The following detailed description of non-limiting embodiments refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.
In some non-limiting embodiments, an autonomous vehicle (AV) map of a geographic location is used for routing an AV on roadways specified in the AV map. For example, a route including one or more AV lanes on one or more roadway segments is determined for the AV between a pick-up location (or a current location) and a destination location based on the AV map. As an example, the AV travels autonomously (e.g., in a fully-autonomous mode) in the one or more AV lanes on the one or more roadway segments between the pick-up location (or the current location) and the destination location.
However, an AV map (e.g., an AV map, one or more submaps of an AV map, etc.) may not include lanes on roadway segments over which an AV can be operated, routed, and/or travel in or under a partially-autonomous mode or a manual mode (e.g., lanes on roadway segments over which an AV cannot be operated, routed, and/or travel in or under the fully-autonomous mode). For example, the AV may not be allowed to operate (e.g., route, travel, and/or perform one or more functionalities associated with the fully-autonomous mode, such as, functionalities associated with fully-autonomous operation of the AV performed during fully-autonomous operation and/or travel of the AV, etc.) over roadway segments over which the AV cannot operate in or under the fully-autonomous mode in AV lanes based on the AV map (e.g., over which the AV cannot travel and/or be routed to travel fully-autonomously in AV lanes based on the AV map). Additionally, or alternatively, lanes and/or roadway segments over which the AV cannot operate in or under the fully-autonomous mode based on the AV map may be removed from and/or not included in the AV map. In this way, an AV map may be less complete and/or result in less efficient processing for operating the AV (e.g., for routing the AV, controlling travel of the AV, and/or performing one or more functionalities of the AV, etc.). In addition, an AV may have fewer operating options (e.g., fewer options for routing the AV, controlling travel of the AV, and/or performing one or more functionalities of the AV, etc.), may experience processing delays associated with communications (e.g., for receiving additional routing data, etc.), and/or may implement additional processing functions to modify or augment the AV map for non-autonomous routing.
As disclosed herein, in some non-limiting embodiments, a map generation system receives AV map data associated with an AV map of a geographic location and coverage map data associated with a coverage map of the geographic location, and the map generation system generates a hybrid map of the geographic location based on the AV map data and the coverage map data. The map generation system provides hybrid map data associated with the hybrid map for routing of an AV. In this way, the map generation system generates and/or provides a hybrid map of the geographic location that includes an AV lane over which the AV can operate in or under a fully-autonomous mode (e.g., over which the AV can be routed for fully-autonomous travel) linked to a coverage lane over which the AV can operate in or under a partially-autonomous mode or a manual mode (e.g., over which the AV can be routed for partially-autonomous or manual travel). Accordingly, the map generation system generates a more complete map for AV routing that enables more efficient processing for operating the AV and provides more roadway options for routing the AV.
As disclosed herein, in some non-limiting embodiments, a vehicle computing system of an AV receives hybrid map data associated with a hybrid map of a geographic location and determines a route including an AV lane linked with a coverage lane of a roadway in a geographic location based on the hybrid map data. The hybrid map includes the AV lane linked with the coverage lane of the roadway in the geographic location. The hybrid map data is associated with an indication that the AV can operate under a fully-autonomous mode in the AV lane on the roadway and an indication that the AV can operate under a partially-autonomous mode or a manual mode in the coverage lane on the roadway. In this way, the vehicle computing system determines a route that enables both operation in or under the fully-autonomous mode (e.g., fully-autonomous travel and/or routing for fully-autonomous travel based on an AV lane) and operation in or under the partially-autonomous mode or the manual mode (e.g., partially-autonomous travel or manual travel and/or routing for partially-autonomous travel or manual travel based on a coverage lane) of the AV traveling on the route. Accordingly, the hybrid map enables the vehicle computing system to generate a route in a more efficient manner with less processing delays and/or routing for the AV to be performed by the vehicle processing system (e.g., completely by the vehicle processing system).
