Description

Technical Field

[0001] The present invention relates to the field of vehicles, and in particular to a testing process for the warm air performance of a parking air conditioner, as well as a testing device and a computer program product for the warm air performance of a parking air conditioner. Background Art

[0002] In the related art, since the vehicle is equipped with an independent heat source, the vehicle parking air conditioner can turn on the heating in winter without starting the vehicle. It is necessary to conduct a separate functional test on the production line and automatically record the results to avoid poor heating caused by parking air conditioner problems. The current test of the parking air conditioner heating performance cannot determine whether the oil pump can work normally to provide fuel for the independent heat source. When the oil pump cannot provide fuel for the independent heat source, it will cause dry burning. At the same time, when testing the parking air conditioner, the program will select the corresponding test standard according to different outdoor temperatures. If the test standard is met, the test is successful. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the present invention is to provide a test process for the heating performance of a parking air conditioner, which can determine whether the oil pump provides fuel for an independent heat source by observing an observation window set at a preset position of the oil pipe when testing the heating performance of the parking air conditioner, thereby avoiding damage to the device caused by dry burning due to misoperation and improving test safety.

[0004] The second object of the present invention is to provide a testing device for the heating performance of a parking air conditioner.

[0005] The third object of the present invention is to provide a computer program product.

[0006] In order to solve the above problems, an embodiment of the first aspect of the present invention provides a testing process for the heating performance of a parking air conditioner. When the vehicle is parked, the coolant of the parking air conditioner is heated by an independent heat source of the vehicle to provide warm air. The independent heat source is connected to an oil pump through an oil pipe. The oil pump is used to provide fuel in a container to the independent heat source to generate heat. The testing process includes: the vehicle is in a parking state; starting the oil pump is determined according to a user operation instruction, and the running time of the oil pump is recorded; when the running time reaches a time threshold, the fuel amount is confirmed according to the fuel in the oil pipe at the connection between the oil pump and the independent heat source and the fuel level sensor in the independent heat source, so as to achieve the purpose of testing the oil pump.

[0007] According to the testing process of the parking air conditioner heating performance of an embodiment of the present invention, when testing the parking air conditioner heating performance, it can be determined whether the oil pump provides fuel as an independent heat source by observing the observation window set at a preset position of the oil pipe. When the oil pump running time reaches a time threshold and fuel is observed in the oil pipe, the parking air conditioner heating performance is tested. If the oil pump running time reaches the time threshold and no fuel is observed in the oil pipe, or if no fuel is observed in the oil pipe during the test or the oil level sensor reports an error, the test is stopped immediately to avoid damage to the device due to dry burning caused by misoperation and to improve test safety.

[0008] In some embodiments, the oil pump is tested based on the fuel in the oil pipe where the oil pump is connected to the independent heat source, including: when the presence of fuel and / or the oil level is below a threshold condition is observed in the oil pipe, the oil pump is controlled to stop working, and the test of the oil pump passes.

[0009] In some embodiments, when it is observed that there is no fuel and / or the oil level threshold condition is not reached in the oil pipe where the oil pump is connected to the independent heat source, the oil pump is controlled to be turned off. If the fuel amount in the fuel level sensor is lower than the fuel threshold, the oil pump is started again to determine the fuel in the oil pipe where the oil pump is connected to the independent heat source. If there is no fuel in the oil pipe, it is determined that the oil pump is abnormal and the test is stopped immediately.

[0010] In some embodiments, the testing process also includes: after the oil pump test is passed, reconfirming the coolant temperature and coolant level threshold conditions; when the coolant temperature is higher than the temperature threshold and the coolant level is lower than the threshold condition due to engine start-up in actual work, the test cannot be performed; if the coolant temperature is lower than the temperature threshold and the coolant level reaches the threshold condition, controlling the oil pump to run and controlling the parking air conditioner to turn on; collecting the coolant temperature and air outlet temperature of the parking air conditioner; and determining whether the parking air conditioner meets the parking warm air standard based on the coolant temperature and the air outlet temperature.

[0011] In some embodiments, determining whether the parking air conditioner meets the parking warm air standard is based on the coolant temperature and the air outlet temperature, including: compared with before the parking air conditioner is started, the increase in the coolant temperature reaches a threshold and the increase in the air outlet temperature reaches an air outlet temperature threshold, determining that the parking air conditioner meets the parking warm air standard.

