    • A variable valve timing adjuster with an intermediate lock mechanism learns a lock position and a lock release control. During a lock control, a learning of the lock position from a real camshaft phase is repeated to update the learned value, and the learning is ended when it is judged that the learned values have converged. At this time, when the learned values of the lock position do not converge even if the number of learning of the lock position exceeds a predetermined value, an insufficient lock state is judged, and the learned value of the lock position is set to an initial value or the learned value at the previous lock control thereby to make a lock release control. During the lock release control, on the other hand, the control (or the lock release control) of a hydraulic control valve is learned. When the lock cannot be released during the lock release control, the lock release control (or the learned value) is corrected in a direction to facilitate the lock release. When the correction of the lock release control is repeated a predetermined or more number of times or when the lock release control goes outside a predetermined range, the lock release failure is judged.
    • 具有中间锁定机构的可变气门正时调节器学习锁定位置和锁定解除控制。 在锁定控制期间,重复从真实的凸轮轴相位获知锁定位置以更新学习值,并且当判断学习值已经收敛时,学习结束。 此时,即使锁定位置的学习次数超过规定值,锁定位置的学习值也不会收敛,则判断为锁定不足状态,将锁定位置的学习值设定为初始值 值或前次锁定控制的学习值,从而进行锁定释放控制。 另一方面,在锁定释放控制期间,学习液压控制阀的控制(或锁定释放控制)。 在锁定释放控制过程中无法释放锁定时,将锁定释放控制(或学习值)向一个方向进行校正,以便于锁定释放。 当锁定释放控制的校正重复预定次数或更多次时,或当锁定解除控制超出预定范围时,判断锁定解除失败。

CONSTITUTION: A linear actuator(10) comprises a cylinder body(12), a slide table(14), a cylinder tool, and a locking tool(20). The cylinder body is communicated with a fluid access port and has a cylinder chamber through which pressure fluid flows in. The slide table reciprocates along an axial direction of the cylinder body. The cylinder tool has a piston slidingly arranged along the cylinder chamber. The cylinder tool reciprocates the slide table under the displacement of the piston. The locking tool displaces at a direction vertical to a direction of the displaced slide table. The locking tool is installed in the end of the cylinder body to control the reciprocation of the slide table.
