Embodiment Construction
[0016] figure 1 A powersplit hybrid electric vehicle powertrain capable of implementing the improved control system of the present invention is shown in schematic form. figure 1 Transaxle 10 is shown including two electric machines (generator 12 and electric motor 14 ) along with engine 16 . The planetary gear unit 18 provides a mechanically split power transfer path from the engine to the torque transfer gear arrangement that transfers drive torque to the axle and differential assemblies for the vehicle's traction wheels as shown at 22 . Provides a coordinated vehicle control system that manages the distribution of power from each power source to the traction wheels. This coordination requires a control algorithm to perform a balance of power, speed, and torque from the two power sources.
[0017] The control system includes a controller for the engine 16, a transmission control module (TCM), a high voltage battery and a battery control module (BCM), and a regenerative brak...
