1. A method for controlling a variable valve lift apparatus, comprising:
measuring an operation mode switching condition of the variable valve lift apparatus; determining, by a controller, whether the variable valve lift apparatus is in a normal operation condition based on the measured operation mode switching condition; controlling, by the controller, operation of the variable valve lift apparatus based on a predetermined normal valve lift switching map if it is determined that the variable valve lift apparatus satisfies the normal operation condition; determining, by the controller, whether the variable valve lift apparatus is in a mode switching delay or switching disable condition from a high lift mode to a low lift mode or whether the variable valve lift apparatus is in the mode switching delay or switching disable condition from the low lift mode to the high lift mode, if it is determined that the variable valve lift apparatus does not satisfy the normal operation condition; controlling, by the controller, the operation of the variable valve lift apparatus based on a predetermined low oil temperature valve lift switching map when the variable valve lift apparatus is in the mode switching delay or switching disable condition from the high lift mode to the low lift mode; and controlling, by the controller, the operation of the variable valve lift apparatus depending on a predetermined high oil temperature valve lift switching map when the variable valve lift apparatus is in the mode switching delay or switching disable condition from the low lift mode to the high lift mode. |
