Until a vehicle system is activated, a switching circuit outputs a pilot signal to an OR circuit. As a result, lowering of the potential of the pilot signal caused by a resistance circuit is avoided, and the pilot signal is provided in a non-pulsed manner. A power supply CPU is activated in accordance with any one of a connector signal and the non-pulsed pilot signal. When the vehicle system is activated, the switching circuit switches an output destination of the pilot signal to the resistance circuit.

A drive circuit includes a gate voltage detector that detects a gate-emitter voltage Vge that appears between the gate and emitter of a power semiconductor device throughout a detection time period during which a sampler allows the process of detecting the gate-emitter voltage Vge, and that recognizes the occurrence of an abnormality in the power semiconductor device when the gate-emitter voltage Vge exceeds a reference value. Therefore, the drive circuit can protect the power semiconductor device with higher reliability by promptly detecting the occurrence of a short circuit even when the power semiconductor device is resistant to high voltages.

An internal pressure explosion-proof system is provided that is capable of detecting high-pressure abnormality of an internal pressure explosion-proof mechanism, urging a check of gas/air apparatus by providing a means for notifying a user of abnormality, and decreasing excessive pressure of an internal pressure chamber. A high-pressure abnormality detector and a pressure regulating valve are provided in an air discharging portion for releasing the gas/air discharged from the internal pressure explosion-proof mechanism. The working pressure of the high-pressure abnormality detector is set to be lower than the working pressure of the pressure regulating valve. The high-pressure abnormality detector sends a signal when the pressure becomes higher than the set pressure to make the alarm give a warning and makes the open valves open to decrease the pressure of the internal pressure chamber of the internal pressure explosion-proof mechanism which became excessive.

When the driving wind and the cooling wind are generated, based on the phenomenon in which the temperature difference is generated between the front surface and the rear surface of the radiator (14), the temperature difference between the detection value of the rear temperature sensor (22) and the detection value of the front temperature sensor (21) is compared with the abnormality determination value so that it is determined whether the front temperature sensor (21) and the rear temperature sensor (22) are properly fixed on the radiator (14), whereby it is determined whether the abnormality (unauthorized alteration) exists. By setting the abnormality determination value according to the ambient temperature and the vehicle speed, corresponding to a variation in temperature difference between the front surface and the rear surface of the radiator (14), the abnormality determination value is varied to be set at a proper value.

In an idle stop vehicle, a starter has separately an electromagnetic switch for energizing a motor and a pinion control solenoid for engaging a pinion gear with a ring gear. A coil of the solenoid is energized by a battery through a relay. For starting an engine, an ECU turns on the relay and the electromagnetic switch so that the starter cranks an engine. During engine operation, the ECU turns on only the relay while maintaining turn-off of the electromagnetic switch. If a voltage of a current supply path between the relay and the coil is lower than a predetermined threshold value, the ECU prohibits automatic idle stop by determining that the current supply path to the coil has abnormality.
