  "textContent": "An in-vehicle electronic controller includes a risk map generating unit that determines a traveling risk level in an area around the vehicle, based on external environment information acquired by an external environment sensor installed in the vehicle, movement information on the vehicle, and map information, and that maps the traveling risk level onto a map to generate a risk map; and a track generating unit that generates a traveling track of the vehicle, using the risk map. The track generating unit generates at least one binarized image representing the risk map divided into a low risk area and a high risk area, by a binarization process by which whether the traveling risk level is larger than a given set value is determined, performs a thinning process on the at least one binarized image to determine a center line in a width direction of the low risk area, and generates a traveling track of the vehicle, based on the determined center line.",
