Bbw brake device

Abstract

A brake fluid pressure electrically generated by a slave cylinder () in accordance with an operation amount by a brake pedal () is supplied via a VSA system () to wheel cylinders () provided respectively for wheels. This enables smooth braking by the wheel cylinders () by using a brake fluid pressure pressurized by the slave cylinder () and including little pulsation. When the VSA system () is to individually control the brake fluid pressures supplied respectively to the wheel cylinders () to control vehicle behavior, the slave cylinder () generates a brake fluid pressure corresponding to a total of the brake fluid pressures required for the wheel cylinders (). This configuration allows the slave cylinder () to generate a brake fluid pressure in just proportion.
