1. A control apparatus for a hybrid vehicle, the hybrid vehicle including
a power split mechanism, an engine, a first motor coupled to the engine via the power split mechanism, a second motor coupled to an output element of the power split mechanism, an electrical storage device connected to the first motor and the second motor, an engagement mechanism configured to prevent reverse rotation of the engine, and auxiliaries, the hybrid vehicle being configured to travel in electric traveling mode by using driving force that is output from the first motor and the second motor in a state where reverse rotation of the engine is prevented by the engagement mechanism, the control apparatus comprising: a controller configured to
i) start the engine in a state where the hybrid vehicle is traveling in the electric traveling mode,ii) obtain a first power, a second power, a third power, and a fourth power, the first power being a power that is required to start the engine, the second power being a required power based on acceleration and deceleration operation performed by a driver of the hybrid vehicle, the third power being a power that is consumed by the auxiliaries, and the fourth power being a power that is outputtable from the electrical storage device,iii) obtain a first correction value such that the first correction value becomes a smaller value as the fourth power increases, the first correction value becomes a larger value as the fourth power decreases, and the first correction value is a positive value or a negative value,iv) obtain a first threshold by subtracting the first power, the third power and the first correction value from the fourth power such that the first threshold becomes a larger value as the fourth power increases, andv) when the second power exceeds the first threshold while the hybrid vehicle is traveling in the electric traveling mode, start the engine. |
