Abstract
Methods and systems for delivering powertrain torque of a hybrid vehicle are disclosed. In one example, torque is supplied to vehicle wheels from a piston engine, an electric machine, and a turbine engine via a planetary gear set. The planetary gear set may be configured with at least one sun gear and two ring gears.
Claims17
A hybrid vehicle powertrain, comprising:
- an engine;
- an electric machine;
- a turbine generator located along an exhaust passage of the engine;
- and
- a planetary gear set mechanically coupled to the engine, the electric machine, and the turbine generator;
- where the electric machine is a traction motor, and further comprising a first generator, the first generator mechanically coupled to the planetary gear set.

A hybrid vehicle powertrain, comprising:
- an engine;
- an electric machine;
- a turbine generator located along an exhaust passage of the engine;
- and
- a planetary gear set mechanically coupled to the engine, the electric machine, and the turbine generator, the planetary gear set including at least one sun gear and two ring gears.
2 more elements
A hybrid vehicle powertrain operating method, comprising:
- combining torque of an electric machine, a piston engine, and a turbine engine positioned along an exhaust passage of the piston engine in a planetary gear set;
- transferring torque from the planetary gear set to vehicle wheels;
- and
- receiving input from a sensor to a controller, and selectively activating one or more of the electric machine, the piston engine, and the turbine engine in response to the input from the sensor, where the electric machine is directly mechanically coupled to a ring gear of the planetary gear set.
