- FIG. 1 is an overall configuration diagram of a vehicle event occurrence detection system according to an embodiment of the present invention
- FIG. 3 is a view showing an example of the image labeling apparatus of the present invention.
- FIG. 4 is a view showing a data structure of a storage unit of the vehicle control unit of the present invention.
- 6A and 6B are views showing an example of another image display device of the present invention.
- One of the features of the embodiments of the present invention described below is that it is possible to analyze the reason for the accident and the situation before and after the accident by determining whether an event occurs based on the “distance” and the “relative speed” between vehicles. have.
- Vehicle in the present invention should be interpreted as broadly as possible to include a two-wheeled vehicle such as a motorcycle, as well as a four-wheeled mobile device such as a passenger car, bus, or truck.
- the vehicle event occurrence detection system 1 includes a vehicle control unit 10 mounted on a vehicle, a central server 20 and a mobile device 30 communicating with the vehicle control unit 10, and an external communicating with the central server 20.
- Device 50 The central server 20 and the mobile device 30 are separate devices independent of the vehicle.
- the external device 50 is optional as illustrated by a dotted line, and it can be said that it is not an essential configuration of the present invention.
- the vehicle control unit 10 includes an event occurrence determination unit 12, a display control unit 14, and a storage unit 16.
- the vehicle control unit 10 is provided to the vehicle as an independent module.
- the event occurrence determination unit 12 is connected to various sensors and imaging devices mounted in the vehicle.
- the display control unit 14 is connected to a driver of each image device to control a head-up display device mounted on a vehicle, a black box, a room mirror, a dashboard, navigation or a TV installed in the vehicle.
- the storage unit 16 is preferably a dedicated memory allocated to the vehicle control unit 10.
- the event occurrence determination unit 12 analyzes the vehicle information around the current vehicle and determines whether an accident is possible or latent as an “event”. Specifically, as illustrated in FIG. 2, the event occurrence determination unit 12 first detects whether a vehicle traveling on the same road based on the current vehicle is within a predetermined range, for example, 30 meters (S10).
- the recognition means may be various sensors and image pick-up devices mounted on a vehicle, for example, a speed sensor, a radar, a radar, a laser, an optical camera, an ultrasonic sensor, or a GPS. Since these devices are actually used to obtain surrounding information in smart cars and autonomous vehicles, it is advantageous to implement the vehicle control unit 10 of the present invention.
- the event occurrence determination unit 12 calculates the speed and distance of each object on an object within a range detected by the recognition means (S12), and determines an object to be monitored (S14). Specifically, the event occurrence determination unit 12 determines a vehicle in front of the closest distance as a first monitoring target. In addition to this, the vehicle with the closest distance is determined as the second monitoring target. If this decision is made, it is possible to prevent an accident in advance and accurately record the occurrence of the accident by monitoring front and rear vehicles having the highest risk of occurrence. It is determined that the event has occurred by the event occurrence determination unit 12 determining the vehicle to be monitored.
- the event occurrence determination unit 12 determines the first monitoring target when the relative speed with the current vehicle is greater than or equal to the current vehicle as the vehicle in front of the closest distance, and the vehicle with the current vehicle as the vehicle behind the closest distance.
- the relative speed of is greater than or equal to a predetermined value, it can be determined that the “event” has occurred by determining this as the second monitoring target.
- the relative speed is higher than a predetermined value, it means that there is a fear of collision or collision due to a large speed difference from the host vehicle due to overspeed, rapid deceleration, or sudden braking. If it is judged by adding a relative speed criterion, unnecessary event occurrence can be reduced to reduce the system load.
- Vehicle accidents occur for various reasons and, for example, even when another vehicle suddenly intervenes in an adjacent lane, it is effective to acquire the information of the vehicle “front” and “rear” because it is eventually captured by the front or rear recognition means.
- the event occurrence determination unit 12 is a reference criterion for an object to be monitored, based on a physical distance from another vehicle occupying the same road as the current vehicle, and further, the relative speed is secondary. It determines whether an event has occurred based on the criteria, so it is possible to accurately detect a vehicle that may have an accident.
