VEHICLE ELECTRONIC BRAKE SYSTEM CAPABLE OF PRECISELY CONTROLLING PRESSURE AND PROVIDING STABLE PEDAL STEPPING SENSATION AT THE TIME OF BRAKING

摘要

PURPOSE: A vehicle electronic brake system is provided to convert the rotation force of motor into the linear motion and generate the fluid pressure, thereby precisely controlling pressure and simplifying a structure.;CONSTITUTION: A vehicle electronic brake system includes a pressure supplying unit (110), a hydraulic control unit (120), cutoff valves (143,144), and a simulation device (150). The pressure supplying unit operates by receiving the volition that a user will brake from a pedal displacement sensor (11) as an electrical signal. The hydraulic control unit brakes a wheel by using force generated by the pressure supplying unit, and consists of two wheel brake circuits with a first circuit (121) and a second circuit (122). The cutoff valves control the fluid pressure that is transferred from a master cylinder (20) to a wheel cylinder (40). The simulation device provides reaction force for a brake pedal (10) by connecting with the master cylinder.;COPYRIGHT KIPO 2013
