Description

Technical Field

[0001] This invention belongs to the field of electric vehicle charging navigation, and particularly relates to a reminder method, system, medium and electronic device for vehicle charging navigation. Background Technology

[0002] Currently, when the battery level is low in new energy vehicles, a warning light illuminates on the dashboard to remind the driver to charge. Drivers check the remaining battery level and driving range on the dashboard and use navigation to find a suitable charging station. Under normal circumstances, this method meets the needs of most drivers. However, in special situations, such as when driving on highways, where charging is only available at highway service areas, the remaining battery level and driving range may not be sufficient to reach the service area. Even if the vehicle manages to reach the service area, if there are no available charging stations or the charging stations are unavailable, it will severely impact the driving experience. Summary of the Invention

[0003] To address the aforementioned issues, the present invention aims to provide a vehicle charging navigation reminder method, system, medium, and electronic device that can analyze the usage status of the vehicle battery and provide accurate battery level reminders and charging strategies to the driver, as well as monitor the operation of charging stations in service areas. This reduces charging anxiety for the driver, lowers the probability of traffic accidents, and enhances the user experience for long-distance travel of new energy vehicle owners.

[0004] A first aspect of the present invention provides a method for providing reminders for vehicle charging navigation, comprising:

[0005] Determine whether the vehicle is currently traveling on a long distance;

[0006] During long-distance driving, the actual driving range of the vehicle is calculated based on the target vehicle's historical travel data, current driving data, and displayed driving range.

[0007] A charging strategy is formulated based on the actual driving range, a charging strategy is selected to be sent to the driver, and a charging navigation route is determined based on the driver's feedback on the sent charging strategy.

[0008] Based on the determined charging navigation route, a prompt is sent to the driver to control the charging navigation route of the target vehicle.

[0009] Optionally, calculating the vehicle's actual driving range during long-distance driving, based on the target vehicle's historical trip data, current driving data, and displayed driving range, includes:

[0010] Obtain historical mileage data of the target vehicle that is pre-stored in the cloud; by analyzing the historical mileage data of the target vehicle, obtain the uncontrollable factors that affect the range, including actual mileage, theoretical range consumed, battery capacity and battery degradation rate;

[0011] The battery capacity and battery degradation rate of the historical driving data are matched with the current driving data to determine if there is similar data in the current driving data. If so, similar historical driving data is obtained to calculate the actual driving range of the target vehicle. Otherwise, historical driving data of the same model as the target vehicle, which is pre-stored in the cloud, is read and matched with the current driving data based on the battery capacity and battery degradation rate of the historical driving data of the same model as the target vehicle. When the number of matching operations reaches a preset threshold, the actual driving range of the target vehicle is calculated based on the historical driving data of the same model as the target vehicle.

[0012] The displayed range is adjusted based on the actual range of the target vehicle.

[0013] Optionally, the step of formulating a charging strategy based on the actual driving range includes: dynamically calculating the charging time and charging pile location based on the actual driving range, as well as the number and availability of charging piles in service areas and non-service areas, and determining the target charging pile location with the goal of minimizing the charging time.

[0014] Develop the preferred and alternative navigation routes to reach the target charging station location;

[0015] The preferred navigation route is the navigation route to the location of the target charging station in the service area;

[0016] The alternative navigation routes are navigation routes to the location of the target charging station outside the service area.

[0017] Optionally, the selected charging strategy sent to the driver's side includes:

[0018] Based on the preferred navigation route, determine the navigation destination during the trip;

[0019] Based on the queuing status or equipment malfunction at the navigation destination, alternative navigation routes are sent to the driver.

[0020] Optionally, determining the charging navigation route based on the driver's feedback on the sent charging strategy includes: obtaining feedback messages from the driver regarding the preferred or alternative navigation routes; and determining the charging navigation route by reading the driver's acceptance of the navigation destination in the sent charging strategy contained in the feedback messages.

[0021] Optionally, the step of sending a prompt to the driver based on the determined charging navigation route and controlling the charging navigation route of the target vehicle includes:

[0022] Send a confirmed charging navigation route to the driver's side;

[0023] When the driver adds the navigation destination to the navigation waypoint in the determined charging navigation route, the charging navigation route of the target vehicle is controlled; and when the driver deletes the waypoint based on changes in the actual situation, the target vehicle continues to navigate according to the charging navigation route until the trip ends or the driver actively turns off the charging transmission service, at which point the navigation route prompt is turned off.

[0024] Optionally, the method further includes: after navigation ends, uploading the trip data to the cloud for use in subsequent trips.

