[0040] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0043] It should be understood that although the terms first, second, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, a first vehicle may also be referred to as a second vehicle, and similarly, a second vehicle may also be referred to as a first vehicle. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0044] Please refer to Figure 1 This diagram illustrates an implementation environment for a vehicle state control method provided in an exemplary embodiment of this application. Figure 1 As shown, the implementation environment may include: a first vehicle 110 and at least one second vehicle 120, wherein the distance between the second vehicle 120 and the first vehicle 110 does not exceed a specified threshold (e.g., one kilometer). The second vehicle 120 includes the vehicle in front of the first vehicle 110 and the vehicle behind the first vehicle 110.

[0045] The first vehicle 110 includes a data acquisition unit 110a, a direct communication unit 110b, and a decision control unit 110c, while the second vehicle 120 includes a data acquisition unit 120a, a direct communication unit 120b, and a decision control unit 120c.

[0046] The aforementioned data acquisition units 110a and 120a are used to collect vehicle status information of the first vehicle 110 and the second vehicle 120, and may include speed sensors, onboard positioning and navigation antennas, lane-level navigation systems, inertial measurement units (IMUs), advanced driver assistance system (ADAS) sensors, etc. The speed sensors are mounted on the wheels or transmission, measuring the wheel rotation speed and converting it into the driving speed of the first vehicle 110 and the second vehicle 120. The onboard positioning and navigation antenna is mounted on the roof of the vehicle, receiving signals from satellites or base stations to obtain the real-time location information of the first vehicle 110 and the second vehicle 120. The lane-level navigation system combines high-precision maps and GPS signals, using cameras to identify lane lines or utilizing radar and LiDAR for environmental perception, thereby determining the lanes where the first vehicle 110 and the second vehicle 120 are located. The Inertial Measurement Unit (IMU) integrates accelerometers and gyroscopes, providing information such as acceleration and angular velocity for the first vehicle 110 and the second vehicle 120. Through algorithmic fusion, the attitude and heading of the first vehicle 110 and the second vehicle 120 can be estimated. Advanced Driver Assistance System (ADAS) sensors include cameras, radar, and lidar. These sensors are not only used for environmental perception but also, through algorithmic processing, can assist in determining the driving position and heading angle of the first vehicle 110 and the second vehicle 120.

[0047] The aforementioned direct communication units 110b and 120b are wireless communication devices used to transmit and receive vehicle-to-vehicle (V2V) communication information, such as warning information and vehicle status information, with adjacent vehicles or infrastructure. For example, the aforementioned direct communication units 110b and 120b are responsible for transmitting in real time vehicle status information (such as speed, acceleration, position, and heading angle) of vehicles within a one-kilometer range, enabling wireless information sharing between the first vehicle 110 and the second vehicle 120.

[0048] The aforementioned decision control units 110c and 120c are used to adjust the vehicle's status, such as speed and path, based on the vehicle's own status information and the status information of adjacent vehicles. For example, decision control units 110c and 120c may include a data fusion and analysis module and an execution and control module. The data fusion and analysis module integrates high-precision combined navigation sensor data and vehicle-to-everything (V2X) communication information. Using the vehicle analysis module's data analysis technology, it accurately identifies potential rear-end collision risks and congestion signs, predicts vehicle behavior trends, and generates warning signals and intervention suggestions. Upon receiving instructions from the decision control module, the execution and control module implements active driving interventions, such as adjusting speed or changing lanes, through the vehicle's execution system (advanced driver assistance system) or directly by acting on the vehicle control unit.

