摘要： A hybrid transmission having an input member, an output member, and a single motor/generator is characterized by a plurality of fixed-ratio modes of operation and at least one electrically variable mode of operation. In the fixed-ratio modes of operation, the speed ratio between the input member and the output member is independent of the speed of the motor/generator. In the electrically variable mode of operation, the speed ratio between the input member and the output member is dependent upon the speed of the motor/generator.

摘要： A hybrid control system for a hybrid electric vehicle (HEV) includes a hybrid control module. The hybrid control module includes a first motor control module that controls output torque of a first motor. A second motor control module controls output torque of a second motor based on a second motor torque request signal. The second motor torque request signal is generated based on a transmission output torque request signal prior to startup of an engine of the HEV. An override module generates a torque override request signal during the startup. The first motor control module controls output torque of the first motor to crank the engine during the startup. The second motor control module adjusts output torque of the second motor based on the torque override request signal and not the transmission output torque request signal during the startup to minimize vehicle jerk during the engine start.
