Scenario based audible warnings for autonomous vehicles
First Claim
1. A method of providing audible indications to objects located externally to a vehicle having an autonomous driving mode, the method comprising:
- controlling, by one or more processors, the vehicle in the autonomous driving mode along a particular path;
receiving, by the one or more processors, information identifying a characteristic of an object and a location of the object external to the vehicle;
determining, by the one or more processors, that the vehicle is prevented from proceeding along the particular path because of the location of the object;
when the vehicle is determined to be prevented from proceeding, identifying, by the one or more processors, a scenario from a set of predetermined scenarios using the characteristic, each scenario of the set of predetermined scenarios being associated with a predetermined period of time and a type of audible indication;
waiting, by the one or more processors, the predetermined period of time associated with the identified scenario;
after the waiting the predetermined period of time associated with the identified scenario, determining, by the one or more processors, that the object continues to prevent the vehicle from proceeding along the particular path;
identifying, by the one or more processors, an audible indication according to the type of audible indication associated with the identified scenario; and
when the object is determined to continue to prevent the vehicle from proceeding along the particular path, playing, by the one or more processors, the audible indication through a speaker of the vehicle to encourage the object to take an action to allow the vehicle to proceed along the particular path.

Abstract
Aspects of the disclosure relate to providing audible indications to objects located externally to a vehicle having an autonomous driving mode. For instance, a vehicle is controlled in the autonomous driving mode along a particular path. Information identifying a characteristic and a location of an object is received. When vehicle is determined to be prevented from proceeding along the particular path because of the location of the object, a scenario is identified using the characteristic. The scenario is associated with a predetermined period of time and a type of audible indication used to identify an audible indication. After the waiting the predetermined period, when the object is determined to still be preventing the vehicle from proceeding along the particular path, the audible indication is played through a speaker of the vehicle to encourage the object to take an action to allow the vehicle to proceed along the particular path.

12. A system for providing audible indications to objects located externally to a vehicle having an autonomous driving mode, the system comprising:
one or more processors configured to; control the vehicle in the autonomous driving mode along a particular path; receive information identifying a characteristic of an object and a location of the object external to the vehicle; determine that the vehicle is prevented from proceeding along the particular path because of the location of the object; when the vehicle is determined to be prevented from proceeding, identify a scenario from a set of predetermined scenarios using the characteristic, each scenario of the set of predetermined scenarios being associated with a predetermined period of time and a type of audible indication; wait the predetermined period of time associated with the identified scenario; after the waiting the predetermined period of time associated with the identified scenario, determine that the object continues to prevent the vehicle from proceeding along the particular path; identify an audible indication according to the type of audible indication associated with the identified scenario; and when the object is determined to continue to prevent the vehicle from proceeding along the particular path, play the audible indication through a speaker of the vehicle to encourage the object to take an action to allow the vehicle to proceed along the particular path. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A non-transitory computer readable storage medium on which instructions are stored, the instructions, when executed by one or more processors cause the one or more processors to perform a method of providing audible indications to objects located externally to a vehicle having an autonomous driving mode, the method comprising:
-
controlling the vehicle in the autonomous driving mode along a particular path; receiving information identifying a characteristic of an object and a location of the object external to the vehicle; determining that the vehicle is prevented from proceeding along the particular path because of the location of the object; when the vehicle is determined to be prevented from proceeding, identifying a scenario from a set of predetermined scenarios using the characteristic, each scenario of the set of predetermined scenarios being associated with a predetermined period of time and a type of audible indication; waiting the predetermined period of time associated with the identified scenario; after the waiting the predetermined period of time associated with the identified scenario, determining that the object continues to prevent the vehicle from proceeding along the particular path; identifying an audible indication according to the type of audible indication associated with the identified scenario; and when the object is determined to continue to prevent the vehicle from proceeding along the particular path, playing the audible indication through a speaker of the vehicle to encourage the object to take an action to allow the vehicle to proceed along the particular path.