[0049] For example, when the first vehicle 110 is in motion, the data acquisition unit 110a of the first vehicle 110 acquires the vehicle status information of the first vehicle 110 and sends it to the decision control unit 110c; the vehicle status information is used to indicate the vehicle's driving data. The first vehicle can receive the vehicle status information of the second vehicle 120 sent by the second vehicle 120 through the direct communication unit 120b; the second vehicle 120 is a vehicle located within a specified range in front of the first vehicle 110; the vehicle status information of the second vehicle 120 is acquired by the data acquisition unit 120a of the second vehicle 120 and sent to the direct communication unit 120b. When the decision control unit 110c determines that the vehicle status information of the first vehicle 110 and the vehicle status information of the second vehicle 120 meet a first condition, the decision control unit 110c of the first vehicle 110 can play a voice reminder message; the voice reminder message is used to indicate the driving status of the second vehicle 120. When the decision control unit 110c determines that the vehicle status information of the first vehicle 110 and the vehicle status information of the second vehicle 120 meet the second condition, the decision control unit 110c of the first vehicle 110 can adjust the driving state of the first vehicle 110.

[0050] Please refer to Figure 2 The diagram illustrates a flowchart of a vehicle state control method provided in an exemplary embodiment of this application. The method is executed by a first vehicle. Optionally, the vehicle may be... Figure 1 The first vehicle 110 in the system shown. (e.g.) Figure 2 As shown, the method may include steps 210, 220, 230 and 240.

[0051] Step 210: When the first vehicle is in motion, obtain the vehicle status information of the first vehicle; the vehicle status information is used to indicate the vehicle's driving data.

[0052] In this embodiment of the application, when the first vehicle is in a driving state, the data acquisition unit of the first vehicle can collect the vehicle status information of the first vehicle and send the collected vehicle status information to the decision control unit.

[0053] Optionally, the first vehicle can send its vehicle status information to the second and third vehicles. For example, the data acquisition unit of the first vehicle can also send the acquired vehicle status information to the direct communication unit of the first vehicle, which then sends the vehicle status information to the direct communication units of the second and third vehicles. Correspondingly, the direct communication units of the second and third vehicles can send the vehicle status information to the decision control units of the second and third vehicles, respectively.

[0054] The aforementioned vehicle status information includes at least one of the following:

[0055] 1) Vehicle speed: This refers to the distance a vehicle travels per unit time, describing how fast or slow the vehicle moves. It can be measured by speed sensors installed on the wheels or transmission system. For example, optical speed sensors detect the pulse signals generated when the wheels rotate and block light, and calculate the vehicle speed based on the relationship between the wheel circumference and the pulse frequency. Another example is electromagnetic speed sensors, which use the principle of electromagnetic induction to calculate the speed based on the induced electromotive force generated by the change in the magnetic field when the wheels rotate.

[0056] 2) Vehicle acceleration: This refers to the rate of change of vehicle speed, which is the derivative of speed with respect to time. It reflects the dynamic characteristics of the vehicle during acceleration or deceleration and can be measured by an acceleration sensor. For example, in a microelectromechanical system (MEMS) acceleration sensor, when the vehicle accelerates or decelerates, a tiny mass block inside the sensor will generate a corresponding displacement. This displacement is converted into an electrical signal, which, after processing, yields the vehicle's acceleration value.

[0057] 3) Vehicle Position: This refers to the vehicle's specific geographical location within the road network and its lane information. Accurate position information is crucial for navigation, traffic management, and safe driving. The Global Positioning System (GPS) is the primary means of obtaining a vehicle's position, determining its latitude and longitude coordinates by receiving satellite signals, thus determining its approximate location on Earth. However, GPS alone is insufficient for lane-level precision. To more accurately determine a vehicle's lane, other technologies are typically combined. For example, vision-based lane recognition technology uses cameras mounted on vehicles to capture road images, and image recognition algorithms analyze lane line shape, color, and position information to determine the vehicle's position within the lane. Another approach is based on high-precision maps and sensor fusion. High-precision maps contain detailed road information, such as lane width, curvature, and slope, which, combined with real-time sensing data from sensors like radar and lidar, can more accurately determine a vehicle's position (lane).

