Title: Abnormality diagnostic device for air-fuel ratio sensor
Inventor: YAMASHITA YUKIHIRO
IPC: G01N27/26
Filed: 1995-03-31
Abstract: PURPOSE: To diagnose the abnormality of an air-fuel ratio sensor and improve the control accuracy of an air-fuel ratio control system using the detected result of the air-fuel ratio. CONSTITUTION: Fuel injection valves 7 for injection-feeding fuel to each cylinder are disposed at the intake pipe of an internal combustion engine 1, and an A/F sensor 26 for linearly increasing/decreasing output to an air-fuel ratio is disposed at an exhaust pipe 12. A CPU 42 in an ECU 41 computes an air-fuel ratio correction factor on the basis of the deviation between the air-fuel ratio detected by the A/F sensor 26 and a target air-fuel ratio and executes air-fuel ratio feedback control using the correction factor. The CPU 42 judges whether to command the correction of the fuel injection quantity according to whether the target air-fuel ratio has changed exceeding the specified quantity (whether the target air-fuel ratio has suddenly changed).  At the sudden change time of the air-fuel ratio, the CPU 42 diagnoses the abnormality of the A/F sensor 26 from the result of comparing the variation of the air-fuel ratio correction factor with the variation of the target air-fuel ratio.

Abstract: PURPOSE:To obtain a stable picture, by improving the phase detecting sensitivity of an AFC circuit and quickening the pull-in to the AFC circuit and the phase controlling afterwards, if the synchronism is failed. CONSTITUTION:Assuming an output control current of an AFC circuit 2 generated with a synchronizing signal VSYC applied to a synchronizing signal applied terminal 1 and a comparison voltage Vc obtained from a flyback transformer 6 via an integration circuit to Is and a noise component to IN, then an AVC voltage VAFC is obtained at an output terminal 17. When a capacitance C1 of a capacitor 13 connected to the terminal 17 is sufficient greater than a capacitance C2 of a capacitor 14, the voltage VAFC is expressed in Equation 1. In case out of synchronism, a potential at a synchronizing detecting terminal 8 is increased, a switching transistor 16 turns on and both ends of a resistor 12 is shortened with the collector and emitter, then the voltage VAFC is expressed in Equation 2. Thus, in case out of synchronism, the voltage is made (n) times and the speed of the phase control is quickened.
