Abstract

An apparatus for controlling an oxygen sensor may include an oxygen sensor configured to measure the exhaust gas which is generated by the combustion of the engine to generate an oxygen signal, and a controller configured to detect, through the oxygen sensor, a lag of the oxygen signal having responsiveness which is reduced depending on an oxygen amount of the exhaust gas, store information on occurrence factors which cause the lag of the oxygen signal, and increase a current heating quantity of a corresponding specific region about the occurrence factors to reconfirm whether the oxygen signal lags and determine the oxygen sensor as a failure or release a failure detection for the oxygen sensor.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2014-0148131 filed on October 29, 2014, the entire contents of which are incorporated herein by reference. technical field [0003] Various aspects of the present invention relate to an oxygen sensor, and more particularly, the present invention relates to an apparatus and method for controlling an oxygen sensor capable of performing diagnosis for detecting a failure of the oxygen sensor. Background technique [0004] In a typical engine-driven device, when the engine is started, the fuel pump sends the fuel in the fuel tank to the injector through the fuel pipe, and the engine control device drives the injector to inject fuel. The injected fuel is combusted, after which the exhaust is expelled. [0005] An example of a device for measuring exhaust gas oxygen concentration may include an oxygen sensor. The oxygen sensor is installed at a predeterm...