[0058] 4) Vehicle heading angle: This refers to the angle between the vehicle's longitudinal axis (direction of travel) and a reference direction (usually true north), describing the vehicle's direction of travel. For example, the heading angle can be measured using an electronic compass. The electronic compass utilizes the characteristics of the Earth's magnetic field, detecting the direction of the magnetic field through a magnetic sensor to determine the vehicle's heading angle relative to magnetic north. Alternatively, the heading angle can be obtained by calculating the vehicle's trajectory direction using the Global Positioning System (GPS) and continuously recording the vehicle's position coordinates at different times. Another example is the measurement of the vehicle's angular velocity using a gyroscope in an inertial measurement unit (IMU). Integrating the angular velocity can also yield the change in heading, thus determining the heading angle.

[0059] Step 220: Receive vehicle status information of the second vehicle sent by the second vehicle; the second vehicle is a vehicle located within a specified range in front of the first vehicle.

[0060] In this context, the second vehicle is the vehicle preceding the first vehicle. Optionally, the second vehicle could be... Figure 1 The system shown includes a second vehicle 120. For example, the specified range could be one kilometer or another range, which is not limited in this application. That is, the second vehicle is a vehicle located within one kilometer in front of the first vehicle.

[0061] For example, the data acquisition unit of the second vehicle can collect the vehicle status information of the second vehicle and send the collected vehicle status information to the direct communication unit of the second vehicle. That is, the second vehicle can obtain the vehicle status information of the second vehicle through the data acquisition unit of the second vehicle and send the vehicle status information of the second vehicle to the direct communication unit of the first vehicle; correspondingly, the direct communication unit of the first vehicle can receive the vehicle status information of the second vehicle and send the vehicle status information of the second vehicle to the decision control unit of the first vehicle.

[0062] In this embodiment, the first vehicle and the second vehicle communicate directly within the same area. This shortens the data transmission path, eliminates the need to send data to the cloud (which processes it before sending), and enables rapid response and real-time control. This is suitable for applications with extremely high real-time requirements. For example, if both vehicles are traveling on a highway, and the second vehicle ahead of the first vehicle suddenly slows down, the first vehicle can quickly detect this change and adjust its speed and lane accordingly, ensuring driving safety and improving traffic efficiency.

[0063] Step 230: If the vehicle status information of the first vehicle and the vehicle status information of the second vehicle meet the first condition, play a voice reminder message; the voice reminder message is used to indicate the driving status of the second vehicle.

[0064] In this embodiment of the application, after the first vehicle obtains its own vehicle status information and receives the vehicle status information of the second vehicle, it can determine through the decision control unit whether the vehicle status information of the first vehicle and the vehicle status information of the second vehicle meet the first condition.

[0065] The first condition mentioned above is a pre-stored condition in the first vehicle used to determine whether a voice reminder message needs to be played. For example, the first condition can be satisfied when the vehicle status information of the first vehicle and the vehicle status information of the second vehicle are both less than a specified speed (e.g., 30 km / h) and the distance between the first vehicle and the second vehicle is less than a specified length (e.g., 200 meters).

[0066] Optionally, during the process of playing the voice reminder message, the first vehicle may play the voice reminder message in the following manner:

[0067] Pre-recorded voice prompts: The first vehicle can play pre-recorded voice prompts, such as "There is a vehicle ahead, please slow down" or "Vehicle ahead slows down, please keep a safe distance." These voice prompts are stored in the system's storage medium. When the vehicle status information of the first vehicle and the vehicle status information of the second vehicle meet the first condition, the decision control unit of the first vehicle will call and play them.

[0068] Text-to-speech technology: For more flexible needs, text-to-speech technology can be used to generate instant voice reminders. This method allows for the dynamic generation of different warning messages based on specific circumstances, thereby providing a more personalized reminder service.

[0069] It should be noted that after the first vehicle plays the voice reminder message, the driver of the first vehicle can actively respond to the content of the voice reminder message, such as taking measures such as slowing down to maintain a safe distance.

[0070] Step 240: If the vehicle status information of the first vehicle and the vehicle status information of the second vehicle meet the second condition, adjust the driving status of the first vehicle.

