Description

Technical Field

[0001] The present invention relates to the technical field of navigation, and particularly to a method for planning a charging path during vehicle driving, an electronic device, and a storage medium. Background Art

[0002] With the popularization of electric vehicles, when people drive electric vehicles for travel, there are situations where the comprehensive estimation of charging points, driving mileage, battery power, etc. is inaccurate, resulting in range anxiety for vehicle owners during driving. On the other hand, even if a charging point is specifically found, it often takes a long time to wait for charging when going to park and charge, and there is even a possibility that all charging piles are occupied.

[0003] The emergence of mobile charging vehicles has largely solved the above problems. Refer to Figure 1 , which shows a scenario of in - motion charging where a charging vehicle is connected to a vehicle to be charged, that is, a dedicated charging vehicle docks with the vehicle to be charged through a charging cable. The two vehicles achieve driving coordination through a signal conduction line bound to the charging cable harness, enabling the vehicle to be charged to obtain charging services during driving, which can effectively solve the above problems of range anxiety or charging waiting.

[0004] However, as an independent vehicle, the charging vehicle cannot avoid paying tolls when driving through toll roads; and the tolls for passing through toll roads by the charging vehicle need to be borne in whole or in part by the vehicle to be charged, which leads to an increase in charging costs and even a loss outweighing the gain. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defect in the prior art that the charging cost increases due to the charging vehicle being charged tolls, and to provide a method for planning a charging path during vehicle driving, an electronic device, and a storage medium.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] The present invention provides a method for planning a charging path during vehicle driving, where the charging path is the path traveled by the vehicle to be charged during the charging process by the charging vehicle. The charging path planning method includes:

[0008] Obtain the charging request of the vehicle to be charged;

[0009] Obtain toll road information;

[0010] Determine the charging path according to the charging request and the toll road information, so that the charging path does not include toll roads.

[0011] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, the above-mentioned charging path planning method during vehicle driving is implemented.

[0012] The present invention also provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the above-mentioned charging path planning method during vehicle driving is implemented.

[0013] The positive and progressive effects of the present invention are as follows: By providing a charging path planning method, an electronic device, and a storage medium during vehicle driving, a convenient and flexible charging service during driving can be obtained, the driving efficiency can be improved, and the anxiety of vehicle owners due to concerns about insufficient power can be eliminated; at the same time, by reasonably planning the navigation route, the road and bridge fees generated by the charging vehicle during the charging process can be effectively avoided, and the cost of charging during driving can be reduced.

[0020] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the described embodiments.

[0021] Embodiment 1

[0022] Referring to Figure 2 as shown, this embodiment specifically provides a charging path planning method during vehicle driving. Among them, the charging path is the path traveled by the vehicle to be charged during the charging process by the charging vehicle, and includes the following steps:

[0023] S1. Obtain the charging request of the vehicle to be charged;

[0024] S2. Obtain toll road information;

[0025] S3. Determine a charging route based on the charging request and the toll road information so that the charging route does not include toll roads.

[0026] In this embodiment, the vehicle to be charged is a vehicle with an electric drive function, such as a pure electric new energy vehicle or a hybrid electric vehicle. The charging vehicle is a vehicle that can provide a distribution-type mobile charging service for the above-mentioned vehicle with an electric drive function, usually a mobile tram charging device with a self-power supply system, and the degree of automation in the operation process is usually relatively high. The charging route in this embodiment is the route passed by the vehicle to be charged during the entire process of receiving charging from the charging vehicle. During this co-driving process, it can be determined according to actual needs whether the vehicle to be charged or the charging vehicle drives in the front, and there is no limitation.

[0027] Steps S1 and S2 respectively obtain the charging request of the vehicle to be charged and the toll road information. In one application scenario, the planning method of this embodiment can be responded to by a charging vehicle dispatch center or a similar command organization for the charging request of the vehicle to be charged.

[0028] Among them, the charging vehicle dispatch center coordinates and manages the charging vehicle through the charging server; receives the charging service request from the vehicle to be charged, and communicates with the navigation server to achieve dynamic path planning. The navigation server provides a preset static path planning and dynamic replanning for the in-travel charging service according to the information provided by the charging server; the vehicle to be charged sends a charging service request to the charging server; and accepts the static or dynamic path planning returned by the charging server. The charging vehicle provides in-travel charging service to the vehicle to be charged according to the dispatch of the charging server. As an optional connection method, the connection relationship between the above-mentioned charging vehicle, vehicle to be charged, navigation server, and the charging server of the charging vehicle dispatch center is as Figure 3 shown. The planning method of this embodiment can be implemented by the above-mentioned charging server. Those skilled in the art know that the above application scenario, execution entity, and each connection relationship including vehicles and servers are all for more conveniently describing the planning method of this embodiment, and do not constitute any limitation to the planning method. Those skilled in the art know that the execution entity of the planning method of this application is not limited to this, and as long as it has a navigation planning function and is communicatively connected to the above-mentioned charging vehicle and vehicle to be charged, a server or a similar device can execute this planning method, so it all falls within the protection scope of this application.

