The hosts took the lead in the 10th minute on a goal by Guido Burgstaller at the end of counter launched by Amine Harit from in front of the Schalke net on Wednesday, reports Efe.
Schalke had a chance to double their lead five minutes later, but Wolfsburg goalkeeper Koen Casteels turned aside a strike by Marko Pjaca.
The visitors threatened twice in quick succession about midway through the first half.
On the first occasion, Schalke keeper Ralf F?hrmann sent Maximilian Arnold's free kick for a corner, which set up an effort by Yunus Malli that bounced off the cross-bar.
The only highlight of a mostly quiet second half came in the 84th minute, when a Wolfsburg free kick led to a header that forced Schalke midfielder Leon Goretzka to make a timely goal-line clearance.
Schalke join Bayern Munich, Bayer Leverkusen and Eintracht Frankfurt in the semifinals.
