[0002] For intelligent parking spaces, in parking areas with dense crowds such as hospitals and commercial comprehensive buildings, currently, vehicle owners still need to look for parking spaces. This often easily leads to missing available parking spaces after driving around the parking lot, and then having to return to the starting point of entering the parking lot and start looking again. Summary of the Invention

[0006] An information collection step, obtaining parking space information in the parking lot and vehicle information at the entrance of the parking lot, and applying to connect to the vehicle interaction module. If the vehicle allows interaction, it is connected through the interaction module; if the vehicle does not allow interaction, signal transmission is carried out through the guidance screen in the parking lot;

[0007] A parking space matching step, according to the vehicle information and the parking space information, obtaining corresponding parking information through a path planning strategy, where the parking information includes the parking position and the optimal parking route;

[0008] An interaction guidance step, when the vehicle allows interaction, the vehicle is used to receive the parking information;

[0009] A traditional guidance step, when the vehicle does not allow interaction, it is used to obtain the position of the vehicle in the parking lot, judge the vehicle's traveling path, obtain the nearest guidance screen on the vehicle's traveling path, and indicate the vehicle's direction and recommend parking space information on the guidance screen.

[0010] Preferably, the path planning strategy includes an automatic avoidance step. When a new vehicle enters the parking lot, it is used to obtain the path information of all running vehicles in the parking lot, generate a vehicle running trajectory map, synchronously predict the paths of all vehicles within the same time, use the lane intersection points as nodes to judge whether the vehicles meet at the nodes, then generate a new path, and synchronously predict whether congestion will occur. If congestion is likely to occur, it is recommended that the new vehicle adjust its speed to avoid congestion.

[0011] Preferably, the path planning strategy further includes an optimization step for obtaining vehicle requirements. According to the vehicle requirements, the best parking position is selected, and vehicle requirements are obtained. The vehicle requirements include the remaining power of the vehicle and the estimated staying time. According to the remaining power of the vehicle and the estimated staying time, the vehicles are ranked by priority, and vehicles with lower remaining power or shorter estimated staying time are given priority to enter the fast charging parking spaces.

[0012] Preferably, the traditional guiding step further includes an intelligent following vehicle strategy, which includes

[0013] A vehicle identification step for obtaining information on all vehicles in the parking lot that require traditional guidance and their driving paths, and judging whether there is partial overlap in the driving time and vehicle paths. If there is overlap, a following vehicle instruction is issued, and the leading vehicle information is determined according to the vehicle position;

[0014] A following vehicle guiding step. During the path overlap stage, the guiding sign indicates the driving direction of the vehicle, and the indicator light is always on;

[0024] Advantages of the present invention: It displays the parking space distribution pattern and the position map of the parking space number display board, solving the problem that after the vehicle enters the parking lot, the vehicle owner does not know where there are vacant parking spaces available and needs to spend a long time looking for vacant parking spaces. Most parking lots have many management personnel for command, which can reduce the number of personnel; when the vehicle enters the entrance of the passage, the electronic display screen at the entrance shows the address number of the parking space where the vehicle owner needs to park, and there are lighting indicators for the driving route, avoiding the need to set many management personnel to guide on each floor, greatly wasting manpower and the vehicle owner's time to find a parking space.

[0030] The following further details the embodiments of the present invention with reference to the accompanying drawings:

[0031] A digital intelligent parking space intelligent parking guidance method,

[0032] Information collection step: Obtain the parking space information in the parking lot and the vehicle information at the entrance of the parking lot, and apply to connect to the vehicle interaction module. If the vehicle allows interaction, connect through the interaction module; if the vehicle does not allow interaction, transmit signals through the guidance screens in the parking lot. In the information collection stage, the parking space information in the parking lot is collected through the cooperation of multiple sensors. The geomagnetic sensors are buried under each parking space and can accurately sense whether the parking space is occupied. By sensing the geomagnetic changes caused by the parked vehicle, the parking space status data is transmitted to the parking lot management system in real time. At the same time, at the entrance of the parking lot, high-definition cameras are set up. Using advanced image recognition technology, the vehicle license plate information is quickly recognized, and data such as vehicle type (such as small cars, SUVs, commercial vehicles, etc.) and body size are obtained. For the connection application of the vehicle interaction module, the parking lot management system will send an encrypted connection request to the in-vehicle intelligent terminal of the vehicle. If the vehicle allows interaction, a stable connection is established between the two parties through Bluetooth or vehicle networking technology to ensure the secure transmission of information. If the vehicle does not allow interaction, the system automatically records the vehicle information and prepares for signal transmission through the guidance screen control module pre-laid in the parking lot. The guidance screen control module is connected to each guidance screen through a wired or wireless network to ensure the stability of information transmission.

