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.
