Abstract: Systems and methods for improving operation of a hybrid vehicle driveline are presented. In one example, pressures applied to two different clutches are coordinated such that a pressure boost phase of a driveline disconnect clutch does not occur at a same time as a pressure boost phase of a transmission shifting clutch.

Abstract: A vehicle may include an engine selectively coupled to a motor and a transmission. The vehicle may include a controller configured to, in response to actuation of a brake pedal, command the transmission to downshift during a regenerative braking event based on a regenerative braking downshift torque. The regenerative braking downshift torque may be determined from a predicted brake pedal input rate. The predicted brake pedal input rate may be based on road grade, vehicle headway range and a driver history. The predicted brake pedal input rate may be classified as Low, Medium, or High. The regenerative braking downshift torque may also be determined from a predicted brake torque rate that is based on a predicted deceleration rate of the vehicle, a vehicle speed prediction and a road grade prediction within a future time interval that begins upon actuation of the brake pedal.

Abstract: A vehicle includes an electric machine, battery, torque converter bypass clutch, drive wheel, and controller. The electric machine is configured to recharge the battery via regenerative braking. The torque converter bypass clutch is disposed between the electric machine and the drive wheel. The controller is programmed to, in response to a negative drive wheel torque command during a regenerative braking event, adjust a closed-state torque capacity of the torque converter bypass clutch based on the torque command.

Abstract: A hybrid vehicle includes an engine, an electric machine, a transmission, and a controller. The transmission is configured to alter clutch pressures in preparation for an upcoming shift between discrete gear ratios (e.g., input-to-output ratio). For example, the clutch pressures may spike to a heightened magnitude to prepare for the upcoming shift. The electric machine is configured to selectively propel the vehicle and perform regenerative braking. If regenerative braking demands occur during the clutch pressures being heightened during shift preparation, the controller is programmed to stop the preparing of the clutches. This can be done by reducing the clutch pressures back to their pre-preparation magnitude. The upcoming shift can be cancelled or delayed.

Abstract: A vehicle includes an engine having a crankshaft, a transmission, an electric machine, and at least one controller. The transmission includes a torque converter having a turbine fixed to a turbine shaft that is driveably connected to driven wheels of the vehicle. The torque converter includes an impeller and a bypass clutch configured to selectively lock the impeller and the turbine relative to each other. The electric machine includes a rotor selectively coupled to the crankshaft via a disconnect clutch and fixed to the impeller. The at least one controller is configured to generate a first torque command for the electric machine that defines a magnitude equal to driver-demanded torque while the bypass clutch is locked. The controller is further configured to, in response to a reduction in fluid pressure supplied to the bypass clutch, generate a second torque command for the electric machine that defines a magnitude equal to driver-demanded torque plus impeller inertia torque.

Abstract: A vehicle powertrain includes a controller, a torque converter, and an engine and electric machine coupled by a clutch. The torque converter may be configured to couple the electric machine to an output shaft. The controller may be programed to generate a command for the electric machine to output torque to drive the torque converter toward a desired rotational speed, and to modify the command according to a difference between the desired rotational speed and an actual rotational speed to reduce the difference, wherein values of the difference are limited by thresholds that change with powertrain operation.

Abstract: A system and method for controlling a transmission gear shift in a vehicle having a driveline and an electric motor operable to output torque to the driveline includes applying a negative motor torque to the driveline to reduce driveline oscillations resulting from the transmission gear shift. The negative motor torque is based on vehicle conditions occurring after the transmission gear shift has begun and before the transmission gear shift is complete.

Abstract: A vehicle includes a traction battery and a controller. The controller, in response to termination of current flow from the traction battery to a tool that is plugged in to the vehicle that results in shutting down of the tool, actuates a switch such that current resulting from the shutting down flows from the tool to the traction battery for regenerative energy capture.

Abstract: A vehicle includes a generator, a battery, a transmission, and a controller. The generator is configured to recharge the battery at a maximum power output when a generator speed is above a threshold speed. The transmission is configured to downshift during regenerative braking such that the generator speed is maintained above the threshold speed. The controller is programmed to, in response to a decrease in battery temperature corresponding to a decrease in generator speed required to maintain the maximum power output, decrease the threshold speed.

Abstract: A vehicle includes an engine, a motor selectively coupled to the engine, a transmission selectively coupled to the motor, and a controller. The motor is able to operate as a motor (to provide torque to the transmission) and a generator (to charge a battery). In one mode, the controller can command the engine to both propel the vehicle and provide torque to the motor to charge the battery. The controller estimates the maximum available engine torque in the current gear and maintains the vehicle in the current gear of the transmission. And, the controller commands the motor to charge the battery by a magnitude based on the difference between driver demanded torque and an estimated maximum available engine torque in a current gear of the transmission. This allows the engine to operate at (or near) its maximum torque output to fulfill driver demands and charge the battery while inhibiting downshifting.
