System and method for controlling variable valve time

摘要

The present disclosure provides a variable valve time control system and method. The variable valve time control system comprises an actuator, an actuation switch valve, an electronic control unit and a displacement sensor. The electronic control unit controls the actuation switch valve. The displacement sensor detects the engine valve displacement signal. The electronic control unit calculates the engine valve opening and closing times based on the displacement signal from the engine valve displacement sensor, and translates the engine valve opening and closing times into the corresponding switch times of the actuation-switch-valve power output.
