Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a vehicle dew point control method, device, electronic equipment, medium and program product. Background Art

[0002] At the beginning of vehicle startup, water vapor in the exhaust system may condense into water due to the low system temperature. This may cause the ceramic body of the oxygen sensor to explode due to contact with condensed water. To avoid this, it is necessary to monitor the temperature of the oxygen sensor and its vicinity, as well as the temperature of the exhaust system pipe wall.

[0003] The temperature at which the condensation and evaporation of water vapor in the system are delayed or the rate of increase slows down is called the dew point temperature. It is generally believed that when the system reaches the dew point temperature, water vapor no longer condenses or evaporates, and the oxygen sensor can be safely heated at full power. To achieve this, an over-dew point flag is usually set to indicate whether the system has exceeded the dew point temperature.

[0004] However, the actual triggering of the over-dew point flag set in the relevant technology may be affected by factors such as the amplification correction of the heat integral limit and the application of the safety factor, resulting in a delayed setting of the over-dew point flag, thereby affecting the protection mechanism and test efficiency of the oxygen sensor, increasing test time and cost, and hindering the calibration of the emission module.

[0025] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0026] The following describes the dew point control method, device, electronic device, medium and program product of the vehicle of the embodiment of the present application with reference to the accompanying drawings. In view of the problem that the over-dew point flag is delayed in setting mentioned in the above background technology, which affects the protection mechanism and test efficiency of the oxygen sensor, increases the test time and cost, and hinders the calibration work of the emission module, the present application provides a dew point control method for a vehicle, in which the over-dew point flag is obtained and controlled according to the dew point control calibration amount and the current heat integral value in the exhaust pipe by manually inputting the dew point control calibration amount during the vehicle dew point control calibration test, and finally the vehicle dew point control calibration test is controlled to end according to the over-dew point flag, which saves the test time of the dew point control calibration and improves the efficiency of the calibration work; reduces the emission of pollutants and protects the ecological environment. Thus, the problem that the over-dew point flag position of the vehicle is uncontrollable, affects the protection mechanism and test efficiency of the oxygen sensor, increases the test time and cost, and hinders the calibration work of the emission module is solved.

[0027] Specifically, Figure 1 A schematic flow chart of a dew point control method for a vehicle provided in an embodiment of the present application.

[0028] like Figure 1 As shown, the dew point control method of the vehicle includes the following steps:

[0029] In step S101, a dew point control calibration amount manually input during a vehicle dew point control calibration test is obtained.

[0030] It can be understood that when the dew point control method of the vehicle starts, the embodiment of the present application first obtains the dew point control calibration amount, and the dew point control calibration amount is manually input when the vehicle performs a dew point control calibration test.

[0031] In an embodiment of the present application, the dew point control calibration amount includes a setting calibration amount and a correction calibration amount, wherein the setting calibration amount sets the over-dew point flag, and the correction calibration amount corrects the heat integral limit in the exhaust pipe.

[0032] Among them, the set calibration quantity can be time, which can be achieved through a timer or other methods. For example, if time is used as the set calibration quantity, 8 minutes can be manually input, and the over-dew point flag can be automatically set to 1 after 8 minutes; the over-dew point flag has a value of 0 or 1. When the output over-dew point flag is 0, in order to protect the oxygen sensor, the set heat integral value of the next start will be increased by 25%. When the output over-dew point flag is 1, the test process ends; the correction calibration quantity is used to correct the heat integral limit in the exhaust pipe, and it needs to be manually input before the test starts; the heat integral limit in the exhaust pipe refers to the maximum heat value allowed to accumulate inside the exhaust pipe.

[0033] It can be understood that the embodiment of the present application can manually input a suitable dew point control calibration quantity, including a setting calibration quantity and a correction calibration quantity. During the experiment, the over-dew point mark position is set and the heat integral limit in the exhaust pipe is corrected according to the setting calibration quantity and the correction calibration quantity, so as to achieve the over-dew point mark position 1 within the expected range and correct the heat integral limit.

