Referring to fig. 2, fig. 2 is a schematic flow chart of a method for testing fuel consumption of a vehicle according to a first embodiment of the present invention, and the method for testing fuel consumption of a vehicle according to the first embodiment of the present invention is provided.
Step S10: and when a vehicle oil consumption test instruction is received, acquiring a current test identification corresponding to the vehicle to be tested.
It should be understood that the execution subject of the embodiment is the vehicle fuel consumption testing device, where the vehicle fuel consumption testing device may be an electronic device such as a computer and a server, and may also be other devices that can achieve the same or similar functions.
It should be noted that the vehicle oil consumption test instruction may be a control instruction input by a user through a user interaction interface of the vehicle oil consumption test device; or the control instruction may be a control instruction input by the user through a terminal device of the vehicle oil consumption testing device in advance, which is not limited in this embodiment; the test identifier may be identification information preset by a user and used for identifying the test item, for example, the test identifier 1 may be used for identifying the idle oil consumption test item, the test identifier 2 may be used for identifying the vehicle speed oil consumption test item, and the test identifier 3 may be used for identifying the working condition oil consumption test item, which is not limited in this embodiment.

Step S20: and determining a current test item according to the current test identification, and controlling the vehicle to be tested to execute the current test item to obtain a test result.
It should be understood that the current test identifier may be at least one of a preset idle fuel consumption test identifier, a preset vehicle speed fuel consumption test identifier, and a preset operating condition fuel consumption test identifier, which is not limited in this embodiment.
In a specific implementation, for example, the preset idle oil consumption test item may be that the vehicle is turned on at idle to discharge until the engine is started and charged, the air conditioner is turned off to start the test, and the test is completed after the engine is stopped after time t.
The vehicle speed test items can be the vehicle speed test items which are connected with a fuel consumption meter when the vehicle speed is low, such as 60km/h driving, the running at a constant speed of 60km/h is tested by using a certain battery electric quantity (SOC), the running is in a pure electric mode when the SOC is higher, the engine is not started, when the SOC is lowered to a certain value (e.g. 25%) the engine starts to drive the tires directly, and the battery is charged, the engine is stopped when the SOC is gradually increased to a certain value (such as 45 percent), the pure electric mode is continuously entered, the above steps are repeated in a circulating way, after about 10 minutes of testing, two points with the same SOC which are far away from each other are taken, taking 25% SOC as an example, take the first point of 25% S0C and the last point of 25% SOC within 10 minutes, the fuel consumption in the period is the constant-speed fuel consumption without the battery charging and discharging factors, and the constant-speed fuel consumption is objectively and truly represented.
When the vehicle speed is high, because the battery is charged and discharged quickly, frequent engine starting and stopping switching is not beneficial to saving oil, therefore, the current test items are that the engine is directly driven, the SOC is controlled at the target SOC, the engine is directly driven and the battery is charged when the SOC is increased to a certain value (such as 75%) and is only driven independently, therefore, the test data is recorded from the moment, the SOC value is still unchanged after about 10 minutes, and the fuel consumption measured in the 10 minutes can represent the actual fuel consumption level of the constant-speed 120km/h driving.
The working condition test items can take WLTC as an example, the vehicle is discharged until the engine is started, the SOC of the vehicle battery is ensured to be about 50%, the SOC of the vehicle battery is fully charged until the vehicle battery cannot be charged, the oil consumption of WLTC heat engine circulation working conditions in three states is respectively tested, and the initial SOC value and the final SOC value are recorded. And comparing the oil consumption difference and the SOC difference of the three tests to obtain a conversion relation between the SOC and the oil consumption, converting the change of the SOC into the change of the oil consumption in the results of the three tests, finally obtaining the final oil consumption test result of the three tests after eliminating the influence of the SOC, and taking the average value as the WLTC heat engine cycle working condition oil consumption of the vehicle.

It should be understood that the extracting of the information of the test result to obtain the fuel consumption parameter and the battery parameter may be extracting the identifier of the test result to obtain the information identifier, and screening the test result according to the information identifier to obtain the fuel consumption parameter and the battery parameter.
It can be understood that the generating of the fuel consumption test result according to the fuel consumption parameter and the battery parameter may be generating a fuel consumption test result table according to the fuel consumption parameter and the battery parameter through a preset table template, where the preset fuel consumption test result table may be a table preset by a user.