[0071] In this embodiment of the application, after the first vehicle obtains its own vehicle status information and receives the vehicle status information of the second vehicle, it can determine through the decision control unit whether the vehicle status information of the first vehicle and the vehicle status information of the second vehicle meet a second condition. If the vehicle status information of the first vehicle and the vehicle status information of the second vehicle meet the second condition, it means that a rear-end collision is about to occur or there is lane congestion ahead.

[0072] The second condition mentioned above is a pre-stored condition in the first vehicle used to determine whether the driving state of the first vehicle needs to be adjusted. For example, the second condition can be satisfied if the vehicle state information of the first vehicle and the vehicle state information of the second vehicle are both greater than a specified speed (e.g., 80 km / h) and the distance between the first vehicle and the second vehicle is less than a specified length (e.g., 100 meters).

[0073] Optionally, adjusting the driving state of the first vehicle includes at least one of the following: adjusting the driving speed of the first vehicle, adjusting the driving lane of the first vehicle, and adjusting the driving direction of the first vehicle. For example, the first vehicle can perform safe emergency slow braking.

[0074] Optionally, during the process of adjusting the driving status of the first vehicle, the first vehicle may activate its hazard lights to alert vehicles behind it to the current status of the first vehicle.

[0075] In summary, the solution presented in this application embodiment allows a second vehicle located in front of the first vehicle to send its vehicle status information (such as speed and location) to the first vehicle via direct vehicle-to-vehicle communication when the first vehicle is in motion (e.g., at high speed). The first vehicle can then combine its own vehicle status information with that of the second vehicle to issue a warning to its user or adjust its own vehicle status (e.g., speed, lane). This solution employs a direct intra-regional communication method with a short data transmission path, achieving not only simple and efficient timeliness and accuracy of warnings but also dynamic adjustment of vehicle driving strategies based on real-time conditions. This effectively avoids potential dangers, reduces driver stress, and ultimately ensures driving safety and improves traffic efficiency.

[0076] Based on the above Figure 2 In one possible implementation of the scheme shown in the embodiment, step 240 can be implemented as follows:

[0077] Step 240a: If the vehicle status information of the first vehicle and the vehicle status information of the second vehicle meet the second condition, reduce the driving speed of the first vehicle; the second condition includes the driving speed of the first vehicle being greater than the first specified speed and the distance between the first vehicle and the second vehicle being less than the first specified length.

[0078] In other words, when a rear-end collision is imminent or there is lane congestion ahead, the first vehicle can reduce its speed to avoid a collision or other accidents, thereby ensuring driving safety and improving traffic efficiency.

[0079] In this embodiment, during the process of reducing the speed of the first vehicle, the first vehicle can reduce its speed through the braking system. The braking system refers to a series of specialized devices that apply a certain force to the wheels of the vehicle, thereby forcibly braking the vehicle to a certain extent. The braking system consists of components such as a brake pedal, master cylinder, wheel cylinders, brake pads, and brake discs (drums).

[0080] For example, if the vehicle status information of the first vehicle and the vehicle status information of the second vehicle meet the second condition, the decision control unit of the first vehicle can send a braking command to the braking system of the first vehicle. The braking command is used to instruct the first vehicle to reduce its driving speed.

[0081] The first specified speed and the first specified length are pre-stored in the first vehicle and are critical conditions used to determine whether the speed of the first vehicle needs to be reduced. For example, the first specified speed can be 80 km / h and the first specified length can be 100 meters. The first specified speed and the first specified length can also be other pre-set values, and this application does not limit them.

[0082] Based on the solutions shown in the above embodiments of this application, in one possible implementation, the vehicle state control method further includes steps 250 and 260.

[0083] Step 250: Receive vehicle status information sent by the third vehicle; the third vehicle is a vehicle located within a specified range behind the first vehicle.

[0084] The third vehicle mentioned above is the vehicle following the first vehicle. Optionally, the third vehicle can be... Figure 1 The second vehicle 120 in the system shown. For example, the specified range could be one kilometer or another range, which is not limited in this application. That is, the third vehicle is a vehicle located within one kilometer behind the first vehicle.