[0025] In a second aspect, the present invention provides a vehicle charging navigation reminder system for implementing the vehicle charging navigation reminder method described in any one of the first aspects, the system comprising:

[0026] The judgment module is used to determine whether the vehicle is currently in a long-distance driving state;

[0027] The driving range calculation module is used to calculate the actual driving range of the vehicle during long-distance driving based on the target vehicle's historical travel data, current driving data, and displayed driving range.

[0028] The charging navigation module is used to formulate a charging strategy based on the actual driving range; select a charging strategy to send to the driver; and determine a charging navigation route based on the driver's feedback on the sent charging strategy.

[0029] The charging reminder module is used to send reminders to the driver based on a determined charging navigation route, and to control the charging navigation route of the target vehicle.

[0030] Thirdly, the present invention provides a computer-readable storage medium having a computer program stored thereon, characterized in that the program, when executed by a processor, implements the method steps as described in any one of the first aspects.

[0031] Fourthly, the present invention provides an electronic device, including a memory and a processor, characterized in that the memory stores a computer program, which, when executed by the processor, causes the processor to perform the method steps as described in any one of the first aspects.

[0032] Compared with the closest existing technology, the present invention has the following advantages:

[0033] This invention proposes a vehicle charging navigation reminder method, system, medium, and electronic device, including determining whether the vehicle is currently on a long-distance journey; calculating the vehicle's actual range based on historical travel data, current driving data, and displayed range during long-distance travel; and formulating a charging strategy based on the actual range. The above comprehensively considers the vehicle's battery range in different driving sections, analyzes the battery's usage status, calculates the actual range, and provides accurate battery level reminders and charging strategies to the driver; it also monitors the operation of charging stations in service areas to ensure smooth charging upon arrival, providing charging assurance for drivers, reducing charging anxiety, and improving the user experience for new energy vehicle owners on long-distance trips.

[0034] Furthermore, after sending the charging strategy to the driver, the system can determine the final charging navigation route based on the driver's feedback on the sent charging strategy; based on the determined charging navigation route, it can send prompts to the driver to control the charging navigation route of the target vehicle; this solves the problem that when the vehicle's battery is low, the driver cannot know the comparison between the remaining range and the distance to the next available charging service area from the battery power and range display, and cannot determine whether the vehicle can make it to the service area; or even if the vehicle can drive to the service area normally, it is impossible to confirm whether the vehicle can make it to a charging station or whether the charging station is working properly, thus reducing the probability of accidents.

[0040] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore merely examples, and should not be construed as limiting the scope of protection of the present invention.

[0041] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0042] This invention provides a vehicle charging navigation reminder method, system, medium, and electronic device, and details the related improvements of this invention through the following aspects:

[0043] The system retrieves the vehicle's historical driving data from the cloud, including actual mileage, theoretical driving range consumed, average battery capacity, average battery degradation rate, and other key factors affecting driving range.

[0044] Based on historical driving data, current battery capacity and battery degradation rate, and remaining driving range, the closest approximation of the actual driving range is calculated.

[0045] Based on historical driving data of battery capacity and degradation rate, the system matches the current state to the closest known condition. If no similar data exists in the historical driving data, the estimated range is calculated by discounting the displayed range. A conservative discount rate is used to prevent users from running out of battery and being stranded on the highway waiting for roadside assistance. Historical data uploaded by other car owners can also be used as a basis for calculation. In short, the more historical driving data available, the easier it is to find the optimal discount rate, the more accurate the algorithm will be, and the closer the calculated range will be to the actual driving range.

[0046] Based on the calculated actual driving range, charging stations at service areas along the route will be prioritized. If there are queues or damage at the charging stations at the service areas, charging stations outside the service areas will be sent for the driver to decide whether to accept.

[0047] If the driver agrees to the sent charging location, this location will be added to the navigation waypoints without needing to stop navigation to find a charging location, ensuring the continuity of the journey. Navigation will resume once the sending point is reached, navigation will pause, and charging will complete. If circumstances change and the driver no longer wishes to charge, the waypoint can be deleted, and navigation can continue.

[0048] This notification will not be sent again until the trip ends or the driver actively turns off the charging notification, to avoid disturbing the driver. After navigation ends, the driving data will be uploaded to the cloud for future use.

[0049] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0050] In one embodiment, such as Figure 1 As shown, a method for providing reminders for vehicle charging navigation is provided. The specific steps of the method include:

[0051] S101 determines whether the vehicle is currently in a long-distance driving state;

[0052] During long-distance driving, S102 calculates the vehicle's actual driving range based on the target vehicle's historical mileage data, current driving data, and displayed driving range.

