  • Publication number: 20190300069
    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.

  • Patent number: 10416043
    Abstract: Systems and methods for improving fuel economy in vehicles such as Class 8 trucks are provided. In some embodiments, signals indicating states of the powertrain are collected and used to generate fuel rate optimization values. Fuel rate optimization values may indicate a difference between optimum fuel flow rates and actual fuel flow rates during a vehicle drive cycle. Recorded fuel rate optimization values may be used to compare different vehicle configurations during testing, and may also be used to evaluate vehicle performance during real-world operation.

  • Patent number: 10392998
    Abstract: A system for estimating an amount of soot in an exhaust particulate filter includes a delta P soot load estimate generator configured to generate a first soot load estimate as a function of a pressure drop and a mass flow of exhaust. The system further includes a model estimate generator configured to generate a second soot load estimate as a function of a modeled engine performance. A trust factor generator is configured to determine a trust factor signal as a function of at least one engine operating characteristic, and a decision generator is configured to determine whether to use the first soot load estimate or the second soot load estimate as a function of the trust factor signal.

  • Publication number: 20190248280
    Abstract: A platooning light fence includes an illumination assembly having one or more light sources located on at least one of a first platooning truck and a second platooning truck, each of the one or more light sources configured to radiate a beam of light that extends substantially continuously between the first and second platooning trucks. A system for deterring passenger vehicles from entering a gap defined between at least a leading platooning truck and a trailing platooning truck includes an illumination assembly having one or more light sources located on at least one of the leading platooning truck and the trailing platooning truck, each of the one or more light sources configured to radiate a beam of light that extends substantially continuously between the leading and trailing platooning trucks, and an activation assembly configured to selectively activate the illumination assembly.

  • Publication number: 20190251747
    Abstract: In some embodiments of the present disclosure, augmented reality and/or virtual reality technologies are used to present information for a vehicle to a technician. A virtual object model file that includes a context model and at least one assembly detail model is created based on a vehicle design model. A VR/AR device uses its camera to generate video of a vehicle, and superimposes a depiction of a vehicle component or assembly from the virtual object model file over the video in the location in which the vehicle component or assembly is actually located, as if the vehicle were “see-through.” The VR/AR device may then also allow the technician to select specific components of the depicted assembly in order to retrieve and display detailed information about the component.

  • Patent number: 10371077
    Abstract: In some embodiments, a vehicle is provided having improved fuel economy by using gradual engine speed control. Once a governor activation threshold is crossed, a dynamic engine speed limit that gradually increases over time is implemented. In some embodiments, if the engine speed does not continue to rise over time, increases in the dynamic engine speed limit may be paused. In some embodiments, if the engine speed increases at too great of a rate for too long of a time, the dynamic engine speed limit may be reset. In some embodiments, increasing, pausing, and/or resetting the dynamic engine speed limit allows gradual acceleration while also avoiding torque lock.

  • Patent number: 10373378
    Abstract: The present disclosure relates to systems and methods for providing various types of information to a vehicle driver. Such information can be used by the vehicle driver singularly or in conjunction with other information available to the vehicle driver in order to allow the driver to operate the vehicle in an increasingly safe manner and/or to reduce the likelihood of property damage and/or possible bodily injuries to the driver, etc. In some instances, such information is presented to the driver as an augmented reality environment such that the driver can “see through” objects that may be occluding the driver's vision.

  • Publication number: 20190234332
    Abstract: A method of controlling an idle speed for an engine of a vehicle includes the steps of sensing a vehicle speed. At least one of a parking brake position and a clutch position is also sensed. When it is determined that the vehicle speed is below a maximum vehicle speed, and either the parking brake is released or the clutch is depressed, the engine idle speed is increased from a base idle speed to a launch idle speed.

  • Publication number: 20190195351
    Abstract: A computer system (e.g., an on-board vehicle computer system) creates or updates a mapping of transmission gears and respective driveline ratios during operation of the vehicle. The system obtains a current engine speed and vehicle speed and calculates a current driveline ratio for the vehicle based on the current engine speed and vehicle speed. If the driveline is engaged, the system updates the mapping based at least in part on the current driveline ratio. Performing the update may include adding a new transmission gear or updating an existing transmission gear in the mapping, or removing a duplicate transmission gear from the mapping. Applications include cruise control, predictive cruise control, predictive shifting, and selecting a gear for a specific purpose (e.g., for descending a hill).

  • Publication number: 20190160942
    Abstract: A mobile computing device presents a set of user interface (UI) elements and receives user input corresponding to a set of vehicle specification values (e.g., engine type, transmission type, axle ratio) via the set of UI elements. The mobile computing device obtains (e.g., from a remote computer system hosted by a vehicle manufacturer) a vehicle performance value (e.g., a fuel economy value or a greenhouse gas emission value), an optimization value for the vehicle performance value, and vehicle specification analysis information based at least in part on the set of vehicle specification values. The mobile computing device presents the vehicle performance value, the optimization value, and vehicle specification feedback to a user. The vehicle specification feedback is based at least in part on the optimization value and the vehicle specification analysis information.
