The invention relates to a brake system with a fluid storage auxiliary brake module. A brake system for actuating at least one wheel brake includes a reservoir and a master cylinder operable to provide a brake signal in response to actuation of a brake pedal connected to the master cylinder. The master cylinder is selectively operable during a manual propulsion mode to generate a brake actuation pressure to the at least one output to hydraulically actuate the at least one wheel brake. The power transmission unit is configured to actuate at least one of the wheel brakes in a non-fail normal braking mode. The auxiliary brake module is configured to selectively provide hydraulic fluid to each wheel brake in an enhanced braking mode. The auxiliary brake module includes a pump motor that drives at least one pump unit. Each pump unit is operatively connected to a fluid accumulator associated with an associated wheel brake to selectively vary an amount of hydraulic fluid provided to the wheel brake.
本发明涉及具有流体存储辅助制动模块的制动系统。一种用于致动至少一个车轮制动器的制动系统包括储存器和主缸,所述主缸能操作成响应于连接到所述主缸的制动踏板的致动而提供制动信号。所述主缸在人工推进模式期间选择性地能操作成向至少一个输出端产生制动器致动压力,以液压地致动至少一个车轮制动器。动力传输单元被构造成在非故障正常制动模式下致动所述车轮制动器中的至少一个。辅助制动模块被被构造成在增强制动模式下选择性地向每个车轮制动器提供液压流体。所述辅助制动模块包括驱动至少一个泵单元的泵马达。每个泵单元操作性地连接到与相关的车轮制动器相关联的流体蓄能器,以选择性地改变提供到车轮制动器的液压流体的量。
