Abstract: A method of operating a hybrid electric vehicle coordinates operation of an internal combustion engine, a motor, and friction brakes to mitigate a driveline lash crossing without delaying generation of negative torque. In response to a request to transition from positive torque to negative torque, the engine and motor are controlled to rapidly reduce powertrain torque to a small positive value, slowly reduce powertrain torque through the driveline lash zone, and then rapidly reduce powertrain torque to the target. To avoid delay, the friction brakes are applied in a coordinated manner to supply the negative torque during the transition.

Abstract: Systems and methods for improving transmission gear shifting of a hybrid vehicle are presented. The systems and methods prepare the hybrid vehicle for conditions that may occur after a requested gear shift is performed. In one example, a motor speed that would occur after a downshift, if the downshift were allowed to occur, is determined and control actions may be taken in response to the predicted motor speed.

Abstract: A selectively actuatable one-way clutch is controlled to brake or release a generator such that a powersplit hybrid powertrain enters or exits a parallel mode of operation. To brake the generator and enter the parallel mode, the clutch is activated while overrunning the generator before the generator is slowed to engage the clutch. To release the generator and exit the parallel mode, the generator is controlled to overrun the clutch before deactivating the clutch and returning the generator to a base speed control.

Abstract: A hybrid electric vehicle includes an engine and an electric machine for providing propulsion forces to wheels of the vehicle. In an electric-only propulsion mode, the engine is disabled and the electric machine acts as the power source for the wheels. In a hybrid propulsion mode, the engine is activated to act as an additional power source for the wheels. At least one controller along with a plurality of sensors and positional information devices activate an active safety control signal in response to objects surrounding the vehicle that pose a threat to a potential collision event. In response to the active safety control signal, the engine can be either automatically started or stopped to provide additional available power or a reduced available power, respectively.

Abstract: A vehicle includes a power source, such as an engine, an electric machine, or combination thereof. A torque converter is selectively coupled to the power source such that drive torque can be altered before being distributed into a transmission of the vehicle. A torque converter bypass clutch enables torque from the power source to selectively transmit directly to the transmission with little or no torque altering provided by the torque converter. At least one controller in the vehicle is in communication with a storage device. The controller sends road condition data to the storage device regarding a road segment. During a subsequent drive to or over the road segment, the controller receives the road condition data and enables the torque converter bypass clutch to slip to dampen driveline disturbances when the vehicle passes over the road segment.

Abstract: A system and method for controlling a vehicle having an electric traction motor coupled to a transmission by a clutch include modifying torque transmitted to the driveline by modifying the clutch apply pressure in response to a difference between rotational speed of a driveline component and a filtered rotational speed of the driveline component to reduce driveline oscillation when the clutch is unlocked. The clutch pressure may be modified in response to a vehicle event that may otherwise induce driveline oscillations, such as a transmission ratio change or regenerative braking, for example.