[0033] Parking space matching step: Based on vehicle information and parking space information, through a path planning strategy, corresponding parking information is obtained. The parking information includes the parking location and the optimal parking route. According to the collected vehicle information and real-time parking space information, the path planning strategy uses a complex algorithm model. First, considering the vehicle type and size, parking spaces that meet the vehicle parking conditions are screened. For small cars, standard-sized parking spaces can be selected; while for large SUVs or commercial vehicles, larger-sized dedicated parking spaces are preferentially matched. Then, combined with the real-time traffic conditions in the parking lot, by analyzing the vehicle flow speed and congestion situation in each area, the shortest path or optimal path from the current vehicle position (i.e., the parking lot entrance) to each optional parking space is calculated. The evaluation criteria for the optimal path comprehensively consider factors such as distance, number of turns, and whether passing through busy areas. Finally, parking information including the parking location and the detailed optimal parking route is generated; the parking route is presented in the form of a sequence of coordinate points, and the driving direction and distance between each point are marked.

[0034] Interactive guidance step: When the vehicle allows interaction, the vehicle is used to receive parking information; when the vehicle allows interaction and the in-vehicle intelligent terminal receives the parking information, the optimal parking route is displayed in an intuitive map navigation form through the vehicle's central control display screen. The route is marked with a prominent color line on the parking lot map, and at the same time, the remaining distance and direction prompt to the next turning point or key position are displayed in real time on the screen. In addition, the in-vehicle intelligent terminal can also provide real-time voice navigation for the driver through the voice broadcast function, clearly informing the driver when to turn and when to go straight, etc., greatly improving the convenience and accuracy of the driver to find a parking space. At the same time, the system will update the navigation information in real time according to the driving situation of the vehicle. If the vehicle deviates from the optimal route, the route will be re-planned in time and the driver will be reminded.

[0035] Traditional guidance steps, when the vehicle does not allow interaction, are used to obtain the position of the vehicle in the parking lot, determine the vehicle's path, obtain the nearest guidance screen on the vehicle's path, and indicate the vehicle's direction and recommended parking space information on the guidance screen; when the vehicle does not allow interaction, multiple positioning base stations in the parking lot use wireless signal positioning technology, such as Bluetooth positioning or UWB (ultra-wideband) positioning, to obtain the precise position of the vehicle in the parking lot in real time. The system determines the vehicle's path by analyzing the vehicle's movement trajectory and speed. On the vehicle's path, the nearest guidance screen is quickly retrieved through collaborative work with the guidance screen control module. The guidance screen control module calculates the estimated time for the vehicle to arrive at the guidance screen based on the vehicle's position and direction of travel, and indicates the vehicle's direction of travel on the guidance screen in a graphic and textual manner. The guidance screen not only displays an arrow to indicate the direction of the vehicle's turn, but also displays the recommended parking space information closest to the current position, including the parking space number, the area where it is located, and the approximate distance from the guidance screen, so that the driver can make decisions quickly and find a suitable parking space smoothly. At the same time, the guidance screen will update the display content in real time according to the movement of the vehicle, ensuring that the driver can receive accurate guidance throughout the parking process.

