VEHICLE AND VEHICLE CONTROL METHOD

摘要

A vehicle includes an engine, a first MG (motor generator), a second MG, a planetary-gear-type motive power split device coupling them together, and an ECU (200) including an imbalance determination unit (210) and a pressing control unit (220). The imbalance determination unit (210) temporarily determines whether or not an imbalance abnormality has occurred based on an air-fuel ratio A/F, and when it is temporarily determined that the imbalance abnormality is present, controls the engine such that the engine is in an idle state and formally determines whether or not the imbalance abnormality has occurred based on fluctuations in engine rotation speed Ne. During a stop at idle, the pressing control unit (220) determines whether or not the formal determination process of the imbalance determination is ongoing and carries out pressing control to cause the first MG to generate pressing torque Tp when the formal determination process is not ongoing and does not carry out the pressing control so as not to cause the first MG to generate pressing torque Tp when the formal determination process is ongoing.
