A method for a utility vehicle, in particular a towing vehicle or a vehicle combination with a utility vehicle, includes the following steps carried out with a control unit of the utility vehicle. A status message is received from an electric drive of the utility vehicle or a trailer vehicle towed by the utility vehicle, which indicates that a braking torque can be provided via the electric drive. An offer message, which indicates an offered braking torque, is then generated depending on the status message. Furthermore, the offer message is sent out to or for at least one further control unit of the utility vehicle. The disclosure includes a braking control unit and a braking system for carrying out the method and a utility vehicle or a vehicle combination with the braking control unit or the braking system. The disclosure includes a computer program product for carrying out the method.

A control arrangement for adjusting a desired distance between two vehicles includes a distance regulation system having a distance control device configured to adjust a first desired distance between a subject vehicle and a vehicle ahead depending on sensor signals received from a sensor system by requesting a first subject vehicle desired acceleration. The control arrangement further includes a communication system configured to wirelessly send and receive a surroundings data signal. The surroundings data signal contains surroundings information. The control arrangement additionally includes an assistance control device configured to determine a second desired distance between the subject vehicle and the vehicle ahead and a second subject vehicle desired acceleration for adjusting the second desired distance depending on the surroundings information received from the communication system. The distance control system comprises an ACC interface. A first interface signal is transferred via the ACC interface to the distance regulation system.

A method for learning braking step threshold values of a sustained-action brake includes detecting a braking requirement setpoint, controlling the sustained-action brake with the braking requirement setpoint to generate a braking effect variable of the sustained-action brake, and detecting a sustained-action brake actual braking effect variable and a maximum sustained-action brake braking effect. The method additionally includes forming a braking effect variable coefficient that characterizes a ratio of the sustained-action brake actual braking effect variable and the maximum sustained-action brake braking effect variable that results from control of the sustained-action brake with the braking requirement setpoint, and assigning the braking effect variable coefficient to a braking step of the sustained-action brake such that each braking step is assigned only one braking effect variable. Additionally, the method includes storing the braking requirement setpoint that results in the braking effect variable coefficient.

A method for controlling a hydraulic servo steering system in a vehicle includes reading out a collision warning signal to establish that a collision assistance case exists, and in response to determining that the collision assistance case exists, providing a hydraulic fluid by a hydraulic pump of the servo steering system. Serving for steering assistance has an actual volumetric flow-rate that is greater than or equal to a minimum volumetric flow-rate. The method additionally includes increasing a pump speed if the actual volumetric flow-rate is less than the minimum volumetric flow-rate, the pump speed being dependent on an engine/motor speed of a drive engine/motor interacting with the hydraulic pump.

A method for controlling a compressed air brake system of a vehicle includes outputting an analog driver brake pressure via a brake pressure control line during driver braking by operating a brake pedal, a switching device set in a driver braking position to a brake circuit with at least one ABS stop valve device, a brake line, and a wheel brake. The method additionally includes, in the presence of both driver braking and the external brake demand signal, measuring the driver brake pressure and determining a driver brake pressure value. Furthermore, the method includes forming a combined brake pressure value by adding or superimposing the driver brake pressure value and an external brake pressure value contained in the external brake demand signal, and switching the switching device into the functional position and controlling the combined brake pressure value from the system pressure by actuating the ABS stop valve device.

In a method and a device for controlling a driver assistance system of a vehicle, a process is carried out which includes the steps of emitting light of at least one wavelength onto a road surface under the vehicle, detecting the light reflected by the road surface, acquiring at least one piece of information on the nature of the road surface using the detected reflected light, transmitting the information on the nature of the road surface to the driver assistance system, and modifying at least one parameter of the driver assistance system such that the driver assistance system reacts depending on the nature of the road surface.

A method and a device for outputting a signal when there is a hazardous surface under a vehicle includes providing an optical surface sensor for determining one or more parameters of the underlying surface, a stationary-state-determining device for determining whether the vehicle is stationary or is to be brought to a standstill, and an output device that outputs a signal if the underlying surface has been determined to be hazardous on the basis of the parameter(s), and the vehicle is stationary or is to be brought to a standstill.
