1. A host vehicle comprising:
- a driving assistance device including a risk degree calculation unit, the driving assistance device further comprising at least one of the following;
an obstacle detection device;
a white line detection device;
a road shape detection device;
a driver state detection device;
a host vehicle traveling situation detection device;
a host vehicle position detection device;
a surroundings database;
a driver operation state detection device;
a control mode selector;
a target route generation device,a driving assistance ECU,a display device; and
a speech device,wherein the risk degree calculation unit calculates the risk degree at a plurality of points in a mesh set according to a surface area of a region around the 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 a number of the points is set in accordance with at least one of the environment and state of the host vehicle, andthe risk degree calculation unit varies the number of the points within the mesh set according to the surface area of the region around the host vehicle to decrease when the speed of the host vehicle increases.

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.
