Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

It should be noted that the terms "including" and "having" in the embodiments of the present invention and the drawings and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes unlisted steps or units, or optionally also includes Other steps or units inherent to these processes, methods, products or equipment.

The embodiment of the invention discloses a method for recommending a driving route of a vehicle, which can automatically recommend a driving route including a charging pile for a user, so that the user can find the charging pile more easily. Detailed descriptions are given below.

Example one

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a method for recommending a vehicle driving route disclosed in an embodiment of the present invention. Wherein, the method for recommending the driving route of the vehicle shown in FIG. 1 is applicable to in-vehicle electronic equipment such as vehicle central control equipment and on-board computer, which is not limited in the embodiment of the present invention. As shown in Fig. 1, the method for recommending the driving route of the vehicle may include the following steps:

101. The recommendation system generates an initial driving route according to the user's route demand information.

In the embodiment of the present invention, the user's route demand information may include information such as the starting point of the driving route, the driving destination, the stopping point, the route preference, and the charging demand. Among them, the starting point of the driving route can be the current position of the vehicle determined by the navigation system of the vehicle, or it can be input by the user; the route preference can be specific options such as high speed priority, cost priority, or time priority; charging requirements are used to indicate the user Do you need to charge the vehicle while driving?

It is understandable that the recommendation system can specifically use the current position of the vehicle as a starting point and the aforementioned driving destination as an end point to generate an initial driving route passing through the aforementioned stopping point. If the current location of the vehicle is taken as the starting point, the above driving destination is the ending point, and there is more than one route passing through the above stopping point, the recommendation system can select one of the multiple routes as the initial driving according to the route preference input by the user route. In addition, the recommendation system can also verify the driving destination before generating the initial driving route. Specifically, it can be verified whether the driving destination is true and unique, whether the driving destination is more than the preset first distance threshold (too far) from the current position of the vehicle, or whether the driving destination distance is lower than the preset second distance threshold (Too close). If the driving destination is true, unique, and the current distance from the vehicle is lower than the first distance threshold and higher than the second distance threshold, the verification of the driving destination is passed, and an initial driving route to the driving destination is generated.

Further, before generating the initial driving route, the recommendation system can further verify the stopover points, route preferences, and charging requirements input by the user. Specifically, it can be verified whether the stopover point is true and unique, whether the distance required to detour through the stopover point exceeds the third distance threshold (whether the detour is serious); and whether the route preference requirements entered by the user are clear, such as Whether the route preference demand input by the user is any of the options of high speed priority, cost priority, time priority, etc., if so, it can be considered that the route preference demand input by the user is clear; and check whether the charging demand input by the user is reasonable, for example Check whether there is a charging pile within the reach of the current cruising range of the vehicle. If so, it can be considered that the charging demand input by the user is reasonable.

102. The recommendation system searches for charging piles within the range of the initial driving route as candidate charging piles.

In the embodiment of the present invention, the range along the initial travel route is an area formed by the normal of each point on the initial travel path, and the normal length of each point is the same. The normal length can be set to a relatively short distance, such as 5 kilometers, to facilitate the vehicle to reach the charging pile within a short distance. Please also refer to FIG. 2. FIG. 2 is a schematic diagram of the distribution of charging piles along the initial driving route according to an embodiment of the present invention. As shown in Figure 2, taking the normal length of 5 kilometers as an example, when the vehicle is driving on the initial driving route, the distance between the charging piles and the vehicle along the way is all within 5 kilometers. As shown in Figure 2, the charging piles in the range along the way are the charging piles within the range, and these charging piles can be used as alternative charging piles. The charging piles outside the range along the way are charging piles that do not meet the range. When the following step 203 is executed to generate a recommended driving route, these charging piles that do not meet the range are not considered.

As an optional implementation manner, if the stop point input by the user is received when the initial driving route is generated in step 101, the recommendation system may specifically select the charging piles within the range of the initial driving route when step 102 is performed. The charging piles located on the road section between the current position of the vehicle and the stopping point are selected as candidate charging piles. In the implementation of the above-mentioned embodiments, the power supplement when the vehicle travels from the current position to the stopping point can be considered first to reduce the number of alternative charging piles, thereby reducing the amount of calculation required when generating recommended driving routes and improving the feedback of the recommendation system speed.

103. The recommendation system uses the location of the alternative charging pile as a stopping point to adjust the initial driving route to generate a recommended driving route.

In this embodiment of the present invention, as an optional implementation manner, the way in which the recommendation system executes step 103 may specifically be:

When there are at least two candidate charging piles, for each candidate charging pile, the recommendation system generates a recommended driving route passing through the candidate charging pile and corresponding to the candidate charging pile by adjusting the initial driving route to obtain the Recommended driving route with the same number of alternative charging piles. In other words, for each candidate charging pile, a corresponding recommended driving route is generated.

