[0187] The preferred 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.

[0188] It should be noted that the "reservation charging resource" in the embodiment of the present invention refers to a charging method in which the user drives the vehicle to the agreed reservation charging location after making a reservation charging, and the charging service personnel recharges the vehicle on behalf of the user. Specifically, the charging scheme of the "reservation charging resource" is: the charging service terminal obtains the corresponding reservation charging information according to the reservation charging instruction sent by the user terminal, and generates a charging action guide for the customer according to the reservation charging location in the reservation charging information, so that the charging service personnel can complete the charging for the customer according to the charging action guide.

[0189] In the embodiment of the present invention, the energy replenishment service terminal refers to a handheld terminal device used by the energy replenishment service personnel, or a remote terminal device that can communicate with the handheld terminal device. For example, the handheld terminal device can be a mobile phone or a portable computer device, and the remote terminal device can be a server or a server cluster. The user terminal refers to a terminal device that can communicate with the handheld terminal device used by the energy replenishment service personnel and the remote terminal device. For example, the user terminal can be a mobile phone or a portable computer device.

[0190] In the embodiment of the present invention, the “customer energy replenishment action guidance” may be any of the following information guidance:

[0191] First, information guidance for finding the vehicle to be recharged according to the scheduled recharge location, driving the vehicle to be recharged to the recharge resource at a fixed location, recharging the vehicle to be recharged, and returning the recharged vehicle to the scheduled recharge location. According to the information guidance, the recharge service personnel can hand over the vehicle to the user at the scheduled recharge location, drive the vehicle to the recharge resource for recharging, and drive the vehicle back to the scheduled recharge location to return it to the user after recharging is completed. Optionally, in this embodiment, when the recharge resource is a charging resource, the fixed recharge resource can be a charging pile.

[0192] Second, according to the scheduled charging location, the non-fixed charging resource is moved to the vicinity of the vehicle to be charged, the vehicle to be charged is charged, the vehicle charging is completed, and the non-fixed charging resource is moved to the designated location after the service is completed. According to the information guidance, the charging service personnel can directly move the charging resource to the scheduled charging location to charge the vehicle. Optionally, in this embodiment, when the charging resource is a charging resource, the non-fixed charging resource can be a mobile charging vehicle.

[0193] Those skilled in the art will appreciate that the protection scope of the present invention is obviously not limited to the above-mentioned specific scheduled energy replenishment implementation method. Without departing from the principles of the present invention, those skilled in the art may select other scheduled energy replenishment methods to achieve vehicle energy replenishment after the vehicle arrives at the scheduled energy replenishment location. These technical solutions after changes or replacements made to the scheduled energy replenishment will fall within the protection scope of the present invention.

[0194] The following is a description of a vehicle energy replenishment reminder method provided by an embodiment of the present invention in conjunction with the accompanying drawings. Figure 1 , Figure 1 The main steps of a vehicle energy replenishment reminder method in an embodiment of the present invention are exemplarily shown. Figure 1 As shown, the vehicle energy replenishment reminder method in the embodiment of the present invention mainly includes the following steps:

[0195] Step S101: Obtain the driving mode of the vehicle and the predicted mileage.

[0196] Step S102: Determine whether to perform a recharging reminder based on the driving mode and the predicted mileage. Specifically, if a recharging reminder is performed, go to step S103; if not, go to step S105.

[0197] Step S103: Obtain the distribution characteristics of energy replenishment resources in the area where the vehicle is currently located.

[0198] Step S104: outputting energy replenishment reminder information according to the distribution characteristics of energy replenishment resources.

[0199] Optionally, in this embodiment, the energy replenishment reminder information may include voice prompt information, and / or text prompt information, and / or image prompt information.

[0200] Step S105: Do not output energy replenishment reminder information.

[0201] In an embodiment of the present invention, the vehicle energy replenishment reminder method first determines whether to issue an energy replenishment reminder based on the driving mode and the predicted value of the drivable mileage, thereby reducing the misjudgment rate of the user in judging whether energy replenishment is needed based on the remaining energy of the vehicle; at the same time, the vehicle energy replenishment reminder method can also output energy replenishment reminder information based on the distribution characteristics of energy replenishment resources in the area where the vehicle is currently located when it is determined that an energy replenishment reminder is needed, so that the user can timely and effectively understand the distribution of energy replenishment resources in the area where the vehicle is located based on the energy replenishment reminder information, which is conducive to the user to reasonably plan the driving route.

[0202] The above steps S101 to S105 are described in detail below.

