Abstract

A calculation apparatus (100) calculates a correction value for calculating an estimated consumption amount. An input unit (101) receives an input of an energy amount supplied to a mobile body. An estimated consumption amount calculation unit (102) calculates an energy amount (estimated consumption amount) that the mobile body consumes when moving in a predetermined section. An acquisition unit (103) acquires an energy amount (actual measurement consumption amount) that the mobile body has actually consumed during movement in the predetermined section. A storage unit (104) stores ratios (hereafter referred to as "speed band ratios") dividing a time or distance required for moving in the predetermined section for each of a plurality of speed bands of the mobile body. A correction amount calculation unit (105), on the basis of a difference between the actual measurement consumption amount and the estimated consumption amount, and the ratios for each speed band of the mobile body, calculates a correction value for the calculation of the estimated consumption amount by the estimated consumption amount calculation unit (102).

Storage part 104 is stored according to a plurality of velocity bands of moving body and is divided in predetermined interval and moves the required ratio that needs the time or need distance (below, be called " ratio of velocity band ").Specifically, for example velocity band is being divided into the 1st velocity band, the 2nd velocity band during this 2 stages, moving body moves at predetermined interval needs 100 hours, when moving body has moved wherein 60 hours in the 1st velocity band after, storage part 104 is stored as 60 with the ratio of the 1st velocity band, and the ratio of the 2nd velocity band is stored as 40(=100-60).

That is, the ratio of the 1st velocity band is 60 to mean, makes the 1st velocity band for less than speed per hour 50km, and making the 2nd velocity band is in the above situation of speed per hour 50km, and moving body is all 60% with the time that needs that the speed per hour less than speed per hour 50km moves.Also the velocity band of moving body can be divided into 3 more than the stage.

In addition, storage part 104 storages are used for the threshold value of the velocity band of division moving body.Specifically, storage part 104 for example when velocity band is divided into 2 stages, is stored the speed on the 1st velocity band, the 2nd velocity band border, as the threshold value of the velocity band that is used for the division moving body.Specifically, make the 1st velocity band for less than speed per hour 50km, making the 2nd velocity band is speed per hour 50km when above, and storage part 104 storage speed per hour 50km are as the threshold value of the velocity band that is used for the division moving body.Storage part 104 also can be stored the 1st velocity band, the 2nd velocity band itself.

Correcting value calculating part 105 calculates the compensation value of estimating that consumption calculating part 102 calculates when estimating consumption according to the ratio of actual measurement consumption with the velocity band of the difference of estimating consumption and each moving body.Specifically, correcting value calculating part 105 calculates actual measurement consumption and the difference of estimating consumption.This difference is to proofread and correct the correcting value of estimating consumption.Then, correcting value calculating part 105 is cut apart actual measurement consumption and the difference of estimating consumption according to every kind of reason, calculates the correcting value of estimating consumption according to every kind of reason.Then, correcting value calculating part 105 comes calculated correction value according to the correcting value of the estimation consumption that calculates according to every kind of reason.

More particularly, for example, correcting value calculating part 105 at first calculates the 1st correcting value that standby consumption and acceleration consumption are proofreaied and correct and the 2nd correcting value that the consumption that travels is proofreaied and correct.Then, correcting value calculating part 105 is proofreaied and correct the estimation consumption according to this correcting value according to every kind of reason, estimates that according to these consumption comes calculated correction value according to every kind of reason.At this moment, correcting value calculating part 105 can be distinguished the correcting value of calculation correction standby consumption and proofread and correct the correcting value that accelerates consumption.In addition, correcting value calculating part 105 also can adopt the acceleration/accel of moving body to come the calculation correction amount.

In addition, correcting value calculating part 105 for example can adopt the ratio of the velocity band of the moving body low speed in the velocity band to calculate the 1st correcting value.The velocity band of moving body low speed for example can be the velocity band of the dead slow in a plurality of velocity bands, also can be the velocity band beyond the velocity band the most at a high speed.

In addition, correcting value calculating part 105 also can adopt the velocity band of the dead slow in a plurality of velocity bands to calculate the 1st correcting value to the ratio in predetermined speed zone velocity band being divided into 3 stages when above.Specifically, correcting value calculating part 105 for example can calculate the 1st correcting value according to the ratio of a plurality of velocity bands below the legal limit that is configured to Ordinary road.

More particularly, correcting value calculating part 105 is whenever to moving body supply energy the time, the actual measurement consumption that calculating is obtained by obtaining section 103 (energy supply amount) with by the difference of estimating the estimation consumption that consumption calculating part 102 calculates, come the calculation correction amount according to this difference.Then, correcting value calculating part 105 recomputates compensation value according to the correcting value that calculates.

In addition, correcting value calculating part 105 changes the information as weight that is stored in the storage part 104 whenever to moving body supply energy the time.Specifically, correcting value calculating part 105 will deduct predetermined subtraction value and will be altered to close to 0% when calculated correction value as the information of weight.In addition, correcting value calculating part 105 also can according to actual measurement consumption and the difference of estimating consumption, will add predetermined addition value or deduct predetermined subtraction value as the information of weight.

