  • Publication number: 20240001954
    Abstract: Service disruption prevention through chokepoint identification and monitoring is disclosed. The present disclosure seeks to prevent (or drastically reduce the probability) mass vehicle recovery events due to fragile portions of the map. Choke points are identified by iterating through the lane segments of a map and analyzing the effect of their removal on the service area. Once identified, tooling is used to actively monitor chokepoints using a hybrid polygon with high granularity. Down and upstream effects also can be determined. Based on the monitoring of lane segments and/or areas, location connectivity can be estimated and a map fragility calculated therefrom. If map fragility reaches a critical state, one or more areas can be cut off from the service area.

  • Publication number: 20240004023
    Abstract: An autonomous vehicle (AV) has an electromagnetic (EM) sensor that captures EM sensor data about the environment. The captured EM data is processed to generate an EM map of the environment. The EM data may also be used to identify EM characteristics of the environment. The EM map may be used to modify control and operation of the AV and may also be used to signal conditions to another system managing AVs, to correct localization of the AV, identify anomalies in the environment, and modify a previous signature EM map.

  • Publication number: 20240004027
    Abstract: Adaptive differential quantization for ranging sensors and sensor data encoding is enclosed. The proposed disclosure comprises a differential quantization algorithm that extracts the raw signal data gradients to maximize the amount of effective information (using information theory approaches) transferred to a sensor processing data unit. This approach results in an efficient use of the data links between the sensor suite and a central sensor processing data engine, which can allow the use of cost-effective physical links. The proposed disclosure takes advantage of the gradual environment changes observed in typical vehicular platform trajectories.

  • Publication number: 20240005286
    Abstract: Systems and methods for an automated process for vehicle service. In particular, an individually owned vehicle is integrated with a service provider platform for a fleet of vehicles such that data flows bidirectionally between the vehicle and the platform. The bidirectional flow of data enables an intelligent and automated end-to-end maintenance and/or repair process for the individually owned vehicle, including issue detection, accident management, and seamless vehicle exchange. For example, the vehicle can send a signal to the platform to schedule a repair and request a replacement vehicle from the platform during the repair. The platform can coordinate with a facility to schedule the repair, send a signal to the vehicle to autonomously drive itself to the scheduled repair, and provide a replacement vehicle to the vehicle's home during the repair.

  • Publication number: 20240001963
    Abstract: Vehicles and related systems and methods are provided for controlling a vehicle in an autonomous operating mode. One method involves identifying a stationary object outside a current lane of travel based at least in part on sensor data captured onboard the vehicle, determining an estimated location for the stationary object based at least in part on the sensor data and a location of the vehicle and providing the estimated location to a remote system. The remote system updates lane preference information corresponding to the estimated location for the stationary object when the stationary object satisfies one or more avoidance criteria. The method continues by determining a trajectory for a vehicle to change lanes based at least in part on the updated lane preference information and autonomously operating one or more actuators onboard the vehicle in accordance with the trajectory.

  • Publication number: 20240004961
    Abstract: An actor importance model predicts an actor importance ranking of actors in the environment of an autonomous vehicle (AV). The actors represent detected objects in the environment that may be relevant to perception and planning of the AV. To direct resources of the AV, the actors are ranked in the relative importance to the AV's intent in navigating the environment. The actor importance model may generate embeddings to represent the actors, AV intent, and the overall scene. To train the model, a relative ordering loss may be used that evaluates the relative ordering of the actors with respect to one another, which may be further modified based on a threshold for which further processes are affected by the ranking.

  • Publication number: 20240004056
    Abstract: High-resolution point cloud formation based on the use of a point spread function kernel is disclosed. The proposed disclosure provides the means to generate high angular resolution point clouds by performing a matching process of the point spread function (PSF) to a series of adaptive hypotheses to accurately identify the target signatures using the maximum amount of available information. The proposed method comprises a two-stage processing chain. In the first step, the spatial and the Doppler spectrum of the target responses is calculated and decomposed in terms of the sensor point spread function (PSF). In the second step, the target PSF representation is then processed using a support vector machine to determine the presence of closely located targets that would not be possible to detect using typical automotive RADAR signal processing chains.
