Description

Technical Field

[0001] The present invention relates to the technical field of facility assessment, and in particular to a vehicle energy replenishment facility assessment method, device and computer-readable storage medium. Background Art

[0002] When vehicle users choose energy replenishment facilities to replenish their vehicles, such as charging their vehicles, they usually analyze the pros and cons of different energy replenishment facilities based on the evaluation indicators of the energy replenishment facilities, and thus select high-quality energy replenishment facilities. At present, the conventional vehicle energy replenishment facility evaluation method mainly collects the operating parameters of the energy replenishment facilities (for example: the charging speed of the charging facilities, the charging success rate, etc.), and evaluates based on the collected operating parameters. However, in actual applications, there may be other factors such as the closure of the location where the energy replenishment facility is located and the parking space to which the energy replenishment facility belongs is occupied, resulting in the problem that even if the user chooses a high-quality energy replenishment facility, the energy replenishment facility cannot be used. Therefore, the conventional vehicle energy replenishment facility evaluation method can only be evaluated based on the operating parameters of the energy replenishment facility, and cannot consider the above-mentioned external factors that are not related to the status of the energy replenishment facility itself and can affect the use of the energy replenishment facility, resulting in this method being unable to conduct a comprehensive and accurate evaluation of the pros and cons of the energy replenishment facility.

[0097] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0098] In the description of the present invention, "module" and "processor" may include hardware, software or a combination of the two. A module may include hardware circuits, various suitable sensors, communication ports, and memories, and may also include software parts, such as program codes, or a combination of software and hardware. The processor may be a central processing unit, a microprocessor, an image processor, a digital signal processor, or any other suitable processor. The processor has data and / or signal processing functions. The processor may be implemented in software, hardware, or a combination of the two. Non-temporary computer-readable storage media include any suitable medium that can store program codes, such as a magnetic disk, a hard disk, an optical disk, a flash memory, a read-only memory, a random access memory, and the like. The term "A and / or B" means all possible combinations of A and B, such as only A, only B, or A and B. The term "at least one A or B" or "at least one of A and B" has a similar meaning to "A and / or B", and may include only A, only B, or A and B. The singular terms "one" and "the" may also include plural forms.

[0099] Here we first explain some terms involved in this invention

[0100] Vehicle energy replenishment facilities refer to facilities that can provide energy to the vehicle's driving energy device in order to drive the energy device to store energy. Vehicle energy replenishment facilities include but are not limited to: charging facilities, battery replacement facilities, charging and battery replacement facilities, refueling facilities, etc. For example: if the vehicle is an electric car, then the vehicle energy replenishment facility can be a charging pile or a charging pile cluster; if the vehicle is a gasoline car, then the vehicle energy replenishment facility can be a gas station.

[0101] At present, the conventional vehicle energy replenishment facility evaluation method is mainly based on the operating parameters of the vehicle energy replenishment facility (for example: the charging speed of the charging facility, the charging success rate, etc.), and the vehicle user selects the high-quality vehicle energy replenishment facility for energy replenishment based on the evaluation results. However, in actual applications, even if the user selects a high-quality vehicle energy replenishment facility, when driving to the energy replenishment facility, the user may not be able to use the energy replenishment facility due to other factors such as the closure of the location of the energy replenishment facility or the occupation of the parking space to which the energy replenishment facility belongs. In other words, the conventional vehicle energy replenishment facility evaluation method cannot accurately evaluate the quality of vehicle energy replenishment facilities.

