Lateral collision early warning control method and system

Abstract

The invention provides a lateral collision early warning control method and system. The method comprises the following steps: collecting image data around a vehicle body; judging whether the data of the vehicle side backward camera fails or not; if yes, whether data of the electronic rearview mirror camera fails or not is judged; if the data of the electronic rearview mirror camera fails, the character prompt early warning function fails, and the image data of the electronic streaming media outside rearview mirror is displayed; and if the data of the electronic rearview mirror camera has no fault, using electronic streaming media outside rearview mirror image data to display images around a vehicle body and continuously early warning. The traffic condition around the vehicle, especially the blind area on the side face of the vehicle, is detected in real time through sensors such as the left and right rear cameras and the left and right electronic rearview mirror cameras, so that once the left and right rear cameras fail, the system can immediately switch and use data of the left and right electronic rearview mirror cameras; the redundant function can greatly improve the driving safety of the driver and reduce the occurrence of lateral collision accidents.

Description

Technical Field

[0001] The present invention relates to the technical field of vehicle collision warning, and in particular to a lateral collision warning control method and system. Background Art

[0002] Side collision warning is a car safety technology designed to detect and warn the driver of the risk of a possible side collision while the vehicle is in motion. Side collision warning systems can greatly improve the driver's driving safety, especially in complex environments such as highways, mountain roads, and busy urban roads. This system usually uses sensors such as cameras to monitor the environment around the vehicle, especially the blind spots on the side of the vehicle. When the system detects a potential risk of a side collision, it will warn the driver so that the driver can take evasive measures in time to avoid an accident.

[0003] In the prior art, the side collision warning function generally relies only on the side camera, which makes the side collision warning function in the prior art often lack redundancy, that is, the lack of a backup camera means that if the main camera fails or is damaged, the side collision warning function will be completely ineffective. Such a system lacks redundancy, which increases the vulnerability of the overall system. Summary of the invention

[0004] Based on this, the purpose of the present invention is to provide a lateral collision warning control method and system, which is used to solve the technical problem that the lateral collision warning function in the prior art generally relies only on side cameras, resulting in a lack of redundancy in the system and increasing the vulnerability of the overall system.

[0005] In one aspect, the present invention provides a side collision warning control system, comprising an ADCU controller, and two electronic rearview mirror cameras, two vehicle side rear-facing cameras and an electronic streaming media exterior rearview mirror respectively connected to the ADCU controller, wherein:

[0006] The ADCU controller is a core component of the autonomous driving system. It receives data from various sensors and performs real-time processing and analysis to control the vehicle's motion status, environmental perception, and decision-making planning. The ADCU controller is also responsible for communicating and coordinating with other vehicle systems and components, including electronic control units and actuators.

[0007] Electronic rearview mirror camera, used to replace traditional optical rearview mirrors, captures images behind the vehicle through the camera and transmits real-time video stream to the display screen inside the vehicle, providing the driver with a view of the rear of the vehicle;

[0008] The vehicle side rear-facing camera is installed on the side or rear of the vehicle to capture the traffic situation behind the vehicle and provide the driver with a side view to provide side information, including the safety information required when the vehicle changes lanes, reverses or parks;

[0009] The electronic streaming media exterior rearview mirror combines an electronic rearview mirror camera and streaming media technology to display the real-time images captured by the camera to the driver through the in-car display screen.

[0010] In addition, the side collision warning control system according to the present invention may also have the following additional technical features:

[0011] Furthermore, the frame rate of the electronic rearview mirror camera is consistent with that of the vehicle's side rear-facing camera.

[0012] Furthermore, the frame rate of the electronic rearview mirror camera and the vehicle side rear-facing camera is not less than 60 Hz.

[0013] Another aspect of the present invention provides a lateral collision warning control method, which is applied to the above-mentioned lateral collision warning control system. The method specifically acts on an ADCU controller, and the method includes:

[0014] Collect image data around the vehicle body;

[0015] Determining whether the data of the vehicle side rear-facing camera is faulty based on the image data around the vehicle body;

[0016] If the data of the vehicle's side rear-view camera fails, determine whether the data of the electronic rearview mirror camera fails;

[0017] If the data of the electronic rearview mirror camera fails, the text prompt warning function fails and the image data of the electronic streaming media exterior rearview mirror is displayed;

[0018] If there is no fault in the data from the electronic rearview mirror camera, the electronic streaming media exterior rearview mirror image data will be used to display the image around the vehicle body and provide continuous warning.

[0019] In addition, the side collision warning control method according to the present invention may also have the following additional technical features:

[0020] Furthermore, after the step of determining whether the data of the vehicle side rear-facing camera is faulty according to the vehicle body surrounding image data, the method further includes:

[0021] If there is no fault in the data from the vehicle's side rear-facing camera, the side rear-facing image data will be used to display the image around the vehicle body and provide continuous warning.

[0022] The above-mentioned side collision warning control method and system detect the traffic conditions around the vehicle in real time through sensors such as left and right side rear cameras and left and right electronic rearview mirror cameras, especially the blind spots on the sides of the vehicle. Once a failure of the left or right side rear cameras is detected, the system will immediately switch to using the data of the left and right electronic rearview mirror cameras. This redundant function can greatly improve the driver's driving safety and reduce the occurrence of side collision accidents. BRIEF DESCRIPTION OF THE DRAWINGS
