Description
Technical field
The invention belongs to oil tank of vehicle fields, and in particular to a kind of vehicle fuel tank fuel quantity measurement method.
Background technique
Since commercial vehicle driver and car owner are not same people, it is frequently present of when driver submits an expense account oiling ticket to car owner
Not the case where actual oil mass consumption is not inconsistent with bill.To solve this problem, traditional technical solution is by installing additional in fuel tank internal
High-precision fuel-quantity transducer records fuel tank liquid level change procedure using car-mounted terminal.The defect of the prior art:
1, the additional works such as fuel tank aperture, cable need to be increased, heavy workload and there are security risks；
2, precision fuel-quantity transducer is expensive, increases integral vehicle cost；
3, in the case of big volume fuel tank, oil mass variation too greatly, can not achieve accurate monitoring between two grades of scales；
Summary of the invention
The purpose of the present invention is a kind of vehicle fuel tank fuel quantity measurement method, Fuel Oil Remaining in precise measurement oil tank of vehicle.
The technical solution of the present invention is as follows: a kind of vehicle fuel tank fuel quantity measurement method, wherein main component includes oil mass sensing
Device 1, car-mounted terminal 2, engine controller 3 and conducting wire 4.
Specifically includes the following steps:
S1, fuel tank parameter calibration: when vehicle production is offline, oil tank of vehicle volume is demarcated in car-mounted terminal 2, oil mass passes
Sensor 1 corresponding at a certain temperature each gear resistance value table corresponding with oil mass and density and fuel oil temperature and density are corresponding
Table；The fuel density corresponding under fixed temperature of fuel-quantity transducer 1 is fixed；
S2, measurement: the resistance value exported according to fuel-quantity transducer 1 is found corresponding to corresponding gear in car-mounted terminal 2
The oil mass calibration value demarcated；
Oil measurement between S3, two grades: 2 timing of car-mounted terminal requests currently to add up fuel consumption to engine controller 3
The current fuel consumption A that adds up is subtracted fuel-quantity transducer 1 from accumulative fuel consumption when changing to current gear for upper one grade by amount
Amount B obtains value C, and current gear point oil mass calibration value subtracts 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 variation also will affect oil
The volume of amount, it is therefore desirable to the remaining oil magnitude that above-mentioned steps four obtain is modified according to fuel oil temperature, it is contemplated that save
Cost does not install fuel temperature sensor additional in heavy truck, therefore, car-mounted terminal 2 is periodically monitored to the ring that engine controller 3 issues
Border temperature parameter obtains fuel density under Current Temperatures as fuel oil temperature, according to fuel oil temperature table corresponding with density, according to close
Degree and volume relationship correct each gear resistance value and the corresponding table of oil mass and density of the fuel-quantity transducer 1 of calibration early period in real time.
S5, repeat the above steps S2~S4.
The utility model has the advantages that the present invention in the not increased situation of vehicle components, realizes the accurate prison of fuel tank fuel quantity variation
Control.Oil mass transformation data are finer, the authenticity of oil mass data will not be influenced because of temperature change, and integral vehicle cost is unchanged, electrically
Fault point does not increase.
