For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.
Set forth in the following description a lot of details so that fully understand the present invention, implement but the present invention can also adopt other to be different from alternate manner described here, so the present invention has not been subjected to the restriction of following public specific embodiment.
Just as described in the background section, prior art all is just can initiatively send to refuel to a certain extent the time less at the fr of vehicle to remind, for fear of the situation that the fr deficiency occurs, vehicle user can only often remove to check the fr of fuel tank device demonstration, thereby when refuel according to self micro-judgment, caused refueling the complexity that the inaccuracy judged and vehicle user drive.
For fear of defects, the invention provides a kind of group refueling based reminding method based on path planning, by obtaining the path planning of vehicle, the magnitude relationship of the current oil mass of the required oil mass in alternative plans path and vehicle, when current oil mass during less than required oil mass, vehicle is carried out the active oiling to be reminded, change prior art and only do not had soon the oily situation of reminding of just refueling at vehicle, guarantee that the user is carrying out in the driving process according to path planning, need not to worry the problem of low on fuel, thereby when improving the oiling judgment accuracy, can provide better service for vehicle user, improve the experience effect of navigation user.
Be elaborated below in conjunction with accompanying drawing.
Referring to shown in Figure 1, the group refueling based reminding method based on path planning that the present embodiment provides comprises:
Step S1 obtains the path planning of vehicle, obtains the distance of described path planning;
Step S2, the oil consumption of obtaining described vehicle obtains the required oil mass of described path planning;
Step S3 extracts the current oil mass of described vehicle, and the size of more described required oil mass and described current oil mass when described current oil mass during less than described required oil mass, is refueled prompting to described vehicle;
Step S4, described vehicle is refueled remind after, according to described path planning, carry out the fuel station information search, and the fuel station information prompting be provided.
Vehicle comprises onboard navigation system described in the present embodiment, and described vehicle communicates by onboard navigation system and server end or network-side.
Execution in step S1 at first, path planning is carried out according to described current location and destination in the current location and the destination that obtain vehicle, obtains the path planning of vehicle, and then extracts the distance of path planning from described path planning.Described distance be vehicle according to path planning from current location travel to the destination process apart from sum.
The current location of described vehicle can by vehicle user oneself input, also can be provided by the locating device of vehicle; The destination of described vehicle can be inputted by vehicle user oneself.
After determining the current location and destination of vehicle, carry out path planning and have following dual mode at least: a kind of is to adopt any one onboard navigation system to calculate path planning between vehicle current location and the destination at vehicle termination; Another kind is that the current location of vehicle and destination are sent to server end, calculates path planning between vehicle current location and the destination by server end, and path planning is passed to vehicle termination by server end.Preferably, described path planning is finished at vehicle termination, thereby the path planning that obtains more meets the actual conditions of described vehicle.
After obtaining the path planning of vehicle, just can from path planning, directly extract the distance of path planning.
Further, the information such as distance of the current location of described vehicle, destination, path planning, path planning can also be carried out the picture and text demonstration or/and voice broadcast at vehicle.
Then execution in step S2, the oil consumption of obtaining described vehicle obtains the required oil mass of described path planning.
The oil consumption of vehicle described in the present embodiment refers to the amount of fuel of 100 kilometers consumption of Vehicle Driving Cycle.Need to prove, can also adopt in other embodiments of the invention the oil consumption of other parameter characterization vehicles, as: amount of fuel of 1 kilometer consumption of Vehicle Driving Cycle etc.
Particularly, the amount of fuel of the 100 kilometers consumption of travelling that vehicle manufacturer provides can be directly adopted in the oil consumption of described vehicle, in the past the travelled average fuel amount of 100 kilometers consumption of the vehicle that also can adopt this vehicle oil consumption record in the past to calculate can also adopt the amount of fuel of the 100 kilometers consumption of travelling that other vehicles of same model provide.
After the distance of the oil consumption of learning vehicle and path planning, the distance of oil consumption and path planning multiplied each other just can obtain the required oil mass of path planning.Need to prove, when oil consumption referred to the amount of fuel of 100 kilometers consumption of vehicle travel, the distance of described path planning also should be with 100 kilometers as unit.As: the oil consumption of vehicle is 8 liters/hundred kilometers, and the distance of path planning is 1,000 kilometers, and the required oil mass of the path planning that travelled so is 80 liters.Further, in the driving process of vehicle, there are many factors can cause the difference of oil consumption.As: the flatness of the degree of crook of road, the gradient of road, road and traffic congestion degree etc.In general, gather in the process of map datum at GPS, can be according to the data of the various roads that collects, such as information such as the degree of crook in the road, the gradient, road evenness, be saved on car-mounted terminal or the server, described traffic congestion degree can be obtained from traffic control system by network in real time.Therefore when comprising above-mentioned factor in the path planning, can obtain respectively oil consumption corresponding under the above-mentioned different road conditions, when calculating the required oil mass of path planning, again addition after oil consumption corresponding under road distance under the different road conditions and this road conditions multiplied each other, rather than the distance of path planning and the oil consumption of fixed value are multiplied each other, thereby can obtain more accurate required oil mass, finally guarantee the accuracy that follow-up oiling is reminded.
