  • TORQUE MODIFICATION DURING AN UPSHIFT IN A HYBRID VEHICLE
    Publication number: 20180029587
    Abstract: A control system is provided to account for differences in engine response times and motor response times during an upshift in a transmission. A vehicle includes a driveline that has an engine, a traction motor, and a transmission selectively connected in series. A control area network (CAN) connects a plurality of controllers. At least one of the controllers is programmed to, during an upshift in the transmission, output signals over the CAN to reduce torque of the traction motor. The controller also reduces the engine torque based on signal delays in the CAN.

  • SYSTEM AND METHOD FOR DETERMINING ENGINE PULL-UP THRESHOLD
    Publication number: 20180009433
    Abstract: A system and method for modifying the engine pull-up (EPU) logic within a hybrid vehicle based on max motor torque that accounts for the drop or change in available motor torque due to the opening/slipping of a torque converter bypass clutch during engine starts is disclosed. An engine pull-up threshold is determined from max available motor torque at a virtual impeller speed, where the virtual impeller speed is the impeller speed that would result if the torque converter bypass clutch was open/slipping and transferring the same amount of torque.

  • Method and system for engine torque control
    Patent number: 9840974
    Abstract: Methods and systems are provided for improving vehicle torque control accuracy. Data points of an engine torque data set are adjusted en masse by an on-board vehicle controller while also being adjusted individually by an off-board controller. By adjusting engine operation based on a torque data set that is updated by each of the on-board and off-board controllers, engine torque errors can be reliably determined and compensated for.

  • Power split hybrid electric vehicle motor torque control using state estimation
    Patent number: 9809213
    Abstract: A vehicle includes a traction motor coupled to a driveline. An engine and a generator are coupled to the driveline through a planetary gearset. A controller commands the traction motor torque based on a difference between a driver torque demand and an estimated powertrain torque. The estimated powertrain torque is based on an error between actual and estimated engine speed and an error between actual and estimated generator speed. The estimated powertrain torque may be further based on commanded or estimated engine torque and generator torque. The estimated powertrain torque may utilize a state estimator to calculate internal states based on the errors.
