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 (retrieval) range when determining the driving behavior 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 the driving behavior.

The invention includes extracting an interference traffic line that is a route along which another vehicle can move and that interferes with a planned travel route of a subject vehicle, determining anecessary length of the extracted interference traffic line of the other vehicle, which length is necessary for determining a driving action of the subject vehicle, on the basis of at least one of a shape of a road, a traffic rule, and a traffic situation, and determining the driving action of the subject vehicle to respond to the other vehicle moving along the interference traffic line using a range of the determined necessary length of the interference traffic line as a determination object.
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 (retrieval) range fo...