[0034] In an embodiment of the present application, obtaining the dew point control calibration amount manually input during the vehicle dew point control calibration test includes: manually inputting the setting calibration amount, or inputting the setting calibration amount after a preset time from the start time of the vehicle dew point control calibration test.

[0035] Among them, the preset duration can be set according to different test requirements and test vehicle models, and is not specifically limited here.

[0036] It is understandable that in the embodiment of the present application, the position calibration amount can be manually input based on the engineer's experience and judgment before the test, or a period of time can be preset, starting from the start of the test, and the position calibration amount can be input after the preset period of time is reached.

[0037] In an embodiment of the present application, before the vehicle dew point control calibration test begins, a preset calibration duration and a correction calibration amount are calibrated according to the vehicle model.

[0038] Among them, different models use different sensors, engine start time and engine temperature rise, so it is necessary to calibrate the preset time and correct the calibration amount according to the model. The preset time can be actually set or calibrated without specific limitation.

[0039] It is understandable that in the embodiment of the present application, before the vehicle dew point control calibration test begins, the manually input preset duration and correction calibration amount need to be determined with reference to the vehicle model.

[0040] In step S102, the dew point flag is controlled according to the dew point control calibration amount and the current heat integral value in the exhaust pipe.

[0041] It is understandable that the embodiment of the present application can monitor the current heat integral value in the exhaust pipe, and control the dew point flag through the input dew point control calibration amount and the current heat integral value in the exhaust pipe.

[0042] In an embodiment of the present application, the over-dew point flag is controlled according to the dew point control calibration amount and the current heat integral value in the exhaust pipe, including: if the dew point control calibration amount is a set calibration amount, the over-dew point flag is output; if the dew point control calibration amount is a corrected calibration amount, the heat integral limit is corrected according to the corrected calibration amount, and when the current heat integral value exceeds the corrected heat integral limit, the over-dew point flag is output.

[0043] It can be understood that in the embodiment of the present application, the input dew point control calibration value is identified, and when the dew point control calibration value is the set calibration value, the over-dew point flag is output, that is, the over-dew point flag position is 1; when the dew point control calibration value is the corrected calibration value, the heat integral limit is corrected according to the corrected calibration value, and the current heat integral value in the exhaust pipe is continued to be monitored. When it is detected that the current heat integral value exceeds the corrected heat integral limit, the over-dew point flag is output, that is, the over-dew point flag position is 1.

[0044] For example, the dew point control calibration quantity obtained in the embodiment of the present application is a set calibration quantity, and its content is that the dew point mark position is 1 after 8 minutes. When the test time reaches 8 minutes, the over-dew point mark position is output, that is, the over-dew point mark position is 1; the dew point control calibration quantity obtained is a correction calibration quantity, and the heat integral limit is corrected according to the input correction calibration quantity, and the corrected heat integral limit is used as the judgment standard. When it is detected that the current heat integral value exceeds the corrected heat integral limit, the over-dew point flag position is output, that is, the over-dew point flag position is 1.

[0045] In the embodiment of the present application, when the dew point control calibration amount is the set calibration amount, before outputting the over-dew point flag, it also includes: if the current heat integral value exceeds the heat integral limit, then outputting the over-dew point flag.

[0046] It can be understood that in the embodiment of the present application, if the current heat integral value has exceeded the heat integral limit before the set calibration amount is reached, it means that the temperature has reached the dew point temperature and the dew point flag position needs to be set to 1, then the dew point flag position is output.

[0047] For example, the dew point control calibration quantity input in the embodiment of the present application is a set calibration quantity, and the content is that the over-dew point flag position is 1 after 8 minutes. 6 minutes after the start of the test, it is detected that the current heat integral value has exceeded the heat integral limit, then the over-dew point flag position is set to 1, and the over-dew point flag position is output.

[0048] In step S103, the vehicle dew point control calibration test is terminated according to the over-dew point flag.

[0049] Among them, when the output over-dew point flag is 0, in order to protect the oxygen sensor, the set heat integral value of the next start will be increased by 25%; when the output over-dew point flag is 1, the test process is terminated.

