Abstract: A controller commands an engine torque level in response to a driver demanded torque based on an accelerator pedal position. If the driver demanded torque decreases rapidly during or just prior to a torque phase of a shift, the controller commands the engine to temporarily generate torque exceeding the driver demand. The controller sets a nominal engine torque equal to the driver demand torque before the rapid decrease, slowly decreases the nominal engine torque during the torque phase, and decreases the nominal torque at progressively faster rates during the inertia phase to bring the nominal torque back into agreement with the driver demanded torque. The commanded engine torque is based on the nominal torque, but may be less than the nominal torque during the inertia phase to permit the engine speed to decrease faster.

Abstract: A vehicle powertrain includes an engine and a transmission coupled to the engine. The transmission has a first neutral state in which a first combination of clutches are engaged and a second neutral state in which a second combination of clutches are engaged. A vehicle controller is programmed to, in response to the transmission being in the first neutral state and an engine-torque request exceeding a threshold value, shift the transmission to the second neutral state.

Abstract: A hybrid drive system has a battery and a combustion engine for energy sources. The system has a traction motor, a generator, a variable voltage converter (VVC), a motor inverter, a generator inverter, a bus coupling the VVC to the inverters, and a controller. The controller regulates engine speed, motor torque, and generator torque. The engine speed is determined according to a driver torque demand. In normal conditions, 1) the controller regulates the engine speed by modifying a generator torque command, and 2) the bus voltage is regulated using the VVC and battery. When the controller detects a fault in which the battery and VVC become unavailable for regulating the bus voltage, then the controller regulates a motor inverter power output to match a sum of a generator inverter power output and an estimated power loss of the inverters in order to regulate the bus voltage.

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.
