In order to solve the technical problems that the current scheme of displaying energy supply in navigation can cause a user to cancel the current navigation and search again, and the vehicle driving efficiency and the energy supply efficiency are influenced, the invention provides a navigation method, which has the following overall thought:

responding to a navigation request of a user, and acquiring a navigation route corresponding to the navigation request; determining a target search range according to the navigation route and the first distance; determining a target energy supply station within the target search range; and sending the target energy supply station to a navigation interactive interface where the navigation route is located.

The principle of the scheme is as follows: the method comprises the steps that a target energy supply station located in a target searching range around a navigation route is determined according to the navigation route and a first distance value of a vehicle in the current driving process, and the target energy supply station is automatically sent to a navigation interaction interface, so that the navigation interaction interface displays the target energy supply station located around the current navigation route, a driver can select a mode of directly performing energy supply in the past, and the situation that the current navigation is cancelled to search the energy supply station again is avoided; or a mode that a target energy supply station generates a new navigation route can be selected, so that the energy supply station is prevented from being searched again; in general, the scheme improves the running efficiency and the energy supply efficiency of the vehicle and reduces unnecessary energy loss.

The method can be applied to the field of electric vehicles, such as pure electric vehicles or hybrid electric vehicles, and can also be applied to the field of fossil energy vehicles, such as fuel vehicles and gas vehicles; the method can be implemented at a vehicle-mounted navigation equipment end, and also can be implemented at a mobile electronic device with navigation service, such as a mobile phone, a tablet personal computer and other equipment ends.

In the following, the above-described embodiments will be described in detail with reference to the specific embodiments.

In an alternative embodiment, as shown in fig. 1, the solution provided by the present invention is applied to a smartphone device, and a navigation method thereof includes:

s1: and responding to a navigation request of a user, and acquiring a navigation route corresponding to the navigation request.

Currently, a user (driver) navigates using a navigation application before driving one time. After the user enters the destination on the navigation application, the navigation application may generate a navigation route from the current location to the destination location.

S2: and determining a target search range according to the navigation route and the first distance.

Specifically, the first distance may be a preset search distance, or may be a specified distance obtained in response to an input by the user. A target search range, which may be a range having the navigation route as a center line and having a distance from the navigation route not exceeding the first distance; the navigation route may be a boundary line, and a range not exceeding the first distance from the navigation route may be provided on one side of the navigation route. The target search range using the navigation route as the boundary line is often found in a road section running by a river or a mountain road. The magnitude of the first distance value may be determined according to actual requirements, such as 50 meters to 1000 meters, and is not specifically limited herein.

S3: and determining the target energy supply station within the target search range.

After the target search range is determined, the target energy supply stations located within the target search range can be searched next. The energy supply station refers to a fossil energy supply station and a charging station, and the fossil energy supply station comprises a gas station, a gas station and the like.

Determining the target energy supply station within the target search range, which can adopt one or more of the following modes:

the first method is as follows: judging the vehicle type of the vehicle, wherein the vehicle type comprises an electric vehicle or a fuel vehicle; and determining a target energy supply station within the target search range according to the vehicle type.

Specifically, if the vehicle is a fuel vehicle, only gas stations within the target search range are searched as target energy supply stations; if the vehicle is a pure electric vehicle, only the charging stations in the target search range are searched as target energy supply stations; if the vehicle is a hybrid vehicle, the charging station and the gas station within the target search range can be simultaneously searched as the target energy supply station. By searching the energy supply stations matched with the vehicle types of the vehicle, the searching efficiency can be improved, and the invalid searching of the energy supply stations which are not matched with the vehicle types is avoided.

The second method comprises the following steps: acquiring road condition information in the target search range; and determining the target energy supply station according to the target search range and the road condition information.

