In the case that the first distance is greater than the second distance, and the driving duration of the vehicle from the first travel point to the second travel point is greater than a preset duration, the vehicle travel calibration device calibrates a vehicle travel based on the starting point and the first travel point. That is, when the distance between the starting point and the travel point starts to decrease, and the corresponding travel duration is relatively long, it is considered that the vehicle has entered a new travel, and therefore, the last travel point and the starting point are calibrated as a real travel of a vehicle.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0029] It should also be noted that in the embodiments of this application, "of", "corresponding", and "corresponding" can sometimes be used interchangeably. It should be pointed out that when their differences are not emphasized, their meanings are consistent.

[0030] To facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish the same or similar items with essentially the same function and effect. Those skilled in the art can understand that the terms "first" and "second" are not intended to limit the quantity or execution order.

[0031] Before providing a detailed explanation of the embodiments of this application, some related technologies involved in the embodiments of this application will be introduced first.

[0032] Vehicle Internet of Things (V2X): The concept of V2X originates from the Internet of Things, namely the Internet of Vehicles. It uses vehicles in motion as information sensing objects and leverages next-generation information and communication technologies to achieve network connections between vehicles and X (i.e., vehicles, people, roads, and service platforms). This improves the overall intelligent driving level of vehicles, provides users with a safe, comfortable, intelligent, and efficient driving experience and transportation services, and at the same time improves traffic operation efficiency and enhances the intelligence level of social transportation services.

[0033] The Internet of Vehicles (IoV) utilizes next-generation information and communication technologies to achieve comprehensive network connectivity between vehicles and cloud platforms, between vehicles themselves, between vehicles and roads, between vehicles and people, and within vehicles. It primarily achieves "triple play," integrating the in-vehicle network, the inter-vehicle network, and the in-vehicle mobile internet. The IoV uses sensing technology to perceive vehicle status information and leverages wireless communication networks and modern intelligent information processing technologies to achieve intelligent traffic management, intelligent decision-making for traffic information services, and intelligent vehicle control.

[0034] Big data, also known as massive data, refers to data of such a large scale that it is impossible to capture, manage, process, and organize it into information that helps users make more proactive decisions within a reasonable timeframe using mainstream software tools.

[0035] With the rapid development of vehicle networking and big data technologies, it has become increasingly easy to obtain data on vehicles during their operation (including driving time, geographical location, speed, etc.).

[0036] However, it remains difficult to pinpoint the actual vehicle journey (also known as the actual business journey, i.e. the actual transportation process of a vehicle) based on massive amounts of data.

[0037] For example, a vehicle loads goods, departs from point A, passes through point B, arrives at point C, and unloads the goods. Then, the vehicle returns to point B to rest. From a data perspective, the vehicle's route is: A→B→C→B. However, identifying the vehicle's actual operational journey from this route to understand the actual process of a single transport operation, and thus laying the groundwork for improving transportation efficiency and reducing costs, is clearly beyond the scope of data analysis alone.

[0038] In some related technologies, the actual vehicle journey can be determined by manually investigating the vehicle's route. For example, through manual investigation, it is learned that the vehicle's transportation task was to transport goods from point A to point C, and after completing the transport, the vehicle went to point B for rest. Therefore, after obtaining the vehicle's route as A→B→C→B, this route can be marked to obtain the vehicle's actual journey as A→B→C.

[0039] However, manual surveys are costly and have a time lag, so they cannot be widely adopted.

[0040] In view of this, this application provides a vehicle travel calibration method, which aims to use technical means to calibrate the actual travel of a vehicle, thereby reducing labor costs.

[0041] The vehicle trip calibration provided in this application embodiment can be applied to vehicle networking systems. Figure 1 A schematic diagram of one structure of the vehicle networking system is shown. For example... Figure 1 As shown, the vehicle networking system 10 includes a vehicle 11, a server 12, and a vehicle trip calibration (hereinafter referred to as calibration device) 13. The vehicle 11 is communicatively connected to the server 12, and the server 12 is communicatively connected to the calibration device 13.

[0042] Vehicle 11 is equipped with intelligent in-vehicle devices, such as a Telematics Box (T-BOX), which can acquire real-time data such as vehicle location, mileage, fuel consumption, and engine speed, and send this data to server 12.

[0043] Server 12 can be a standalone server, a server cluster or distributed system consisting of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms.