In some non-limiting embodiments, a functionality associated with the fully-autonomous mode (e.g., with fully-autonomous operation of the AV performed during fully-autonomous travel of the AV) is not performed in the partially-autonomous mode or the manual mode (e.g., during partially-autonomous or manual, non-autonomous travel of the AV). For example, some functionalities associated with the fully-autonomous mode and/or systems associated with control of fully-autonomous travel of the AV in the fully-autonomous mode may not be performed during travel of the AV in the partially-autonomous mode or the manual mode. As an example, higher resolution localization operations and/or systems, such as localization based on LIDAR point clouds and/or precise pose positioning, may not be available for travel of the AV in a coverage lane in the partially-autonomous mode or the manual mode, for example, because coverage data associated with the coverage lane may not provide a sufficient level of detail or resolution to implement the higher resolution localization operations and/or systems.

In some non-limiting embodiments, vehicle computing system 202 is connected to or includes positioning system 204. In some non-limiting embodiments, positioning system 204 determines a position (e.g., a current position, a past position, etc.) of autonomous vehicle 104. In some non-limiting embodiments, positioning system 204 determines a position of autonomous vehicle 104 based on an inertial sensor, a satellite positioning system, an IP address (e.g., an IP address of autonomous vehicle 104, an IP address of a device in autonomous vehicle 104, etc.), triangulation based on network components (e.g., network access points, cellular towers, Wi-Fi access points, etc.), and/or proximity to network components, and/or the like. In some non-limiting embodiments, the position of autonomous vehicle 104 is used by vehicle computing system 202.
In some non-limiting embodiments, vehicle computing system 202 receives sensor data from one or more sensors 206 that are coupled to or otherwise included in autonomous vehicle 104. For example, one or more sensors 206 includes a Light Detection and Ranging (LIDAR) system, a Radio Detection and Ranging (RADAR) system, one or more cameras (e.g., visible spectrum cameras, infrared cameras, etc.), and/or the like. In some non-limiting embodiments, the sensor data includes data that describes a location of objects within the surrounding environment of the autonomous vehicle 104. In some non-limiting embodiments, one or more sensors 206 collect sensor data that includes data that describes a location (e.g., in three-dimensional space relative to the autonomous vehicle 104) of points that correspond to objects within the surrounding environment of autonomous vehicle 104.
In some non-limiting embodiments, the sensor data includes a location (e.g., a location in three-dimensional space relative to the LIDAR system) of a number of points (e.g., a point cloud) that correspond to objects that have reflected a ranging laser. In some non-limiting embodiments, the LIDAR system measures distances by measuring a Time of Flight (TOF) that a short laser pulse takes to travel from a sensor of the LIDAR system to an object and back, and the LIDAR system calculates the distance of the object to the LIDAR system based on the known speed of light. In some non-limiting embodiments, map data includes LIDAR point cloud maps associated with a geographic location (e.g., a location in three-dimensional space relative to the LIDAR system of a mapping vehicle) of a number of points (e.g., a point cloud) that correspond to objects that have reflected a ranging laser of one or more mapping vehicles at the geographic location. As an example, a map can include a LIDAR point cloud layer that represents objects and distances between objects in the geographic location of the map.
In some non-limiting embodiments, the sensor data includes a location (e.g., a location in three-dimensional space relative to the RADAR system) of a number of points that correspond to objects that have reflected a ranging radio wave. In some non-limiting embodiments, radio waves (e.g., pulsed radio waves or continuous radio waves) transmitted by the RADAR system can reflect off an object and return to a receiver of the RADAR system. The RADAR system can then determine information about the object's location and/or speed. In some non-limiting embodiments, the RADAR system provides information about the location and/or the speed of an object relative to the RADAR system based on the radio waves.
In some non-limiting embodiments, image processing techniques (e.g., range imaging techniques such as, for example, structure from motion, structured light, stereo triangulation, etc.) can be performed by system 200 to identify a location (e.g., in three-dimensional space relative to the one or more cameras) of a number of points that correspond to objects that are depicted in images captured by one or more cameras. Other sensors can identify the location of points that correspond to objects as well.
In some non-limiting embodiments, map database 208 provides detailed information associated with the map, features of the roadway in the geographic location, and information about the surrounding environment of the autonomous vehicle 104 for the autonomous vehicle to use while driving (e.g. traversing a route, planning a route, determining a motion plan, controlling the autonomous vehicle, etc.).