Specifically, the road condition information includes information of a traffic jam road section, a road repair road section and the like, and because a large amount of traffic time is delayed due to traffic jam and road repair and poor driving experience is caused, the road condition information is preferably searched for, such as national roads, provincial roads, main roads in urban areas and the like, and energy supply stations which are not traffic jam on the roads are used as target energy supply stations. The target energy supply station is determined by combining the road condition, so that the energy supply time can be saved, and the energy supply efficiency and the driving efficiency can be improved.

Considering that the energy supply station may be queuing after the host vehicle arrives at the energy supply station, and therefore, in order to avoid this situation, the user needs to wait or search for the energy supply station again when arriving, and the energy supply efficiency is reduced, the embodiment provides a method for ensuring the target energy supply station in an idle state when the host vehicle arrives as much as possible, specifically as follows:

acquiring estimated time of the vehicle reaching each energy supply station in the target search range and historical energy supply information of each energy supply station; determining the target energy supply station according to the estimated time and the historical energy supply information; and the target energy supply station is an energy supply station which is in an idle state when the vehicle arrives at the estimated time.

The energy supply station in an idle state refers to an energy supply station which is directly available without queuing. For example, a charging station in an idle state refers to a charging station that includes at least one charging post that is not being used; a gasoline station in an idle state refers to a gasoline station comprising at least one unused fuel gun.

For example, if there are three energy replenishment stations A, B, C in the target search range, the time a at which the vehicle arrives at a, the time B at which the vehicle arrives at B, and the time C at which the vehicle arrives at C are estimated, and then, in conjunction with the historical energy replenishment information, it is determined whether a is idle at time a, whether B is idle at time B, and whether C is idle at time C. According to the above scheme, the energy replenishment station in an idle state at the corresponding time is selected as the target energy replenishment station, and if the energy replenishment station is idle at time B, the energy replenishment station B is set as the target energy replenishment station.

The estimated time of the vehicle reaching each energy supply station is determined, the current position of the vehicle can be obtained through a GPS positioning function of the mobile phone, and the position of each energy supply station in the target search range is obtained through a navigation map; determining the driving mileage of the vehicle from the current position to each energy supply station according to the position information; the estimated time to reach each energy replenishment station may then be determined taking into account the historical or current travel average speed of the host vehicle. Optionally, the estimated time may be adjusted or corrected by combining road condition information of the energy supply station.

The historical energy replenishment information of the energy replenishment station is information reflecting the historical energy replenishment situation of the energy replenishment station. For a fossil energy supply station, such as a gas station, the historical energy supply information may include the number of fuel guns in the gas station, the number of vehicles entering the station to be refueled per unit time as a function of time, the number of vehicles leaving the station to be refueled per unit time, and so forth. For a charging station, the historical energy replenishment information may include the number of charging piles of the charging station, the number of vehicles charged at the arrival of the charging pile per unit time, the number of vehicles charged at the departure of the charging pile per unit time, the average charging time consumed for charging an electric vehicle using a charging pile, and the like. The historical energy supply information can be stored in a server or a mobile phone local place after being processed by collecting historical data of the energy supply station, and can be continuously updated along with time.

Based on the historical energy replenishment information and the estimated time, it can be determined whether the energy replenishment station is idle when the host vehicle arrives at the energy replenishment station. An optional mode is that statistical analysis of a large amount of historical energy replenishment information can obtain the number of idle energy replenishment mechanisms in the energy replenishment station at any time, that is, the historical energy replenishment information includes a mapping relationship between the number of idle energy replenishment mechanisms and time, and then it can be determined whether the energy replenishment station is idle when the vehicle arrives directly according to the estimated time, specifically, the following is performed:

determining the target energy replenishment station according to the estimated time and the historical energy replenishment information, comprising: acquiring the current moment; determining the arrival time of the vehicle to each energy supply station according to the current time and the estimated time; determining the number of idle energy supply mechanisms in the energy supply station when the vehicle arrives according to the arrival time and the mapping relation; and determining the energy supply stations with the number of the idle energy supply mechanisms more than one as the energy supply stations.

