    摘要: A vehicle-mounted electronic control apparatus can perform a variety of abnormality detections while reducing the control load of a microprocessor in the abnormality detection of a volatile backup memory that is backed up by an on-board battery. The apparatus includes a control CPU which is fed with power from a main power supply circuit upon closure of a power switch, a nonvolatile control memory and a backup memory. Even if the power switch is opened, the backup memory, being a partial area of a RAM memory, is fed with power through an auxiliary power supply circuit connected directly to the battery. When the battery is replaced with a new one and connected again, a power supply interruption monitoring memory is reset. At the start of operation of the control CPU, the backup memory is initialized based on reset information, and the power supply interruption monitoring memory is rewritten into a set state.

    摘要: Provided is an on-vehicle electronic control device with low cost and low power consumption for performing monitoring control in both a driving mode and a parking mode of a vehicle. A main CPU is supplied with electric power from an on-vehicle battery via a power switching element and a main power supply circuit so as to control a plurality of electric loads in accordance with operating states of a plurality of input sensors. A sub CPU connected to the main CPU via a serial interface is supplied with electric power from the on-vehicle battery via a sub power supply circuit so as to monitor operations of the main CPU and input signals. The sub CPU has low speed and small memory capacity so as to operate with lower power consumption compared with the main CPU.

    摘要: A standard characteristic which is an average characteristic of multiple samples is approximated in a polygonal-line fashion by first to third lines. The coordinate-point positions of the first and second lines at comparison adjustment points are stored as standard data in a data memory of an electronic control apparatus. An actual-product characteristic as a calibration target is approximated in a polygonal-line fashion by first to third lines. The resistance value of a label resistor is adjusted to a value corresponding to ratios of monitoring outputs. The electronic control apparatus reads the resistance values of one or two label resistors, combines them with the stored standard characteristic, and interpolates a third line portion, thereby restoring and generating the actual-product characteristic.

    摘要: A standard characteristic which is an average characteristic of multiple samples is approximated in a polygonal-line fashion by first to third lines 315a, 325a, and 335a. The coordinate-point positions of the first and second lines at comparison adjustment points are stored as standard data in a data memory of an electronic control apparatus. An actual-product characteristic as a calibration target is approximated in a polygonal-line fashion by first to third lines 315b, 325b, and 335b. The resistance value of a first label resistor is adjusted to a value corresponding to ratios (V10n/V10, V20n/V20) of monitoring outputs. The resistance value of a second label resistor is adjusted to a value corresponding to ratios (V30n/V30, V40n/V40) of monitoring outputs. The electronic control apparatus reads the resistance values of the label resistors, combines them with the stored standard characteristic, and interpolates a third line portion, thereby restoring and generating the actual-product characteristic.
