Publication number: 20240067266Abstract: 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.Type: ApplicationFiled: October 26, 2021Publication date: February 29, 2024Applicant: ZF Friedrichshafen AGInventors: Ingo Dasch, Dominik Vogt, Luc Diebold, Magnus Rau, Björn Spangemacher

Publication number: 20240067265Abstract: 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.Type: ApplicationFiled: October 26, 2021Publication date: February 29, 2024Applicant: ZF Friedrichshafen AGInventors: Ingo Dasch, Dominik Vogt, Luc Diebold, Magnus Rau, Björn Spangemacher

Patent number: 9849886Abstract: A method and device for the combined determining of a momentary vehicle roll angle of a motor vehicle and a momentary roadway cross slope of a curved roadway section traveled by the motor vehicle is disclosed. The momentary vehicle roll angle and momentary roadway cross slope are determined from chassis data and transverse dynamics data of the motor vehicle.Type: GrantFiled: October 31, 2013Date of Patent: December 26, 2017Assignee: Daimler AGInventors: Dieter Ammon, Claus-Michael Hainbuch, Magnus Rau

Patent number: 9694810Abstract: A side wind assistant for a vehicle and a method for the operation of the side wind assistant involve detecting a side wind disturbance acting on the vehicle and reacting to the side wind disturbance by carrying out a side wind compensation intervention to at least partially compensate for the influence of the side wind disturbance, at least when an intervention threshold has been exceeded. The side wind assistant thus reacts to the side wind disturbance in a frequency selective manner in which the frequency selectivity is controlled depending on the side wind compensation or a state of the side wind assistant correlating with the side wind compensation intervention. In particular, the frequency selectivity is controlled depending on whether the side wind compensation intervention is carried out or not carried out, and depending on the duration of the side wind compensation intervention.Type: GrantFiled: December 14, 2011Date of Patent: July 4, 2017Assignee: Daimler AGInventors: Daniel Keppler, Jens Kalkkuhl, Magnus Rau, Van Tuan Tran

Patent number: 9694812Abstract: A method and device for determining a target curve incline of a motor vehicle during traveling of a curved roadway section is disclosed. A momentary transverse acceleration of the motor vehicle is determined depending on a momentary speed of the motor vehicle and a momentary roadway curvature of the curved roadway section determined by an optical detection system. A momentary target curve incline for the motor vehicle is calculated from the determined momentary transverse acceleration. A modified momentary target curve incline is calculated by weighting of the calculated target curve incline with a speed-dependent target curve incline weighting factor. The momentary roadway curvature is determined by additionally using a vehicle navigation system of the motor vehicle.Type: GrantFiled: October 31, 2013Date of Patent: July 4, 2017Assignee: Daimler AGInventors: Dieter Ammon, Claus-Michael Hainbuch, Magnus Rau

Patent number: 8554409Abstract: In a method for influencing the transverse dynamics of a vehicle, a transverse dynamics disturbance variable acting on the vehicle is detected by a disturbance variable determination device and a counter-yaw moment counteracting the transverse dynamics disturbance variable is produced. For this purpose, the dynamic transverse dynamics disturbance variable is detected by the disturbance variable determination device, and a first counter-yaw moment is produced to compensate at least partially for the dynamic transverse dynamics disturbance variable with the help of a first vehicle system. The first counter-yaw moment is reduced following the at least partial compensation, and with the help of the disturbance variable determination device, a check is made whether a stationary transverse dynamics disturbance variable exists. If so, a second counter-yaw moment is produced with the help of a second vehicle system to at least partially compensate for the stationary transverse dynamics disturbance variable.Type: GrantFiled: January 27, 2009Date of Patent: October 8, 2013Assignee: Daimler AGInventors: Jens Kalkkuhl, Daniel Keppler, Magnus Rau, Avshalom Suissa

Patent number: 8116941Abstract: A method is provided for operating an active chassis system, in which wheels of at least one axle are arranged with a toe-in angle, and actuating elements which interact with supporting assemblies which are arranged between the wheels and a vehicle body. Wheel contact forces of the wheels assume different values as a result of the actuating elements being actuated. A side force is generated at the wheels which have a toe-in angle, and a resulting yaw moment is produced. A desired yaw rate is determined based upon information from a device which is arranged in the vehicle in order to determine the profile of the roadway in a control unit, and the wheel contact forces are set as a function of the desired yaw rate.Type: GrantFiled: October 9, 2004Date of Patent: February 14, 2012Assignee: Daimler AGInventors: Dieter Ammon, Carsten Knoeppel, Magnus Rau, Avshalom Suissa
