ELECTRIC BOOSTER TYPE BRAKING DEVICE AND A PRESSURE OSCILLATION CONTROL METHOD CAPABLE OF PROTECTING A MOTOR AND A SOLENOID VALVE FROM A PRESS OSCILLATION

摘要

PURPOSE: An electric booster type braking device and a pressure oscillation control method are provided to improve the lifetime of a motor and a component by preventing the damage of a motor through the installation of a solenoid valve.;CONSTITUTION: An electric booster type braking device comprises a braking pressure generating portion. The braking pressure generating portion forms the braking pressure of front wheel and rear wheel through the pressing of a main master cylinder using an electric booster(4) which is controlled with ECU(1) according to the stroke of a pedal(2). The braking pressure generating portion supplies the braking pressure to a pedal simulator(30) which forms a reaction force for stepping force within the load of the electric booster. The braking pressure generating portion has a pair of hydraulic lines which comprises an ESC distributing the braking pressure from a main master cylinder to a wheel cylinder.;COPYRIGHT KIPO 2012