Then, the correction value processing of computer device 100 described.Fig. 2 is the diagram of circuit that the order that the correction value of computer device processes is shown.In the diagram of circuit of Fig. 2, computer device 100 utilizes estimates that consumption calculating part 102 calculates the estimation consumption (step S201) of time per unit.At this moment, computer device 100 calculates the estimation consumption according to the catabiotic every kind of reason of moving body.

Then, computer device 100 has judged whether to the moving body supply energy (step S202), before to moving body supply energy, carries out processing (the step S202: the loop of "No") of step S201 in the predetermined moment.To the moving body supply during energy (step S202: be), computer device 100 utilizes obtaining section 103 to obtain energy supply amount (actual measurement consumption) (step S203).At this moment, computer device 100 utilizes the estimation consumption of estimating 102 pairs of time per units of consumption calculating part to add up, and calculates the estimation consumption in the predetermined interval.

Then, computer device 100 utilizes the difference (step S204) of the estimation consumption in correcting value calculating part 105 calculating energy increments and the predetermined interval.Then, computer device 100 calculates the correcting value (step S205) of estimating consumption according to every kind of reason.That is, computer device 100 is divided energy supply amount and the difference of estimating consumption according to a plurality of velocity bands of moving body according to every kind of reason.

Then, computer device 100 adopts the correcting value of the estimation consumption that is calculated according to every kind of reason by correcting value calculating part 105, calculates according to every kind of reason and estimates that consumption calculating part 102 calculates the compensation value (step S206) when estimating consumption.Then, computer device 100 is stored compensation value (step S207), the processing of process ends figure in storage part 104.

As described above, the energy (actual measurement consumption) of the computer device 100 of embodiment user's input during according to moving body supply energy, the compensation value when estimating consumption to calculating calculates.In more detail, computer device 100 is according to estimating the ratio of consumption with the velocity band of the difference of surveying consumption and moving body, and the compensation value when estimating consumption to calculating calculates.Like this, computer device 100 calculates the compensation value of the clear and definite benchmark of the conduct correction of estimating consumption and the deviation of surveying consumption, thereby can correctly calculate the estimation consumption according to the energy supply amount of reality.In addition, the user only be input to the energy supply amount of the reality of moving body supply, thereby do not need self to calculate and estimate consumption, and can free from inputting by user's self judgement to proofread and correct the such troublesome operation of the correcting value of estimating consumption.

In addition, computer device 100 is divided into 3 more than the stage with the velocity band of moving body, and the compensation value when estimating consumption to calculating calculates.Therefore, according to computer device 100, the condition in the time of can carrying out calculated correction value is in more detail set, thereby can make the deviation of estimating between consumption and the actual measurement consumption less.

In addition, also according to the acceleration/accel of moving body, the compensation value when estimating consumption to calculating calculates computer device 100.Therefore, according to computer device 100, can come calculated correction value according to user's acceleration and deceleration regime, thereby can improve and calculate the precision of estimating consumption.

In addition, computer device 100 will deduct predetermined subtraction value and will be altered to close to 0% when calculated correction value as the information of weight.Therefore, according to computer device 100, whenever to moving body supply energy the time, the compensation value that calculated by computer device 100 is restrained to the value that makes the difference of estimating consumption and energy supply amount close to 0.

Then, homing advice 300 adopts above-mentioned formula (4), calculates the correction amount delta K1 of standby consumption, the correction amount delta K2 that accelerates consumption and the correction amount delta K3(step S609 of the consumption that travels).That is, homing advice 300 is allocated to the difference of oil mass and fuel discharge Σ Fc according to the 1st velocity band, the 2nd velocity band of vehicle according to every kind of reason of vehicle consume fuel.

Then, homing advice 300 adopts above-mentioned formula (5) to recomputate standby consumption Σ K1, accelerates consumption Σ K2 and the consumption Σ K3(step S610 that travels).Then, homing advice 300 adopts above-mentioned formula (6) to recomputate the 1st coefficient of correction H1, the 2nd coefficient of correction H2(step S611).Then, 300 pairs of memory storages of homing advice write the 1st coefficient of correction H1, the 2nd coefficient of correction H2(step S612), the processing of process ends figure.

(the weight change of homing advice 300 one of is processed)

One example of the weight change processing of homing advice 300 then, is described.Fig. 7 is the diagram of circuit that the order that the weight change of homing advice processes is shown.In the diagram of circuit of Fig. 7, homing advice 300 obtain the user via input equipment 311 input to vehicle to oil mass (step S701).Step S701 for example is equivalent to above-mentioned step S603.

Then, homing advice 300 is read the weight α (step S702) that is stored in the memory storage.Then, homing advice 300 adopts above-mentioned formula (6) to recomputate the 1st coefficient of correction H1, the 2nd coefficient of correction H2(step S703).

Then, homing advice 300 judges whether the 2nd coefficient of correction H2 that calculates is in (step S704) in the proper range in step S703.Specifically, homing advice 300 for example judges whether the 2nd coefficient of correction H2 becomes negative value.More particularly, homing advice 300 for example judges whether the 2nd coefficient of correction H2 is in more than 0.1 in the scope below 10.

