摘要： A digital train brake testing and train preparation assistant uses a system, method, and computer program for determining a component parameter of a train. The system may include sensor nodes mounted to a respective part of the train, wherein the sensor nodes form a sensor network on a rail car, wherein railcars form a wireless mesh network, and wherein each of the sensor nodes is configured to collect data of the component of the respective part of the train and to publish the collected data into the wireless mesh network. The system may further include a server system configured to receive the published data of the wireless mesh network and to determine the component parameter of the train based on the received data. Furthermore, a user device for displaying a component parameter determined by a system, method, and computer program for determining a component parameter of a train is provided.

摘要： A Hydraulic braking system is for braking a vehicle wheel according to a braking pressure control that includes a hydraulic pump driven by an electric motor for hydraulic pressure generation, an electronic control unit for the determination of at least one control error, based on a measured actual braking pressure compared with a pressure demand setpoint, which controls at least one actuator for a pressure increase and/or a pressure reduction of the actual braking pressure to adjust to the pressure demand setpoint. Furthermore, a method is provided for braking a vehicle wheel according to this braking pressure control and a related computer program product.

摘要： A control device and a method controlling an emergency braking pressure of a vehicle, and a vehicle having a control device of this kind, wherein a pilot control pressure (VSDI) is modulated with a pressure modulator as a function of a load condition of the vehicle, a deceleration, a speed and/or a coefficient of friction, and a safety pilot control pressure (SVSD) is controlled with an adjusting device, and wherein in normal operation, a supply pressure is controlled only by the VSDI while, in the event of a system malfunction, the supply pressure is controlled only by the SVSD, wherein it is ensured that the emergency braking pressure does not exceed a nominal pressure in the event of the system malfunction.

摘要： A method for improving the adhesion of a rail vehicle by conditioning selected axle(s), detects whether a higher total brake force can be achieved by changing the manipulated variable of the wheel slip at at least one unit from a current starting wheel slip to a forced wheel slip, and, if so, changes the wheel slip at at least one unit from the current starting wheel slip to the forced wheel slip by regulating the manipulated variable of the brake application force at the unit, whereby the friction ratios between the wheel and the rail changes at the subsequent units, and regulates the manipulated variable of the brake application force at the subsequent units to regulate the wheel slip, which is likewise changed by the changed friction ratios, at the units back to the unchanged manipulated variable of the starting wheel slip, optimized brake forces being produced at the units.

摘要： A monitoring and measuring device for an air supply system of a vehicle, in particular a rail vehicle, includes a compressor which is designed to provide compressed air; a defined volume which is situated downstream of the compressor; a shut-off valve which is situated downstream of the defined volume; a pressure sensor which is provided at any desired position on the pressure line between the compressor and the shut-off valve and is configured to measure the pressure that builds in the defined volume. A first or second air drying device, for example, is used as the defined volume. The pressure curve measured by the pressure sensor can indicate whether there is a fault or a leak. A method for monitoring and for measuring parameters of an air supply system of a vehicle, in particular a rail vehicle is also provided.

摘要： The invention relates to an axle-mounted brake disk for a rail vehicle, comprising two friction rings which are arranged in parallel and at a distance from each other and are interconnected by a plurality of ribs extending in the direction of the rotational axis of the friction rings, where at least some of the ribs are embodied with different cross-sections from each other, where the cross-sections of a first subset of the ribs, embodied as supporting elements transmitting pressure forces, do not fall below a minimum cross-section, defined by the stability required in relation to the mechanical load during a brake process, and the cross-section of a second subset of the ribs, used to radiate thermal energy, falls below the minimum cross-section.

摘要： A method and a control device determine a position-related braking ability of a vehicle. A first vehicle determines at least one piece of position-related information of a route section, the at least one piece of position-related information of the route section being information relating to the braking ability on the route section. The first vehicle transmits the at least one piece of position-related information to a receiver, the receiver being at least one second vehicle, whereby the braking curves of at least one rail vehicle are adapted according to the situation, thus allowing safety on the route section and the utilization of the section to be improved.