[0012] In some embodiments, when the initial temperature of the coolant reaches 60 degrees or the coolant level is lower than a threshold condition, the parking air conditioner and the oil pump are controlled to stop working to stop the test. An initial temperature higher than 60 degrees will result in the coolant failing the test even after being heated for a long time; a coolant level that is too low will cause dry burning, posing a serious safety hazard.

[0013] In some embodiments, the testing process further includes: storing various test data of the oil pump and the parking air conditioner.

[0014] In some embodiments, the testing process further comprises: in response to a printing instruction, outputting the test data for printing.

[0016] According to the parking air conditioner heating performance testing device of the embodiment of the present invention, the corresponding parking air conditioner heating performance test program can be stored in the memory. When the parking air conditioner heating performance is tested, the processor runs the program in the memory, and the test results are automatically saved and printed, thereby improving the test efficiency and avoiding errors in recording the test results.

[0017] A third aspect of the present invention provides a computer program product, which is configured with a computer program. When the computer program is executed, it implements the testing process of the parking air conditioner heating performance described in the above embodiment.

[0021] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0022] A first aspect of an embodiment of the present invention provides a testing process for the heating performance of a parking air conditioner. When the vehicle is parked, the coolant of the parking air conditioner is heated by an independent heat source of the vehicle to provide warm air. The independent heat source is connected to an oil pump via an oil pipe. The oil pump is used to provide fuel in a container to the independent heat source to generate heat. When testing the heating performance of the parking air conditioner, the testing process can determine whether the oil pump provides fuel to the independent heat source by observing an observation window set at a preset position of the oil pipe, thereby avoiding damage to the device caused by dry burning due to misoperation and improving test safety.

[0023] Reference below Figure 1 A vehicle control method according to an embodiment of the first aspect of the present invention is described as follows: Figure 1 As shown, the method at least includes steps S1 to S3.

[0024] Step S1, the vehicle is in parking state.

[0025] Specifically, when the vehicle is driving, the engine is running, and the high-temperature coolant in the engine will flow through the heater tank. At this time, the wind blown by the blower will also pass through the heater tank, so that warm air will be blown out of the air outlet of the car air conditioner, and the large amount of heat energy generated during the operation of the engine is utilized. The coolant is used as a heat carrier to release the heat energy in the vehicle space to achieve heating. After the vehicle is separately configured with an independent heat source, the vehicle's parking air conditioner can turn on the heater without starting the vehicle in winter. Therefore, when testing the parking air conditioner heating performance, there is no need to start the vehicle, and the parking air conditioner heating performance is tested when the vehicle is in the parked state.

[0026] Step S2, starting the oil pump according to the user's operation instruction, and recording the running time of the oil pump.

[0027] Specifically, after starting to test the parking air conditioning heating performance, the oil pump is started first according to the user's operating instructions. At this time, the test interface displays whether to start the oil pump. After the user clicks to turn on the oil pump, the oil pump starts and records the running time of the oil pump. If the oil pump can run for 60 seconds, the oil chamber can be filled by default.

[0028] Step S3, when the running time reaches the threshold of 60 seconds, the fuel amount is confirmed based on the fuel in the oil pipe at the connection between the oil pump and the independent heat source and the fuel level sensor in the independent heat source. Normal oil amount indicates that the oil pump is working normally, thus achieving the purpose of testing the oil pump.

[0029] Specifically, an oil level sensor is provided in the oil pipe. After the oil pump starts working, the oil level sensor detects whether there is fuel flowing in the oil pipe. After detecting that there is fuel flowing in the oil pipe and the oil level sensor has no error, the test can start. The time threshold for testing whether the oil pump can operate normally can be set to 60 seconds. The independent heat source is provided with a fuel storage tank. The fuel storage tank can store the fuel provided within 40 seconds of the operation of the oil pump. Since an observation window is provided at a preset position of the oil pipe where the oil pump is connected to the independent heat source, fuel can be observed in the oil pipe after the oil pump has been running for 40 seconds. The time threshold for testing whether the oil pump can operate normally is set to 60 seconds to leave redundancy, so as to ensure that sufficient fuel is provided for the independent heat source.