[0050] It can be understood that in the embodiment of the present application, when the output over-dew point flag is 0, the next vehicle dew point control calibration test is started. In order to protect the oxygen sensor, the set heat integral value for the next start will be increased by 25%; when the output over-dew point flag is 1, the vehicle dew point control calibration test is ended.

[0051] According to the vehicle dew point control method proposed in the embodiment of the present application, the dew point control calibration amount manually input during the vehicle dew point control calibration test is used to obtain and control the over-dew point flag according to the dew point control calibration amount and the current heat integral value in the exhaust pipe, and finally the vehicle dew point control calibration test is ended according to the over-dew point flag, so that the dew point flag position can be flexibly controlled, making the dew point flag position controllable and improving the test efficiency. Thus, the problem of the vehicle over-dew point flag position being uncontrollable, affecting the protection mechanism and test efficiency of the oxygen sensor, increasing the test time and cost, and hindering the calibration work of the emission module is solved.

[0052] Combine the following Figure 2 As a comparison, the determination of the over-dew point flag in the dew point control logic in the related art is basically completely dependent on the calibrated heat integral limit map. Normally, when the current heat integral value exceeds the value of the corresponding temperature point in the calibrated heat integral limit map, the over-dew point determination condition is met. However, the start in the test is often not under normal circumstances, and is often accompanied by repeated starts that did not pass the dew point last time, and amplification correction is performed. Figure 2 As shown, the method for positioning the over-dew point flag in the related art includes the following steps:

[0053] Step S201: Obtain the current calorie integral value.

[0054] Step S202: Obtain the value of the corresponding temperature point in the heat integral limit map.

[0055] Step S203: compare the current heat integral value with the value of the corresponding temperature point in the heat integral limit map. If the current heat integral value is greater than or equal to the value of the corresponding temperature point in the heat integral limit map, proceed to step S204.

[0056] Step S204: Determine whether the original over-dew point determination condition is met.

[0057] Step S205: obtain the original over-dew point flag position 0 or set it to 1. When the original over-dew point flag position is 0, proceed to step S206. When the original over-dew point flag position is 1, end the vehicle dew point control calibration test.

[0058] Step S206: Correct the heat integral limit value so that the set heat integral value for the next start-up will increase by 25%.

[0059] However, Figure 2In the above-described related art, the over-dew point flag position setting method is uncontrollable. In order to achieve controllable over-dew point flag setting, the embodiment of the present application can add a manually input calibration amount after the over-dew point determination condition, or add a manually input calibration amount before correcting the heat integral limit map, thereby achieving controllable over-dew point flag setting. The dew point control method of the vehicle of the embodiment of the present application will be described below through two specific embodiments, as follows:

[0060] The first embodiment, the embodiment of the present application is to realize the controllability of the over-dew point flag setting, that is, a manually input calibration quantity is added after the over-dew point judgment condition, and the calibration quantity and the output value of the original over-dew point judgment condition are passed through an OR gate together. The default input value of the calibration quantity is 0. When the calibration quantity is set to 1, the over-dew point flag set to 1 can be directly output. Figure 3 As shown, the method of the embodiment of the present application includes the following steps:

[0061] Step S301: Obtain the current calorie integral value.

[0062] Step S302: Obtain the value of the corresponding temperature point in the heat integral limit map.

[0063] Step S303: compare the current heat integral value with the value of the corresponding temperature point in the heat integral limit map. If the current heat integral value is greater than or equal to the value of the corresponding temperature point in the heat integral limit map, proceed to step S304.

[0064] Step S304: determine whether the original over-dew point determination condition is met, and obtain the original over-dew point flag position 0 or set it to 1.

[0065] Step S305: Determine the input condition through manual dew point determination, and obtain the calibration quantity and set it to 0 or 1.

[0066] Step S306: perform an OR operation on the original over-dew point flag and the calibration value obtained through manual input condition determination, and the output value is used as a new over-dew point flag.

[0067] Step S307: When the new over-dew point flag position is 0, proceed to step S308; when the new over-dew point flag position is 1, the vehicle dew point control calibration test is terminated.

[0068] Step S308: Correct the heat integral limit value so that the set heat integral value for the next start-up will increase by 25%.

