System and methods for detection and response to interference between trailer coupler and hitch ball
Patent number: 11385651Abstract: A vehicle system comprises a hitch mounted on a vehicle and at least one sensor in connection with the hitch. A controller is configured to identify a force applied to the hitch via the at least one sensor. In response to the force, the controller is further configured to approximate a direction of the force. Based on the direction, the controller generates instructions identifying a height adjustment of a coupler of a trailer.Type: GrantFiled: June 26, 2018Date of Patent: July 12, 2022Assignee: Ford Global Technologies, LLCInventors: Luke Niewiadomski, Erick Michael Lavoie, Rudi Todd Ansbacher, Anton L. Rogness, II, Elliott G. Pearson, Andrew D. Niedert, Joshua Rajasingh, Lucian K. M. Lippok -
Patent number: 10525952Abstract: A Venturi device for producing vacuum from fluids in an engine system has a body defining a Venturi gap separating apart an outlet end of a converging motive section and an inlet end of a diverging discharge section by a lineal distance, and a suction port in fluid communication with the Venturi gap. The converging motive section and the diverging discharge section both gradually, continuously taper toward the Venturi gap, the converging motive section defines a circular-shaped motive inlet and an elliptical- or polygonal-shaped motive outlet, the diverging discharge section defines an elliptical- or polygonal-shaped discharge inlet, and an inner passageway of the converging motive section transitions as a hyperbolic function from the motive inlet to the elliptical- or polygonal-shaped motive outlet.Type: GrantFiled: May 6, 2019Date of Patent: January 7, 2020Assignee: Dayco IP Holdings, LLCInventors: David E. Fletcher, Brian M. Graichen, Keith Hampton, Matthew C. Gilmer, Andrew D. Niedert

Patent number: 10480537Abstract: An evacuator for supplying vacuum to a device in a boosted engine air system is disclosed. The evacuator defines a body comprising a converging motive section, a diverging discharge section, at least one suction port, and a Venturi gap located between an outlet end of the converging motive section and an inlet end of the diverging discharge section. A lineal distance is measured between the outlet end and the inlet end. The lineal distance is decreased in length if higher suction vacuum at a specific set of operating conditions is required and the lineal distances is increased in length if higher suction flow rate at the specific set of operating conditions is required.Type: GrantFiled: April 3, 2019Date of Patent: November 19, 2019Assignee: Dayco IP Holdings, LLCInventors: David E.

Patent number: 10473235Abstract: Check valves are disclosed and include a housing defining an internal cavity having a first seat and a second seat, and a seal member within the internal cavity translatable between a closed position against the first seat and an open position against the second seat. The second seat has a middle axis transverse to a plane of a longitudinal cross-section of the housing and has a shortest finger positioned to either the left or to the right of the middle axis. The seal member is seatable against the second seat at an angle or in a deflected position against the plurality of fingers, thereby defining a longer distance of travel to reach the closed position for a portion of the check valve disc that is associated with the position of the shortest finger relative to other portions of the check valve disc.Type: GrantFiled: June 5, 2018Date of Patent: November 12, 2019Assignee: Dayco IP Holdings, LLCInventors: Andrew D.

Patent number: 10239187Abstract: Methods for post-mold processing a Venturi device for generating vacuum are disclosed that improve the evacuation time thereof. The methods include providing a molded Venturi device having a body defining a Venturi gap between an outlet end of a converging motive passageway and an inlet end of a diverging discharge passageway, where the outlet end defines a motive exit having flash extending radially inward and the inlet end defines a discharge inlet having flash extending radially inward. Then, the method includes positioning the molded Venturi device with an inlet end of the converging motive passageway facing a blasting nozzle or with an outlet end of a diverging discharge passageway facing a blasting nozzle, and propelling blasting media into the motive inlet or the discharge exit of the Venturi device to remove the flash in the motive exit and in the discharge inlet, or vice versa.Type: GrantFiled: June 22, 2016Date of Patent: March 26, 2019Assignee: Dayco IP Holdings, LLCInventors: David E.
