摘要： A vehicle includes a starter motor, an engine having an output mechanically coupled to the starter motor, a transmission having an input, and an electric machine mechanically coupled to the transmission input. The vehicle further includes a clutch configured to mechanically couple the electric machine and the output of the engine, and at least one controller. The at least one controller is programmed to initiate an engine start based on driver demand. The controller is further configured to enable pressure to the clutch for the engine start if driver demand is less than a calibratable torque value or enable the starter motor for the engine start if the driver demand is greater than a calibratable torque value. The controller may lock the clutch to the output of the engine in response to the speed of the engine being approximately equal to the speed of the electric machine.

摘要： A vehicle includes an engine having a crankshaft, a transmission having an input, and an electric machine mechanically coupled to the transmission input. The vehicle further includes a clutch configured to mechanically couple the electric machine and engine crankshaft, and at least one controller. The at least one controller, in response to an engine start condition and subsequent partial engagement of the clutch, outputs a torque command for the electric machine to increase the speed of the crankshaft to a speed of the electric machine before commanding fuel injection of the engine. The torque command is based on driver demanded torque and a change in speed of the crankshaft caused by changes in pressure to the clutch.

摘要： A vehicle is provided with a powertrain including an electric motor, an internal combustion engine, and a turbocharger. The vehicle further includes a controller programmed to apply a variable filter to engine torque commands that are responsive to driver demand. The filter affects commands having a rate of increase greater than a predetermined threshold such that corresponding rates of increase in both engine torque and turbocharger speed are limited to respective rates less than the maximum available levels in order to reduce a surge in engine output emissions. The controller additionally issues commands for motor torque such that overall powertrain torque satisfies the driver demand.

摘要： A system and method for controlling battery power in a hybrid vehicle for a given driver demand that balances battery state of charge and battery capacity limits while operating the engine at a system efficient engine power. Predictive information may be used to predict battery energy usage during a future time window that indicates a charging opportunity (excess power will be absorbed by the battery) or a boosting opportunity (battery power will be discharged). Based on this information and the current state of charge of the battery, an associated battery power for a given driver demand is determined.
