Vehicle and method of controlling vehicle

摘要

A vehicle includes an engine, a power storage device, a motor generator using electric power from the power storage device for generating driving force, and an ECU. The vehicle is capable of running with the operation mode selectively switched between the CS mode in which the vehicle runs utilizing the driving force from the engine and the motor generator, and the CD mode in which the vehicle runs preferentially utilizing the driving force from the motor generator in the state where the engine is stopped. When the OBD is performed for detecting a malfunction in the engine in the state where the CD mode is selected, the ECU keeps the operation mode being temporarily switched from the CD mode to the CS mode until the OBD is completed.

主权项

1. A vehicle comprising:
an internal combustion engine; a power storage device configured to store electric power; a rotating electric machine configured to generate a driving force using the electric power from said power storage device; and a control device configured to detect a malfunction in said internal combustion engine, said vehicle having, as an operation mode: a CS (Charge Sustaining) mode and a CD (Charge Depleting) mode, said vehicle being configured to run with said operation mode selectively switched between the CS mode and the CD mode, each of said CS mode and CD mode having a state where said internal combustion engine is operated and a state where said internal combustion engine is not operated, and in response to: (i) detecting a malfunction in said internal combustion engine during past operation of the vehicle, and (ii) said operation mode being said CD mode during present operation of the vehicle, said control device switches said operation mode to said CS mode and performs a malfunction detection process when said internal combustion engine is operated.
