Abstract: A vehicle includes a powertrain, an inertial measurement unit configured to measure inertial forces exerted onto the vehicle, and a controller. The controller is programmed to control the torque at the powertrain based on a mapped relationship between the inertial forces and a vehicle velocity, wherein the mapped relationship utilizes at least one mapping parameter. The controller is further programmed to estimate a mass of the vehicle based on the mapping parameter.

Abstract: Methods and system are described for changing a driveline gear range from a higher gear range to a lower 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 higher gear range to a lower gear range without stopping a vehicle.

Abstract: Methods and systems are provided for operating a vehicle that includes a torque vectoring electric machine. In one example, torque output of a torque vectoring electric machine is adjusted to reduce driveline torque disturbances when the torque vectoring electric machine is activated. The torque output is adjusted in response to a speed difference between a wheel speed and a speed of the torque vectoring electric machine.

Abstract: Systems and methods for starting an engine of a hybrid vehicle are disclosed. The systems and methods disclosed may apply to series or parallel hybrid driveline configurations. In one example, engine cranking torque may be adjusted in response to a variety of operating conditions so that the engine may be started faster or slower.

Abstract: A method of controlling a Continuously Variable Transmission (CVT) simulates a step-ratio transmission upshift. To simulate a step-ratio torque phase, the input torque is gradually reduced before beginning to change the variator ratio. Then, as the variator ratio is changed, the input torque is gradually increased to compensate for the decreasing torque ratio, simulating the relatively constant output torque of an inertia phase of a step-ratio upshift.

Abstract: Methods and systems for improving operation of a vehicle driveline that includes an engine and an automatic transmission with a torque converter are presented. In one non-limiting example, the engine may be stopped while a vehicle in which the engine operates is rolling. A transmission coupled to the engine may be shifted as the vehicle rolls so that vehicle response may be improved if a driver requests an increase of engine torque.

Abstract: A method of starting a vehicle may include providing power to a motor to spin the motor at a speed at least equal to a target engine cranking speed while a clutch configured to couple an engine and motor is open. The method may also include cutting power to the motor in response to the motor achieving the speed, and locking the clutch to couple the rotating inertias of the motor and a transmission with the engine to start the engine.
