ABSTRACT:
An engine rotational speed determining device is disclosed which includes a signal inputting means and a rotational speed determining means. The signal inputting means inputs a signal that indicates current supplied to an electric motor, which starts an internal combustion engine, during a starting operation of the engine by the motor. The rotational speed determining means determines a rotational speed of the engine in the starting operation based on a change in the current indicated by the signal input by the signal inputting means.