[0030] According to the testing process of the parking air conditioner heating performance of an embodiment of the present invention, when testing the parking air conditioner heating performance, it can be determined whether the oil pump provides fuel as an independent heat source by observing the observation window set at a preset position of the oil pipe. When the oil pump running time reaches a time threshold and fuel is observed in the oil pipe, the parking air conditioner heating performance is tested. If the oil pump running time reaches the time threshold and no fuel is observed in the oil pipe, or if no fuel is observed in the oil pipe during the test or the oil level sensor reports an error, the test is stopped immediately to avoid damage to the device due to dry burning caused by misoperation and to improve test safety.

[0031] In some embodiments, the oil pump is tested based on the fuel in the oil pipe where the oil pump is connected to the independent heat source, including: when the presence of fuel is observed in the oil pipe and / or the oil level threshold condition is reached, the oil pump is controlled to stop working, and the test of the oil pump passes.

[0032] Specifically, after starting to test the parking air conditioning heating performance, the oil pump is started first according to the user's operating instructions. At this time, the test interface displays whether to start the oil pump. After the user clicks to turn on the oil pump, the oil pump starts and records the running time of the oil pump. If the oil pump can be tested for 60 seconds and there is fuel in the oil pipe where the oil pump is connected to the independent heat source, it means that the oil pump can operate normally. The user clicks on the test interface that the oil pump can operate normally, and the test software saves the result.

[0033] In some embodiments, the oil pump is tested based on the fuel in the oil pipe where the oil pump is connected to the independent heat source, including: when it is observed that there is no fuel and / or the oil level threshold condition is not reached in the oil pipe where the oil pump is connected to the independent heat source, the oil pump is controlled to be turned off; if the fuel amount in the fuel level sensor is lower than the threshold, the oil pump is started again to determine the fuel in the oil pipe where the oil pump is connected to the independent heat source; if there is no fuel in the oil pipe, it is determined that the oil pump is abnormal and the test is stopped immediately.

[0034] Specifically, if no fuel can be observed in the oil pipe observation window at the connection between the oil pump and the independent heat source after 60 seconds of trial operation, or the fuel level sensor is below the threshold, the oil pump is controlled to shut down and started again. After 60 seconds, observe again whether there is fuel in the oil pipe at the connection between the oil pump and the independent heat source. If there is no fuel in the oil pipe, it is determined that the oil pump is abnormal or the fuel level sensor is below the threshold. The user clicks on the test interface that the oil pump cannot operate normally, and the test software saves the result.

[0035] In some embodiments, Figure 2 As shown, the testing process further includes steps S3 to S6.

[0036] Step S4, after the oil pump test is passed, the coolant temperature and coolant level threshold conditions are confirmed again. Since the engine is started in actual work, when the coolant temperature is higher than the temperature threshold and the coolant level is lower than the threshold condition, the test cannot be performed. If the coolant temperature is lower than the temperature threshold and the coolant level reaches the threshold condition, the oil pump is controlled to run and the parking air conditioner is controlled to start; Specifically, the functional test of the oil pump is an important prerequisite, which ensures that the oil pump can stably and safely provide the required fuel pressure under normal working conditions. After the oil pump test is passed, the coolant temperature and coolant level threshold conditions are judged. The coolant temperature threshold can be 60°C. The coolant level is obtained through the level sensor. When the coolant temperature is lower than the temperature threshold and the coolant level reaches the threshold condition, it is determined that the parking air conditioner is powered on normally, and the oil pump is controlled to run and the parking air conditioner is turned on. The oil pump and the parking air conditioner are operated at the same time to avoid dry burning of the independent heat source due to insufficient fuel supply of the oil pump, which causes damage to the device and makes the parking air conditioner unable to work normally; if the oil pump fails during operation, it is necessary to conduct timely troubleshooting and processing, check the working status of sensors, actuators, controllers and other components, and replace damaged parts.

[0037] Step S5, collecting the coolant temperature and air outlet temperature of the parking air conditioner.

[0038] Specifically, after the oil pump test passes, the oil pump is controlled to run and the parking air conditioner is controlled to turn on, and the coolant temperature and air outlet temperature of the parking air conditioner are collected. The test software records the collected coolant temperature and air outlet temperature data, including the measurement time, environmental conditions and setting parameters of the parking air conditioner.

[0039] Step S6, determining whether the parking air conditioner meets the parking heating standard according to the coolant temperature and the air outlet temperature.