It is understandable that if there is only one alternative charging pile, correspondingly, there is only one recommended driving route corresponding to the alternative charging pile.

Please refer to Figure 3-1 and Figure 3-2 together. Figure 3-1 is an example diagram of an initial driving route disclosed in an embodiment of the present invention; Figure 3-2 is a recommended driving route disclosed in an embodiment of the present invention Example graph. In Figure 3-1 and Figure 3-2, the origin A is the current location of the vehicle, the destination B is the destination of the vehicle, and the stopping point C is the stopping point entered by the user. As shown in Figure 3-1, two alternative charging piles are searched for along the initial driving route. Assuming that a corresponding recommended driving route is generated for each alternative charging pile, the two recommended driving routes finally generated are as follows: As shown in Figure 3-2.

As another optional implementation manner, the way in which the recommendation system executes step 103 may also be specifically:

When there are at least two alternative charging piles, select from the at least two alternative charging piles every charging pile with an interval greater than or equal to the recommended mileage of the vehicle, and set the aforementioned interval greater than or equal to the recommended mileage. The charging piles with mileage are used as different stopping points on the same driving route to adjust the initial driving route to generate a recommended driving route passing through multiple alternative charging piles. Wherein, the aforementioned recommended mileage may be the average mileage that the vehicle can travel between two charges.

104. The recommendation system outputs a recommended driving route.

In the embodiment of the present invention, it is assumed that the recommendation system generates at least two recommended driving routes. As an optional implementation manner, the recommendation system may output all the generated recommended driving routes. As another optional implementation manner, the recommendation system may also filter out one recommended driving route from at least two recommended driving routes, and output the filtered recommended driving route.

It can be seen that in the method described in Figure 1, after the recommendation system generates the initial driving route, it can search for alternative charging piles near the initial driving route, and use the alternative charging piles as stops to adjust the initial driving route to generate and The recommended driving route through alternative charging piles is output, so that users can find the charging piles more easily. In addition, in the process of generating the recommended driving route, the user does not need to manually select a suitable charging pile, which is more convenient and faster.

Example two

Please refer to FIG. 4, which is a schematic flowchart of another method for recommending a driving route of a vehicle disclosed in an embodiment of the present invention. As shown in Fig. 4, the method for recommending the driving route of the vehicle may include the following steps:

201. The recommendation system checks whether there are charging piles within the reach of the vehicle based on the current location of the vehicle and the current cruising range of the vehicle; if yes, go to step 202; if not, end this process.

In the embodiment of the present invention, the current cruising range of the vehicle refers to the mileage that the vehicle can continue to travel before the power consumption reaches a certain power threshold. In addition, the distance between any place within the reach of the vehicle and the current position of the vehicle is less than the current cruising range of the vehicle. Specifically, the specific method of checking whether there is a charging pile within the reach of the vehicle may be: searching for the charging pile closest to the current position of the vehicle, and judging whether the distance between the nearest charging pile and the current position of the vehicle is less than It is equal to the current cruising range of the vehicle; if it is, there are charging piles within the reach of the vehicle; if not, there is no charging pile within the reach of the vehicle.

By verifying whether there is a charging pile within the reach of the vehicle, it is verified whether the charging demand input by the user is reasonable. When it is verified that there is no charging pile within the reach of the vehicle, it is difficult to find the charging pile after the vehicle is driven out, the risk of the vehicle being exhausted is high, and the charging demand is unreasonable. Therefore, at the end of this process, it is not recommended that the user drive the vehicle out, which can reduce the possibility of the vehicle stopping halfway due to difficulty in charging.

202. The recommendation system generates an initial driving route according to the user's route demand information.

203. The recommendation system searches for charging piles within the range of the initial driving route.

204. Based on the current location of the vehicle and the current cruising range of the vehicle, the recommendation system filters out the charging piles reachable by the vehicle from the charging piles within the range of the initial driving route as candidate charging piles.

In the embodiment of the present invention, when the distance between the driving destination and the current position of the vehicle exceeds the cruising range when the vehicle is driven out, there may be part of the charging piles found by the recommendation system within the range of the initial driving route. The charging pile is inaccessible to vehicles. Therefore, the charging piles that cannot be reached by these vehicles can be screened out first. Please also refer to FIG. 5. FIG. 5 is an example diagram of screening charging piles according to the cruising range of a vehicle according to an embodiment of the present invention. As shown in Figure 5, the area within the arc indicated by the cruising radius is the reach of the vehicle.

