As the development of miniaturization for unmanned aerial vehicle, a smaller size and less weight brake control system is deeply needed. This paper presents a highly integrated brake control device, which has a huge difference from traditional Conventional Hydraulic Brake (CHB) and Electromechanical Brake (EMB) systems. The proposed design solves the limitations above by introducing the electromechanical—hydraulic hybrid (EHH) brake concept. A simulation of the brake control device is studied. According to the simulation result, a dual-redundancy pressure-feedback closed-loop control strategy is effective for the use of vehicle brake system. Experimental results show that the integrated brake control device meets the requirements of the vehicle system. It not only can help the miniaturization of the unmanned aerial vehicle, but also can realize brake-by-wire.
