Power generation control device for hybrid vehicle

A power generation control device for a hybrid vehicle comprising a first electric motor that is mechanically coupled to a drive wheel and that is mainly used for travel driving, a second electric motor that is mechanically coupled to an internal combustion engine, and a battery that is electrically coupled to the first electric motor and the second electric motor, the power generation control device comprising:

• a power generation controller that carries out series power generation in which electric power is generated by the second electric motor by receiving driving force from the internal combustion engine while traveling by using the first electric motor as a drive source, and that carries out idle power generation in which electric power is generated by at least one of the first electric motor and the second electric motor by receiving driving force from the internal combustion engine while the vehicle is stopped, and
• the power generation controller sets a series power generation start threshold of a charge capacity of the battery at which the series power generation is started and an idle power generation start threshold of the charge capacity of the battery at which the idle power generation is started to the same value, and the same value is a value that maintains the charge capacity of the battery within a range in which it is not necessary to limit the output of the first electric motor during traveling.
