Anti-locking brake system

摘要

An anti-locking brake system for traction control and vehicle dynamics control such that a pump for actuating a wheel brake removes brake fluid from a brake pressure generating unit and supplies it to the wheel brake. Disposed between the brake pressure generating unit and an input connection of the pump is a valve arrangement in the form of a 2-connection/3-position valve, which in a non-actuated (normal) position blocks the connection between the brake pressure generating unit and the input connection of the pump. In a first actuating position the valve arrangement establishes a secondary flow connection between the brake pressure generating unit and the input connection of the pump, and in a second actuating position establishes a primary flow connection between the brake pressure generating unit and the input connection of the pump. The primary flow connection has a larger flow cross section than the secondary flow connection.