[0085] For example, the data acquisition unit of the third vehicle can collect the vehicle status information of the third vehicle and send the collected vehicle status information to the direct communication unit of the third vehicle. That is, the third vehicle can obtain the vehicle status information of the third vehicle through the data acquisition unit of the third vehicle and send the vehicle status information of the third vehicle to the direct communication unit of the first vehicle; correspondingly, the direct communication unit of the first vehicle can receive the vehicle status information of the third vehicle and send the vehicle status information of the third vehicle to the decision control unit of the first vehicle.

[0086] In this embodiment, the first vehicle and the third vehicle use a direct intra-regional communication method, which has a short data transmission path and does not need to be sent to the cloud. Instead, the data is processed by the cloud and then sent, which can achieve the effect of fast response and real-time control. This method is suitable for application scenarios with extremely high real-time requirements.

[0087] Step 260: If the vehicle status information of the second vehicle and the vehicle status information of the third vehicle meet the third condition, change the driving lane of the first vehicle from the first lane to the second lane; the third condition includes that the heading angle of the second vehicle in the first lane is less than the first specified angle, the heading angle of the third vehicle in the first lane is less than the second specified angle, the driving speed of the third vehicle in the second lane is less than the second specified speed and the distance between the third vehicle and the first vehicle is greater than the second specified length.

[0088] In this embodiment of the application, after receiving the vehicle status information of the second vehicle and the vehicle status information of the third vehicle, the first vehicle can determine whether the vehicle status information of the second vehicle and the vehicle status information of the third vehicle meet the third condition through the decision control unit.

[0089] The third condition mentioned above is a pre-stored condition in the first vehicle, used to determine whether the first vehicle's driving lane needs to be changed from the first lane to the second lane. For example, the first specified angle can be 3°, the second specified angle can be 3°, the second specified speed can be 80km / h, and the second specified length can be 100 meters. The first specified angle, the second specified angle, the second specified speed, and the second specified length can also be other pre-set values, which are not limited in this application.

[0090] This application embodiment illustrates a feasible solution for determining whether the driving lane of the first vehicle can be changed based on the vehicle status information of the second vehicle in front of the first vehicle and the vehicle status information of the third vehicle behind the first vehicle. When the vehicle status information of the second vehicle and the vehicle status information of the third vehicle meet the lane-changing conditions, the first vehicle changes its driving lane from the first lane to the second lane, ensuring driving safety and improving traffic efficiency.

[0091] Based on the solutions shown in the above embodiments of this application, in one possible implementation, the vehicle state control method further includes:

[0092] During the process of adjusting the driving status of the first vehicle, a prompt message is sent to the third vehicle; the prompt message is used to indicate the changes in the driving status of the first vehicle.

[0093] In other words, when the first vehicle adjusts its driving status, it can promptly send the changes to the third vehicle behind it. This allows the third vehicle to quickly receive information about the changes and adjust its own driving status accordingly, ensuring driving safety. For example, if the first vehicle slows down, the third vehicle, which is relatively close to it, can slow down in time to avoid a rear-end collision.

[0094] For example, the changes in the driving state of the first vehicle include at least one of the following: changes in the driving speed of the first vehicle, changes in the driving acceleration of the first vehicle, changes in the heading angle of the first vehicle, and changes in the driving lane of the first vehicle.

[0095] Optionally, the first vehicle can transmit changes in its driving status to the direct communication unit of the third vehicle via its direct communication unit. Correspondingly, after receiving the changes in the first vehicle's driving status, the third vehicle's direct communication unit transmits these changes to the third vehicle's decision control unit. Then, the third vehicle's decision control unit determines whether to adjust the third vehicle's driving status based on the changes in the first vehicle's driving status and the third vehicle's vehicle status information.

[0096] Based on the solutions shown in the above embodiments of this application, in one possible implementation, the vehicle state control method further includes:

[0097] Upon receiving a user control command, the adjustment of the driving state of the first vehicle is stopped; the user control command includes at least one of the following: the brake pedal is depressed, the brake pedal is depressed for a duration longer than a specified duration, the warning lights of the first vehicle are turned off, and the emergency braking state is released.

