A sheet-shaped magnetic marker (1) to be laid on a road surface so as to be able to be detected by a magnetic sensor attached to a vehicle to achieve assist for driving operation of the vehicle by a driver or control on a vehicle side to achieve automatic driving independently from operation of the driver is divided into a plurality of regions in a matrix shape by a cut line (1C) cutting a magnet sheet (11) and a nonskid layer (181), with an adhesive layer being left. Thus, if peeling partially occurs, a region including the peeled part can be isolated, and expansion of peeling can be prevented.

A target vehicle recognition apparatus detects a stopped vehicle ahead of the host vehicle, detects a reference boundary line position where at least one of two boundary lines forming a travel lane of the host vehicle intersects a reference axis extending from a lower end of the stopped vehicle in an image horizontal direction on a captured image, recognizes the stopped vehicle as a target vehicle of steering control when the reference boundary line position between a vehicle left end position of the stopped vehicle and a vehicle right end position of the stopped vehicle is present, and does not recognize the stopped vehicle as a target vehicle of steering control when the reference boundary line position between the vehicle left end position of the stopped vehicle and the vehicle right end position of the stopped vehicle is not present.

DETERMINATION OF PATH TO VEHICLE STOP LOCATION IN A CLUTTERED ENVIRONMENT

Methods and systems for enabling an autonomous vehicle (AV) to determine a path to a stopping location are disclosed. Upon receipt of a service request, the AV will determine a desired stop location (DSL) and state information for the service request. The AV using the DSL and the state information to define a pickup/drop-off interval that comprises an area of a road that includes the DSL. When approaching the pickup/drop-off interval, the AV will uses its perception system to determine whether an object is occluding the DSL. If no object is occluding the DSL, the AV will continue along the path toward the DSL. However, if an object is occluding the DSL, the AV will identify and move to a non-occluded alternate stop location (ASL) within the pickup/drop-off interval. The ASL must satisfy one or more permissible stopping location criteria.

OVERSIGHT SYSTEM TO AUTONOMOUS VEHICLE COMMUNICATIONS
20220348222 · 2022-11-03 ·

A system comprises an autonomous vehicle (AV) and an operation server operably coupled with the AV. The operation server accesses environmental data associated with a road traveled by the AV. The environmental data is associated with a time window during which the AV is traveling along the road. The operation server compares the environmental data with map data that comprises expected road conditions ahead of the AV. The operation server determines whether the environmental data comprises an unexpected road condition that is not included in the map data. In response to determining that the environmental data comprises the unexpected road condition that is not included in the map data, the operation server determines a location coordinate of the unexpected road condition, and communicates a command to the AV to maneuver to avoid the unexpected road condition.
