Abstract: A method for operating a vehicle that may be automatically stopped and started is described. In one example, the method includes starting an engine via expansion stroke combustion in response to a request to urgently start the engine. In addition, the method includes adjusting a position of a compression relief valve in response to a predicted urgency of an engine start.

Abstract: A vehicle includes an electric machine, friction brakes, a drivetrain, and a controller. The electric machine is configured to recharge a battery during regenerative braking. The friction brakes are configured to apply torque to wheels of the vehicle to slow the vehicle. The controller is programmed to, in response to and during an anti-locking braking event, generate a signal indicative of a total torque demand to brake the vehicle based on a difference between a desired wheel slip ratio and an actual wheel slip ratio, adjust a regenerative braking torque based on a product of the signal and a regenerative braking weighting coefficient, adjust a friction braking torque based on a product of the signal and a friction braking weighting coefficient, and further adjust the regenerative braking torque based on a closed-loop control of an estimated regenerative braking torque feedback.

Abstract: A system and method for controlling a hybrid vehicle having an engine selectively coupled by an upstream clutch to an electric machine, which is selectively coupled by a downstream clutch to a step-ratio transmission, include at least one controller programmed to control the engine and the electric machine in response to entering a lash zone in anticipation of a wheel torque reversal to adjust a gain applied to an active motor damping torque controller to reduce driveline oscillations and backlash.

Abstract: A hybrid electric vehicle having a powertrain including an engine and an electric machine, and controllers configured to derate powertrain output torque below a nominal maximum to a fault-torque limit, in response to a vehicle fault or issue. The vehicle and controllers are also configured to transiently increase powertrain torque output above the fault-torque limit in response to a torque demand that exceeds the limit, and which is needed to enable a predicted vehicle maneuver. The controller also establishes a predicted duration for the predicted interim vehicle maneuver and for override of the fault-torque limit and delivery of the additional torque from the torque-demand signal and other signals. The predicted duration includes a time span to maneuver through roadway obstacles and traffic, but does not exceed a limited operation time or a limited power output established by the controller from the vehicle issue or fault identified by the fault signal.

Abstract: Systems and methods for operating a driveline of a hybrid vehicle are disclosed. In one example, powertrain output is limited or constrained so that powertrain output variation is limited to a desired level at different altitudes. The powertrain output may be constrained based on a ratio of a threshold electric machine torque to a threshold engine torque.

Abstract: A controller and a control strategy minimizes shift shock in a hybrid electric vehicle during a downshift conducted while the vehicle is in a regenerative braking mode by maintaining total powertrain torque at a desired target during the downshift. The controller has three preferable modes including modulating just engine torque, modulating just electric motor torque or simultaneously modulating both motor and engine torque.
