Abstract: A method for generating an occlusion map using crowdsourcing includes receiving occlusion data from a host vehicle. The occlusion data includes a plurality of virtual detection lines each extending from the sensor and intersecting an off-road area. The method further includes marking all non-occluded points that are located inside the off-road area and that are located within a predetermined distance from each plurality of virtual detection lines. The method further includes determining a non-occluded region inside the off-road area using the non-occluded points that have been previously marked inside the off-road area, wherein the non-occluded region is part of non-occlusion data. The method further includes generating an occlusion map using the non-occlusion data. The method further includes transmitting the occlusion map to the host vehicle. The method can also determine an occlusion caused by an elevation peak.

Abstract: A method for generating a user profile and system including a controller configured to execute instructions to execute the method. The method including determining by a user of a first vehicle that an interactive maneuver is needed to provide a resource, identifying a second vehicle to interact with, contacting a user of the second vehicle, requesting the user of the second vehicle to perform the interactive maneuver, receiving a response from the user of the second vehicle, and generating a user profile for the user of the second vehicle based on the performance of providing the resource.

Abstract: A system comprises a computer including a processor and a memory. The memory includes instructions such that the processor is programmed to: execute an autonomous vehicle algorithm simulating vehicle operations within a simulated environment. The simulated environment represents a plurality of driving situations. The memory also includes instructions such that the processor is programmed to: determine a challenge rating for the driving situation, determine an autonomous vehicle performance assessment score corresponding to the simulated environment, compare the autonomous vehicle performance assessment score with a human driving score corresponding to the simulated environment, and generate a performance profile based on the comparison. In some implementations, a vehicle computer can determine a challenge rating and generate at least one of a driver takeover recommendation or an alert indicating a presence of a fault based on a comparison of vehicle performance with the challenge rating.