[0102] In an embodiment of the present invention, it is possible to analyze whether the vehicle passes through other vehicle energy replenishment facilities based on the driving trajectory data of the vehicle within a period of time before the vehicle is recharged, and to evaluate whether these other vehicle energy replenishment facilities that the vehicle has passed through are unavailable vehicle energy replenishment facilities based on the analysis results. Specifically, first, the driving time period in which the vehicle speed is less than or equal to the preset vehicle speed threshold and the corresponding driving path are obtained based on the driving trajectory data, and then it is determined whether the waypoints in the driving path include other vehicle energy replenishment facilities other than the vehicle energy replenishment facility used by the vehicle for energy replenishment, and finally, it is evaluated whether these other vehicle energy replenishment facilities are unavailable vehicle energy replenishment facilities in the current driving time period based on the judgment results. If the vehicle speed on a certain driving path is less than or equal to the preset vehicle speed threshold and the waypoints in the driving path also include other vehicle energy replenishment facilities, this indicates that the vehicle has the intention to recharge the vehicle at this other vehicle energy replenishment facility, but the energy replenishment facility that the vehicle finally chooses to use is not this other vehicle energy replenishment facility, which further indicates that this other vehicle energy replenishment facility may be an energy replenishment facility that cannot be used due to reasons such as the closure of the place where the energy replenishment facility is located, the parking space to which the energy replenishment facility belongs is occupied, and an operating failure occurs.

[0103] See attached Figure 1 , Figure 1 FIG. 1 is a flow chart showing the main steps of a method for evaluating a vehicle charging facility according to an embodiment of the present invention. Figure 1 As shown, the vehicle energy replenishment facility evaluation method in the embodiment of the present invention mainly includes the following steps:

[0104] Step S101: Taking the start time of the vehicle recharging as the time starting point, the driving trajectory data of the vehicle within a preset time period before the start time is obtained.

[0105] The starting time of the vehicle's energy replenishment refers to the starting time of the vehicle's energy replenishment when the duration of the energy replenishment is greater than or equal to the preset duration. In other words, "vehicle energy replenishment" refers to the energy replenishment performed to meet the vehicle's regular energy replenishment needs, rather than a very short energy replenishment operation performed for the purpose of starting the energy replenishment facility test. It should be noted that those skilled in the art can flexibly set the specific duration of the preset duration, and such adjustment and change to the preset duration does not deviate from the principle and scope of the present invention, and should be limited within the scope of protection of the present invention. An example: the preset duration can be 2 minutes.

[0106] Step S102: Acquire a driving period in which the vehicle speed is less than or equal to a preset vehicle speed threshold and a corresponding driving path according to the driving trajectory data.

[0107] When a vehicle arrives near a charging facility to recharge, the vehicle speed is often relatively low or even reduced to zero. Therefore, in order to accurately analyze whether the vehicle has the intention to recharge, the preset vehicle speed threshold can be set to a smaller value, and the specific value of the preset vehicle threshold can be selected according to the actual situation. Such adjustment and change of the preset vehicle threshold does not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention. An example: the preset vehicle speed threshold is 0 or 1 m / s.

[0108] In this embodiment, the driving trajectory data may be data collected by a positioning device, and the positioning device includes but is not limited to a positioning device based on the Global Positioning System (GPS), a positioning device based on the BeiDou Navigation Satellite System (BDS), etc. The positioning device may be a positioning device pre-set on the vehicle, or a positioning device set in the background and capable of communicating with the vehicle, etc. In one embodiment, the driving time period when the vehicle speed is less than or equal to the preset vehicle speed threshold and the corresponding driving path may be obtained according to the following steps:

[0109] Step 11: Obtain vehicle positioning data from the driving trajectory data, where the vehicle positioning data includes the vehicle position and the driving time corresponding to each vehicle position.

[0110] In this embodiment, the vehicle positioning data may be a point set including the vehicle position and the driving time. For example, the vehicle positioning data may be shown as the following point set:

[0111] [(lng1, lat1, ts1), (lng2, lat2, ts2),..., (lngN, latN, tsN)]

[0112] Among them, (lng1, lat1) represents the vehicle position of the first positioning point in the point set, lng1 is the longitude of the vehicle position, and lat1 is the latitude of the vehicle position; ts1 represents the driving time of the first positioning point in the point set. The meanings of the parameters in the second to Nth positioning points are similar to those of the first positioning point, and will not be repeated here.

[0113] Step 12: According to each vehicle position and the corresponding driving time, the average vehicle speed on the driving path corresponding to the corresponding vehicle positions in the driving period between two adjacent driving times is calculated respectively.

