Description

Hybrid Power Train for Vehicle The present invention relates to a hybrid powertrain structure of a vehicle. A vehicle's hybrid powertrain is configured to drive the vehicle by utilizing both power generated from an internal combustion engine and power generated from an electric motor. The powertrain of the hybrid vehicle described above is designed to improve driving efficiency by utilizing the torque characteristics of the engine and the motor in a complementary manner; it is desirable to be able to implement many driving modes and gear ratios while minimizing the weight, volume, and cost of the powertrain. The matters described as the background technology of the above invention are intended only to enhance understanding of the background of the invention and should not be construed as an acknowledgment that they constitute prior art already known to those skilled in the art.
