  • Vehicular brake system for performing effective brake operations
    Patent number: 6193331
    Abstract: A first fluid line couples first and second wheel cylinders. A second fluid line couples third and fourth wheel cylinders. A first pressure increasing unit increases pressure applied to the first and second wheel cylinders to a second pressure level which is greater than a first pressure generated by a master cylinder. When the first pressure increasing unit is in operation, a pressure difference setting unit sets a difference between pressure applied to the first and second wheel cylinders and pressure applied to the third and fourth wheel cylinders.
    Type: Grant
    Filed: December 30, 1999
    Date of Patent: February 27, 2001
    Assignee: Denso Corporation
    Inventors: Syuichi Yonemura, Youichi Abe, Mamoru Sawada
