Publication number: 20240001954Abstract: 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.Type: ApplicationFiled: June 30, 2022Publication date: January 4, 2024Applicant: GM Cruise Holdings LLCInventors: Jaimin Liang-Yan Hsu, Charles Bruce Matlack, Sarah M.

Publication number: 20240003695Abstract: Service disruption prevention through monitoring dynamic geofencing is disclosed. The present disclosure seeks to prevent (or drastically reduce the probability) mass vehicle recovery events due to fragile portions of the map. Tooling is used to actively monitor chokepoints and new avoidance areas. Comprised by the operational design domain (ODD), geofences are actively changed in response to the state of the chokepoints and avoidance areas. Varying states can be assigned to a plurality of geofences within the ODD, for example, if a geofence reaches a critical state, one or more areas can be cut off from the ODD.Type: ApplicationFiled: June 30, 2022Publication date: January 4, 2024Applicant: GM Cruise Holdings LLCInventors: Jaimin Liang-Yan Hsu, Charles Bruce Matlack, Sarah M.

Publication number: 20240004056Abstract: 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.Type: ApplicationFiled: June 30, 2022Publication date: January 4, 2024Applicant: GM Cruise Holdings LLCInventor: Daniel Flores Tapia

Publication number: 20240004023Abstract: 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.Type: ApplicationFiled: June 30, 2022Publication date: January 4, 2024Applicant: GM Cruise Holdings LLCInventor: Burkay Donderici

Publication number: 20240004961Abstract: 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.Type: ApplicationFiled: June 30, 2022Publication date: January 4, 2024Applicant: GM Cruise Holdings LLCInventors: Chingiz Bagatur ogly Tairbekov, Logan Jared Perreault

Publication number: 20240004027Abstract: 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.Type: ApplicationFiled: June 30, 2022Publication date: January 4, 2024Applicant: GM Cruise Holdings LLCInventor: Daniel Flores Tapia
