Abstract:
1. A control apparatus for a vehicle having a multi-cylinder engine including a crankshaft rotatably disposed therein and a camshaft rotatably disposed therein, comprising: a crankshaft position acquiring unit configured to acquire crankshaft position information representing a rotational position of the crankshaft at each predetermined angular interval in response to rotation of the crankshaft; a camshaft signal acquiring unit configured to acquire camshaft signals having different modes, which switch from one to another in association with cylinders of the engine that operate in successive combustion strokes, in response to rotation of the camshaft of the engine; and a correcting unit configured to correct the crankshaft position information acquired from the crankshaft position acquiring unit based on the camshaft signals acquired from the camshaft signal acquiring unit; wherein the correcting unit acquires from the crankshaft position acquiring unit stopped crankshaft position information, which is representative of crankshaft position information at a time that the engine stops operating; the correcting unit acquires from the crankshaft position acquiring unit switching crankshaft position information, which is representative of crankshaft position information at a time that the camshaft signals switch from one to another when the engine is started or restarted; and the correcting unit corrects the stopped crankshaft position information based on the acquired switching crankshaft position information.
