Embodiment Construction
[0030] The following description relates to systems and methods for operating a driveline of a hybrid vehicle. Figure 1A to Figure 4 An exemplary hybrid vehicle system is shown that includes a driveline with a motor, an integrated starter / generator, a dual clutch transmission, and an electric machine / electric machine downstream of the dual clutch transmission. Figure 5 to Figure 8 Describes and illustrates the manner of operation for engaging and disengaging a park state in a dual clutch transmission. Figure 9 with Figure 10 A manner of controlling a hybrid vehicle powertrain that may improve vehicle stability is described. can be used as Figure 11-17B The clutches of the dual clutch transmission are adapted and used during shifting of the dual clutch transmission. The engine that can start a hybrid vehicle can be started and engaged to Figures 18A-19B Other components of the hybrid vehicle driveline are described.

Methods and systems are provided for operating a driveline of a hybrid vehicle powertrain, wherein the driveline includes an electric machine downstream of a dual clutch transmission, which is downstream of an engine. In one example, a method comprises communicating from a transmission, a torque to accelerate transmission components from a first speed to a second speed with first and second clutches of a dual transmission open, the communicating performed while an electric machine coupled to the dual clutch transmission at a location downstream of the dual clutch transmission is providing torque to propel a vehicle. In this way, wheel speed may remain substantially constant while the transmission is shifted and the engine is stopped.

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 415,392, filed October 31, 2016, entitled "Methods and System for a Hybrid Vehicle," the entire contents of which are hereby incorporated by reference in their entirety for for all purposes. technical field [0003] The present description generally relates to methods and systems for controlling a driveline of a hybrid vehicle. These methods and systems may be particularly useful for hybrid vehicles including dual clutch transmissions. Background technique [0004] For hybrid vehicles utilizing an internal combustion engine, a dual-clutch or automatic manual transmission, and an electric motor behind the transmission that transfers torque to the driven wheels, there may be a powertrain mode that uses only the electric motor to propel the vehicle with the transmission input clutch open, which allows The engine is stationary. If the vehicle...
