Embodiment Construction

[0057] Referring now to the drawings, which are shown for the purpose of illustrating certain exemplary embodiments only and not for the purpose of limiting the invention, figure 1 A hybrid powertrain system including internal combustion engine 10 , transmission 40 , first and second torque machines 20 and 30 , respectively, is schematically illustrated, and a control module 100 is also schematically illustrated. Energy storage device 60 is electrically coupled to converter module 70, preferably via a high voltage DC bus. The inverter module 70 is electrically coupled to the first and second torque machines 20 , 30 , respectively, to convert and transmit electrical power for torque generation and electrical power generation.

[0058] Internal combustion engine 10 is mechanically coupled to transmission 40 via input member 12 and may comprise any suitable internal combustion engine. The first and second torque machines 20, 30 are machines that convert stored energy into torque...

Abstract

A hybrid powertrain system includes first and second torque machines, a differential gear set including first, second and third elements, an output member, and first, second, and third selectable one-way clutches (SOWC). The first SOWC is configurable to prevent rotation of the third element of the differential gear set in a first rotational direction when controlled to a first activated state, and configurable to prevent rotation of the third element of the differential gear set in a second rotational direction opposite the first rotational direction when controlled to a second activated state. The first torque machine is coupled to the third element of the differential gear set only when the second SOWC is controlled to one of the activated states. And, the third element of the differential gear set is coupled to the input member only when the second and third SOWCs are each controlled to one of the activated states.

Description

technical field [0001] The present disclosure relates to hybrid powertrain systems. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Known hybrid powertrain systems use torque machines that use one of two or more energy conversion processes to generate tractive torque that can be used for vehicle propulsion. Known torque machines A torque machine includes an internal combustion engine that uses a combustion process to convert fossil fuel into torque, and an electric machine that uses an electromagnetic process to convert stored electrical energy into torque. Other known torque machines may include, for example, hydraulically powered torque machines and pneumatically powered torque machines. [0004] When the powertrain is applied to a vehicle, known hybrid powertrain systems use a transmission device to transmit torque between a torque machine and ...
