Abstract
A system for determining the passability of a vehicle through a section of road ahead of the vehicle is controlled based on coordinates of a plurality of nodes N,(N,, N,, N,, N,. . . ) constituting the road section ahead of a subject vehicle. The system calculates a passing-state determination amount &thgr;,/L,for each of the nodes N,, and based on the passing-state determination amount &thgr;,/L,, the system then determines whether the vehicle can positively or safely pass through the road section. The passing-state determination amount &thgr;,/L,serves as an indicator which represents a degree of difficulty in the passage of the vehicle through the nodes N,and which is obtained, for example, by dividing an angle &thgr;,formed by a line segment connecting the adjacent nodes N,by a distance L,between the adjacent nodes N,. Even if only one or two nodes N,exist on a curve, it is possible to accurately determine whether the vehicle can pass the curve by using the passing-state determination amount &thgr;,/L,.
