Abstract
Piston to valve interference in an internal combustion engine is detected and alleviated by adjusting valve timing, valve lift, and/or compression ratio. Specifically, based on actuator motion, an actuator is selected to reduce potential interference. Further, potential sensor and hardware degradation are considered in controlling actuators to reduce potential interference.
