CN-121999602-A - Information collection and sharing from crash events

Abstract

Information collection and sharing from collision events is provided. A system and method for collecting evidence of a collision event of a vehicle on a roadway using an observer device is provided. The image sensor captures image data during a collision event. The communication module receives a collision message broadcast from a vehicle involved in a collision event. The evidence collection module processes image data acquired from the image sensor to determine whether a collision event is captured. The evidence collection module also compares time and geographic data from collision messages collected by the involved vehicles during the collision event with time and location metadata in the image data to tag an image of the collision event. When the time and location metadata matches the time and geographic data and the image data captures a collision event, a evidence report is generated that includes a marker image of the collision event.

Description

Information collection and sharing from crash events Technical Field The technical field relates generally to third party devices that collect evidence of collision events, and more particularly to third party devices that detect collisions between nearby vehicles. Background In recent years, advances in vehicle safety technology have been increasingly focused on improving the ability of vehicles to prevent and mitigate collisions. One important area of development is the vehicle-to-everything (V2X) communication system, which allows vehicles to exchange critical information in real-time with other road users and roadside infrastructure equipment. These systems are designed to enhance situational awareness, enabling vehicles to react to potential hazards before they become an impending threat. The primary use case of V2X communication is the transmission of vehicle data between vehicles. In the event of a light collision event, a third party human observer witnessed of the affected vehicle may not feel that the light collision is severe enough to park and does not need to park alongside and share collision event information with other drivers of nearby vehicles. Despite advances in traffic management, challenges remain in reducing traffic associated with light vehicle collisions. The present disclosure provides a method of helping to exchange collected evidence, solving the above-mentioned problems, and the like, by making it faster, safer, and more reliable for all occupants of a vehicle. The desired features and characteristics of the embodiments herein will become apparent from the subsequent detailed description and the appended claims, taken in conjunction with the accompanying drawings and this introduction. Disclosure of Invention In one aspect, the present disclosure provides a system for collecting evidence of a collision event on a roadway with an observer device independent of the vehicle involved therein. The image sensor is configured to capture image data of a road during a collision event. The image data includes time and location metadata. The communication module is configured to receive a collision message broadcast from a vehicle involved in a collision event. The evidence collection module is in communication with the image sensor and includes a processing unit. The processing unit acquires image data from the image sensor and processes the image data to determine whether a collision event is captured. Time and geographic data are obtained from collision messages collected by the involved vehicles during a collision event. The time and location metadata is compared to the time and geographic data to reconcile the image data with the crash event. When (i) the time and location metadata matches the time and geographic data, and (ii) the image data captures a collision event, an evidence report is generated. Evidence reports include images of collision events. In one embodiment, the image sensor, communication module, and evidence collection module may be embodied in a traffic infrastructure platform, wherein the image sensor is positioned proximate to a roadway to acquire image data. In another embodiment, the image sensor, the communication module, and the evidence collection module may be embodied in a witness vehicle in which the image sensor is positioned proximate to the roadway to acquire the image data. In some embodiments, the processing unit may be configured to identify a vehicle of interest captured in the image data in the event of a collision event. The identified vehicles captured in the image data are classified in the event of a collision event based on the vehicle brand, vehicle model, and vehicle color. The vehicle brand, vehicle model, and vehicle color of the identified vehicle are identified based on the collision message. When the vehicle brand, vehicle model, and vehicle color of the identified vehicle are confirmed, an evidence report is transmitted to the vehicle in question. In yet another embodiment, the system described above may include a Human Machine Interface (HMI) in communication with the evidence collection module. The evidence collection module prompts the user at the HMI for a response to verify when the image data is consistent with the collision event. In one embodiment, the communication module transmits the evidence report in response to a request thereto. In another embodiment, the evidence report is transmitted to the involved vehicles based on the collision message. In some embodiments, the processing unit may generate an encrypted evidence report using the public key and transmit the encrypted evidence report to the vehicle in question via the communication link. In yet another embodiment, the processing unit may transmit the encrypted evidence report in response to a request received by the communication module from the vehicle in question. In one embodiment, the system may include a human machine interface in communication with the communicati