[0098] In other words, when a human takes over the first vehicle, the decision control unit of the first vehicle relinquishes automatic control of the first vehicle and returns control to the user to avoid conflicts between automatic control and user control and to ensure the safety of vehicle operation.

[0099] The aforementioned "brake pedal being pressed" refers to the user pressing the brake pedal. For example, the first vehicle can determine whether the brake pedal is pressed by the sensor signal of the brake pedal. The aforementioned "brake pedal being pressed for a duration longer than a specified duration" refers to the user continuously pressing the brake pedal. For example, the specified duration could be 2 seconds, or other values; this application does not limit this.

[0100] The aforementioned warning lights being turned off in the first vehicle refers to the user manually turning off the warning lights (such as hazard lights). The aforementioned emergency braking being released refers to the user manually releasing the emergency braking.

[0101] This application also provides a vehicle control system, which includes a data acquisition unit, a direct communication unit, and a decision control unit;

[0102] The data acquisition unit is used to acquire the vehicle status information of the first vehicle when the first vehicle is in motion; the vehicle status information is used to indicate the vehicle's driving data.

[0103] The direct communication unit is used to receive vehicle status information of the second vehicle sent by the second vehicle; the second vehicle is a vehicle located within a specified range in front of the first vehicle.

[0104] The decision control unit is used to play a voice reminder message when the vehicle status information of the first vehicle and the vehicle status information of the second vehicle meet a first condition; the voice reminder message is used to indicate the driving status of the second vehicle.

[0105] The decision control unit is used to adjust the driving state of the first vehicle when the vehicle status information of the first vehicle and the vehicle status information of the second vehicle meet the second condition.

[0106] The specific methods by which the vehicle control system, engine control unit, and transmission control unit perform operations in the above embodiments have been described in detail in the embodiments related to the method, and will not be elaborated here.

[0107] The vehicle state control method shown in the above embodiments of this application can be applied to a control method for a simple, small-scale, efficient, high-speed vehicle rear-end collision and road congestion early warning and intervention system.

[0108] In modern transportation systems, with the surge in vehicle numbers and deepening urbanization, road safety issues have become increasingly serious. Rear-end collisions on highways and secondary disasters caused by lane congestion have become problems that cannot be ignored. Statistics show that rear-end collisions and traffic congestion are among the main causes of decreased traffic efficiency and damage to public life and property. Especially at high speeds, drivers have less reaction time to road conditions ahead, and the kinetic energy of vehicles traveling at high speeds is enormous. Once a rear-end collision occurs, it often results in serious casualties and economic losses.

[0109] Current intelligent transportation systems and vehicle safety technologies, such as ADAS, adaptive cruise control, autonomous driving, and vehicle-road-cloud collaborative perception, can improve driving safety and road efficiency. However, these systems mainly rely on the detection range of the vehicle's own sensors. Vehicle-road-cloud collaborative systems are complex and costly. Their response rate and early warning for long-distance traffic events and unpredictable emergencies (such as sudden braking, accidents ahead, road closures, etc.) cannot be widely applied in the short term. They also cannot effectively prevent high-speed rear-end collisions and alleviate safety hazards caused by congestion in the short term.

[0110] To address the aforementioned issues, this control method eliminates the need for a cloud-based system, employing direct intra-regional communication to achieve real-time monitoring, accurate prediction, and proactive intervention of high-speed vehicle rear-end collision risks and lane congestion. Through inter-vehicle wireless communication and positioning systems, vehicle status information (speed, acceleration, position, heading angle, etc.) can be shared in real time. This not only provides simple and efficient timeliness and accuracy in early warning but also allows for dynamic adjustments to vehicle driving strategies based on real-time conditions, effectively avoiding potential dangers and reducing driver stress. Therefore, it provides strong technical support for building a safe, efficient, and green intelligent transportation system.

