A method for the automated driving of a transportation vehicle, having at least one control device for calculating a trajectory, wherein control commands for actuators for setting longitudinal and lateral guidance of the transportation vehicle are calculated for the trajectory and are implemented by the actuators, wherein the control commands are updated at fixed points in time, wherein at each point in time a current emergency trajectory for bringing the transportation vehicle to a standstill is calculated, wherein a set of control commands for actuators for setting at least the lateral guidance are calculated for the emergency trajectory and, in the absence of the control commands for the trajectory, are automatically implemented by the actuators for the emergency trajectory. Also disclosed is an automated transportation vehicle.

Method for the automated driving of a motor vehicle, and automated motor vehicle

An operating method for a steer-by-wire steering system having a steering gear module, a steering wheel module, and a bus connecting the steering gear module and the steering wheel module, wherein an actual position in the steering gear module is sensed and a setpoint position in the steering wheel module is adjusted in relation to the actual position in the steering gear module by using an association specification. Also disclosed is a control unit for a steer-by-wire steering system, a steer-by-wire steering system, and a transportation vehicle having a steer-by-wire steering system.

Operating method for a steer-by-wire steering system, control unit for a steer-by-wire steering system, steer-by-wire steering system, and transportation vehicle

A steering control system for operating a steering system for a transportation vehicle according to a steering intervention specification by making available a steering intervention variable, the system having computing units to redundantly calculate a manipulated variable according to a specified calculation algorithm as a function of the steering intervention specification and one or more operating state variables; a switching device for always making available one of the manipulated variables of the computing units as the steering intervention variable to the steering system; and a monitoring device to check the functional capability of the computing units, wherein the switching device is actuated as a function of the result of the check.

Steering control system for a steering system of a transportation vehicle and method for operating a steering control system

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.

Method and device for operating a transportation vehicle function

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.

Functional module, control unit for an operation assistance system, and device

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.
