The specific calculation methods of the plant consumption and the logistics fuel consumption are respectively explained below.

Fuel consumption V of factory₃₁The calculation method comprises the following steps:

the fuel consumption in the factory after the vehicle is off-line includes the sensed fuel consumption and the fuel consumption moved at the time of the sensing. For convenience of calculation, the process that each detection is completed and the detection position is transferred to the next detection position is called a load end break, and the fuel consumption of the factory is equivalently calculated through the load end break.

The load end break comprises a static load end break and an idle load end break, the static load end break represents a process of passing through static detection and moving to a next detection position, and the dynamic load end break represents a process of passing through dynamic detection and moving to a next detection position. Wherein, static detection refers to detection without starting the engine, such as: (film-sticking protection, namely, not starting an engine, statically sticking a protective film of an engine shield and the like; commercial inspection, namely, statically confirming whether the appearance of the vehicle has obvious bruise and confirming that the clearance surface between two covers of four doors of the vehicle and a counterpart piece is poor); dynamic testing refers to the detection of the need to start the engine, for example: (in rain test, starting an engine, confirming whether water enters the vehicle or not in a rain line when the vehicle idles; AVES, and performing functionality and appearance size on the vehicle according to detection standards.)

The formula for calculating the fuel consumption of the static load end-to-end is as follows:

V_{31 quiet}＝c×s₁/100

In the formula, V_{31 quiet}Fuel consumption (in L) for each static load end-break, c is fuel consumption per hundred kilometers (in L/100km) in the cold start state of the vehicle, s₁An average moving distance (in km) for a vehicle to have one detected location move to the next;

the dynamic load end-break fuel consumption calculation formula is as follows:

V_{31 move}＝a×t/60+c×s₁/100

In the formula, V_{31 move}The fuel consumption (unit is L) for each dynamic load end-to-end, a is the fuel consumption (unit is L/h) of the vehicle in an idle state, and t is the average time (unit is min) taken by the vehicle for dynamic detection;

plant consumption V₃₁The calculation formula of (2) is as follows:

V₃₁＝d₁×V_{31 quiet}+d₂×V_{31 move}

＝d₁×c×s₁/100+d₂×(a×t/60+c×s₁/100)

In the formula (d)₁For the total number of static tests, d₂Is the total number of dynamic tests performed.

Optionally, considering that the oil consumption of the test requiring the vehicle in the idle state is obviously different from the oil consumption of the test requiring the vehicle in the back-towed state on the hub test stand during dynamic detection, when calculating the plant consumption, the detection of the hub test stand and the idle detection are separately calculated, specifically, the plant consumption V is calculated₃₁The calculation formula of (2) is as follows:

V₃₁＝d₁×V_{31 quiet}+d₂₁×V_{31 move}+e

＝d₁×c×s₁/100+d₂₁×(a×t/60+c×s₁/100)+e

In the formula (d)₂₁For the total number of idle speed detections in the dynamic detection, e is the average fuel consumption (in L) detected by the turret table.

Optionally, considering that some manufacturers may randomly extract some vehicles for spot check detection in addition to the conventional detection items when performing factory inspection, in order to ensure that the oil injection amount of the vehicle is sufficient to complete the spot check detection, the factory consumption amount needs to be floated by 50%, that is, the factory consumption amount V is increased by 50%₃₁The calculation formula of (2) is as follows:

V₃₁＝(d₁×V_{31 quiet}+d₂×V_{31 move})×150％

＝(d₁×c×s₁/100+d₂×(a×t/60+c×s₁/100))×150％

Optionally, the fuel consumption V of the computing factory is calculated by considering that the hub platform detection is a conventional detection item and the hub platform detection is not included in the random detection item₃₁When the oil consumption of the idling part and the transfer part is floated, the oil consumption of the idling part and the transfer part is only needed to be floated, and particularly, the factory consumption V is realized₃₁The calculation formula of (2) is as follows:

V₃₁＝(d₁×V_{31 quiet}+d₂₁×V_{31 move})×150％+e

＝(d₁×c×s₁/100+d₂₁×(a×t/60+c×s₁/100))×150％+e

Logistics fuel consumption V₃₂The calculating method of (2):

after the vehicle is detected, the vehicle needs to be moved from the detection position to the transport vehicle and transported by the transport vehicle to a dealer for sale, and in order to ensure that the vehicle has enough fuel quantity, the fuel consumption of logistics is calculated by the farthest distance between the detection position and the transport vehicle.

The calculation formula of the logistics fuel consumption is as follows:

V₃₂＝c×s₂/100

in the formula, s₂The farthest distance from the detected position to the transport vehicle. Considering the speed limit of a factory, the speed of a vehicle is generally within 15km/h, so that the fuel consumption of logistics of the vehicle is calculated by using the fuel consumption of hundreds of kilometers in the cold starting state of the vehicle.

Optionally, considering driving habits of different drivers and conditions of starting the air conditioner, the logistics fuel consumption is floated by 50%, and then the calculation formula of the logistics fuel consumption is as follows:

V₃₂＝c×s₂/100×150％

optionally, as shown in fig. 2, if an unqualified condition exists in the detection process, rework is required, and in consideration of that rework is a random event, temporary fuel oil filling may be performed on the vehicle that needs to be reworked, the amount of fuel oil filling is determined according to the rework fuel consumption, and the specific calculation method of the rework fuel consumption is as follows:

V_{return to}＝s₃×c/100+d₁₁×V_{31 quiet}+d₂₂×V_{31 move}

＝s₃×c/100+d₁₁×c×s₁/100+d₂₂×(a×t/60+c×s₁/100)

In the formula, s₃To detect the distance between the defective inspection position and the rework position, d₁₁For the number of static detections that need to be performed again, d₂₂For the number of times that the re-dynamic detection is required.

The invention also provides a system for setting the offline fuel filling amount of a factory, which comprises the following components:

the model construction module is used for constructing a load end-break fuel consumption model, wherein the fuel filling amount in the model comprises the fuel amount of accessory parts of a fuel system, the fuel amount which cannot be sucked by a static fuel pump and the fuel consumption V in factory and logistics transportation₃；

The system is mainly used for realizing the method for setting the offline fuel filling amount of the factory, and the specific calculation process of each module is described in detail in the method and is not described herein any more.

In conclusion, the invention not only ensures that the vehicle can be smoothly detected and transported, but also can furthest reduce the fuel cost by estimating the fuel consumption before the vehicle leaves the factory and in the logistics process and injecting just enough fuel. The fuel consumption of the vehicle in the detection process is equivalently calculated by constructing a load end-break fuel consumption model, and the fuel consumption of the vehicle in the detection process in a factory is accurately and conveniently calculated.

Further, the fuel consumption in the detection process is further improved by separately calculating the fuel consumption of the idle speed detection and the fuel consumption of the hub platform reverse dragging detection.

Furthermore, the oil consumption in the factory is floated by 50 percent to ensure that the oil injection quantity can meet the requirement of random sampling inspection.

Furthermore, considering the speed limit in a factory, the logistics oil consumption is calculated by using the hundred kilometers of oil consumption in the cold start state of the vehicle, so that the accuracy of the calculation of the logistics oil consumption is improved.

Further, a repair oil injection quantity model is constructed, and vehicles needing repair are temporarily filled, so that the repair requirement is met.
