Abstract: An autonomous vehicle is disclosed that includes a velocity sensor; a radar system; a digital storage medium; and a controller in communication with the digital storage medium, radar system, and the velocity sensor. The controller, for example, may retrieve map data from the digital storage medium; receive current radar data from the radar system; receive autonomous vehicle velocity data from the velocity sensor; identify radar data points in the current radar data that represent objects in motion; remove radar data points from the current radar data that represent objects in motion; and/or match the radar data with the map data to return location data.

Abstract: An autonomous vehicle urgent stop system is disclosed. The autonomous vehicle urgent stop system may include one or more vehicle sensors and/or one or more environmental sensors that either part of the autonomous vehicle or separate from the autonomous vehicle sensors. The urgent stop system may map a safe-stop trajectory for the autonomous vehicle based on the trajectory of the autonomous vehicle and environmental data received from an environmental sensor. The safe-stop trajectory ends in the autonomous vehicle being stopped. In response to an emergency trigger event, the urgent stop system may direct the autonomous vehicle to follow the safe-stop trajectory.
