摘要： A hybrid vehicle powertrain includes an internal combustion engine, first and second electric machines, traction wheels, and an output shaft having meshing gears configured to establish a final drive ratio between the output shaft and the traction wheels. The powertrain additionally includes a first mechanical linkage and a second mechanical linkage. The first mechanical linkage is configured to selectively transmit engine torque to the fraction wheels and selectively transmit electric machine torque to the traction wheels. The second mechanical linkage is configured to selectively transmit engine torque to the traction wheels. When transmitting engine torque to the wheels, the second mechanical linkage defines a fixed overdrive speed relationship between the engine and the fraction wheels.

摘要： 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.

摘要： 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.

摘要： A system and method for controlling a step-ratio transmission gearshift during a regenerative braking event for a hybrid vehicle having an engine selectively coupled to an electric machine and an automatic transmission control transmission input torque based on a measured shift profile and a target shift profile. A torque trim term may be added to the transmission input torque or electric machine output torque in response to a difference between the measured and target shift profiles. The torque trim term may be used to modify the transmission input torque to speed the shift up or shorten the shift time if the measured shift is progressing too slowly. Likewise, the torque trim term may be used to reduce the transmission input torque or electric machine output torque if the shift is progressing too quickly relative to the target shift profile.

摘要： A vehicle includes an internal combustion engine, a driver interface having a first driver-activated selector, and a controller. The controller selectively operates the engine according to a first mode and a second mode. In the first mode the engine runs continuously. In the second mode the engine is turned off in response to a first set of operating conditions and turned on in response to a second set of operating conditions. The controller further, in response to a driver activation of the first selector, controls the engine according to the first mode and, in response to an anticipated end of a first vehicle acceleration event subsequent the driver activation of the first selector, controls the engine according to the second mode.
