Hyundai Mobis has announced developing an in-wheel system that lets the motor control each wheel directly. The key technologies, including the drive motor and controller, have been developed in-house, with Hyundai Mobis verifying the system’s reliability for mass-production based on IONIQ 5 with Hyundai Motor Company. The in-wheel system is seen as a technology that needs to overcome challenges, including securing drive performance and durability.
The in-wheel system offers enhanced drive and power efficiency, a longer cruising range, improved driving performance, and unique steer modes. There is no need to install a separate power transmission component, such as a drive shaft, which also enhances power efficiency. The system provides efficient torque distribution for each motor in a wheel, enabling optimum turns and body control. The in-wheel system also offers unique features like crab walking and zero turns.
Hyundai Mobis is also developing the e-Corner system, an integrated solution that combines electronic steering, braking, and suspension technologies centred around the in-wheel motor, with a goal of completing the development within the next five years. The company plans to complete the technology development to ready themselves for the future of mobility and begin mass-production of the in-wheel system by the end of this year.
