  • Publication number: 20250074445
    Abstract: A vehicle includes a ranged sensor that generates time-series data indicating positions of objects in an environment surrounding the vehicle, a user interface configured to warn the driver of a predicted collision between the vehicle and one of the objects in the environment, and at least one processor including an ECU operatively connected to the ranged sensor and the user interface. The processor records control inputs by the driver driving the vehicle, and develops a driver behavior model associated with the driver driving the vehicle based on the control inputs. The processor also predicts trajectories of the objects and the vehicle based on the time-series data and the driver behavior model, and predicts a collision between the vehicle and one of the objects based on the predicted trajectories. The processor also generates a warning indicating the predicted collision to the driver.

  • Publication number: 20240404297
    Abstract: Systems and methods for training a neural network for generating a reasoning statement are provided. In one embodiment, a method includes receiving sensor data from a perspective of an ego agent. The method includes identifying a plurality of captured objects in the at least one roadway environment. The method includes receiving a set of ranking classifications for a captured object of the plurality of captured objects. The annotator reasoning statement is a natural language explanation for the applied attribute. The method includes generating a training dataset for the object type including the annotator reasoning statements of the set of ranking classifications that include the applied attribute from the plurality of importance attributes in the importance category. The method includes training the neural network to generate a generated reasoning statement based on the training dataset in response to a training agent detecting a detected object of the object type.

  • Publication number: 20240394309
    Abstract: According to one aspect, causal graph chain reasoning predictions may be implemented by generating a causal graph of one or more participants within an operating environment including an ego-vehicle, one or more agents, and one or more potential obstacles, generating a prediction for each participant within the operating environment based on the causal graph, and generating an action for the ego-vehicle based on the prediction for each participant within the operating environment. Nodes of the causal graph may represent the ego-vehicle or one or more of the agents. Edges of the causal graph may represent a causal relationship between two nodes of the causal graph. The causal relationship may be a leader-follower relationship, a trajectory-dependency relationship, or a collision relationship.

  • Publication number: 20240330651
    Abstract: According to one aspect, discovering interpretable dynamically evolving relations (DIDER) may including using a DIDER model for multi-agent interactions represented by an execution set of edge embeddings indicative of trajectory interactions between two or more agents for one or more time steps. The DIDER model may be trained by feeding a training set of edge embeddings to a long short-term memory network (LSTM) forward to generate an LSTM forward output, feeding the training set of edge embeddings to a LSTM reverse to generate an LSTM reverse output, feeding the LSTM forward output to a duration encoder to generate an edge duration output, and training the DIDER model based on a probability distribution for one or more different edge types obtained by feeding the LSTM forward output or the LSTM reverse output to an edge prior and an edge encoder.

  • Publication number: 20230202525
    Abstract: A system and method for providing a situational awareness based adaptive driver vehicle interface that include receiving data associated with a driving scene of an ego vehicle and eye gaze data and analyzing the driving scene and the eye gaze data and performing real time fixation detection pertaining to the driver's eye gaze behavior to determine a level of situational awareness with respect to objects that are located within the driving scene. The system and method also include determining at least one level of importance associated with each of the objects and communicating control signals to control at least one component based on at least one of: the at least one level of importance associated with each of the objects that are located within the driving scene and the level of situational awareness with respect to each of the objects that are located within the driving scene.

  • Patent number: 10941843
    Abstract: A telescopic differential screw mechanism based 3-DOF Parallel Manipulator system to enable differential length and omnidirectional bending is provided. The telescopic differential screw mechanism based 3-DOF Parallel Manipulator system includes a first circular rotating plate 102, a second circular rotating plate 104, three or more telescopic screw assemblies 106A-C and three or more actuators 108A-C. Each telescopic screw assembly 106 includes a pair of master screws 110, a pair of successive screws 112 and a universal joint 116. The three or more telescopic screw assemblies 106A-C are actuated differentially using the three or more actuators 108A-C to achieve omnidirectional bending with high angular rotations in a range of 0 to 75 degree.
