Abstract
The invention discloses a processing method for a fuel gauge of an automobile combination meter. The processing method is applied to an automobile with fuel consumption information. Based on the conventional hardware integrated with a meter and a fuel sensor, real-time fuel consumption information is added, and then remaining fuel in a fuel tank can be accurately fed back in real time through a control strategy of the fuel gauge of the combination meter. According to the invention, the situation that fuel gauge indicates wrong when a vehicle parks on bumpy road surface, up/down hills or a slope can be avoided, meanwhile the software complexity of the combination meter is reduced, and the whole reliability degree is improved.
Description
Technical field
The invention belongs to vehicle electric field, relate in particular to a kind of disposal route of automobile combination meter fuel level gauge.
Background technology
At present, automobile oil mass table is by microprocessor, the resistance signal in fuel sensor to be carried out being converted into digital signal after analog sampling, then the segment encode that digital signal is converted into the step number of motor or LCD screen is realized to the indication of vehicle Fuel Oil Remaining.But in Vehicle Driving Cycle process, due to road bump, turning round and acceleration and deceleration or the factor such as parking on ramp for a long time of vehicle, can cause that the pasta in fuel tank rocks, cause having a larger deviation for a long time between output oil mass on fuel sensor and actual fuel tank fuel quantity, algorithm and strategy that this deviation utilization is current all cannot be avoided.Will cause like this fuel level gauge indication on combination instrument inaccurate, to user, bring wrong judgement.
Summary of the invention
Technical matters to be solved by this invention be realize a kind of reliably, automobile oil gauge amount disposal system and method accurately.
To achieve these goals, the technical solution used in the present invention is: automobile combination meter fuel level gauge disposal route, is characterized in that:
The indication range of automobile combination meter fuel level gauge is associated in proportion with the volume of fuel tank;
Refueled total oil mass of post consumption the total oil mass-last time after refueled the oil mass that automobile combination meter fuel level gauge shows=last time;
After each oiling, will allow total fuel consumption start from scratch again accumulates and calculates;
With this demonstration oil mass that circulates.
According to the variation of the oil tank fuel amount after stop closing igniting and while making war fire, whether be greater than minimum volume read-out, or stop be not related to igniting after and the variation of the oil tank fuel amount of car while starting whether be greater than minimum volume read-out and judge whether oiling.
After stop closing igniting and stop after being not related to igniting need to gather oil tank fuel amount after time rating.
Be 8 seconds described time rating.
It is inaccurate that the present invention can effectively avoid fuel tank fuel quantity deviation of signal that fuel sensor that road conditions cause obtains to cause oil meter to show, guaranteed accuracy and the reliability of the Fuel Oil Remaining of fuel level gauge indication under complex road condition.This scheme can be used the existing hardware facility of combination instrument, need not increase the cost of development of hardware, has reduced development cost and the complex software degree of combination instrument.
Accompanying drawing explanation
Below the content of every width accompanying drawing expression in instructions of the present invention and the mark in figure are briefly described:
Fig. 1 is automobile combination meter fuel level gauge process flow figure.
Embodiment
The present invention is on the basis of original sensor and combination instrument, increase the signal of an oil consumption, utilize the difference of the initial oil mass of fuel tank and oil supply to obtain Fuel Oil Remaining, so just can avoid the problems such as the shake of fuel level gauge pointer in driving process or LCD segment encode and distortion, and can effectively solve vehicle on the road surface of jolting, fuel level gauge misdirection when climb and fall or stopping on hill reduces the software complexity of combination instrument simultaneously, has improved whole fiduciary level.Concrete disposal route is as follows:
The signal that step 1 gathers vehicle fuel sensor is used for detecting the oil mass in fuel tank, gathers switch ignition and vehicle speed signal and is used for judging whether refueling, and gathers oil consumption signal for detection of total oil consumption;
Step 2 is according to the state of switch ignition and speed of a motor vehicle state, current Fuel Oil Remaining and fuel tank fuel quantity judge whether vehicle refuels: the difference of the fuel tank fuel quantity after the fuel tank fuel quantity when making war fire and pass igniting 8s is greater than minimum volume read-out, or the variation of the oil tank fuel amount after parking is not related to igniting 8s and when car starts is greater than minimum volume read-out, just can judge that fuel tank refuels; Otherwise judgement is not refueled, and by 8 second off time, can avoid fuel tank to rock the measuring error of bringing;
Step 3, according to fueling state and fuel tank fuel quantity, determine the initial oil mass of fuel tank: if be judged to be oiling, current oil mass, previous step battle fire or vehicle take-offs fuel tank fuel quantity be constantly initial oil mass, otherwise the initial oil mass of oil mass remains unchanged;
Step 4, according to vehicle whether initial fuel tank fuel quantity and oil supply are determined in oiling: from judging that the moment that vehicle refueled, total oil consumption is accumulated again according to oil consumption signal, otherwise remains unchanged;
The indication of step 5 fuel level gauge: deduct total oil consumption in step 4 according to the initial oil mass of determining in step 3, just can obtain the Fuel Oil Remaining of fuel tank, then, under fired state, allow pointer or LCD segment encode be indicated to corresponding position.
The technical characterstic that the present invention adopts is: in vehicle traveling process, the Fuel Oil Remaining of combination instrument fuel level gauge indication is to be obtained by the initial oil mass of fuel tank and the difference of oil supply, irrelevant with the fuel tank fuel quantity signal obtaining from fuel sensor processing, thereby it is inaccurate to avoid fuel tank fuel quantity deviation of signal that fuel sensor that road conditions cause obtains to cause oil meter to show, has guaranteed accuracy and the reliability of the Fuel Oil Remaining of fuel level gauge indication under complex road condition.This scheme can be used the existing hardware facility of combination instrument, need not increase the cost of development of hardware, has reduced development cost and the complex software degree of combination instrument.