[0203] In step S101 of the embodiment of the present invention, the driving mode of the vehicle may include a vehicle cruise mode and a vehicle navigation / route planning mode. The vehicle cruise mode may include a fixed speed cruise mode and an adaptive cruise mode. The vehicle navigation / route planning mode refers to formulating a driving route according to the current position and destination of the vehicle and guiding the vehicle to the destination according to the formulated driving route. Optionally, the vehicle navigation / route planning mode may include a vehicle navigation mode and a route planning mode. The vehicle navigation mode refers to formulating / displaying a driving route according to the current position and destination of the vehicle, monitoring / displaying the actual driving trajectory of the vehicle, and outputting instruction information for guiding the vehicle to travel according to the formulated driving route through voice and / or images, and being able to re-formulate / display the driving route according to the current position of the vehicle when the actual driving trajectory of the vehicle deviates from the formulated driving route. The route planning mode refers to formulating / displaying a driving route according to the current position and destination of the vehicle and monitoring / displaying the actual driving trajectory of the vehicle.

[0204] The predicted mileage value refers to the mileage value that the vehicle can still travel based on the remaining energy of the vehicle, where the mileage value can be expressed in kilometers, and the remaining energy of the vehicle refers to the remaining energy of the vehicle's power source. For example, when the vehicle is an electric vehicle, the remaining energy is the remaining power of the power battery; when the vehicle is a fuel vehicle, the remaining energy is the remaining fuel.

[0205] In step S102 of the embodiment of the present invention, different judgment methods may be used to judge whether to perform a charging reminder according to different driving modes.

[0206] 1. Vehicle Cruise Mode

[0207] When the driving mode is vehicle cruise mode, you can follow the steps below to determine whether to issue a recharging reminder:

[0208] Step 1: Determine whether the predicted drivable mileage value is less than or equal to the preset mileage threshold: If the predicted drivable mileage value is less than or equal to the mileage threshold, go to step 2; if the predicted drivable mileage value is greater than the mileage threshold, go to step 3.

[0209] Step 2: Determine the search value M based on the current position of the vehicle and the first mileage s1 Whether there is a home energy replenishment resource for the current vehicle within the search area with a radius: if so, it means that within the reachable range of the vehicle, the user can drive the vehicle to the home energy replenishment resource for recharging, so no recharging reminder is given; if not, it means that within the reachable range of the vehicle, the user has no home energy replenishment resource available, so a recharging reminder is given.

[0210] In the embodiment of the present invention, s1 =M p ×k 1 , M p and k 1 are the predicted mileage and the preset first mileage coefficient, respectively, and 0<k 1 ≤1. Optionally, in this embodiment of the present invention, k 1 =0.7, the preset mileage threshold is 80km.

[0211] The home energy replenishment resource of a vehicle refers to the energy replenishment resource installed in the fixed residence of the vehicle user, wherein the fixed residence of the vehicle user may be a place where the user lives or works. For example, when the vehicle is an electric car and the energy replenishment resource is a charging pile, the home energy replenishment resource refers to the charging pile installed in the home of the electric car user.

[0212] Step 3: No energy replenishment reminder is given.

[0213] 2. Vehicle Navigation / Route Planning Mode

[0214] When the driving mode is vehicle navigation / route planning mode, you can follow the steps below to determine whether to issue a recharging reminder:

[0215] Step 1: Obtain the vehicle's scheduled driving route.

[0216] Step 2: Determine whether the next destination of the vehicle is located at a point centered on the current location of the vehicle and at a second mileage search value M according to the scheduled driving route. s2 If the next destination is within the search area, no energy replenishment reminder will be given; if the next destination is not within the search area, an energy replenishment reminder will be given. s2 =M p ×k 2 , M p and k 2are the predicted mileage and the preset second mileage coefficient, respectively, and 0<k 2 ≤1. It should be noted that k 1 With k 2 They may be equal or unequal. Optionally, in the embodiment of the present invention, k 2 =0.7.

[0217] In step S103 of the embodiment of the present invention, the distribution characteristics of the energy replenishment resources in the area where the vehicle is currently located may be obtained according to the following steps:

[0218] Step 1: Taking the current position of the vehicle as the center and according to a preset first search radius, determine a first energy replenishment resource search range, wherein the preset first search radius is greater than the predicted drivable mileage value.

[0219] Step 2: Obtain the distance between each energy replenishment resource and the nearest energy replenishment resource within the first energy replenishment resource search range, and obtain the distribution characteristics of the energy replenishment resources according to the minimum distance.

