Zusammenfassung:	PURPOSE:To provide a cruise control device which can examine the cause of abnormality surely, even in the case of the generation of an electric power supply instant cut during the generation of an abnormality of 100% duty ratio. CONSTITUTION:A cruise control device is composed of such two CPU system as a main computer 11 for carrying out control and a sub-computer 12 for carrying out monitoring. The positive direction voltage and the drive electric power supply voltage of a motor 15 for driving a throttle valve are inputted in the sub-computer so as to be used for examination. A positive direction normal signal which is changed by the duty ratio same as that of the positive direction voltage from the sub-computer to the main computer is sent through a transmission line 17. When any instant cut is detected during the detection of the abnormality of 100% duty ratio in the positive direction voltage by the sub-computer, the positive direction normal signal is held at a high level and the detection of abnormality by the sub-computer is informed to the main computer, while maintaining the abnormality detection function of 100% duty ratio on the sub-computer side.
