Patent number: 11970037Abstract: A method for controlling a vertical vibration damping of a wheel of a vehicle, in which the wheel has a suspension including a vibration damper with a control element including an actuating element for adapting a damping characteristic of the vibration damper includes a series of steps. The vehicle includes a first sensor for detecting roadway anomalies, a second sensor for detecting a vertical displacement of the wheel, and a control unit connected to the first and second sensors and the control element. The method steps include detecting roadway anomalies with the first sensor, detecting the vertical displacement with the second sensor and switching the vibration damper with the control element at a first point in time from a first state with a first damping characteristic into a second state with a second damping characteristic when a first sensor signal generated by the first sensor indicates a roadway anomaly with a minimum height.Type: GrantFiled: March 9, 2021Date of Patent: April 30, 2024Assignee: Ford Global Technologies, LLCInventors: Cyril Coerman, Uwe Hoffmann, Georg Johann Maurer

Patent number: 11897384Abstract: A vehicle lighting-based roadway obstacle notification for a motor vehicle has a vehicle headlamp system with a controllable light distribution. A camera is aligned parallel to a forward driving direction records a part of the roadway surface lying in front of the motor vehicle which includes a multiplicity of roadway detection paths. Camera data are individually evaluated in relation to ranges and at least one quantity from among a magnitude of a vertical dimension hi of the roadway, a magnitude of a gradient gradx;i of the roadway, and an instantaneous speed vmom of the motor vehicle, with respect to the roadway detection paths. When at least one predetermined condition in respect of at least one of these quantities is complied with, the vehicle headlamp system is controlled in order to illuminate a part of the width of the roadway in which a roadway anomaly has been detected.Type: GrantFiled: December 22, 2022Date of Patent: February 13, 2024Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Georg J.

Patent number: 11766911Abstract: A method is provided for diminishing the effect of roadway anomalies on a vehicle by dynamically adjusting an actuating element for regulating damper forces of a vibration damper of a vehicle wheel when passing over a roadway anomaly, in particular a pothole, wherein, when the falling edge of the roadway anomaly is reached, the actuating element is switched into its hardest setting and, when the rising edge of the roadway anomaly is reached, the force request is set equal to 0 and, thereafter, a force request is calculated based on the parameters of the vehicle and the suspension and is transmitted to the damping.Type: GrantFiled: September 1, 2022Date of Patent: September 26, 2023Assignee: Ford Global Technologies, LLCInventors: Cyril Coerman, Uwe Hoffmann, Georg Johann Maurer

Patent number: 11738618Abstract: A method for checking status of a vibration damper of a motor vehicle includes selecting a suitable section of a roadway, via processing circuitry at a server, based on section selection criteria comprising a number of passing vehicles, a data input sufficient for correlation analyses of the vibration damper, and homogeneity of the roadway. The method further includes acquiring data from a plurality of other vehicles while the other vehicles are driving through the section, grouping data items from the acquired data that are specifically associated with vibration damper status, classifying the status of the vibration damper based on the data items, and informing the driver about the status of the vibration damper. The data on the number of the other vehicles may include data indicative of other vehicle vibration dampers in new condition defining reference values for a degree of wear of the vibration damper.Type: GrantFiled: September 29, 2020Date of Patent: August 29, 2023Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Cyril Coerman, Georg Maurer, Shi Yan

Patent number: 11433891Abstract: A vehicle includes a powerplant, a front axle having first and second wheels and a differential operably coupled to the powerplant. A power-takeoff unit (PTU) is connected to the differential. A rear axle has third and fourth wheels and a gearbox connected to the PTU without a center differential. The gearbox has a first clutch configured to selectively couple the third wheel to the PTU and a second clutch configured to selectively couple the fourth wheel to the PTU. A controller is programmed to determine, during a turn, which of the third and fourth wheels is an outer rear wheel, determine whether there is a positive or negative torque on the outer rear wheel, and disengage, or keep disengaged, the one of the first and second clutches that is associated with the outer rear wheel in response to a negative torque on the outer rear wheel.Type: GrantFiled: March 25, 2020Date of Patent: September 6, 2022Assignee: Ford Global Technologies, LLCInventors: Cyril Coerman, Georg Johann Maurer
