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.

Extract the movable path of other vehicles that interferes with the planned driving path of the own vehicle, that is, the interfering moving route, and select from the extracted interfering moving routes of other vehicles based on at least one of road shape, traffic rules, and traffic conditions. It is used to determine an interfering movement route of another vehicle required for the driving behavior of the own vehicle, and determines a driving behavior of the own vehicle corresponding to another vehicle moving along the selected interfering movement route.
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...
