Abstract
Methods and systems for extending range and functionality of an electrified vehicle are described. In one example, a two-way clutch allows a vehicle to move in a forward or reverse direction under power of an electric machine. The electric machine may be operated as a generator and as a motor.
Claims20
A vehicle system, comprising:
- a first axle;
- a transmission including a planetary gear set mechanically coupled to the first axle, the planetary gear set including a sun gear, a ring gear, and a planetary carrier assembly configured to support planetary pinion gears;
- an internal combustion engine;
- a two-way clutch positioned between the internal combustion engine and the planetary carrier assembly;
- and
- a first electric machine coupled to the transmission.

A method for operating a vehicle, comprising:
- adjusting an operating state of a two-way clutch in response to a position of a shifter, the two-way clutch positioned between a planetary carrier assembly and an internal combustion engine.
A vehicle system, comprising:
- a first axle;
- a transmission including a planetary gear set mechanically coupled to the first axle, the planetary gear set including a sun gear, a ring gear, and a planetary carrier assembly configured to support planetary pinion gears;
- an internal combustion engine;
- a two-way clutch positioned between the internal combustion engine and the planetary carrier assembly;
- a first electric machine coupled to the transmission;
- and
- a controller including executable instructions stored in non-transitory memory that cause the controller to operate the vehicle system in four different operating modes including electric vehicle forward four wheel drive mode, electric vehicle reverse four wheel drive mode, engine cranking mode, and engine on mode.
