Abstract
A control device of a hybrid vehicle, the hybrid vehicle including an engine, a motor as a traveling power source, and a battery in which electric power to be supplied to the motor is charged, includes: a transient operation controller performing, when absolute values of an outputtable electric power and a chargeable electric power of the battery are small at a time of a transient operation of the engine, a transient operation of controlling an operating point of the engine within a wide range from low output to high output, at a position where a thermal efficiency is lower than the thermal efficiency at a time of a steady operation, and of controlling the engine to be in a combustion state where a margin to a combustion limit is greater than the margin in the steady operation.
