Traveling mode switching controller of hybrid electric vehicle

A traveling mode switching controller of a hybrid electric vehicle (1) has a velocity detection unit, a state-of-charge detection unit (11a), and a switching control unit (20) for selectively switching among first to third traveling modes. In the first traveling mode, an engine (2) is deactivated an...

Beschreibung
Zusammenfassung:	A traveling mode switching controller of a hybrid electric vehicle (1) has a velocity detection unit, a state-of-charge detection unit (11a), and a switching control unit (20) for selectively switching among first to third traveling modes. In the first traveling mode, an engine (2) is deactivated and a drive motor (4, 6) is activated to actuate drive wheels (3, 5). In the second traveling mode, the engine (2) activates a generator (9) to activate the drive motor (4, 6). In the third traveling mode, the engine (2) activates the drive wheels (3, 5). When the state of charge is less than a first state of charge, the switching control unit (20) performs switching between the second traveling mode and the third traveling mode at a first velocity. When the state of charge is the first state of charge or more, the switching control unit (20) performs switching between the first traveling mode and the third traveling mode at a predetermined velocity higher than the first velocity.
