Abstract
This disclosure relates to a method of safely and automatically navigating in the presence of emergency vehicles. A first vehicle may receive, via communication hardware, a message indicating presence of the emergency vehicle. Such a message may originate from the emergency vehicle itself and/or from infrastructure such as a smart traffic light that can sense the presence of the emergency vehicle. The first vehicle may then determine the relative location of the emergency vehicle and automatically respond appropriately by determining a safe trajectory and navigating according to that trajectory until the emergency vehicle is out of range. In some examples, the first vehicle may detect the presence of an emergency vehicle using on-board sensors such as distance measuring sensors, depth sensors, and cameras, in addition to receiving a message via communication hardware.