[0220] Specifically, if 0<d min ≤d 1 , then the distribution characteristic of energy replenishment resources is that energy replenishment resources are sufficient; if d 1 <d min ≤d 2 , then the distribution characteristic of energy replenishment resources is that energy replenishment resources are relatively scarce; if d min >d 2 , then the distribution characteristic of energy replenishment resources is the scarcity of energy replenishment resources; among them, d min ,d 1 and d 2 are the minimum distance, the preset first distance threshold and the preset second distance threshold respectively, and d 1 <d 2 Optionally, in the embodiment of the present invention, 1 =10km,d 2 =100km.

[0221] Furthermore, in an optional implementation of the embodiment of the present invention, a step of outputting a destination energy replenishment suggestion may also be included. Specifically, the step of outputting a destination energy replenishment suggestion mainly includes:

[0222] Step 1: Obtain the planned driving route of the vehicle, and obtain the distribution characteristics of the energy replenishment resources in the area where the vehicle is located when it reaches the final destination based on the planned driving route.

[0223] Step 2: Determine whether the distribution feature is a shortage of energy replenishment resources: If the distribution feature is a shortage of energy replenishment resources, output energy replenishment suggestion information, wherein the energy replenishment suggestion information may include the energy replenishment resource closest to the final destination and the corresponding distance, so that the user can decide whether to re-plan the driving route based on the energy replenishment suggestion information to ensure that the remaining power of the vehicle after reaching the final destination can support the vehicle to travel to the nearest energy replenishment resource.

[0224] In step S104 of the embodiment of the present invention, different methods may be used to output energy replenishment reminder information according to different driving modes.

[0225] 1. Vehicle Cruise Mode

[0226] When the driving mode is the vehicle cruise mode, you can determine the output of the energy replenishment reminder information according to the following steps:

[0227] Determine whether the distribution characteristics of the energy replenishment resources in the area where the vehicle is currently located are sufficient energy replenishment resources: if the energy replenishment resources are sufficient, no energy replenishment reminder information is output; if the energy replenishment resources are not relatively scarce (that is, the distribution characteristics are that the energy replenishment resources are relatively scarce or the energy replenishment resources are scarce), then according to the corresponding relationship between the preset distribution characteristics and the energy replenishment reminder information, output the energy replenishment reminder information corresponding to the relatively scarce energy replenishment resources or the scarce energy replenishment resources.

[0228] The correspondence between the distribution characteristics and the energy replenishment reminder information preset in the embodiment of the present invention refers to the correspondence between different distribution characteristics and different energy replenishment reminder information. For example, the energy replenishment reminder information corresponding to the relatively scarce energy replenishment resources can be a voice message "You are currently in an area with relatively scarce energy replenishment resources, it is recommended to replenish energy as soon as possible", and the energy replenishment reminder information corresponding to the scarce energy replenishment resources can be a voice message "You are currently in an area with scarce energy replenishment resources, it is recommended to replenish energy as soon as possible".

[0229] In an optional implementation of the embodiment of the present invention, after outputting the energy replenishment reminder information corresponding to the relatively scarce energy replenishment resources or the scarce energy replenishment resources, the vehicle energy replenishment reminder method may further include a reminder step of entering an area with scarce energy replenishment resources. Specifically, the reminder step of entering an area with scarce energy replenishment resources mainly includes:

[0230] After determining that the current distribution feature is insufficient energy resources, continue to determine whether the previous distribution feature is sufficient energy resources or relatively insufficient energy resources: if the energy resources are sufficient or relatively insufficient, output a reminder message that the vehicle has entered an area with insufficient energy resources. For example, the reminder message that the vehicle has entered an area with insufficient energy resources can be a voice message "You have entered an area with insufficient energy resources, please pay attention to the current power."

[0231] Combine the following Figure 2The vehicle energy replenishment reminder method in which the driving mode is the vehicle cruise mode in the embodiment of the present invention is further described. Figure 2 The main steps of the vehicle energy replenishment reminder method when the driving mode is the vehicle cruise mode are shown as an example. Figure 2 As shown, the vehicle energy replenishment reminder method in the embodiment of the present invention may include the following steps:

[0232] Step S201: Determine whether the predicted mileage is less than or equal to a preset mileage threshold. Specifically, if the predicted mileage is less than or equal to the preset mileage threshold, go to step S202; if the predicted mileage is greater than the preset mileage threshold, go to step S207.

[0233] Step S202: Acquire a search area with the current position of the vehicle as the center and the first mileage search value as the radius.

[0234] Step S203: Determine whether there is a home energy replenishment resource for the current vehicle in the search area. Specifically: if there is a home energy replenishment resource, go to step S207; if there is no home energy replenishment resource, go to step S204.

