Abstract: A method, for a trailer brake control device of a vehicle trailer with an electric drive, includes receiving at least one acceleration request signal with a requested positive acceleration or a requested negative acceleration and further receiving a status signal with at least one status variable of the electric drive of the vehicle trailer. The method also includes generating, with a controller of the trailer brake control device, at least one brake actuation signal for at least one friction brake of the vehicle trailer and a torque request signal for the electric drive, each based on the at least one acceleration request signal and the status signal. Furthermore, the method includes outputting the brake actuation signal and the torque request signal via at least one output and/or at least one interface of the trailer brake control device.

Abstract: A vehicle network for a plurality of interconnected vehicles is disclosed. The network is in the form of a WLAN and has at least two access points. The access points are interconnected in a wireless manner, i.e., without using a wired backbone. Each access point uses the same radio network ID, so all access points form only one single visible network for WLAN clients. A method for establishing the vehicle network is also disclosed.

The first interface is electrically connected to the second interface to transmit electrical signals and/or data between the first interface and the second interface. A connecting line is configured for connection to a second interface of the plug-in connector device. A vehicle includes a system having the plug-in connector device, and a vehicle has such a system.

Abstract: A method for controlling functions of a vehicle by a remote control unit is provided herein. Signals are transmitted wirelessly between the remote control unit and a station in the vehicle. A data transmission rate depends on a distance between the remote control unit and the station. The data transmission rate is specified. If the data transmission rate is below a defined limit value, the vehicle functions to be controlled are no longer performed or are performed to a restricted extent only and/or the remote control unit emits warning signals.

Abstract: A method for authorization in a wireless vehicle network is disclosed. In particular, the method is for authorizing communication between a mobile communications unit and a vehicle-based communications unit assigned to a control unit in a vehicle, wherein there is an unauthorized connection between the mobile communications unit and the vehicle-based communications unit. In the method, the mobile unit sends to the vehicle-based unit a request to authorize communication. Thereupon, the vehicle-based unit sends to the mobile unit from which the request came, an instruction to perform an action on the vehicle. An operator who has access to the mobile unit and to the vehicle performs the action. The control unit detects the performed action. The vehicle-based unit authorizes communication with the mobile unit.

Abstract: A method is disclosed for establishing and operating a wireless network with a first communication unit, a second communication unit and a mobile communication unit. The first and second communication units are configured in each case as a server and the mobile communication unit is configured as a client. The mobile communication unit acquires connection set-up data of the first and second communication units. A wireless connection is established from the mobile communication unit to the first communication unit. The latter receives an instruction from the mobile communication unit via the wireless connection for configuration as a client of the second communication unit and the mobile communication unit transfers the connection set-up data of the second communication unit to the first communication unit. A wireless connection is then established from the mobile communication unit to the second communication unit.

Abstract: An apparatus and method for effecting wheelbase adjustment for utility vehicles having one or more axles with wheels, includes one or more adjustment mechanisms to which compressed air can be applied. The adjustment mechanism(s) adjust at least one of the axles in relation to the body of the vehicle. A pressure sensor measures the pressure of the compressed air in the adjustment mechanism(s) and generates corresponding pressure signals. A pulse-controlled valve or, alternatively, a spring-return valve, is employed to optionally feed the compressed air into the adjustment mechanism(s) and discharge the compressed air from the adjustment mechanism(s).

Abstract: A tractor-trailer combination includes a semitrailer tractor having a front axle and at least one drive axle having a predefined nominal axle load, a semitrailer having a first axle and at least one second axle, and an axle load adjusting device, which has an axle center height drive for the first axle enabling the axle load acting on the drive axle to be changed by adjusting a center height of the first axle, that can automatically switch into a starting assistance mode in which the second-axle axle load is increased to a starting-assistance axle load that is always below a predefined maximum axle load. An axle center height controller is adapted to automatically detect actuation of an off-road starting sensing device, and increase the second-axle axle load to an off-road starting axle load that is greater than the maximum axle load if the off-road starting sensing device is actuated.