[0053] S103 formulates a charging strategy based on the actual driving range, selects a charging strategy to send to the driver, and determines a charging navigation route based on the driver's feedback on the sent charging strategy.

[0054] Based on the determined charging navigation route, S104 sends a prompt to the driver and controls the charging navigation route of the target vehicle.

[0055] In the above embodiment, step S102, during long-distance driving, calculates the vehicle's actual driving range based on the target vehicle's historical mileage data, current driving data, and displayed driving range, including:

[0056] Obtain historical mileage data of the target vehicle that is pre-stored in the cloud; by analyzing the historical mileage data of the target vehicle, obtain the uncontrollable factors that affect the range, including actual mileage, theoretical range consumed, battery capacity and battery degradation rate;

[0057] The battery capacity and battery degradation rate of the historical driving data are matched with the current driving data to determine if there is similar data in the current driving data. If so, similar historical driving data is obtained to calculate the actual driving range of the target vehicle. Otherwise, historical driving data of the same model as the target vehicle, which is pre-stored in the cloud, is read and matched with the current driving data based on the battery capacity and battery degradation rate of the historical driving data of the same model as the target vehicle. When the number of matching operations reaches a preset threshold, the actual driving range of the target vehicle is calculated based on the historical driving data of the same model as the target vehicle.

[0058] The displayed range is adjusted based on the actual range of the target vehicle.

[0059] In the above embodiments, the actual driving range of the target vehicle can be calculated using the following expression:

[0060] Actual driving range = (battery capacity × (1 - battery degradation rate) / real-time energy consumption per 100 kilometers) × 100.

[0061] In the above embodiment, step S102, which formulates a charging strategy based on the actual driving range, includes: dynamically calculating the charging time and charging pile location based on the actual driving range, the number and availability of charging piles in service areas and non-service areas, and determining the target charging pile location with the shortest charging time as the objective; and formulating a preferred navigation route and an alternative navigation route to reach the target charging pile location; wherein, the preferred navigation route is the navigation route to reach the target charging pile location in the service area; and the alternative navigation route is the navigation route to reach the target charging pile location in the non-service area.

[0062] In the above embodiments, step S103, selecting the charging strategy to send to the driver's side, includes:

[0063] Based on the preferred navigation route, determine the navigation destination during the trip;

[0064] Based on the queuing status or equipment malfunction at the navigation destination, alternative navigation routes are sent to the driver.

[0065] Optionally, when it is necessary to select an alternative navigation route to reach the target charging station in a non-service area, the cloud uses a third-party service operation system to analyze the usage of the target charging station in the non-service area reached by the alternative navigation route, paying attention to whether the charging station is operating normally, whether there are any idle charging stations, the number of vehicles waiting to charge at each charging station, calculating the distance to be traveled and the amount of electricity consumed, etc.

[0066] In the above embodiment, step S103, which determines the charging navigation route based on the driver's feedback on the sent charging strategy, includes: obtaining feedback messages from the driver regarding the preferred or alternative navigation routes; and determining the charging navigation route by reading the driver's acceptance of the navigation destination in the sent charging strategy contained in the feedback messages.

[0067] In the above embodiment, step S104, based on the determined charging navigation route, sends a prompt to the driver's side, and controls the charging navigation route of the target vehicle, including:

[0068] Send a confirmed charging navigation route to the driver's side;

[0069] When the driver adds the navigation destination to the navigation waypoint in the determined charging navigation route, the charging navigation route of the target vehicle is controlled; and when the driver deletes the waypoint based on changes in the actual situation, the target vehicle continues to navigate according to the charging navigation route until the trip ends or the driver actively turns off the charging transmission service, at which point the navigation route prompt is turned off.

[0070] In the above embodiments, the method further includes: after navigation ends, uploading the trip data to the cloud for use in subsequent trips.

[0075] The driving range calculation module 220 is used to calculate the actual driving range of the vehicle during long-distance driving based on the target vehicle's historical travel data, current driving data, and displayed driving range.

[0076] The charging navigation module 230 is used to formulate a charging strategy based on the actual driving range; select a charging strategy to be sent to the driver; and determine a charging navigation route based on the driver's feedback on the sent charging strategy.

[0077] The charging reminder module 240 is used to send a reminder to the driver based on a determined charging navigation route and control the charging navigation route of the target vehicle.
