Detecting And Responding To Emergency Vehicles In A Roadway
The present invention extends to methods, systems, and computer program products for detecting and responding to emergency vehicles in a roadway. Aspects of the invention can be used to detect emergency vehicles and properly yield to emergency vehicles depending on roadway configuration. A vehicle includes a plurality of sensors. The vehicle also includes vehicle to vehicle (V2V) communication capabilities and has access to map data. Sensor data from the plurality of sensors along with map data is provided as input to a neural network (either in the vehicle or in the cloud). Based on sensor data, the neural network detects when one or more emergency vehicles are approaching the vehicle. From a roadway configuration, a vehicle can use the plurality of sensors to automatically (and safely) yield to detected emergency vehicle(s). Automatically yielding can include one or more of: slowing down, changing lanes, stopping, etc.

- 1. At a vehicle, a method for yielding to an emergency vehicle comprising:
accessing sensor data from a plurality of sensors at the vehicle; detect that the emergency vehicle is approaching the vehicle on a roadway based on the accessed sensor data; determining a yield strategy for the vehicle to yield to the emergency vehicle based on additional sensor data; and automatically controlling vehicle components to cause the vehicle to implement the yield strategy.
- 7. A vehicle comprising:
one or more processors; system memory coupled to one or more processors, the system memory storing instructions that are executable by the one or more processors; a plurality of sensors for sensing an external environment in the vicinity of the vehicle; the one or more processors configured to execute the instructions stored in the system memory to yield to an emergency vehicle, including the following:
access sensor data from one or more of the plurality of sensors;
determine that the emergency vehicle is approaching the vehicle on a roadway based on the accessed sensor data;
access additional sensor data from another one or more of the plurality of sensors;
determine a yield strategy for the vehicle to yield to the emergency vehicle based on the additional sensor data; and
receive adjustments to vehicle component configurations to cause the vehicle to implement the yield strategy.
- 16. A computer program product for use at an autonomous vehicle, the computer program product for implementing a method for yielding to an emergency vehicle, the computer program product comprising one or more computer storage devices having stored thereon computer-executable instructions that, when executed by a processor, cause the vehicle to perform the method including the following:
access sensor data from one or more of a plurality of sensors, the plurality of sensors for sensing the external environment in the vicinity of the autonomous vehicle; determine that the emergency vehicle is approaching the vehicle on a roadway based on the accessed sensor data; access additional sensor data from an additional one or more of the plurality of sensors; determine a yield strategy for the vehicle to yield to the emergency vehicle based on the additional sensor data; and automatically adjust vehicle component configurations to cause the vehicle to implement the yield strategy.
