Abstract: A hybrid electric vehicle has a traction motor, a driveline connected to a vehicle wheel, and a controller. The controller is configured to control motor torque through a region surrounding vehicle wheel torque reversal, control driveline input torque during torque reversal of driveline output torque to limit rate of change of driveline output torque, and control motor torque during a torque reversal of at least one driveline component to limit rate of change of the torque applied to the driveline component. A method for controlling a vehicle having a traction motor includes controlling the traction motor torque through a region surrounding a vehicle wheel torque reversal, controlling driveline input torque during torque reversal of driveline output torque to limit rate of change of output torque, and controlling traction motor torque during a torque reversal of a powertrain component to limit rate of change of the torque applied to the component.

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: Systems and methods for operating an engine that may selectively enter and exit a fuel cut-off mode are described. In one example, the method holds the engine in the fuel cut-off mode even though a propulsive effort pedal is applied. An electric machine may provide torque to a vehicle driveline while the engine is in the fuel cut-off mode.

Abstract: A vehicle includes a traction battery and a controller. The controller, responsive to a command to enter a highway, confirmation the traction battery can output power to accelerate the vehicle to enter the highway via an entrance at a same speed as traffic on the highway in a vicinity of the entrance, and an increase in temperature beyond a threshold of the traction battery predicted to occur on the highway due to expected commands to maintain the same speed on the highway with power from the traction battery, increases cooling of the traction battery prior to entering the highway.

Abstract: A vehicle includes a battery, an electric machine, and a controller. The battery has a state of charge. The electric machine is configured to draw electrical power from the battery to propel the vehicle in response to an acceleration request and to deliver electrical power to the battery to recharge the battery. The controller is programmed to adjust an estimation of battery state of charge based on a feed forward control that includes a coulomb counting algorithm, a first feedback control that includes a first battery model, and a second feedback control that includes a second battery model. The controller is further programmed to control the electrical power flow between the battery and the electric machine based on the estimation of the state of charge of the battery.

Abstract: A vehicle includes an axle, an electric machine, a first wheel, a second wheel, a first friction brake, a second friction brake, and a controller. The controller is programmed to, in response to and during an anti-locking braking event, generate first and second signals indicative of a braking torque demand at the first and second wheels, respectively, based on a difference between a desired wheel slip ratio and an actual wheel slip ratio of the first and second wheels, respectively, adjust a regenerative braking torque of the electric machine based on a product of the first signal and a regenerative braking weighting coefficient, adjust a first friction braking torque based on a product of the first signal and a friction braking weighting coefficient, and adjust a second friction braking torque based on the second signal and dynamics of the first and second output shafts.

Abstract: Systems and methods for improving operation of a driveline disconnect clutch for a hybrid vehicle shifting are presented. In one example, pressure of a working fluid supplied to the driveline disconnect clutch is adjusted in response to a rate of change in accelerator pedal position. Further, pressure of the working fluid may be decreased responsive to selected operating conditions.

Abstract: A vehicle includes motors each configured to drive a front wheel of the vehicle, an electronic limited slip differential (eLSD) between rear wheels of the vehicle, and a controller to, responsive to vehicle turning and a power of each of the motors being less than a maximum value, alter operation of the motors to increase a difference between the powers. Otherwise, the controller operates the eLSD to bias torque toward one of the rear wheels.

Abstract: Systems and methods for operating a hybrid powertrain that includes an engine and a motor/generator are described. The systems and methods align in time an estimated motor torque and an actual motor torque to provide an estimated driveline torque. The alignment compensates for communications delays between different controllers over a controller area network.

Abstract: A vehicle includes an engine having a crankshaft, a transmission having an input, and a torque converter mechanically coupled to the input. The vehicle further includes an electric machine mechanically coupled to the torque converter, a clutch configured to mechanically couple the electric machine and crankshaft, and one or more controllers. The one or more controllers are programmed to, in response to the transmission being in a drive or reverse gear and a speed of the vehicle being less than a predetermined value in an absence of driver demand, control the electric machine to achieve a target speed to cause the torque converter to output torque such that the speed of the vehicle approaches a generally constant speed less than or equal to the predetermined value when the vehicle is on a generally flat grade.
