Abstract
A controlled vehicle is provided that detects the presence of an emergency vehicle by monitoring the trajectories of vehicles that are sharing the road with the controlled vehicle. The controlled vehicle may determine that the trajectory of each of the monitored vehicles follows the same predetermined pattern. Based on detecting the predetermined pattern in the behavior of the monitored vehicles, the controlled vehicle may deduce that an emergency vehicle is present in the vicinity of the monitored vehicles and/or the controlled vehicle.
Claims21
A method comprising:
- identifying a first vehicle that is travelling on a same road as a controlled vehicle;
- identifying a second vehicle that is travelling on the same road as the controlled vehicle;
- tracking the first vehicle to determine a first trajectory of the first vehicle;
- tracking the second vehicle to determine a second trajectory of the second vehicle;
- comparing, by a processor, the first trajectory to the second trajectory to determine whether the first trajectory and the second trajectory match, wherein two trajectories match when both have a similar shape;
- determining, based on a match between the first trajectory and the second trajectory, that an emergency vehicle is present on the road;
- changing a state of a vehicle system of the controlled vehicle in response to determining that the emergency vehicle is present on the road.

A method comprising:
- identifying a first vehicle that is travelling on a same road as the controlled vehicle;
- identifying a second vehicle that is travelling on the same road as the controlled vehicle;
- identifying a first set of one or more actions performed by the first vehicle;
- identifying a second set of one or more actions performed by the second vehicle;
- comparing, by a processor, the first set to the second set to determine whether the first set and the second set match, wherein two sets match when both include similar actions;
- determining, based on a match between the first set and the second set, that an emergency vehicle is present on the road;
- changing a state of a vehicle system of the controlled vehicle in response to determining that the emergency vehicle is present on the road.
4 more elements
A method comprising:
- identifying a plurality of vehicles that share a road with a controlled vehicle;
- monitoring actions performed by each one of the plurality of vehicles;
- and
- identifying a similarity in the actions performed by each one of the plurality of vehicles;
- determining, by a processor, based on the similarity being identified, that an emergency vehicle is present on the road;
- changing a state of a vehicle system of the controlled vehicle in response to determining that the emergency vehicle is present on the road.
