Abstract: An internal combustion engine controlling apparatus controls an internal combustion engine of an automotive vehicle, and includes a sensor arranged to detect a state quantity concerning an automotive vehicle, and a signal abnormality detection device arranged to detect an abnormality in a state quantity signal which is output from the sensor. The signal abnormality detection device includes a calculation section arranged to receive a state quantity signal which is output from the sensor, and to calculate a second derivative of a state quantity represented by the state quantity signal, and an abnormality determination section arranged to determine whether the state quantity signal is abnormal or not based on the second derivative calculated by the calculation section.
