| titleOfInvention | Oxygen sensor interface circuit and oxygen sensor monitoring method using the same |
| abstract | The present invention provides for continuous disconnection and short-circuit monitoring of an oxygen sensor, and for disconnection and short-circuit monitoring of a low voltage output terminal connected to ground.n n n The present invention is connected in parallel to the high voltage output terminal of the oxygen sensor pull-up resistor for dividing the voltage of the detection signal, the filter unit for removing the noise contained in the signal passed through the pull-up resistor, the pumping current supply unit for supplying a pumping current to the oxygen sensor In addition, the low voltage output terminal and the microcomputer of the oxygen sensor is connected to a predetermined position and includes a pull-down resistor connected in parallel with one side is connected to the ground.n n n Accordingly, the present invention reads the high voltage output terminal voltage value and the low voltage output terminal voltage value of the oxygen sensor according to the ignition switch, and compares the read voltage value and the reference voltage value of each output terminal to the high voltage output terminal and the low voltage output. Judge the disconnection or short circuit of the terminal. |
