Description

Technical Field

[0001] This invention relates to the field of V2X communication technology, and in particular to a V2X-based intelligent driving vehicle collision avoidance detection system. Background Technology

[0002] V2X, or vehicle-to-everything (V2X), integrates positioning and navigation technologies, vehicle-to-vehicle communication technologies, wireless communication, and remote sensing technologies, laying the foundation for a new direction in automotive technology development. It achieves compatibility between manual and autonomous driving. Simply put, vehicles equipped with this system can automatically select the best route in autonomous driving mode by analyzing real-time traffic information, thus greatly alleviating traffic congestion. Furthermore, by using onboard sensors and camera systems, it can perceive the surrounding environment and make rapid adjustments, thereby achieving "zero traffic accidents." V2X is a key technology for future intelligent transportation systems, enabling communication between vehicles, between vehicles and base stations, and between base stations. This allows for the acquisition of real-time traffic conditions, road information, pedestrian information, and other traffic data, thereby improving driving safety, reducing congestion, increasing traffic efficiency, and providing in-vehicle entertainment information.

[0003] Intelligent driving essentially involves cognitive engineering of attention attraction and distraction, mainly comprising three stages: network navigation, autonomous driving, and human intervention. The prerequisites for intelligent driving are that the selected vehicle meets the dynamic requirements of driving, the onboard sensors can acquire relevant visual and auditory signals and information, and the corresponding servo system is controlled through cognitive computing. Network navigation in intelligent driving solves problems such as where we are, where we are going, and which lane we are on which road. Autonomous driving, under the control of the intelligent system, completes driving behaviors such as lane keeping, overtaking and changing lanes, stopping at red lights and proceeding at green lights, and interacting with traffic signals. Human intervention refers to the driver reacting appropriately to actual road conditions based on a series of prompts from the intelligent system.

[0004] Intelligent driving is essentially a cognitive engineering process involving attention attraction and attention distraction, and mainly includes three aspects: network navigation, autonomous driving, and human intervention.

[0005] The automotive collision avoidance warning system is based on intelligent video analysis and processing. It achieves its warning function through dynamic video camera technology and computer image processing technology. Its main functions include: distance monitoring and rear-end collision warning, forward collision warning, lane departure warning, navigation function, and black box function. Compared with existing automotive collision avoidance warning systems at home and abroad, such as ultrasonic collision avoidance warning systems, radar collision avoidance warning systems, laser collision avoidance warning systems, and infrared collision avoidance warning systems, it has unparalleled advantages in terms of function, stability, accuracy, user-friendliness, and price. It can operate stably in all weather conditions for a long time, greatly improving the comfort and safety of driving.

[0006] In practical use, existing automotive collision avoidance warning systems typically do not utilize V2X communication systems. This results in vehicles being unable to react and brake in time when a "ghost peeks out" from ahead, leading to collisions and lower safety. Summary of the Invention

[0007] This invention provides a V2X-based intelligent driving vehicle collision avoidance detection system, which solves the problem that existing car collision avoidance warning systems do not utilize the V2X communication system in actual use, resulting in the vehicle being unable to react and brake in time when a "ghost peeks out" appears in front, thus causing a collision and resulting in low safety.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: The V2X-based intelligent driving vehicle collision avoidance detection system includes an interior rearview mirror housing and a connector. The connector includes a connecting block, a connecting rod fixed to the outer wall of the connecting block, and a connecting ball fixed to the bottom outer wall of the connecting rod. The connecting rod is equipped with a detection mechanism, which includes a mounting block with four mounting holes on one side of its outer wall, two laser rangefinders respectively embedded in two of the mounting holes, and two millimeter-wave radars respectively embedded in the other two mounting holes.

[0010] Preferably, a fixing block is fixed on the outer wall of the mounting block located above the connecting rod on one side, and the fixing block is connected to the top outer wall of the connecting rod by bolts.

[0011] The above solution integrates a laser rangefinder and a millimeter-wave radar into the rearview mirror assembly of an intelligent driving vehicle. Meanwhile, the positions of the laser radar, millimeter-wave radar, and infrared sensors on the vehicle body remain unchanged. During intelligent driving, the two laser rangefinders and two millimeter-wave radars detect the distance to the vehicle ahead. Simultaneously, the system analyzes images captured by the driving recorder camera to determine the vehicle's trajectory and type. The system then uses a V2X communication module to communicate with the vehicle ahead, base stations, and other information carriers to obtain the vehicle's driving data.

[0014] Preferably, the image analyzer, data analyzer, and VX communication module are respectively bolted to the outer wall of one side of the mounting plate.

[0015] Preferably, an acrylic plate is embedded in the inner wall of the rearview mirror housing on the side away from the rearview display screen, and the acrylic plate is connected to the rearview mirror housing by sealant.

[0016] Preferably, the driving image display screen is used to display the image in front of the intelligent driving vehicle, the decision display screen is used to analyze whether the current vehicle needs to perform active braking and display the decision result, and the rear view display screen is used to display the image behind the intelligent driving vehicle.

[0017] Preferably, the image analyzer is connected in series with the camera via a signal line, and the data analyzer is connected to the camera via a data line. The image analyzer and the data analyzer are respectively connected to the decision display screen via signal lines, and the decision display screen is connected to the vehicle computer via a signal line.

[0018] Preferably, the data analyzer is used to receive detection data from two laser rangefinders and two millimeter-wave radars; the image analyzer is used to detect and analyze vehicles on the road directly in front of the vehicle and on both sides, determine the vehicle type, determine the driving trajectory of the vehicles in front, and communicate with the vehicles in front through the V2X communication module to obtain the driving data of the vehicles in front; the decision display screen has a built-in logic analysis module for logical analysis and decision-making on whether the vehicle needs to decelerate, and feeds back the analysis and decision results to the vehicle computer.

[0019] The beneficial effects of this invention are as follows: By integrating laser rangefinders and millimeter-wave radar into the rearview mirror assembly of an intelligent driving vehicle, while keeping the positions of the laser radar, millimeter-wave radar, and infrared sensors on the vehicle body unchanged, during intelligent driving, the two laser rangefinders and two millimeter-wave radars detect the distance to the vehicle ahead. Simultaneously, they analyze images captured by the dashcam to determine the vehicle's trajectory and type. Using a V2X communication module, they communicate with the vehicle ahead and base stations to acquire its driving data. Based on this information, they make independent judgments and feed the judgments and decisions back to the vehicle's computer. This allows for timely judgment and braking to prevent collisions, improving safety and reducing the load on the vehicle's computer. Attached Figure Description
