Title:
ハイブリッド車両における空燃比センサの学習装置
Document Type and Number:
Japanese Patent JP5774530
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a learning apparatus for an air-fuel ratio sensor in a hybrid vehicle capable of recovering deceleration energy as electric power through regenerative control of an electric motor and capable of appropriately and reliably executing learning processing for the air-fuel sensor as required.SOLUTION: When execution of learning processing for an air-fuel ratio sensor is requested and a vehicle is determined to be under deceleration (Yes in S2, 6), either one of clutches C1, C2 is connected and an engine is motored by drive from a driving wheel side (S14). An engine speed Ne rises higher than an idling speed and fuel cut of an engine is performed, thereby allowing learning processing for the air-fuel sensor to be executed.
