[0005] However, in the prior art, it is only determined based on the relationship between objects in front of and behind the target lane of the lane change of the own vehicle and the relationship between the own vehicle, so there are areas where lane changes are not recommended even in terms of traffic regulations. It will be judged that it is possible to change the lane

[0020] figure 1 It is a configuration diagram showing the configuration of the traveling control device 100 according to the present embodiment. Such as figure 1 As shown, the travel control device 100 of this embodiment has a sensor group 110 , a map database 120 , a presentation device 130 , a drive mechanism 140 , and a control device 150 . These devices are connected to other vehicle-mounted LANs through CAN (Controller Area Network) to receive and send mutual information.

[0021] The sensor group 110 includes a GPS device that detects the position of the own vehicle, and a vehicle speed sensor that detects the speed of the own vehicle. The GPS device periodically acquires the position information of the host vehicle by detecting radio waves transmitted from a plurality of satellite communications, and based on the acquired position information of the host vehicle, angle change information acquired from the gyro sensor, and vehicle speed acquired from the vehicle speed ...

[0067] 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 for operations described below.

[0068] In the second embodiment, the lane change determination function of the control device 150 estimates the vehicle speed of the host vehicle when the host vehicle is traveling on the road ahead based on the shape of the road ahead of the host vehicle, and sets the judgment target region R1 based on the estimated vehicle speed of the host vehicle. .

[0069] here, Figure 8 It is a figure for demonstrating the setting method of the determination object area|region R1 of 2nd Embodiment. Figure 8 In the example shown, a scene in which the own vehicle enters a curve after the own vehicle travels on a straight road at a speed of 60 km / h is illustrated. For example, bef...

Abstract

A lane change assistance method which: identifies a non-recommended region where no lane changes are recommended, on the basis of road information about the road on which a vehicle is traveling; sets,as a determination area, an area needed for the vehicle to change lanes, on the basis of positional information and vehicle speed information about the vehicle; and, if the determination area includes part or all of the non-recommended region, then determines that the vehicle cannot change lanes, and outputs the determination result.

Description

technical field [0001] The invention relates to a lane change assisting method and a lane change assisting device. Background technique [0002] At present, the following technology is known: the first distance and the first relative speed of the object in front of the host vehicle relative to the lane change target lane of the host vehicle, and the distance of the rear object of the host vehicle relative to the lane change target lane of the host vehicle are detected. The second distance and the second relative speed, and based on the first and second distances and the first and second relative speeds, it is judged whether the vehicle can change lanes (for example, Patent Document 1). [0003] patent documents [0004] Patent Document 1: (Japanese) Unexamined Patent Publication No. 2000-020898 [0005] However, in the prior art, it is only determined based on the relationship between objects in front of and behind the target lane of the lane change of the own vehicle and ...