[0235] Step S204: Obtain the distribution characteristics of energy replenishment resources in the area where the vehicle is currently located.

[0236] Step S205: Determine whether the distribution feature indicates that the energy replenishment resources are sufficient. Specifically, if the distribution feature indicates that the energy replenishment resources are sufficient, go to step S207; if the distribution feature indicates that the energy replenishment resources are not sufficient, go to step S206.

[0237] Step S206: outputting energy replenishment reminder information indicating that energy replenishment resources are relatively scarce or corresponding to the shortage of energy replenishment resources according to the corresponding relationship between the preset distribution characteristics and the energy replenishment reminder information.

[0238] Step S207: Do not output energy replenishment reminder information.

[0239] 2. Vehicle Navigation / Route Planning Mode

[0240] When the driving mode is vehicle navigation / route planning mode, you can follow the steps below to determine the output of the energy replenishment reminder information:

[0241] Step 1: Determine whether the distribution characteristics indicate a shortage of energy resources.

[0242] Step 2: When the distribution feature is a shortage of energy replenishment resources, output energy replenishment reminder information corresponding to the shortage of energy replenishment resources according to the correspondence between the preset distribution feature and the energy replenishment reminder information. The "correspondence between the preset distribution feature and the energy replenishment reminder information" is the same as the "correspondence between the preset distribution feature and the energy replenishment reminder information" in the embodiment in which the driving mode is the vehicle cruise mode, and is not repeated here for the sake of brevity.

[0243] Step 3: When the distribution characteristic is that the energy replenishment resources are sufficient or the energy replenishment resources are relatively scarce, obtain the driving label of the current vehicle, and according to the correspondence between the preset driving label and the reminder mileage threshold, obtain the reminder mileage threshold corresponding to the driving label of the current vehicle, and then go to step 4.

[0244] Step 4: Determine the mileage comparison value M c Whether the obtained reminder mileage threshold has been reached: If M c If the reminder mileage threshold has been reached, the energy replenishment reminder information corresponding to sufficient energy replenishment resources or relatively scarce energy replenishment resources is output according to the correspondence between the preset distribution characteristics and the energy replenishment reminder information; if M c If the reminder mileage threshold is not reached, no energy replenishment reminder information will be output. c =M p ×k 3 , M p and k 3 are respectively the predicted mileage value and the preset third mileage coefficient, and 0<k 3 ≤1. It should be noted that k 1 , k 2 and k 3 They may be equal or unequal. Optionally, in the embodiment of the present invention, k 3 =0.7. For example, when the reminder mileage threshold is 80km, it is determined that M c Whether it reaches 80km, if it reaches it, output the energy replenishment reminder information, if it does not reach it, go to step 1 and repeat steps 1-4. Optionally, in the embodiment of the present invention, the reminder mileage threshold can be one or more. For example, the reminder mileage threshold can include 10km and 80km, that is, in M c When the mileage reaches 10km and 80km, the charging reminder information is output respectively, so as to achieve the purpose of reminding the user multiple times.

[0245] Optionally, in an optional implementation of an embodiment of the present invention, the number of reminders can be obtained according to the following steps, and the energy replenishment reminder information corresponding to sufficient energy replenishment resources or relatively scarce energy replenishment resources can be output according to the number of reminders: First, according to the correspondence between the preset driving label and the number of reminders, the number of reminders corresponding to the driving label of the current vehicle is obtained. Then, according to the obtained number of reminders, the energy replenishment reminder information corresponding to sufficient energy replenishment resources or relatively scarce energy replenishment resources is output. Among them, the number of reminders refers to the number of times the energy replenishment reminder information is output.

[0246] Optionally, in another optional implementation of the embodiment of the present invention, after outputting the energy replenishment reminder information corresponding to sufficient energy replenishment resources or relatively scarce energy replenishment resources, an energy replenishment resource arrival reminder step may also be included. Specifically, the energy replenishment resource arrival reminder step mainly includes:

[0247] Step 1: Obtain the vehicle's scheduled driving route, and determine whether the vehicle is traveling near an energy replenishment resource based on the scheduled driving route. When the vehicle is traveling near an energy replenishment resource, output a reminder message indicating that the vehicle has reached the energy replenishment resource, and then determine whether the vehicle is replenishing energy at the energy replenishment resource.

[0248] Step 2: If the vehicle is recharging at the recharging resource, the environment information of the recharging resource is obtained and the recommended leisure place information is output according to the environment information, for example, a restaurant or a shopping mall.

