REDUCE SPEED AHEAD INFORMATION DELIVERY
First Claim
1. A method, comprising:
- determining a position of a vehicle on a segment of a roadway over which the vehicle is currently travelling;
identifying a change in speed limit for a segment of the roadway that the vehicle is approaching relative to the current segment of the roadway;
assessing speed limit information of the current segment of the roadway and the approaching segment of the roadway;
determining a speed limit information presentation zone of the current segment of the roadway within which speed limit information for the approaching segment is to be presented to a driver of the vehicle after determining that a speed limit of the approaching segment of the roadway is lower than at least one of a speed limit of the current segment of the roadway and a current speed of the vehicle;
assessing a position of the vehicle relative to the speed limit information presentation zone; and
providing the speed limit information for the approaching segment of the roadway to the driver in response to determining that the vehicle is within the speed limit information presentation zone.

Abstract
A navigation system provides a position of the vehicle on a segment of a roadway and identities a change in speed limit relative to the current segment of the roadway. A traffic sign recognition system determines a speed limit information presentation zone of the current segment of the roadway after determining that a speed limit of the approaching segment of the roadway is lower than a speed limit of the current segment of the roadway and/or a current speed of the vehicle. Thereafter, the traffic sign recognition system assesses the position of the vehicle relative to the speed limit information presentation zone in response to determining that the vehicle i within the speed limit information presentation location, the traffic sign recognition system displays a visual representation of a speed limit sign designating the speed limit of the approaching segment of the roadway.

10. A vehicle, comprising:
-
a navigation system providing a position of the vehicle on a segment of a roadway over which the vehicle is currently travelling and identifying a change in speed limit for a segment of the roadway that the vehicle is approaching relative to the current segment of the roadway; and a traffic sign recognition system determining a speed limit information presentation zone of the current segment of the roadway within which speed limit information for the approaching segment is to be presented to a driver of the vehicle after determining that a speed limit of the approaching segment of the roadway is lower than at least one of a speed limit of the current segment of the roadway and a current speed of the vehicle;
assessing the position of the vehicle relative to the speed limit information presentation zone, and displaying a visual representation of a speed limit sign designating the speed limit of the approaching segment of the roadway in response to determining that the vehicle is within the speed limit information presentation zone. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A processor-readable medium having tangibly embodied thereon and accessible therefrom a set of instructions interpretable by at least one data processing device, the processor-readable medium being non-transitory, and the set of instructions configured for causing the at least one data processing device to carry out operations for:
-
determining a position of a vehicle on a segment of a roadway over which the vehicle is currently travelling; identifying a change in speed limit for a segment of the roadway that the vehicle is approaching relative to the current segment of the roadway; assessing speed limit information of the current segment of the roadway and the approaching segment of the roadway; determining a speed limit information presentation zone of the current segment of the roadway within which speed limit information for the approaching segment is to be presented to a driver of the vehicle after determining that a speed limit of the approaching segment of the roadway is lower than at least one of a speed limit of the current segment of the roadway and a current speed of the vehicle; assessing a position of the vehicle relative to the speed limit information presentation zone; and causing the speed limit information for the approaching segment of the roadway to be presented to the driver in response to determining that the vehicle is within the speed limit information presentation zone. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
