Hyundai’s new e-Corner technology allows all wheels to turn 90 degrees

Hyundai Mobis has released a demo car with their innovative e-Corner System, that could completely change driving as we know it. All four wheels may spin 90 degrees thanks to the e-Corner System technology, enabling a car to parallel park in a very limited space. The module can also rotate the front wheels inside and the rear wheels outside to conduct 360-degree idle turns and 180-degree retreats from dead ends. Hyundai Mobis’s e-Corner System is a revolutionary technology that has never been mass-produced anywhere in the world. This system is seen as a critical mobility technology for electrification and self-driving.

In a demonstration video, the demo car equipped with this system was seen driving through the Hyundai Mobis Proving Ground in Seosan and on nearby roads to show off various driving techniques. This technology was previously considered part of the future, so seeing the demo car traveling on actual roads was pretty interesting. According to Hyundai Mobis’ head of FTCI, Cheon Jae-seung, the firm is perfecting the e-Corner System to fulfill the demands of future transportation. To advance as a mobility platform supplier, the business will obtain specialized mobility solutions that can be used in autonomous driving and Purpose Built Vehicles (PBVs).

The e-Corner System is an all-in-one package module that is mounted on each wheel and enables some incredible moves that are impossible in a standard car. It enables parallel parking in confined places without backing up or turning the steering wheel, as well as crab driving, in which all four wheels pivot perpendicular to the curb. By rotating all four wheels in the same direction at a 45-degree angle, the e-Corner System also enables diagonal driving, which makes it easier to avoid obstacles or other cars on the road. Additionally, the pivot turn allows the driver to rotate the vehicle at any point on the central axis.

The module integrates the steering, braking, and suspension requirements of a wheel into a standalone unit that is coupled to an in-wheel motor at the corner of a vehicle. In ordinary use, a car outfitted with four e-Corner modules would look and operate identically like a conventional EV, but all of its driving functions are by-wire, with a central ECU making sure the modules communicate with one another. The system’s magic has been shown on a Hyundai Ioniq 5 on public roads near the corporate campus. The degree of rotation made possible by eliminating linkages like half-shafts and steering racks is what makes it unique.
