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.

Apparatus and method for controlling oxygen sensor

A method for restart when Start-Stop Coasting (SSC) is released may include: determining whether a traveling vehicle satisfies a condition for releasing SSC after entry into SSC (S); determining whether emergency startup of the vehicle is required (S) when the traveling vehicle satisfies the condition for releasing SSC after entry into SSC; and performing a first startup process (S) in which a clutch () is engaged along with an operation of a starter motor () when the emergency startup of the vehicle is required.

Method and apparatus for restart when SSC is released

A SSC control method includes a condition satisfaction determination step of determining whether a vehicle can coast and a navigation information acquisition step of obtaining forward road information regarding a road section ahead of a current vehicle position when it is determined, in the condition satisfaction determination step, that the vehicle can coast. The method further includes a forward quick turn section determination step of determining whether a quick turn section exists in the road section ahead by using the forward road information obtained in the navigation information acquisition step, and an SSC entry step of controlling the vehicle to coast when it is determined in the forward quick turn section determination step that the quick turn section does not exist in the road section ahead.
