Fig. 2 diagrammatically illustrates the flow chart of the vehicle-state determination methods of the embodiment of the present invention, as shown in Fig. 2 vehicle
State judging method includes：
S1, calculates the TR speed ratio of vehicle.
Speed changer is the mechanism for changing rotating speed and torque from engine, and it can be fixed or stepping changes output shaft
With the gearratio of input shaft, its gearbox that is otherwise known as.Speed changer includes the driving gear and driven gear of the different numbers of teeth, leads to
Cross and matched different driving gear and driven gear, so that change automobile gear level, wherein, TR speed ratio refers to
The ratio between number of teeth of driven gear and driving gear.
However, driven gear cannot go to obtain in real time with the number of teeth of driving gear, and automobile gear level information also cannot
Obtained from the can buses of vehicle.The present invention first has to obtain the speed v of vehicle, wheel half to obtain TR speed ratio
Footpath r, engine speed n and axle ratio io, further according to above- mentioned information, the TR speed that vehicle is calculated in real time compares ig：
In embodiments of the present invention, speed v can be obtained from can buses, and radius of wheel r can be calculated according to tire specification
Obtain (by taking common tire specification 205/55R16 as an example：205 represent that tire cross-sectional width is 205 millimeters, and 55 represent that tire is high
Ratio wide represents tyre equatorial tire construction for 55%, R, and 16 represent a diameter of 16 inches of tyre rims, and 1 inch is approximately equal to 25.4
Millimeter, therefore tire overall diameter computational methods are：205 × 55% × 2+16 × 25.4=631.9 millimeters, it is necessary to radius then divided by
2), engine speed n can be obtained from the can buses of vehicle interior, and axle ratio io refers to the rear axle ratio of vehicle chassis,
Various platforms (such as " family of truck ") acquisition can be inquired about according to vehicle from the market.
It should be noted that above-mentioned calculation must calculate effective when making a concerted effort for 0 (vehicle is at the uniform velocity travelled), car
Right and wrong at the uniform velocity state when acceleration and deceleration, so vehicle is under acceleration or deceleration state, the TR speed ratio for calculating
Ig is invalid.Therefore, the embodiment of the present invention also needs to judge that vehicle is currently after the TR speed for calculating is than ig
It is no at the uniform velocity state (i.e. driving force is equal with resistance), if it is, performing step S2, otherwise, return to step S1 is counted again
Calculate TR speed and compare ig.
Specifically, gyroscope can be installed in vehicle interior, the acceleration magnitude a of vehicle is obtained by the gyroscope, if institute
State acceleration magnitude a and be in interval [- 0.05m/s2, 0.05m/s2] in, it is determined that Current vehicle is at the uniform velocity state.
S2, according to TR speed than determining automobile gear level.
TR speed is calculated than ig in step S1, and confirms that Current vehicle is in after computing state, obtain
TR speed than with the table of comparisons of automobile gear level, according to the table of comparisons and the TR speed for calculating than ig, really
Determine automobile gear level.
Wherein, TR speed is than the table of comparisons with automobile gear level, in embodiments of the present invention, the speed change of a certain vehicle
Gear box and speed are more as shown in the table than the table of comparisons, and the different gearbox tables of comparisons can be variant.
| Automobile gear level | TR speed is than (model 12JS**T) |
| 1 grade | 15.53 |
| 2 grades | 12.08 |
| 3 grades | 9.39 |
| 4 grades | 7.33 |
| 5 grades | 5.73 |
| 6 grades | 4.46 |
| 7 grades | 3.48 |
| 8 grades | 2.71 |
| 9 grades | 2.1 |
| 10 grades | 1.64 |
| 11 grades | 1.28 |
| 12 grades | 1 |
| Reverse gear | 14.86 |
| Neutral | ＜ 1 |
It should be noted that the numerical value of the TR speed ratio shown in upper table is the standard value corresponding to each gear,
In actual conditions, the TR speed that may be calculated is than ig and is not equal to standard value, therefore the present invention is matched by nearby principle
Corresponding standard value.For example, the TR speed being calculated is 5.00 than ig, it is in 5 grades of standard values 5.73 and 6 grades of marks
Between quasi- value 4.46, it differs 0.73 with 5.73, and 0.54 is differed with 4.46, therefore the standard value corresponding to 5.00 is 4.46, from
And corresponding automobile gear level is 6 grades.
S3, the can data according to the automobile gear level and vehicle determine vehicle-state.
Wherein, can data can be obtained from the can buses of vehicle, and various vehicle traveling numbers are included in can data
According to, such as speed, distance travelled, running time, current oil consumption, fuel consumption per hundred kilometers etc., the embodiment of the present invention is by automobile gear level
It is combined with can data, it can be determined that go out vehicle-state.
