Abstract: In exemplary embodiments, methods and systems are provided that include one or more underbody cameras and a processor for a vehicle. The underbody cameras are configured to obtain camera images under the vehicle. The processor is coupled to the one or more underbody cameras, and is configured to at least facilitate: performing image processing for the camera images; and determining a ride height, a measure of weight on the vehicle, or both, based on the camera images from the one or more underbody cameras and the processing thereof via the processor.

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.

Abstract: Systems, methods, and apparatus are provided in a vehicle to reduce the likelihood of a trailer jackknife condition. The method includes: receiving trailer profile information; receiving a dynamic vehicle steering angle (δ) and dynamic hitch articulation angle (θ) while the vehicle is moving in a reverse direction; continuously calculating a maximum safe vehicle speed (vmax) at which to proceed in reverse without jackknifing based on the trailer profile information, the δ, the θ, a predetermined safe time to jackknife (TTJ_ne), and a maximum hitch articulation angle (θJK); comparing a current vehicle longitudinal speed (v) to the vmax; automatically generating a speed correction signal to cause the vehicle to slow down below the vmax when the v exceeds the vmax; and sending the speed correction signal to a vehicle motion control system to instruct the vehicle motion control system to reduce the v below the vmax.
