。 当基轴围绕纵向轴线旋转并且销处于伸出位置并且至少部分地设置在控制槽中时,可轴向移动的结构可相对于基部轴线轴向移动。
