Hyundai Develops World’s First Active Transmission Technology for Hybrid Cars

 

The new innovation will be applied to the brand’s impending Sonata hybrid and other hybrid models, the company reported in a statement.

 

The ASC technology uses new control logic software to the hybrid control unit in reducing gear shift time by 30 percent, which helps the vehicle`s acceleration performance, fuel economy and the reliability of the gear box. Therefore, the new Sonata hybrid shows an improvement of over 10 percent compared to its previous model and a faster 0-100km/h time by 0.2 seconds.

 

The new technology incorporates precise motor control to automatic transmission. Conventional hybrid cars don't have torque converters in order to augment fuel economy as torque converters lose energy during the process of transmission, but this system requires longer shift times or causes transmission impact. Most of these drawbacks can be addressed by the ASC technology as it allows the hybrid’s electric motor to take control of gear shifts with software logic alone, Hyundai Motor Group said. Hyundai Motor Group has registered a total of 20 patents for the technology in the U.S., Europe and China.