[0069] In the second embodiment, the embodiment of the present application can be controlled by a flow chart of a dew point control method to determine whether to make corrections. This method adds a manually input calibration amount before correcting the heat integral limit map in the process, so that engineers can determine whether the map needs to be corrected for safety reasons in the current state. By removing the correction process, the condition for the dew point setting in this test is to exceed the heat integral limit calibrated by the engineer; it should be noted that this calibration amount needs to be input before the test begins. Figure 4 As shown, the method of the embodiment of the present application includes the following steps:

[0070] Step S401: The heat integral limit value of the last test is corrected to increase the starting set heat integral value by 25%.

[0071] Step S402: Determine whether the heat integral limit map needs to be corrected by manually judging the input conditions. If not, maintain the heat integral value after increasing it by 25%. If correction is required, remove the previous 25% increase correction and use the heat integral limit pre-calibrated by the engineer as the condition for setting the dew point in this test.

[0072] Step S403: Obtain the current calorie integral value.

[0073] Step S404: Obtain the value of the corresponding temperature point in the corrected heat integral limit map.

[0074] Step S405: compare the current heat integral value with the value of the corresponding temperature point in the heat integral limit map. If the current heat integral value is greater than or equal to the value of the corresponding temperature point in the heat integral limit map, proceed to step S406.

[0075] Step S406: Determine whether the original over-dew point determination condition is met, and obtain the original over-dew point flag position 0 or set it to 1.

[0076] Step S407: Through the OR gate, the over-dew point flag is set to 0 or 1. Since the calibration value of the manual dew point determination is 0 by default, the over-dew point flag obtained through the OR gate is the same as the original over-dew point flag.

[0077] Step S408: When the over-dew point flag is set to 0, step S401 is performed; when the over-dew point flag is set to 1, the vehicle dew point control calibration test is terminated.

[0078] Next, the dew point control device for a vehicle proposed in accordance with an embodiment of the present application will be described with reference to the accompanying drawings.

[0079] Figure 5 It is a block diagram of a dew point control device for a vehicle according to an embodiment of the present application.

[0080] like Figure 5As shown, the dew point control device 10 of the vehicle includes: an acquisition module 501 , a first control module 502 and a second control module 503 .

[0081] Among them, the acquisition module 501 is used to obtain the dew point control calibration value manually input during the vehicle dew point control calibration test; the first control module 502 is used to control the over-dew point flag according to the dew point control calibration value and the current heat integral value in the exhaust pipe; the second control module 503 is used to control the end of the vehicle dew point control calibration test according to the over-dew point flag.

[0082] In an embodiment of the present application, the dew point control calibration amount includes a setting calibration amount and a correction calibration amount, wherein the setting calibration amount sets the over-dew point flag, and the correction calibration amount corrects the heat integral limit in the exhaust pipe.

[0083] In the embodiment of the present application, the acquisition module 501 is further used to: manually input the position calibration amount, or input the position calibration amount after a preset time from the start of the vehicle dew point control calibration test.

[0084] In an embodiment of the present application, before the vehicle dew point control calibration test begins, a preset calibration duration and a correction calibration amount are calibrated according to the vehicle model.

[0085] In the embodiment of the present application, the first control module 502 is further used to: if the dew point control calibration quantity is a set calibration quantity, then output an over-dew point flag; if the dew point control calibration quantity is a corrected calibration quantity, then correct the heat integral limit according to the corrected calibration quantity, and output an over-dew point flag when the current heat integral value exceeds the corrected heat integral limit.

[0086] In the embodiment of the present application, when the dew point control calibration amount is the set calibration amount, before outputting the over-dew point flag, it also includes: if the current heat integral value exceeds the heat integral limit, then outputting the over-dew point flag.

[0087] It should be noted that the above explanation of the embodiment of the dew point control method for a vehicle is also applicable to the dew point control device for a vehicle of this embodiment, and will not be repeated here.

Thus, the problem of the vehicle over-dew point flag position being uncontrollable, affecting the protection mechanism and test efficiency of the oxygen sensor, increasing the test time and cost, and hindering the calibration work of the emission module is solved.
