Abstract
An electrified vehicle torque transfer system includes, among other things, an engine having an engine shaft, an electric machine having an electric machine shaft, a first clutch that is selectively engaged to rotatably couple together the engine shaft and the electric machine shaft such that the engine can drive rotation of the electric machine, and a second clutch that is selectively engaged to rotatably couple together the engine shaft and the electric machine shaft such that the electric machine can drive rotation of the engine.
Claims19
An electrified vehicle torque transfer system, comprising:
- an engine having an engine shaft;
- an electric machine having an electric machine shaft;
- a first clutch that is selectively engaged to rotatably couple together the engine shaft and the electric machine shaft such that the engine can drive rotation of the electric machine, the first clutch configured to rotate about a first axis when engaged;
- and
- a second clutch that is selectively engaged to rotatably couple together the engine shaft and the electric machine shaft such that the electric machine can drive rotation of the engine, the second clutch configured to rotate about a second axis when engaged, the first axis different than the second axis.
A torque transfer method for an electrified vehicle, comprising:
- driving an electric machine shaft with an engine shaft by transferring torque from the engine shaft, through a first clutch, to the electric machine shaft;
- and
- driving the engine shaft with the electric machine shaft by transferring torque from the electric machine shaft, through a second clutch, to the engine shaft, the first clutch rotating about a first axis when engaged, the second clutch rotating about a second axis when engaged, the first axis different than the second axis.
