Description

Technical Field

[0001] This invention relates to the field of shared vehicle technology, and in particular to a method, device, and shared vehicle for positioning correction. Background Technology

[0002] Simply put, "electronic fences for shared vehicles" create virtual parking zones. Users must park the vehicle within these designated areas; otherwise, they cannot lock the car and end their trip. Returning the vehicle relies primarily on its location information. The vehicle can only be successfully returned if its location is within the virtual parking zone. However, due to GPS drift, the vehicle may be within the parking area, but its location information may show it outside, preventing the user from returning the car.

[0003] Currently, beacon-assisted positioning is commonly used to correct the location of shared vehicles. This involves laying auxiliary beacons in the parking area. When GPS is inaccurate or deviates, the beacons help correct the vehicle's location information, thereby reducing the probability of users failing to return the vehicle due to GPS drift. However, this method requires additional auxiliary beacons, which is costly, and laying beacons on the road also poses certain safety hazards. Summary of the Invention

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0041] Currently, beacon-assisted positioning is commonly used to correct the location of shared vehicles. This involves laying auxiliary beacons in the parking area. When GPS is inaccurate or deviates, the beacons help correct the vehicle's location information, thereby reducing the probability of users failing to return the vehicle due to GPS drift. However, this method requires additional auxiliary beacons, which is costly, and laying beacons on the road also poses certain safety hazards.

[0042] In addition, some methods use high-precision positioning chips to achieve sub-meter level positioning accuracy, thereby improving the success rate of users returning the vehicle. However, this method also requires the addition of high-precision positioning chips, which is costly.

[0043] In response, this invention provides a method for correcting the location of shared vehicles. Figure 1 This is a flowchart illustrating the shared vehicle location correction method provided by the present invention, as shown below. Figure 1 As shown, the method includes the following steps:

[0044] Step 110: Obtain Bluetooth broadcast information from multiple candidate vehicles in the parking area. The Bluetooth broadcast information is sent in real time by the Bluetooth modules of each candidate vehicle.

[0045] Here, "vehicles to be corrected" refers to shared vehicles that require location correction, while "candidate vehicles" refers to vehicles within the parking area. Bluetooth broadcast information is transmitted in real-time via the Bluetooth modules of candidate vehicles, and it can be used to characterize the location information of these candidate vehicles.

[0046] The Bluetooth modules of candidate vehicles transmit Bluetooth broadcast information in real time. However, the Bluetooth broadcast information transmitted by the Bluetooth module is limited by distance. That is, the vehicle to be corrected can only receive Bluetooth broadcast information from multiple candidate vehicles in the parking area when the vehicle to be corrected enters the detection range of the Bluetooth module. For example, if the vehicle to be corrected enters the parking area or the distance between the vehicle to be corrected and the candidate vehicles is within a preset distance range, the vehicle to be corrected can obtain Bluetooth broadcast information from multiple candidate vehicles in the parking area.

[0047] Step 120: Based on the location information of each candidate vehicle carried in the Bluetooth broadcast information and the location information of the vehicle to be corrected, determine whether the location information of the vehicle to be corrected has drifted.

[0048] Specifically, the Bluetooth broadcast information carries the location information of each candidate vehicle. Based on the location information of each candidate vehicle and the location information of the vehicle to be corrected, the distance between the vehicle to be corrected and each candidate vehicle can be determined.

[0049] Since the vehicle to be corrected can receive Bluetooth broadcast information from each candidate vehicle, it indicates that the vehicle to be corrected is within the detection range of the Bluetooth modules of each candidate vehicle; that is, the distance between the vehicle to be corrected and each candidate vehicle is less than or equal to a preset distance. In this case, if the distance between the vehicle to be corrected and each candidate vehicle, determined based on the location information of both candidate vehicles, is greater than the preset distance, it indicates that the location information of the vehicle to be corrected has an error, meaning that the location information has drifted and needs to be corrected. The preset distance characterizes the detection range of the Bluetooth modules of each candidate vehicle.

[0050] Step 130: If it is determined that the positioning information of the vehicle to be corrected has drifted, a reference vehicle is determined from the candidate vehicles based on the confidence level of the positioning information of each candidate vehicle.

[0051] Specifically, if it is determined that the location information of the vehicle to be corrected has drifted, it indicates that there is an error in the location information of the vehicle to be corrected, that is, the location information of the vehicle to be corrected needs to be corrected.

[0052] The confidence level of the location information of each candidate vehicle is used to characterize the accuracy of the location information of each candidate vehicle. The higher the confidence level, the higher the accuracy of the location information of the corresponding candidate vehicle. Optionally, the candidate vehicle with the highest confidence level can be used as the reference vehicle, or multiple candidate vehicles with confidence levels greater than the threshold can be used as the reference vehicle. This embodiment of the invention does not specifically limit this.

