Abstract
A vehicle comprises a drive sub-system having an engine and a first motor and a generator sub-system having a transmission and a second motor. The transmission for the vehicle is driven with the first motor, the second motor and the engine individually and in combination such that the vehicle may selectively operate in a serial hybrid mode and a parallel hybrid mode.
Claims19
A vehicle comprising:
- an internal combustion engine;
- a first motor driveably connected to the engine, wherein the engine and the first motor selectively operate as a generator sub-system for the vehicle;
- a transmission to drive the vehicle;
- a second motor driveably connected to the transmission, wherein the transmission and the second motor selectively operate as a drive sub-system for the vehicle;
- and
- a first clutch connected to the first motor to selectively operatively engage the generator sub-system with the drive sub-system.
