Slow or stopped vehicle ahead advisor with digital map integration
First Claim
1. A selectively communicating slow vehicle advisory system adapted for use with a trailing vehicle having an operator, and a host vehicle traveling upon a thoroughfare, and communicatively coupled to and spaced from the trailing vehicle, said system comprising:
- at least one vehicle condition-sensor configured to determine the current speed of the host vehicle;
a normal speed determination sub-system configured to determine a normal speed of the host vehicle;
a controller communicatively coupled to the sensor and sub-system and configured to compare the current and normal speeds, so as to determine a speed discrepancy, compare the discrepancy to a speed threshold, and cause to be transmitted to the trailing vehicle a signal, only when the discrepancy exceeds the threshold; and
a slow-vehicle alert generator configured to generate an alert at the trailing vehicle, upon receipt of the signal.

Abstract
A driver assistance or collision avoidance system is adapted for use with trailing and preceding host vehicles, and in a preferred embodiment includes a preceding vehicle speed sensor for determining the current speed of the preceding vehicle at a point; a vehicle-to-vehicle communication sub-system; a normal speed determining sub-system operable to determine the normally expected speed of the preceding vehicle at the point, and including an exterior remote vehicle sensor or digital map-indicia database; and a controller configured to compare the current and normally expected speeds, and the discrepancy there-between to a threshold, and cause an alert to be generated only when the discrepancy exceeds the threshold or an otherwise stalled condition is determined.

16. A selectively communicating slow vehicle advisory system adapted for use with a trailing vehicle having an operator, and a host vehicle traveling upon a thoroughfare, and communicatively coupled to and spaced from the trailing vehicle, said system comprising:
-
at least one vehicle condition-sensor configured to determine the current speed of the host vehicle; a normal speed determination sub-system configured to determine a normal speed of the host vehicle, said sub-system including a locator device, and a map database, said locator being configured to determine the current position coordinates of the host vehicle, said map including a plurality of position points representing the thoroughfare, and indicia correlated to said points, wherein the indicia includes the normal speed at the location, said locator, and database being further configured to match the current position coordinates with a position coordinate and retrieve the normal speed at the location; a controller communicatively coupled to the sensor and sub-system, and configured to compare the current and normal speeds, so as to determine a speed discrepancy, compare the discrepancy to a speed threshold not less than positive 10 miles per hour, as measured by subtracting the preceding vehicle current speed from its normal speed at the location, and cause to be transmitted to the trailing vehicle a signal, only when the discrepancy exceeds the threshold; and a remote vehicle alert generator configured to generate a plurality of differing alerts at the trailing vehicle, wherein each alert correlates to a relative direction from the trailing vehicle to the host vehicle.

17. A selectively alerting slow vehicle advisory system adapted for use with a preceding vehicle, and a host vehicle having an operator, traveling upon a thoroughfare, and communicatively coupled to and spaced from the preceding vehicle, said system comprising:
-
a preceding vehicle speed sensor configured to determine the current speed of preceding vehicle; a preceding vehicle locator configured to determine the current position coordinates of the preceding vehicle; a location and speed communication sub-system configured to at least periodically communicate the preceding vehicle speed and location to the host vehicle; a normal speed determination sub-system configured to determine a normal speed of the preceding vehicle at the location; and a controller configured to compare the current and normal speeds, so as to determine a speed discrepancy, compare the discrepancy to a speed threshold, and cause to be generated an alert, only when the discrepancy exceeds the threshold. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
