Control device and control method for a hybrid vehicle

A control method for a hybrid vehicle, which is to be carried out by a control device for a hybrid vehicle comprising:

• a mechanical power source;
• an electric motor to be used when the mechanical power source is started;
• a first clutch arranged between the mechanical power source and a first transmission mechanism including a plurality of gear shift stages, for transmitting power of the mechanical power source to the first transmission mechanism or shutting off the transmission;
• a second clutch arranged between the mechanical power source and a second transmission mechanism including a plurality of gear shift stages, for transmitting the power of the mechanical power source to the second transmission mechanism or shutting off the transmission;
• and
• an electrical power source coupled to an input shaft of the first transmission mechanism, and capable of carrying out regenerative driving,
• the control method comprising:
• determining whether or not a gear shift request for shifting the gear shift stage of the first transmission mechanism is made during a regeneration travel of the electrical power source;
• and
• controlling a torque of at least one of the second clutch or the electric motor so as to compensate a braking force decreased upon a gear shift in the electrical power source when the gear shift request is made,
• wherein, during the regeneration travel of the electrical power source, based on the determining, compensating for the torque of the second clutch and the torque of the electric motor or for the torque of the electric motor only.
