A system for determining a pneumatic connection status of a trailer (200) relative to a towing vehicle (100), the system comprising: a control unit (6a) for controlling the operation of a service brake valve (2a) and/or a parking brake valve (2b); at least one acoustic sensor (4) for detecting sound and transmitting corresponding acoustic data; a processing unit (6b) in data communication with the acoustic sensor (4) to receive the acoustic data. The processing unit (6b) is configured to process the acoustic data and to determine a pneumatic connection state of the trailer (200) based at least on the acoustic data, the at least one acoustic sensor (4) being arranged at a trailer service brake control line (1a) of the towing vehicle (100), between the service brake valve (2a) and the control line coupling (30a), and/or at a trailer supply line (1b) of the towing vehicle (100), the brake device is arranged between the parking brake valve (2b) and the supply line coupling head (30b). A method for determining a pneumatic connection status of a trailer (200) with respect to a towing vehicle (100), the method comprising: receiving (501) a trigger signal, releasing (502) compressed air through a pneumatic line to produce sound, detecting (503) the sound produced by the release (502) of compressed air and converting the sound into a data signal, transmitting (504) the data signal to a processing unit (6b), and determining (505) the pneumatic connection status of the trailer (200) with respect to the towing vehicle (100). The data signal is processed (505) to produce derived data, and a pneumatic connection status of the trailer is determined (506) based at least on the derived data.

    一种用于确定拖车(200)相对于牵引车(100)的气动连接状态的系统,该系统包括:控制单元(6a),用于控制行车制动阀(2a)和/或驻车制动阀(2b)的操作;至少一个声学传感器(4),用于检测声音并且传输相应声学数据;处理单元(6b),与声学传感器(4)数据通信以接收声学数据。该处理单元(6b)配置为用于处理该声学数据并且至少基于该声学数据确定拖车(200)的气动连接状态,其中,该至少一个声学传感器(4)布置在牵引车(100)的拖车行车制动控制管线(1a)处,在行车制动阀(2a)与控制管线联接头(30a)之间,和/或在牵引车(100)的拖车供应管线(1b)处,在驻车制动阀(2b)与供应管线联接头(30b)之间。一种用于确定拖车(200)相对于牵引车(100)的气动连接状态的方法,该方法包括:接收(501)触发信号,释放(502)压缩空气通过气动管线以产生声音,检测(503)由压缩空气的释放(502)所产生的声音并且将声音转换成数据信号,传输(504)数据信号至处理单元(6b),处理(505)数据信号以产生导出数据,并且至少基于导出数据确定(506)拖车的气动连接状态。