Also, for ease of understanding, reference is made to table 1 for illustration:

Accordingly, the step S20 includes:

Further, the step S20' includes:
when the current test identification is a preset idle oil consumption test identification, taking a preset idle oil consumption test item as a current test item;
controlling the vehicle to be tested to execute the current test item;
after the current test item is executed, acquiring fuel consumption data and battery electric quantity data of the vehicle to be tested;
and generating an idle oil consumption test result according to the fuel consumption data and the battery electric quantity data.
It should be noted that the preset idle fuel consumption test identifier may be identifier information preset by a user and used for representing an idle fuel consumption test item. For example, the user may preset the test identifier 1 as a preset idle fuel consumption test identifier, which is not limited in this embodiment.
It should be understood that the preset idle fuel consumption test item may be a fuel consumption test item in an idle state preset by a user.
In a specific implementation, for example, the preset idle oil consumption test item may be that the vehicle is turned on at idle to discharge until the engine is started and charged, the air conditioner is turned off to start the test, and the test is completed after the engine is stopped after time t.
It should be noted that the fuel consumption data may be the fuel consumption of the vehicle to be tested to execute the current test item; the battery power data may be a battery charge amount of the vehicle to be tested executing the current test item, which is not limited in this embodiment.
It CAN be understood that the fuel consumption data of the vehicle to be tested CAN be obtained through the CAN bus, and the fuel consumption data uploaded by the fuel consumption meter CAN be obtained through the CAN bus, and the battery electric quantity data of the vehicle to be tested CAN be obtained through the CAN bus, and the test voltage and the test current uploaded by the current clamp CAN be obtained.
It should be understood that, the generation of the idle fuel consumption test result according to the fuel consumption data and the battery power data may be to calculate the idle fuel consumption value according to the fuel consumption data and the battery power data by a preset idle fuel consumption formula,
the preset idle oil consumption formula is as follows:
in the formula, s is an idle oil consumption value and is represented by L/kwh, o is fuel consumption data, is represented by L, and e is battery power data and is represented by kwh.
Further, the step S20' includes:
when the current test item identifier is a preset vehicle speed and fuel consumption test identifier, acquiring a vehicle speed to be tested;

acquiring fuel consumption data of the vehicle to be tested after the current test item is executed;
and after traversing the vehicle speed to be tested, generating a vehicle speed and fuel consumption test result according to the fuel consumption data.
It should be noted that the preset vehicle speed fuel consumption test identifier may be identifier information preset by a user and used for representing a vehicle speed fuel consumption test item. For example, the user may preset the test identifier 2 as a preset vehicle speed and fuel consumption test identifier, which is not limited in this embodiment. The vehicle speed to be tested can be a test vehicle speed preset by a user. For example, 60km/h, 90km/h, 120km/h, 140km/h, etc., which is not limited in this embodiment.
It should be understood that, the searching for the current test item corresponding to the current test vehicle speed may be to search for the current test item corresponding to the current test vehicle speed in a preset vehicle speed test item table, where the preset vehicle speed test item table includes a corresponding relationship between the current test vehicle speed and the current test item, and the corresponding relationship between the current test vehicle speed and the current test item may be preset by a user according to an actual requirement, which is not limited in this embodiment.
In a specific implementation, for example, when the vehicle speed is low, such as 60km/h driving, the fuel consumption meter is connected, the constant speed of 60km/h running is tested by starting with a certain battery electric quantity (SOC), the running is in a pure electric mode when the SOC is higher, an engine is not started, when the SOC is lowered to a certain value (e.g. 25%) the engine starts to drive the tires directly, and the battery is charged, the engine is stopped when the SOC is gradually increased to a certain value (such as 45 percent), the pure electric mode is continuously entered, the above steps are repeated in a circulating way, after about 10 minutes of testing, two points with the same SOC which are far away from each other are taken, taking 25% SOC as an example, take the first point of 25% S0C and the last point of 25% SOC within 10 minutes, the fuel consumption in the period is the constant-speed fuel consumption without the battery charging and discharging factors, and the constant-speed fuel consumption is objectively and truly represented.
When the vehicle speed is high, because the battery is charged and discharged quickly, frequent engine starting and stopping switching is not beneficial to saving oil, therefore, the current test items are that the engine is directly driven, the SOC is controlled at the target SOC, the engine is directly driven and the battery is charged when the SOC is increased to a certain value (such as 75%) and is only driven independently, therefore, the test data is recorded from the moment, the SOC value is still unchanged after about 10 minutes, and the fuel consumption measured in the 10 minutes can represent the actual fuel consumption level of the constant-speed 120km/h driving.
It can be understood that after the traversal of the vehicle speed to be tested is finished, the vehicle speed to be tested is completely tested. At the moment, the vehicle speed and fuel consumption test result can be directly generated according to the fuel consumption data.