In some non-limiting embodiments, vehicle computing system 202 receives a vehicle pose from localization system 210 based on one or more sensors 206 that are coupled to or otherwise included in autonomous vehicle 104. In some non-limiting embodiments, the localization system 210 includes a LIDAR localizer, a low quality pose localizer, and/or a pose filter. For example, the localization system uses a pose filter that receives and/or determines one or more valid pose estimates (e.g. not based on invalid position data, etc.) from the LIDAR localizer and/or the low quality pose localizer, for determining a map-relative vehicle pose. For example, low quality pose localizer determines a low quality pose estimate in response to receiving position data from positioning system 204 for operating (e.g., routing, navigating, controlling, etc.) the autonomous vehicle 104 under manual control (e.g. in a coverage lane). In some non-limiting embodiments, LIDAR localizer determines a LIDAR pose estimate in response to receiving sensor data (e.g. LIDAR data, RADAR data, etc.) from sensors 206 for operating (e.g., routing, navigating, controlling, etc.) the autonomous vehicle 104 under autonomous control (e.g. in an AV lane).
In some non-limiting embodiments vehicle command system 212 includes vehicle commander system 214, navigator system 216, and lane associator system 218 that cooperate to route and/or navigate the autonomous vehicle 104 in a geographic location. In some non-limiting embodiments, vehicle commander system 214 provides tracking of a current objective of the autonomous vehicle 104, including a current service, a target pose, and/or a coverage plan (e.g. development testing, etc.). In some non-limiting embodiments, navigator system 216 determines and/or provides a route plan for the autonomous vehicle 104 based on the current state of the autonomous vehicle 104, map data (e.g. lane graph, etc.), and one or more vehicle commands (e.g. a target pose). For example, navigator system 216 determines a route plan (e.g., plan, re-plan, deviation, etc.) including one or more lanes (e.g., current lane, future lane, etc.) in one or more roadways that the autonomous vehicle 104 may traverse on a route to a destination (e.g. target, trip drop-off, etc.).
In some non-limiting embodiments, navigator system 216 determines a route plan based on one or more lanes received from lane associator system 218. In some non-limiting embodiments, lane associator system 218 determines one or more lanes of a route in response to receiving a vehicle pose from the localization system 210. For example, the lane associator system 218 determines, based on the vehicle pose, that the AV is on a coverage lane, and in response to determining that the AV is on the coverage lane, determines one or more candidate lanes (e.g. routable lanes) within a distance of the vehicle pose associated with the autonomous vehicle 104. For example, the lane associator system 218 determines, based on the vehicle pose, that the AV is on an AV lane, and in response to determining that the AV is on the AV lane, determines one or more candidate lanes (e.g. routable lanes) within a distance of the vehicle pose associated with the autonomous vehicle 104. In some non-limiting embodiments, navigator system 216 generates a cost function for each of one or more candidate lanes the autonomous vehicle 104 may traverse on a route to a destination. For example, navigator system 216 generates the cost function that describes a cost (e.g., a cost over a time period) of following (e.g., adhering to) one or more lanes that may be used to reach a target pose.
In some non-limiting embodiments, perception system 220 detects and/or tracks objects (e.g., vehicles, pedestrians, bicycles, and the like) that are proximate to (e.g., in proximity to the surrounding environment of) the autonomous vehicle 104 over a time period. In some non-limiting embodiments, perception system 220 can retrieve (e.g., obtain) map data from map database 208 that provides detailed information about the surrounding environment of the autonomous vehicle 104.
