<p><P>PROBLEM TO BE SOLVED: To obtain a good operation feeling corresponding to the operation speed of a brake pedal, and to reliably carry out braking of a vehicle at a fault of a brake pedal operation amount detecting device and the like. <P>SOLUTION: In the vehicular brake hydraulic pressure control device comprising the brake pedal 1, the brake pedal operation amount detecting device 22, a master cylinder 6 generating hydraulic pressure, a wheel brake, and a brake hydraulic pressure controlling portion 5, a hydraulic pressure control chamber, a solenoid valve capable of switching first control and second control, and an electric motor 23 are provided. To the electric motor 23, an operation feeling generating circuit 25 composed of a resistance (R) 27, a capacitor (C) 30, and a coil (L) 28 is connected, at the time of the first control. By rotating the electric motor 23, reaction force feeling is given to the operation feeling. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