[0249] Step 3: If the vehicle does not recharge at the recharging resource, determine whether the distance the vehicle has traveled from the recharging resource has reached a preset third distance threshold: if reached, output again the corresponding recharging reminder information indicating that the recharging resource is sufficient or scarce. Optionally, in the embodiment of the present invention, the preset third distance threshold may be 5 km, that is, the reminder is issued again after the vehicle has traveled 5 km away from the recharging resource, to prevent the user from regretting not recharging at the recharging resource and becoming more hesitant when the vehicle is too far away from the recharging resource.

[0250] In an embodiment of the present invention, the driving tag may include travel characteristics and user characteristics. The travel characteristics may include travel range, travel time and travel weather. The user characteristics may include whether the user is skilled in driving, whether the user is familiar with the vehicle's scheduled driving route, the user's personal energy replenishment resource information and energy replenishment preference characteristics.

[0251] Specifically, in the embodiment of the present invention, the travel range, travel time and travel weather can be obtained respectively according to the following steps:

[0252] Step 1: Obtain the vehicle's scheduled driving route and determine whether the scheduled driving route includes a highway: if it includes a highway, the travel range is a highway travel range; if it does not include a highway, the travel range is a non-highway travel range.

[0253] Step 2: Get the travel time according to the date and time period of the vehicle travel, which includes the vehicle travel peak time on statutory working days, the vehicle travel non-peak time on statutory working days, and statutory holidays. For example, the vehicle travel peak time on statutory working days can be 7:00-9:00 and 18:00-20:00 on Monday.

[0254] Step 3: Acquire the travel weather according to the weather information when the vehicle travels, and the travel weather includes severe weather and non-severe weather. For example, severe weather may be heavy rain, hail, and heavy snow.

[0255] In the embodiment of the present invention, user characteristics can be obtained according to the following steps:

[0256] Step 1: Determine whether the user's historical cumulative driving time is greater than or equal to a preset time threshold: if yes, it is determined that the user is skilled in driving; if not, it is determined that the user is unskilled in driving. Optionally, in this embodiment of the present invention, the preset time threshold may be 100 hours.

[0257] Step 2: Taking the current position of the vehicle as the center and according to the preset second search radius, determine the second energy resource search range, and according to the user's history of using energy resources, determine whether there is an energy resource that the user has used before within the second energy resource search range: if so, it is determined that the user is familiar with the vehicle's scheduled driving route; if not, it is determined that the user is not familiar with the vehicle's scheduled driving route. Optionally, in this embodiment of the present invention, the preset second search radius can be 10km.

[0258] Step 3: Determine whether the user owns personal energy replenishment resources: If the user owns personal energy replenishment resources: then obtain personal energy replenishment resource information according to the type of personal energy replenishment resources: If the user does not own personal energy replenishment resources, then the personal energy replenishment resource information is that the user does not own personal energy replenishment resources. Among them, personal energy replenishment resources may include household energy replenishment resources and scheduled energy replenishment resources. For example, when personal energy replenishment resources include household energy replenishment resources, the personal energy replenishment resource information may be "owning household resources"; when personal energy replenishment resources include household energy replenishment resources and scheduled energy replenishment resources, the personal energy replenishment resource information may be "owning both household and scheduled resources". It should be noted that the "household energy replenishment resources" and "scheduled energy replenishment resources" in the embodiments of the present invention are respectively the same as the "household energy replenishment resources" and "scheduled energy replenishment resources" in the aforementioned embodiments. For the sake of brevity, they will not be repeated here.

[0259] Step 4: Obtain the user's energy replenishment resource type preference characteristics, energy replenishment frequency preference characteristics, and energy replenishment route preference characteristics, and obtain the energy replenishment preference characteristics based on the energy replenishment resource type preference characteristics, energy replenishment frequency preference characteristics, and energy replenishment route preference characteristics.

[0260] Specifically, the energy replenishment resource type preference feature may include the energy replenishment resource type to be used preferentially. The energy replenishment route preference feature may include the priority use of a driving route that other vehicles have traveled, wherein the starting point and the final destination of the driving route are respectively close to the starting point and the final destination of the current vehicle, and the driving route includes one or more energy replenishment resource waypoints, that is, when driving according to the driving route, the vehicle user can decide whether to recharge at the energy replenishment resource waypoint according to actual needs. The energy replenishment number preference feature may include the minimum number of energy replenishments, the maximum vehicle energy maintenance, and the maximum vehicle driving speed. Among them, the minimum number of recharges means the minimum number of recharges during the entire driving process, indicating that the user is very anxious about the waiting time for recharges. Therefore, the number of recharges should be reduced as soon as possible to reduce the anxiety about the waiting time; maintaining maximum vehicle energy means maintaining the vehicle energy close to the maximum throughout the driving process, indicating that the user is very anxious about energy loss. Therefore, even if the vehicle is recharged several times, the user hopes that the vehicle energy will be maintained close to the maximum value to reduce anxiety; the maximum vehicle speed means maintaining the vehicle speed close to the maximum speed value corresponding to each driving section throughout the driving process, indicating that the user does not care about energy consumption, but pays more attention to the driving experience of the vehicle.

