摘要： A valve timing control apparatus for an internal combustion engine can be improved in accuracy in the detection of valve timing (cam angles). A crank angle sensor generates a crank angle signal in the form of a train of pulses. Cam angle changing parts change phases of camshafts relative to a crankshaft. Cam angle sensors generate cam angle signals. A reference crank angle detection part detects reference crank angles based on the crank angle signal. Cam angle calculation parts calculate the cam angles of the camshafts based on the crank angle signal and the cam angle signals. A cam angle control part controls the relative phases of the camshafts to the crankshaft so as make them coincide with target cam angles corresponding to operating conditions of the engine. A cam angle calculation part calculates the cam angles by counting the number of pulses of the crank angle signal.
