Kind Code:
A1
Abstract:
A variable valve system (10) equipped with: a crank angle sensor (240) for measuring the angle of rotation of a crankshaft (200); a cam angle sensor (340) for measuring the angle of rotation of a camshaft (300) that operates in association with the crankshaft (200) and opens/closes a valve; and a control unit (100) for performing a start-time control of an internal combustion engine. The cam angle sensor (340) is configured as an absolute angle sensor for measuring the absolute angle of rotation of the camshaft (300). The control unit (100) begins the start-time control on the basis of the angle of rotation of the camshaft (300) measured by the cam angle sensor (340).