For a gas station, the energy supply mechanism is a fuel gun; for the charging station, the energy supply mechanism is a charging pile.

Taking a charging station as an example, the mapping shown in table 1 is obtained by collecting and analyzing a large amount of historical charging information of the charging station A, B, C:

table 1: mapping relation example

Time	Idle charging pile quantity/A	Idle charging pile quantity/B	Idle charging pile quantity/C
				……
15:30	6	3	0
				15:40	5	1	1
15:50	2	0	2
				16:00	3	0	4
16:10	4	0	2
				……

For example, if it is determined that the vehicle arrives at charging station a at 16:00, charging station B at 15:50, and charging station C at 16: 10. Respectively inquiring the table 1 to know that 3 idle charging piles are estimated when the charging pile arrives at the charging station A, the number of the idle charging piles when the charging pile arrives at the charging station B is 0, and the number of the idle charging piles when the charging pile arrives at the charging station C is 2; the charging station A, C may act as the target energy supply station.

In general, the third mode is characterized in that the energy supply station which is in the idle state when the energy supply station arrives is taken as the target energy supply station, so that the situation that the energy supply station is queued when the user arrives, the user spends a large amount of time waiting or searches other energy supply stations again is avoided, and the driving efficiency and the energy supply efficiency are obviously improved.

For the situation that the energy supply station is a charging station, the automobile refueling speed is high at present, and the gas station is well constructed and has a large number, so that the queuing refueling condition rarely occurs. The electric automobile is a vehicle type which is rapidly developed in recent years, on one hand, the construction of a charging station has geographical differences, some places are more in construction, and some places are deficient; on the other hand, charging standards of the charging stations are more, and quick charging is not yet fully covered, so that the situation of queuing charging becomes very common in areas with few charging station layouts. Therefore, in order to avoid queuing of the charging stations when the user arrives at the charging stations, the target energy supply station can be determined in a fourth way:

determining the number of idle charging piles of each charging station in the target search range; and determining the charging stations with the number of the idle charging piles larger than the preset number as the target energy supply stations.

And taking the charging station with more idle charging piles in the target search range as the target charging station. This is to avoid a situation where the user has to wait or find another charging station when he drives his car to the charging station, just full of charging stations or in line. Optionally, the preset number may be set as required, for example, 3 to 10. The purpose of this scheme is to confirm the current idle charging station as the target charging station, has simple easy characteristics of implementing, to the information of how many idle charging piles of some charging station at present, can directly inquire the corresponding supplier on the network.

S4: and sending the target energy supply station to a navigation interactive interface where the navigation route is located.

After the target energy supply stations within the target search range are determined, the target energy supply stations are sent to the navigation interactive interface, and therefore the target energy supply stations can be displayed on the navigation interactive interface. These target energy supply stations are not limited to energy supply stations through which the navigation route passes directly, but include energy supply stations located around the navigation route. After the user generates the energy supply demand, the user can directly drive the vehicle to the target energy supply station close to the current navigation route without searching the nearby energy supply station again and canceling the current navigation route. For the target energy supply station far away from the current navigation route, the user can directly select the target energy supply station on the navigation interactive interface to generate the navigation route without searching again, so that the driving efficiency and the energy supply efficiency are improved.

Optionally, in the case that the energy supply station is a charging station, considering that there may be a plurality of target charging stations around the navigation route, in order to display the target charging station that is optimal and matches the actual demand of the user, the navigation method may further include:

after the target energy supply station is determined, determining a charging station meeting the preset requirement of the vehicle from the target charging stations; the preset requirements of the host vehicle comprise one or more of the following: presetting a charging type, a charging price, a charging brand, a charging discount and a user score; and sending the charging station meeting the preset requirement of the vehicle to the navigation interactive interface.

