<P>PROBLEM TO BE SOLVED: To provide a valve control device of a camless structure engine capable of effectively enhancing the control accuracy to the target lift amount of a valve when the valve is opened. <P>SOLUTION: There is provided the valve control device 1 of the camless structure engine having a lift amount adjusting mechanism capable of adjusting the lift amount of a valve 10 according to the operating state of the engine when the valve 10 is opened. The valve control device 1 includes a lift amount detection means 31 for detecting the lift amount of the valve 10, operating state detection means 32, 33 for detecting the operating state, a target lift amount setting means 22 for setting the target lift amount of the valve 10, a mechanism control means 20 for controlling the lift amount adjusting mechanism so that the lift amount of the valve 10 may reach the target value, and a learning means 25 for learning the lift amount characteristic of the lift amount adjusting mechanism on the basis of the target lift amount and the actual lift amount. <P>COPYRIGHT: (C)2012,JPO&INPIT |