- the event occurrence determination unit 12 sets the relative speed with other vehicles occupying the same road as the current vehicle as the primary reference, and the distance as the secondary reference as the criteria for determining the object to be monitored. It is also possible to change to determine whether or not. In this case, the order of priority determination criteria is changed, but the vehicle to be monitored will be the same as the previous embodiment.
- the host vehicle information and the vehicle information to be the first and second monitoring objects are stored in the storage unit 16 in real time.
- the vehicle information preferably includes identifiable vehicle license plate information and location information in addition to distance and speed information over time.
- the display control unit 14 generates image data based on the own vehicle and monitoring target vehicle information transmitted from the storage unit 16, and transmits the image data to the storage unit 16 at the same time as the head-up display device, the black box, the room mirror, Transmit to the instrument panel, navigation or TV installed in the vehicle.
- the storage unit 16 may generate and store image data and simultaneously transmit the image data to the display control unit 14.
- the storage unit 16 stores information of the vehicle to be monitored as so-called “character” and “image” data 162,164 as shown in FIG. 4.
- the storage unit 16 is a removable device, inserting it into an electronic device such as a PC, tablet or black box can analyze the situation before and after an event or accident.
- the “image” in the present invention includes still image data as well as moving image data, and should be interpreted as broadly as possible.
- FIG. 3 is a view showing an example of displaying image data on a windshield glass 140 of a vehicle as a head-up display connected to the display control unit 14.
- the first monitoring target vehicle 142a in front and the second monitoring target vehicle 146a in the rear are displayed as images, centering on their current vehicle 144.
- the difference from the known head-up display is that it does not show all or a significant range of front vehicles of the current vehicle, which can reduce the load on the system, and only the vehicle closest to the current vehicle is extracted and displayed. The possibility of accidents can be reduced by ventilating.
- Vehicle speed information 142b and distance information 142c are displayed together under the first monitoring target vehicle 142a, and vehicle speed information 146b and distance information 146c are displayed below the second monitoring target vehicle 146a. Is displayed together.
- the vehicle speed information 142b, 146b of the first and second monitored vehicles 142a, 146a is a criterion for accurately determining whether the vehicle is due to overspeed or sudden deceleration or sudden braking when a collision or collision occurs. If the distance is “0”, the accident occurred for any reason.
- text and image data stored in the storage unit 16 in a state where the distance is “0” becomes data that can analyze the situation after the accident. As is well known to those skilled in the art, by using the data of the collision detection sensor or the black box, it is possible to analyze whether the accident occurred and the information before and after the accident as a whole.
- FIG. 3 shows the head-up display as an example, and various other modifications are possible as follows;
- the vehicle in front of the vehicle may display a vehicle projected on an actual windshield glass and display speed and distance information, instead of displaying it as an image.
- the display means for example, the vehicle to be monitored can be displayed on the screen of the navigation device.
- the speed and distance may be displayed while actually showing the vehicle to be monitored through the rearview mirror as shown in FIG. 6A.
- speed and distance information of the first monitoring target vehicle may be displayed in red on the left side of the panel of the speed dashboard, and speed and distance information of the second monitoring target vehicle may be displayed in red on the right side.
- the driver can easily recognize the front and rear vehicle information as well as the speed information of the host vehicle displayed in the center.
- the image display of the vehicle to be monitored can be omitted.
- the vehicle in the embodiment of the present invention includes, for example, a police officer's enforcement vehicle, as well as a case where the general driver boards, and is capable of speeding and accident prevention activities.
- the mobile device 30 is connected to the vehicle control unit 10, specifically, characters stored in the storage unit 16 and “image” data 162 and 164 are used by the user. It is transmitted to a mobile device 30 such as a mobile phone.
- An application for receiving data from the storage unit 16 and executing a predetermined program is installed in the mobile device 30. When the user runs the application, surrounding vehicle information is displayed on the screen of the mobile device 30 similarly to FIG. 3.
- FIG. 5 shows an example of the first monitoring target in front of the current vehicle 304 in the boundary lines 310a and 310b of the road currently being driven on the screen 300 of the mobile device 30.
- the vehicle 302a and the rear second target vehicle 306a are displayed as images.
