摘要： A resin-sealed electronic controller obtained by bonding and fixing a circuit board to a thermally-conductive base plate, and integrating circuit components with a molding resin so as to reduce the size. A base plate includes a first exposed portion, a second exposed portion, and an adjacent flat portion adjacent to a central window hole. First circuit components which are low-heat-generating components with large height are located in the central window hole. Second circuit components which are high-heat-generating components with small height are provided on an area corresponding to the adjacent flat portion. A height dimension of the first circuit components at least partially overlaps a thickness dimension of the base plate, to reduce a total thickness dimension. The high-heat-generating components and the low-heat-generating components being provided separately from each other permits increased mounting density of low-heat-generating components, reducing an area of the circuit board.

摘要： A linear solenoid is configured with an electromagnetic coil and a label resistor that are integrated with each other; the label resistor has a resistance value corresponding to a correction coefficient based on the difference between the actual characteristic of the supply current vs. adjusted hydraulic pressure output of the electromagnetic coil and a standard characteristic; and data for correcting a characteristic variation in the command current vs. output current characteristic of an electromagnetic coil is preliminarily stored in a control module by use of an adjustment tool. When the operation is started, the resistance value of the label resistor is read and an output current corresponding to a utilized linear solenoid is supplied, so that a target adjusted hydraulic pressure is obtained.

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.
