  • Publication number: 20240383491
    Abstract: A method for generating a populated state transition table for a finite-state machine (FSM)-modeled system includes receiving system traits via a host computer of a modeling system. The system traits include states, state transitions, and events of the FSM-modeled system. The method includes generating an initial state transition table in response to receipt of the system traits, the table being partially-populated by the system traits. The method additionally includes populating the table in response to user inputs to thereby auto-generate a populated state transition table, and error-checking the populated table using predetermined error-checking criteria, including searching the populated table via error-checking logic of the host computer for an omitted critical trait of the FSM-modeled system. The method also includes communicating an alert to the user in response to the omitted critical trait.

  • Publication number: 20240383439
    Abstract: Presented are vehicle control systems and logic for provisioning remote vehicle services (RVS), methods for making/using such systems, and wireless-enabled vehicles executing RVS operations governed by such systems. A method of controlling an RVS operation of a vehicle includes a vehicle controller receiving, either directly or indirectly, a request to activate the RVS operation. Responsive to receiving the RVS activation request, wireless signal data is collected to determine wireless signal states of the subject vehicle and of multiple crowd-sourced vehicles proximal to the subject vehicle. Using the host vehicle's and crowd-sourced vehicles' wireless signal states, a signal state heatmap is generated with a spatial mapping of signal state magnitudes as a map overlay. The heatmap visualizes a signal state magnitude in an area surrounding the host vehicle.

  • Publication number: 20240383472
    Abstract: An autonomous vehicle (AV) detects an animal in its vicinity, classifies the detected animal, and selects an action to take based on the classification. The action may be selected to deter the animal away from a roadway along which the AV is traveling, or for the AV to avoid a collision or other negative encounter with the animal. The AV determines whether to proceed along the roadway, e.g., if the action has caused the animal to leave the roadway. The animal classification may be used to determine whether or not to drop off or pick up a user at a particular location near an animal.
