Hyundai Motor Group has evolved how it’s calling the planet’s first Active Shift Control transmission for hybrid powertrains. It will eventually debut inside the all-new Sonata arriving later in 2010.
The technology promises optimised transmission efficiency as it is able to monitor gear shifts 500 times per second, and might adjust the rotation speed from the transmission for faster shift times. This is often due to a whole new control keeper which controls the electrical motor on the hybrid system to align rotational speeds.
Hyundai explains that conventional hybrids avoid using a torque converter, like the majority of petrol and diesel cars, as converters lose energy with the way they operate. Included in the mechanism of the way torque converters work, gear shift times are often longer to be certain smoother shifting. For the new ASC technology, Hyundai explains:
“ASC technology permits the hybrid’s motor unit also to manage gear shifts by employing new software logic on the Hybrid Control Unit (HCU) to mitigate difficulties with slower shift time. The HCU monitors the rotational speed of transmission having a sensor installed inside motor unit at 500 times per second to quickly synchronise the rotational speed start of engine.”
As the result, the company says shift times are reduced by 30 %, improving performance and gas mileage. The durability on the transmission is improved, Hyundai says, as there is less friction during shifts.
The new technology will debut together with the 2020 Hyundai Sonata Hybrid, and definately will roll out in other Hyundai and Kia hybrids later on.
