摘要：
Upon satisfaction of the condition for making the malfunction diagnosis at least one of the EGR system, the air-fuel ratio sensor 135a and the oxygen sensor 135b during the fuel cut of the engine 22, a fuel cut of the engine 22 and performing the mortaring of the engine 22 by means of the motor MG1 are continued until the completion of the malfunction diagnoses of all objects, of which the each condition for making the malfunction diagnosis is satisfied among the EGR system, the air-fuel ratio sensor 135a and the oxygen sensor 135b. This arrangement ensures the occasions for making the malfunction diagnoses of the EGR system, the air-fuel ratio sensor 135a and the oxygen sensor 135b.
摘要（中）：
在满足在发动机22的燃料切断期间对EGR系统，空燃比传感器135a和氧传感器135b中的至少一个进行故障诊断的条件，发动机22的燃料切断并执行 通过电动机MG1继续发动机22直到完成对EGR系统，空燃比传感器135a和氧气之间满足故障诊断的每个条件的所有物体的故障诊断 传感器135b。 这种布置确保了对EGR系统，空燃比传感器135a和氧传感器135b进行故障诊断的场合。
