摘要： A circuit configuration for an anti-lock brake system, which receives input from wheel sensors positioned on the driven wheels, comprises a monitoring circuit (7) which triggers a test cycle (duration T.sub.Test) when the two wheels of a driven axle signal instability for more than a predefined time span (T) during a control cycle. By way of the test cycle, braking pressure is introduced into the wheel brake of the instantaneously slower wheel (v.sub.1, v.sub.min -wheel) of the driven axle and the reaction of the driven wheels to the braking pressure delivered is assessed.

摘要： In a hydraulic brake system with anti-lock control, noise is reduced during ABS control by controlling the flow rate of high-pressure fluid from the master brake cylinder (2) to the wheel brakes (15, 16). This is accomplished by placing an analog or pulse-width modulated NO valve (40) in the brake line between the connection of the pressure side of the hydraulic pump (35) and the inlet valve (20,27) to the wheel brake. By this means, only one analog or analogized valve is needed per brake circuit as opposed to two if the inlet valves were analog valves. In brake systems with traction control or electronic stability control, a shut-off valve is already present in this location. Thus replacing the existing valve with an analog or quasi-analog valve is easy. In substitution for the non-return valve usually arranged in parallel to the shut-off valve, the shut-off valve will be electronically opened when a pressure sensor (41) detects a situation in which the fluid path from the master brake cylinder (2) to the inlet valve (20.27) needs to be unrestricted.
摘要翻译：在具有防抱死控制的液压制动系统中，通过控制从主制动缸（2）到车轮制动器（15,16）的高压流体的流量，在ABS控制期间噪声降低。这是通过将模拟或脉冲宽度调制的NO（40）放置在液压泵（35）的压力侧与进气阀（20,27）的连接处与制动器之间的制动管路中来实现的。通过这种方式，每个制动回路只需要一个模拟或者类似的阀门，而如果进气阀是模拟阀门则只需要两个。在具有牵引力控制或电子稳定控制的制动系统中，该位置已经存在截止阀。因此，用模拟或准模拟阀更换现有阀很容易。代替通常与截止阀平行布置的止回阀，当压力传感器（41）检测到来自主制动缸（2）的流体路径的情况时，截止阀将被电子地打开）到入口阀（20.27）需要不受限制。