By screening the charging piles reachable by the vehicle, it is possible to reduce the interference of remote charging piles far from the current position of the vehicle to the final recommended driving route, reduce the possibility of serious detours on this route, and improve the recommended system to choose charging piles Reasonableness.

205. The recommendation system uses the location of the alternative charging pile as a stopping point to adjust the initial driving route to generate a recommended driving route.

When there are at least two candidate charging piles, for each candidate charging pile, the recommendation system generates a recommended driving route passing through the candidate charging pile and corresponding to the candidate charging pile by adjusting the initial driving route to obtain the Recommended driving route with the same number of alternative charging piles.

206. The recommendation system outputs the route with the shortest total mileage, the shortest total time, and/or the least total road cost among the recommended driving routes.

In the embodiment of the present invention, when step 205 is executed to generate at least two recommended driving routes, the best route is selected from the at least two recommended driving routes, and the best route is output. Among them, the best route may be the recommended driving route with the shortest total mileage, or the recommended driving route with the shortest total time, or the recommended driving route with the least total toll. Optionally, only any one of the above-mentioned three best routes may be output, any two of the best routes or all of the above-mentioned three best routes may be output, which is not limited in the embodiment of the present invention.

Please refer to FIG. 6 together. FIG. 6 is an example diagram of implementation of some steps in the method for recommending a driving route of a vehicle shown in FIG. 4. Fig. 6 shows an implementation example of steps 202 to 206 described above. It can be seen from Fig. 6 that the recommendation system can finally recommend a vehicle driving route starting from the current position of the vehicle and finally reaching the driving destination, passing the charging pile and the stopping point input by the user. In addition, the recommendation system can ensure that the vehicle will not be unable to reach the charging pile due to the cruising range, which can effectively alleviate the user's mileage anxiety.

It can be seen that in the method described in FIG. 4, the recommendation system can automatically generate a driving route passing the charging pile, so as to facilitate the user to find the charging pile for charging. Further, it is possible to check whether there are charging piles within the reach of the vehicle before generating the driving route, so as to reduce the situation that the remaining power cannot support the vehicle to drive to the charging pile, and reduce the possibility of the vehicle stopping halfway due to difficulty in charging. Furthermore, after searching for the charging piles within the range of the initial driving route, the charging piles reachable by the vehicle are selected as alternative charging piles, so as to reduce the interference of remote charging piles on the final recommended driving route. The possibility of serious detours in the route improves the rationality of the recommended system for selecting charging piles. In addition, in the method described in FIG. 4, the recommendation system can select the best driving route from a plurality of recommended driving routes, thereby saving the user driving mileage, driving time or road crossing expenses.

Example three

Please refer to FIG. 7, which is a schematic flowchart of another method for recommending a driving route of a vehicle disclosed in an embodiment of the present invention. As shown in Figure 7, the method for recommending the driving route of the vehicle may include the following steps:

301. The recommendation system checks the request parameters to determine whether the request parameters are abnormal; if so, return an abnormal result and end the process; if not, go to step 302.

In the embodiment of the present invention, the request parameter is generated when the user initiates a navigation request. The verification of request parameters can specifically include: 1. Verify whether the driving destination is true, unique, and whether the driving destination is too far or too far; 2. Verify whether the stopping point entered by the user is true, unique, and Whether the stop detour is serious; 3. Verify that the route preference requirements entered by the user are clear; 4. Verify that the route preference requirements entered by the user are clear; 5. Verify whether there are charging piles within the reach of the vehicle. When any of the above request parameters fails the verification, the request parameter is abnormal.

302. The recommendation system retrieves whether there is an initial driving route that meets the route requirement information; if so, execute step 303; if not, return an abnormal result and end this process.

In the embodiment of the present invention, the initial travel route that satisfies the route requirement information refers to a route that takes the current position of the vehicle as a starting point and the user's travel destination as an end point, and passes through a stop point input by the user. 303. The recommendation system retrieves whether there are charging piles within the range of the initial driving route; if yes, execute step 304; if not, return an abnormal result and end this process.

304. The recommendation system searches for charging piles within the range of the initial driving route to obtain a list of charging piles.

305. Based on the current location of the vehicle and the current cruising range of the vehicle, the recommendation system filters out the charging piles reachable by the vehicle from the charging pile list as candidate charging piles.

In the embodiment of the present invention, as an optional real-time method, the recommendation system can also target each charging pile in the charging pile list according to the historical number of times the vehicle has been charged in the charging pile and the current remaining idle time of the charging pile. The number of charging positions, the average user evaluation score of the charging pile, and the charging unit price of the charging pile are evaluated for each charging pile. For a certain charging pile, the higher the number of times the vehicle has been charged in the charging pile, the higher the evaluation score of the charging pile; the more the remaining idle charging positions of the charging pile, the higher the evaluation score of the charging pile ; The higher the average user evaluation score of the charging pile, the higher the evaluation score of the charging pile; the lower the charging unit price of the charging pile, the higher the evaluation score of the charging pile. After evaluating the charging piles based on the above four factors, the charging piles that can be reached by the vehicle and whose evaluation score is higher than a certain score threshold are selected from the charging pile list as candidate charging piles.

