Hydraulic brake system i.e. pump-less anti-lock braking sub system, for use in e.g. front wheel of motor bike, has bypass line surrounding normally open valve, and decentralized unit connected with central unit and wheel speed sensor

摘要

The system (2) has a master brake cylinder (6) connected with a brake (22) via a brake pipe (18). A normally open valve (30) is connected in the pipe. A bypass line (34) surrounds the normally open valve, and an electronic decentralized unit (60) is linked with the normally open valve and a normally closed valve (38) for controlling the normally open valve and the normally closed valve. The decentralized unit is connected with an electronic central unit (80) and a wheel speed sensor (50), and designed as a smart plug. The speed sensor is designed as a passive inductive sensor or active sensor. An independent claim is also included for a method for operating the hydraulic brake system.
