Abstract
A vehicle brake system, capable of realizing a brake-by-wire construction which can be installed in vehicles in the same manner as conventional brake systems, is provided with a booster device, a master cylinder, wheel brakes, and a hydraulic pressure control device interposed between the master cylinder and the wheel brakes. The system is further provided with a stroke sensor for detecting the moving stroke of a brake pedal, a simulator for applying to the brake pedal a pseudo reaction force corresponding to the moving stroke of the brake pedal, a play or idling component arranged between the booster device and the hydraulic pressure control device for absorbing the moving stroke of the brake pedal by a predetermined amount, and an electronic control device for controlling the hydraulic pressure control device based on an input from the stroke sensor.
