Abstract: A vehicle includes a pair of electric machines each coupled to a laterally-opposing wheel to output a wheel torque. The vehicle also includes a controller programmed to command a combined regenerative braking torque output of the electric machines based on a lesser of a braking torque limit of each individual electric machine. The controller is also programmed to command a regenerative braking torque from each electric machine to be within a predetermined torque threshold of each other in response to a yaw rate exceeding a yaw threshold.

Abstract: A method of controlling a hybrid vehicle includes commanding a first electric machine to provide a compensating torque. The compensating torque is based on a calculated cylinder pressure. The calculated cylinder pressure is calculated using a dynamic model. The model has an initializing input of engine crank position and real-time inputs of measured speed of the first electric machine and measured speed of the second electric machine.

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 systems are provided for operating a hybrid vehicle during operating conditions where vehicle braking is requested. In one example, regenerative braking is allocated to vehicle wheels responsive to actual and estimated vehicle yaw. Additionally, friction braking torque is allocated to vehicle wheels responsive to requested braking torque and regenerative braking torques.

Abstract: An autonomous or semi-autonomous vehicle is provided that is capable of braking itself without a driver depressing the brake pedal. The vehicle has a powertrain that includes an engine, a transmission, and a motor with a connected battery to provide regenerative braking capabilities. Friction brakes are provided to apply when necessary, such as when the battery has a high state of charge and further regenerative braking would overcharge the battery. The braking may be activated in response to a sensor detecting a distance to an object in front of the vehicle. A vehicle controller is programmed to automatically control amounts of regenerative braking and friction braking during a braking event based on a comparison between a regenerative torque limit of the powertrain and a desired brake torque over the brake event to safely brake the vehicle during the brake event.

Abstract: A shift strategy is provided for a hybrid electric vehicle to cause a speed of a motor to approach a target motor speed to increase fuel economy for an engine operating in a hybrid drive mode. A controller shifts the transmission according to a magnitude of a driver torque demand, the current rotor or impeller speed, and whether the motor is consuming or producing current. The controller shifts the transmission according to one shift schedule when the motor is motoring, and according to another shift schedule when the motor is generating power.

Abstract: A hybrid electric vehicle includes an engine, an electric machine, and a battery, coupled to a controller(s) configured to, in response to a virtual-driver signal, predict and maintain a constant-speed from a plurality of candidate speeds, to have a lowest fuel consumption and a minimum number of battery-charge-cycles, for a predicted distance and wheel-torque-power. A predicted engine-power is established from the wheel-torque-power required to maintain the constant-speed, and to power vehicle accessories and battery charging, such that fuel consumption and battery-charge-cycles are minimized over the predicted distance at the constant-speed. The controller(s) are configured to generate the predicted distance, from one or more of position and moving-map sensors, by detecting a current location, and identifying an open-road distance between the current location and at least one detected and/or predetermined way-point. The constant-speed is also determined by evaluating travel-times and battery-charge-discharge cycles for the constant speed over the predicted distance.

Abstract: A vehicle includes an engine and an electric machine coupled to a gearbox through a torque converter. The vehicle includes a controller programmed to command an engine torque and an electric machine torque to achieve a predetermined positive torque at the input of the torque converter when a driver demand torque at the torque converter input decreases to fall within a range between the predetermined positive torque and a predetermined negative torque.