For the charging types, the charging types of the existing charging piles on the market at present include slow charging, fast charging, super fast charging and the like, so that a target charging station with the charging type matched with the charging type can be used as a new navigation destination according to the charging type or the charging standard corresponding to the vehicle.

For the charging price, if a plurality of selectable targets exist, the charging price can be advantageous, and the target charging pile lower than the preset price is preferentially determined as a new navigation terminal.

For the charging brand, charging piles provided by two brands of merchants are commonly used for users, and corresponding rechargeable cards are transacted, so that a target charging station with the charging brand meeting the preset requirements of the users can be determined as a new navigation terminal.

For the charging discount, charging discounts, charging preferential benefits and the like may exist in charging stations of some brand merchants at present, and then a target charging station with the discount strength greater than the preset discount may be determined as a new navigation destination.

For the user score, it well reflects the charging service level of the brand merchant, and thus a target charging station having a user score greater than a preset score may be determined as a new navigation destination.

Further, the sending the charging station meeting the preset requirement of the vehicle to the navigation interactive interface includes: sending the charging station meeting the preset requirement of the vehicle and charging pile information corresponding to the charging station meeting the preset requirement of the vehicle to the navigation interactive interface; the charging pile information comprises at least one of the number of idle charging piles, the charging type, the charging price, the charging brand, the charging discount and the user score.

Through show the stake information of charging of every target charging station at navigation interactive interface, can convenience of customers decide which target charging station to go to.

On the other hand, for an electric vehicle, since the fast charge also takes at least half an hour, while on the way of travel, the user may need to rest or eat after driving for a long time, and therefore, optionally, after the determination of the target energy replenishment station, the navigation method further includes:

determining a charging station associated with a target object from the target charging stations; the target object comprises a restaurant or hotel; the sending the target energy supply station to the navigation interactive interface where the navigation route is located comprises: and sending the charging station associated with the target object to the navigation interactive interface.

Specifically, according to the scheme, a search radius can be preset for searching restaurants and hotels near the target charging station, or the search can be performed by taking the target charging station as the center of a circle according to the search radius specified by the user. In order to avoid the user walking too far, the search radius may be 50-100 meters. Through the scheme, the target charging station which can provide diet or accommodation nearby is used as a new navigation terminal, so that a user can conveniently find diet or accommodation after parking and charging, the fatigue of the user can be relieved, and the service experience is improved.

In summary, the embodiment provides a navigation method, by determining a target energy supply station located in a target search range around a navigation route, when a driver is supported to have a requirement for energy supply midway, the driver can directly see the energy supply station around the current navigation route from a navigation interactive interface, so that the driver can select to directly perform energy supply in the past, and the current navigation is avoided being cancelled to search the energy supply station again; or the driver is supported to select one energy supply station to generate a new navigation route, so that the energy supply station is prevented from being searched again; furthermore, the estimated time of the vehicle reaching each energy supply station is considered, and the energy supply station in an idle state when the vehicle arrives is determined as the target energy supply station by combining the historical energy supply information corresponding to the energy supply stations, so that the user is prevented from waiting when arriving, or searching for other energy supply stations again. In general, the scheme improves the running efficiency and the energy supply efficiency of the vehicle and reduces unnecessary energy loss.

In the foregoing embodiment, the target energy replenishment stations located around the navigation path are sent to the navigation interactive interface, so that the user can go to the supplemental energy conveniently. When the vehicle runs for a long distance, the energy supplement needs often appear on half way due to the limitation of the cruising ability. In view of the fact that the energy supply stations determined by navigation are to be combined with the cruising ability of the vehicle, and in order to display the energy supply stations in a targeted manner, in another alternative embodiment, as shown in fig. 2, at S3: after determining the target energy replenishment station, the navigation method further comprises:

s311: and acquiring the residual energy of the vehicle.

