Title:
VEHICLE DRIVE SYSTEM AND METHOD FOR CONTROLLING VEHICLE DRIVE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/158604
Kind Code:
A1
Abstract:
Disclosed is a vehicle drive system (1) provided with first and second engines (ENG1, ENG2); first and second transmissions (TM1, TM2); first and second one-way clutches (OWC1, OWC2) respectively provided in output units of the first and second transmissions; a rotary-driven member (11) commonly coupled to output members (121) of the first and second one-way clutches (OWC1, OWC2) via clutch mechanisms (CL1, CL2); a main motor generator (MG1) connected to the rotary-driven member (11); and control means (5) for controlling components. When a vehicle moves backward, the control means (5) blocks the clutch mechanisms (CL1, CL2), and releases a condition that the backward movement of the vehicle is prevented by the transmissions (TM1, TM2), so that the reverse rotation of the main motor generator (MG1) moves the vehicle backward. When a vehicle starts climbing a hill, the connection of the clutch mechanisms (CL1, CL2) is maintained, and a hill-hold function is available using a backward movement prevention action caused by the transmissions (TM1, TM2).