Further, the step S20' includes:
when the current test item identifier is a preset working condition oil consumption test identifier, acquiring a working condition to be tested;
traversing the working condition to be tested, and taking the traversed working condition to be tested as the current testing working condition;
searching a current test item corresponding to the current test working condition, and controlling the vehicle to be tested to execute the current test item;
after the current test item is executed, acquiring fuel consumption data and battery electric quantity data of the vehicle to be tested;
and after traversing the to-be-tested working condition information, generating a working condition oil consumption test result according to the fuel oil consumption data and the battery electric quantity data.
It should be noted that the preset operating condition oil consumption test identifier may be identifier information preset by a user and used for representing an operating condition oil consumption test item. For example, the user may preset the test identifier 3 as a preset operating condition oil consumption test identifier, which is not limited in this embodiment. The test condition to be tested can be a test condition preset by a user. For example, the power feed WLTC, the medium power WLTC, the full power SOC, and the like, which are not limited by the embodiment.
It can be understood that, the searching for the current test item corresponding to the current test condition may be searching for the current test item corresponding to the current test condition in a preset condition test item table, where the preset condition test item table includes a corresponding relationship between the current test condition and the current test item, and the corresponding relationship between the current test condition and the current test item may be preset by a user according to an actual requirement, which is not limited in this embodiment.
In the concrete implementation, taking WLTC as an example, discharging the vehicle until the engine is started, ensuring the SOC of a vehicle battery to be about 50%, fully charging the SOC of the vehicle battery until the SOC of the vehicle battery cannot be charged, respectively testing the oil consumption of WLTC heat engine cycle conditions in three states, and recording the initial SOC value and the final SOC value. And comparing the oil consumption difference and the SOC difference of the three tests to obtain a conversion relation between the SOC and the oil consumption, converting the change of the SOC into the change of the oil consumption in the results of the three tests, finally obtaining the final oil consumption test result of the three tests after eliminating the influence of the SOC, and taking the average value as the WLTC heat engine cycle working condition oil consumption of the vehicle.
In the second embodiment, before the step S30, the method further includes:
step S210: and after the current test item is executed, judging whether the current test identification is matched with a preset test identification.
It should be noted that the preset test flag may be a test end flag preset by a user. For example, the user presets a test identifier 1 for identifying an idle oil consumption test item, a test identifier 2 for identifying a vehicle speed oil consumption test item, and a test identifier 3 for identifying a working condition oil consumption test item, so that the number of test items that the user wants to perform is 3, and at this time, the user may set the test identifier 3 as a preset test identifier.
Accordingly, the step S30 includes:
step S30': and when the current test identification is successfully matched with the preset test identification, extracting information of the test result to obtain an oil consumption parameter and a battery parameter, and generating an oil consumption test result table according to the oil consumption parameter and the battery parameter.
It should be understood that when the current test identifier is successfully matched with the preset test identifier, it indicates that all the fuel consumption test items preset by the user have been completely tested. At this time, the information of the test result can be directly extracted, the oil consumption parameter and the battery parameter are obtained, and an oil consumption test result table is generated according to the oil consumption parameter and the battery parameter.
Also, for ease of understanding, reference is made to table 1 for illustration:
TABLE 1 oil consumption test result table for vehicle
Further, in order to ensure that all the test items can be executed, after step S210, the method further includes:
and when the matching of the current test identification and the preset test identification fails, adjusting the current test identification, and returning to the step of obtaining the current test identification corresponding to the vehicle to be tested until the matching of the current test identification and the preset test identification is successful.
It should be understood that when the current test identifier fails to match the preset test identifier, it indicates that all the fuel consumption test items preset by the user are not completely tested. At this time, the current test identifier needs to be adjusted, for example, the current test identifier is incremented, and the step of obtaining the current test identifier corresponding to the vehicle to be tested is returned, so that the current test item is determined again, and the test is performed until all test items are completed.
In a second embodiment, after the current test item is executed, whether the current test identifier is matched with a preset test identifier is judged, when the current test identifier is successfully matched with the preset test identifier, information extraction is performed on the test result, an oil consumption parameter and a battery parameter are obtained, and an oil consumption test result table is generated according to the oil consumption parameter and the battery parameter, so that the fact that all test items are executed can be guaranteed, and a complete and accurate oil consumption test result table can be generated.
In addition, an embodiment of the present invention further provides a storage medium, where a vehicle fuel consumption test program is stored on the storage medium, and the vehicle fuel consumption test program, when executed by a processor, implements the steps of the vehicle fuel consumption test method described above.