Specifically, for a fuel-powered automobile, the current remaining energy refers to the remaining gasoline quantity or the remaining diesel quantity of a fuel tank of the automobile; for pure electric vehicles, the current residual energy refers to the electric quantity SOC of the power battery, and for hybrid vehicles, the current residual energy includes the electric quantity of the power battery and the residual gasoline quantity. The time for acquiring the remaining energy may be the time for responding to the navigation request of the user, or may be the time for acquiring the remaining energy in real time during the driving process, which is not particularly limited herein. For the vehicle-mounted navigation equipment, the energy information of the vehicle can be directly acquired. For mobile electronic devices such as smart phones, the state of the vehicle can be inquired in a wired or wireless vehicle connection mode, and the current remaining energy of the vehicle can be obtained.

S312: and determining the remaining mileage of the vehicle according to the remaining energy.

Specifically, the remaining energy may be combined with the unit-mileage energy consumption amount of the host vehicle to determine the remaining mileage of the host vehicle before the energy is exhausted. For example, the remaining mileage is the remaining energy/mileage energy consumption amount. Taking a gasoline car as an example, the oil consumption per hundred kilometers is 12L, and the current remaining oil amount is 9L, so that the remaining mileage of the car is 75 kilometers. If the unit mileage energy consumption does not accord with the current road condition, the calculated remaining mileage can be corrected. For the electric vehicle, the remaining mileage can be determined in combination with the unit mileage electric energy consumption. To improve accuracy, the rate of consumption of battery charge may also be determined synthetically. The consumption rate of the electric quantity is related to the use condition of the electric quantity, for example, the faster the vehicle speed is, the higher the power of the vehicle-mounted electric appliance which is turned on the vehicle is, and the lower the residual electric quantity is, the higher the consumption rate of the electric quantity is. In general, the remaining mileage can be calculated by referring to one or more factors such as vehicle speed, power consumption condition of the vehicle, road condition of the vehicle, and battery condition.

S313: determining a first to-be-selected energy supply station from the target energy supply stations according to the remaining mileage; the first candidate energy supply station is the target energy supply station of which the relative mileage with the host vehicle does not exceed the remaining mileage;

specifically, according to the GPS positioning service, the current position of the vehicle can be obtained, and then, according to the current position and the remaining mileage, the first energy supply station to be selected is determined from the target energy supply stations located within the target search range. The first energy supply station to be selected is characterized in that the first energy supply station to be selected is located in the target search range, and the distance from the first energy supply station to the vehicle is not more than the remaining distance from the vehicle.

S41: and sending the first to-be-selected energy supply station to the navigation interactive interface.

After the first to-be-selected energy supply station is sent to the navigation interactive interface, the first to-be-selected energy supply station seen by the user on the navigation interactive interface is located around the current navigation path and can reach all target energy supply stations before the energy is exhausted, so that the user can be supported to pertinently select the correct energy supply station, and the risk that the power is lost on the half road due to the fact that the user selects the energy supply station exceeding the remaining mileage is avoided.

In summary, the present embodiment provides a navigation method, in which a target energy supply station within a target search range whose distance from a host vehicle does not exceed a remaining distance is used as a first candidate energy supply station to be selected by a user, so that the host vehicle can be ensured to reach the energy supply station before energy is exhausted, and a risk of losing power on a half road is avoided.

Based on the same inventive concept of the foregoing embodiment, in another alternative embodiment, as shown in fig. 3, after the determining the target energy supply station, the navigation method further includes:

s321: and acquiring the residual energy of the vehicle.

The remaining energy is obtained in the same manner as in step S311 of the previous embodiment.

S322: and determining the remaining mileage of the vehicle and a first temporary terminal point reached by the vehicle when the remaining energy is exhausted according to the remaining energy.

The method of determining the remaining mileage is the same as the step S312 of the foregoing embodiment. And according to the remaining mileage and the current position of the vehicle, a first temporary end point of the vehicle at which the energy is exhausted can be determined. The first temporary end point may be located on the current navigation path or may be located near the current navigation path, which is not limited herein.

