Abstract
An on-vehicle electronic control deviceA serially transmits A/D conversion data of plural channels from a second control circuit unitA including a multichannel A/D converterA to a microprocessorA disposed in a first control circuit unitA. The A/D conversion data are organized into a communication packet and transmitted via first and second buffer memoriesand, and when there is an abnormality in the A/D conversion data, transfer between the first and second buffer memoriesandis prohibited and an abnormality report is performed with respect to the microprocessorA. As a result, erroneous data are not transmitted, and communication congestion and the burden of the microprocessorA are alleviated.