[0036] The path planning strategy includes an automatic avoidance step. When a new vehicle enters the parking lot, it is used to obtain the path information of all running vehicles in the parking lot, generate a vehicle running trajectory map, and simultaneously predict the paths of all vehicles in the same time. Taking the lane intersection as a node, it determines whether the vehicles meet at the node, then generates a new path, and simultaneously predicts whether congestion will occur. If congestion is likely to occur, it recommends that the new vehicle adjust its speed to avoid congestion. When a new vehicle enters the parking lot, the parking lot management system quickly obtains the path information of all running vehicles in the parking lot. With the help of sensors installed at various key locations in the parking lot, such as geomagnetic sensors and cameras, the system continuously tracks the vehicle's driving trajectory and generates a detailed vehicle running trajectory map. At the same time, using the prediction algorithm, combined with the vehicle's current speed, direction and historical driving data, the future path of all vehicles in the same time is synchronously predicted. Taking the lane intersection in the parking lot as a key node, the system analyzes the predicted path of each vehicle to determine whether different vehicles will meet at the node. Once a possible encounter is detected, the system immediately regenerates the path for the new vehicle to avoid potential conflict points. In the process of generating a new path, the system also synchronously predicts whether the new path will cause congestion. If it is predicted that the new route is prone to congestion, the system will recommend the new vehicle to adjust its speed through the vehicle interaction module (if the vehicle allows interaction) or the guidance screen (if the vehicle does not allow interaction), such as slowing down appropriately or waiting in a specific section of the road, so as to avoid congested sections and ensure smooth passage of vehicles in the parking lot.

[0037] The path planning strategy also includes an optimization step. The optimization step is used to obtain vehicle requirements. According to the vehicle requirements, the best parking position is selected, and vehicle requirements are obtained. The vehicle requirements include the remaining battery power of the vehicle and the estimated stay time. According to the remaining battery power of the vehicle and the estimated stay time, through priority ranking, the vehicles are ranked in priority. Vehicles with lower remaining battery power or shorter estimated stay time are given priority to enter the fast charging parking spaces. This step focuses on vehicle requirements and aims to select the best parking position for the vehicle. The system obtains the key requirement information of the vehicle, including the remaining battery power of the vehicle and the estimated stay time. For new energy vehicles, the remaining battery power is an important consideration factor, while the estimated stay time applies to all vehicle types. According to these requirements, the system ranks the vehicles through a priority ranking algorithm. New energy vehicles with lower remaining battery power are given priority to enter the fast charging parking spaces to ensure that the vehicles can replenish their power in time and avoid inconvenience caused by insufficient power. For vehicles with shorter estimated stay time, a certain priority is also given so that they can park and leave quickly, improving the turnover rate of the parking spaces. After determining the best parking position, the system combines the real-time traffic conditions in the parking lot and calculates the shortest path or the optimal path from the current position of the vehicle (i.e., the parking lot entrance) to the selected parking space. The evaluation criteria for the optimal path comprehensively consider factors such as the length of the distance, the number of turns, and whether it passes through busy areas. Finally, parking information including the parking position and the detailed optimal parking route is generated. The parking route is presented in the form of a sequence of coordinate points, and the driving direction and distance between each point are marked.

[0038] The traditional guidance step also includes an intelligent following strategy, which includes

[0039] A vehicle identification step, which obtains the information of all vehicles in the parking lot that require traditional guidance and their driving paths, and judges whether there is partial overlap in the driving time and vehicle paths. If there is overlap, a following instruction is issued, and based on the vehicle position, the leading vehicle information is determined. The parking lot management system continuously obtains the information of all vehicles in the parking lot that require traditional guidance, including vehicle position, driving speed, and complete driving paths, etc. Through in-depth analysis of these data, the system judges whether there is partial overlap in the driving time and vehicle paths of different vehicles. When it is found that there is an overlap in the vehicle paths, the system immediately issues a following instruction. At the same time, based on the current position of the vehicle, the system further determines the leading vehicle information. The leading vehicle is usually the vehicle that is at the front in the overlapping path segment and has a guiding driving direction. The system selects the vehicle that enters the overlapping path segment earliest as the leading vehicle from among the vehicles with overlapping paths through precise calculation and comparison of the vehicle positions.

[0040] Following vehicle guiding steps: During the path overlap stage, the guiding sign indicates the traveling direction of the vehicle, and the indicator light is always on; during the path overlap stage, the guiding screen plays a crucial guiding role. The indicator lights on the guiding screen for indicating the traveling direction of the vehicle remain in the always-on state, providing continuous and clear direction guidance for the following vehicles. The driver of the following vehicle only needs to drive in the direction indicated by the indicator lights on the guiding screen to follow the leading vehicle along the established overlapping path. This always-on indicator light mode enables the driver to always clearly understand the forward direction in a complex parking lot environment, reducing confusion and bewilderment during driving.

