Hybrid System and Shift Control System

System Outline

The hybrid system is a powertrain to combine and use two different kinds of power sources such as gasoline engine and electric motor. The system uses optimum power source, either the gasoline engine or electric motor to fit the driving condition best and maximizes each one's strengths while compensating for each other's shortcomings. Thus, the driving performance with seamless response is attained and the fuel consumption and gas emission are reduced significantly at the same time.
