Detailed description of the invention
The present invention will be further described below with reference to the drawings.
Fig. 1 is flow chart of the present invention for the doubles gas signal control method of integral new-energy passenger.
Specific embodiment
Below in conjunction with the embodiment of the present invention, technical scheme in the embodiment of the invention is clearly and completely described,
Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based in the present invention
Embodiment, all other embodiment obtained by those of ordinary skill in the art without making creative efforts, all
Belong to the scope of protection of the invention.
Refering to Figure 1, present embodiments providing a kind of doubles gas signal control method for integral new-energy passenger, wrap
Include following steps：
After entire car controller powers on, the first, second fault bit is reset, and in fixed cycle time, is held repeatedly
Row following steps.
The first, second road air pressure signal, that is, analog voltage is acquired by baroceptor, and carries out three to signal collected
Group data are averaged processing, as air pressure processing costs Air_pressure1, Air_pressure2, that is, data filtering processing, obtain
After processing costs Air_pressure1, Air_pressure2, into judgment step (2).
Judge Air_pressure1, Air_pressure2 whether in threshold range.Wherein, the minimum value of threshold range
For the first, second air pressure signal theoretical minimum value plus the value after tolerance；Maximum value is the first, second air pressure signal
Theoretical maximum adds the value after tolerance.Because the voltage value of different baroceptors feedback is different, this example is with 0.498
Minimum value, 4.505 be maximum value.
First, second fault bit indicates that the first, second road atmospheric pressure value whether there is failure.When the first, second fault bit quilt
When set, indicating corresponding gas circuit, there are failures, indicate that failure is not present when being zero.Failure reset count value indicates first, the
When two fault bits are set, if Air_pressure1, Air_pressure2 restore normally, continuing normal one section again
In time, failure reset count value persistently adds one, resets the first, second fault flag when it reaches limit value.
In judgement (2), if Air_pressure1 < 0.498 or Air_pressure1 > 4.505, and Air_
Pressur2 >=0.498 and Air_pressur2≤4.505, then using Air_pressure2 as processing costs, by Fisrt fault position
Set；If Air_pressure2 < 0.498 or Air_pressure2 > 4.505, and Air_pressur1 >=0.498 and Air_
Pressur1≤4.505, then using Air_pressure1 as processing costs, by the second fault bit set；If Air_pressure1,
Air_pressure2 is respectively less than 0.498 or is all larger than 4.505, then disorderly closedown, by the first, second fault bit set.
In judgement (2), if Air_pressur1, Air_pressur2 are all larger than equal to 0.498 and are less than or equal to
4.505, it is transferred to (3).
In judgment step (3), judge that the ratio of Air_pressure1 and Air_pressure2 whether in threshold value, leads to
This judgement is crossed, further the accurate accuracy of two-way atmospheric pressure value.In this example, the threshold range of ratio takes 0.9-1.1.
If ratio in this section, is inflated starting and is started with lower value in Air_pressure1 and Air_pressure2, stop with
Lower value stops in Air_pressure1 and Air_pressure2, the average value of Air_pressure1 and Air_pressure2
As vehicle atmospheric pressure value；If ratio not in the section 0.9-1.1, is transferred to step (5).
In judgment step (5), whether first, second road atmospheric pressure value Air_pressure1, Air_pressure2 of detection
Same sample value is continuously taken, because the most common performance is continuously to take same value in baroceptor exception or in the case where go offline.
By the method, facilitate where detecting fault-signal, thus the atmospheric pressure value all the way of debug.If continuously taking same sample value
Not repeat to take the parameter of same sample value as atmospheric pressure value, otherwise, because two paths of signals meets 1 He of threshold k in judgement before
The condition of K2, so, under the premise of guaranteeing that vehicle is safe and reliable, with being averaged for Air_pressure1, Air_pressure2
Value is used as atmospheric pressure value.
In conclusion the present invention, which passes through, judges two-way air pressure signal whether in threshold range, further to two paths of signals
Whether ratio is judged in threshold range, increases the accuracy of signal.It in addition is not straight during handling signal
It connects judgement and inflates signal fault, but two-way fault bit is detected, selection does not have faulty all the way as actual pressure value.
Further, in signal not in the case where threshold range, present invention also adds whether continuously take identical value to two paths of signals
Judged.In baroceptor exception or in the case where go offline, help to detect fault-signal by this judgment method
Place, and guarantee that vehicle inflates being normally carried out of work.
