Abstract: Systems and methods for vehicles to detect roadside shelters that can protect users from exposure to various weather conditions. Roadside shelter information can be mapped and added to a mapping database. Systems and methods are provided for live autonomous vehicle perception of viable shelters via machine learning. Shelter information can be incorporated into autonomous vehicle logic and decision-making for user pick-up, drop-off, delivery access, and any other user vehicle access. A user may prefer to wait for a vehicle underneath an awning or inside a bus stop shelter to avoid exposure to inclement weather. Vehicle sensors can be used for perception of roadside features.

Abstract: Micro-authorization of remote assistance for an autonomous vehicle is described herein. A constraint that inhibits propulsion by a mechanical system of the autonomous vehicle is activated by a computing system of the autonomous vehicle, wherein a signal that identifies the activated constraint is transmitted from the autonomous vehicle to a remote computing system. The remote computing system generates instructions to deactivate the activated constraint. A return signal is transmitted from the remote computing system that specifies instructions to deactivate the constraint and a distance to desirably advance the autonomous vehicle. The computing system of the autonomous vehicle deactivates the constraint and the mechanical system is controlled to advance the autonomous vehicle when signal latency is less than a predetermined threshold duration of time.

Abstract: A free space estimation and visualization system for a host vehicle includes a camera configured to collect red-green-blue (“RGB”)-polarimetric image data of drive environs of the host vehicle, including a potential driving path. An electronic control unit (“ECU”) receives the RGB-polarimetric image data and estimates free space in the driving path by processing the RGB-polarimetric image data via a run-time neural network. Control actions are taken in response to the estimated free space. A method for use with the visualization system includes collecting RGB and lidar data of target drive scenes and generating, via a first neural network, pseudo-labels of the scenes. The method includes collecting RGB-polarimetric data via a camera and thereafter training a second neural network using the RGB-polarimetric data and pseudo-labels. The second neural network is used in the ECU to estimate free space in the potential driving path.
