Abstract
An electronic control apparatusA is configured in such a way that a CPUA reads the conduction current of an opening/closing devicein an IPMA, by way of serial-parallel convertersandand a second multi-channel A/D converter; the opening/closing deviceis opening/closing-controlled through a serial control signal SRn or a parallel control signal PWMn; and a reading timing control circuitadjusts 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 deviceis 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.
