Specific embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein identical from start to finish
Or similar label represents same or similar element or the element with same or like function.Retouch below with reference to accompanying drawing
The embodiment stated is exemplary, it is intended to for explaining the present invention, and be not considered as limiting the invention.
Below with reference to the accompanying drawings detection method, device and the vehicle of the remaining fuel of fuel tank of the embodiment of the present invention are described.
Fig. 1 is the flow chart of the detection method of remaining fuel of fuel tank according to an embodiment of the invention.As shown in figure 1, this
The detection method of the remaining fuel of fuel tank of inventive embodiments, comprises the following steps：
S1, obtains the grade signal on road surface residing for vehicle.
In one embodiment of the invention, the grade signal on road surface residing for vehicle is detected by angular transducer.
In another embodiment of the present invention, by the grade signal on road surface residing for ESP sensor detected vehicles.
Wherein, there are two kinds of calculations by the grade signal on road surface residing for ESP sensor detected vehicles, in detail below
Explanation.
The first calculation：Obtain level ground offset signal value m of ESP sensors；And it is inclined according to level ground
Shifting amount signal value m calculates grade signal.
For example, with m=319 as level ground, it is 1 degree per 6 units, then, grade signal=(m-319)/6.
Second calculation：Obtain the accekeration of ESP sensors, and engine torque accekeration；And according to ESP
The accekeration of sensor and engine torque accekeration calculate grade signal.
Specifically, the calculation adopts graphics calculations method, it is assumed that required angle is α, then
Sin α=| Aesp-Av |/g,
Wherein, the accekeration that Aesp is sent for ESP sensors, Av are transmitted through the accekeration for coming for engine torque,
G is acceleration of gravity.
With the value that α is obtained by arcsin function after calculating sin α.Calculated before grade signal by this calculation
Carry is to need the accekeration and engine torque accekeration of ESP sensors for known.
S2, if judging that vehicle, in level ground, further obtains present amount and instantaneous oil consumption according to grade signal.
For example, when the gradient on road surface residing for the vehicle for getting is in [- 2 °, 2 °], judge that vehicle is in level ground.
Further, if it is determined that vehicle is in level ground, then present amount a and instantaneous oil consumption are obtained.Wherein, car
EFI in sends the signal of instantaneous oil consumption to HVN, forwards out from HVN by gateway, and instrument is collected from gateway
This signal, that is, got instantaneous oil consumption.
S3, calculates instrument fuel oil show value according to present amount and instantaneous oil consumption.
For example, will on vehicle during ON shelves electricity as original state, on the vehicle when ON shelves electricity, instrument is by collection
The signal of fuel level sensor is obtaining present amount, and is shown in instrument.
Specifically, after vehicle is started running, as vehicle is in different road conditions, such as urgency accelerates, bend row of bringing to a halt
When sailing, the pasta in fuel tank is unstable, then, directly will be forbidden by the remaining oil value collected by fuel level sensor,
It is of the invention then in the following manner calculate instrument fuel oil show value.
In one embodiment of the invention, S3 is specifically included：
If present amount is less than the first oil mass threshold value, instrument fuel oil show value=present amount-instantaneous oil consumption；
If present amount is more than the first oil mass threshold value and is less than the second oil mass threshold value, instrument fuel oil show value=current fuel
Amount-N × instantaneous oil consumption, wherein, N is positive integer；
And if present amount is more than the second oil mass threshold value, then instrument fuel oil show value=present amount-instantaneous oil consumption.
Preferably, N=(second oil mass threshold value the-the first oil mass threshold value)/2.
Specifically, for example, when vehicle is in traveling, if current amount of fuel is a.When remaining oil in fuel tank
When measuring fewer, may be detected less than in order that instrument fuel oil show value is closer to real surplus oil by fuel level sensor
Value, using following policy calculation instrument fuel oil show value, that is, works as a<7L (wherein, 7L is the citing to the first oil mass threshold value)
When, instrument fuel oil show value=a-instantaneous oil consumption；
Work as 7L<a<During 13L (wherein, 13L is the citing to the second oil mass threshold value), due to now remaining oil mass not
Be enough to travel too remote distance, in order to allow instrument to send warning as early as possible to remind user, instrument fuel oil show value=a -3* are instantaneous
Oil consumption；
Work as a>During 13L, instrument fuel oil show value=a-instantaneous oil consumption.
With the traveling of vehicle, instrument fuel oil show value may produce error, then, it is necessary to instrument fuel oil show value
Calibration is updated, the strategy then to updating calibration is illustrated below.
In one embodiment of the invention, the detection method of remaining fuel of fuel tank, also includes：If present amount is more than
3rd oil mass threshold value, then what the first oil mass changing value and electronic injection fuel consumption that fuel level sensor is generated in acquisition Preset Time was generated
Second oil mass changing value；If the first oil mass changing value is less than the second oil mass changing value, according to the first oil mass changing value to working as
Front amount of fuel is updated.
For example, work as a>During 15L (wherein, 15L is the citing to the 3rd oil mass threshold value), instrument need to be judged, and work as judgement
It is updated when meeting condition again.
Specifically, the change (value that i.e. fuel level sensor is transmitted) of instrument continuous acquisition 10S oil mass is oily to generate first
Amount changing value, and contrasted with the second oil mass changing value of electronic injection fuel consumption generation in Preset Time before this, if the first oil mass
Changing value is less than the second oil mass changing value, then present amount is updated according to the first oil mass changing value.Wherein, carry out
The cycle for updating calibration is the Preset Time.
In theory, all accomplish fuel consumption as fuel oil can not possibly reach 100% utilization, each oil dripping, so first
Oil mass changing value is certainly less than the second oil mass changing value, then be defined by the change of oil mass by fuel level sensor, can be with
Avoid what the fuel oil that each place of oil leak, engine does not cmpletely utilize was brought to instrument fuel oil show value in this process
Error.For example, if original remaining fuel of fuel tank is 40L, after 20 minutes, the residue obtained by fuel level sensor
Oil mass is 37L, i.e. the first oil mass changing value is 3L, and the second oil mass changing value that electronic injection fuel consumption is generated in 20 minutes is 4L,
Then present amount is updated according to the first oil mass changing value, that is, present amount is updated to into 37L, and synchronously
Renewal memory value is 37L.
Further, since some cause specifics, are likely to result in the first collected oil mass changing value and change more than the second oil mass
The situation of value, in this case, the instrument then change of continuous acquisition 10S oil mass always, until judging that the first oil mass changes
When value is less than the second oil mass changing value, present amount is updated further according to the first oil mass changing value.
In one embodiment of the invention, also include：If present amount is less than the 3rd oil mass threshold value, not to current
Amount of fuel is updated calibration.
Specifically, if present amount is less, such as a<During 15L, instrument fuel oil show value is then always according to instantaneous oil consumption
Successively decrease, do not do any renewal calibration.
In addition, the detection method of the remaining fuel of fuel tank of the embodiment of the present invention, also including crash handling strategy：
1. when by the grade signal on road surface residing for ESP sensor detected vehicles when, if ESP sensors there occurs failure or
Do not demarcate, then it is level ground to give tacit consent to road surface residing for vehicle；
2. when fuel level sensor signal is opened a way, then according to empty oil processing.
