摘要： A motor drive control device is provided in which if any abnormality occurs in a drive control circuit, drive command signals the drive control circuit generates are interrupted at once, so that an AC motor can be stopped in safety. A monitor control circuit and drive command signal interruption circuit are provided to the drive control circuit that takes variable-speed control of the AC motor supplied with power from a DC drive power source via a semiconductor bridge circuit. If any abnormality occurs in the drive control circuit, the drive command signals the drive control circuit generates are interrupted at once. When starting operation, the drive control circuit and monitor control circuit cooperate with each other to conduct preliminary check as to whether or not the drive command signal interruption circuit operates normally, base on a predetermined time schedule, and stop the AC motor without fail if any abnormality occurs during operation.

摘要： In an internal-combustion-engine control apparatus provided with an exhaust gas sensor control device that outputs a detection signal detected by an exhaust-gas sensor, while switching amplification factors of an amplification circuit or offset voltages of an offset circuit, it is determined whether the exhaust-gas sensor is in an activation state or not, and an electric current flowing into the exhaust-gas sensor is stopped, in the case where it is determined that the exhaust-gas sensor is in a non-activation state; the amplification factors of the amplification circuit are switched so that there is detected an air-fuel ratio signal at the time when an electric current flowing into the exhaust-gas sensor is stopped, and it is determined whether or not the offset circuit is abnormal, based on whether the respective air-fuel ratio signals at the amplification factors are within a predetermined range.