In addition, referring to fig. 4, an embodiment of the present invention further provides a vehicle fuel consumption testing apparatus, where the vehicle fuel consumption testing apparatus includes: the system comprises an acquisition module 10, a test module 20 and a generation module 30;
the obtaining module 10 is configured to obtain a current test identifier corresponding to a vehicle to be tested when a vehicle oil consumption test instruction is received.
It should be noted that the vehicle oil consumption test instruction may be a control instruction input by a user through a user interaction interface of the vehicle oil consumption test device; or the control instruction may be a control instruction input by the user through a terminal device of the vehicle oil consumption testing device in advance, which is not limited in this embodiment; the test identifier may be identification information preset by a user and used for identifying a test item, for example, the test identifier 1 may be used for identifying an idle oil consumption test item, the test identifier 2 may be used for identifying a vehicle speed oil consumption test item, and the test identifier 3 may be used for identifying a working condition oil consumption test item, which is not limited in this embodiment.
It can be understood that, the obtaining of the current test identifier corresponding to the vehicle to be tested may be searching for the current test identifier corresponding to the vehicle to be tested in a preset storage area, where the preset storage area may be a storage area preset by a user and used for storing identifier information, and this embodiment does not limit this.
The test module 20 is configured to determine a current test item according to the current test identifier, and control the vehicle to be tested to execute the current test item to obtain a test result.
It should be understood that the current test identifier may be at least one of a preset idle fuel consumption test identifier, a preset vehicle speed fuel consumption test identifier, and a preset operating condition fuel consumption test identifier, which is not limited in this embodiment.
In a specific implementation, for example, the preset idle oil consumption test item may be that the vehicle is turned on at idle to discharge until the engine is started and charged, the air conditioner is turned off to start the test, and the test is completed after the engine is stopped after time t.
The vehicle speed test item can be that when the vehicle speed is low, such as 60km/h driving, the fuel consumption meter is connected, the running at a constant speed of 60km/h is tested by using a certain battery electric quantity (SOC), the running is in a pure electric mode when the SOC is higher, the engine is not started, when the SOC is lowered to a certain value (e.g. 25%) the engine starts to drive the tires directly, and the battery is charged, the engine is stopped when the SOC is gradually increased to a certain value (such as 45 percent), the pure electric mode is continuously entered, the above steps are repeated in a circulating way, after about 10 minutes of testing, two points with the same SOC which are far away from each other are taken, taking 25% SOC as an example, take the first point of 25% S0C and the last point of 25% SOC within 10 minutes, the fuel consumption in the period is the constant-speed fuel consumption without the battery charging and discharging factors, and the constant-speed fuel consumption is objectively and truly represented.
When the vehicle speed is high, because the battery is charged and discharged quickly, frequent engine starting and stopping switching is not beneficial to saving oil, therefore, the current test items are that the engine is directly driven, the SOC is controlled at the target SOC, the engine is directly driven and the battery is charged when the SOC is increased to a certain value (such as 75%) and is only driven independently, therefore, the test data is recorded from the moment, the SOC value is still unchanged after about 10 minutes, and the fuel consumption measured in the 10 minutes can represent the actual fuel consumption level of the constant-speed 120km/h driving.
The working condition test items can take WLTC as an example, the vehicle is discharged until the engine is started, the SOC of the vehicle battery is ensured to be about 50%, the SOC of the vehicle battery is fully charged until the vehicle battery cannot be charged, the oil consumption of WLTC heat engine circulation working conditions in three states is respectively tested, and the initial SOC value and the final SOC value are recorded. And comparing the oil consumption difference and the SOC difference of the three tests to obtain a conversion relation between the SOC and the oil consumption, converting the change of the SOC into the change of the oil consumption in the results of the three tests, finally obtaining the final oil consumption test result of the three tests after eliminating the influence of the SOC, and taking the average value as the WLTC heat engine cycle working condition oil consumption of the vehicle.
The generating module 30 is configured to extract information of the test result, obtain an oil consumption parameter and a battery parameter, and generate an oil consumption test result table according to the oil consumption parameter and the battery parameter.
It should be understood that the extracting of the information of the test result to obtain the fuel consumption parameter and the battery parameter may be extracting the identifier of the test result to obtain the information identifier, and screening the test result according to the information identifier to obtain the fuel consumption parameter and the battery parameter.
It can be understood that the generating of the fuel consumption test result according to the fuel consumption parameter and the battery parameter may be generating a fuel consumption test result table according to the fuel consumption parameter and the battery parameter through a preset table template, where the preset fuel consumption test result table may be a table preset by a user.
