摘要： PROBLEM TO BE SOLVED: To provide an electronic controller capable of processing communication abnormality while properly performing regular transmission and a regular report between a master station and a slave station and capable of reducing a communication control load of the master station. SOLUTION: A first control circuit part 200a (master station) and a second control circuit 200b (slave station) communicate with each other via serial parallel converters 117 and 127. The master station 200a is provided with a regular transmission means 201a and a transmission permission control signal generation means 207a. The slave station 200b is provided with a regular report means 206a, a confirmation return means 201c to the transmission data from the master station 200a, and an untreated data table 203b. Since congestion of upload communication from the slave station 200b to the master station 200a is prevented by the untreated data table 203b, regular transmission and regular reporting can be carried out in a proper time, and transmission from the slave station 200b to the master station 200a is carried out based on the transmission permission control signal generation means 207a generated by the master station 200a.

A state whether or not downlink communication from the master station to the slave station is normal is confirmed by the confirmation reply means 205 and report reply means 215. When there are abnormalities in the periodic report date by the uplink communication, it can be confirmed by requiring resending/reading by the irregular transmission means 211. Congestion in the uplink communication from the slave station to the master station is avoided by the unprocessed date table 204, therefore, the periodic communication and periodic report can be timely executed.

摘要： PROBLEM TO BE SOLVED: To provide an engine control system in which an exhaust-gas sensor is provided for controlling air-fuel ratio of a vehicle-mounted engine in order to obtain an output of gas-concentration detection without having influence of variations in the product and secular changes. SOLUTION: In the engine control system, the exhaust-gas sensor 107 and an electric heater 119 are connected to a microprocessor 120a. In the microprocessor 120a, a detection output Ip of oxygen-concentration of the exhaust gas, a calibration signal Vc, and a detection output Vr of an internal resistance are input through A/D converter 125. In a program memory 121a, standard characteristic data on the exhaust-gas sensor 107 are stored. Sensor temperature is controlled by the electric heater 119 in the following way. That is, atmospheric oxygen-concentration detection output Ip0 is monitored at a time of fuel-cut driving as in downslope driving, and the temperature is controlled by the electric heater 119 so as to make the output Ip0 agree with the above stored value. The internal resistance of the gas sensor 107 at that time is read and stored as a target resistance. Further, in normal operations, the heater 119 is controlled so as to make the internal resistance of the gas sensor 107 agree with the above target resistance. COPYRIGHT: (C)2005,JPO&NCIPI
