阀正时控制装置
摘要：
一种阀正时控制装置(VT)包括：与内燃机(E)的曲轴(1)同步旋转的驱动侧旋转构件(21)；与内燃机的凸轮轴(7)一体地旋转的从动侧旋转构件(22)；相位调节机构，利用该相位调节机构，驱动侧旋转构件和从动侧旋转构件围绕旋转轴(X)的相对旋转相位由电动机(M)的驱动力设定；获取相对旋转相位的相位感测部(PS)；和控制电动机以基于相位感测部的获取结果来设定相对旋转相位的相位控制部(53)。相位感测部包括凸轮角感测器(17)、参考确定感测器(16)和模式存储单元(52a)。阀正时控制装置还包括相位获取部(52)。
摘要（英）：

A valve timing controller (VT) includes: a driving side rotation member (21) that rotates synchronously with a crankshaft (1) of an internal combustion engine (E); a driven side rotation member (22) that integrally rotates with a cam shaft (7) of the internal combustion engine (E); a phase regulating mechanism with which a relative rotation phase of the driving and driven side rotation members around a rotation axis is set by a driving force of an electric motor (M); a phase sensing portion (PS) that acquires the relative rotation phase; and a phase controlling section (53) that controls the electric motor to set the relative rotation phase based on an acquisition result by the phase sensing portion. The phase sensing portion includes a cam angle sensor (17), a reference determination sensor (16), and a pattern storage unit (52a). The valve timing controller further includes a phase acquisition portion (52).
