Abstract

PROBLEM TO BE SOLVED: To predict danger that an own vehicle enters into a blind corner of other vehicle, and issue a warning to drivers of the own vehicle and the other vehicle.SOLUTION: A vehicle body 4 of a two-wheel vehicle 2 is equipped with an on-vehicle camera 5 for photographing other vehicle 3 in front and a display part 6 for displaying an image photographed by the on-vehicle camera 5. A helmet 7 of a driver D is equipped with an intercom 8 with a speaker for emitting a warning sound. An electronic control device 11 of the two-wheel vehicle 2 comprises: an image processing section 12 for calculating a blind corner area A formed by the other vehicle 3 from image data of the on-vehicle camera 5; a storage section 13 for storing an operation parameter; a control section 14 for outputting a warning command when the own vehicle 2 enters into the blind corner area A; a warning section 15 for triggering the intercom 8 according to the warning command; and a communication section 16 for transmitting the warning command to the other vehicle 3 by means of inter-vehicle communication.

Description

  The present invention relates to a system for predicting a collision between a host vehicle and another vehicle, and more particularly to a vehicle risk prediction system for predicting a danger associated with the host vehicle entering a blind spot of another vehicle.

  Each part around the vehicle has blind spots that the driver cannot see. For example, there is a blind spot on the side of the vehicle that is not reflected on the side mirror, and there is a danger of contact or collision when turning left or changing course. Two-wheeled vehicles in particular are easy to enter blind spots created by other vehicles because of their small body and high speed.

  Therefore, conventionally, a system for detecting another vehicle that has entered the blind spot of the host vehicle has been proposed. For example, Patent Document 1 describes a system in which a blind spot area is set around the host vehicle, and the driver is informed of the danger when another vehicle stays in this area for a predetermined time.

  However, according to the conventional system, even if the other vehicle that has entered the blind spot of the host vehicle can be detected, there is a risk that the host vehicle will enter the blind spot of the other vehicle, for example, the motorcycle enters the blind spot of the large vehicle at the intersection. There was a problem that motorcycle drivers could not predict the danger.

  Therefore, an object of the present invention is to provide a system capable of predicting the danger of the host vehicle entering the blind spot of another vehicle and generating a warning to the driver.

  In order to solve the above-described problems, a vehicle danger prediction system according to the present invention obtains a blind spot area formed by another vehicle from an in-vehicle camera that captures the other vehicle traveling around the host vehicle and video data of the in-vehicle camera. The image processing means and control means for performing control for generating a warning to the driver of the host vehicle when the host vehicle enters the blind spot area.

  Here, in order to easily calculate the blind spot area in the video data, the video processing means sets a warning area in the video data of the in-vehicle camera to watch for the approach of the host vehicle and other vehicles, and in the warning area Data processing is performed to change the area of the blind spot area according to the size of other vehicles in the vehicle.

  Moreover, in order to avoid the danger of a collision reliably, a control means performs control for transmitting a warning command to another vehicle by inter-vehicle communication when the host vehicle enters the blind spot area.

  According to the vehicle danger prediction system of the present invention, a blind spot area of another vehicle is obtained from the video data of the in-vehicle camera, and a warning is generated when the own vehicle enters this area. It has the effect of predicting the danger of entering.

1 is an overview diagram of a vehicle danger prediction system showing an embodiment of the present invention. It is a screen figure of the display part which shows the alert area set in video data. It is a screen figure of the display part which shows the scene where the other vehicle is drive | working the distant place of the own vehicle. It is a screen figure of the display part which shows the scene where other vehicles are running near the own vehicle. It is a top view of the intersection which shows the scene where the own vehicle approached into the blind spot area of the other vehicle.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The vehicle danger prediction system 1 shown in FIG. 1 is configured so that the driver D of the two-wheeled vehicle 2 can predict the risk that the two-wheeled vehicle (own vehicle) 2 enters the blind spot of the other vehicle 3. Alternatively, the danger prediction system of the present invention may be mounted on a four-wheeled vehicle so that the driver of the four-wheeled vehicle can predict the danger that the four-wheeled vehicle will enter the blind spot of a large vehicle such as a truck. .

  A vehicle body 4 of the two-wheeled vehicle 2 is provided with an in-vehicle camera 5 that captures another vehicle 3 that is traveling in front of the host vehicle, and a display unit 6 that displays an image captured by the in-vehicle camera 5. As the display unit 6, a display of a car navigation system can be used. The helmet 7 worn by the driver D of the two-wheeled vehicle 2 is equipped with an income 8 having a speaker that generates a warning sound.

  The electronic control device 11 of the motorcycle 2 includes a video processing unit 12 that calculates a blind spot area A formed by the other vehicle 3 from video data of the in-vehicle camera 5, a storage unit 13 that stores calculation parameters, and a blind spot area A. A control unit 14 that outputs a warning command when the vehicle 2 enters, an alarm unit 15 that drives the income 8 according to the warning command, and a wireless communication unit 16 that transmits the warning command to the other vehicle 3 by inter-vehicle communication are provided. It has been.

  As shown in FIG. 2, the video processing unit 12 includes a pair of warning areas S <b> 1 and S <b> 2 for warning the approach of the host vehicle 2 and the other vehicle 3 in addition to the video of the in-vehicle camera 5 on the screen 6 a of the display unit 6. Is displayed. The warning areas S1 and S2 are divided on the left and right of the vertical line (V-V) passing through the center of the motorcycle 2 by a horizontal line (HH) assuming a road surface and a diagonal line 60 ° from the center point (O). And is stored in advance in the storage unit 13 as fixed data indicating the position of the host vehicle.

  On the other hand, as shown in FIG. 3, the other vehicle 3 is displayed on the screen 6a as an image whose size changes according to the distance from the host vehicle. The video processing unit 12 calculates the size of the other vehicle 3 occupying the warning area S2 from the video data of the in-vehicle camera 5, and changes the area of the blind spot area A according to the calculated value. Then, as shown in FIG. 4, when the own vehicle 2 enters the blind spot area A in a state where the size of the other vehicle 3 occupying the warning area S <b> 2 exceeds the specified value, the control unit 14 Control for generating a warning to the driver of the other vehicle 3 is performed.

  Therefore, for example, as shown in FIG. 5, when the other vehicle 3 turns left at the intersection in front of the two-wheeled vehicle 2 and the two-wheeled vehicle 2 enters the blind spot area A of the other vehicle 3, the income sound is immediately generated by the income 8. At the same time, a sound or light alarm is generated even in the driver's seat of the other vehicle 3 by inter-vehicle communication. For this reason, the driver D of both the own vehicle 2 and the other vehicle 3 can predict a danger and can avoid a collision beforehand. The danger prediction system 1 of this embodiment can also be used for safety confirmation when the lane of the other vehicle 3 is changed or when the two-wheeled vehicle 2 passes through the side.
