Patent number: 11731471Abstract: A fifth wheel system includes a fifth wheel configured to couple to a kingpin of a towed trailer such that vibrations are generated when the fifth wheel couples to the kingpin. A sensor in operative association with the fifth wheel and configured to sense the vibrations and generates vibration data. A controller receives the vibration data and processes the vibration data to detect a presence or an absence of a predetermined vibration component that occurs when the fifth wheel properly couples to the kingpin. An indicator indicates proper coupling of the fifth wheel to the kingpin when the predetermined vibration component is present.Type: GrantFiled: April 25, 2019Date of Patent: August 22, 2023Assignee: Fontaine Fifth Wheel CompanyInventors: Carl Gaufin, Ryan Fechner
