Driving assistance method and device

Abstract

An interfering movement line which is an interfering route of possible movement by another vehicle interferes with a preset path of the vehicle is extracted; an interfering movement line of the othervehicle, said line being required to decide the driving action of the vehicle in question, is selected from among the extracted interfering movement lines of the other vehicle on the basis of the shape of a road, traffic regulations, and / or traffic conditions; and a driving action of the vehicle in question, said action corresponding to the other vehicle which is moving along the selected interfering movement line, is decided.

Description

technical field [0001] The present invention relates to a driving assistance method and device for assisting driving of a vehicle. Background technique [0002] As a driving assistance device, there is known a device that cannot be directly recognized by a sensor, but when a potential movable object such as a two-wheeled vehicle that exists in a blind spot of a movable object such as another motor vehicle is expected , predict the potential path, calculate the contact risk, and decide the driving action based on the calculated contact risk (Patent Document 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Unexamined Patent Publication No. 2011-96105 [0006] The problem to be solved by the invention [0007] However, in the case where the sensor cannot recognize and predict the potential route, the contact risk cannot be calculated, and the driving action cannot be determined. Therefore, when the search (search) range for d...

AI Technical Summary

Problems solved by technology

[0007] However, in situations where sensors cannot recognize and predict potential paths, exposure risks cannot be calculated and driving actions cannot be determined

Therefore, when the search (search) range when determining a driving action is a wide range, a range that cannot be recognized by the sensor is likely to occur within the search range, and there is a problem that it is easy to cause a situation where it is difficult to determine a driving action.