306. For each candidate charging pile, the recommendation system adds the candidate charging pile as a stopping point to adjust the initial driving route, so as to obtain a recommended driving route corresponding to each candidate charging pile.

307. The recommendation system screens out the best route from the recommended driving route, and outputs the best route.

In the embodiment of the present invention, the optimal route may be any one of the recommended driving routes with the shortest total mileage, the shortest total time, and the least total toll. Optionally, if the user inputs a route preference requirement, the recommended driving route corresponding to the route preference requirement input by the user is taken as the best route.

In addition, as an optional implementation manner, in the embodiment of the present invention, when the vehicle is driving according to the recommended driving route output by the recommendation system, if it is detected that the vehicle is charged with an alternative charging pile, the current range of the vehicle can be judged Whether the mileage is less than the distance between the current position of the vehicle and the driving destination; if less, update the next alternative charging pile according to the current position of the vehicle and the current cruising range of the vehicle; use the updated next alternative charging pile pair The recommended driving route is updated.

When the vehicle travels a long distance, only one charge may not support the vehicle to reach the driving destination. Therefore, two or more recharges need to be considered. With the implementation of the above-mentioned embodiments, after the vehicle completes one charge, the alternative charging pile used for the next charge can be updated according to the real-time current position of the vehicle and the cruising range, and the corresponding recommended driving route can be further updated.

It can be seen that in the method described in FIG. 7, the recommendation system can automatically recommend a driving route through the charging pile for the user, and the user can easily reach the recommended charging pile, and the distance to be detoured is relatively short. Furthermore, after the vehicle has completed a charge, the alternative charging pile used for the next charge can be updated according to the current location of the vehicle and the cruising range, and the corresponding recommended driving route can be further updated, so as to satisfy the vehicle’s long-distance Two or more charging needs that may occur while driving.

Example four

Please refer to FIG. 8. FIG. 8 is a schematic structural diagram of a vehicle driving route recommendation system disclosed in an embodiment of the present invention. As shown in Fig. 8, the recommendation system of the vehicle driving route may include:

In the embodiment of the present invention, as an optional real-time manner, the search unit 802 can filter out the charging piles located in the section between the current position of the vehicle and the stopping point from the charging piles along the initial driving route as Alternative charging piles to reduce the number of alternative charging piles, thereby reducing the amount of calculation required when generating recommended driving routes and increasing the feedback speed of the recommendation system;

The second generating unit 803 is used to adjust the initial driving route by using the position of the alternative charging pile as a stopping point to generate a recommended driving route;

In the embodiment of the present invention, as an optional implementation manner, the second generating unit 803 may, when there are at least two alternative charging posts, for each alternative charging post, by adjusting the initial driving route, generate the Alternative charging piles and the recommended driving route corresponding to the alternative charging piles to obtain the same recommended driving route as the number of alternative charging piles;

As another optional implementation manner, the second generating unit 803 may also select from the at least two candidate charging piles when there are at least two candidate charging piles, and the interval between every two charging piles is greater than or equal to For the charging piles with the recommended driving range of the vehicle, the charging piles with the above-mentioned interval greater than or equal to the recommended driving range are used as different stopping points on the same driving route to adjust the initial driving route to generate recommendations for multiple alternative charging piles passing through Driving route. Among them, the above-mentioned recommended mileage may be the average mileage that the vehicle can travel between two charges;

The output unit 804 is used to output the recommended driving route.

In the embodiment of the present invention, the output unit 804 may specifically output all recommended driving routes generated by the second generating unit 803, or may filter out one recommended driving route from at least two recommended driving routes, and output the filtered recommended driving route , The embodiment of the present invention sets no limitation.

In addition, in the process of generating the recommended driving route, the user does not need to manually select a suitable charging pile, which is more convenient and faster.

Example five

Please refer to FIG. 9, which is a schematic structural diagram of another vehicle driving route recommendation system disclosed in an embodiment of the present invention. Among them, the recommendation system of the vehicle travel route shown in FIG. 9 is obtained by optimizing the recommendation system of the vehicle travel route shown in FIG. 8 as shown in FIG. 9. As shown in FIG. 9, the above-mentioned searching unit 802 may specifically include:

The search subunit 8021 is used to search for charging piles within the range of the initial driving route;
