Abstract
Methods and devices for using uncertainty regarding observations of traffic intersections to modify behavior of a vehicle are disclosed. In one embodiment, an example method includes determining a state of a traffic intersection using information from one or more sensors of a vehicle. The vehicle may be configured to operate in an autonomous mode. The method may also include determining an uncertainty associated with the determined state of the traffic intersection. The method may further include controlling the vehicle in the autonomous mode based on the determined state of the traffic intersection and the determined uncertainty.
Claims20
A method comprising:
- determining a state of a traffic intersection using information from one or more sensors of a vehicle, wherein determining the state of the traffic intersection comprises determining a state of a traffic signal of the traffic intersection, and wherein the vehicle is configured to operate in an autonomous mode;
- determining an uncertainty associated with the determined state of the traffic intersection;
- and
- controlling the vehicle in the autonomous mode based on the determined state of the traffic intersection and the determined uncertainty associated with the determined state of the traffic intersection.
A non-transitory computer-readable medium having stored therein instructions executable by a computing device to cause the computing device to perform functions comprising:
- determining a state of a traffic intersection using information from one or more sensors of a vehicle, wherein determining the state of the traffic intersection comprises determining a state of a traffic signal of the traffic intersection, and wherein the vehicle is configured to operate in an autonomous mode;
- determining an uncertainty associated with the determined state of the traffic intersection;
- and
- controlling the vehicle in the autonomous mode based on the determined state of the traffic intersection and the determined uncertainty associated with the determined state of the traffic intersection.
A vehicle configured to be operated in an autonomous mode, comprising:
- one or more sensors configured to obtain information associated with a traffic intersection;
- a memory;
- a processor;
- and
- instructions stored in the memory and executable by the processor to:
- determine a state of a traffic intersection based on the obtained information, wherein determining the state of the traffic intersection comprises determining a state of a traffic signal of the traffic intersection,
- determine an uncertainty associated with the determined state of the traffic intersection, and
- control the vehicle in the autonomous mode based on the determined stated of the traffic intersection and the determined uncertainty associated with the determined state of the traffic intersection.
