20150191158 | METHOD FOR OPERATING A WHEEL SLIP CONTROL APPARATUS WITH COMPENSATED WHEEL SPEEDS - A method and device for operating a wheel slip control apparatus, including determining wheel speeds of wheels compensated with respect to wheel speed differences during a turn as input variables for the wheel slip control apparatus, with which a) a neutral steering, understeering or oversteering driving condition of the vehicle is determined from the driving behavior during a turn, b) depending on the determined condition of the vehicle, either the reference or actual yaw rate is used to calculate a turn radius related to a selected point on the vehicle, c) wheel-related turn radii for at least some wheels are determined from the turn radius related to the selected point, d) reference factors are determined from the wheel-related turn radii and a common reference turn radius for at least some wheels, and e) the compensated wheel speeds are each determined from the reference factors and measured wheel speeds for at least some wheels, and f) the compensated wheel speeds are used as input variables for a wheel slip control apparatus. | 07-09-2015 |
20150025766 | TRAILER ACCESS POINT PAIRING - A trailer electronic braking system includes a braking device capable of generating a braking force on a wheel on the trailer, a brake force into the brake cylinders being controllable by a braking ECU. The braking ECU is connected to a standards compliant communication bus on said trailer and is adapted to receive data inputs from sensors on the trailer. An interface to trailer electronics and a communications interface are also provided. The brake system is further adapted to transmit a trailer identifier such as an SSID, such that the trailer identifier can be paired with a further device, such as a mobile telephone associated with a tractor driver, the further device having previously been provided with the trailer identifier. | 01-22-2015 |
20150012199 | TRAILER ACCESS POINT - A trailer electronic braking system includes a braking device capable of generating a braking force on a wheel on the trailer, a brake force into the brake cylinders being controllable by a braking ECU The braking ECU is connected to a standards compliant communication bus on said trailer and is adapted to receive data inputs from sensors on the trailer. An access point adapted to receive inputs from further sensors on the trailer and/or to read the inputs from sensors received by the braking ECU such that data received from the sensors can be rendered in standards compliant manner and wirelessly transmitted to a further device such as a mobile telephone remote or distinct from the trailer. The further device is adapted to display information so received using a standards compliant client such as with a web browser. | 01-08-2015 |
20140103237 | PARKING BRAKE DEVICE - A parking brake device having a bistable parking brake valve, a relay valve, a spring brake and electrically actuable valves, the electrically actuable valves being selectively connectable to the parking brake valve to supply pressure or atmospheric pressure, an outlet of the parking brake valve controls the relay valve, and the relay valve controls the spring brake, in which the parking brake valve has a movable piston, which is loaded by a spring and has two coaxial piston faces which delimit a first space and a second space, in which supply pressure, atmospheric pressure or a pressure which lies between them and which can be fed to the outlet of the parking brake valve can be supplied to the first space in accordance with the position of the piston, and in which the second space can be selectively connected to supply pressure or atmospheric pressure by an electrically actuable valve. | 04-17-2014 |
20120001477 | VALVE ARRANGEMENT FOR CONTROLLING A BRAKE SYSTEM OF A TRAILER VEHICLE - A valve arrangement for controlling a brake system, comprising at least one spring brake cylinder and at least one service brake cylinder, of a trailer vehicle of a traction vehicle-trailer combination, characterized in that said valve arrangement includes a 3/2 way valve which, as a function of the control pressure present at its control inlet, connects either its connection, which is connected to an outlet of a control valve device in order to generate service brake pressure for the at least one service brake cylinder, or connects its connection, which is connected to a trailer-vehicle-side compressed air supply, to its further connection which is connected to the at least one spring brake cylinder. | 01-05-2012 |
20090319135 | HYDRAULIC OR PNEUMATIC CONTROL OF AN AUTOMATED SHIFT TRANSMISSION - The invention concerns a hydraulic or pneumatic control device for an automated shift transmission, comprising actuating devices with actuating cylinders ( | 12-24-2009 |
20090071324 | WATER-COOLED PISTON COMPRESSOR - A water-cooled piston compressor having at least one air-compressing piston, which can be driven with means for producing a linearly oscillating drive force and which is accommodated in an axially movable manner in a cylinder housing which is closed at the end face via a cylinder head and is provided with water-cooling means, wherein the water-cooling means comprise a cylinder housing which is formed with a double wall and on whose end face facing the cylinder head a plurality of cooling openings are arranged, via which coolant flowing through the double-walled cylinder housing comes into contact with the region of the cylinder head. | 03-19-2009 |
20090021720 | SENSOR DEVICE FOR MEASURING THE COMPRESSION TRAVEL AND/OR THE COMPRESSION RATE OF WHEELS AND/OR AXLES OF VEHICLES - A sensor device for measuring the compression travel and/or the compression rate of wheels and/or axles of vehicles, in particular of commercial vehicles, may include at least one sensor measuring in a contactless manner. The sensor device may include a radar and/or high-frequency sensor generating a beam, which is emitted and received after reflection at a reference and reflection surface. | 01-22-2009 |
