Abstract:
1. A vehicle driving system including: a first internal combustion engine section and a second internal combustion engine section that generate rotational powers, respectively; a first transmission mechanism and a second transmission mechanism that output the generated rotational powers of the first internal combustion engine section and the second internal combustion engine section while changing speeds thereof, respectively; a first one-way clutch and a second one-way clutch that are provided in output portions of the first transmission mechanism and the second transmission mechanism, respectively, each one-way clutch having: a driving target member that is commonly connected to the output members of the first one-way clutch and the second one-way clutch and transmits the rotational power to be transmitted to the output members of each one-way clutch to a driving wheel, wherein the generated rotational powers of the first internal combustion engine section and the second internal combustion engine section are input to the first one-way clutch and the second one-way clutch via the first transmission mechanism and the second transmission mechanism, respectively, and the rotational powers are input to the driving target member via the first one-way clutch and the second one-way clutch, respectively, wherein each of the first transmission mechanism and the second transmission mechanism includes: wherein each of the first transmission mechanism and the second transmission mechanism are configured as four bar linkage mechanism type of continuously variable transmission mechanism that can set the transmission ratio to infinity by setting the eccentricity to be zero, and wherein a clutch mechanism that can transmit/disconnect the power between at least one of the output members of the first and second one-way clutches and the driving target member.
