  • Publication number: 20230186518
    Abstract: To calibrate a set of sensors with respect to one another, such as the respective position and orientation of the sensors, a sensor calibration system uses a well-measured calibration scene in which the objects within the calibration scene have established positions, and optionally orientations (e.g., rotational directions), within the calibration scene and with respect to one another. The calibration scene is captured by a set of sensors to generate respective sensor views of the scene. Each sensor view is analyzed to detect control objects (e.g., features thereof) with respect to the coordinates of each sensor view. Using the known relationship of the calibration objects within the calibration scene, the sensors are calibrated to determine calibration parameters for a joint coordinate system that the maps the detected positions in the sensor view with the relative positions of the measured calibration scene.

  • Publication number: 20230182601
    Abstract: A method for coordinating a discharge session in which direct current power is offloaded from a power supply, e.g., of an electric vehicle (EV), to a bidirectional offboard charging station includes, in response to connection of the power supply to the charging station via a charging cord set, exchanging charging data between the EV and charging station. This occurs over a low-voltage communication line, with charging data including power and current limits of the EV and charging station. In response to the limits being indicative of negative limits, with the negative limits representing a request for the discharge session, the method includes transmitting the EV power and current limits to the charging station to confirm the request. The discharge session is initiated in response to confirming the request through an exchange of a unique identifier indicating support for the discharge session.

  • Publication number: 20230182766
    Abstract: A sensor calibration system periodically receives scene data from a detector in a calibration scene. The calibration scene includes calibration targets. The sensor calibration system generates a calibration map based on the scene data. The calibration map is a virtual representation of the calibration scene and includes features of the calibration targets that can be used as ground truth features for calibrating AV sensors. The sensor calibration system can periodically update the calibration map. For instance, the sensor calibration system receives the scene data at a predetermined frequency and updates the calibration map every time it receives new scene data. The predetermined frequency may be a frequency of the detector completing a full scan of the calibration scene. The sensor calibration system provides a latest version of the calibration map for being used by an AV to calibrate a sensor on the AV 110.
