This exercise is referred to by several names. Names include, Ab Crunches with Knee Raises, Ab Crunch with Reverse Crunch, V-Sit-Ups etc. It's also common to increase the work placed on the Oblique muscles by touching opposing knee and elbow at the mid-point of the action.
Performed with good-form (slow & controlled), this is one of my favored Ab exercises. If you get "good" at this exercise, rather than increase repititions beyond 20, increase difficulty by pausing at the mid-point of the movement, or include as one of your exercises within a Superset, Tri-Set or Giant-Set.
