Abstract: Methods and systems are provided for operating a driveline of a hybrid vehicle powertrain, where 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.

Abstract: A controller of a vehicle that includes a return control unit configured to carry out a complete engagement control of a power connecting/disconnecting device. At the time a return condition from inertia traveling to normal traveling is established and a down shift of an automatic transmission is requested, the return control unit carries out a down shift control of the automatic transmission so that a difference between an increasing gradient of a rotating speed of a first engaging portion and an increasing gradient of a rotating speed of a second engaging portion is within a predetermined range. At the time it can be regarded that the rotating speed of the first engaging portion and the rotating speed of the second engaging portion are synchronized, the return control unit completely engages the power connecting/disconnecting device.

Abstract: Methods and systems are provided for controlling clutch capacity in a hybrid electric vehicle. In one example, a method includes adjusting values of a transfer function of a clutch of a dual clutch transmission in response to an operating condition of an engine and/or operating condition of an integrated starter/generator coupled to the engine while a vehicle is propelled via an electric machine coupled to the dual clutch transmission, and maintaining a driver demand wheel torque at vehicle wheels via adjusting torque of the electric machine in response to the operating condition of the engine and/or operating condition of the integrated starter generator. In this way the method may apply pressure to one of the clutches where engine speed is independently controlled to maintain positive or negative slip, thus enabling adaptation of positive and negative clutch transfer functions, which may improve driveline operation and shift quality.

Abstract: A powertrain includes an engine, a transmission, and one or more accessories, such as an alternator or an air conditioning compressor, all operating based on commands from a controller. The controller is programmed to coordinate commands to the transmission with commands to the accessories to mitigate the impacts of transmission state changes. The accessory drive torque may be adjusted to compensate for the torque required to change the speed of a transmission internal shaft. The accessory effective inertia may be adjusted to maintain a powertrain natural frequency so that active damping can be maintained throughout a transmission state change event.

Abstract: A vehicle includes an engine, an automatic transmission, and a controller. The transmission includes a neutral idle (NI) state and a designated NI clutch which is selectively actuated to exit the NI state. The controller executes instructions from tangible memory to shift out of the NI state and into a drive state. The controller includes a slip model which generates a desired clutch slip profile as a differentiable time function, and a desired slip derivative of the desired slip profile. The desired profiles are used to calculate a clutch pressure command for controlling the designated NI clutch. The time function may be at least a third order/cubic equation. A method includes executing the slip model to generate the desired clutch slip profile, calculating a desired slip derivative of the desired slip profile, and using the desired slip profile derivative to calculate a clutch pressure command for the designated NI clutch.
