摘要： The invention relates to a method for detection and reduction of the negative consequences of a leak in a pneumatic brake line (28, 30) of an electropneumatic brake device (1) having an ABS control, which has ABS pressure control valves (32, 34) in the brake lines (28, 30) and a pressure sensor in a pressure control module (4). According to the invention, the leak is detected by measuring the actual brake pressure by means of the pressure sensor and switching the ABS pressure control valves (32, 34), and the consequences of said leak are reduced by blocking the brake line affected by the leak (28, 30) by means of the associated ABS pressure control valve (32, 34).

摘要： A vehicle safety device (200) for preventing an unoccupied vehicle moving uncontrollably. The device comprises a control module (201) and a brake module (203). The device (200) is configured to detect when a driver leaves said vehicle. The device (200) is also configured to activate, through the brake module (203), a braking system when the device detects that said driver has left the vehicle. The device may improve the safety of a vehicle in which it is fitted. A system (300) comprising the device (200) and a vehicle (400) comprising the system (300) are also described. A method of preventing an unoccupied vehicle moving is also described. The device, system, vehicle and method are particularly useful for preventing accidents in large commercial vehicles caused by a driver leaving the vehicle without engaging a parking brake.

摘要： The invention relates to an assembly comprising a detection module which is provided with an integrated measuring transducer and a plurality of detectors connected or connectable thereto. The inventive measuring transducer is used for processing/converting a plurality of signals of analog detectors. Said measuring transducer is also connected to a control device (8) separated therefrom by means of an intermediate bus (14). Said control device performs an action on the measuring transducer operation and/or predetermines said operation.

摘要： A vehicle includes a brake pedal, a master cylinder, a braking circuit with a wheel cylinder, and a brake pressure generator with strokable piston. A pedal feel simulator is coupled to the master cylinder through a switchable valve, the simulator providing a reaction force. An isolation valve closes to isolate the braking circuit from the master cylinder and the simulator circuit. A controller is programmed to connect the simulator circuit with an outlet of the brake pressure generator, and to stroke and retract the piston at a designated diagnostic time. The controller observes a pressure decrease as the piston retracts and checks whether the pressure-decrease to piston-retraction relationship is within a predetermined acceptable range for continued operation of a brake-by-wire mode in which the master cylinder is coupled to the simulator circuit and decoupled from the braking circuit.

摘要： Disclosed is an electrohydraulic pressure regulating device (30) with integrated pressure sensors (16) for detecting the pressure of a fluid in pressure lines (34), wherein several pressure measuring transducers are arranged in a cavity (10), each measuring transducer consisting of a pressure measuring membrane (32) and an electrically passive measuring transducer (33). The measuring transducer does not include a device for calibrating the electric transducer signal. The invention also relates to a method for compensating errors, wherein error-corrected pressure characteristic variables are calculated from the pressure characteristic variables of the pressure sensors by means of a digital allocation specification.
