Abstract:
1. A lane keeping system for use in a vehicle driving in a lane on a road, said lane keeping system comprising: a controller; a lane delimiter detection device; said lane delimiter detection device comprising a camera disposed behind a windshield of the vehicle and having a field of view through the windshield and forward of the vehicle; wherein the controller is responsive to an output of the lane delimiter detection device that is indicative of a sensed position of a left lane delimiter on the road on a left side of the vehicle and a sensed position of a right lane delimiter on the road on a right side of the vehicle, wherein, responsive to the output of the lane delimiter detection device, the controller is operable to: a) establish a safe zone having a left safe zone delimiter based on the sensed position of the left lane delimiter and a right safe zone delimiter based on the sensed position of the right lane delimiter, wherein the safe zone has a width between the left and right safe zone delimiters, b) take a corrective action responsive to the controller determining that the vehicle is at risk of unintentionally leaving the safe zone, wherein the corrective action is at least one action selected from the group of actions consisting of (i) notifying the driver that the vehicle is at risk of leaving the safe zone and (ii) applying a steering correction to the vehicle, and c) adjust the positions of the left safe zone delimiter and the right safe zone delimiter so as to adjust the width of the safe zone, wherein the controller adjusts the positions responsive to the vehicle remaining within the safe zone for a selected period of time and without any corrective action being taken during that selected period of time.
