driving aids

Abstract

The present invention provides a driving assistance device comprising: a blind spot recognition unit that recognizes a blind spot for the driver in the traveling direction of the host vehicle; The moving body information of the estimated speed of the moving body is used as information related to the moving body; the speed area calculation unit calculates the moving body information based on the moving body information set by the moving body information setting unit. a speed region of the own vehicle in which the own vehicle is likely to come into contact with the moving object; and a target speed calculating unit which calculates the target speed of the own vehicle based on the speed region.

Description

technical field [0001] The invention relates to a driving assistance device. Background technique [0002] As a conventional driving assistance device, there is known a driving assistance device that performs driving assistance in consideration of an object that suddenly appears from a blind spot when entering an intersection or the like. For example, the driving assistance device in Patent Document 1 predicts the traveling route of the host vehicle, recognizes a blind spot for the driver in the traveling direction of the host vehicle, predicts an object that may suddenly appear from the blind spot, and detects that the object may move. Range, to determine the possibility of collision when the range overlaps with the predicted travel route of the vehicle, and then perform driving assistance to avoid the collision. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2006-260217 [0004] However, conventional driving assistance devices perform driving assistance by usi...

Problems solved by technology

Therefore, conventional driving assistance devices avoid collisions by judging whether there is a collision or not when driving along the current predicted travel route, and cannot perform calculations such as how much speed should be reduced to avoid collisions or how much to avoid collisions.

In addition, the collision judgment of the conventional driving assistance device greatly depends on the prediction accuracy of the future position of the own vehicle.

Therefore, when the prediction accuracy decreases (for example, when the host vehicle is accelerating, decelerating, or turning), the accuracy of collision judgment may decrease

In this case, the conventional driving assistance device may give the driver a sense of discomfort by performing unnecessary driving assistance or failing to provide driving assistance at the necessary timing.
