Technologies for electronic control systems in automobiles are continuously being developed along with the ceaseless advancements in automobile technologies. Although the performances of automobiles have improved significantly through the advancement of the electronic control system, there is no noticeable reduction in car accidents. Approximately 94 % of such car accidents occur as a result of the mistakes made by the drivers. Research on driver assistant systems is being carried out in order to prevent such accidents in advance. These driver assistance systems include various braking system related devices, such as devices designed to prevent rolling on inclined surfaces, emergency braking device, etc. The braking system is therefore used not only in the brakes of the automobile, but also in a wide range of safety devices, such as the ABS and position control. This study carried out research on controlling the braking power by using the DC motor and solenoid value in order to change the existing mechanical braking system into an electronic braking system. The control system for the braking power of a brake is composed of the DC motor, AC motor, hydraulic pump, solenoid valve, pressure sensor, rotary encoder, and control board. |
