Control apparatus and method for variable valve

摘要

A control apparatus controls an electromagnetically driven valve, which includes at least one of an electromagnetically driven exhaust valve for opening or closing an exhaust valve and an electromagnetically driven intake valve for opening or closing an intake valve in an internal combustion engine. The control apparatus is provided with: a first judging device for judging whether or not the electromagnetically driven valve fails in seating for valve-opening; and a fail-safe device for controlling the electromagnetically driven valve to perform an operation of valve-opening again in a same stroke if it is judged by the first judging device that the electromagnetically driven valve fails in the seating for valve-opening.