[0111] like Figure 3As shown, a simple, small-scale, and efficient high-speed vehicle rear-end collision and lane congestion early warning and intervention system includes an onboard positioning and navigation antenna 1, a decision control unit 2, and a one-kilometer wireless communication device 3. The onboard positioning and navigation antenna 1 is used to acquire the real-time location information of the vehicle. The decision control unit 2 is responsible for processing and analyzing the information acquired from the onboard positioning and navigation antenna and making decisions based on a preset algorithm. The wireless communication device 3 is used to communicate with adjacent vehicles or infrastructure to transmit and receive early warning information.

[0112] The aforementioned one-kilometer wireless communication device 3 is a wireless transceiver in the vehicle-to-vehicle (V2V) communication module, responsible for transmitting real-time vehicle status (speed, acceleration, position, heading angle) information within a one-kilometer range, enabling wireless information sharing between vehicles.

[0113] The aforementioned decision control unit 2 includes a data fusion and analysis module and an execution and control module. The data fusion and analysis module integrates high-precision combined navigation sensor data and V2X communication information. Utilizing data analysis technology from the vehicle analysis module, it accurately identifies potential rear-end collision risks and congestion signs, predicts vehicle behavior trends, and generates warning signals and intervention suggestions. Upon receiving instructions from the decision module, the execution and control module implements active driving interventions, such as adjusting vehicle speed and changing lanes, either through the vehicle's execution system (advanced driver assistance system) or directly on the vehicle control unit.

[0114] like Figure 4 As shown, the specific steps of a simple, small-scale, and efficient control method for a high-speed vehicle rear-end collision and lane congestion early warning and intervention system are as follows:

[0115] Step 1, obtain vehicle information within the range:

[0116] The vehicle-mounted positioning and navigation antenna 1 acquires the vehicle's real-time location information. After the vehicle starts moving, it can acquire the corresponding vehicle's heading angle. The decision control unit 2 receives information such as the position, heading angle, and acceleration of adjacent vehicles through a one-kilometer wireless communication device 3.

[0117] Step 2: Analyze vehicle information and make decisions:

[0118] The decision control unit 2 analyzes the acquired vehicle information, including but not limited to location, speed, and direction. Based on preset algorithms or rules, it determines whether there is a risk of rear-end collision or lane congestion.

[0119] Step 3: Decide whether to provide a voice prompt based on the decision:

[0120] If a risk is detected, the decision control unit 2 will trigger a voice alert to remind the driver to pay attention to the situation ahead. If there is no risk, no voice alert will be given.

[0121] Step 4: If danger is detected, apply emergency braking:

[0122] If the system detects an impending rear-end collision or lane congestion, the decision control unit 2 will immediately activate the emergency braking function to avoid a collision.

[0123] Step 5, manually intervene by pressing the accelerator pedal:

[0124] After emergency braking, if the driver presses the accelerator pedal, the system will release the emergency braking state and restore normal driving control.

[0125] Step 6, restore normal control:

[0126] Once the system confirms that the danger has been eliminated and the vehicle has returned to normal driving status, the decision control unit 2 will resume normal control mode.

[0127] In summary, this solution significantly improves driving safety in high-speed environments. Through real-time monitoring and intelligent analysis of vehicle status information within a one-kilometer radius, the system can anticipate potential rear-end collision risks and traffic congestion, promptly issuing warning signals to drivers. Furthermore, the system can proactively adjust vehicle driving strategies, such as immediate deceleration, suggesting lane changes, or taking emergency evasive action, effectively preventing high-speed rear-end collisions, significantly reducing traffic fatalities, and providing a safer driving environment for drivers and passengers.

[0128] The implementation of this technical solution significantly reduces costs, allows for rapid vehicle installation and application in a short period, and alleviates the psychological and physiological burden on drivers. Intelligent warning and intervention functions reduce the driver's pressure in judging complex road conditions, enabling them to focus on driving, reducing driver fatigue, simplifying driving operations, making the driving process easier, and improving the driving experience and comfort.
