    摘要： The object of the invention is to provide a driving assistance device that is able to perform driving assistance considering potential risks. A device for providing driving assistance for a driver of the vehicle to avoid the object of the risk subject when driving the vehicle, which includes : an object determination unit that detects the object; a collision prediction time calculation unit that calculates a time to collision which is a time indicating a degree to which the vehicle approaches to the object; an estimated risk level determination unit that determines an estimated risk level indicating a possibility of the object moving onto a predicted travelling path of the vehicle; and a driving assistance content determination unit that determines driving assistance content based on the collision prediction time and the estimated risk level. Thereby, even in a case where the risk is not being manifested, that is, a case where the object is not present on the predicted travelling path of the vehicle C, the potential risk related to the object is considered in determining the driving assistance content. Accordingly, it is possible to provide the driving assistance considering the potential risk.
