Hyundai Mobis Develops Cutting-Edge Braking and Parking Technologies

Hyundai Mobis has announced that it has developed really innovative parking and braking technologies called the iMEB (integrated MOBIS Electronic Brake) and RSPA (Remote Smart Parking Assist) respectively at its Cheonan plant and Jincheon plants in Korea. The company has now transformed intself from a latecomer to one of the global leaders when it comes to braking and parking assist technologies. Hyundai Mobis focused its research efforts on technologies that are most suitable for the age of electronic and autonomous driving, and has now succeeded in developing a range of technologies that are as advanced or even more advanced than that of its global competitors.

For iMEB and RSPA, Hyundai Mobis used a ‘jump-up’ strategy, as part of which it acquired the technologies from the design phase rather than playing ‘catch-up’ by keeping tabs on the technologies of competitors and coming up with similar technologies. Whicle the company’s competitors worked on commercializing separate (hydraulic/electronic) regenerative brake systems and fully-automated parking systems, for the purpose of automating steering, acceleration and deceleration and transmission, the technologies developed by Hyundai Mobis are definitely a cut above.

Hyundai Mobis has already successfully supplied iMEB and RSPA technologies for EVs and will now expand the supply to internal-combustion vehicles. The company will also strive to start mass production and try to secure overseas contracts.

● iMEB (integrated MOBIS Electronic Brake)
A regenerative brake system is used in environment-friendly cars, for recouping the energy lost through braking as electricity with a motor in order to charge the batteries. This technology reduces energy loss by 70 per cent when compared to internal combustion cars and helps to increase the fuel efficiency of hybrid vehicles by 40 per cent.
iMEB is the most advanced type of a regenerative brake system, both in terms of apparatus and software. The company first worked on the development of a hydraulic fill brake pressure supply unit in the form of an electronic motor-based system and then integrated the brake pressure supply unit and the brake control unit comprising over 30 cutting-edge control functions, like Electronic Stability Control (ESC) into a single system.

In addition to ADAS functionality, including FCA (Front Collision Avoidance) and ASCC (Advanced Smart Cruise Control), the brake control unit also contains EPB (Electronic Parking Brake).

The iMEB technology increases brake responsiveness by 13 per cent and reduces weight by 5 per cent when compared to other similar technologies. This also reduces cost by 30 per cent when compared to conventional separate hydraulic fill systems. The outcome is a shorter emergency braking distance which increases fuel efficiency, safety, downsizing of auto components and reduces the cost of cars.

During the development of iMEB, Hyundai Mobis applied for a total of 109 patents, including 20 overseas ones.
● RSPA (Remote Smart Parking Assist)

RSPA automates transmission, handling and acceleration and deceleration required for parking and unparking combined with remote control functionality using a smart key. Parking becomes easy as the technology uses 12 front and side ultrasound sensors to investigate a potential parking space, and the driver just needs a smart key to allow the car to park itself, either when inside or outside the car. It is also possible to unpark the vehicle via a remote control.

RSPA offers best-in-industry parking space awareness rate and parking sensory acuity. Both when it comes to parallel and perpendicular parking, the rate of perceiving a parking space about 30 per cent higher than that of competitors. The steering perception in remote automated parking is less different compared to manual steering.

For safety reasons, the remote automated parking system requires a driver to remote control automated parking within 4 meters of the car. The automated valet parking is a technology that uses communications between the vehicle and the infrastructure of buildings or facilities to enable the vehicle to park or unpark itself.
