(example of the telltale 313 of homing advice 300)
Fig. 9 is the instruction diagram of the display frame of the computer device that embodiment is shown.The display frame 900 (telltale 313) of homing advice 300 possesses the integrated fuel showing integrated fuel expense and takes display part 910, shows correction fuel expense display part (fuel-economizing state) 920 that the integrated fuel after correcting takes and the input part 930 inputing to oil mass.
Specifically, integrated fuel expense display part 910 shows the fuel discharge Σ Fc adopting above-mentioned formula (2) to calculate, and takes as integrated fuel.Whenever inputing to oil mass via input part 930, correction fuel consumption Σ Fc.The correction fuel expense 921 that correction fuel expense display part 920 calculates when being presented at oil supply last time and the correction fuel expense 922 calculated when this oil supply.
Input part 930 possess accept for increase (+) or reduce (-) to the operated key 931 of the user operation of oil mass and be shown to oil mass give oil mass display part 932.Utilize touch panel mode to realize input part 930.When correcting value changes+1 or-1, correction fuel takes to be increased or reduces about 1%.
As described above, according to homing advice 300, input when oil supply according to user to oil mass (actual measurement consumption), coefficient of correction during calculated fuel consumption is calculated.In more detail, homing advice 300 based on fuel consumption and the ratio of surveying the difference of consumption and the velocity band of vehicle, calculate coefficient of correction during calculated fuel consumption.Like this, computer device 100 carrys out the coefficient of correction of clear and definite benchmark as the deviation corrected between actual measurement consumption of calculated fuel consumption to oil mass according to reality, thus can correctly calculated fuel consumption.In addition, user be only input to the reality of vehicle oil supply to oil mass, thus do not need self calculated fuel consumption, and free the such troublesome operation of the correcting value that can input correction fuel consumption from the judgement by user self.
In addition, the velocity band of vehicle is divided into more than 3 stages by homing advice 300, calculates coefficient of correction during calculated fuel consumption.Therefore, according to homing advice 300, condition setting during calculation correction coefficient can be carried out more subtly, the deviation between fuel discharge and actual measurement consumption thus can be made less.
In addition, homing advice 300 also calculates coefficient of correction during calculated fuel consumption according to the acceleration/accel of vehicle.Therefore, according to homing advice 300, calculation correction coefficient can be carried out according to the acceleration of user and deceleration regime, thus can improve the precision of calculated fuel consumption.
In addition, whenever calculation correction coefficient, the information as weight is deducted predetermined subtraction value and is altered to close to 0% by homing advice 300.Therefore, according to homing advice 300, whenever to vehicle supply energy, 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 restrain.
In addition, by being performed pre-prepd program to realize the method for calculating illustrated in the present embodiment by the computing machine such as Personal Computer or workstation.This program is recorded in the recording medium of the embodied on computer readable such as hard disk, floppy disk, CD-ROM, MO, DVD, by reading out this program of execution by computing machine from recording medium.In addition, this program also can be can via the transmission medium of the Web Publishing such as internet.
