[0004] However, even when it is judged that the other vehicle is not traveling in the adjacent lane because the sensor of the other vehicle cannot detect the position of the other vehicle with high accuracy, in fact, sometimes the other vehicle is traveling in the adjacent lane.

no. 1 approach 》

[0033] figure 1 It is a figure which shows the structure of the travel control apparatus 100 of this embodiment. Such as figure 1 As shown, the travel control device 100 of this embodiment includes: a surrounding detection sensor 110 , a vehicle position detection device 120 , a map database 130 , a presentation device 140 , a drive control device 150 , and a control device 160 . These devices are connected by in-vehicle LAN in addition to CAN (Controller Area Network) in order to exchange information with each other.

[0034] The surrounding detection sensor 110 detects obstacles (other vehicles, etc.) and road markings (lane markings, curbs, etc.) existing around the own vehicle. As the surrounding detection sensor 110 , for example, a front camera that captures the front of the own vehicle, a rear camera that captures the rear of the host vehicle, a side camera that captures the side of the host vehicle, etc. can be used. In addition, as the surrounding detection sensor ...

[0075] Next, a travel control device according to a second embodiment will be described. The travel control device 100 of the second embodiment has the same configuration as the travel control device 100 of the first embodiment, and is the same as the first embodiment except that it operates as described below.

[0076] The surrounding vehicle allocation function of the control device 160 in the second embodiment predicts the lanes of the surrounding vehicles based on the direction of travel of each lane in the road on which the surrounding vehicles are traveling and the lighting status of the blinkers of the surrounding vehicles, and arranges the surrounding vehicles. within the predicted lane.

[0077] here, Figure 8 is a diagram illustrating a scene where the own vehicle enters a T-junction. exist Figure 8In the illustrated example, the surrounding vehicle A is actually traveling on the lane A, but the surrounding vehicle A is detected between the lanes A and B due to ...

[0097] Next, a travel control device according to a third embodiment will be described. The travel control device 100 of the third embodiment has the same configuration as the travel control device 100 of the first embodiment, and is the same as the first embodiment except that it operates as described below.

[0098] In the third embodiment, the surrounding vehicle arrangement function of the control device 160 determines the positions of the host vehicle and surrounding vehicles on the map based on road indications and road shapes (including road curves). In addition, road indications are stop lines, signs, signal machines, fire hydrants, etc., which can be fixed on the road surface or its vicinity, and can be used as indications. In addition, the road shape is a road shape such as a curve.

[0099]The surrounding vehicle allocation function detects road indications and road shapes based on detection results of a camera or a laser rangefinder constituting the surrounding de...

Abstract

A driving control method, using a detector (110) that detects a moving body around a self-vehicle to determine the position of the mobile body, wherein the direction of travel of a lane in a road on which the mobile body is traveling is detected based on map information, and when the self-vehicle changes In the case of the traveling direction, the position of the moving object is predicted based on the traveling direction of the lane.

Description

technical field [0001] The present invention relates to a travel control method and a travel control device for controlling travel of a vehicle. Background technique [0002] Currently, there is known a technique for judging whether or not another vehicle is in a lane (relative lane) adjacent to the lane in which the own vehicle is traveling (own lane) based on the number of lanes contained in map information and the positions of other vehicles received from other vehicles. Adjacent lane) (for example, patent document 1). [0003] Patent Document 1: (Japanese) Unexamined Patent Publication No. 2013-134567 [0004] However, even when it is determined that the other vehicle is not traveling in the adjacent lane because the sensor of the other vehicle cannot detect the position of the other vehicle with high accuracy, in fact, sometimes the other vehicle is traveling in the adjacent lane. . Contents of the invention [0005] The problem to be solved by the present inventio...
