driving aids

Abstract

The present invention relates to a driving assistance device, comprising: a blind spot recognition unit that recognizes a blind spot for the driver in the traveling direction of the own 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. The speed range of the own vehicle in which the own vehicle is likely to come into contact with the moving body; the brake avoidance condition calculation unit that calculates the brake avoidance condition that the own vehicle can avoid contact with the moving body through the brakes and the moving body can avoid contact with the own vehicle through the brakes at least one of the contact brake avoidance conditions; a speed range correction unit that corrects the speed range based on the brake avoidance conditions calculated by the brake avoidance condition calculation unit; and a target speed calculation unit that calculates the speed range of the host vehicle based on the speed range target speed.

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 device that considers an object suddenly appearing from a blind spot when entering an intersection or the like, and performs driving assistance. For example, the driving assistance device in Patent Document 1 predicts the road ahead 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 whether the object can move. If the range overlaps with the predicted course of the host vehicle, it is determined that there is a possibility of collision, and driving assistance is performed 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 using the predicted cours...

Problems solved by technology

Therefore, conventional driving assistance devices avoid collisions by judging whether there is a collision when traveling on the current predicted road, and cannot calculate how much to reduce the speed to avoid collisions, how much to dodge to avoid collisions, etc.

In addition, the collision judgment of conventional driving assistance devices largely 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 steering), the accuracy of collision judgment may decrease.

In this case, the conventional driving assistance device may cause discomfort to the driver by performing unnecessary driving assistance or not performing driving assistance at the necessary timing.
