Description

Technical Field

[0001] The present invention relates to the field of V2X technology, and in particular to a V2X-based quick solution and system for minor collision accidents. Background Art

[0002] V2X (Vehicle-to-X) refers to the communication between vehicles and surrounding equipment. X includes vehicles, roadside facilities, service stations, etc. At present, its wireless communication technology follows the IEEE802.11P protocol, and is designed to have a transmission distance of 300-1000m and a transmission rate of 3M-27Mbps. The advantages of V2X communication compared with 3G / 4G are high real-time transmission, no need for base stations, and no need for operator traffic and charging issues. V2X is mainly used in the fields of intelligent transportation and active driving safety to reduce traffic accidents and improve traffic efficiency. V2X's communication technology mainly adopts WAVE (Wireless Access in Vehicular Environments) self-organizing network communication, which has good flexibility and is very suitable for highly mobile vehicle environments. The physical layer adopts the IEEE802.11P protocol and uses the 5.9GHZ wireless communication frequency band; the data link layer, transport layer and above transmission standards adopt the IEEE1609 protocol group.

[0003] RSU is a hardware unit installed on the roadside that can realize V2X communication and support V2X applications. The working frequency band is 5.905-5.925GHz, the communication distance can reach 1000 meters in open road conditions, and 500-800 meters in urban environments. It supports differential high-precision positioning, GPS dual-mode positioning and other positioning systems. At the same time, it is equipped with cameras, laser radars, etc. to monitor the environment of the car in real time, and the comprehensive output can make correct judgments for users' safe driving.

[0004] With the development of society and the improvement of people's living standards, vehicles have become an indispensable means of transportation for outdoor travel. On the one hand, the current number of vehicles is growing rapidly. On the other hand, road construction is changing with each passing day, and road conditions are becoming increasingly complicated. When vehicles are driving at busy intersections, with many vehicles and complex road conditions, it is difficult to ensure that drivers will not have traffic accidents on the road. When a traffic accident occurs on urban roads, especially on peak-hour roads, drivers usually get off the car to take pictures, call the police, and negotiate with the other vehicle to solve the problem. This not only wastes time, but also causes traffic congestion and has a great impact on traffic. In addition, there may be hit-and-run situations and property losses caused by hit-and-run. Therefore, there is an urgent need for simple and quick handling of traffic accidents to quickly solve the traffic congestion phenomenon.

[0005] In the current context where RSUs are widely deployed at intersections with heavy traffic, in order to quickly resolve this problem, vehicles equipped with V2X can interact with RSUs when a collision occurs to obtain accurate information about the traffic accident, thereby determining whether the vehicle can quickly leave the lane and stop on the roadside without affecting the continued passage of other vehicles. Summary of the invention

[0006] In order to overcome the problem in the above-mentioned prior art that when a traffic accident occurs on the road, the driver has to get off the vehicle to take photos, call the police, and negotiate with the other vehicle to solve the problem, which not only wastes time but also causes traffic congestion and has a great impact on traffic.

[0040] Example 1

[0041] The present embodiment discloses a quick solution to a minor collision accident based on V2X. In the context of roadside units RSU being arranged in a large area at intersections with heavy traffic, and vehicles being equipped with onboard units OBU, when a collision occurs, a photo request can be sent to the roadside unit RSU at the first time, requesting the roadside unit RSU to take photos of the collision scene from multiple directions, and sending the photos to the onboard unit OBU of the corresponding vehicle. After confirming receipt of the photos, the onboard unit OBU of the vehicle displays the photos through a display unit. When the driver confirms that the photos are available, the onboard unit OBU of the vehicle sends the photos to the roadside unit RSU. SU sends a confirmation message, and quickly leaves the lane and stops on the roadside without affecting the continued passage of other vehicles. If the other vehicle is also equipped with an on-board unit OBU, it will also send a confirmation message to the roadside unit RSU after taking the same measures. After receiving the confirmation message from both parties of the accident, the roadside unit RSU can assist in reporting the incident to the police and notify the insurance company. In this case, the vehicle can leave the scene directly; this solves the problem that when a vehicle collides, it relies on manual photography, calling the police, and negotiating with the other vehicle to solve the problem, which not only wastes time, but also causes congestion and has a great impact on traffic.

[0042] Therefore, the method of this embodiment is based on an onboard unit OBU installed on a vehicle and a roadside unit RSU installed on a roadside, and the onboard unit OBU and the roadside unit RSU are connected via V2X communication. Figure 1 As shown, the following steps are included:

[0043] S10. When a vehicle collision occurs, the on-board unit OBU sends a unicast message to the roadside unit RSU.

[0044] In this step, vehicles equipped with on-board units OBU have V2X-based wireless communication capabilities and can send unicast messages to roadside units RSU.

[0045] Based on this embodiment, the unicast message sent is a photo-taking request.

[0046] Therefore, this step specifically includes: when a vehicle equipped with an on-board unit OBU collides at an intersection, the on-board unit OBU immediately sends a photo request to the roadside unit RSU through V2X.

[0047] S20. After receiving the unicast message sent by the on-board unit OBU, the roadside unit RSU obtains photos of the collision scene according to the unicast message, and unicasts the obtained photos to the on-board unit OBU of the corresponding vehicle.

