  • Publication number: 20240012411
    Abstract: The present disclosure relates to vehicle teleoperation and systems and methods for an autonomous-ready vehicle. As an example, the described aspects may provide a variety of functionality, including the use of a teleoperation assembly to provide a third-person perspective for vehicle teleoperation, vehicle width fit checking for a set of obstacles and an associated clearance, semi-autonomous clearance navigation, dynamic vehicle standoff adjustment according to a communication latency associated with teleoperation, vehicle contents change detection and notification generation, path navigation with increased granularity based on ground-engaging member paths, autonomous anchoring for increased traction, vehicle configuration according to a determined three-dimensional center of mass, automatic rocking for improved terrain traversal, audio-aware path generation and vehicle routing, and annunciation of vehicle modes to nearby individuals.

  • Patent number: 8074505
    Abstract: A system for analyzing a substrate material for a diesel or other internal combustion engine exhaust filtration performance includes a valve that actuates within an exhaust system to modulate engine exhaust back pressure and correspondingly maintain a desired filtration velocity to influence a variable parameter within the system, based at least in part on an exhaust characteristic such as a sensed exhaust pressure differential defined across a substrate material.