[0040] First, identify the outdoor temperature, determine the temperature range by reading the temperature of the outdoor temperature sensor, and select the corresponding detection threshold according to the temperature range, as shown in Table 1: Table 1 Coolant temperature threshold comparison table

[0041] Specifically, the performance and working status of the parking air conditioner are analyzed based on the collected data, and the heating efficiency of the parking air conditioner can be evaluated by comparing the changing trends of the coolant temperature and the air outlet temperature; Normally, it applies to scenario 2. After the parking air conditioner is turned on for a period of time, the coolant temperature rises by 20 degrees and the air outlet temperature rises by 12 degrees, indicating that the parking air conditioner meets the parking warm air standard. The test software records the data to provide support for subsequent analysis and decision-making.

[0042] According to actual experience, the coolant temperature is mostly between 30℃ and 40℃ in summer. At this time, the program will automatically detect the outdoor temperature when running, automatically select scenario 1, read the coolant temperature and the air outlet temperature, and if the coolant temperature rises by more than 10℃ and the air outlet temperature rises by more than 5℃, the parking air conditioner meets the parking warm air standard, and the test is passed. This method can shorten the actual test time in summer and reduce the failure rate. For example, the running time of each program can be reduced by 5 minutes during summer testing, and the failure rate can be reduced by 30%; When the outdoor temperature is higher than 40 degrees Celsius, in order to prevent heat stroke, the driver must leave the cab before testing, and the temperature threshold is lowered, which is applicable to scenario 3 to prevent heat stroke caused by overheating of the cab. This method not only avoids test failures caused by hot summer temperatures and long test times, but also avoids heat stroke caused by the driver due to high temperatures.

[0043] In some embodiments, the test process further includes: when the initial temperature of the coolant reaches a temperature threshold of 60° C. or the coolant level is lower than a threshold condition, controlling the parking air conditioner and the oil pump to stop working and stopping the test.

[0044] Specifically, after the oil pump test passes, the oil pump is controlled to run and the parking air conditioner is turned on. The test software reads the temperature sensor information in real time. When the coolant temperature reaches 60°C or the coolant level is lower than the threshold condition, the test is stopped to avoid excessive temperature, which prevents the target temperature from being reached, resulting in a long test time and test failure. At the same time, if there is a lack of coolant, dry burning will occur, posing a safety hazard. In the actual production process, it is often impossible to add coolant due to cooling system failure. Therefore, the program reads the coolant level at the same time and performs the test when the level is normal, avoiding similar risks.

[0045] In some embodiments, the testing process further includes: storing various test data of the oil pump and the parking air conditioner.

[0046] Specifically, at the end of the parking air conditioner heating performance test, the test software stores various test data of the oil pump and the parking air conditioner to ensure the accuracy and completeness of the data, such as whether the oil pump can operate normally, the coolant temperature and the air outlet temperature at different times, and generates a table to determine whether the parking air conditioner heating performance is qualified.

[0047] In some embodiments, the testing process further includes: in response to a printing instruction, outputting the test data for printing.

[0048] Specifically, the test software stores various test data of the oil pump and parking air conditioner to ensure the accuracy and completeness of the data. After receiving the print command, the test data is output in the form of a table for printing. There is no need to manually record the test data, thus avoiding errors in recording test results and improving test efficiency.

[0049] Reference below Figure 3 The test steps of the parking air conditioner heating performance according to the embodiment of the present invention are described by way of example, and the specific contents are as follows.

[0050] Step S7, the diagnostic instrument reads the vehicle status information through the body control module.

[0051] Step S8, determining whether the vehicle is in a parking state; if so, executing step S9, otherwise, executing step S15.

[0052] Step S9: the oil pump control module starts to control the oil pump to pump oil.

[0053] Step S10, determine whether the standard oil level is reached; if so, execute step S11, otherwise, execute step S15.

[0054] Step S11, reading the coolant temperature and coolant level.

[0055] Step S12, determine whether the coolant temperature is lower than 60°C and the coolant level reaches a threshold condition; if so, execute step S13, otherwise, execute step S15.

[0056] Step S13, determining the temperature difference standard according to the ambient temperature.

[0057] Step S14, determine whether the temperature difference standard is within the standard range; if so, execute step S16, otherwise, execute step S15.

[0058] Step S15, test failed.

[0059] Step S16, the test is successful.
