HYBRID VEHICLE HAVING ENGAGABLE CLUTCH ASSEMBLY COUPLED BETWEEN ENGINE AND TRACTION MOTOR

摘要

A hybrid vehicle includes a battery system (110), an internal combustion engine (104), a first motor/generator (106), a second motor/generator (108) and an engagable clutch assembly (206). The engagable clutch assembly (206) is disposed between the internal combustion engine (104) and the first motor/generator (106). When engaged, the engagable clutch assembly (206) couples the rotor spindle of the second motor/generator (108). The engagable clutch assembly (206) may also operate in a first mechanical mode that selectively engages and disengages the internal combustion engine (104) from the second motor/generator (108), or operate in a second mechanical mode that dampens shock between the internal combustion engine (104) and the first motor/generator (106) when the internal combustion engine (104) operates at a rotational speed that is different from a rotational of the first motor/ generator (106).
