Hyundai Mobis invents electronic parking brake for pickup trucks

By Jhoo Dong-chan

Hyundai Mobis has invented a new electronic drum-in-hat (eDIH) parking and brake system customized for large-size pickup trucks, a company official said Monday.

According to an official, the nation’s leading auto parts supplier has completed the development of the eDIH system, and is preparing for its mass production for business operations.

Among two types of typical electronic parking brake systems that hold a vehicle and prevent it from rolling on tilted ground, the eDIH brake system is used for mostly for commercial vehicles, such as trucks and buses, while caliper-integrated system is featured on private vehicles like sedans and SUVs.

The auto supplier’s newly developed parking and brake system, the eDIH, can produce 1.5 times higher braking forces while reducing its size by 30 percent compared to conventional parking and brake system.

The official said that Hyundai Mobis’ new parking and brake system will contribute greatly to sales in the North American market, where a total of 3.8 million pickup trucks are sold every year, according to market researcher IHS. Of them, 20 percent, or some 760,000 trucks, can mount the eDIH system.

Hyundai Mobis supplies parking and brake system parts as well as various other auto parts, including chassis and lamp modules, to U.S. auto makers. It also operates two chassis production plants there.
