Variable valve lift apparatus and control method for the same

The present invention relates to a method comprising: a variable valve lift control device, measuring the operation mode switching conditions of the variable valve lift device; Determining whether the controller on the basis of the measured operating mode change condition corresponds to the normal operating condition of the variable valve lift device; Further comprising: if any of the above normal operating conditions, wherein the controller according to the normal valve lift switching map previously set controlling the operation of the variable valve lift device; Does not satisfy the normal operating conditions, if the controller has the variable non-valve lift high lift mode switching delay or switching to the low lift mode, in the mode of the device condition or, in the low lift mode of the variable valve lift device to the high lift mode, mode, determining whether switching delay or non-conversion conditions; If not the variable valve lift in the high lift mode, the low lift mode, the mode switching delay, or switch to the device condition, and controlling the operation of the variable valve lift device in accordance with the low oil temperature map, the valve lift switch, the controller previously set; And controlling the operation of the variable valve lift device in accordance with the variable valve timing when the lift of the low lift mode, the high lift mode to the mode switching delay or switch not conditions in the apparatus, a pre-set unique on the valve lift switch, the controller maps; It includes.
