Since we’re in this energy transition phase, crab walk in EVs is probably gonna become as normal as a reverse gear in the future. The latest one to crab walk is the Hyundai Ioniq 5. Well, it’s not the same Ioniq 5 you might find in your local Hyundai dealership, but a specially modified one by Hyundai Mobis, the automotive technology and R&D company of the Hyundai Motor Group.
Besides crab walk (or Crab Driving in Hyundai Mobis’ terms), the company’s so-called e-Corner System also demonstrates Pivot Turn and Zero Turn.
The Crab Driving is fairly self-explanatory. The entire wheel assembly including the suspension rotates 90-degrees, at all four corners of the vehicle, enabling the driver to simply slide into a parallel parking spot. The Pivot Turn is also I think fairly self-explanatory; the rear wheels rotate 90-degrees, enabling the driver easy perpendicular parking. I assume the angle of this rotation can be controlled as per the parking spot available: a full perpendicular or an angled one as shown in the second picture above.
The Zero Turn might not be self-explanatory, but it performs a 360-degree turn; useful in super tight spaces. But do note that it is not the same as Rivian’s Tank Turn and EQG’s G-Turn. All four wheels rotate at an angle here to achieve this turn, as opposed to what Rivian and Mercedes do. In simple terms, the tyres won’t get destroyed here. The video below also demonstrates Diagonal Driving.
The e-Corner System developed by Hyundai Mobis is an all-in-one package module of brake-by-wire, steer-by-wire, damper, and in-wheel motor, installed on each wheel, the company said.
We are idealizing the e-Corner System in order to meet the demands for future mobility. We will secure different types of customized mobility solutions that can be applied in autonomous driving and PBVs to solidify our vision of reaching new heights as a mobility platform provider. – Cheon Jae-seung, Head of FTCI (Future Technology Convergence Institute), Hyundai Mobis.
