  • Patent number: 12272149
    Abstract: The present disclosure describes systems and methods for automated determination of certain physical characteristics of a trailer in a tractor-trailer truck and positional arrangement between the trailer and tractor of the truck. The technology may include a camera mounted on the tractor to acquire an image of at least a rear portion of the trailer; a sensor configured to acquire information relating to the trailer angle; a processor configured to determine a position of the rear portion of the trailer in the image, and determine the length of the trailer based at least in part on the determined position of the rear portion of the trailer in the image and the information relating to the trailer angle.

  • Patent number: 12257895
    Abstract: The present disclosure relates to systems and methods of automatically distributing powertrain demand between tandem drive axles in a tandem drive axle system for balanced tire wear between the tandem drive axles. Examples described herein analyze input signals collected from various vehicle sensors about operating conditions of the front and back tandem drive axles, and automatically bias a distribution of torque demand between the front and back tandem drive axles to correct for asymmetric wear based on known normal wear of the tires under like operating conditions.

  • Patent number: 12252179
    Abstract: Generally described, an articulated wheel fairing system for a vehicle having a steering system with a neutral steering input and a non-neutral steering input is provided. The articulated wheel fairing system provides clearance to the steer tire and wheel of the vehicle during non-neutral steering input, such as when the vehicle is turning at slower road speeds. The wheel fairing system generally includes an articulating fairing panel configured to cover at least a portion of the steer wheel, where the fairing panel movable from a first position adjacent to the steer wheel, such as when the vehicle is traveling at higher road speeds, to a second position outwardly from the first position. The wheel fairing system includes a mechanical linkage or actuator coupled to the fairing panel and the vehicle and configured to move the frame between the first position and the second position relative to the vehicle.

  • Publication number: 20250084802
    Abstract: An engine control system for a vehicle includes at least one processor; and a memory, operatively connected to the at least one processor and storing instructions that, when executed by the at least one processor and in response to receiving an engine start signal, cause the engine control system to perform a method, the method including causing a crankshaft of an engine of the vehicle to begin to rotate and to rotate through a first plurality of rotations, and causing, for each combustion chamber of at least one combustion chamber of the engine, an exhaust valve of the combustion chamber to remain in an opened position while the crankshaft rotates through the first plurality of rotations and prior to fuel being injected into the combustion chamber.

  • Patent number: 12228057
    Abstract: Exhaust systems are described. In examples, an exhaust flow path couples exhaust ports with one or more turbochargers of an engine. The exhaust flow path may have a portion flowing through a cylinder head (e.g., couplable to the exhaust ports) and a portion flowing through an exhaust manifold (couplable to the cylinder head and the turbocharger(s)). The flow paths may be shaped to reduce the sharpness of turns between the exhaust ports and the turbocharger(s). For example, curves along the flow path may be less than 90 degrees or have a minimum curve radius, which may vary along the flow path. Additionally, at least two, independent flow paths may exist between the exhaust ports and the turbocharger(s). The cross-sectional shape of any part of the flow path may be elliptical, including at inlets and outlets.

  • Publication number: 20250042356
    Abstract: A fuel theft prevention system for a vehicle including: at least one processor; and a memory, operatively connected to the at least one processor and storing instructions that, when executed by the at least one processor, cause the system to: receive, from a first sensing system, first activity data; determine, based on the first activity data, a first confidence value indicative of whether the activity is suspicious; receive fuel data indicative of a fuel level in the fuel tank; and cause, based on the first activity data and the fuel data, at least one mitigation action to be taken when the fuel level decreases by a threshold amount, wherein the threshold amount includes a first amount when the first confidence value is a first value and a second amount when the first confidence value is below the first value, and wherein the second amount is greater than the first amount.

  • Publication number: 20250048495
    Abstract: Systems and methods for modulating power provided to a heating element of a vehicle exhaust system is provided. One system includes a controller controlling a switch, and an alternator having a first field terminal input, wherein the first field terminal input is connected to the switch. The system further includes a heating element connected to at least an output of the alternator. The controller is configured to determine a power demand for the electric heating element and modulate the first field terminal input to cause the alternator to provide power to the heating element according to the power demand.

  • Patent number: 12215780
    Abstract: A system, method, and computer readable storage device are provided for providing a dynamic tachometer. Based on various signal inputs from a plurality of data sources, a tachometer may be dynamically modified to include visual information and assistance to the driver in relation to the vehicle's engine speed (i.e., revolution speed of the vehicle's crankshaft). The tachometer may include one or a combination of: dynamic shift point indicators, a target engine speed range indicator, an overspeed indicator, and a power take-off mode indicator.
