Vehicle-based road obstacle identification system

A vehicle comprising:

• a plurality of sensors, wherein a first sensor in the plurality of sensors is configured to generate velocity data, and wherein a second sensor in the plurality of sensors is configured to generate location data;
• and
• a processor configured with computer-executable instructions, wherein the computer-executable instructions, when executed, cause the processor to:
• detect, at a first time instant, a partial vehicle stop at which the vehicle slows by at least a threshold velocity using the generated velocity data;
• determine a location of the vehicle at the first time instant using the generated location data;
• generate a grid map in which information derived from map data and having a first color is laid over information derived from captured sensor data and having a second color;
• determine, by application of the grid map as an input to an artificial intelligence model stored on the vehicle, a scene surrounding the vehicle at the determined location;
• determine, based on at least one of the determined scene or the map data, that a cause of the detected partial vehicle stop is the vehicle arriving at a road feature that vehicles pass without coming to a complete stop;
• and
• cause the map data to be updated to include a virtual partial stop line at the location.

A method implemented by a vehicle, the method comprising:

• detecting, at a first time instant, a partial vehicle stop at which the vehicle slows by at least a threshold velocity using velocity data measured by the vehicle;
• determining a location of the vehicle at the first time instant;
• generating a grid map in which information derived from map data and having a first color is laid over information derived from captured sensor data and having a second color;
• determining, based in part on application of the grid map as an input to an artificial intelligence model running on the vehicle that outputs a scene surrounding the vehicle, that a cause of the detected partial vehicle stop is the vehicle arriving at a road feature that vehicles pass without coming to a complete stop;
• and
• causing the map data to be updated to include a virtual partial stop line at the location.

Non-transitory, computer-readable storage media comprising computer executable instructions for identifying a virtual partial stop line, wherein the computer-executable instructions, when executed by a vehicle, cause the vehicle to:

• detect, at a first time instant, a partial vehicle stop at which the vehicle slows by at least a threshold velocity using velocity data measured by the vehicle;
• determine a location of the vehicle at the first time instant;
• generate a grid map in which information derived from map data and having a first color is laid over information derived from captured sensor data and having a second color;
• determine, based in part on application of the grid map as an input to an artificial intelligence model running on the vehicle that outputs a scene surrounding the vehicle, that a cause of the detected partial vehicle stop is the vehicle arriving at a road feature that vehicles pass without coming to a complete stop;
• and
• cause the map data to be updated to include the virtual partial stop line at the location.
