Abstract: A method for operating a transportation vehicle function based on a natural frequency and/or a moment of inertia of a steering wheel arrangement in a steering system including prespecifying an electromotive steering intervention to move the steering system by providing a steering intervention force or a steering intervention torque; ascertaining a natural frequency and/or a moment of inertia of the steering wheel arrangement depending on the response of the steering wheel arrangement based on the electromotive steering intervention; and operating the transportation vehicle function based on the ascertained natural frequency and/or the ascertained moment of inertia of the steering wheel arrangement.

Abstract: A functional module for an operational assistance system of a work apparatus or for a driving assistance system of a transportation vehicle for controlling a function of a piece of equipment of the work apparatus or of the transportation vehicle having a main function unit to produce and provide a function parameter set having at least one function parameter for control of the function of the piece of equipment and having a test and auxiliary function unit. The test and auxiliary function unit tests the function parameter set of the main function unit and takes a result of the test as a basis for outputting the function parameter set of the main function unit in a normal mode of operation to control the function of the piece of equipment.

Abstract: An electromechanical brake booster having a plunger rod for connecting a brake pedal lever to a brake master cylinder, a gear motor, which is coupled with the plunger rod, and a control device for driving the gear motor. A pedal force variable representing the pedal force and a plunger rod motion variable representing the motion of the plunger rod are supplied to the control device as input variables. The control device is configured to determine a setpoint return velocity for the plunger rod with the aid of the plunger rod motion variable and an actual return velocity for the plunger rod and the pedal force variable from the setpoint return velocity and to generate an activation signal for the gear motor. This makes it possible to improve the brake release behavior and to reduce high Bernoulli forces at the end stop for the starting position of the brake pedal lever.