In some non-limiting embodiments, perception system 220 determines one or more objects that are proximate to autonomous vehicle 104 based on sensor data received from one or more sensors 206 and/or map data from map database 208. For example, perception system 220 determines, for the one or more objects that are proximate, state data associated with a state of such object. In some non-limiting embodiments, the state data associated with an object includes data associated with a location of the object (e.g., a position, a current position, an estimated position, etc.), data associated with a speed of the object (e.g., a magnitude of velocity of the object), data associated with a direction of travel of the object (e.g., a heading, a current heading, etc.), data associated with an acceleration rate of the object (e.g., an estimated acceleration rate of the object, etc.), data associated with an orientation of the object (e.g., a current orientation, etc.), data associated with a size of the object (e.g., a size of the object as represented by a bounding shape such as a bounding polygon or polyhedron, a footprint of the object, etc.), data associated with a type of the object (e.g., a class of the object, an object with a type of vehicle, an object with a type of pedestrian, an object with a type of bicycle, etc.), and/or the like.
In some non-limiting embodiments, perception system 220 determines state data for an object over a number of iterations of determining state data. For example, perception system 220 updates the state data for each object of a plurality of objects during each iteration.
In some non-limiting embodiments, prediction system 222 receives the state data associated with one or more objects from perception system 220. Prediction system 222 predicts one or more future locations for the one or more objects based on the state data. For example, prediction system 222 predicts the future location of each object of a plurality of objects within a time period (e.g., 5 seconds, 10 seconds, 20 seconds, etc.). In some non-limiting embodiments, prediction system 222 predicts that an object will adhere to the object's direction of travel according to the speed of the object. In some non-limiting embodiments, prediction system 222 uses machine learning techniques or modeling techniques to make a prediction based on state data associated with an object.
In some non-limiting embodiments, motion planning system 224 determines a motion plan for autonomous vehicle 104 based on a prediction of a location associated with an object provided by prediction system 222 and/or based on state data associated with the object provided by perception system 220. For example, motion planning system 224 determines a motion plan (e.g., an optimized motion plan) for the autonomous vehicle 104 that causes autonomous vehicle 104 to travel relative to the object based on the prediction of the location for the object provided by prediction system 222 and/or the state data associated with the object provided by perception system 220.
In some non-limiting embodiments, motion planning system 224 receives a route plan as a command from the navigator system 216. In some non-limiting embodiments, motion planning system 224 determines a cost function for each of one or more motion plans of a route for autonomous vehicle 104 based on the locations and/or predicted locations of one or more objects. For example, motion planning system 224 determines the cost function that describes a cost (e.g., a cost over a time period) of following (e.g., adhering to) a motion plan (e.g., a selected motion plan, an optimized motion plan, etc.). In some non-limiting embodiments, the cost associated with the cost function increases and/or decreases based on autonomous vehicle 104 deviating from a motion plan (e.g., a selected motion plan, an optimized motion plan, a preferred motion plan, etc.). For example, the cost associated with the cost function increases and/or decreases based on autonomous vehicle 104 deviating from the motion plan to avoid a collision with an object.
In some non-limiting embodiments, motion planning system 224 determines a cost of following a motion plan. For example, motion planning system 224 determines a motion plan for autonomous vehicle 104 based on one or more cost functions. In some non-limiting embodiments, motion planning system 224 determines a motion plan (e.g., a selected motion plan, an optimized motion plan, a preferred motion plan, etc.) that minimizes a cost function. In some non-limiting embodiments, motion planning system 224 provides a motion plan to vehicle controls 226 (e.g., a device that controls acceleration, a device that controls steering, a device that controls braking, an actuator that controls gas flow, etc.) to implement the motion plan.

In some non-limiting embodiments, a map of a geographic location includes one or more routes that include one or more roadways.
In some non-limiting embodiments, a road refers to a paved or otherwise improved path between two places that allows for travel by a vehicle (e.g., autonomous vehicle 104). Additionally, or alternatively, a road includes a roadway and a sidewalk in proximity to (e.g., adjacent, near, next to, touching, etc.) the roadway. In some non-limiting embodiments, a roadway includes a portion of road on which a vehicle is intended to travel and is not restricted by a physical barrier or by separation so that the vehicle is able to travel laterally. Additionally, or alternatively, a roadway (e.g., one or more roadway segments) includes one or more lanes, such as a travel lane (e.g., a lane upon which a vehicle travels, a traffic lane, etc.), a parking lane (e.g., a lane in which a vehicle parks), a bicycle lane (e.g., a lane in which a bicycle travels), a turning lane (e.g., a lane in which a vehicle turns from), and/or the like. In some non-limiting embodiments, a roadway is connected to another roadway, for example a lane of a roadway is connected to another lane of the roadway and/or a lane of the roadway is connected to a lane of another roadway.
