Every manufacturer is looking to improve its future efficiency, either through hybridisation, either through improvements to current engines. hyundai ahas a different solution.

Hyundai and Kia developed the world’s first Active Shift Control (ASC) transmission technology. The innovation optimizes transmission efficiency by monitoring gear shifts 500 times per second, precisely adjusting the transmission rotation speed to for faster shift times. The new technology will benefit upcoming Kia hybrids.

ASC applies new control logic software to the Hybrid Control Unit (HCU), which then controls the electric motor to align the rotational speeds of the engine and transmission to reduce gear shift time by 30 per cent. The technology also delivers smoother gear changes despite quicker shift times.

Conventional hybrid vehicles do not have torque converters in order to further improve fuel economy as torque converters lose energy during the process of transmission. Although fuel efficient, such a system also requires longer shift times to ensure smoother gear changes.

ASC technology allows the hybrid’s electric motor to also take control of gear shifts by applying new software logic to the Hybrid Control Unit (HCU) to mitigate issues with slower shift time. The HCU monitors the rotational speed of transmission with a sensor installed inside the electric motor at 500 times per second to quickly synchronize the rotational speed with that of engine.

With the synchronization, shift time is reduced by 30% from 500ms to 350ms. This not only improves hybrid vehicle’s acceleration performance and fuel economy, but also durability of the transmission by minimising friction during gear shift.
