Hyundai Mobis has successfully developed electronic-Drum In Hat (eDIH) parking brake system used for large-sized pickup trucks. The new invention is expected to dominate the market in advance as the first application of its kind.

The South Korean leading auto parts supplier said on Aug.29 it has spurred the mass production after completing the development of the eDIH system that improves the power of parking brakes customized for large pickup trucks. The e-DIH refers to a type of electronic parking brake (EPB). The EPB brake system, by operation type, is divided into a motor-on-caliper (MOC) type and an electronic drum-in-hat (eDIH) type, and the former is applied to private vehicles like sedans and SUVs.

By comparison, the drum-in-hat (DIH) means an exclusive parking brake with a drum structure. The existing mechanical system powered by cables is changed into an electronically controlling motor system, which refers to eDIH. The new system is largely applied to trucks and buses with large weight and capacity, which require more braking power. As the market scale for sedans and SUVs is much larger, eDIH is considered the blue ocean where there are no application cases, as well as a niche market in terms of electronic parking brakes.

Hyundai Mobis has the newly developed the eDIH system customized for large-sized pickup trucks in particular. Of course it can be applied to sedans, commercial vehicles and general pickup trucks. Until now, some global auto parts makers have developed the eDIH, but there is no one who has invented the system optimized for large pickup truck models. Hyundai Mobis has increased the brake force of the eDIH by1.5 times higher compared to the conventional electric park brakes (side and foot brakes), while reducing its size by 30% by developing some parts as all-in-one, contributing to cost reduction.
