In the present embodiment, places such as intersections and confluences are stored in association with trend information at those places. The description of intersections and merging points in the present embodiment will be given as an example in which the vehicle is traveling on the left side. Therefore, the trend information is different in the example where the vehicle travels on the right side.

Locations and trend information associated with the locations will be described with reference to FIGS. 4 and 5. FIG. FIG. 4 is an example of a table that associates the current position with trend information. FIG. 5 is an example of a table that associates a travel route having the same form as the current position with trend information.

In the table 300 illustrated in FIG. 4, the driving tendency of the user U1 at the A intersection is associated with the first tendency information. The driving tendency of the driver of the other vehicle at the A intersection is associated with the first other vehicle tendency information. Second trend information is associated as the driving trend of the user U1 at the B confluence. As the driving tendency of the driver of the other vehicle at the B junction, the second other vehicle tendency information is associated. Third tendency information is associated with the driving tendency of the user U1 on the C road. Third other vehicle tendency information is associated with the driving tendency of the driver of the other vehicle on the C road.

An example of the first tendency information includes information that the user U1 tends to neglect checking the right side, for example, pedestrians and bicycles on the right side when turning right at the A intersection. An example of the first other vehicle tendency information includes information that many of the drivers of other vehicles tend to be negligent in checking the right side, for example, pedestrians and bicycles on the right side when turning right at intersection A. is Note that the first trend information and the first other vehicle trend information may be different.

It includes information that there is a tendency for bicycles and pedestrians to be neglected. As an example of the third other vehicle tendency information, many drivers of other vehicles, when entering the one-way C road where only right turns are allowed, are likely to see bicycles and pedestrians approaching from the right. It contains information that confirmation tends to be careless. The third trend information and the third other vehicle trend information may be different.

User U1's tendency to check at intersections, junctions, approach roads, etc., tends to be careless due to habits of user U1 and the shape of the vehicle that user U1 is driving. In addition, many types of trend information of drivers of other vehicles include structures that hinder confirmation at intersections, merging points, approach roads, etc. , building around the road, the form of the structure, etc.

A road with a similar shape is, for example, a road that has a similar positional relationship with its surroundings including a road and a sidewalk. A road with a similar shape is, for example, a road in which the shape of the road is similar to that of other roads and the shapes of intersections are similar. A road with a similar shape is, for example, a road with a similar shape at a confluence point between the road and another road. Also, the roads with similar forms are roads with similar structures in the vicinity of the roads, such as the presence and arrangement of structures.

In the table 400 shown in FIG. 5, trend information #A is associated as the driving tendency of the user U1 at the intersection of the same form as the A intersection. Other vehicle tendency information #A is associated with the driving tendency of the driver of the other vehicle at the A intersection.

The tendency information #A includes information about the driving tendency of the user U1 at the intersection of the same form as the A intersection. For example, the trend information #A includes information that, at an intersection of the same form as the intersection A, the user U1 tends to be negligent in checking for pedestrians and bicycles on the right side when turning right. is Other vehicle tendency information #A includes information about the driving tendency of drivers of other vehicles at intersections of the same form as A intersection. For example, in the other vehicle driving tendency information #A, at an intersection of the same type as the intersection A, many drivers of other vehicles neglect to check the right side, for example, pedestrians and bicycles on the right side when turning right. It contains information about trends. The trend information #A and the other vehicle trend information #A may be different.

The warning processor 125 warns the driver. For example, when warning the driver, the warning processing unit 125 outputs a control signal for outputting a warning sound from the audio output unit 50 to the audio guidance control unit 126, so that the audio output unit From 50, a warning is given by voice. In this embodiment, the warning processing unit 125 is described as warning by voice, but the present invention is not limited to this. The warning processing unit 125 may issue a warning visually by, for example, displaying a warning display on a display unit such as a car navigation device. When issuing a visual warning, the warning processing unit 125 may, for example, display a warning display on the side panel in the direction in which the object was detected, out of the side panels for checking the rear left side or the rear right side. In this case, the warning processing unit 125 outputs a control signal for displaying the warning display to the display control unit 127 .

The warning processing unit 125 issues a warning to the driver based on the detection result received from the object detection unit 122 and the trend information received from the trend information acquisition unit 123 . For example, when the object detection unit 122 detects an object within the range corresponding to the trend information acquired by the trend information acquisition unit 123, the warning processing unit 125 issues a warning to the driver.

The voice guidance control unit 126 outputs a control signal for outputting voice to the voice output unit 50 according to the control signal from the warning processing unit 125 . The voice guidance control unit 126 outputs, for example, a control signal for outputting a warning voice to the voice output unit 50 . In this case, the audio output unit 50 issues a warning to the driver by outputting an audio message such as "a bicycle is detected on the rear right side".

The display control section 127 outputs a control signal for displaying an image to the display section 60 . The display control unit 127 outputs a control signal for displaying a map around the current position to the display unit 60 based on the map data 21 and the current position acquired by the current position information acquiring unit 120, for example. The display control section 127 may output a control signal to the display section 60 for displaying a warning display on the display section 60 in accordance with the control signal from the warning processing section 125 . The display control unit 127 may output a control signal for displaying a warning display to the side panel for checking the left rear or right rear according to the control signal from the warning processing unit 125 .

Processing of the control unit 100 will be described with reference to FIG. FIG. 6 is a flowchart showing an example of the processing flow of the control unit 100. As shown in FIG.

You may acquire both the trend information of And the control part 100 progresses to step S102.

