Abstract: A vehicle includes an all-wheel-drive powertrain having an electric machine configured to power wheels. A controller is programmed to output a first calculated vehicle speed derived from integrating a measured longitudinal acceleration of the vehicle and output a second calculated vehicle speed based on the measured longitudinal acceleration and a speed of one of the wheels. The controller is further programmed to, responsive to a flag being present, command a speed to the electric machine that is based on the first vehicle speed to reduce wheel slip, and responsive to a flag not being present, command a speed to the electric machine that is based on the second vehicle speed to reduce wheel slip.

Abstract: A vehicle with one-pedal driving mode includes a first axle having a first electric machine configured to power first wheels and a second axle having a second electric machine configured to power second wheels. A controller is programmed to, in response to a request for one-pedal driving mode, map pedal positions of the accelerator pedal to speeds of the first and second wheels such that each of the pedal positions corresponds to a driver-demanded speed of the first and second wheels, and control one or more of the electric machine so that the vehicle is propelled according to the driver-demanded speed.

Abstract: An electrified axle system includes a pair of wheels, a super positioning torque vectoring differential coupled between the wheels, and a controller. The super positioning torque vectoring differential includes a traction motor and a vectoring motor. The controller operates the vectoring motor in speed control mode to reduce a speed difference between the wheels responsive to the difference exceeding a threshold, and operates the vectoring motor in torque control mode responsive to the difference falling within a target range and an accelerator pedal position achieving a value that depends on lateral acceleration associated with the system.

Abstract: Methods and system are described for changing a driveline gear range from a lower gear range to a higher gear range. The driveline may include two electric machines and four clutches in a four wheel drive configuration. The methods and systems permit a driveline to change from a lower gear range to a higher gear range in a way that may reduce torque disturbances that may result from gear lash.

Abstract: Methods and systems to operate a hybrid vehicle in a controlled lateral vehicle slip mode are described. The lateral vehicle slip mode may adjust torques applied to a vehicle's front wheels and operation of transmission clutches to induce lateral vehicle slip when requested. The vehicle may exit the lateral vehicle slip mode in response to applying vehicle brakes or releasing a vehicle accelerator pedal.

Abstract: A vehicle includes primary and secondary axles including primary and secondary electric machines, respectively. A vehicle controller is programmed to, responsive to a braking torque request, command regenerative torques, that are a proportion of the braking torque request, to the electric machines such that the proportion commanded to the secondary electric machine decreases responsive to lateral acceleration of the vehicle increasing.

Abstract: Methods and systems are provided for operating a vehicle in a mode to free the vehicle from being stuck in sand are presented. In one example, a speed of an electric machine is adjusted to determine when wheel jitter occurs. The electric machine speed may be maintained at a speed where wheel jitter occurs while the vehicle is stuck.

Abstract: A vehicle includes a first axle having a first electric machine, a second axle having a second electric machine and a controller. The controller is programmed to, in a user-selected four-wheel drive mode, command a first torque to the first electric machine based on a driver-demanded torque and a speed of the second axle, and command a second torque to the second electric machine based on a comparison of the driver-demanded torque and the first torque and further based on a speed of the first axle.