[0029] Specifically, the charging request of the vehicle to be charged can be sent to the dispatching center through the vehicle's wireless network module or communication module. The charging request may include the identifier information of the charging vehicle (such as the vehicle identification number), the current location information obtained by the positioning module, the current battery parameter, the current navigation path, and the destination, etc.

[0030] The purpose of step S3 to determine the charging path based on the charging request and the toll road information is to ensure that the charging path does not include toll roads. For the charging process of the charging vehicle and the vehicle to be charged, the section between the meeting point and the separation point is the charging path. Step S3 determines that if there is a situation where the meeting point to the separation point coincides with a toll road, including the meeting point or the separation point coinciding with the toll road, then the charging path includes the toll road. Of course, the above explanation of whether to include a toll road is not limited to the judgment of spatial location, but is determined by the inherent attribute of the toll road, that is, the generation of tolls.

[0031] Based on existing navigation technologies, several charging paths can be dynamically planned based on the position information of the vehicle to be charged, etc. This can be achieved based on path planning algorithms or by calling relevant interfaces of map service products. The planning method of this embodiment aims to screen different known candidate paths, and finally determine the one without toll roads as the charging path. Of course, after the charging path is determined, it can be sent to both the charging vehicle and the vehicle to be charged for docking charging preparation and itinerary prediction, etc.

[0032] Among them, the toll road information in step S2 can be real-time road toll information obtained from departments such as road administration and traffic management. Toll roads usually include toll bridges, highways, etc. However, as mentioned above, whether it will cause tolls for passing vehicles is the basis for judging whether a road is a toll road. Therefore, the entrances and exits of the above-mentioned toll bridges and highways do not limit the judgment of toll roads in this embodiment. For example, although not between the entrances and exits of highways or bridges, a road that will cause tolls when passing through it undoubtedly belongs to the category of toll roads in this embodiment. Taking some cross-provincial highways as an example, there is no exit on the section from the highway exit of one province (charging for the section of this province) to the highway entrance of another province (starting to charge for the section of this province), so passing through this section will inevitably drive into the highway entrance and be charged, so this section belongs to the toll road. Another example is that when some expressways are free on legal holidays, it can be considered that this expressway is a free road.

[0033] In a preferred embodiment, step S3 includes:

[0034] Obtain the current navigation path of the vehicle to be charged;

[0035] Determine whether there is a charging path in the current navigation path;

[0036] If it exists, determine the charging path from the current navigation path;

[0037] If it does not exist, re-plan the navigation path of the vehicle to be charged, and determine whether there is a charging path in the re-planned navigation path.

[0038] For the vehicle to be charged, it usually requests charging due to an urgent power shortage. The reason why the vehicle owner does not choose to find and stop at a fixed charging station nearby for charging, but requests mobile charging service during driving, also indicates the willingness to reach the destination as soon as possible. Preferably, in step S31, the current navigation path of the vehicle to be charged is obtained. When there is no charging path in the current navigation path, the navigation path of the vehicle to be charged is re-planned, and the judgment on whether there is a charging path is made again. Those skilled in the art can know that the navigation modes of vehicles usually include a recommended mode, a shortest path mode, a least charge mode, a highway priority mode, a no-highway mode, etc., so that different users can flexibly select according to their own needs. Among them, navigation path settings such as the no-highway mode and the least charge mode can avoid or partially avoid toll roads. And, "obtain the current navigation path of the vehicle to be charged → judge whether there is a charging path in it → re-obtain the current navigation path of the vehicle to be charged", and obtain one or more charging paths corresponding to different navigation paths in a cyclic manner for the user to select, or output a recommended charging path according to the automatic judgment result. Of course, at this time, the current navigation path of the vehicle is also correspondingly changed to the navigation path corresponding to this charging path. Planning the charging path based on the navigation path of the vehicle to be charged is beneficial to taking into account the charging demand and driving efficiency, conforms to the interests of the vehicle owner, and can better highlight the advantages of in-driving charging service.

