Autonomous vehicle system configured to respond to temporary speed limit signs
First Claim
1. A computer-implemented method comprising:
- identifying, by one or more computing devices, a speed limit sign in a vehicle'"'"'s environment;
identifying, by the one or more computing devices, a location and orientation corresponding to the speed limit sign;
determining, by the one or more computing devices, whether the location and orientation of the identified speed limit sign corresponds to a pre-stored location and a pre-stored orientation of a speed limit sign that is pre-stored in map information;
when the location and orientation do not correspond to the pre-stored location and the pre-stored orientation, determining, by the one or more computing devices, an effect zone of the identified speed limit sign based on the location and orientation of the identified speed limit sign and characteristics of surrounding areas or other detected object before or after the identified speed limit sign;
determining, by the one or more computing devices, a response of the vehicle based on the determined effect zone of the identified speed limit sign; and
controlling, by the one or more computing devices, the vehicle based on the determined response.

Abstract
Aspects of the disclosure provide for a method for identifying speed limit signs and controlling an autonomous vehicle in response to detected speed limit signs. The autonomous vehicle'"'"'s computing devices identifies a speed limit sign in a vehicle'"'"'s environment and a location and orientation corresponding to the speed limit sign. Then, the and orientation location of the speed limit sign is determined to not correspond to a pre-stored location and a pre-stored orientation of a speed limit sign that is pre-stored in map information. An effect zone of the speed limit sign is determined based on the location and orientation of the speed limit sign and characteristics of surrounding areas or other detected object before or after the speed limit sign. The autonomous vehicle'"'"'s computing devices determines a response of the vehicle based on the determined effect zone, and controls the autonomous vehicle based on the determined response.

9. A system comprising:
-
a perception system configured to detect an object in a vehicle'"'"'s environment at a detected location; a memory storing map information; and one or more computing devices configured to; identify a speed limit sign in a vehicle'"'"'s environment; identify a location and orientation corresponding to the identified speed limit sign; determine whether the location and orientation of the identified speed limit sign corresponds to a pre-stored location and a pre-stored orientation of a speed limit sign that is pre-stored in the map information; when the location and orientation do not correspond to the pre-stored location and the pre-stored orientation of the pre-stored speed limit sign, determine an effect zone of the identified speed limit sign based on the location and orientation of the identified speed limit sign and characteristics of surrounding areas or other detected object before or after the identified speed limit sign; determine a response of the vehicle based on the determined effect zone of the identified speed limit sign; and control the vehicle based on the determined response. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A non-transitory, tangible computer-readable storage medium on which computer readable instructions of a program are stored, the instructions, when executed by one or more computing devices, cause the one or more computing devices to perform a method, the method comprising:
-
identifying a speed limit sign in a vehicle'"'"'s environment; identifying a location and orientation corresponding to the identified speed limit sign; determining whether the location and orientation of the identified speed limit sign corresponds to a pre-stored location and pre-stored orientation of a speed limit sign that is pre-stored in map information; when the location and orientation do not correspond to the pre-stored location and pre-stored orientation of the pre-stored speed limit sign, determining an effect zone of the identified speed limit sign based on the location and orientation of the identified speed limit sign and characteristics of surrounding areas or other detected object before or after the identified speed limit sign; determining a response of the vehicle based on the determined effect zone of the identified speed limit sign; and controlling the vehicle based on the determined response. - View Dependent Claims (19, 20)
