Vehicle control system and method in which restrictions on travel of the vehicle are determined based on an indication of the visibility of a driver and information about objects moving in a direction opposite to the direction of travel of the vehicle are considered. The travel restrictions include preventing a passing maneuver on a two-lane road when an oncoming vehicle precludes safely initiating or completing an already-initiated passing maneuver. A warning system is provided to warn a driver about the travel restrictions so that the driver will, hopefully, not attempt an unsafe maneuver.

1. A driving monitoring system for a vehicle, comprising: a visibility determining system that provides an indication of the visibility of a driver of the vehicle;an image obtaining system oriented to obtain images of an area in front of the vehicle and derive information about an object in the obtained images including distance between the vehicle and the object; anda warning system that, based at least in part on the indication of the visibility of the driver provided by said visibility determining system, the distance between the vehicle and the object derived by said image obtaining system, and movement of the vehicle, warns a driver when a driving maneuver should be aborted. 2. The system of claim 1, wherein the object is at least partially obstructed from the view of the driver. 3. The system of claim 1, wherein said visibility determining system is configured to consider topography of a road the vehicle is travelling on when providing the indication of the visibility of the driver. 4. The system of claim 3, wherein said visibility determining system is configured to access a database of topographical information to obtain information about the topography of the road the vehicle is travelling on. 5. The system of claim 4, wherein said topographical information database is arranged partly on the vehicle. 6. The system of claim 4, wherein said topographical information database is arranged partly at a site off of the vehicle and provided to the vehicle via a communications link. 7. The system of claim 1, wherein said visibility determining system is configured to consider atmospheric conditions around the vehicle when providing the indication of the visibility of the driver. 8. The system of claim 7, further comprising on-board vehicle sensors configured to obtain atmospheric condition information. 9. The system of claim 7, wherein said visibility determining system is configured to access a database of atmospheric condition information to obtain information about the atmospheric conditions around the vehicle. 10. The system of claim 1, wherein said visibility determining system comprises a vehicle illumination system and is configured to determine the visibility in consideration of backscatter from said vehicle illumination system. 11. The system of claim 1, wherein said image obtaining system comprises a lidar or camera system. 12. The system of claim 1, further comprising a processor coupled to said visibility determining system, said image obtaining system and said warning system and that controls said warning system based on the indication of the visibility of the driver provided by said visibility determining system and the distance between the vehicle and the object derived by said image obtaining system. 13. A method for monitoring driving of a vehicle, comprising: obtaining an indication of visibility of a driver of the vehicle;obtaining images of an area in front of the vehicle using an image acquiring system;deriving, using a processor, information about an object in the obtained images including distance between the vehicle and the object; andwarning a driver via a warning system based at least in part on the obtained indication of the visibility of the driver, the distance between the vehicle and the object, and movement of the vehicle, when a driving maneuver should be aborted. 14. The method of claim 13, wherein the object is at least partially obstructed from the view of the driver. 15. The method of claim 13, wherein the step of obtaining an indication of the visibility of the driver comprises obtaining topographical information about a road the vehicle is travelling on. 16. The method of claim 15, wherein the topographical information is obtained from an off-vehicle database. 17. The method of claim 13, wherein the step of obtaining an indication of the visibility of the driver comprises obtaining information about atmospheric conditions around the vehicle. 18. The method of claim 17, wherein the information about atmospheric conditions is obtained by on-board vehicle sensors. 19. The method of claim 17, wherein the information about atmospheric conditions is obtained by access to an off-vehicle database of atmospheric condition information. 20. The method of claim 13, wherein the step of obtaining an indication of the visibility of the driver comprises: obtaining topographical information about a road the vehicle is travelling on;obtaining information about atmospheric conditions around the vehicle; andassessing visibility in view of the obtained topographical information and information about atmospheric conditions in order to provide the indication of the visibility of the driver.