[0048] In this step, the roadside unit RSU has positioning and photo taking functions, and can also unicast to the requesting vehicle.

[0049] Therefore, this step specifically includes:

[0050] After receiving the photo request sent by the on-board unit OBU, the roadside unit RSU parses the request instruction, locates the location of the vehicle through the positioning function, takes multi-directional photos of the vehicle's location through the photo function, performs specific processing on the collision location, and broadcasts the taken photos to the on-board unit OBU of the corresponding vehicle.

[0051] In this step, the photos taken specifically include: taking photos of the four directions of the vehicle, front, back, left, and right, and taking high-definition close-ups of the collision position, so that the accident status and the collision position are clearly visible.

[0052] In this step, the number of photos is determined according to the severity of the collision accident. Generally, photos of the vehicle from the front, back, left, and right sides as well as high-definition close-up photos of the collision location are sufficient.

[0053] S30. After the vehicle's onboard unit OBU confirms receipt of the photo, it displays it to the driver through the display unit.

[0054] In this step, the display unit includes an HMI device, a dashboard, a HUD display, or other displayable locations, such as projecting onto a front windshield.

[0055] Therefore, this step specifically includes:

[0056] After the vehicle's on-board unit OBU confirms receipt of the photo, it displays it on the HMI device, instrument panel or HUD through the vehicle body CAN bus, making it convenient for the driver to confirm.

[0057] S40. The driver determines whether the photo is available. If not, the on-board unit OBU resends the unicast message to the roadside unit RSU; if available, the on-board unit OBU sends a confirmation message to the roadside unit RSU, and sends the photo to the driver's mobile terminal at the same time, and the driver drives the vehicle away from the scene.

[0058] In this step, the driver will determine whether the photo displayed on the HMI device, instrument panel or through the HUD is available and proceed to the next step.

[0059] Therefore, this step specifically includes:

[0060] The driver determines whether the photo is available. If not, the on-board unit OBU resends the unicast message to the roadside unit RSU through V2X, and returns to step S10; if available, the on-board unit OBU sends a confirmation message to the roadside unit RSU through V2X. The on-board unit OBU also sends the photo to the driver's mobile terminal through the 4G\5G mobile network for easy retention. After receiving the photo, the driver drives the vehicle away from the scene to reduce the burden of road congestion.

[0061] In this embodiment, the vehicle includes a collision vehicle and / or a scraping opposite-end vehicle, that is, a single-party vehicle or both parties of the accident.

[0062] When the vehicle includes a collision vehicle and / or a collision with an opposite vehicle, specifically, a vehicle equipped with an on-board unit OBU collides with a vehicle not equipped with an on-board unit OBU or other motor vehicles.

[0063] As a preferred embodiment, the vehicles include a collision vehicle and a collision opposite-end vehicle, that is, vehicles on both sides of the accident.

[0064] Therefore, this embodiment also includes the steps of:

[0065] S50. After receiving confirmation messages from both the collision vehicle and the other vehicle, the roadside unit RSU assists in reporting the accident to the police and notifies the insurance company to handle the collision accident.

[0066] That is, after executing step S30, the drivers of the vehicles on both sides of the accident determine that the photos are available, and then send a confirmation message to the roadside unit RSU. After receiving the confirmation messages from the vehicles on both sides of the accident, the roadside unit RSU can assist in filing an alarm and notify the insurance company. In this case, the vehicles can leave the scene directly.

[0067] This embodiment not only quickly resolves the collision accident and avoids traffic congestion, but also avoids the possibility of hit-and-run.

The on-board unit OBU is communicatively connected with the roadside unit RSU, the display unit and the mobile terminal respectively.

[0071] In this embodiment, the on-board unit OBU is used to send unicast messages to the roadside unit RSU, receive photos of the collision site unicast by the roadside unit RSU, send photos to the display unit for display, and send photos to the driver's mobile terminal.

[0072] The roadside unit RSU is used to receive the unicast message sent by the on-board unit OBU, obtain the collision scene photo according to the unicast message, and unicast the obtained photo to the on-board unit OBU of the corresponding vehicle.

[0073] The display unit is used to display the collision scene photos received by the on-board unit OBU.

[0074] The mobile terminal is used to receive and store photos sent by the on-board unit OBU after the driver determines that the photos are available; the mobile terminal includes a mobile phone, a tablet computer, etc. bound to the car owner.

[0076] S10. When a vehicle collision occurs, the on-board unit OBU sends a unicast message to the roadside unit RSU.

[0077] S20. After receiving the unicast message sent by the on-board unit OBU, the roadside unit RSU obtains photos of the collision scene according to the unicast message, and unicasts the obtained photos to the on-board unit OBU of the corresponding vehicle.

[0078] S30. After the vehicle's onboard unit OBU confirms receipt of the photo, it displays it to the driver through the display unit.

[0079] S40. The driver determines whether the photo is available. If not, the on-board unit OBU resends the unicast message to the roadside unit RSU; if available, the on-board unit OBU sends a confirmation message to the roadside unit RSU, and sends the photo to the driver's mobile terminal at the same time, and the driver drives the vehicle away from the scene.

[0080] S50. After receiving confirmation messages from both vehicles, the roadside unit RSU assists in reporting the accident to the police and notifies the insurance company to handle the collision accident.