[0114] In this embodiment, the average speed of the vehicle can be calculated based on the ratio of the driving distance to the driving time. For example, if the vehicle positioning data is the point set shown in step 11 above, the average speed v of the vehicle on the driving path corresponding to the first and second positioning points can be calculated according to the method shown in the following formula (1): 12 :

[0115]

[0116] The parameter "Distance()" in formula (1) represents a distance calculation function between two points. In this embodiment, a conventional distance calculation function in the mathematical field can be used to calculate the distance between two positioning points.

[0117] Step 13: According to the comparison result of the average vehicle speed corresponding to each driving time period and the preset speed threshold, the driving time period with the average vehicle speed less than or equal to the preset speed threshold and the corresponding driving path are obtained, that is, the average vehicle speed corresponding to each driving time period is compared with the preset speed threshold one by one to obtain the comparison result corresponding to each driving time period, and the driving time period with the comparison result of "the average vehicle speed is less than or equal to the preset speed threshold" and the corresponding driving path are selected as the "driving time period with the speed less than or equal to the preset speed threshold and the corresponding driving path" to be finally obtained.

[0118] Based on the above steps 11 to 13, the average speed of the vehicle on each driving path can be accurately calculated according to the vehicle positioning data, which is conducive to accurately analyzing the driving status of the vehicle on each driving path and analyzing whether the vehicle has the intention to replenish energy.

[0119] Step S103: Determine whether the waypoints in the driving path include other vehicle energy charging facilities other than the vehicle energy charging facilities used by the vehicle for energy charging, that is, determine whether the waypoints in the driving path where the vehicle speed (average vehicle speed) obtained in step S102 is less than or equal to the preset vehicle speed threshold include other vehicle energy charging facilities.

[0120] In one implementation, the following steps may be used to determine whether a waypoint in a driving path includes other vehicle energy charging facilities other than the vehicle energy charging facility used by the vehicle for energy charging:

[0121] First, the midpoint position of the driving path is obtained. Then, it is determined whether there are other vehicle charging facilities other than the vehicle charging facilities used by the vehicle for charging near the midpoint position; if so, it is determined that the waypoints in the current driving path include the above-mentioned other vehicle charging facilities.

[0122] In this embodiment, the facility location of each vehicle charging facility can be obtained in advance. After the midpoint location of the driving path is obtained, the location is matched with the facility location of each vehicle charging facility according to the midpoint location, and the location deviation between the midpoint location and each facility location is obtained. If the location deviation is less than or equal to the preset distance, it is determined that the vehicle charging facility corresponding to the current location deviation belongs to the charging facility near the midpoint location. The specific value of the preset distance can be selected according to the actual situation. Such adjustment and change of the preset distance does not deviate from the principle and scope of the present invention, and should be limited within the protection scope of the present invention. An example: the preset distance is 5 meters.

[0123] It should be noted that although this embodiment only provides a specific implementation method for obtaining vehicle energy replenishment facilities based on the midpoint position of the driving path. However, those skilled in the art will understand that the protection scope of the present invention is obviously not limited to this specific implementation method. Those skilled in the art can select other positions in the driving path to obtain vehicle energy replenishment facilities according to actual needs. For example, the midpoint position is replaced with the starting position or the ending position of the driving path. The technical solutions after these changes or replacements will fall within the protection scope of the present invention.

[0124] Step S104: evaluating whether the other vehicle energy replenishing facilities are unavailable vehicle energy replenishing facilities during the driving period according to the judgment result, that is, evaluating whether these other vehicle energy replenishing facilities are unavailable vehicle energy replenishing facilities according to the judgment result of step S103.

[0125] In this embodiment, if it is determined that the waypoints in the driving path where the vehicle speed is less than or equal to the preset vehicle speed threshold also include other vehicle energy charging facilities, it indicates that the vehicle has the intention to recharge the vehicle at this other vehicle energy charging facility, but the energy charging facility finally selected by the vehicle is not this other vehicle energy charging facility, which further indicates that this other vehicle energy charging facility may be an energy charging facility that cannot be used due to reasons such as the closure of the place where the energy charging facility is located, the parking space to which the energy charging facility belongs is occupied, or an operating failure occurs. Therefore, after determining that other vehicle energy charging facilities are included, it can be directly determined that this other vehicle energy charging facility is an unavailable vehicle energy charging facility.

