摘要： A method of operating a motor vehicle transmission includes measuring an operating temperature of the transmission, the transmission having at least seven torque transmitting mechanisms and at least three planetary gear sets, each planetary gear set having three gear members; determining if the transmission is in a park mode; determining if the operating temperature is below a predetermined threshold; if the operating temperature is below the predetermined threshold and the transmission is the park mode, implementing a shift delay mitigation process that includes engaging a fourth torque transmitting mechanism and a firth torque transmitting mechanism of the at least seven torque transmitting mechanisms so that they are locked to a ground to prevent a first gear member of the first planetary gear set from moving, which, in turn, prevents an input torque being transferred to a park pawl.

摘要： 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.

摘要： A method for determining a transmission range selection of a shift-by-wire system, which includes a shift lever, a park button, and a controller, is provided. The shift lever is movable between a plurality of transmission range positions, each corresponding to a transmission range, and a null position. The park button is switchable between a pressed position corresponding to a Park transmission range, and a released position. The method includes determining, by the controller, if at least one predetermined condition exists. If it does, then the controller determines the transmission range selection to be the Park transmission range. Otherwise, the controller determines the transmission range selection to be the transmission range corresponding to the transmission range position in which the shift lever is positioned.

摘要： An apparatus for manually shifting an automatic transmission can include a lever assembly, a coupling member and a lock arrangement. The lever assembly can include a variable length lever. The coupling member can be connected at a first end to the lever assembly and can be adapted to be coupled at a second end to a shift lever of the transmission. The lock arrangement can be associated with the lever assembly, and can be configured to provide for selective movement of the variable length lever between a stowed position having a first length and a deployed position having a second length greater than the first length. Actuation of the lever assembly can be adapted to move the shift lever to manually release a parking lock of the automatic transmission.