In some non-limiting embodiments, a roadway is associated with map data (e.g., map data, AV map data, coverage map data, hybrid map data, submap data, etc.) that defines one or more attributes of (e.g., metadata associated with) the roadway (e.g., attributes of a roadway in a geographic location, attributes of a segment of a roadway, attributes of a lane of a roadway, etc.). In some non-limiting embodiments, an attribute of a roadway includes a road edge of a road (e.g., a location of a road edge of a road, a distance of location from a road edge of a road, an indication whether a location is within a road edge of a road, etc.), an intersection, connection, or link of a road with another road, a roadway of a road, a distance of a roadway from another roadway (e.g., a distance of an end of a lane and/or a roadway segment or extent to an end of another lane and/or an end of another roadway segment or extent, etc.), a lane of a roadway of a road (e.g., a travel lane of a roadway, a parking lane of a roadway, a turning lane of a roadway, lane markings, a direction of travel in a lane of a roadway, etc.), one or more objects (e.g., a vehicle, vegetation, a pedestrian, a structure, a building, a sign, a lamppost, signage, a traffic sign, a bicycle, a railway track, a hazardous object, etc.) in proximity to and/or within a road (e.g., objects in proximity to the road edges of a road and/or within the road edges of a road), a sidewalk of a road, and/or the like. In some non-limiting embodiments, an attribute of a roadway includes one or more features of the roadway associated with one or more traversals of the roadway by one or more AVs, a number of traversals of the roadway by one or more AVs, a number of interventions associated with one or more traversals of the roadway by one or more AVs, a number of objects (e.g., a number of hazards, a number of bicycles, a railway track in proximity to the roadway, etc.) associated with one or more traversals of the roadway by one or more AVs, a distance (e.g., an average distance, a mile, etc.) associated with one or more traversals of the roadway by one or more AVs (e.g., a distance until a detection of a hazardous event, a distance until detection of a potentially harmful or a harmful event to an AV, to a rider of the AV, to a pedestrian, a distance between a first detection of a hazardous event and a second detection of a hazardous event, miles per harmful event, etc.), one or more traffic controls of the roadway associated with one or more traversals of the roadway by one or more AVs, one or more aspects of the roadway (e.g., a dimension of one or more lanes of the roadway, a width of one or more lanes of the roadway, a number of bicycle lanes of the roadway, etc.) associated with one or more traversals of the roadway by one or more AVs, a speed of one or more AVs associated with one or more traversals of the roadway by the one or more AVs, and/or the like.
In some non-limiting embodiments, a roadway is associated with map data that defines one or more roadway segments or extents of the roadway. For example, a roadway segment or extent can be connected or linked to another roadway segment or extent to form a roadway network, or a roadway network can be divided into roadways segments or extents. In some non-limiting embodiments, a roadway segment or extent is associated with one or more lanes (e.g., one or more AV lanes, one or more coverage lanes, one or more hybrid lanes, etc.), and the one or more lanes are associated with a directional indicator indicating a direction of travel in the one or more lanes of the roadway segment or extent. As an example,
In some non-limiting embodiments, a lane (and/or a roadway segment or extent) includes one or more ends. For example, an end of a lane (and/or a roadway segment or extent) is associated with or corresponds to a geographic location at which map data associated with the lane (and/or the roadway segment or extent) is unavailable. As an example, an end of an AV lane can correspond to a geographic location at which AV map data for that lane ends, for example, a geographic location at which the AV map data associated with the AV lane of a roadway segment extent transitions to coverage map data associated with a coverage lane of the roadway segment (or a geographic location at which less detailed AV map data or no AV map data for the roadway segment exists). In some non-limiting embodiments, for example, as shown in
In some non-limiting embodiments, the map data includes a link (e.g., a logical link) that connects or links a lane (and/or a roadway segment or extent) to another lane (and/or to another roadway segment or extent). As an example, the map data includes a unique identifier for each lane (and/or roadway segment or extent), and the unique identifiers are associated with one another in the map data to indicate a connection or link of a lane to another lane (or a connection or link of a roadway segment or extent to another roadway segment or extent). For example, the unique identifiers can be associated with one another in the map data to indicate that a lane (and/or a roadway segment or extent) is a predecessor lane or a successor lane to another lane (and/or a predecessor or successor roadway segment or extent to another roadway segment or extent). As an example, a direction of travel of a predecessor lane to another lane is from the predecessor lane to the another lane, and a direction of travel of a successor lane to another lane is from the another lane to the successor lane. In some non-limiting embodiments, a distance between ends of an AV lane in an AV map linked to another AV lane in the AV map satisfies a threshold distance. For example, an end of an AV lane in an AV map can be linked to another lane in the AV map if the distance between the ends satisfies the threshold distance. As an example, the threshold distance to be satisfied for linking AV lanes in an AV map can be a shorter distance than a threshold distance to be satisfied for linking coverage lanes in a coverage map or linking an AV lane to a coverage lane in a hybrid map.
