Detailed description of the invention
Describing the present invention below according to accompanying drawing, it is a kind of preferred embodiment in numerous embodiments of the present invention.
In a preferred embodiment, a kind of course continuation mileage (DTE) optimizes system-computed method and displaying scheme, the meter of optimization
Calculation method includes: combination instrument processor, combination instrument character display, fuel sensor, ABS control unit and start
Machine control unit.Combination instrument processor receives the amount of fuel of the current mailbox that fuel sensor gathers by rigid line, passes through CAN
Line receives the vehicle speed value that ABS control unit sends, and is received the instant spray of the electromotor that control unit of engine processes by CAN line
Oil mass (fuel consumption), calculates the average consumprion of the previous segment distance of the surplus sum of the mileage of vehicle traveling, current fuel,
Then estimate out remaining amount of fuel can continue to travel how many distances according to Fuel Oil Remaining and average consumprion, finally by combination instrument
Table character display shows.Current fuel surplus is to deduct control unit of engine by the amount of fuel detected after refueling
Amount of fuel that the instant distributive value of electromotor processed is drawn, and this fr sampled with fuel sensor in real time
Value is compared calibration.Average consumprion is that the distributive value adding up distance (such as 30km) electromotor the last period is divided by distance the last period
Meansigma methods, and this average consumprion with the form of storehouse with the speed of every kilometer (often increases by 1 kilometer, will lose the 1st kilometer
Data) be updated.By the invention course continuation mileage algorithm after this optimization, can be in vehicle travel process, can be true and real
Time ground reflect the relation of current oil mass and mileage, more can indicate current oil mass can continue traveling how many distances to client exactly,
There is accurate, real-time, the intelligent and advantage of hommization.
The algorithm optimized and displaying scheme:
Optimize the computing formula (Fig. 2) of DTE
1, definition:
L: after oiling or accumulator power on after the oil mass that detects
△ L: add oil every time or accumulator re-power after fuel oil total flow
△LnIt is the data that send of control unit of engine, the fuel consumption of n-th kilometer
50 (km) in formula can be set according to different vehicles, its objective is to guarantee to give warning in advance, when the value of course continuation mileage
Less than then reminding driver during 50km
2, AFC chooses
Such as choose the average fuel consumption of front 30km
After combination instrument processor need to remember the fuel consumption of front 30km every kilometer, and vehicle often travels 1 kilometer, processor such as storehouse shape
Formula, loses fuel consumption, the fuel consumption of access the 31st kilometer of the 1st kilometer.As shown in Figure 2
3, the compensation operation of L
Instrument from fuel sensor actual samples to oil mass be designated as LReal, Fuel Oil Remaining is:
1. as L-△ Ln-LRealK=[(L-△ Ln-L during ＞ 1LReal)+m] (m is calibration coefficient to/m, and value is according to test and comprehensive road
The numerical value that condition fuel consumption per hundred kilometers is equivalent)
2. as | L-△ Ln-LReal| k=1 during≤1L
3. as L-△ Ln-LRealK=0.8 during ＜-1L
4, the compensation of display
DTEnShow value: currently displaying value
DTEn+1Show value: DTEnValue of calculation
As Shu DTEnValue of calculation-DTEnShow value Shu≤10km
DTEn+1Show value=DTEnValue of calculation
As Shu DTEnValue of calculation-DTEnShow value Shu ＞ 10km
DTEn+1Show value=DTEnShow value ± 10km
The DTE value of display is required for comparing with show value before, if (comprised within 10km with current value of calculation i.e. every time
10km), then directly display current value of calculation when refreshing, if it exceeds 10km, increase on the basis of show value before or
Reduce 10km and show (Fig. 4)

Before we choose optimization (Fig. 5) and optimize after (Fig. 6) algorithm import combination instrument carry out real vehicle checking, the row of registration of vehicle
Sail the DTE video data of mileage and combination instrument, and draw out curve, from actual tests curve it follows that
1) problem that course continuation mileage fluctuation is excessive cannot be evaded；
2) display does not processes, and mutation problems occurs；
3) excessive with actual deviation, directive significance is not good enough.
And the algorithm after optimizing reduces error, actual data are more fitted reality, are more prone to allow client accept.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements and is not subject to the restrictions described above,
As long as have employed method design and the various improvement that carry out of technical scheme of the present invention, or the most improved directly apply to other occasion
, all within protection scope of the present invention.