When the 2nd coefficient of correction H2 is not in proper range (step S704: no), homing advice 300 deducts predetermined subtraction value (step S705) with weight α.On the other hand, when the 2nd coefficient of correction H2 is in the proper range (step S704: be), does not carry out the processing of step S705 and enter step S706.Then, 300 pairs of memory storages of homing advice write weight α (step S706), the processing of process ends figure.

(weight in the homing advice 300 change processing two)

Another example of the weight change processing of homing advice 300 then, is described.Fig. 8 is the diagram of circuit that the order of another example that the weight change of homing advice processes is shown.In the diagram of circuit of Fig. 8, homing advice 300 obtain the user via input equipment 311 input to vehicle to oil mass (step S801).Step S801 for example is equivalent to above-mentioned step S603.

Then, homing advice 300 is read the weight α (step S802) that is stored in the memory storage.Then, homing advice 300 calculated fuel consumption Σ Fc_org and the difference delta Fc(step S803 that gives oil mass).The method of calculating of difference delta Fc is for example identical with one of correction factor calculation formula.

Then, homing advice 300 judge fuel discharge Σ Fc_org with to the difference delta Fc of oil mass predefined threshold value above (step S804) whether.When difference delta Fc is predefined threshold value when above (step S804: be), homing advice 300 adds predetermined addition value (step S805) with weight α.

On the other hand, when difference delta Fc is not predefined threshold value when above (step S804: no), homing advice 300 deducts predetermined subtraction value (step S806) with weight α.Then, 300 pairs of memory storages of homing advice write weight α (step S807), the processing of process ends figure.

Weight change shown in above-mentioned Fig. 7,8 is processed as mentioned above and can be carried out in the moment of the step S603 that carries out correction factor calculation processing shown in Figure 6, also can (after the step S612) carry out after correction factor calculation processing shown in Figure 6 finishes.

In addition, carrying out the weight change shown in Fig. 7,8 when inputing to oil mass (to the vehicle oil supply time) processes.In addition,, repeatedly carry out the weight change and process before the value convergence of fuel discharge Σ Fc_org and the difference delta Fc=0 that gives oil mass at the 1st coefficient of correction H1, the 2nd coefficient of correction H2.Weight α≤0 o'clock in step S705 or step S806, homing advice 300 returns to as 100% of initial value weight.

(example of the telltale 313 of homing advice 300)

Fig. 9 is the instruction diagram of display frame that the computer device of embodiment is shown.The display frame 900(telltale 313 of homing advice 300) possesses the comprehensive bunkerage display part 910 that shows comprehensive bunkerage, the correction fuel expense display part (fuel-economizing state) 920 that shows the comprehensive bunkerage after proofreading and correct and the input part 930 that inputs to oil mass.

Specifically, comprehensive bunkerage display part 910 shows the fuel discharge Σ Fc that adopts above-mentioned formula (2) to calculate, as comprehensive bunkerage.When inputing to oil mass via input part 930, correction fuel consumption Σ Fc.Correction fuel expense display part 920 is presented at the correction fuel expense 921 that calculated during oil supply last time and the correction fuel expense 922 that calculates when this oil supply.

Input part 930 possess accept to be used for increase (+) or reduce (-) to the operated key 931 of user's operation of oil mass and be shown to oil mass to oil mass display part 932.Utilize the touch panel mode to realize input part 930.When correcting value change+1 or-1, the correction fuel expense increases or reduces approximately 1%.

As described above, according to homing advice 300, according to the user input when the oil supply to oil mass (actual measurement consumption), the coefficient of correction during to calculated fuel consumption calculates.In more detail, the ratio of the difference of homing advice 300 based on fuel consumptions and actual measurement consumption and the velocity band of vehicle, the coefficient of correction during to calculated fuel consumption calculates.Like this, computer device 100 comes the conduct of calculated fuel consumption to proofread and correct coefficient of correction with the clear and definite benchmark of surveying the deviation between the consumption according to reality to oil mass, thereby calculated fuel consumption correctly.In addition, the user only be input to the reality of vehicle oil supply to oil mass, thereby do not need self calculated fuel consumption, and can from the such troublesome operation of the correcting value of inputting the correction fuel consumption by user's self judgement, free.

In addition, homing advice 300 is divided into 3 more than the stage with the velocity band of vehicle, and the coefficient of correction during to calculated fuel consumption calculates.Therefore, according to homing advice 300, the condition in the time of can carrying out the calculation correction coefficient is more subtly set, thereby can make the deviation between fuel discharge and the actual measurement consumption less.

In addition, also the coefficient of correction during to calculated fuel consumption calculates homing advice 300 according to the acceleration/accel of vehicle.Therefore, according to homing advice 300, can come the calculation correction coefficient according to user's acceleration and deceleration regime, thereby can improve the precision of calculated fuel consumption.

In addition, when the calculation correction coefficient, homing advice 300 will deduct predetermined subtraction value and be altered to close to 0% as the information of weight.Therefore, according to homing advice 300, whenever to vehicle supply energy the time, can make the coefficient of correction that calculated by homing advice 300 to make fuel discharge with to the difference of oil mass close to 0 value convergence.
