Fuzzy Adaptive Autonomous Electromagnetic 2-Speed Gearbox for Electric Vehicle

The Global Automotive Policy (GAP) objective is the development of advanced automotive
technologies related to MobilityasaService,
Next Generation Vehicle (NxGV) and Industrial
Revolution (IR) 4.0. NxGVs can be electric vehicles (EV) and electrical conditional automation
vehicles (EAV). Technologies prototyping for NxGV with increasing levels of automation will be the
clear mobility of the future. The NxGV transmission could be either an automatic transmission (AT) or
a continuously variable transmission (CVT). However, the automatic gearbox and CVT are heavier
and require more space, therefore they consume more energy and are difficult to install with an NxGV
electric motor. In addition, the singlespeed
gearbox (SSGB) is lighter, but not suitable for delivering
enough torque in climbing. Therefore, developing a compact and automatic energy efficient
transmission is a key technology challenge for NxGV. The purpose of this study is to present a
prototype of a compact and lightweight artificial adaptive fuzzy interference system (AAFIS)
electromagnetic two speed
gearbox (AEM2SGB) for the NxGV in accordance with the GAP 2020
and IR4.0 forward policy. Research Management Centre (RMC), International Islamic University
Malaysia with a research grant “Research Incentive Flagship Grant (Ref. RIF190320032),
financed
this project. The AEM2SGB
was developed for a 3.0 kN IIUM test car using equivalent road loads
and found the AEM2SGB's shift times in first gear to be 1.5 seconds with a higher torque of 530 Nm
and 1.8 seconds in second gear for 110 km / h. The highend
AEM2SGB is therefore expected to
reduce the weight of the NxGV drivetrain by about 46% and improve the performance of the NxGV by
reducing power consumption by about 30% and extending the range by 15%. AAFIS capabilities for
successful management of AEM2SGB can operate in NxGV automatic mode.