S323: determining a second candidate energy supply station according to the first temporary destination; the second candidate energy supply station is an energy supply station of which the relative mileage with the host vehicle does not exceed the remaining mileage.

Since the first temporary end point is the farthest distance that the vehicle can travel under the support of the remaining energy, the temporary search range can be determined according to the preset or user-specified search distance, and the second candidate energy supply station is searched in the temporary search range. The range of the search distance may be 200m to 5000 m. The temporary search range may be a sector area expanded by a preset angle with the first temporary end point as a vertex and the search distance as a radius; the mileage of the energy supply station located in the sector area from the host vehicle does not exceed the remaining mileage, so that the relative mileage of the searched second candidate energy supply station and the host vehicle can be ensured not to exceed the remaining mileage.

S42: and sending the second energy supply station to be selected to the navigation interactive interface.

Similarly, after the second candidate energy supply station is sent to the navigation interactive interface, the second candidate energy supply station seen by the user on the navigation interactive interface is an energy supply station which can be reached when the energy of the vehicle is about to be exhausted. In order to warn the user that the second energy supply station to be selected is important and cannot be missed, the second energy supply station to be selected can be displayed in a navigation interaction interface in an emphasis mode according to a first preset display method, for example, the method of changing red, flickering and the like is adopted, so that the user is prompted to go to supply when the navigation interaction interface sees the energy supply stations, and otherwise, the vehicle is subjected to the risk of losing power.

In summary, the present embodiment provides a navigation method, which displays a second candidate energy supply station on a navigation interactive interface in a targeted manner according to the remaining energy. The second candidate energy supply station is an energy supply station which is determined to be positioned near the temporary end point according to the temporary end point which can be reached by the residual energy of the vehicle and has the relative mileage with the vehicle not exceeding the residual mileage; by providing the user with an energy supply station which is still reachable nearby when the energy of the vehicle is about to be exhausted; the first is to display important energy supply stations on the navigation interactive interface in a targeted manner, but not display too many energy supply stations; and secondly, the vehicle is prevented from losing power on the half way to the energy supply station.

In order to provide an alternative energy supply station for the user in a targeted manner when the energy source is about to be exhausted, based on the same inventive concept of the foregoing embodiment, in another alternative embodiment, as shown in fig. 4, another navigation method is provided, and after the target energy supply station is determined, the navigation method further includes:

s331: and acquiring the residual energy of the vehicle.

S332: and determining the remaining mileage of the vehicle according to the remaining energy.

Specifically, the method for determining the remaining energy and the remaining mileage is the same as the foregoing embodiment, and will not be described herein again.

S333: and determining a second temporary terminal according to the remaining mileage and the second distance.

Specifically, the second temporary end point is a point before the energy source is exhausted, unlike the first temporary end point which is a point where the remaining energy source is exhausted, and the specific position is adjusted by the second distance. According to the remaining mileage and the second distance, the second temporary end point is determined by the following method: determining a second temporary end point according to the difference between the remaining mileage and the second distance, for example, if the current remaining mileage is 35km and the second distance is 5km, the second temporary end point may be the position of the vehicle after the vehicle continues to travel for 30 km; a correction factor may also be introduced to correct the calculation result, for example, the correction factor is 0.95, and the corrected second temporary end point may be the position of the vehicle after the vehicle continues to travel for 28.5 km. The second temporary end point may be located on the current navigation path, or may be located near the current navigation path, which is not limited herein; the second distance may be a preset value, such as 2km to 10km, or may be specified by a user, and is not limited herein.

S334: and determining a third candidate energy supply station within a search range with the second distance as the radius and the second temporary end point as the center.

