Abstract
The invention discloses a method for measuring the fuel quantity of a fuel tank of a vehicle, and main parts comprise a fuel sensor, a vehicle-mounted terminal, an engine controller, and a wire. The method comprises the steps: firstly calibrating parameters of the fuel tank; secondly finding a fuel quantity calibrated value corresponding to a corresponding position from the vehicle-mounted terminal according to a resistance value outputted by the fuel sensor; thirdly measuring the fuel quantity between two positions; and finally correcting the calibration parameters of the fuel tank when the temperature of fuel changes. The change data of the fuel quantity is finer, and the authenticity of oil quantity data cannot be affected by temperature changes. The cost of the whole vehicle does not change, and no electrical fault is increased.
Description
Technical field
The invention belongs to oil tank of vehicle field, and in particular to a kind of vehicle fuel tank fuel quantity measuring method.
Background technology
Because commercial vehicle driver and car owner are not same people, when driver is to car owner's reimbursement plus cooking oil coupon, Jing is commonly present
The situation that actual oil mass consumption is not inconsistent with bill.To solve this problem, traditional technical scheme is by installing additional in fuel tank internal
High accuracy fuel-quantity transducer, using car-mounted terminal fuel tank liquid level change procedure is recorded.The defect of prior art：
1st, the additional works such as fuel tank perforate, cable need to be increased, workload is big and there is potential safety hazard；
2nd, precision fuel-quantity transducer is expensive, increases integral vehicle cost；
3rd, in the case of big volume fuel tank, oil mass changes too greatly between two grades of scales, it is impossible to realize accurately monitoring；
The content of the invention
The purpose of the present invention is a kind of vehicle fuel tank fuel quantity measuring method, Fuel Oil Remaining in accurate measurement oil tank of vehicle.
The technical scheme is that：A kind of vehicle fuel tank fuel quantity measuring method, wherein critical piece are sensed including oil mass
Device 1, car-mounted terminal 2, engine controller 3 and wire 4.
Specifically include following steps：
S1, fuel tank parameter calibration：When vehicle production is offline, demarcates oil tank of vehicle volume, oil mass in car-mounted terminal 2 and pass
The each gear resistance value table corresponding with oil mass and density corresponding at a certain temperature of sensor 1 and fuel oil temperature are corresponding with density
Table；The corresponding fuel density under fixed temperature of fuel-quantity transducer 1 is fixed；
S2, measurement：According to corresponding to the resistance value of the output of fuel-quantity transducer 1 finds corresponding gear in car-mounted terminal 2
The oil mass calibration value demarcated；
Oil measurement between S3, two grades：The timing of car-mounted terminal 2 asks currently to add up fuel consumption to engine controller 3
Amount, by it is current add up fuel consumption A deduct fuel-quantity transducer 1 from change to current gear for upper one grade when accumulative fuel consumption
Amount B obtains value C, and current gear point oil mass calibration value deducts the volume that value C is current real surplus oil mass；
S4, when fuel oil temperature changes, fuel tank calibrating parameters are modified：Fuel oil temperature change can also affect oil
The volume of amount, it is therefore desirable to the remaining oil value that above-mentioned steps four are obtained is modified according to fuel oil temperature, it is contemplated that save
Cost, does not install fuel temperature sensor additional in heavy truck, therefore, the ring that the timing monitoring engine controller 3 of car-mounted terminal 2 is sent
Border temperature parameter draws fuel density under Current Temperatures, according to close as fuel oil temperature according to fuel oil temperature table corresponding with density
Degree and volume relationship, correct in real time each gear resistance value and oil mass and the corresponding table of density of the fuel-quantity transducer 1 that early stage is demarcated.
S5, repeat the above steps S2～S4.
Beneficial effect：The present invention realizes the accurate prison of fuel tank fuel quantity change in the case where car load parts do not increase
Control.Oil mass conversion data are finer, will not affect the authenticity of oil mass data because of temperature change, and integral vehicle cost is unchanged, electrically
Trouble point does not increase.
