Abstract: A vehicle includes a powertrain and a controller. The powertrain includes a transmission mechanically coupled to an electric machine and configured to transfer torque between a wheel and the electric machine. The transmission has a gearbox configured to establish gear ratios through a shift. The controller is programmed to, in response to an indication of an expected regenerative braking event having a timing falling within a shift window of the transmission, prevent a clutch of the transmission from disengaging until first occurrence of application of an accelerator pedal or removal of the indication to inhibit the shift prompted by a shift schedule of the gearbox.

Abstract: A vehicle comprises a hybrid powertrain includes an electric machine coupled between an automatic gearbox and an engine. The vehicle includes paddle shifters configured to output a driver requested gear change. The hybrid powertrain is configured to selectively operate in an economy mode that optimizes fuel economy. While operating in the economy mode, a controller may selectively inhibit the driver requested gear change when the change may negatively impact fuel economy. In the economy mode, the driver requested gear change may be inhibited during a demand for braking. If the driver requested gear change is a downshift request, the downshift is inhibited and simulated using electric machine torque.

Abstract: A method includes controlling a torque output of an electric machine of an electrified vehicle based on estimated loads present during a transmission engagement of the electrified vehicle. Controlling the torque output may include merging a first feed-forward torque with a feedback torque if an input shaft of a transmission gearbox is spinning, or merging a second, different feed-forward torque with the feedback torque if the input shaft is not spinning.

Abstract: A vehicle includes an engine, a traction motor, a clutch, and a controller. The clutch selectively couples the traction motor to wheels. The controller, in response to a torque output by the fraction motor achieving a torque limit while operating to partially satisfy a demand for driveline damping and while the clutch is locked, slips the clutch to completely satisfy the demand for driveline damping.

Abstract: A control system is provided to account for differences in engine response times and motor response times during an upshift in a transmission. A vehicle includes a driveline that has an engine, a traction motor, and a transmission selectively connected in series. A control area network (CAN) connects a plurality of controllers. At least one of the controllers is programmed to, during an upshift in the transmission, output signals over the CAN to reduce torque of the traction motor. The controller also reduces the engine torque based on signal delays in the CAN.

Abstract: A vehicle system may include a controller configured to increase, after a specified delay, an engagement pressure of a torque converter clutch prior to occurrence of the event to a target pressure that is based on a regenerative braking torque estimate associated with the event such that a portion of energy associated with the event is converted to electricity. The controller may increase the engagement pressure in response to an accelerator pedal release and an expected regenerative braking event.

Abstract: A vehicle includes a regenerative braking system, which may include an electric machine, configured to provide regenerative braking torque to vehicle traction wheels. The vehicle further includes at least one controller configured to provide indicia for display to indicate performance of the regenerative braking system. The indicia represent a comparison of a braking profile that is recorded during a deceleration event and a calculated braking profile that is based on a detected forward object. In various embodiments, the indicia may include a numerical or letter grade representative of a similarity between the recorded braking profile and the calculated braking profile and/or a visual representation of the comparison of the recorded braking profile and the calculated braking profile.

Abstract: Systems and methods for improving hybrid vehicle cooling are presented. In one example, an electric pump may supply transmission fluid to a transmission and a driveline integrated starter/generator to cool, operate, and lubricate driveline components. The electric pump may be selectively operated to conserve energy and to supply driveline cooling when driveline cooling may be desirable.

Abstract: A control strategy is provided for a hybrid vehicle that will increase drivability during low or decreasing driver demands. Coordination between shifting the transmission and stopping or (non-demand) starting of the engine can increase drivability. The vehicle includes a motor/generator with one side selectively coupled to the engine and another side selectively coupled to the transmission. The control strategy acts when an engine start or stop is requested while driver demand is decreasing and a shift of the transmission is demanded. To inhibit these events from proceeding simultaneously, the control strategy delays the engine from starting or stopping until the transmission has finished shifting, or vice versa.
