The invention relates to leak detection of a pneumatic brake system, in particular to a leak detection system for a pneumatic brake system of a vehicle. The pneumatic brake system has a control unit, a pneumatic circuit, and an air tank configured to supply pneumatic pressure to the pneumatic circuit. The pneumatic circuit has a plurality of valves configured to be individually controlled by the control unit. The leak detection system includes program code configured to, when executed by the processor, individually control the valves of the pneumatic circuit so as to isolate sub-circuits of the pneumatic circuit. The leak detection module is configured to monitor a pressure in the pneumatic circuit to detect a leak, where the leak detection module detects a leak in the sub-circuit if the pressure decreases with the sub-circuit isolated.
本公开涉及气动制动系统的泄漏检测,特别地涉及一种用于车辆的气动制动系统的泄漏检测系统。所述气动制动系统具有控制单元、气动回路以及被构造用以向气动回路供应气动压力的空气罐。气动回路具有被构造成由控制单元单独控制的多个阀。泄漏检测系统包括程序代码,该程序代码被配置成当由处理器执行时单独地控制气动回路的这些阀以便隔离气动回路的子回路。泄漏检测模块被配置用以监测气动回路中的压力以检测泄漏,其中如果在子回路被隔离的情况下所述压力降低,则泄漏检测模块检测到子回路中的泄漏。
