Abstract

See full text

A hydraulic brake system is configured such that a pressure of a working fluid from a high-pressure-source device is adjusted by electromagnetic pressure-increase and pressure-decrease linear valves and such that a brake device generates a braking force having a magnitude that depends on the pressure adjusted by the linear valves, wherein the following controls are selectively executable, as a control of the energizing currents supplied to the linear valves, a feedback control based on a difference between an actual braking-force index and a target braking-force index; and a feedforward control based on the target braking-force index executed by placing each valve in a valve equilibrium state, wherein, in the feedforward control, an energizing current is supplied to at least one of the two linear valves, the energizing current being larger than that according to a preset relationship between a braking-force index and an energizing current in the valve equilibrium state.
