US 12,715,399 B2 · System and method for handling combination vehicle brake torque factor using trailer wheel end air volume

Abstract

A method for handling brake factor of a combination vehicle (i.e., a towing vehicle and at least one trailer) includes sensing a condition indicative of air volume at trailer wheel ends, estimating an air volume for the trailer wheel ends, generating a predicted brake torque factor for the trailer(s) with a trained machine learning model utilizing the estimated air volume, and reconfiguring an electronic control unit of the combination vehicle with the predicted brake torque factor. A corresponding system for handling brake factor of a combination vehicle includes one or more sensors, a processing module, and a control module. The processing module estimates an air volume for trailer wheel ends, and generates a predicted brake torque factor for the trailer(s) with a trained machine learning model. The control module is arranged to reconfigure an ECU of the combination vehicle with the predicted brake torque factor.

Dependent claims

A method for handling a brake torque factor of a combination vehicle including a towing vehicle and at least one trailer, the method comprising:

sensing at least one condition indicative of air volume of trailer wheel ends of the at least one trailer and producing at least one sensor output;
estimating an air volume for the trailer wheel ends of the at least one trailer, utilizing the at least one sensor output obtained from one or more sensors configured to sense the at least one condition indicative of air volume of trailer wheel ends of the at least one trailer;
generating, by a trained machine learning model, a predicted brake torque factor for the at least one trailer utilizing at least one input, wherein the at least one input comprises the estimated air volume;
and
reconfiguring an electronic control unit of the combination vehicle with the predicted brake torque factor to permit the electronic control unit to utilize the predicted brake torque factor in adjusting a brake pressure request sent to the at least one trailer to achieve a desired brake torque at the at least one trailer and attain a targeted deceleration of the combination vehicle.
