    • An apparatus is provided for a vehicle having components of a parking brake system and components of a service brake system. The apparatus comprises a normally-energized solenoid operatively coupled to components of the parking brake system and for, when de-energized, exhausting air pressure in at least some components of the parking brake system to set park brakes. The apparatus further comprises an electronic controller arranged to (i) monitor a combination of one or more signals indicative of a service brakes holding function, (ii) monitor a combination of one or more signals indicative of a fault condition, and (iii) provide one or more signals to de-energize the normally-energized solenoid to exhaust air pressure in at least some components of the parking brake system and thereby to set park brakes when both signals indicative of a service brakes holding function and signals indicative of a fault condition of the vehicle are detected.
    • 提供了一种用于具有驻车制动系统和行车制动系统的部件的部件的车辆的装置。 该装置包括可操作地联接到驻车制动系统的部件的正常通电螺线管,并且当在停车时,在驻车制动系统的至少一些部件中排出空气压力以设定驻车制动器。 该装置还包括电子控制器,其被布置为(i)监视指示维修制动器保持功能的一个或多个信号的组合,(ii)监视指示故障状况的一个或多个信号的组合,以及(iii)提供 一个或多个信号,以使通常的通电螺线管断电,以排放驻车制动系统的至少一些部件中的空气压力,从而当指示行车制动器保持功能的两个信号和指示故障状态的信号时,设定驻车制动器 的车辆。