In some non-limiting embodiments, a map includes one or more AV lanes and/or one or more coverage lanes. In some non-limiting embodiments, a map includes one or more AV maps or submaps including one or more AV lanes and/or one or more coverage maps or submaps including one or more coverage lanes. In some non-limiting embodiments, AV map data is associated with an AV lane of a roadway in a geographic location, and coverage map data is associated with a coverage map of the geographic location. In some non-limiting embodiments, a map (e.g., a hybrid map) includes the AV lane linked with the coverage lane of the roadway in the geographic location.
In some non-limiting embodiments, the AV map data is associated with an AV lane of a roadway in the geographic location, and the coverage map data is associated with a coverage lane of the roadway in the geographic location. In some non-limiting embodiments, the AV map data is associated with an indication that the autonomous vehicle 104 can operate in the AV lane under a fully-autonomous mode, and the coverage map data is associated with an indication that the autonomous vehicle 104 can operate in the coverage lane under a partially-autonomous mode or a manual mode. For example, the AV map data is associated with an indication of whether autonomous vehicle 104 can be operated, routed, and/or travel in or under a fully-autonomous mode (e.g., be routed to travel fully-autonomously and/or travel fully-autonomously) in AV lanes, and the coverage map data is associated with an indication of whether autonomous vehicle 104 can be operated, routed, and/or travel in or under a partially-autonomous mode or a manual mode (e.g., be routed to travel partially-autonomously or manually and/or travel partially-autonomously or manually). As an example, the AV map includes a plurality of lanes, the plurality of lanes including the AV lane linked to another AV lane, and the AV map data is associated with an indication of whether autonomous vehicle 104 can operate under the fully-autonomous mode in the plurality of AV lanes. In some non-limiting embodiments, the coverage map data is associated with an indication that autonomous vehicle 104 cannot be operated, routed, and/or travel in or under the fully-autonomous mode in coverage lanes. As an example, the coverage map includes a plurality of lanes, the plurality of lanes including the coverage lane linked to another coverage lane, and the coverage map data is associated with an indication of whether autonomous vehicle 104 can operate under the partially-autonomous mode or the manual mode in the plurality of coverage lanes.
In some non-limiting embodiments, a lane in which autonomous vehicle 104 can operate under the fully-autonomous mode is associated with additional and/or alternative map data (e.g., additional or alternative attributes and/or roadway features) than another lane in which autonomous vehicle 104 cannot operate under the fully-autonomous mode. As an example, an AV lane in which autonomous vehicle 104 can operate under the fully-autonomous mode can be associated with AV map data including a more detailed and/or higher resolution map (e.g., a higher resolution point cloud), and a coverage lane in which autonomous vehicle 104 cannot operate under the fully-autonomous mode can be associated with coverage map data including a less detailed and/or lower resolution map (e.g., a lower resolution point cloud or no point cloud).
