09
Authorized third-party test run by Seoul National University of Science & Technology for EV2W with transmission
12
Under developing 5-speed automatic transmission with gear ratio of 352%(difference of gear ratio between gears is under 40%)
2019
03
Prototype EV2W with 5-speed automatic transmission in both front and rear wheel
07
In-house TCU(Transmission Controll Unit) developmentDevelopment shift logic and algorithms by our own technology
Independent and core powertrain (Transmission+Controller+Motor) system is
constructed.
* Sophisticated and state-of-the-art TCU is developed by in-house technology
11
Development of 6-speed automatic transmission for EVBecause initial torque of electric motor is greater than ICE, shift shock in EV is stronger than ICE’s.
That requires EV to have 6-speed at least for seamless shift and minimum gear ratio of 400%.
12
Zero Shift Time-lagFirst tech overcoming 0.2 second time lag.
Shock absorbing tech precedes “Zero Sift Time-lag”.
Synthesizing tech with hardware (transmission) and software (TCU).
Hard to duplicate
