PROBLEM TO BE SOLVED: To inhibit degradation in detection accuracy of the rotational position of a camshaft in a vehicle in which an engine, a drive motor, and a power generation motor are connected via a planetary gear mechanism even if a crankshaft of the engine rotates despite control over the rotation state of the power generation motor such that the engine does not rotate when the vehicle is driven only by the drive motor.SOLUTION: A rotational position of a camshaft at a time when an engine 1 stops is stored. When a drive motor 6 operates while the engine 1 stops, an angle change by as much as the number of pulses of a crankshaft sensor relative to the stored rotational position is integrated, thereby calculating the rotational position of the camshaft. It is thereby possible to prevent erroneous calculation of the rotational position of the camshaft due to erroneous recognition of a reference pulse signal in a crank signal. |
