DRIVE SYSTEM FOR AUTOMOBILE AND METHOD FOR CONTROLLING DRIVE SYSTEM FOR AUTOMOBILE

摘要

Disclosed is a drive system (1) for an automobile, wherein the system is provided with first and second engines (ENG1, ENG2), first and second transmissions (TM1, TM2), first and second oneway clutches (OWC1, OWC2) respectively provided in output units of the first and second transmissions (TM1, TM2), a rotated/driven member (11) commonly linked to output members (121) of the first and second oneway clutches (OWC1, OWC2), and a control means (5). Under the conditions that the power generated by the first engine (ENG1) is input through the first oneway clutch (OWC1) to the rotated/driven member, namely, driving is performed by the first engine (ENG1), the control means switches from driving by the first engine (ENG1) to driving by the second engine (ENG2) by changing the number of rotations of the second engine (ENG2) and/or by changing a change gear ratio of a second gear shift mechanism so that the number of rotations to be input to the input member of the second oneway clutch (OWC2) is greater than the number of rotations of the output member. Thereby, a drive system for an automobile and a method for controlling a drive system for an automobile achieving high efficiency and an improved fuel efficiency can be provided.
