  • Patent number: 11912080
    Abstract: A hitch system for automatically coupling a hitch accessory that has an attachment bar assembly with a hitch receiver. The attachment bar assembly includes a housing bar that is tubular, with a pin-hole through the housing bar. A pin-lever is pivotably mounted in the housing bar and includes a pin configured to retract into the housing bar and to extend out of the pin-hole. A ramp-component is disposed in the housing bar and is engageable with the pin-lever. An actuator selectively moves the ramp-component to retract the pin into the housing bar and to extend the pin out of the housing bar, by selectively enabling pivoting of the pin-lever.

  • Publication number: 20230401872
    Abstract: A dimension calculation system in a host vehicle for dynamically calculating a vehicle dimension using solar shadow information is disclosed. The system is configured to: calculate solar position and an expected vehicle shadow based on geocode location, time and vehicle dynamics; detect an actual vehicle shadow in an image from a vehicle camera; compare the actual vehicle shadow to an expected vehicle shadow; determine a dimension profile and max height point for a vehicle plus vehicle cargo based on a comparison of the actual vehicle shadow to the expected vehicle shadow; calculate a confidence level for the dimension profile and max height point for the vehicle plus cargo; and use the dimension profile and max height point to provide one or more dimension notifications when the confidence level for the dimension profile and max height point for the vehicle plus cargo are above a first threshold level.

  • Patent number: 11772645
    Abstract: A system for predicting a door opening event of a vehicle includes an identity recognition device associated with an individual occupant profile. The system also includes one or more controllers in electronic communication with the identity recognition device, where the one or more controllers store one or more individual occupant profiles in memory of the one or more controllers that includes historical occupant behavior exhibited by one or more occupants associated with the identity recognition device. The one or more controllers execute instructions to determine a predetermined condition has occurred, where the predetermined condition indicates the vehicle is undergoing a potential engine off event. The one or more controllers determine a door opening event probability value based on at least the gear position probability value and the engine off probability value.
