摘要： An on-vehicle electronic control device 100A serially transmits A/D conversion data of plural channels from a second control circuit unit 300A including a multichannel A/D converter 204A to a microprocessor 110A disposed in a first control circuit unit 200A. The A/D conversion data are organized into a communication packet and transmitted via first and second buffer memories 204b and 204d, and when there is an abnormality in the A/D conversion data, transfer between the first and second buffer memories 204b and 204d is prohibited and an abnormality report is performed with respect to the microprocessor 110A. As a result, erroneous data are not transmitted, and communication congestion and the burden of the microprocessor 110A are alleviated.

摘要： First and second control circuit sections that mutually communicate via a series-parallel converter comprise first and second adder-subtracter respectively. When any receiving error occurs in each control circuit section, a variation value 3 is added to the adder-subtracter on the receiving side. When data is normally received, a variation value 1 is subtracted from the adder-subtradcter. Initial value of the adder-subtracter is set to 9. When a current value exceeds 11, first and second error detection signal is generated to carry out alarm display or initialization, and initialization and restart of the other-side control circuit section.

摘要： An electronic control apparatus is provided in which a supervisory control circuit part capable of mutual communication with a main control circuit part, which is operated by a high speed clock signal of high precision, is operated by a medium speed clock signal, which is low in cost and precision, such that they can operate mutually independently of each other. The main control circuit part supplies a medium speed communication synchronization signal frequency divided to the supervisory control circuit part. The supervisory control circuit part is operated by the medium speed clock signal to supervise the control operation of the main control circuit part. An error measuring circuit calculates an error correction coefficient which is the ratio of the signal cycle of the communication synchronization signal to that of the medium speed clock signal. The value of the error correction coefficient is reversely supervised by the main control circuit part.
