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： 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.