[0126] Furthermore, in order to accurately evaluate whether the other vehicle energy replenishment facilities obtained in step S103 are unavailable vehicle energy replenishment facilities, it is also possible to analyze whether the same unused vehicle energy replenishment facility is included in the driving path with a vehicle speed less than or equal to the preset vehicle speed threshold based on the driving trajectory data of different vehicles. If a certain vehicle energy replenishment facility is not used multiple times in a certain time period, it can be determined that the vehicle energy replenishment facility is an unavailable vehicle energy replenishment facility in this time period. Specifically, in one embodiment, when step S103 determines that the waypoints in the driving path include other vehicle energy replenishment facilities (other vehicle energy replenishment facilities other than the vehicle energy replenishment facilities used by the vehicle for energy replenishment), it can be determined whether the vehicle energy replenishment facility is an unavailable vehicle energy replenishment facility according to the following steps:

[0127] Step 21: Increase the number of unavailable tags of the other vehicle charging facilities. The unavailable tags include time information of the driving time period, and the unavailable tags indicate that the current vehicle charging facility cannot be used during the specified driving time period. The driving time period refers to the driving time period related to the other vehicle charging facilities determined by steps S102-S103.

[0128] The number increase process refers to increasing the data based on the current number of unavailable tags to obtain a new number of unavailable tags. In this embodiment, the number increase process includes but is not limited to: data accumulation process or data multiplication process.

[0129] Data accumulation processing refers to performing an addition operation based on a preset accumulation value and the number of currently unavailable tags. It should be noted that those skilled in the art can flexibly set the preset accumulation value. For example, the preset accumulation value can be 1, and the number of unavailable tags is added by 1 each time the accumulation processing is performed; the preset accumulation value can also be 2, and the number of unavailable tags is added by 2 each time the accumulation processing is performed. Such specific adjustments and changes to the preset accumulation value do not deviate from the technical principles of the present invention and should be limited within the scope of protection of the present invention.

[0130] Data accumulation processing refers to multiplication operation based on the preset accumulation value and the number of currently unavailable tags. It should be noted that those skilled in the art can flexibly set the preset accumulation value. For example, the preset accumulation value can be 2, and the number of unavailable tags is multiplied by 2 each time the accumulation processing is performed; the preset accumulation value can also be 3, and the number of unavailable tags is multiplied by 3 each time the accumulation processing is performed. Such specific adjustment and change of the preset accumulation value does not deviate from the technical principle of the present invention and should be limited within the protection scope of the present invention.

[0131] Step 22: Determine whether the number of unavailable tags of the current vehicle charging facility is greater than or equal to the preset number threshold. If the number of unavailable tags is greater than or equal to the preset number threshold, the current vehicle charging facility is determined to be an unavailable vehicle charging facility during the relevant driving period (the driving period in the unavailable tag). If the number of unavailable tags is less than the preset number threshold, go to step S101 to continue to obtain the driving trajectory data of other vehicles for evaluation and analysis.

[0132] Furthermore, after evaluating that a certain vehicle charging facility is unavailable during a certain driving period, a comprehensive evaluation can be performed in combination with the evaluation results obtained based on the operating parameters of the vehicle charging facility, so as to more accurately evaluate the quality of the vehicle charging facility. Specifically, in one embodiment, Figure 1 The vehicle charging facility evaluation method shown may further include the following steps S105 to S106 after step S104.

[0133] Step S105: obtaining evaluation index values ​​corresponding to each vehicle energy charging facility respectively obtained in advance according to the operating parameters corresponding to each vehicle energy charging facility respectively.

[0134] Operation parameters refer to parameters that can characterize the operating status of vehicle charging facilities. Operation parameters include but are not limited to: charging speed, charging success rate, etc. of vehicle charging facilities. An example: If the vehicle charging facility is a charging pile, then the operating parameters of the charging pile may include charging speed, charging current, charging success rate, temperature, etc.