As further shown in
In some non-limiting embodiments, generating the hybrid map includes modifying the AV map to unlink the AV lane and another lane in the AV map based on the indication. For example, the map generation system 102 removes the another lane from the AV map based on an indication that autonomous vehicle 104 cannot be operated, routed, and/or travel in or under the fully-autonomous mode in the another lane. As an example, the map generation system 102 determines that the autonomous vehicle 104 cannot be operated, routed, and/or travel in or under the fully-autonomous mode in the another lane in the AV map based on the map data and/or user input. In some non-limiting embodiments, the map generation system 102 compares a distance between an end of the AV lane and an end of the another lane in the AV map to a threshold distance and removes the another lane from the AV map and/or unlinks the another lane from the AV lane in the AV map based on the comparison. For example, if a distance between an end of the AV lane in the AV map that is linked to the another lane in the AV map fails to satisfy a threshold distance, the map generation system 102 removes the another lane from the AV map and/or unlinks the another lane from the AV lane in the map.

In some non-limiting embodiments, map generation system 102 can analyze each AV lane of the AV map (or a subset of AV lanes of the AV map) for an end of that AV lane that is not linked to another AV lane in the AV map based on the map data and generate links to coverage lanes for unlinked ends of unlinked AV lanes as described herein. In some non-limiting embodiments, map generation system 102 can determine the subset of AV lanes of the AV map to analyze for unlinked ends based on one or more attributes of the AV lanes, user input, and/or the like.

In some non-limiting embodiments, generating the link includes generating a hybrid lane between the unlinked AV lane and the coverage lane. In some non-limiting embodiments, a hybrid lane can be associated with coverage map data and may be represented by and/or include a coverage lane for operating, routing, and/or traveling functions of autonomous vehicle 104. For example, map generation system 102 generates a hybrid lane (e.g., coverage lane) between the unlinked AV lane and the coverage lane to be included in the hybrid map. As an example, the route includes the unlinked AV lane linked to the hybrid lane and the hybrid lane linked to the coverage lane. In some non-limiting embodiments, if the distance between the unlinked end of the unlinked AV lane and the end of the determined coverage lane at or nearest to the unlinked end of the unlinked AV lane does not satisfy the threshold distance (e.g., is greater than the threshold distance, etc.), generating the link includes generating the hybrid lane between the unlinked end of the unlinked AV lane and the end of the determined coverage lane at or nearest to the unlinked end of the AV lane to be included in the hybrid map. For example, the hybrid lane includes a first end linking the unlinked end of the unlinked AV lane and a second end linking the end of the coverage lane. As an example, map generation system 102 generates a unique identifier for the hybrid lane, associates the unique identifier of the unlinked AV lane as a predecessor or successor lane to the hybrid lane in the hybrid map data, and associates the unique identifier of the determined coverage lane as the other of the predecessor or successor lane to the hybrid lane in the hybrid map data. In some non-limiting embodiments, the hybrid map data is associated with an indication that the autonomous vehicle 104 can operate in the hybrid lane under the partially-autonomous mode or the manual mode. For example, map generation system 102 generates hybrid map data associated with the hybrid lane based on the AV map data and the coverage map data. As an example, map generation system 102 determines, based on the AV map data and the coverage map data, hybrid map data associated with one or more attributes of the hybrid lane, such as, a directional indicator of the hybrid lane, connections or links of the hybrid lane to the AV lane and the coverage lane, an association of the hybrid lane with one or more roadway segments or extents that connect the AV lane and the coverage lane, and/or the like. In some non-limiting embodiments, map generation system 102 extrapolates the AV map data of the unlinked AV lane and the coverage map data of the determined coverage lane to estimate one or more attributes of the hybrid lane between the unlinked AV lane and the determined coverage lane. For example, one or more attributes of the hybrid lane (e.g., lane dimensions of the hybrid lane, etc.) between the unlinked AV lane and the determined coverage lane can be estimated to fit the hybrid lane between the unlinked AV lane and the determined coverage lane in the hybrid map (e.g., to fit dimensions of the hybrid lane to the dimensions of the unlinked AV lane and the determined coverage lane, etc.).