[0053] Step 140: Based on the location information of the reference vehicle, correct the location information of the vehicle to be corrected.

[0054] Specifically, since the location information of the reference vehicle has a high confidence level, the location information of the vehicle to be corrected can be corrected based on the location information of the reference vehicle. If the reference vehicle is the candidate vehicle corresponding to the highest confidence level, the distance between the reference vehicle and the vehicle to be corrected can be detected based on its Bluetooth module. Then, based on the location information of the reference vehicle with a high confidence level, the actual location information of the vehicle to be corrected can be determined, and the location information of the vehicle to be corrected can be corrected based on this actual location information. If there are multiple candidate vehicles with a confidence level greater than a threshold, the distance between each reference vehicle and the vehicle to be corrected can be detected based on its Bluetooth module. Then, based on the location information of the reference vehicle with a high confidence level, the location information of the vehicle to be corrected under different reference vehicles can be determined, and the actual location information of the vehicle to be corrected can be determined based on the location information of the vehicle to be corrected under different reference vehicles. For example, the centroid of the location information of the vehicle to be corrected under different reference vehicles can be used as the actual location information of the vehicle to be corrected, and the location information of the vehicle to be corrected can be corrected based on this actual location information.

[0055] The shared vehicle location correction method provided in this invention, based on the location information of each candidate vehicle carried in Bluetooth broadcast information and the location information of the vehicle to be corrected, can accurately determine whether the location information of the vehicle to be corrected has drifted. Furthermore, if it is determined that the location information of the vehicle to be corrected has drifted, the method accurately corrects the location information of the drifting vehicle based on the location information of a reference vehicle with high confidence, avoiding the problems of high cost and safety hazards associated with adding auxiliary beacons in traditional methods.

[0056] Based on the above embodiments, based on the location information of each candidate vehicle carried in the Bluetooth broadcast information and the location information of the vehicle to be corrected, determining whether the location information of the vehicle to be corrected has drifted includes:

[0057] Based on the location information of each candidate vehicle and the location information of the vehicle to be corrected, the distance between the vehicle to be corrected and each candidate vehicle is determined.

[0058] If the distance between the vehicle to be corrected and each candidate vehicle is greater than a preset distance, it is determined that the positioning information of the vehicle to be corrected has drifted.

[0059] Specifically, the Bluetooth broadcast information carries the location information of each candidate vehicle. Based on the location information of each candidate vehicle and the location information of the vehicle to be corrected, the distance between the vehicle to be corrected and each candidate vehicle can be determined.

[0060] Since the vehicle to be corrected can receive Bluetooth broadcast information from each candidate vehicle, it indicates that the vehicle to be corrected is within the detection range of the Bluetooth modules of each candidate vehicle, that is, the distance between the vehicle to be corrected and each candidate vehicle is less than or equal to the preset distance.

[0061] In this case, if the distance between the vehicle to be corrected and each candidate vehicle, determined based on the location information of each candidate vehicle and the location information of the vehicle to be corrected, is greater than a preset distance, it indicates that there is an error in the location information of the vehicle to be corrected, that is, the location information of the vehicle to be corrected has drifted, and the location information of the vehicle to be corrected needs to be corrected. The preset distance is used to characterize the detection range of the Bluetooth module of each candidate vehicle; that is, the preset distance can be determined based on the detection range of the Bluetooth module. For example, the preset distance can be set to 10m, or it can be set to other values. This embodiment of the invention does not specifically limit this.

[0062] Based on any of the above embodiments, the confidence level of the location information of each candidate vehicle is determined based on the following steps:

[0063] The number of first candidate vehicles and the number of second candidate vehicles are determined. The number of first candidate vehicles is the number of other candidate vehicles detected by the Bluetooth module of each candidate vehicle within a preset distance range, and the number of second candidate vehicles is the number of other candidate vehicles detected by the GPS module of each candidate vehicle within a preset distance range.

[0064] Based on the number of first candidate vehicles and the number of second candidate vehicles, the confidence level of the location information of each candidate vehicle is determined.

[0065] Specifically, the first candidate vehicle number is the number of other candidate vehicles detected by the Bluetooth module of each candidate vehicle within a preset distance range, and the second candidate vehicle number is the number of other candidate vehicles detected by the GPS module of each candidate vehicle within a preset distance range.

[0066] If the number of first candidate vehicles is the same as the number of second candidate vehicles, it means that the candidate vehicles detected by the Bluetooth module and GPS module of the corresponding candidate vehicle are the same. In other words, the location information detected by the GPS module of the corresponding candidate vehicle has a high degree of confidence.

