Driving control system for vehicle

A driving control system for a vehicle, comprising:

• a map information output means for outputting a map;
• a vehicle position detecting means for detecting a vehicle position of a subject vehicle on the map;
• a vehicle speed detecting means for detecting a vehicle speed;
• a turning radius determining means for determining a turning radius of the vehicle based on said detected vehicle speed;
• a maximum turning radius determining means for determining, on the basis of a portion of road which is in front of the vehicle position in a traveling direction on the map, a maximum vehicle-turning radius required for the vehicle to safely pass through said road portion;
• a passable vehicle speed calculating means for calculating a passable vehicle speed at which the vehicle is safely passable within dimensions of said road portion based on the determined maximum turning radius and the determined turning radius;
• and
• said map information output means, said vehicle position detecting means, said vehicle speed detecting means, said turning radius determining means, said maximum turning radius determining means, and said passable vehicle speed calculating means being operatively interconnected.

A driving control system for a vehicle, comprising:

• a vehicle position detecting means for detecting a vehicle position of a subject vehicle on the map;
• a vehicle speed detecting means for detecting a vehicle speed;
• a turning radius determining means for determining a turning radius of the vehicle based on said detected vehicle speed:
• a judging-section determining means for establishing a first section having a predetermined range and a second section having a range narrower than said predetermined range on a road in front of the vehicle position in a traveling direction;
• a judgment-execution determining means for judging whether or not the vehicle is safely passable through a road in the first section on the basis of the detected vehicle speed and a curved condition of the road on the map, and for determining, based on said judgment, whether or not a judgment of a passability or impassability of the vehicle through a road in the second section should be conducted;
• a passability/impassability judging means for judging whether or not the vehicle is safely passable within dimensions of the road in the second section based on the detected vehicle speed, the determined turning radius and the curved condition of the road on the map, when it is decided by the judgment-execution determining means that the judgment of the passability or impassability of the vehicle through the road in the second section should be conducted;
• means for providing at least one of an alarm and a vehicle speed adjustment based on said judgment of whether or not the vehicle is passable through the road in the second section;
• and
• said information output means, said vehicle position detecting means, said vehicle speed detecting means, said turning radius determining means, said judging-section determining means, said judgment-execution determining means, said passability/impassability judging means, and said providing means being operatively interconnected.
