Title: Air-fuel ratio control device for internal combustion engine
Inventor: YOSHIMURA TAKAYUKI
IPC: F02D41/14
Filed: 1987-10-01
Abstract: PURPOSE:To prevent a control constant from being excessively compensated, by setting the updating speed of the control constant to a small value when an averaged output from an upstream sensor is shifted in such a case that the air-fuel ratio is controlled in accordance with air-fuel ratio sensors which are arranged respectively upstream and downstream of a ternary catalyst disposed in an exhaust passage. CONSTITUTION:An estimating means A estimates an averaged air-fuel ratio from an output from an air-fuel ratio sensor (a) upstream of a ternary catalyst. If the averaged air-fuel ratio becomes less than a first predetermined value when the output of a downstream air-fuel ratio sensor (b) indicates a rich air-fuel ratio, or if the averaged air-fuel ratio exceeds a second predetermined value when the output of the downstream side sensor (b) indicates a lean air-fuel ratio, an updating speed computing means B decreases the updating speed of a control constant. Further, a control constant computing means C computes an air-fuel ratio feed-back control constant from the above-mentioned updating speed on the basis of the output of the downstream sensor (b), and computes an air-fuel ratio compensating value from the control constant and the output of the upstream sensor (a).

IPC: G01B7/00
Filed: 1984-11-22
Abstract: PURPOSE:To detect information from a potentiometer with a high accuracy even if the fluctuation of an electric power source voltage is obtained by detecting and comparing the electric power source voltage applied to the potentiometer at every measurement. CONSTITUTION:A control and processing circuit 89 operates a switch 74 and an analog/digital converter 84 through a control bus line 93, stores values of VX1-VX3 and VY1-VY3 and calculates equation I. If AX+BX=1 and AY+BY=1 are not established, the circuit 89 measures data again. When the data equals '1', the AX and the AY are stored as data on a position where a joy stick stands still. Then the circuit 89 measures continuously the voltage of each terminal to calculate the AX and the AY, and iterates the comparison of them with the value stored initially as the joy stick still position data. If some value changes, with the newly calculated AX and AY as the position data, a new cross mark at the position on a screen corresponding to the position data is displayed, and an operation returns the iteration of the comparison of the AX and AY.