[0067] If the number of first candidate vehicles differs significantly from the number of second candidate vehicles, it indicates that the Bluetooth and GPS modules of the corresponding candidate vehicles detect a large difference in the candidate vehicles detected. In other words, the GPS module of the corresponding candidate vehicle has an error in positioning, resulting in a low confidence level of the positioning information obtained based on the GPS module, and thus a low confidence level of the positioning information of the corresponding candidate vehicle.

[0068] Based on any of the above embodiments, the positioning information of the vehicle to be corrected is corrected based on the positioning information of the reference vehicle, including:

[0069] Determine the actual distance between the reference vehicle and the vehicle to be corrected. The actual distance is detected by the Bluetooth module of the reference vehicle.

[0070] Based on the actual distance and the location information of the reference vehicle, the location information of the vehicle to be corrected is adjusted.

[0071] Specifically, the Bluetooth module of the reference vehicle can detect the actual distance between the reference vehicle and the vehicle to be corrected. Since the location information of the reference vehicle has a high confidence level, its current position can be determined based on the location information of the reference vehicle. Based on the actual distance between the reference vehicle and the vehicle to be corrected, the current position of the vehicle to be corrected can be obtained, thereby acquiring the actual location information of the vehicle to be corrected and realizing the correction of the location information of the vehicle to be corrected.

[0072] Based on any of the above embodiments, based on the actual distance and the positioning information of the reference vehicle, the positioning information of the vehicle to be corrected is corrected, including:

[0073] Based on the actual distance and the location information of the reference vehicle, determine the actual location information of the vehicle to be corrected;

[0074] Based on the actual location information of the vehicle to be corrected, the location information of the vehicle to be corrected is corrected.

[0075] Specifically, the actual location information of the vehicle to be corrected is used to characterize its current actual location. The Bluetooth module of the reference vehicle can detect the actual distance between the reference vehicle and the vehicle to be corrected. Based on the location information of the reference vehicle, its current location can be determined, and based on the actual distance between the reference vehicle and the vehicle to be corrected, the current location of the vehicle to be corrected can be obtained, thereby acquiring the actual location information of the vehicle to be corrected and realizing the correction of the location information of the vehicle to be corrected.

[0076] Based on any of the above embodiments, the positioning information of the vehicle to be corrected is corrected, and then the process further includes:

[0077] Based on the corrected location information of the vehicle to be corrected, determine whether the vehicle to be corrected is located within the parking area;

[0078] Once it is confirmed that the vehicle to be corrected is located within the parking area, a successful return instruction is sent to the client.

[0079] Specifically, after the location information of the vehicle to be corrected is corrected, the corrected location information of the vehicle to be corrected can be considered accurate, and then it can be determined whether the vehicle to be corrected is located in the parking area based on the corrected location information of the vehicle to be corrected.

[0080] If the vehicle to be repaired is located within the parking area, it indicates that the vehicle can be returned at this time, and a successful return instruction is sent to the client so that the user is notified that the vehicle has been successfully returned.

[0081] Based on any of the above embodiments, the present invention also provides a method for correcting the location of shared vehicles, such as... Figure 2 As shown, the method includes:

[0082] First, the Bluetooth module of the vehicle to be corrected receives Bluetooth broadcast information from the Bluetooth modules of other candidate vehicles in the parking area, and obtains the location information (i.e., GPS information) of other candidate vehicles from the Bluetooth broadcast information sent by the Bluetooth modules of other candidate vehicles.

[0083] Next, based on the location information of the vehicle to be corrected and the location information of other candidate vehicles, the distance between the vehicle to be corrected and the other candidate vehicles is determined. If the distance between the vehicle to be corrected and the other candidate vehicles is greater than a preset distance (e.g., 10m), it indicates that the location information of the vehicle to be corrected has drifted.

[0084] If the location information of the vehicle to be corrected is determined to have drifted, the confidence level of the location information of each candidate vehicle is determined based on the number of first candidate vehicles and the number of second candidate vehicles, and the candidate vehicle with the highest confidence level is used as the reference vehicle. The number of first candidate vehicles is the number of other candidate vehicles detected by the Bluetooth module of each candidate vehicle within a preset distance range, and the number of second candidate vehicles is the number of other candidate vehicles detected by the GPS module of each candidate vehicle within a preset distance range.

[0085] Finally, based on the location information of the reference vehicle, the location information of the vehicle to be corrected is corrected, and based on the corrected location information of the vehicle to be corrected, it is determined whether the vehicle to be corrected is within the parking area.
