摘要： Patterns in lane data and traffic signal data around intersections are used to detect potential errors in map databases and automatically generate data for map databases. Groups of lanes inbound into intersections and/or outbound from intersections can be categorized, and these categories may be used to compare lanes around an intersection, or at multiple intersections along a roadway or in a region. Deviations from expected patterns of these intersection categories may be used to identify errors. Patterns of internal lanes based on external lanes and traffic signal data may be used to automatically generate internal lane data for intersections.

摘要： Machine learning model optimization systems and methods are disclosed. A system receives sensor data captured by one or more sensors of a vehicle during a first time period. The vehicle uses a first trained machine learning (ML) model for one or more decisions of a first decision type during the first time period. The system generates a second trained ML model at least in part by using the sensor data to train the second trained ML model. The system identifies an optimal trained ML model from a plurality of trained ML models. The plurality of trained ML models includes the first trained ML model and the second trained ML model. The system causes the vehicle to use the optimal trained ML model for one or more further decisions of the first decision type during a second time period after the first time period.

摘要： Various technologies described herein pertain to systems and methods for shielding electric circuits from electromagnetic radiation or radio waves. The systems and methods include, for example, a shield having a body with a top portion and a plurality of side portions extending therefrom. The side portions include one or more extensions acting as spring contacts or spring elements and one or more gaps therebetween. The extensions are, for example, either individually or as a group flexible in that they can compress, bend, or otherwise deform under force thus having a spring characteristic that compensates for PCB irregularities (e.g., warping, bending, etc.)

摘要： Various technologies described herein pertain to opportunistically employing passive multistatic radar processing in automotive radar systems. A radar system of an autonomous vehicle is controlled to operate in an active mode during a first time period as the autonomous vehicle travels along a route. A transmitter and receiver of the radar system are enabled in the active mode. The radar system is controlled to operate in a passive mode during a second time period as the autonomous vehicle travels along the route. The transmitter is disabled and receiver is enabled in the passive mode. While in the passive mode, the receiver of the radar system receives a reflected radar signal responsive to a radar signal transmitted by a differing radar system of a differing autonomous vehicle. An object is detected based on the reflected radar signal and transmission information pertaining to the differing radar system of the differing autonomous vehicle.

摘要： Aspects of the disclosed technology provide solutions for autonomous vehicle (AV) data prioritization and in particular, for classifying data stored on an AV based on a prioritization policy. A process of the disclosed technology can include steps for collecting sensor data, wherein the sensor data represents a real-world environment encountered by an autonomous vehicle (AV) and storing the sensor data to a disk drive on the AV. The process can further include steps for receiving, from an autonomous vehicle (AV) fleet center, a prioritization policy, classifying, based on the prioritization policy, the sensor data, and determining if a fill level of the disk drive has exceeded a predetermined threshold. Systems and machine-readable media are also provided.

摘要： 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.

摘要： Systems and methods systems provide for client control over an Autonomous Vehicle (AV). The AV can determine sets of mechanical operations that it can take at a future time. The AV can determine a ranking for each of the sets of mechanical operations, including a first ranked set and at least one second ranked set. Client or user selection can be given a certain score, weight, or other value. The AV can apply the value to the second ranked set to determine an adjusted ranking. If the adjusted ranking outranks a ranking of the first ranked set, then the AV can expose the first ranked set and the second ranked set to a client interface. If the AV receives a selection of the second ranked set, the AV can perform that set of mechanical operations. Otherwise, the AV can perform the first ranked set of mechanical operations.
