Abstract
A vehicle brake control unit includes a cylinder body (2); a spool member (18) which is slidably provided in the cylinder body (2), and has one end portion confronted with a pressure chamber (10) and the other end portion confronted with a regulator pressure chamber (24) in the cylinder body, the spool member being axially moved by both the pressure in the pressure chamber and the pressure in the regulator pressure chamber, thus adjusting the pressure of a pressure source (26) which is applied to a regulator port (2a) formed in the cylinder body. The pressure provided at the regulator port is led into the regulator pressure chamber and supplied to the wheel cylinders (33, 34, 35 and 36). The vehicle brake control unit further includes emergency-braking-operation detecting unit (65) for detecting an emergency braking operation, and brake pressure change-over unit (62, or 66 and 68) for communicating the pressure source with the wheel cylinders when the emergency-braking-operation detecting unit detects an emergency braking operation.
