Abstract
A method operates a braking device for motor vehicles, in particular for utility vehicles. Along a trailer supply line for supplying air to a parking brake of a trailer and/or a trailer control line for supplying air to an operating brake of a trailer, the air pressure is measured by at least one pressure transducer and is transmitted in the form of an electric signal to an electronic control unit of the motor vehicle. In the event of a faulty pressure change response, an open trailer supply line and/or an open trailer control line is detected.

A method for operating a braking device for a motor vehicle, comprising:
- along a trailer supply line for aerating a parking brake of a trailer and/or along a trailer control line for aerating a service brake of a trailer, measuring air pressure by way of at least one first pressure transducer;
- and
- transmitting the measured air pressure, in the form of an electrical signal, to an electronic control unit of the motor vehicle, so that in case of a faulty pressure change behavior, an open trailer supply line and/or an open trailer control line is detected.
A braking device for a motor vehicle, comprising:
- at least one compressed air fitting;
- an electronic control unit;
- at least one input element;
- at least one first switching valve;
- at least one first pressure transducer;
- and
- a first trailer coupling unit and a second trailer coupling unit, wherein
- the electronic control unit is connected to the input element, a control input of the first switching valve, and the first pressure transducer,
- a trailer supply line is provided such that an output of the first switching valve is connected to the first trailer coupling unit,
- a trailer control line is provided, and
- the first pressure transducer is connected to the trailer supply line and/or the trailer control line.