[0044] The calibration device 13 can be any electronic device with data processing capabilities, including but not limited to tablet computers, desktop computers, laptop computers, handheld computers, etc.

[0045] In different application scenarios, the server 12 and the calibration device 13 can be independent devices or integrated into the same device. This application embodiment does not specifically limit this.

[0046] When server 12 and calibration device 13 are integrated into the same device, the data transmission method between server 12 and calibration device 13 is the same as the data transmission between modules within the device. In this case, the data transmission process between the two is the same as the data transmission process when server 12 and calibration device 13 are independent of each other.

[0047] In the following embodiments provided in this application, the server 12 and the calibration device 13 are described as being configured independently of each other.

[0048] Figure 2 This is a flowchart illustrating a vehicle trip calibration method according to some exemplary embodiments. In some embodiments, the above-described vehicle trip calibration method can be applied to, for example... Figure 1 The calibration device and server shown can also be applied to other similar devices.

[0049] like Figure 2 As shown, the vehicle travel calibration method provided in this application includes the following steps S201-S203.

[0050] S201, The calibration device obtains the vehicle's travel route.

[0051] The itinerary includes a starting point and multiple travel points.

[0052] As one possible implementation, the calibration device obtains the vehicle's travel route from the server.

[0053] For example, the server receives real-time driving information reported by the vehicle. This driving information may include the vehicle's location, engine speed, fuel consumption, mileage, etc. Furthermore, the server processes the driving information over a period of time to obtain the travel route, including the starting point and multiple travel points. Therefore, the calibration device can obtain the vehicle's travel route from the server.

[0054] like Figure 3 As shown, a travel route is illustrated, which includes a starting point 1, a travel point 2, and a travel point 3. The starting point 1 represents the vehicle's initial position, the travel point 2 represents a position of the vehicle during its journey, and the travel point 3 represents another position of the vehicle during its journey.

[0055] As another possible implementation, the calibration device obtains the vehicle's driving information within a preset time period from the server, and obtains the vehicle's travel route based on the obtained information.

[0056] The specific implementation method of this step can be found in the following embodiments, and will not be repeated here.

[0057] Understandably, the above-mentioned route is obtained by the calibration device or server based on a large amount of vehicle driving data. This route is relatively generalized and has low representativeness, and cannot reflect the actual driving process of the vehicle completing a transportation trip.

[0058] S202, The calibration device determines the first distance between the starting point and the first travel point, and the second distance between the starting point and the second travel point.

[0059] The first travel point and the second travel point are any two adjacent travel points among multiple travel points, and the time when the vehicle passes through the first travel point is before the time when the vehicle passes through the second travel point.

[0060] As one possible implementation, the calibration device acquires the position of the starting point, the position of the first travel point, and the position of the second travel point. Further, the calibration device calculates a first distance between the starting point and the first travel point based on the position of the starting point, the position of the first travel point, and a preset distance formula; and calculates a second distance between the starting point and the second travel point based on the position of the starting point, the position of the second travel point, and the preset distance formula.

[0061] For example, such as Figure 4 The diagram illustrates the distances between travel points. Solid lines represent the vehicle's travel route, which includes starting point 1, travel point 1, travel point 2, travel point 3, and travel point 4. Dashed lines represent the distances between starting point 1 and each travel point.

[0062] In some embodiments, the positions of the starting point and travel points can be represented by latitude and longitude. After obtaining the latitude and longitude of the starting point and each travel point, the calibration device can calculate the distance between the starting point and any travel point according to the Haversine formula or the Vincenty formula.

[0063] It should be noted that while the Vincenty formula offers higher accuracy than the Haversine formula, it also has greater complexity and requires more computation. The Haversine formula, while simpler and not achieving the same level of accuracy as the Vincenty formula, reduces computational complexity. This application does not limit the choice of formula in its embodiments.

[0064] For example, the calibration device can calculate the distance between the starting point and any travel point according to the Haversine formula, as follows:

[0065]

[0066] Where d represents the distance between the two points, and r represents the Earth's radius. λ1 and λ2 represent the latitude of the starting point (in radians) and the latitude of the travel point (in radians), respectively.

[0067] S203. When the first distance is greater than the second distance and the travel time from the first travel point to the second travel point is greater than the preset time, the calibration device calibrates one vehicle journey based on the starting point and the first travel point.