Then execution in step S3 extracts the current oil mass of described vehicle, and the size of more described required oil mass and described current oil mass when described current oil mass during less than described required oil mass, is refueled prompting to described vehicle.
The current oil mass of described vehicle can directly read in the fuel gauge by vehicle, and the current oil mass of described vehicle is exactly the fr of vehicle.
After the current oil mass of learning vehicle and required oil mass, in order to judge whether to refuel prompting, need the size of more required oil mass and current oil mass, it comprises following several situation:
1) when current oil mass during less than required oil mass, the current oil mass of vehicle can not make Vehicle Driving Cycle to the destination, therefore need to refuel prompting.
2) when current oil mass equals required oil mass, although the current oil mass of vehicle can make Vehicle Driving Cycle to the destination, but Vehicle Driving Cycle just is in the state without oil during to the destination, and this also is not allow situation about occurring in actual applications, therefore also needs to refuel prompting this moment.
3) when current oil mass greater than required oil mass but the difference of current oil mass and required oil mass during less than first threshold, arrive follow-up behind the destination and normally travel in order not affect vehicle, also need to refuel prompting.
Wherein, described first threshold can be oil mass corresponding to Vehicle Driving Cycle preset distance (as: 10 kilometers), also can be oil mass corresponding to the predetermined factor (as: 1/10th) of vehicle fuel tank capacity, can also for vehicle travels from the destination to oil mass corresponding to nearest refuelling station, distance destination, can also travel from the destination to oil mass corresponding to the most cheap refuelling station of price, distance destination etc. for vehicle.
Particularly, described first threshold can be carried out different set according to the different selection of user, also can be by the vehicle automatic setting.
4) when current oil mass greater than required oil mass, and the difference of current oil mass and required oil mass is during more than or equal to first threshold, do not need to refuel prompting.
In sum, in the situation of difference less than first threshold of current oil mass and required oil mass, all need to refuel prompting.
Described oiling is reminded and can be comprised: refuel warning by literal, sound or light.As: the display device by vehicle shows similar literal such as " this have refueled ", reports similar voice such as " this have refueled " by the stereo set of vehicle, the warning message of the expression " this has refueled " such as the color by warning lamp, flashing mode.Concrete oiling type of alarm can be set according to user's selection, also can be by the vehicle automatic setting.
The described oiling reminded and can also be comprised: calculate and show the need volume read-out of described vehicle, described volume read-out and the described current oil mass sum of needing is more than or equal to described required oil mass and first threshold sum.Simultaneously, according to vehicle fuel tankage and current oil mass, but can also calculate the volume read-out of described vehicle; But according to described volume read-out and the described comparative result that needs the volume read-out size, carry out the fuel station information search.
The described volume read-out that needs refers to for vehicle is arrived at the destination from current location, and arrives that the fr of vehicle is first threshold behind the destination, the volume read-out that vehicle is required.
But described volume read-out refers to the poor of vehicle fuel tankage and current oil mass, but the i.e. maximal value of the current volume read-out of vehicle.
But described need volume read-out may greater than, be equal to or less than described volume read-out.When but described need volume read-out was less than or equal to described volume read-out, expression realized this path planning, once refuels to get final product; But when needing volume read-out greater than described volume read-out, expression realizes this path planning, needs at least to carry out twice or twice above oiling when described.
Last execution in step S4, described vehicle is refueled remind after, according to described path planning, carry out the fuel station information search, and the fuel station information prompting be provided.
Describedly carry out fuel station information search and can trigger based on the searching request that the user sends, as: after receiving the oiling prompting that vehicle sends, the user sends the request of seeking of carrying out fuel station information to vehicle, after vehicle is received this searching request, just can carry out the fuel station information search.Describedly carry out fuel station information search and also can trigger based on refueling the event of reminding, as: vehicle send to the user refuel remind after, vehicle carries out the fuel station information search immediately, selects and need not the user.Above-mentioned two kinds of triggering modes can therefrom select it to preserve in the lump setting by the user, to avoid carrying out repetitive operation in follow-up use.
Also comprise the required fuel oil type that extracts described vehicle described carrying out before the fuel station information search.The required fuel oil type of different vehicle may be different, and the fuel oil type that different refuelling stations provide also may be different.
