Patent number: 11926262Abstract: Adjusting instrument for an exterior vision unit for a vehicle, comprising a base, a foot and a pivoting shaft extending therefrom along a longitudinal axis, and a housing surrounding the pivoting shaft and pivotable around the longitudinal axis in an adjustment range, between at least a park position and a work position. The base and the housing cooperate via cams which interlock in the work position so that the housing is in a stable axial ground position with respect to the foot. The cams, upon pivoting of the housing relative to the base, move apart from the work position along the longitudinal axis, and upon further pivoting are supported on each other, so that the housing is in an axially further removed position with respect to the foot. The adjusting instrument is provided with a detector configured to verify that the housing is in the stable axial ground position.Type: GrantFiled: April 23, 2019Date of Patent: March 12, 2024Assignee: MCi (Mirror Controls International) Netherlands B.V.Inventors: Rudolf Pieter Hoogenboom, Jannick Daniël Wijntjes, Jeyakrishna Sridhar

Patent number: 10259439Abstract: A method for controlling an electric parking brake for a motor vehicle including a brake actuator having an electric motor disposed directly on the brake caliper. When the parking brake is utilized as an additional service brake, depending on a brake pedal brake command, the electric motor is initially energized on detection of an imminent or commencing brake-pedal actuation however the electric motor generates no braking force until a predetermined or specific brake command is received. As a result, an overload of the vehicle voltage source is avoided if simultaneous utilization of multiple parking-brake actuators occurs.Type: GrantFiled: July 31, 2016Date of Patent: April 16, 2019Assignee: Ford Global Technologies, LLCInventors: Marc Suermann, Jill Trappe, Rudolf Daniels, Thomas Svensson

Patent number: 10160430Abstract: A method for operating a service brake system in a vehicle is described. The method includes the stages of determining whether the vehicle is stationary, and detecting whether the brake pressure exceeds a predetermined value in that stationary state. If the brake pressure value exceeds the predetermined value, as part of final stage, the method includes regulating the brake pressure to a predefined limiting value, where the predefined limiting value is sufficient to maintain the vehicle in that stationary state.Type: GrantFiled: July 17, 2013Date of Patent: December 25, 2018Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Thomas Svensson, Rudolf Daniels, Ian Moore

Patent number: 9656653Abstract: The present disclosure provides a hydraulic brake system for a motor vehicle and a method for the detection of a fault condition of the hydraulic brake system. An electronic control device determines at least one pressure value of the brake fluid of the brake system and at least one volume value of the brake master cylinder associated with the pressure value during an operation of a brake master cylinder. The electronic control device compares the determined pressure value and volume value with at least one pair of pressure-volume reference values for the detection of a fault condition of the brake system, wherein at least two different fault conditions of the brake system can be differentiated based on the comparison. The electronic control device is configured to automatically correct the detected fault condition.Type: GrantFiled: April 8, 2015Date of Patent: May 23, 2017Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Thomas Svensson, Rudolf Daniels

Patent number: 9302657Abstract: A method for operating a motor vehicle hydraulic braking system having at least one electric motor-operated braking pressure generator. The output power of the electric motor-operated braking pressure generator is restricted during normal driving/braking situations and the restriction is temporarily deactivated upon identification of a critical driving situation, such as an overstressing of the brake system to include brake fade.Type: GrantFiled: December 21, 2012Date of Patent: April 5, 2016Assignees: Ford Global Technologies, LLC, Robert Bosch GmbHInventors: Rudolf Daniels, Ian Moore, Thomas Svensson, Joerg Riethmueller, Herbert Vollert, Timo Jahnz

Patent number: 9085287Abstract: A method for reducing the braking distance for a vehicle having an anti-lock braking mechanism (ABS) and a hydraulic braking system detects a brake pressure requested by the vehicle's driver (Prequested), and calculates the brakes pressure values at which the wheels of the vehicle lock. A maximum brake pressure value of these different brake pressure values is then compared with the driver's requested brake pressure value (Prequested). If the requested brake pressure value is much higher than the maximum brake pressure value, then the actual brake pressure applied at different wheels (Pactual) is set to a level below the requested brake pressure (Prequested), but still higher than the maximum brake pressure value. This reduces the amount of work required to be done by the ABS in pumping the excessive brake fluid out of the braking system of the vehicle, and allows for precise control of ABS mechanism during wheel slip conditions.Type: GrantFiled: August 11, 2012Date of Patent: July 21, 2015Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Ian Moore, Thomas Svensson, Rudolf Daniels

Patent number: 8788143Abstract: A method for testing a hydraulic braking system. The method includes activating a brake master cylinder of the braking system mechatronically, and measuring a set of measured decision ratios pertaining to the distance travelled by the piston of the brake master cylinder to the corresponding pressure developed in the brake fluid. The measured decision ratios are then compared with a set of reference decision ratios. In a case where the measured decision ratios lie within a predetermined range, it is detected that the braking system is correctly filled with the brake fluid. However, in a case where the measured decision ratios lie outside the predetermined range, it is determined that the braking system has not been correctly filled with the brake fluid and some air is present in the brake fluid flow circuit of the braking system.Type: GrantFiled: May 13, 2013Date of Patent: July 22, 2014Assignee: Ford Global Technologies, LLCInventors: Thomas Svensson, Rudolf Daniels, Ian Moore