[0261] The following takes the example of the trip label including "travel range", "whether the user is skilled in driving" and "whether the user is familiar with the scheduled driving route of the vehicle" to specifically explain the "correspondence between the preset driving label and the reminder mileage threshold" and the "correspondence between the preset driving label and the number of reminders". In this embodiment, for the sake of simplicity, the "high-speed travel range", "non-high-speed travel range", "user is skilled in driving", "user is unskilled in driving", "user is familiar with the scheduled driving route of the vehicle" and "user is not familiar with the scheduled driving route of the vehicle" are described as "highway", "urban area", "experienced driver", "new driver", "familiar itinerary" and "unfamiliar itinerary", and the reminder mileage threshold includes four thresholds of 10km, 60km, 80km and 100km. Refer to Table 1, which exemplifies the correspondence between the driving label, the reminder mileage threshold and the number of reminders in the embodiment of the present invention.

[0262] Table 1

[0263] Driving Labels Reminder times Reminder mileage threshold Urban area, new driver, familiar with the route 2 60km and 10km Urban area, experienced driver, familiar with the itinerary 1 10km High speed, new driver, familiar with the route 2 80km and 10kn High speed, experienced driver, familiar with the itinerary 1 60km Urban areas, new drivers, unfamiliar itineraries 2 60km and 10km Urban area, experienced driver, unfamiliar itinerary 1 10km Highways, new drivers, unfamiliar itineraries 3 100km, 80km and 10km High speed, experienced driver, unfamiliar itinerary 2 80km and 10km

[0264] Combine the following Figure 3 The vehicle energy replenishment reminder method in the embodiment of the present invention when the driving mode is the vehicle navigation / route planning mode is further described. Figure 3 The main steps of the vehicle energy replenishment reminder method when the driving mode is the vehicle navigation / route planning mode are exemplarily shown. Figure 3 As shown, the vehicle energy replenishment reminder method in the embodiment of the present invention may include the following steps:

[0265] Step S301: Obtain the vehicle's scheduled driving route.

[0266] Step S302: Acquire a search area with the current position of the vehicle as the center and the second driving distance search value as the radius.

[0267] Step S303: Determine whether the next destination of the vehicle is within the search area according to the scheduled travel route. Specifically, if it is within the search area, go to step S311; if not, go to step S304.

[0268] Step S304: Obtain the distribution characteristics of the energy replenishment resources in the area where the vehicle is currently located.

[0269] Step S305: Determine whether the distribution feature is a shortage of energy replenishment resources. Specifically, if the distribution feature is a shortage of energy replenishment resources, go to step S310. If the distribution feature is not a shortage of energy replenishment resources, go to step S306.

[0270] Step S306: Obtain the driving tag of the current vehicle.

[0271] Step S307: According to the preset correspondence between the driving label and the reminder mileage threshold, the reminder mileage threshold corresponding to the driving label of the current vehicle is obtained.

[0272] Step S308: Determine whether the drivable mileage comparison value reaches the acquired reminder mileage threshold. Specifically, if the drivable mileage comparison value reaches the reminder mileage threshold, go to step S309; ​​if the drivable mileage comparison value does not reach the reminder mileage threshold, go to step S311;

[0273] Step S309: outputting energy replenishment reminder information corresponding to sufficient energy replenishment resources or relatively scarce energy replenishment resources according to the corresponding relationship between the preset distribution characteristics and the energy replenishment reminder information.

[0274] Step S310: outputting energy replenishment reminder information corresponding to the shortage of energy replenishment resources according to the corresponding relationship between the preset distribution characteristics and the energy replenishment reminder information.

[0275] Step S311: Do not output energy replenishment reminder information.

[0276] In step S105 of the embodiment of the present invention, when the driving mode is the route planning mode, after outputting the energy replenishment reminder information, a step of re-planning the driving route may be included. Specifically, the step of re-planning the driving route mainly includes:

[0277] Step 1: Reset the driving route and display the available energy replenishment resources along the driving route and its vicinity according to the current location, final destination and user characteristics of the vehicle. The reset driving route includes one or more energy replenishment resource waypoints. It should be noted that the "user characteristics" in this embodiment are the same as the "user characteristics" in the previous embodiment, and will not be repeated here for the sake of brevity.

