Control device, hybrid vehicle, control method, and program

摘要

An electric motor can assist an engine at high conversion efficiency. A lower limit is set for the torque shared with an engine (10) by the electric motor (13) when the engine (10) and the electric motor (13) are operated together for traveling, and a hybrid ECU (18) has an assistance control unit that implements control to a traveling mode in which the engine (10) and the electric motor (13) operate together, only when it is estimated that the torque shared with the engine (10) by the electric motor (13) is equal to or greater than the torque lower limit when the electric motor (13) and the engine (10) are operated together for traveling.