The control unit 100 determines whether or not the current position is a warning target point (step S102). A warning target point is a point that is recorded in the tendency information of the driver of the vehicle M or of a plurality of other vehicles as having a tendency to be neglected in confirmation. If the current position is determined to be the warning target point (Yes in step S102), the control unit 100 proceeds to step S103. On the other hand, when it is determined that the current position is not the warning target point (No in step S102), the control unit 100 proceeds to step S106.

At step S103, the control unit 100 determines whether or not an object requiring a warning has been detected (step S103). If it is determined that an object requiring warning has been detected (Yes in step S103), the control unit 100 proceeds to step S104. On the other hand, if it is determined that an object requiring warning has not been detected (No in step S103), the control unit 100 proceeds to step S106. Objects requiring warning include other vehicles, bicycles, and pedestrians.

At step S104, the control unit 100 determines whether or not the detected object is within a range requiring a warning (step S104). If it is determined that the warning is required (Yes in step S104), the control unit 100 proceeds to step S105. On the other hand, if it is not determined that the warning is required (No in step S104), the control unit 100 proceeds to step S106.

At step S105, the control unit 100 executes warning processing to the driver of the vehicle M (step S105). Then, the control unit 100 proceeds to step S106.

At step S106, the control unit 100 determines whether or not the driving assistance has ended (step S106). When it is determined that the driving assistance has ended (Yes in step S106), the control unit 100 ends the processing of FIG. On the other hand, if it is not determined that the driving support has ended (No in step S106), the control unit 100 proceeds to step S101 and executes the above-described processing.

The processing of FIG. 7 differs from the processing of FIG. 6 in that it is confirmed that the current position is a point similar to the warning target point as trend information. In the flowchart of FIG. 7, the processing from step S201 and from step S203 to step S206 is the same as the processing from step S101 and step S103 to step S106 in the flowchart of FIG.

Based on the current position and the map information, the control unit 100 determines whether the current position is a point having the same form as the warning target point, that is, whether or not it is a traveling road (step S202). In step S202, the control unit 100 may make a determination based on the tendency information of the driver of the vehicle M, or may make a determination based on the tendency information of the drivers of a plurality of other vehicles. Then, the control unit 100 proceeds to step S203.

As described above, in this embodiment, based on the driving tendency of the driver who drives the vehicle or the driver of another vehicle, points where confirmation tends to be neglected, and points where confirmation tends to be neglected Warnings can also be given at similar points. As a result, according to the present embodiment, it is possible to issue an appropriate warning at an intersection or the like where confirmation of people, two-wheeled vehicles, other vehicles, etc. tends to be neglected. As a result, this embodiment can improve safety.

Specifically, in this embodiment, an appropriate warning can be given to each driver based on his or her own driving tendency. This makes it possible to further improve safety.

In this embodiment, based on the driving tendencies of other vehicles, it is possible to issue an appropriate warning to the driver even on a road that the driver is traveling on for the first time. Moreover, more appropriate warning can be given based on the tendency information of many other vehicles. This makes it possible to further improve safety.

The motion detection unit 70 outputs the detected motion information to the motion information acquisition unit 128 .

In this embodiment, the motion detection unit 70 is, for example, a line-of-sight sensor that detects the line-of-sight direction of the driver. In this case, the motion detector 70 is arranged to face the driver. If the motion detection unit 70 is a line-of-sight sensor, it is preferably arranged on both sides in order to detect visual gaze to the left rear or right rear of the vehicle. The motion detection unit 70 includes, for example, an infrared light emitting device and an infrared light camera, irradiates the driver's face with infrared light, and receives image data captured by the infrared light camera as the motion information acquisition unit 128. output to Another example of the motion detection unit 70 is a visible light camera that captures the driver's face, and outputs captured image data to the motion information acquisition unit 128 . In this case, the motion detection unit 70 detects the direction of the driver's face. In the following description, the motion detection unit 70 detects the driver's line of sight direction, but this is an example and does not limit the present invention.

The motion information acquisition unit 128 acquires the motion information of the driver from the motion detection unit 70 . The motion information acquisition unit 128 acquires the motion information of the driver, for example, when the vehicle is positioned at an intersection or junction. The motion information acquisition unit 128 acquires the direction of the line of sight of the driver when the vehicle is positioned at an intersection or junction as motion information. The motion information acquisition unit 128 outputs the acquired motion information to the trend information acquisition unit 123 .

The trend information acquisition unit 123 acquires trend information based on the motion detection result including the driver's motion information received from the motion information acquisition unit 128 . Based on the motion detection result including the driver's motion information received from the motion information acquisition unit 128, the trend information acquisition unit 123 tends to fail to confirm whether or not the driver has an object at the current position.

In step S303, the control unit 100A generates trend information including a range in which the driver tends not to confirm whether or not there is an object at the current position, based on the motion detection result including the driver's motion information. get. The control unit 100A may acquire trend information including a range in which the driver tends to be unable to confirm whether or not there is an object on a travel path that has the same form as the current position. Then, the controller 100A proceeds to step S304. The acquisition of trend information in step S303 acquires, as trend information, for example, a state in which the driver's line of sight is not directed toward the rear view mirror or the driver is not performing an action such as looking to the side or rear. As for the trend information, when turning at an intersection, the trend information of the direction requiring confirmation corresponding to the turning direction may be acquired. Similarly, at a confluence point, trend information may be obtained for a direction requiring confirmation corresponding to the confluence direction.