Described fuel station information comprises the positional information of refuelling station and the fuel oil type information that the refuelling station provides at least.Preferably, described fuel station information can also comprise one or more in the review information of quality, refuelling station of price, the required fuel oil type of vehicle of the required fuel oil type of vehicle, thereby provide the position of the required fuel oil type of vehicle and refuelling station to be positioned under the condition of path planning highway section certain distance scope in the satisfied refuelling station that searches out, therefrom further select minimum, the required fuel oil quality of required fuel price preferably or serve best refuelling station, for the user provides more fully information and better service.The refuelling station that searches out should be arranged in or be close to the highway section of path planning.
When automobile storage contains fuel station information, describedly carry out fuel station information search and can finish at vehicle termination.Preferably, described carry out fuel station information search and be triggered after, finish the fuel station information search and the fuel station information of search is sent to described vehicle by server end or network-side, thereby can take full advantage of the abundanter information resources of service end or network-side, and not increase the information processing burden of vehicle.
Further, described vehicle termination, service end or network-side can be in real time, regularly or fuel station information carry out renewal or the maintenance of fuel station information when changing, to guarantee the accuracy of fuel station information search.
But below when needing volume read-out to be less than or equal to described volume read-out, carry out the process that fuel station information is searched for when described with the explanation of four specific embodiments.
As first specific embodiment, described vehicle is refueled remind after, can search out path planning middle distance vehicle current location recently and the refuelling station of the required fuel oil type of vehicle is provided, will go to the refuelling station of refueling as vehicle.Refuelling station in the path planning can be arranged in the vehicle path planning need through the highway section, also can be arranged in the vehicle path planning need through highway section certain distance scope, as: need in the refuelling station that searches out and the vehicle path planning through the minimum distance in highway section be 200 meters.
As second specific embodiment, described vehicle is refueled remind after, can search out a plurality of refuelling stations that the required fuel oil type of vehicle is provided in the corresponding distance of the current oil mass of vehicle in the path planning, based on user's selection information, from described a plurality of refuelling stations, select one will go to the refuelling station of refueling as vehicle.The corresponding distance of the current oil mass of described vehicle refers to the distance that the current oil mass of vehicle can be travelled.
As the 3rd specific embodiment, described vehicle is refueled remind after, can search out provide the required fuel oil type of vehicle in the corresponding distance of current oil mass of vehicle in the path planning and fuel price is minimum or fuel oil quality preferably or serve best refuelling station, will go to the refuelling station of refueling as vehicle.
As the 4th specific embodiment, described vehicle is refueled remind after, can search out all refuelling stations that the required fuel oil type of vehicle is provided in the corresponding distance of the current oil mass of vehicle in the path planning, with wherein fuel price is minimum, fuel oil quality is best, three best refuelling stations of service extract respectively, based on user's selection information, from described three refuelling stations, select one will go to the refuelling station of refueling as vehicle.
Searching out after vehicle will go to the refuelling station of refueling, and providing the fuel station information prompting to the user, described prompting can be one or more in picture and text, sound, the light; And then based on user's selection information, onboard navigation system just can be carried out navigation from current location to the refuelling station of refueling for vehicle.
When but described need volume read-out is less than or equal to described volume read-out, directly carries out refuelling station's search and get final product.Wherein, but vehicle should need volume read-out and be less than or equal to described volume read-out more than or equal to described at the actual volume read-out of refuelling station.In the practical application, but the actual volume read-out of vehicle equals described volume read-out, namely when refueling the fuel tank of described vehicle is filled it up with, thereby can be reduced the number of times of group refueling, prolongs the serviceable life of vehicle.
But the below when needing volume read-out greater than described volume read-out, carries out the process that fuel station information is searched for when described with the explanation of specific embodiment.
As the 5th specific embodiment, described vehicle is refueled remind after, can search out all of the required fuel oil type of vehicle refuelling stations are provided in the path planning, take current location as the first departure place, in distance corresponding to the current oil mass of vehicle, from described all refuelling stations, select the first refuelling station; Be in distance corresponding to vehicle fuel tankage, to select the second refuelling station in the second departure place take the first refuelling station; Be successively new departure place take last refuelling station, in distance corresponding to vehicle fuel tankage, select next refuelling station, until so that vehicle arrives the destination.Described selection refuelling station can be based on user's selection information, also can automatically select the minimum refuelling station of fuel price in the described distance, the best refuelling station of service in the described distance can also be automatically selected, the best refuelling station of fuel oil quality in the described distance can also be automatically selected.Distance corresponding to described vehicle fuel tankage refers to that vehicle fills it up with the distance that can travel behind the fuel tank.In above-described embodiment, require each the oiling all vehicle fuel tank to be filled it up with.Need to prove, for fear of the number of times that increases group refueling, to arriving range difference between two adjacent in the path, destination refuelling stations more than or equal to setpoint distance.For example: 7/8ths or 4/5ths oil mass that described setpoint distance can corresponding vehicle fuel tankage, after namely vehicle was filled it up with fuel tank and travelled, the fr in vehicle just refueled less than 1/8th or five/for the moment next time at least.
