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： An electronic control apparatus 100A is configured in such a way that a CPU 110A reads the conduction current of an opening/closing device 140n in an IPM 190A, by way of serial-parallel converters 114a and 114b and a second multi-channel A/D converter 116b; the opening/closing device 140n is opening/closing-controlled through a serial control signal SRn or a parallel control signal PWMn; and a reading timing control circuit 170n adjusts the reading timing in such a way that, regardless of the kind of the control signal, reading is performed during the period in which the opening/closing device 140n is driven to be closed. As a result, the serial-parallel converter can reduce the number of wiring leads between the IPM and the microprocessor, and the digital conversion value is accurately read, by adjusting the error between the serial-signal timing and the parallel-signal timing.

摘要： Even when, due to an abnormal decrease in the battery voltage, an engine control apparatus is inoperative, an engine can safely be started. Based on gearshift lever selection position information generated by a gearshift sensor (109A), a first detection circuit (194) generates a first detection signal PS1 when the gearshift lever is in the neutral position or in the parking position; a microprocessor (110A) is provided with a second detection means that generated a second detection signal PS2 when the gearshift lever is in the neutral position or in the parking position. Even when, due to an abnormal decrease in the voltage of a vehicle battery, the microprocessor (110A) is inoperative, by ascertaining through the first detection signal PS1 that the vehicle is in a state of not being driven, the engine can be started by means of a starting switch.

摘要： Respective positive terminal electric potentials of exhaust gas sensors are sequentially selectively inputted to an analog input terminal of a multi-channel AD converter through a multiplexer. An offset voltage is applied to respective negative terminals of the exhaust gas sensors. This offset voltage is inputted to another input terminal of the multi-channel AD converter. A microprocessor detects a generating voltage of the exhaust gas sensors by the difference between a digital converting value of the positive terminal electric potential and a digital converting value of the negative terminal electric potential. The microprocessor also individually judges that each of the digital converting values is excessively small and excessively large. Thus, the microprocessor judges the existence of ground, sky short circuit and disconnection abnormalities of the negative terminal and the positive terminal.
