Methods and systems are provided for a vehicle towing a trailer. In one embodiment, a method includes: receiving, by a processor, image data from one or more image sensors of the vehicle; determining, by the processor, a change in vehicle height based on the image data; determining, by the processor, at least one of a vehicle load and a trailer tongue load based on the change in vehicle height; and generating, by the processor, at least one of notification data and control data to control the vehicle based on the at least one of the vehicle load and the trailer tongue load.

Methods and systems for estimating vehicle load and trailer tongue load based on camera images

Methods and systems are provided for controlling towing of a trailer by a vehicle. Sensors are configured to at obtaining sensor data pertaining to the vehicle and the trailer. The non-transitory computer readable storage medium is configured to store parameters that include dimensions pertaining to the vehicle, the trailer, or hitching of the trailer to the vehicle via a hitch. A processor is coupled to the sensors and to the non-transitory computer readable storage medium, and is configured to at least facilitate determining when instability of the trailer is likely to occur at a future time, using the sensor data and the parameters from the non-transitory computer readable storage medium; and taking vehicle actions, in accordance with instructions provided by the processor, when it is determined that the instability of the trailer is likely to occur at the future time.

System and method for trailer instability advanced warning based on hitch load measurement

Methods and systems automatically scale and set trailer brake gain without a need for vehicle driver input and without testing. Scaling a trailer brake gain of a trailer towed by a vehicle includes obtaining sensor data via one or more sensors of the vehicle, including from a hitch load sensor. A processor computes a trailer resistance force of the trailer based on the sensor data. The processor automatically updates the trailer brake gain based on both the sensor data and the trailer resistance force.

Automatic trailer brake gain scaling system and method using hitch forces

Methods and systems automatically scale and set trailer brake gain without a need for vehicle driver input and without testing. Scaling a trailer brake gain of a trailer towed by a vehicle includes obtaining sensor data via one or more sensors of the vehicle. A processor computes a trailer weight of the trailer and a trailer resistance force of the trailer. The processor automatically updates the trailer brake gain based on both the trailer weight and the trailer resistance force and may use vehicle data and axle torque.

Methods and systems for automatic trailer brake gain scaling

Methods and systems are provided for controlling alignment of a vehicle during parking that include obtaining sensor data via one or more sensors of a vehicle, as to passenger occupancy of the vehicle and as to a parking location for the vehicle; identifying, via a processor of the vehicle, which passenger seats of the vehicle are occupied, based on the sensor data; identifying, via the processor, the parking location based on the sensor data; and determining, via the processor, an offset for parking of the vehicle in the parking location, based at least in part on which passenger seats of the vehicle are occupied.

Occupancy based parking alignment for automated and assisted parking

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.

Method to determine vehicle payload, trailer tongue weight, and ride height using underbody cameras

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.

System and method for dynamic dimensioning of vehicle and trailer from shadow profiling

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 (v) 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 (θ); comparing a current vehicle longitudinal speed (v) to the v; automatically generating a speed correction signal to cause the vehicle to slow down below the vwhen the v exceeds the v; 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 v.