[0278] Step 2: Determine whether a user-input energy resource waypoint modification instruction is received: If a user-input energy resource waypoint modification instruction is received, modify the energy resource waypoints specified by the energy resource waypoint modification instruction in the driving route according to the energy resource waypoint modification instruction, and then go to step 3; if no user-input energy resource waypoint modification instruction is received, go directly to step 3.

[0279] Step 3: Determine whether a driving route confirmation instruction input by the user is received: if a driving route confirmation instruction is received, guide the vehicle to travel according to the route; if no driving route confirmation instruction is received, continue to guide the vehicle to travel according to the original route.

[0280] In step S105 of the embodiment of the present invention, when the driving mode is the vehicle navigation / route planning mode, after outputting the energy replenishment reminder information, an energy replenishment resource display step may be included. Specifically, the energy replenishment resource display step mainly includes:

[0281] Step 1: Determine whether the display screen of the vehicle display device is a navigation / route planning map. Specifically, if the display screen is a navigation / route planning map, go to step 2; if the display screen is not a navigation / route planning map, go to step 3.

[0282] Step 2: With the vehicle's current position as the center and the predicted drivable mileage as the radius, obtain the vehicle's drivable range and the location information of the energy replenishment resources within the drivable range, control the vehicle display device to display the energy replenishment resource map and display the corresponding energy replenishment resources in the energy replenishment resource map according to the location information.

[0283] Step 3: Output resource display reminder information and determine whether a confirmation instruction based on the user's feedback on the resource display reminder information is received: if so, control the vehicle display device to display the energy replenishment resource map and display the corresponding energy replenishment resources in the energy replenishment resource map according to the location information; if not, output energy replenishment suggestion information, wherein the energy replenishment suggestion information may include the energy replenishment resource closest to the vehicle and the corresponding distance.

[0284] In the embodiment of the present invention, the navigation / route planning map refers to a map that guides the vehicle to the destination in the vehicle navigation / route planning mode, and the energy resource map refers to a map that records the location, type and other information of the energy resource. The energy resource map can be used to quickly view the energy resource information at any location.

[0285] In step S105 of the embodiment of the present invention, after outputting the energy replenishment reminder information, a determination step of outputting the energy replenishment reminder information again is also included.

[0286] Specifically, the judgment step of outputting the energy replenishment reminder information again mainly includes: obtaining the running status information of the vehicle, and judging whether to output the energy replenishment reminder information again according to the change status of the running status information. In the embodiment of the present invention, a reminder operation can be performed once in each running state, and a reminder operation is performed again when the running state changes, and the main step of this reminder operation is to repeatedly output the energy replenishment reminder information output by the last reminder operation, so as to avoid the problem of increased workload caused by performing reminder operations multiple times in each running state; at the same time, since the number of reminders in each reminder operation can be determined according to the distribution characteristics of the energy replenishment resources, even if the reminder operation is only performed once in each running state, the purpose of reminding the user multiple times can be achieved by setting the number of reminders; when the running state changes, the reminder is performed by repeatedly outputting the energy replenishment reminder information output by the last reminder operation, which further reduces the running workload.

[0287] Optionally, in an optional implementation of the embodiment of the present invention, the operating status information may include the vehicle's driving mode, the vehicle computer login user, the vehicle computer sleep / wake-up mode and the real-time energy value. At this time, the following steps may be followed to determine whether to output the energy replenishment reminder information again:

[0288] If the driving mode or the user logged in to the vehicle computer changes, the energy replenishment reminder information is output again; if the vehicle computer switches from sleep mode to wake-up mode, the energy replenishment reminder information is output again; if the energy value of the real-time energy value that rises and then decreases within a period of time is greater than or equal to the preset first energy threshold, the energy replenishment reminder information is output again. In the embodiment of the present invention, since there are short-term energy fluctuations in the actual operation of the vehicle, for example, the energy value of the vehicle will fluctuate when the vehicle goes uphill and then downhill, therefore, by judging whether the energy value of the real-time energy value that rises and then decreases within a period of time (i.e., within a longer period of time) is greater than or equal to the first energy threshold, it is determined whether to output the energy replenishment reminder information again, which can avoid repeated reminders in a short period of time and affect the user's driving experience.

