    摘要: A system for a vehicle includes a powertrain system including an engine, a transmission, a drive shaft, and a final drive; and a controller communicably coupled to the powertrain system. The controller is structured to: receive a shift schedule for the transmission of a vehicle, the shift schedule indicating when shift events occur based on operation of the vehicle; receive vehicle operation data during operation of the vehicle, the vehicle operation data including a current combustion recipe for the engine; determine a predicted impact of a scheduled shift event on a fuel consumption rate of the vehicle based on the current combustion recipe for the engine; determine an adjustment to the scheduled shift event based on the predicted impact; and provide a command to implement the adjustment to the scheduled shift event to the transmission of the vehicle.

    摘要: A shift control system and a shift control method perform shift control of an automatic transmission in a vehicle that includes a catalyst and an air-fuel ratio detector. The shift control system includes an operation detector that detects an operation corresponding to a drivel's request for stopping of the vehicle, and a condition detecting/estimating unit that detects or estimates a condition of at least one of the catalyst and the air-fuel ratio detector. In the shift control system and shift control method, if the operation corresponding to the driver's request for stopping of the vehicle is detected when an operation to switch the automatic transmission from a non-driving range to a driving range is selected is performed, the automatic transmission is controlled so that driving force of the engine is not substantially transmitted to the driving wheels, based on the detected or estimated result of at least one of the catalyst and the air-fuel ratio detector.

    摘要: A method and system for controlling torque disturbances in direct injection stratified charge and lean burn port-fuel injection engines (12) through continuously variable transmission (40). The method and system include using the continuously variable transmission (40) to mitigate the effects of torque disturbances due to a lean NOx trap (22) purge cycle (100). The continuously variable transmission (40) is coordinated with other engine variables, such as throttle (36), fueling rate (Wf), injection timing (&ggr;), and spark timing (&dgr;), to keep the operation near the optimal regime. In periods of trap (22) purge, the engine control variables and the continuously variable transmission (40) are coordinated to maximize purge efficiency for a predetermined period of time. In periods of normal operation (102), the engine control variables and the continuously variable transmission (40) are coordinated to minimize fuel consumption subject to emission constraints.