In vehicle operation, neutral gear is slided in the presence of harm, because now in the car running computer (ECU) of BBG
Will storage " DECEL ENLEAN " program, such as vehicle unclamps the reduction of throttle speed running at high speed in driver, car running computer this
When atomizer can be controlled to make the action of " DECEL ENLEAN ", do not have in cylinder body now fuel oil spray and fuel oil burn.Such feelings
Condition equivalent to " allowing vehicle with engine rotation ", with the reduction of speed, when engine speed falls below idling speed,
Oil spout recovers normal.If unclamping throttle is directly linked into neutral, after engine loses the tractive force passed over from trailing wheel, rotating speed
Can decline terribly, ECU will continue oil spout to keep idling.Meanwhile, engine is passed with chassis power train equivalent to moment of torsion
Defeated chain fracture, not because the braking moment of reaction produced by engine " counter to drag " passes to chassis under vehicle creep condition
Power train, causes the synthetical restraint ability of vehicle to decline.Due to being neutral gear, engine needs to remain idle to ensure normal operation
Speed operating, at this point for for heavy-duty diesel engine if the same reliability to engine of long-time idle running has very big shadow
Ring.
Specifically, when automobile gear level is neutral gear, and the speed is not zero and (threshold value can take less than a threshold value
When 50km/h), determine that vehicle-state is " low speed neutral gear sliding state ".Described in the embodiment of the present invention " low speed neutral gear slides shape
State " refer to speed it is relatively low in the case of vehicle hang neutral and be in sliding state, on the low speed links such as city, vehicle is in
" low speed neutral gear sliding state " be not substantially fuel-efficient, and there is driving risk, by identifying that " low speed neutral gear slides shape
State ", can remind driver the state reporting to vehicle management personnel, fleet management personnel in time.
Specifically, when automobile gear level be neutral gear, and speed be more than or equal to threshold value (threshold value can take 50km/h) when, it is determined that
Vehicle-state is " high speed neutral gear sliding state "." high speed neutral gear sliding state " described in the embodiment of the present invention refers to speed higher
In the case of vehicle hang neutral and be in sliding state, equally, the state there is also driving risk, so " the height by identifying
Fast neutral gear sliding state ", can be by the state reporting to vehicle management personnel so that fleet management personnel can in time to driving
The person of sailing is reminded.
Specifically, when vehicle has been started up, and the speed is when being zero, determines that vehicle-state is " idling mode ".This
" idling mode " described in inventive embodiments refer to vehicle motor work, but speed be 0, judge the meaning of the state
It is to reduce unnecessary dead time and idling oil consumption, reduces cost.
Specifically, when automobile gear level is not neutral, can data are tired out under different gears by a car-mounted terminal
Meter, to obtain running time and operating range of the vehicle under different gears, so that it is determined that going out vehicle under different range states
" distance travelled ", and " running time ".
S5, fleet management's platform is reported to by vehicle-state.
Specifically, above-mentioned vehicle-state is uploaded to fleet and managed by the embodiment of the present invention by vehicle-mounted Sim card communication modules
Platform, facilitates vehicle management personnel to know the state of each vehicle in time, so as to realize the intelligent driving behavior pipe of fleet
Reason.
Vehicle-state of the present invention includes but is not limited to above-mentioned " low speed neutral gear sliding state ", " high speed neutral gear is slided
Row state " and " idling mode ", can also include " hundred kilometers of gear shift frequencies ", " highest gear running time ", " in highest gear
Journey ", " the time accounting distribution of each gear ", the state such as " high-grade low speed ", " low gear with high ".
Fig. 3 schematically shows the graph of a relation of speed v and rotating speed n in the embodiment of the present invention, as shown in figure 3, transverse axis represents hair
Motivation rotating speed n, the longitudinal axis represents the speed v of vehicle, and the circle size in figure represents that vehicle is in a certain rotating speed and a certain speed
Under duration, circle is bigger, represents duration of the vehicle under the rotating speed and the speed more long.
Formula in from embodiment of the present invention step S1, in the case where automobile gear level is constant, speed v and rotating speed
N is linear relationship, and Fig. 3 shows the oblique line representated by 9~12 grades, and the circle size added up on every oblique line, is exactly at vehicle
In the time that the gear is travelled.
For line haul, vehicle is relatively more in the time shared by high tap position, and it is then more fuel-efficient, and driving habit also compares
Preferably, conversely, vehicle is relatively more in the time shared by low-grade location, it then gets over waste oil.
In addition, as shown in figure 3, first bubble in the lower left corner is idling accounting, speed is 0 under idling mode, therefore is accounted for
Higher than oil consumption higher, the bubbling polymerization in the upper left corner is high velocity " neutral position sliding state ".So, such as Fig. 3 can be seen that car
It is distributed in the time accounting of each gear, the state such as high-grade low speed, low gear with high, in addition：
Once putting flame-out for vehicle is a complete stroke, and system can record all of shift event in the process,
Such as 08：01：02 from 10 grades is changed to 12 grades, and hundred kilometers of gear shift frequencies can be just calculated when stroke terminates：Hundred kilometers
Gear shift frequency=(total shift number/total kilometrage) × 100 kilometers, this data can represent the driving habit of driver.
Once putting flame-out for vehicle is a complete stroke, and system meeting registration of vehicle is in highest gear in the process
The mileage of state, in general total kilometrage the inside highest gear mileage accounting is higher, and vehicle is more fuel-efficient, and this data can also represent
One driving habit of driver.
