Beschreibung
Zusammenfassung:	A vehicle braking system (10) includes a brake pedal (28), a master cylinder (24), first and second braking circuits each with a wheel cylinder (WC), a brake pressure generator (60) for brake-by-wirebraking, and a pedal feel simulator (80). In response to detecting impending wheel lock-up (ABS), a controller (20) conducts an anti- lock braking routine during which the controller (20) is programmed to create an artificial haptic feedback pulse to the brake pedal (28) by opening a second normally-open isolation valve (522) between the master cylinder (24) and the second brake circuit to move asecond master cylinder piston (262) until a second compensation port (322) opens. 一种车辆制动系统（10），包括制动踏板（28）、主缸（24）、各自具有轮缸（WC）的第一和第二制动回路、用于线控制动的制动的制动压力发生器（60）和踏板感觉模拟器（80）。响应于检测到即将发生的车轮抱死（ABS），控制器（20）执行防抱死制动例程，在该例程期间，控制器（20）被编程为通过如下方式来向制动踏板（28）产生人工触觉反馈脉冲：打开主缸（24）和第二制动回路之间的第二常开隔离阀（522）以移动第二主缸活塞（262），直到第二补偿端口（322）打开。