[0068] As one possible implementation, the calibration device compares a first distance with a second distance to determine whether the first distance is greater than the second distance. If the first distance is greater than the second distance, the calibration device obtains the travel time of the vehicle from the first travel point to the second travel point and determines whether this travel time is greater than a preset time. If the travel time is greater than the preset time, the calibration device calibrates the journey between the starting point and the first travel point as one actual journey of the vehicle (i.e., completing one actual transportation trip).

[0069] For example, refer to Figure 4 As the vehicle travels from starting point 1 to travel points 1, 2, and 3, the distance between the starting point and each travel point continuously increases. However, when the vehicle reaches travel point 4, the distance between the starting point and the travel point has decreased, and the travel time from travel point 3 to travel point 4 exceeds 30 minutes. Therefore, the calibration device uses the journey from starting point 1 to travel point 3 as a true journey for calibration, thus defining a true journey. Travel point 3 can then be used as the starting point for the next true journey, and calibration can begin anew.

[0070] The embodiments of this application provide at least the following beneficial effects: The vehicle trip calibration device acquires a trip route including a starting point and multiple trip points. Further, the vehicle trip calibration device determines a first distance between the starting point and a first trip point, and a second distance between the starting point and a second trip point; wherein the first and second trip points are any two adjacent trip points among the multiple trip points, and the time the vehicle passes the first trip point is before the time the vehicle passes the second trip point. When the first distance is greater than the second distance, and the travel time from the first trip point to the second trip point is greater than a preset time, the vehicle trip calibration device calibrates a vehicle trip based on the starting point and the first trip point. That is, when the distance between the starting point and the trip point begins to decrease, and the corresponding travel time is relatively long, it is considered that the vehicle has entered a new trip; therefore, the previous trip point and the starting point are calibrated as a real vehicle trip. In this way, this application utilizes technical means to calibrate the real vehicle trip, thereby reducing labor costs.

[0071] In one design, in order to obtain the vehicle's travel route, such as Figure 5 As shown, S201 specifically includes S2011-S2012.

[0072] S2011, The calibration device acquires the vehicle's driving information within a preset time period.

[0073] The driving information includes the vehicle's location and engine speed.

[0074] As one possible implementation, the calibration device obtains the vehicle's driving information within a preset time period from the server.

[0075] In some embodiments, the server can receive raw driving data reported by vehicles in real time, parse and transform the raw driving data into formatted data, and store it in a data warehouse (such as a Hive table) for later use. Since the raw driving data reported by vehicles may contain omissions, missing data, deviations, or data formats that are not directly usable, the server also needs to perform data warehouse techniques (Extract-Transform-Load, ETL) operations such as cleaning, filtering, and transformation on the raw driving data reported by vehicles. Furthermore, the server utilizes big data distributed technologies such as Spark and Hive to process the massive amounts of raw driving data to a usable level, enabling the calibration device to successfully obtain the vehicle's driving information within a preset time period from the server.

[0076] S2012. The calibration device obtains the vehicle's travel route based on the vehicle's driving information.

[0077] As one possible implementation, the calibration device determines the starting point as the position corresponding to the start time of the vehicle within a preset time period. Furthermore, the calibration device determines the vehicle's start-stop state based on its rotational speed, and determines the travel points as the positions corresponding to changes in the start-stop state within the preset time period.

[0078] The start / stop status includes the start status and the off status.

[0079] Specifically, when the engine speed is greater than or equal to the preset speed, the calibration device determines that the vehicle is in the starting state; when the engine speed is less than the preset speed, the calibration device determines that the vehicle is in the off state.

[0080] For example, assuming a preset engine speed of 500 rpm, the calibration device determines that the vehicle is in a running state when the vehicle speed is greater than or equal to 500 rpm; and determines that the vehicle is in a turned-off state when the vehicle speed is less than 500 rpm. Furthermore, the calibration device determines the positions corresponding to the changes in start-stop state within a preset time period as travel points.

[0081] Understandably, if the vehicle's engine speed remains above 500 rpm for a period of time, the calibration device can determine that the vehicle is in operation. Connecting the points where the vehicle is in operation consecutively forms an operating cycle, until the vehicle is turned off. Therefore, the calibration device only needs to determine the positions corresponding to the changes in start-stop status and use these positions as travel points to obtain the vehicle's travel route.

[0082] The above embodiments mainly describe the solutions provided by the embodiments of this application from the perspective of an apparatus (device).
