Abstract
A split-axis transmission hybrid system may include two planetary gear sets to provide two parallel torque paths from an input axis to an output axis. A secondary power source may be coupled to either the input axis or the output axis to provide torque to the system. Thus, the split-axis transmission hybrid system may provide the ratio preselection capability and the low power losses of a dual-clutch transmission and the ratio-changing control and smoothness of a traditional powershift automatic transmission, while also providing the improved efficiency and enhanced drivability of a hybrid power source arrangement.
