Cable puller type EPB(Electric Parking Brake) system was used for the large passenger cars and SUV for a long time. However, it also had the disadvantages such as problem of poor underbody package and difficulty of design. In order to overcome these disadvantages, a novel EPB system to replace cable puller type EPB system was proposed. First, we had changed position of EPB actuator from rear sub-frame to rear wheel because of improvement of underbody package. Second, we had integrated the actuator to rear DIH(Drum In Hat) parking brake while penetrating carrier to set the specific components of EPB system. And then, the superiorities of the developed EPB system to compare with cable puller type EPB system were verified via up and down hill hold test, working noise test and working time test etc. In addition, it could obtain the weight reduction effect of EPB system. Finally, we proposed the supply strategy for the developed EPB system to realize vehicles.

A novel EPB(electric parking brake) system to replace cable puller type EPB system was proposed. For this system, high performance EPB system integrated actuator was newly developed. The superiorities of the developed EPB system comparing with cable puller type EPB were verified via up and down hill hold test, working noise test and working time test etc. In addition, under body package will be better through these results because parking cable can be removed. Also, it could obtain the reduction effect of vehicle weight. Finally, a developed EPB system is expected to be used for large FR sedan.
