Patent ID: 7891746

Claim:
A braking device for a motorcycle, comprising: a master cylinder interlocked with a brake operating portion; wheel braking means for imparting a braking force to a wheel with use of hydraulic pressure in the master cylinder; a brake passage for connecting the master cylinder with the wheel braking means; a hydraulic modulator for supplying a hydraulic pressure generated by an electric actuator to the wheel braking means through the brake passage; and a first electromagnetic opening/closing valve V 1 of a normally open type disposed on the master cylinder side with respect to a connection of the brake passage with the hydraulic modulator; wherein, when applying the brake, the electric actuator is controlled in accordance with the amount of operation of the brake operating portion in a closed state of the first electromagnetic opening/closing valve V 1 to supply a hydraulic pressure to the wheel braking means through the hydraulic modulator, and wherein the first electromagnetic opening/closing valve V 1 is open when a main power supply is turned ON or until a vehicle speed reaches a predetermined vehicle speed, and after arrival of the vehicle speed at the predetermined vehicle speed, a rated electric current is supplied to the first electromagnetic opening/closing valve V 1 to close the valve, thereafter, the electric current supplied to the first electromagnetic opening/closing valve V 1 is decreased within a predetermined range that is able to maintain this state of operation, wherein the first electromagnetic opening/closing valve V 1 is interposed in the brake passage, and a first section of the brake passage extends between and directly connects to an input side of the valve V 1 to the master cylinder, and a second section of the brake passage extends between and directly connects to an output side of the valve V 1 to the wheel braking means.
