Abstract: A towed vehicle detection apparatus for a towing vehicle includes a hose coupling for a hose for supplying pressurized air from the towing vehicle to brakes of the towed vehicle, a sensor configured to detect a physical position of the hose coupling relative to the towing vehicle, and a computer system configured to detect whether the towed vehicle is attached to the towing vehicle based on a signal from the sensor regarding the physical position of the hose coupling. A towing vehicle with a towed vehicle detection apparatus and a method for detecting whether a towed vehicle is attached to a towing vehicle are also provided.

Abstract: A method for handling braking of a combination vehicle (i.e., a towing vehicle and at least one trailer) includes vehicle-specific dynamic updating and implementation of a brake pedal position deceleration map, including utilization of brake pedal position information and vehicle motion information in conjunction with a brake pedal position deceleration map to trigger braking, determining an error in actual deceleration relative to a target deceleration is determined, checking whether compensation for the determined error would be limited by a trailer brake saturation limit, determining an adjustment of brake pedal position to correct deceleration when the determined error is limited by the trailer brake saturation limit, classifying the adjustment into one or more predefined correction categories, updating the brake pedal position deceleration map when the classified adjustment indicates remapping is needed, and utilizing the updated map in actuating brakes of the vehicle.

Abstract: A computer system has processing circuitry configured to handle traction control of a vehicle operating on a surface area is provided. The processing circuitry obtains wheel information indicative of a motion of at least one wheel of the vehicle. The processing circuitry is configured to, based on the obtained wheel information, determine the surface area to be of a surface area type out of a set of surface area types. The processing circuitry is configured to, based on the surface area type, determine a traction control procedure of the vehicle. The traction control procedure comprises a brake control procedure, a differential locking procedure, or a blend of the brake control procedure and the differential locking procedure. The processing circuitry triggers the vehicle to perform the determined traction control procedure.

Abstract: A control unit for determining the number of trailers towed by a tractor unit in a tractor-trailer arrangement, wherein each trailer in the tractor-trailer arrangement comprises reference electrical loads that are controlled by the control unit and powered by a power supply in the tractor unit, and where the control unit is configured to activate one or more reference electrical loads in each trailer, whereby the activated reference electrical loads in each trailer has a known expected power consumption, contributing to a total expected power consumption that scales proportionally with the number of trailers. The control unit further configured to obtain power consumption data pertaining to the one or more reference electrical loads, and determine the number of trailers by analyzing the obtained power consumption data against the known expected power consumption of a single trailer.

Abstract: A control unit for determining the number of trailers towed by a tractor unit in a tractor-trailer combination, wherein the control unit includes a computer vision system for analyzing images. The control unit is configured to: obtain vehicle sensor data, wherein the vehicle sensor data includes a steering angle and images from a left side camera and a right side camera, select images obtained from the left side camera or the right side camera based on the steering angle, wherein a steering angle indicative of a left turn directs image selection from the left side camera, and a steering angle indicative of a right turn directs image selection from the right side camera, and determine the number of trailers towed by the tractor unit by applying the computer vision system to analyze the selected images.

Abstract: A system and method for providing information relative to a connection between a vehicle and at least one trailer. The system comprises a power line communication configured to communicate raw signals on at least one electric power conductor between the or each trailer and the vehicle, the system further comprising a user interface unit and a processing unit, the processing unit being configured to apply signal processing to a raw signal received, to obtain a time domain signal, and transform the time domain signal to a frequency domain signal, use the time domain signal and the frequency domain signal in one or more machine learning models, wherein each machine learning model was previously trained to output an information relative to a connection between the vehicle and the or each trailer, and provide the information to the user interface unit.
