Selectable lane-departure warning system and method
First Claim
1. A selectable lane-departure warning system adapted for use with a vehicle traveling upon a thoroughfare having at least one lane-marking, and by an operator, said system comprising:
- a driving-mode selection device selectable between a plurality of driving modes by the operator, and presenting a current selected driving mode;
at least one sensor operable to detect the relative location and configuration of the lane-marking; and
a controller communicatively coupled to the device and sensor, and configured to modify a predetermined warning threshold to one of a plurality of adjusted thresholds, wherein each adjusted threshold is correlated to a separate one of the plurality of driving modes, said sensor and controller being cooperatively configured to determine a spatial relationship between the vehicle and lane-marking, and produce a lane departure warning, when the spatial relationship exceeds the adjusted threshold correlative to the current selected driving mode.

Abstract
A selectable lane departure detection system (10) adapted for use by an operator, and with a vehicle (12) traveling upon a thoroughfare having lane-markings (16), and including at least one vehicle condition sensor (22 through 28), a tracking sensor (20) or differential global positioning system (38) configured to determine the location and configuration of the lane-markings (16), and a controller (32) communicatively coupled to the sensors (20 through 28), and configured to determine a spatial relationship between the vehicle (12) and lane-markings (16), determine a sporty driving maneuver by or preference of the operator, modify a predefined warning threshold when so determined, compare the relationship to the adjusted threshold, and issue a warning when the relationship does not exceed the threshold.

15. A self-adjusting lane-departure warning system adapted for use with a vehicle traveling upon a thoroughfare having at least one lane-marking, said system comprising:
-
at least one vehicle condition sensor configured to determine a current vehicle condition, at least one tracking sensor operable to detect the relative location and configuration of the lane-marking; and
a controller communicatively coupled to the vehicle condition and tracking sensors, and configured to compare the condition to a condition threshold, and autonomously modify a predetermined warning threshold to an adjusted threshold, wherein the adjusted threshold is correlated to the condition, when the condition exceeds the condition threshold, said tracking sensor and controller being cooperatively configured to determine a spatial relationship between the vehicle and lane-marking, and produce a lane departure warning, when the spatial relationship exceeds the adjusted threshold. - View Dependent Claims (16, 17)

18. A selectable lane departure detection system adapted for use by an operator, and with a vehicle traveling upon a thoroughfare, said system comprising:
-
at least one vehicle condition sensor configured to determine a current vehicle condition;
a differential global positioning system (DGPS) configured to determine the current position coordinates of the vehicle;
a map database including a plurality of maps, wherein each map includes a plurality of thoroughfare position points, and indicia correlated with each of the points, and the indicia includes indication of a lane-marking location; and
a controller communicatively coupled to the vehicle condition sensor, DGPS, and database, and configured to match the current position coordinates with a thoroughfare position point, compare the condition to a condition threshold, and autonomously modify a predetermined warning threshold to an adjusted threshold, when the condition exceeds the condition threshold, said controller, DGPS, and database being cooperatively configured to determine a spatial relationship between the vehicle position point and the nearest lane-marking position point, and produce a lane departure warning, when the spatial relationship exceeds the adjusted threshold. - View Dependent Claims (19, 20)
