摘要： An electro-hydraulic braking system of the type capable of operating in a braking-by-wire mode wherein hydraulic pressure is applied to braking devices (18a, 18b, 18c, 18d) at the vehicle wheels in proportion to the driver's braking demand as sensed electronically at a brake pedal (10), in a push-though mode wherein hydraulic pressure is applied to the braking devices (18a, 18b, 18c, 18d) at the vehicle wheels by way of a master cylinder (34) coupled mechanically to the brake pedal (10) and in an ABS mode in which the braking pressures at the individual wheels are controlled in dependence, inter ala, on the detected rotational behaviour of the vehicle wheels, and which includes a hydraulic travel simulator (38) which is connected hydraulically to the master cylinder (34) by way of an electrically controlled isolation valve (36) for providing improved feel for the driver through the brake pedal in the push-through operating mode. In order to ensure that the brake pedal cannot be pushed beyond a position corresponding to a wheel-locking pressure, and thereby make it easier for the driver to modulate the brake pressure and avoid excessive deceleration if the road adhesion improves, the travel simulator isolation valve (36) is arranged to be closed when the ABS mode is active.

摘要翻译： 一种电液式制动系统，其能够以制动制动模式操作，其中在车轮处的制动装置（18a，18b，18c，18d）上按照感测到的驾驶员的制动需求成比例地施加液压 以制动踏板（10）的方式以电动方式通过主缸（34）以制动踏板（10）的方式在液压压力施加到车轮上的制动装置（18a，18b，18c，18d） 制动踏板（10），并且在ABS模式中，各个车轮处的制动压力根据检测到的车轮的旋转行为而依赖于控制，并且包括连接的液压行驶模拟器（38） 通过电控隔离阀（36）液压地连接到主缸（34），用于通过直通式操作模式通过制动踏板提供驾驶员的改善的感觉。 为了确保制动踏板不能被推到超过与车轮锁定压力相对应的位置，从而使驾驶员更容易调节制动压力，并且如果道路附着力改善则避免过度减速，行驶模拟器隔离阀 （36）被布置为当ABS模式有效时关闭。