[0039] In a preferred embodiment, the step of judging whether there is a charging path in the current navigation path includes:

[0040] Determine the meeting point of the vehicle to be charged and the charging vehicle, where the meeting point is located on the current navigation path;

[0041] Based on the meeting point, judge whether there is a charging path in the navigation path.

[0042] As described above, the starting point of the charging path is the meeting point of the charging vehicle and the vehicle to be charged. The meeting point is determined based on the current navigation path, that is, without changing the destination of the vehicle to be charged, the charging vehicle travels to the meeting point and starts charging the vehicle to be charged during driving. It can be understood that in this embodiment, for the convenience of describing the planning method itself, the specific docking operation after the two vehicles meet is not elaborated. And the meeting point is determined. In the application scenarios exemplified above, it can also be planned and allocated by the dispatch center according to the position of the vehicle to be charged, the expected vehicle speed (such as obtained by combining the section speed limit and real-time congestion data, etc.) and the charging vehicle data (such as the current position distribution of the charging vehicle, the empty vehicle / heavy vehicle situation), determine the charging vehicle for providing charging services, and then combine the current position of the charging vehicle and the current navigation path of the vehicle to be charged to determine the meeting point, and then judge whether there is a charging path in the navigation path based on the meeting point, and convert the judgment based on the toll road and the charging path into a judgment based on the toll road and the meeting point. The meeting point obtained based on the current navigation path of the vehicle to be charged and the designated charging vehicle is determined. Of course, the planning method of this embodiment can also be used in scenarios where there are multiple charging vehicles available for dispatch, such as executing this planning method for multiple charging vehicles; or preferably selecting one charging vehicle from multiple charging vehicles to execute the planning method of this embodiment.

[0043] In an alternative embodiment, the step of determining whether there is a charging path in the navigation path based on the meeting point specifically includes: determining whether the meeting point is located on a toll road. If the determination result is yes, there is no charging path in the navigation path.

[0044] The basis for this determination is that if there is a toll road in the current navigation path and the determined meeting point falls on the toll road, it can directly indicate that the charging vehicle will have to pay the fees required for the corresponding section, that is, it does not conform to the charging path to be selected by the planning method of this embodiment. Therefore, there is no charging path as required in the current navigation path.

[0045] In an alternative embodiment, the above step of determining whether there is a charging path in the navigation path based on the meeting point can be determined as follows: if the toll road entrance is included between the current position of the vehicle to be charged and the meeting point, the meeting point is located on the toll road.

[0046] Specifically, the toll road entrance can be the entrance of a highway, the entrance of a toll bridge or tunnel, etc. Since the vehicle to be charged must pass through the above toll road entrance and then travel to the meeting point in order to reach the meeting point, it will necessarily pass through this toll road. Therefore, it is determined that the meeting point is located on the toll road in this case. See Figure 4, showing a schematic diagram of the scenario of the first charging path planning process. For example, there are a vehicle to be charged A and a charging vehicle B. The vehicle to be charged A will meet the charging vehicle B at the meeting point T1 according to the originally planned navigation path L1. Since there is a highway toll station (entrance) 1 between the meeting point T1 and the vehicle to be charged A, the meeting point T1 is located in the toll section. At this time, the navigation path L2 obtained by re - performing dynamic planning avoids the above - mentioned toll station 1, so that the meeting point T2 is no longer behind the toll station entrance, that is, the charging vehicle B does not need to pass through the toll section during the process of traveling to the meeting point T2. Of course, the navigation path L2 should also enable the charging vehicle to leave at the exit before the next highway toll station (entrance) 2 after the final separation point T3.

[0047] In a preferred embodiment, the step of judging whether there is a charging path in the navigation path based on the meeting point specifically includes:

[0048] Based on the meeting point, obtain the separation point of the charging vehicle and the vehicle to be charged;

[0049] If the separation point is located in the toll section, or there is no exit between the separation point and the nearest toll section entrance along the forward direction, there is no charging path in the current navigation path.

[0050] In this embodiment, further obtain the separation point of the charging vehicle and the vehicle to be charged based on the meeting point, so as to judge whether the charging vehicle will pass through the toll section according to the situation of the separation point.

