Vehicle safety running apparatus
First Claim
1. A vehicle safety running apparatus comprising:
- storage means (M1) for storing road data including intersections;
subject vehicle position detecting means (M2) for detecting the position of a subject vehicle;
route setting means (M3) for setting a route to a destination;
vehicle condition detecting means (M4) for detecting a vehicle condition of said subject vehicle including at least a vehicle speed thereof;
bend portion detecting means (M5) for detecting curves and intersections existing along a traveling direction of said subject vehicle based on a road data stored in said storage means and the subject vehicle position detected by said subject vehicle position detecting means (M2); and
proper condition determining means (M6) for calculating, based on information on curves and intersections detected by said bend portion detecting means (M5), proper vehicle conditions for passing through said curves and intersections, and determining whether or not said subject vehicle can properly pass through said curves and intersections based on the result of a comparison of the proper vehicle condition calculated with the vehicle condition detected by said vehicle condition detecting means (M4); and
running difficulty determining means (M7) for determining a degree of difficulty in running on a road on which said subject vehicle is traveling, wherein when said bend portion detecting means (M5) detects an intersection branching into a plurality of branch roads in a state in which a route guidance based on a set route is not carried out, said proper condition determining means (M6) selects a branch road determined by said running difficulty determining means (M7) as having a lowest degree of difficulty in running and determining whether or not said subject vehicle can pass through said branch road.

Abstract
In a vehicle safety running apparatus, when a route guidance by a navigation system is not in operation, a determination on passableness is carried out as a target on a branch road of a plurality of branch roads branched from an intersection ahead of the subject vehicle which has lowest with respect to the degree of difficulty in running or a branch road having a smallest intersection angle formed by a road on which the subject vehicle is advancing and the branch road and a curve on the branch road, whereby an automatic deceleration control can be performed or an alarm can be given to the driver even when the route guidance is not in operation, and moreover the automatic deceleration control and/or alarming the driver is prevented from being performed unnecessarily, thereby making it possible to suppress to a minimum level the physical disorder that the driver may feel.
