no. 1 approach

[0023] Such as figure 1 As shown, the driving assistance device according to the first embodiment of the present invention includes: an information supply unit 1, a processing unit 2 that supplies various information through the information supply unit 1 and processes calculations necessary for the operation of the driving assistance device, a vehicle control unit 3, Output section 5. Such as figure 2 As shown, the driving assistance device according to the first embodiment is mounted on a vehicle, and assists driving when the own vehicle C turns left or right (turns left or right). The own vehicle C may be a self-driving vehicle that automatically drives on a set travel route, or may be a vehicle that travels according to the driver's operation.

[0024] The information supply unit 1 includes a road information acquisition unit 11 , an own vehicle position acquisition unit 12 , an object detection unit 13 , and a left / right turn information detection unit 14 . The road in...

no. 2 approach

[0066] Such as Figure 8 As shown, the driving assistance device according to the second embodiment of the present invention differs from the first embodiment in that the processing unit 2A further includes a virtual trajectory estimation unit 27 , a first standby position setting unit 28 , and a second standby position setting unit 29 . different. Other configurations not described in the second embodiment are substantially the same as those in the first embodiment, and description thereof will be omitted because they are redundant.

[0067] The virtual trajectory estimation unit 27 estimates a virtual trajectory when a vehicle from the oncoming lane turns left and right based on the size of the intersection, etc., when the left and right turn information is detected by the left and right turn information detection unit 14 . The blind spot estimation unit 22 estimates a virtual blind spot of the object detection unit 13 on the oncoming lane based on the virtual trajectory es...

Abstract

A driving assistance device in which an object detection unit detects an object in front of a vehicle, and based on the current position of the vehicle in road information and the driving path of the vehicle, detects that the vehicle crosses the opposite direction at an intersection after a predetermined time. The left and right turn information of the lane turning left and right, when the left and right turn information is detected, based on the detection result of the object detection unit and the road information, it is judged whether there is a standby vehicle waiting to turn left or right at the intersection from the opposite lane, and The object detection unit formed by the waiting vehicle is estimated to be in a blind spot in the oncoming lane, and based on the estimated blind spot, a waiting area where the own vehicle waits to turn left and right is set.

Description

technical field [0001] The present invention relates to a driving assistance device and a driving assistance method for assisting driving of a vehicle. Background technique [0002] When a vehicle equipped with a sensor that detects an object ahead crosses the oncoming lane at an intersection and makes a left or right turn (left or right turn), there may be cases when waiting for the left or right turn (waiting for a left and right turn) due to waiting left and right from the oncoming lane. A turning vehicle creates a sensor blind spot in the oncoming lane. On the other hand, a driving assistance device is proposed that notifies the driver of the risk of turning left or right according to the degree of the blind spot of the sensor formed by the vehicle from the oncoming lane (see Patent Document 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: (Japanese) Unexamined Patent Application Publication No. 2011-90582 [0006] However, the ...