[0051] In the first case, when the separation point is located in the toll section, it undoubtedly indicates that the charging vehicle and the vehicle to be charged have passed through the toll section before separation. Therefore, there is no charging path in the current navigation path at this time. Preferably, the following method can be used to judge whether the separation point is located in the toll section:

[0052] If only the toll section entrance is included between the current position and the separation point, the separation point is located in the toll section. Here, the current position is the position where the vehicle to be charged is located when judging the existence of the toll section, and it is located on the current navigation path. If only the toll section entrance, such as a highway toll station entrance, is included between the current position and the separation point, it can indicate that the charging vehicle will surely generate toll fees. On the contrary, if only the exit of the highway toll station exists between the current position and the separation point, or both the entrance and exit of the highway toll station exist at the same time; it is not sufficient to consider that the charging vehicle will generate toll fees. The reason is that the meeting point may be behind the exit of the highway toll station at this time. Of course, it can also be judged whether the separation point is located between the corresponding highway toll station entrance and exit. If so, the separation point is located in the toll section.

[0053] In the second case, in the forward direction of the current navigation path, if there is no road exit between the separation point and the entrance of the nearest toll road section that allows the vehicle to be charged to drive away, it also means that the road between the separation point and the entrance of the toll road section will inevitably incur tolls for the charging vehicle. Therefore, it can be determined that there is no charging path in the current navigation path.

[0054] See Figure 5 , which shows a schematic diagram of the second scenario of this embodiment. For example, the vehicle A to be charged merges with the charging vehicle B at the convergence point T1 in the forward direction of the navigation path L1 and separates at the separation point T2. When the charging vehicle B reaches the separation point T2, there is no exit between it and the nearest highway toll station entrance ahead. In other words, the charging vehicle B has missed the last chance to drive away from the toll road section. Therefore, there is no charging path in L1. In the separately planned charging path L2, the two vehicles merge at T3 and separate at T4. After the charging is completed, since the charging vehicle B can drive away from the nearby intersection, there is no need to incur tolls. Therefore, L2 is a charging path that meets the requirements. Of course, at this time, the navigation path of the vehicle A to be charged has also changed, but the destination has not changed. Thus, the driving efficiency and charging requirements of the vehicle to be charged are taken into account.

[0055] In a preferred embodiment, the step of obtaining the separation points of the charging vehicle and the vehicle to be charged based on the convergence point includes:

[0056] Determine the target charging time according to the charging request;

[0057] Obtain the necessary charging distance according to the target charging time and the estimated vehicle speed;

[0058] Determine the separation point based on the convergence point and the necessary charging distance.

[0059] Currently, when the charging vehicle charges the vehicle to be charged, it usually takes 30 minutes of rapid charging to fully charge 80% of the battery. Accordingly, for example, if the 80% battery level target is the default or recommended charging request, the target charging time can be set to 30 minutes. Since the vehicle to be charged is in the driving process, by combining its estimated vehicle speed during the charging process, the necessary charging distance for the entire charging process can be determined. For example, the necessary charging distance can be obtained by multiplying the target charging time and the estimated vehicle speed.

[0060] Preferably, before obtaining the necessary charging distance based on the target charging time and the estimated vehicle speed, the estimated vehicle speed can also be obtained first. For example, the estimated vehicle speed can be determined according to the speed limits of the sections along the current navigation route, including determining the estimated vehicle speed by combining the upper and lower speed limits of the lanes. In another alternative implementation, the estimated vehicle speed can be determined according to the average vehicle speed of the vehicle to be charged within a preset journey. For example, the corresponding estimated vehicle speed is determined by obtaining the average vehicle speed of the vehicle to be charged within a representative journey for vehicle speed prediction that has already been traveled. The preset journey can be selected from sections with strong representativeness and can be obtained based on previous statistical experience data.

[0061] Taking the two scenarios exemplified above as an example, the determination process of the necessary charging distance is explained.

[0062] In the first charging path planning process described above, when the convergence point T1 is located just after the highway toll booth, only the navigation path needs to be re-obtained, and it is sufficient that the length of the charging path L2 > the necessary charging distance = the estimated speed V during driving * 0.5 hours.

[0063] In the second charging path planning process described above, the convergence point T1 is on the navigation path set for the vehicle to be charged and is located before the highway toll booth. Then, by obtaining the necessary charging distance = the estimated speed V during driving * 0.5 hours and combining the convergence point T1, the position of the estimated separation point T2 can be obtained. Since there is no exit after T2, the charging vehicle will drive through the toll section. At this time, the charging server performs dynamic path planning to re-determine a charging path that meets the requirements, such as the charging path L2.

[0064] This embodiment provides a method for planning a charging path during vehicle driving, which enables the advantages of charging during driving to be maintained while effectively avoiding the road and bridge fees of the charging vehicle and reducing the cost of charging during driving by reasonably planning the navigation route.