[0135] The evaluation index value refers to the specific value of the evaluation index evaluated based on the operating parameters of the vehicle energy replenishment facility. The evaluation index includes, but is not limited to, evaluation score, evaluation grade, etc. In this embodiment, a conventional evaluation method in the art can be used to evaluate the specific value of the corresponding evaluation index based on the operating parameters of the vehicle energy replenishment facility. For example: If the vehicle energy replenishment facility is a charging pile, the evaluation score of the charging pile can be determined based on the charging success rate of the charging pile. The higher the charging success rate, the higher the evaluation score, and the lower the charging success rate, the lower the evaluation score.

[0136] Step S106: Obtain the evaluation results (whether it is an unavailable vehicle energy replenishment facility) corresponding to each of the above-mentioned vehicle energy replenishment facilities obtained through steps S101 to S104, and adjust the corresponding evaluation index values ​​according to the evaluation results corresponding to each of the above-mentioned vehicle energy replenishment facilities to obtain the final evaluation index values ​​corresponding to each of the above-mentioned vehicle energy replenishment facilities.

[0137] For example, if the evaluation result of a vehicle charging facility is that the vehicle charging facility is an unavailable charging facility, then its evaluation index value is reduced. If the evaluation result of a vehicle charging facility is that the vehicle charging facility is not an unavailable charging facility, then its evaluation index value is not adjusted or is increased.

[0138] In one embodiment, Figure 1 The vehicle energy replenishment facility evaluation method shown can also output the recommendation information of the vehicle energy replenishment facility according to the evaluation result after evaluating that a certain vehicle energy replenishment facility is an unavailable energy replenishment facility in a certain driving period. Specifically, if a certain vehicle energy replenishment facility is evaluated to be an unavailable energy replenishment facility in a certain driving period, then when responding to the energy replenishment facility recommendation request, this vehicle energy replenishment facility is not recommended. In addition, unavailable reminder information can also be output (for example: the vehicle energy replenishment facility numbered ID1 is not available from 10:00:00 to 12:00:00). If a certain vehicle energy replenishment facility is evaluated to be not an unavailable vehicle energy replenishment facility, then when responding to the energy replenishment facility recommendation request, this vehicle energy replenishment facility can be recommended. Further, in one embodiment, after step S105-step S106, the recommendation information of the vehicle energy replenishment facility can be output according to the final evaluation index value evaluated in step S105-step S106. Specifically, if the final evaluation index value is greater than or equal to the preset index value, then when responding to a request for recommendation of a charging facility, the vehicle charging facility can be recommended; if the final evaluation index value is less than the preset index value, then when responding to a request for recommendation of a charging facility, the vehicle charging facility is not recommended. The specific value of the preset index value can be selected according to actual conditions, and such adjustment and change of the preset index value does not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0139] Through the above steps S101 to S104, it is possible to analyze whether the vehicle has passed through other vehicle charging facilities based on the driving trajectory data of the vehicle within a period of time before charging, and to evaluate whether these other vehicle charging facilities that the vehicle has passed through are unavailable vehicle charging facilities based on the analysis results, thereby overcoming the defect that the conventional vehicle charging facility evaluation method only evaluates the quality based on the operating parameters of the vehicle charging facility, and cannot evaluate whether the vehicle charging facility is unavailable due to other factors such as the closure of the place where the charging facility is located, the parking space to which the charging facility belongs is occupied, etc. In addition, through the implementation described in the above steps S105 to S106, the accuracy of the evaluation of the quality of the vehicle charging facility can be further improved.

[0140] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effects of the present invention, different steps do not have to be performed in such an order. They can be performed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present invention.

In one embodiment, the description of the specific implementation function can be referred to in step S104.

If it is evaluated that a certain vehicle energy replenishment facility is not an unavailable vehicle energy replenishment facility, then when responding to an energy replenishment facility recommendation request, this vehicle energy replenishment facility may be recommended.

[0147] In one embodiment, Figure 2 The vehicle energy replenishment facility evaluation device shown may also include a comprehensive evaluation module.