[0041] Intelligent vehicle separation steps: Identify the vehicle in the vehicle fleet that needs to change lanes. When the vehicle approaches the lane-changing intersection, the indicator light flashes and switches to the current vehicle's passing direction. After detecting that the vehicle has passed, the guiding sign changes the indicated direction to the next vehicle's passing direction. The system continuously monitors the driving status of each vehicle in the fleet and accurately obtains the information of the vehicle that needs to change lanes. When it detects that a vehicle is about to approach the lane-changing intersection, the indicator lights on the guiding screen immediately change from the always-on state to the flashing state. At the same time, the indicated direction of the indicator lights quickly switches to the passing direction of the vehicle that needs to change lanes at present. This flashing and direction-changing indicator light can attract the driver's full attention, ensuring that they can make a lane-changing operation in a timely manner. After the system detects that the vehicle has successfully passed, the guiding screen changes the indicated direction again, returning to the passing direction of the next vehicle on the current path, and continues to provide accurate guiding services for the subsequent vehicles, ensuring the orderly passage of the entire vehicle fleet in a complex parking lot environment.

[0042] The intelligent vehicle following strategy also includes a dynamic adjustment step, which is used to obtain fleet information. When a new vehicle joins the overlapping path during the vehicle following process, the vehicle following speed is readjusted to enable the vehicle to join the vehicle following fleet. And a vehicle distance detection step is set to obtain the vehicle following distance. When the vehicle following distance is less than the threshold, an alarm is issued. When the system detects that a new vehicle enters the overlapping path, the dynamic adjustment process is immediately started. First, the system quickly analyzes information such as the position and speed of the new vehicle and integrates it with the information of the existing fleet. Through complex algorithms, the system calculates the amount of speed adjustment that each vehicle needs to make to enable the new vehicle to smoothly join the vehicle following fleet. This calculation process comprehensively considers factors such as the current driving speed of the fleet, the distance between vehicles, and the road conditions in the parking lot. For example, if the current driving speed of the fleet is relatively fast and the distance between the vehicles in front of the position where the new vehicle joins is small, the system may appropriately reduce the overall speed of the fleet while accelerating the new vehicle to complete the merging as soon as possible under the premise of safety. Then, through the guidance screen control module, the system sends instructions to the guidance screens on the paths where the relevant vehicles are located. The guidance screen will convey the speed adjustment information to the driver in a specific display mode, such as a flashing arrow combined with a digital prompt, informing the driver whether to accelerate, decelerate, or maintain the current speed, so as to enable the new vehicle to smoothly integrate into the vehicle following fleet and ensure the smoothness and safety of the fleet's driving; The system has preset a threshold for the safe vehicle following distance. This threshold is not fixed but is dynamically adjusted according to factors such as the road conditions in the parking lot (such as curves, straight roads, slopes, etc.), vehicle types (small cars, large vehicles), and the current traffic flow. For example, at curves or when the traffic flow is large, the threshold will be appropriately increased to ensure that the vehicle has enough safety distance to cope with emergencies; For large vehicles, since their braking distances are longer, the threshold will also be increased accordingly. When the system detects that the vehicle following distance is less than the set threshold, the alarm mechanism is immediately triggered. The alarm is displayed through the guidance screen. The guidance screen will switch to a prominent red background and display the words "The vehicle distance is too close. Please keep a safe distance" in large letters, and at the same time play a sharp alarm sound to attract the driver's high attention. In addition, the system will also send a voice alarm to the drivers in the relevant areas through the broadcast system in the parking lot, reminding the drivers in multiple ways to adjust the vehicle speed in time and keep a safe vehicle distance, effectively avoiding traffic accidents such as rear-end collisions.

[0043] Vehicle information includes vehicle license plate, Bluetooth, and magnetic card identification information.

[0044] The guiding sign is used to display the nearest parking space information, parking space number, and parking space direction guidance assigned by the system. Using the guiding sign is convenient for the intelligent guidance of vehicles that cannot interact with the system and for obtaining parking information.
