Abstract: A method is provided for operating an actuator of a steer-by-wire steering system of a motor vehicle in a speed range from standstill to parking and/or maneuvering. In one example, the method includes detecting an instantaneous speed of the motor vehicle, determining a limited steering angle as a function of at least the instantaneous speed, detecting a steering angle demand, and activating an actuator for setting a steering angle of at least one wheel, at least as a function of the steering angle demand and having regard to the limited steering angle.

Abstract: A method is provided for operating an actuator of a steer-by-wire steering system of a motor vehicle at speeds from a standstill up to parking and/or maneuvering speeds. The method includes detecting an instantaneous steering angle of at least one wheel on an axle of the motor vehicle, detecting a steering angle demand, determining a limit value of an acceleration of a drive mechanism of the actuator at least as a function of the instantaneous steering angle, and activating the actuator for setting a steering angle of at least one wheel as a function of the steering angle demand and using the limit value of the acceleration.

Abstract: A method is disclosed for protecting the components of a steer-by-wire steering system, where the steer-by-wire steering system comprises a self-locking spindle drive in which the spindle is displaced linearly by driving a positionally fixed spindle nut in rotation. As a function of the speed of the vehicle, the linear displacement of the spindle relative to the spindle nut is summed continuously with respect to time until a first threshold value has been reached. A control unit, a non-transitory computer-readable storage medium, and a steer-by-wire system are also disclosed.

Abstract: A method is disclosed for a steer-by-wire steering system of a motor vehicle, the system having at least one steering function that requests one or more steering angle changes as target steering angles for at least at one vehicle axle. An arbitration unit (AE) weights the steering angle changes as target steering angles (SLw_i) and, taking into account at least one target steering angle (SLw_i), determines an overall target steering angle (G_SLw). Before the overall target steering angle (G_SLw) is set by an actuator of the steer-by-wire steering system, a check is carried out to see whether a gradient of the overall target steering angle (G_SLw) is smaller than or equal to the gradient of the at least one target steering angle (SLw_i).

Abstract: An assembly for plausibility checking and/or reinitializing a rear wheel steering system of a vehicle having a rear wheel steering unit, which includes at least one rear wheel actuator for adjusting a rear-wheel steering angle and a sensor for detecting the set position of the rear wheel actuator, with at least one reference sensor for detecting a reference signal and with an electronic control unit for carrying out the plausibility check and/or reinitialization of the sensor. The reference sensor is part of a vehicle unit different from the rear wheel steering unit and is designed to detect a vehicle-status-dependent reference signal. Furthermore, the control unit includes at least one mathematical model which, based on the vehicle-status-dependent reference signal, can determine a reference value and/or a reference vehicle status, with which the plausibility check and/or reinitialization can be carried out by the control unit.

Abstract: A grinding tool has a main body having at least one fiber ply embedded in a binder. An abrasive layer is arranged on the main body. The at least one fiber ply is arranged in the binder in a partially movable manner. As a result, a relative movement that ensures high vibration and noise damping is achieved within the main body and within the at least one fiber ply.

Abstract: In order to regulate an illuminance, an actual value of a sensor (3) is queried, said value being dependent on the illuminance to be regulated and being regulated to a setpoint value. In a control step, an electronic computing device (11) determines an actuating step for an illuminant (2) on the basis of said actual value and a parameter value of a control parameter. The electronic computing device (11) determines a new parameter value of the control parameter for a subsequent control step on the basis of a first actual value which is received before the corresponding control step, and a second actual value which is determined after the corresponding control step.