Since the second temporary end point is not a point at which the remaining energy is exhausted, the third candidate energy supply station can be searched within a search range in which the second temporary end point and the second distance are the search radius, and the search range is wider than that of the previous solution. For example, if the remaining mileage of the vehicle is 35km and the second distance is 5km, a third candidate energy supply station within 5km of the radius is searched around the position point reached after the vehicle continues to travel for 30 km. Because the relative mileage from the vehicle does not exceed the remaining mileage of the third candidate energy supply station within the current search range, the vehicle is ensured not to lose power on the way to the third candidate energy supply station.

S43: and sending the third energy supply station to be selected to the navigation interactive interface.

Similarly, after the third candidate energy supply station is sent to the navigation interactive interface, the third candidate energy supply station seen by the user on the navigation interactive interface is an energy supply station which can be reached when the energy of the vehicle is about to be exhausted. In order to warn the user that the third energy supply station to be selected is important and cannot be missed, after the third energy supply station to be selected is sent to the navigation interactive interface, the third energy supply station to be selected is displayed in a key mode on the navigation interactive interface according to a second preset display method, for example, the user is prompted to go to supply when the navigation interactive interface sees the energy supply station, and if the navigation interactive interface sees the energy supply station, the user is prompted to go to supply, otherwise, the vehicle is subjected to the risk of losing power.

Further, after the target energy supply station and the third candidate energy supply station are sent to the navigation interactive interface, the navigation method further includes:

determining a steering position according to the navigation route and the third candidate energy supply station; the steering position is a position where the vehicle leaves the navigation route to go to the third energy replenishment station to be selected; determining a prompt position located before the steering position according to the steering position and the third distance; sending prompt information when the vehicle reaches the prompt position; and the prompt information is used for prompting the user whether to navigate to the third to-be-selected energy supply station.

Specifically, the turning position is a branching position or a deviation position between the current navigation route and a route from the current position to the third candidate energy supply station, and after the turning position is reached, the vehicle needs to leave the current navigation route to reach the third candidate energy supply station. Because the third candidate energy supply station is very important, the vehicle is likely to lose power after the vehicle misses, and therefore when the vehicle reaches the prompt position located before the steering position, prompt information can be generated and voice broadcast is carried out to remind the user whether to navigate to the third candidate energy supply station next. And after the prompt information is sent out, generating a navigation route to the third to-be-selected energy supply station according to the response of the user, such as voice indication or gesture indication. The prompting message has the following functions: firstly, the navigation method helps a user to automatically generate a navigation route to a third to-be-selected energy supply station, and avoids missing the optimal turning position; and secondly, prompting the user that the third candidate energy supply station is important and cannot be missed.

Optionally, the third distance may be a preset distance, such as 100-2000 m, or a distance specified by a user. The prompting position may be a position at a third distance from the steering position, or may be a position at a third distance from the steering position, and is not limited herein. In the case where there are a plurality of third candidate energy supply stations, the turning position may be a position at which the vehicle is driven to the third candidate energy supply station from the current navigation route at the earliest time. If the user misses the first turning position for going to the third candidate energy supply station, the subsequent prompting position can be dynamically adjusted according to the turning positions of other third candidate energy supply stations.

It should be noted that the above description takes the third candidate energy supply station as an example, and the second candidate energy supply station of the foregoing embodiment may also generate the prompt information before reaching the turning position, which is not described herein again.

In summary, the present embodiment provides a navigation method, which specifically displays a third candidate energy supply station for a driver on a navigation interactive interface, where the third candidate energy supply station determines a remaining mileage according to a remaining energy of a host vehicle, and then determines a second temporary end point of the host vehicle at a distance from the energy source before the host vehicle is exhausted according to the remaining mileage and a second distance; then determining an energy supply station near the second temporary terminal according to the second distance; the relative mileage of the third candidate energy supply station from the vehicle does not exceed the remaining mileage, so that the energy supply station which can still reach nearby when the vehicle is about to run out of energy is provided for the user; the first is to display important energy supply stations on the navigation interactive interface in a targeted manner, but not display too many energy supply stations; and secondly, the vehicle is prevented from losing power on the half way to the energy supply station.
