VEHICLE AND TRAILER LOAD DETERMINATION
A towing configuration of a vehicle coupled to a trailer may be evaluated by rolling a tire of the coupled vehicle and trailer over a compressible region of a pressure vessel filled with a hydraulic fluid. A peak pressure of the hydraulic fluid as the tire rolls over the compressible region of the pressure vessel may be determined. The tire load may be determined based upon the peak pressure. Based at least in part on the tire load, a determination may be made whether the towing configuration satisfies a predetermined set of criteria.
Automated vehicle control system architecture
Controllers, control architectures, systems and methods are described for controlling a host vehicle's participation in a platoon. Described vehicle platooning control systems may include a platoon controller and a vehicle interface controller. The platoon controller is configured to determine torque and braking requests for at least partially automatically controlling the host vehicle to platoon with a platoon partner. The vehicle interface controller manages communications between the platoon controller and one or more host vehicle control units. The vehicle interface controller may also include a safety monitor including one or more safety monitoring algorithms In some embodiments, the vehicle interface controller is at least ASIL-C compliant, whereas the platoon controller and an optional gateway processor may be QM rated under ISO 26262. The platoon controller may be configured as a listener capable of receiving but not transmitting messages on the host vehicle's control related communication bus(es).
Self-driving vehicles and weigh station operation
The technology involves operation of a self-driving truck or other cargo vehicle when it is being inspected at a weigh station. This may include determining whether a weigh station is open for inspection. Once at the weigh station, the vehicle may follow instructions of an inspection officer or autonomous inspection system. The vehicle may perform predefined actions or operations so that various vehicle systems and safety issues can be evaluated, such as the brakes, lights, tires, connections between the tractor and trailer, exposed fuel tanks, leaks, etc. A visual inspection may be performed to ensure the load is secured, vehicle and cargo documents meet certain criteria, and the carrier's safety record meets any requirements. In addition, the weigh station itself may be operated in a partly or fully autonomous mode when dealing with autonomous and manually driven vehicles.
Stress distribution measurement method and stress distribution measurement system
A stress distribution measurement method is a method of measuring stress distribution generated on a structural object including two support parts and a beam part provided between the support parts. The method includes: generating first image data by performing, through a first image capturing unit, image capturing of a moving object or an identification display object attached to the structural object from the moving object; calculating, based on the first image data, a movement duration in which the moving object moves between the support parts; generating, as second image data, thermal image data by performing image capturing of the surface of the beam part through a second image capturing unit; calculating a temperature change amount based on a second image data group corresponding to the movement duration; and calculating a stress change amount based on the temperature change amount to calculate stress distribution based on the stress change amount.
AXLE LOAD MEASURING APPARATUS AND AXLE LOAD MEASURING METHOD
An axle load measuring apparatus includes a displacement calculator, a storage, and an axle load calculator. The displacement calculator detects displacements of positions on a road caused by an axle load using a captured image of the road and a vehicle thereon. When a certain amount of load is applied to a predetermined position of the road, the storage stores a displacement function representing shape information of a spatial distribution of a displacement of the road originated from the predetermined position. The axle load calculator calculates the axle load based on the displacements of the positions and the displacement function.

Method and apparatus for peak weight detection
A method for determining a peak weight associated with an agricultural machine includes the step of determining a weight associated with the agricultural machine. Operational parameters are stored in response to determining that the weight is above a threshold. The threshold can be based on a maximum weight associated with the agricultural machine and set via user input to a machine control indicator. In one embodiment, a new weight associated with the agricultural machine is determined. The new weight is compared to a previous peak weight associated with the agricultural machine. The new weight is stored as a peak weight in response to determining that the new weight is higher than the previous peak weight. Operational parameters associated with the new weight can also be stored in response to determining that the new weight is higher than the previous peak weight.
