  • Publication number: 20240217541
    Abstract: A vehicle capability broadcaster may receive information indicating a condition in an environment where an AV may operate. The vehicle capability broadcaster determines a first vehicle capability parameter and a second vehicle capability parameter based on the condition. The vehicle capability parameters may indicate capabilities of the AV for making different types of motions, e.g., limits of the AV making different motions. The vehicle capability broadcaster may transmit the first vehicle capability parameter to a first planning module and transmit the second vehicle capability parameter to a second planning module. The first planning module and the second planning module may plan one or more motions of the AV in the operation based on the vehicle capability parameters. The vehicle capability broadcaster may update a vehicle capability parameter and transmit the updated vehicle capability parameter to one of the planning modules after the one or more motions are planned.

  • Publication number: 20240219905
    Abstract: Autonomous vehicles may encounter situations prompting the autonomous vehicle to execute a stopping maneuver, or receive user input from a passenger of the autonomous vehicle that may cause the autonomous vehicle to execute a stopping maneuver (that is not part of nominal planning of the present mission of the autonomous vehicle). In some cases, the autonomous vehicle's mission may be interrupted. Such situations and user input may be diverse. Also, there may be many kinds of stopping maneuvers that the autonomous vehicle can execute in response to the situation or user input. Monitoring for the situations and user input, managing mission interruptions, and performing continuation of a mission can be non-trivial tasks to perform gracefully and effectively.

  • Publication number: 20240217551
    Abstract: Systems and methods for measuring passenger comfort and trading off passenger comfort with other metrics in autonomous vehicle planning and control. Perception of kinematic comfort relative to acceleration can vary depending on the frequency of acceleration. Systems and methods are provided to use the relationship between kinematic comfort and acceleration to introduce a cost on the ratio between acceleration and jerk. In various examples, the resulting cost can be traded off against other cost terms such as obstacle buffers and reference tracking constraints. Autonomous vehicle planning and control problem formulations can be encoded to include a direct tradeoff between both lateral and longitudinal comfort metrics and other variables.

  • Patent number: 12023757
    Abstract: Air management systems are provided for optimizing airflow in laser welding with deflectors. A system for a welder includes a blower to generate an airflow stream. A plenum receives the airflow stream, directs it toward the workpiece, and defines an outlet facing the workpiece to expel the airflow stream toward the workpiece. A deflector adjacent the outlet is formed as a conical section converging from the plenum toward the workpiece, and is defined by an angled wall with an open center. The deflector concentrates the airflow stream to impart a velocity increase to the airflow stream after leaving the outlet and to impart a favorable directional component to the airflow stream toward a weld zone, as well as protecting the laser lens by increasing the downward momentum force of the air stream to eliminate the potential of spatter impinging the lens.
