摘要： The leakage resistance detection device includes a coupling capacitor having one terminal connected to an on-board high voltage device and another terminal connected to a repetitive signal output circuit, and measures a leakage resistance as a function of a transition time during which a monitoring voltage, which is a potential at the another terminal of the coupling capacitor to be charged/discharged in response to an operation of a charge/discharge switching element that operates in response to a repetitive pulse signal, changes from one predetermined voltage to reach another predetermined voltage. When the measured leakage resistance has become equal to or smaller than a predetermined limit leakage resistance, the leakage resistance detection device generates a resistance abnormality determination output.

摘要： Provided is a drive control device capable of surely detecting, by a monitoring/controlling unit, an abnormality of a short circuit and a disconnection in a power supply circuit to an electric load, and of decreasing a load required for a quick response imposed on the monitoring/controlling unit. A switching element is controlled to open/close by a control output signal generated by a monitoring/controlling unit, and a determination storing circuit determines whether circuit opening and circuit closing have been correctly carried out and stores a result of the determination, and periodically reports to the monitoring/controlling unit. While the stored content of the determination is periodically reset, the determination operation is updated and continues. The monitoring/controlling unit does not need to immediately monitor the determination storing signal when the open/closing command is generated.

摘要： An analog input signal obtained from an analog sensor group 104A and first and second calibration voltages obtained by high-precision voltage-dividing resistors are successively selected by a multiplexer, digitally converted through an AD converter and then input to a microprocessor. The microprocessor calculates a collinear approximate coefficient based on the first and second calibration voltages in cooperation with a program memory, and corrects the digital conversion value to the analog input signal by using the approximate coefficient, thereby correcting a linear error of the conversion characteristic of the AD converter. In the calculation of the approximate coefficient, upper and lower limit check is executed on measurement values and calculation coefficients, and also plural calculation results are averaged to enhance the precision.

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： A single state detector circuit can quickly detect short-circuit and open-circuit abnormalities of a load controlled by a power transistor. A DC power supply, the load and the power transistor are serially connected with one another, so that a switching terminal voltage of the power transistor is binarized into high and low levels by the state detector. The power transistor is linearly controlled by a constant-current control circuit so as to suppress an excessive current, and power supplied to the power transistor is interrupted by an overheat interruption circuit. Upon occurrence of a short-circuit in the load during generation of an energization command, a switching terminal voltage of the power transistor becomes stabilized at a high level without intermittent operation, which is detected by the state detector. Upon occurrence of an open-circuit during generation of a deenergization command, a low switching terminal voltage is detected by the state detector.

摘要： In a power supply system provided with an assembled battery supervisory device which supervises an assembled battery composed of storage elements connected in series with one another, the system using the assembled battery is obtained which makes it possible to supply electric power to the assembled battery supervisory device, with a simple arrangement. The arrangement is such that electric power for the assembled battery supervisory device is obtained from a part of storage elements constituting the assembled battery. The cell balancer is driven based on the average consumption electric current of the assembled battery supervisory device so as to suppress a deviation in the amount of charge between those storage elements which supply electric power to the assembled battery supervisory device, and those storage elements which do not supply electric power to the assembled battery supervisory device, resulting from the average consumption electric current of the assembled battery supervisory device.

摘要： A vehicle mounted engine control apparatus serves to prevent air fuel ratio control from becoming an excessively fuel rich state by sequentially actuating heaters for early activation of a pair of exhaust gas sensors arranged in an upstream and a downstream position of a catalyzer. Electric power is first supplied to a heater for an upstream exhaust gas sensor, and the supply of electric power to a heater for a downstream exhaust gas sensor is started without waiting for activation of the upstream exhaust gas sensor, if a heater current declines to a predetermined value or less. When the upstream exhaust gas sensor is inactive, an output signal of an upstream air fuel ratio control unit inputted to a fuel injection control unit is restricted to a predetermined fuel rich command, and when the downstream exhaust gas sensor is inactive, an output signal of an downstream air fuel ratio control unit inputted to the upstream air fuel ratio control unit is restricted to a predetermined fuel rich command.

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.
