    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.

    摘要: A first control circuit section (master station) and a second control circuit section (substation) communicate with each other via series-parallel converters. The master station includes regular transmission device and transmission-permitting signal generation device; and the sub station includes regular report device, confirmation reply device relative to a transmission data from the master station, and an unprocessed data table. The unprocessed data table prevents jam-up in upstream communication from the sub station to the master station, enabling to carry out timely regular transmission and regular reporting. Transmission from the sub station to the master station is performed based on a transmission-permitting control signal that the master station generates. Consequently, it is possible to execute communication error processing and diminish communication control burden on the master station while properly performing the regular transmission and regular report between the master station and sub station.

    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-subtracter. 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: A first control circuit portion carries out input/output control in cooperation with a microprocessor, a program memory, and a RAM memory. A second control circuit portion is in cooperation with the communication control circuit portion and the data memory to carry out serial communication with the first control circuit portion. A switch signal input to the second control circuit portion is stored in a first report packet, a digital conversion value for an analog signal input is stored in a second report packet, and the first and second packets are alternately periodically transmitted to the first control circuit portion. A multi-channel AD converter included in an analog signal input circuit starts to carry out AD conversion a prescribed time period after a first report packet is transmitted and finishes conversion before a second report packet is transmitted, so that up-to-date AD conversion data is transmitted.

    摘要: In an electronic control unit, a control constant stored in a program memory is transmitted to a data memory via a serial communication circuit. First control circuit section (master station) and second control circuit section (substation) mutually communicate through series-parallel converters. The master station includes regular transmission device and storage constant confirmation processing device. The substation includes regular report device and confirmation reply device to a data transmitted from the master station. A constant set data transmitted from the master station by regular transmission device is stored in the data memory at the time of normal receiving. Confirmation information such as sum value of the entire data in the data memory is reported by regular report device. At the master station, if there is any error in the confirmation information, a constant set data is retransmitted with regular transmission device. Reliability of data in the data memory is improved.
