  • Publication number: 20250121710
    Abstract: The present disclosure provides a system and method that determines, by a charging station, that a vehicle is aligned to a predetermined charging position. The predetermined charging position is a location at which a first set of electrical contacts on the charging station aligns with a second set of electrical contacts on the vehicle. The system and method deploys, by the charging station, a charging station interlock system that prevents the vehicle from moving in response to determining that the vehicle is aligned to the predetermined charging position. The system and method charges the vehicle using the first set of electrical contacts coupled to the second set of electrical contacts in response to the deploying of the charging station interlock system.

  • Publication number: 20240403285
    Abstract: This disclosure provides methods and apparatuses for providing interpretability for multivariate time-series data anomaly detection. The multivariate time-series data anomaly detection is performed, through a multivariate time-series data anomaly detection model, for a multivariate time-series data formed by multiple time-series data. An anomaly detection result indicating at least an anomaly period is obtained from the model. An anomaly period correlation metric of the multiple time-series data in the anomaly period is determined. A trace-back period correlation metric of the multiple time-series data in a trace-back period before the anomaly period is determined. At least one time-series data pair having abnormal correlation in the anomaly period is identified from the multiple time-series data, based on a difference between the anomaly period correlation metric and the trace-back period correlation metric.

  • Publication number: 20240278803
    Abstract: Methods, computer systems, and apparatus, including computer programs encoded on computer storage media, for predicting future trajectories for an agent in an environment. A system obtains scene context data characterizing the environment. The scene context data includes data that characterizes a trajectory of an agent in a vicinity of a vehicle in an environment up to a current time point. The system identifies a plurality of initial target locations in the environment. The system further generates, for each of a plurality of target locations that each corresponds to one of the initial target locations, a respective predicted likelihood score that represents a likelihood that the target location will be an intended final location for a future trajectory of the agent starting from the current time point.

  • Patent number: 12066525
    Abstract: Example embodiments relate to techniques for three dimensional (3D) object detection and localization. A computing system may cause a radar unit to transmit radar signals and receive radar reflections relative to an environment of a vehicle. Based on the radar reflections, the computing system may determine a heading and a range for a nearby object. The computing system may also receive an image depicting a portion of the environment that includes the object from a vehicle camera and remove peripheral areas of the image to generate an image patch that focuses upon the object based on the heading and the range for the object. The image patch and the heading and the range for the object can be provided as inputs into a neural network that provides output parameters corresponding to the object, which can be used to control the vehicle.