In some non-limiting embodiments, autonomous vehicle 104 includes sensors 206 for detecting an object in an environment surrounding the AV as described herein, and vehicle computing system 202 controls travel of autonomous vehicle 104 on at least a portion of the route based on sensor data from sensors 206 and the hybrid map data associated with the hybrid map. For example, vehicle computing system 202 controls one or more vehicle controls 226 (e.g., a device that controls acceleration, a device that controls steering, a device that controls braking, an actuator that controls gas flow, etc.) of autonomous vehicle 104 based on the sensor data and the hybrid map data to control travel of the autonomous vehicle 104 on the route under the fully-autonomous mode.
In some non-limiting embodiments, autonomous vehicle 104 includes positioning system 204 for determining a position of autonomous vehicle 104 as described herein, and vehicle computing system 202 controls autonomous vehicle 104 to operate under the fully-autonomous mode on the at least a portion of the route and controls autonomous vehicle 104 to operate under the partially-autonomous mode or the manual mode on at least another portion of the route based on positioning data from positioning system 204 and the hybrid map data associated with the hybrid map. For example, vehicle computing system 202 determines a position of autonomous vehicle 104 in the AV lane or the coverage lane (e.g., the hybrid lane), and controls autonomous vehicle 104 to operate based on the location of autonomous vehicle 104 (e.g., based on a type of lane in which autonomous vehicle 104 is located, based on a location of autonomous vehicle 104 with respect to an end of the lane in which autonomous vehicle 104 is located, based on a type of predecessor lane and/or successor lane of the lane in which autonomous vehicle 104 is located, etc.) As an example, vehicle computing system 202 controls one or more vehicle controls 226 (e.g., a device that controls acceleration, a device that controls steering, a device that controls braking, an actuator that controls gas flow, etc.) of autonomous vehicle 104 based on the positioning data and the hybrid map data to operate the autonomous vehicle 104 in or under the fully-autonomous mode in the AV lane, and vehicle computing system 202 controls one or more functionalities associated with the partially-autonomous mode or the manual mode of autonomous vehicle 104 based on the positioning data and the hybrid map data to operate the autonomous vehicle 104 in or under the partially-autonomous mode or the manual mode in the coverage lane (or the hybrid lane).
In some non-limiting embodiments, vehicle computing system 202 determines, based on the positioning data from the positioning system and the hybrid map data, that autonomous vehicle 104 is operating under the fully-autonomous mode in the AV lane on the route including the AV lane linked to the coverage lane, and vehicle computing system 202 controls autonomous vehicle 104 to switch from operating under the fully-autonomous mode to operating under the partially-autonomous mode or the manual mode in the AV lane based on determining that autonomous vehicle 104 is operating under the fully-autonomous mode in the AV lane. For example, vehicle computing system 202 can determine based on the positioning data and the hybrid map data that autonomous vehicle 104 is about to enter the coverage lane (or the hybrid lane) from the AV lane (e.g., that autonomous vehicle 104 is traveling on the AV lane in a direction toward a successor lane (e.g., the coverage lane or the hybrid lane) and is within a threshold distance of a location of the connection or link between the AV lane and the successor lane. As an example, vehicle computing system 202 can control autonomous vehicle 104 to switch or begin the transition from operating under the fully-autonomous mode to operating under the partially-autonomous mode or the manual mode in the AV lane before autonomous vehicle 104 enters the coverage lane (or the hybrid lane).

In some non-limiting embodiments, the hybrid map enables vehicle computing system 712 to use additional and/or alternative routes for routing autonomous vehicle 704 other than routes that are available for routing from the AV map, and vehicle computing system 712 can perform all routing (e.g., routing for travel under fully-autonomous mode, partially-autonomous mode, manual mode, etc.) at autonomous vehicle 704 without some or all of the routing for autonomous vehicle 704 being performed at map generation system 702 or another remote system. For example, the hybrid map enables vehicle computing system 712 to autonomously determine a route between the pick-up location (or the current location) and the drop-off location in the geographic location that includes the AV lane linked with the coverage lane based on the hybrid map data, without requiring routing to be performed at map generation system 702 or another remote system to route autonomous vehicle 704 for travel in or under the partially-autonomous mode or the manual mode on a route that also includes travel in or under the fully-autonomous mode.
