Abstract
A hybrid vehicle according to the present invention includes a control unit for, when regenerating a post-treatment device while the vehicle is stopped, performing a high-load operation of an engine by operating an electric motor as a generator by the engine. A memory of a hybrid ECU retains a power generation map in which are recorded the rotational speed of the engine and/or a power generating torque corresponding to the amount of particulate accumulation of the post-treatment device when regenerating the post-treatment device. The control unit constitutes a regeneration control device for determining, on the basis of the power generation map, the rotational speed and/or the power generating torque of the engine corresponding to the amount of particulate accumulation of the post-treatment device when the engine operates the electric motor as a generator while regenerating the post-treatment device of the stopping hybrid vehicle.
