HYBRID VEHICLE CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a hybrid vehicle control device capable of increasing a regeneration energy recovery amount during deceleration, while improving acceleration performance.SOLUTION: A hybrid vehicle control device is applied to a hybrid vehicle including: a power division mechanism including a planetary gear mechanism in which a first MG is connected to a sun gear, an engine is connected to a carrier, and an output part is connected to a ring gear; a second MG capable of outputting power to the output part; and a variable-inertia flywheel disposed on an output shaft of the engine. The hybrid vehicle control device executes acceleration control for: outputting power to a drive wheel from the second MG when acceleration of the vehicle is requested (S12); performing switching the variable-inertia flywheel to a low-inertia state (S15) until torque output from the second MG reaches switchover torque (S14) when acceleration is being requested (S12); and switching the variable-inertia flywheel to a high-inertia state (S17) after the torque output from the second MG reaches the switchover torque (S14).
