Abstract
A risk degree estimation device of a driving assistance device calculates the potential risk degree at a plurality of intersection points in a mesh set around a host vehicle. The risk degree estimation device changes the amount of information relating to the potential risk degree calculated for the entire region of the mesh in which the intersection points are set in accordance with at least one of the environment and state of the host vehicle. For this reason, it becomes possible to calculate the potential risk degree around the host vehicle depending on the situation.

16. A risk degree calculation device comprising:
-
a risk degree calculation unit which calculates the risk degree at a plurality of points set around a host vehicle, wherein the risk degree calculation unit changes the amount of information relating to the risk degree calculated for the entire region in which the points are set in accordance with at least one of the environment and state of the host vehicle, and the risk degree calculation unit makes the amount of information relating to the risk degree calculated per unit area of the region in which the points are set when the speed of the host vehicle is high smaller than the amount of information relating to the risk degree calculated per unit area of the region in which the points are set when the speed of the host vehicle is low. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
