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： An engine control system provides a gas concentration detection output irrespective of variation in product or change due to passage of time using an on-vehicle exhaust gas sensor. An exhaust gas sensor 107 and an electric heater 119 are connected to a microprocessor 120a, and an oxygen-concentration detection output Ip of exhaust gas, a calibration signal Vc and an internal resistance detection signal Vr are inputted through A/D converter 125. A program memory 121a stores standard characteristic data of the exhaust gas sensor 107. An atmospheric air oxygen-concentration detection output Ip0 under fuel-cut drive is measured and monitored. The electric heater 119 controls temperature so that the output coincides with the stored value. Current internal resistance of the exhaust gas sensor 107 is read and stored as target resistance. In normal driving, the electric heater 119 is controlled so that the internal resistance becomes the target resistance.

摘要： The invention improves safety of an electronic controller using a nonvolatile memory MRAM able to easily perform reading and writing operations at high speed. Therefore, MRAM for writing a control program from an external tool has a correction code adding writing circuit, a decoding reading-out circuit, and error registers for writing an error generating address number thereto as error data. When the error generating address is designated and confirmation reading-out is performed and an error is generated as before, an overlapping abnormality judgment is made and abnormality notification is performed. A program memory area of MRAM is normally in a writing inhibition state. When the external tool is connected, the inhibition state is released. The error registers are arranged in a data memory area set to no writing inhibition object.

摘要： In an on-vehicle electronic control unit, error in output voltages from a constant voltage power supply circuit (C.V.P.S.) for use in a reference power supply of an A/D converter, occurs due to temperature rise. Whereby, there is a problem of the decrease of an A/D conversion accuracy. A C.V.P.S. supplies a voltage to analog sensors and to an AD converter. Furthermore, an output from a temperature sensor that is disposed in the neighborhood of the C.V.P.S. is stored in a memory as a contrast temperature data T at a time point of shipping. In addition, voltage fluctuation characteristic data due to the change of temperatures of the C.V.P.S. and detection fluctuation characteristic data accompanied by the change of voltages of the analog sensor group have preliminarily been stored, and the fluctuations in digital converted values accompanied with the change of temperatures in the neighborhood of the C.V.P.S. are compensated.

摘要： A vehicular electronic control apparatus is provided with a program memory, a data memory, a RAM, a microprocesser, a reference data storage memory, a data memory abnormality judging section, and at least two transfer sections for a RAM. The reference data storage memory stores reference data corresponding to variable control data stored in the data memory. The data memory abnormality judging section judges whether the variable control data stored in the data memory are normal or abnormal. The first transfer section transfers and writes the variable control data from the data memory to the RAM. The second transfer section writes estimated variable control data based on the reference data from the reference data storage memory to the RAM.
