Component

GDU
GDUGear Drive Unit
The GDU (electric vehicles reducer) controls the motor's rotational speed according to the vehicle's driving strategy, converting it into optimal torque. HYUNDAI TRANSYS offers a wide lineup of reducers suitable for small, large, and high-performance vehicles. Through gear profile optimization, it enhances power transmission efficiency and reduces noise.
I-DAS
I-DASIntegrated Disconnect Actuator System
HYUNDAI TRANSYS' world-first disconnect system for electric vehicles (DAS) is a device that can connect or disconnect the motor and drive shaft depending on the driving situation, and can freely switch between 2WD and 4WD. DAS reduces unnecessary power loss and increases power efficiency, contributing to improved mileage of electric vehicles.

Software

HYUNDAI TRANSYS uses the AUTOSAR platform to configure the inverter software. In order to develop inverters with excellent performance and efficiency, the company is developing inverter software in consideration of various environmental factors. In addition, it has excellent support/response capabilities such as high-speed CAN/CAN-FD support, diagnostic function, cyber response, and calibration through XCP.
