Abstract:
A hybrid vehicle in which a running mode can be appropriately shifted without making a driver feel uncomfortable or feel a sense of slowness. A hybrid vehicle includes an engine, a first motor, a second motor, and a clutch that selectively transmits power between the engine and drive wheels. A controller shifts a running mode to the parallel hybrid vehicle mode in a case of accelerating the hybrid vehicle in the electric vehicle mode, if the drive force is greater than a maximum drive force generatable in the electric vehicle mode, and also greater than a required additional drive force as a variable corresponding to a running resistance against the hybrid vehicle running on a predetermined running road at a predetermined vehicle speed by a predetermined drive force that is set in advance based on the vehicle speed and the drive force.
