Problems solved by technology

[0004] In this case, for example, a branch road is connected ahead of the driving lane, and if the dividing line is interrupted by the branching road, the dividing line cannot be detected, so it is difficult to set the target travel route, and the lane keeping control is canceled.

Embodiment Construction

[0031] Hereinafter, one embodiment of the present invention will be described based on the drawings. figure 1 The driving assistance system 1 shown is mounted on the own vehicle M (refer to Figure 7 ~ Figure 11 ). This driving assistance system 1 is equipped with a navigation unit 11 that sets the current position of the host vehicle M (host vehicle position) and a current position until driving, a camera unit 21 as a running environment information acquisition mechanism, and a lane keeping control unit 22 . The driving route to the destination set by the operator.

[0032] The navigation unit 11 estimates the current position of the own vehicle M on the road map (own vehicle position), and sets a traveling route up to the destination set by the driver based on the road map data. On the other hand, the camera unit 21 acquires the driving environment information in front of the host vehicle M, recognizes the left and right dividing lines dividing the driving lane, the road ...

Abstract

The invention provides a lane keeping control device which can obtain stable lane keeping controllability by detecting interruption of a dividing line early without misjudgment under the condition that the dividing line of a driving path of a vehicle is interrupted. A lane keeping control calculation unit (22c) detects that a preceding vehicle (D) is traveling in front of a lane in which the hostvehicle (M) is traveling (S23) and that a turn light of the preceding vehicle (D) is flashing (S24). A lane change range ([Delta] W) indicating the expansion of the dividing line is compared with a second expansion determination threshold ([Delta] WL) (S29), and when the expansion ([Delta] W > = [Delta] WL) of the dividing line is detected, a target travel path (1 / 2 of the lane width (W)) is set with reference to the dividing line on the opposite side of the flashing turn light (S32).

Description

technical field [0001] The present invention relates to a lane keeping control device for setting a target travel path with reference to a dividing line on the opposite side of the flashing turn signal when the turn signal of a preceding vehicle is detected to be flickering and the width of the lane is widened. Background technique [0002] In the car navigation system mounted on the vehicle (own vehicle) driven by the driver, after the driver sets the destination, the navigation system is based on GNSS (Global Navigation Satellite System: Global Navigation Satellite System) satellites represented by GPS satellites, etc. The location information of the vehicle is detected by the position information received by the positioning satellite, and the driving route from the location of the vehicle to the destination is set by matching with the road map information. Then, the host vehicle is guided to the destination along the traveling route. [0003] At this time, when the vehic...
