System and method for providing a speed warning and speed control
First Claim
1. A controller adapted to:
- receive signals indicative of an image of a sign including a representation of at least one posted speed limit for a current section of a road on which an associated vehicle is traveling;
evaluate the image to identify any of the at least one posted speed limits;
select any of the at least one posted speed limits greater than or equal to a predetermined threshold speed limit as a possible speed limit for the associated vehicle;
determine an identified speed limit for the associated vehicle based on all of the possible speed limits;
transmit a signal for controlling a speed of the associated vehicle based on the identified speed limit; and
transmit a signal for displaying the identified speed limit on a display.

Abstract
A controller is adapted to receive signals indicative of an image including a representation of a posted speed limit for a current section of a road on which an associated vehicle is traveling. The controller evaluates the image to identify the posted speed limit and dynamically determines if the posted speed limit is above a predetermined threshold speed limit. Only if the posted speed limit is above the predetermined threshold speed limit, the controller sets the identified posted speed limit as a warning threshold. If a speed of the associated vehicle is more than a predetermined range over the warning threshold, the controller transmits a warning signal to a notifier for notifying an operator of the associated vehicle and controls a speed of the vehicle based on the posted speed limit.

12. A controller adapted to:
-
receive signals indicative of an image of a sign including a representation of a possible speed limit for a current section of a road on which an associated vehicle is traveling; evaluate the image to identify if the sign indicates a school zone speed limit; only if the evaluation of the image indicates the sign is not a school zone speed limit, set a warning threshold speed limit to the possible speed limit; and if a speed of the associated vehicle is more than a predetermined range over the warning threshold speed limit, transmit a warning signal to a notifier for notifying an operator of the associated vehicle by causing the warning threshold speed limit and a warning message to be displayed on the notifier. - View Dependent Claims (13, 14, 15, 16)

17. A method for setting a warning threshold speed limit, the method comprising:
-
receiving signals indicative of an image of a sign including a representation of a possible speed limit for a current section of a road on which an associated vehicle is traveling; evaluating the image to identify if the sign indicates a school zone speed limit; only if the evaluation of the image indicates the sign is not a school zone speed limit, setting a warning threshold speed limit to the possible speed limit; if a speed of the associated vehicle is more than a predetermined range over the warning threshold speed limit, transmitting a warning signal to a notifier for notifying an operator of the associated vehicle by causing the posted speed limit and a warning message to be displayed on the notifier; and only if the posted speed limit is above the predetermined threshold speed limit, controlling a speed of the associated vehicle based on the set posted speed limit. - View Dependent Claims (18, 19, 20)
