The invention relates to a transponder which is mounted in a tire. The transponder includes at least a transponder chip and a transponder antenna and is embedded in a substrate. The substrate is connected to an inner side of the tire by a connecting structure. In order to provide a transponder with the longest possible service life, the substrate is decoupled from the inner side of the tire via a connecting structure in the form of a soft or gliding support in such a manner that no or only minimum mechanical stresses are transmitted to the substrate. The connecting structure is arranged between the substrate and the inner side of the tire.

A brake system for a vehicle includes brake cylinders operated by pressurized fluid for actuation of brakes by means of pressurized fluid on at least one first axle of the vehicle. The brakes on at least one other, second, axle can be actuated exclusively electromechanically in response to an electrical braking request signal. The pressure of the pressurized fluid can be modulated indirectly or directly and the electrical braking request signal can be generated indirectly or directly in response to actuation of a brake pedal of a brake pedal device. A service brake function is provided by means of hybrid use of the brakes on the first axle(s) together with the brakes on the second axle(s). The brake cylinders operated by pressurized fluid are pneumatically operated brake cylinders. The pressure modulated by the brake pedal device is a pneumatic pressure, and the pressurized fluid is compressed air.

A valve device for brake control of a different pressure medium-operated vehicle brake systems comprises a housing that has pressure medium ducts. A relay valve provides a pneumatic control pressure, which is fed to the relay valve via at least one of the pressure medium ducts at a higher flow rate. At least one insert is pneumatically connected to at least two of the pressure medium ducts, which can be pneumatically connected to each other by the insert. The two pressure medium ducts define a pressure medium path, the profile of which differs based on the housing that is in each case selected and/or switched based on the selected insert. The housing is selected from a set of housings having different pressure medium ducts, in particular bores, but which are otherwise essentially similar. The insert is selected from a set of different inserts.

A vehicle braking unit comprises an operating braking pressure inlet which receives an inlet braking pressure built up by a braking cylinder, and at least one operating brake pressure outlet at which an outlet braking pressure is provided for an operating brake modulator, which is upstream of the operating brake and provides anti-lock functionality. At least one connecting channel hydraulically connects the operating brake pressure inlet to the outlet. Brake fluid is supplied from a storage unit through the brake cylinder, the connecting channel and the operating brake modulator. The braking unit has a brake fluid inlet, through which the brake fluid is received from the storage unit, a brake fluid pump, by which the brake fluid is suctioned through the brake fluid inlet and a supply pressure is built up, and a valve unit that controls the outlet braking pressure and/or a parking brake release pressure by the supply pressure.

An actuating device includes a vehicle operating brake and parking brake. A first braking effect is generated by the parking brake independently of a braking procedure for the operating brake. The actuating device comprises a first switched state, wherein the first braking effect of the parking brake cannot be provided, and a second switched state, wherein the first (full) braking effect of the parking brake is provided. The actuating device further comprises a manually actuatable operating element for actuating the parking brake that comprises travel positions. The actuating device is switched to the second switched state in a first travel position when the parking brake is released, and to the first switched state when the parking brake is applied. Also, the actuating device is switchable to a further switched state. In an actuating method, the actuating device is switched to the further switched state in response to an actuation.

In a device and method for controlling the driving dynamics of a vehicle having a driver's cab spring mounted with respect to the vehicle frame, the yaw rate and deflection of the driver's cab are detected. A yaw rate sensor is arranged in the driver's cab, and the yaw rate of the vehicle frame is estimated or calculated from the yaw rate and deflection of the driver's cab. If the difference between the estimated or calculated yaw rate of the vehicle frame and a desired yaw rate exceeds a limit value, the brake system and/or the drive are actuated.

The invention relates to a control device (3) for a compressed air preparation device (1) of a vehicle (2), wherein the control device (3) outputs output signals for adjusting feed phases and regeneration phases of the compressed air preparation device (1), wherein a compressor (4) feeds compressed air via an air dryer having a desiccant (6a) into a compressed air reservoir (8) in a feed phase, and compressed air is fed out of the compressed air reservoir (8) through the air dryer (6) for drying the desicant (6a) in a regeneration phase. According to the invention, the control device (3) adjusts the regeneration phases depending on a current or future engine load and/or a current or future consumption of compressed air by the vehicle (2). Particularly in coasting phases, excessive drying of the desiccant to a low moisture can occur, in order to save fuel in later travel segments. Route-optimized regeneration of the desiccant as a function of engine load and/or utilization phases is also possible.