[0289] Furthermore, in an embodiment of the present invention, when the driving mode is the vehicle navigation / route planning mode, a step of displaying driving route related information may also be included. The driving route related information mainly includes the predicted value of remaining energy after the vehicle reaches the final destination, whether the vehicle can return after reaching the destination, the predicted value of the number of energy replenishment times, the energy value that the vehicle needs to replenish at each energy replenishment resource passing point, vehicle service area related information, weather information, journey time and travel time. The following is a specific description of the display steps of the above driving route related information.

Among them, the refueling resource waypoint refers to a waypoint on the scheduled driving route that is a refueling resource.

[0293] Step 2: Determine whether the remaining energy prediction value is greater than or equal to the return energy prediction value: If the remaining energy prediction value is greater than or equal to the return energy prediction value: output and display a prompt message that the vehicle can return; if the remaining energy prediction value is less than the return energy prediction value, output and display a prompt message that the vehicle cannot return.

[0294] 2. Prediction of the number of energy replenishment times

[0295] Specifically, you can obtain the predicted value of the number of energy replenishment times by following the steps below:

[0296] The vehicle's scheduled driving route is obtained, and it is determined whether the scheduled driving route includes a waypoint for energy replenishment resources. When the scheduled driving route includes a waypoint for energy replenishment resources, a predicted value of the number of energy replenishment times is obtained and displayed according to the number of waypoints for energy replenishment resources.

[0297] 3. The amount of energy that the vehicle needs to replenish at each energy resource point

[0298] Specifically, the energy value that the vehicle needs to replenish at each energy replenishment resource waypoint can be obtained by following the steps below:

[0299] Step 1: Obtain the vehicle's scheduled driving route and determine whether the scheduled driving route includes a refueling resource waypoint.

[0300] Step 2: When the scheduled driving route includes an energy replenishment resource waypoint, the energy value that needs to be replenished at the energy replenishment resource waypoint is calculated and displayed based on the distance between the energy replenishment resource waypoint and the final destination.

[0301] Step 3: When the scheduled driving route includes multiple energy replenishment resource waypoints, determine whether each energy replenishment resource waypoint is the last energy replenishment resource waypoint in turn according to the preset energy replenishment resource waypoint judgment order: if the current energy replenishment resource waypoint is the last energy replenishment resource waypoint, calculate and display the energy value that needs to be replenished at the current energy replenishment resource waypoint based on the distance between the current energy replenishment resource waypoint and the final destination; if the current energy replenishment resource waypoint is not the last energy replenishment resource waypoint, calculate and display the energy value that needs to be replenished at the current energy replenishment resource waypoint based on the distance between the current energy replenishment resource waypoint and the next energy replenishment resource waypoint.

[0302] IV. Information about vehicle service areas

[0303] Specifically, you can obtain information about the vehicle service area by following the steps below:

[0304] Step 1: Obtain the vehicle's scheduled driving route.

[0305] Step 2: According to the scheduled driving route, obtain the vehicle service area located near the scheduled driving route, and query whether there are energy replenishment resources in the vehicle service area: if so, obtain and display the resource information of the energy replenishment resources; if not, display the prompt information that there are no energy replenishment resources in the vehicle service area. Among them, the resource information may include the attribute information, working status and distance between the energy replenishment resources and the vehicle. The attribute information refers to the energy output power, location and quality of the energy replenishment resources, which can characterize the nature of the energy replenishment resources. The working status may include whether the energy replenishment resources are in an idle state or in a non-idle state.

[0308] The vehicle's scheduled driving route is obtained, and real-time weather information near the scheduled driving route is obtained and displayed according to the scheduled driving route.

[0309] 6. Journey time and travel time

[0310] Specifically, you can obtain the journey time and travel time by following the steps below:

[0311] Step 1: Obtain the vehicle's scheduled driving route and determine whether the scheduled driving route includes a recharging resource waypoint. Specifically, if the scheduled driving route includes a recharging resource waypoint, go to step 2; if the scheduled driving route does not include a recharging resource waypoint, go to step 3.

[0312] Step 2: Based on the remaining energy of the vehicle when the vehicle arrives at the energy replenishment resource waypoint, predict the recharging time required for the vehicle to replenish its energy to a preset second energy threshold when recharging at the energy replenishment resource waypoint, and predict the vehicle's journey time based on the route length of the scheduled driving route, and obtain and display the vehicle's travel time based on the cumulative sum of the journey time and the recharging time corresponding to each energy replenishment resource waypoint.

[0313] Step 3: Predict and display the vehicle's journey time based on the route length of the scheduled driving route.

They can be executed simultaneously (in parallel) or in a reverse order. These simple changes are within the scope of protection of the present invention.
