Description

Technical Field

[0001] This invention relates to the field of intercooler technology, and in particular to an intercooler fault control method, apparatus, equipment, and medium. Background Technology

[0002] The intercooler is one of the important components in a car. Its function is to cool the boosted air, reduce the intake air temperature after boosting, and improve the engine's air exchange efficiency. The main factors affecting the intercooler's efficiency during operation include intake and exhaust temperatures, intake and exhaust pressures, humidity, and intake and exhaust pressures.

[0003] However, it is now common for high intercooler pressure to cause intercooler pipes to burst, leading to engine afterburning, damage to the catalytic converter, and the risk of spontaneous combustion due to abnormally high temperatures emanating from the catalytic converter. Additionally, leaking intercooler filters can cause water to flow into the cylinders and damage the engine. Therefore, it is crucial to promptly identify and control the causes of intercooler failures before they occur. Summary of the Invention

[0004] This invention provides a method, apparatus, equipment, and medium for intercooler fault control, in order to solve the problems of intercooler failure leading to intercooler pipe rupture, engine afterburning, catalytic converter burnout, and the risk of vehicle spontaneous combustion due to abnormal high temperature radiation from the catalytic converter. At the same time, intercooler filter leakage can cause water to flow into the cylinder and damage the engine.

[0019] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the intercooler fault control method according to any embodiment of the present invention.

[0020] The technical solution of this invention determines the intercooler control level based on the vehicle's current road information and driving power demand information. This step, determining the control level based on the current road information, maximizes vehicle utilization. The solenoid valve opening parameters are determined based on the intercooler control level. This step, by determining the solenoid valve opening based on the control level, enables control of the solenoid valve flow according to actual needs, avoiding resource waste. Intercooler control information is determined by comparing the intercooler temperature and ambient temperature with preset temperatures, the intercooler humidity and ambient humidity with preset humidity, and the intercooler pressure and ambient pressure with preset pressures.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0032] Example 1

[0033] Figure 1 This is a flowchart of an intercooler fault control method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations involving intercooler faults. The method can be executed by an intercooler fault control device, which can be implemented in hardware and / or software and can be configured in a vehicle terminal. Figure 1 As shown, the method includes:

[0034] S110. Determine the intercooler control level based on the vehicle's current road information and driving power demand information.

[0035] The current driving road information can be any information indicating the current road type, and can be in data, image, or video format, with no specific limitations on the format. This information may include ambient temperature, map navigation data, coolant temperature, intercooler intake and exhaust pipe temperatures, humidity, and pressure. This information can be obtained through devices capable of providing road segment information, such as in-vehicle cameras and map navigation systems. Driving demand power information characterizes the driver's current driving needs. For example, driving demand power information is determined based on the driver's throttle opening.

[0036] Specifically, the map navigation system collects real-time information about the vehicle's current road, determines the type of the current road segment based on this information, and determines the required power output based on the vehicle's current engine speed and the driver's throttle control. Finally, it combines the road segment type information and the required power output to determine the intercooler control level. For example, the road segment type information includes road gradient and road surface adhesion information.

[0037] Specifically, a pre-established correspondence between different current road conditions and driver power requirements and the intercooler control level is established. Then, based on this correspondence and the actual driving conditions, the current intercooler control level is determined. Determining the degree of intercooler control based on the vehicle's current driving situation improves the accuracy of intercooler control. For example, when the map navigation displays a highway or uphill section with a gradient greater than a preset gradient and the driver's power requirement is >70%, the control level is D1. When the map navigation exits the above road section, if the driver's power requirement is between 30% and 70%, the control level is D2. When the driver's power requirement is <30%, the control level is D3.

[0038] The map navigation provides information including altitude, slope, and latitude / longitude. Altitude information can serve as additional input for the driver's power demand, determining the change in intercooler demand caused by the increase in altitude. This allows for advance detection of intercooler parameters to assess the intercooler's condition. The driving power demand refers to the power required for the vehicle to operate normally on the current road.

[0039] S120. Determine the battery valve opening parameters based on the intercooler control level.

[0040] Among them, the solenoid valve opening parameter can be used to control the opening degree of the solenoid valve. A correspondence between different intercooler control levels and the solenoid valve opening parameter is pre-established based on the intercooler's attribute parameters.

[0041] For example, when the intercooler control level is D1, the solenoid valve opening is 100%; when the intercooler control level is D2, the solenoid valve opening is 50%; and when the intercooler control level is D3, the solenoid valve opening is 20%.

[0042] S130. Based on the comparison results of the intercooler temperature and ambient temperature with the preset temperature, the comparison results of the intercooler humidity and ambient humidity with the preset humidity, and the comparison results of the intercooler pressure and ambient pressure with the preset pressure, determine the intercooler control information; wherein, the intercooler control information includes the solenoid valve control information.

[0043] The preset temperature is determined based on the actual operating conditions of the vehicle's intercooler to ensure its safe operation; the preset humidity is determined based on the actual operating conditions of the vehicle's intercooler to ensure its safe operation; and the preset pressure is determined based on the actual operating conditions of the vehicle's intercooler to ensure its safe operation. Intercooler control information includes controlling target accessories in the vehicle to improve the intercooler's temperature, humidity, and pressure. These target accessories include the solenoid valves in the intercooler, which include coolant flow control solenoid valves and drain control solenoid valves. By determining the solenoid valve control information, corresponding measures are taken for different solenoid valves to accurately control intercooler malfunctions.

[0044] Specifically, the vehicle monitors the temperature, humidity, and pressure of the intercooler, as well as the ambient temperature, humidity, and pressure in real time, compares the monitored data with preset values, determines the current state of the intercooler, and determines control information based on the current state.

[0045] S140. Control the intercooler according to the solenoid valve opening parameters and solenoid valve control information.

[0046] Specifically, the solenoid valve information corresponding to the current intercooler scenario is determined by the solenoid valve control information, and the solenoid valve opening parameters are used to control the solenoid valve in order to control the intercooler malfunction.

[0047] Optionally, the above steps also include:

[0048] The dashboard displays changes in intercooler temperature, humidity, and pressure values ​​to alert the user.

[0049] Specifically, the changes in the temperature, humidity, and pressure values ​​of the intercooler are displayed in real-time as a bar chart. When the temperature, humidity, and pressure are all within the limits, the bar chart is displayed in green; when the real-time values ​​exceed the limits, the bar chart is displayed in red.

[0050] For example, when the intercooler is working normally, the temperature, humidity, and pressure ranges of the intercooler are shown in Table 1:

[0051] Table 1

[0052] Maximum value Minimum value pressure value 250 kPa 100 kPa Temperature value 60℃ 30℃ Humidity value 80％ 5％

[0053] Users can choose to display the following information on the dashboard:

[0054] The temperature, humidity, and pressure values ​​of the intercooler are displayed in real-time as a bar chart. When the temperature, humidity, and pressure are all within the limits, the bar chart is green. When the real-time values ​​exceed the limits, the bar chart is red to remind the user.

[0055] When real-time values ​​exceed limits, the ECU control logic differs depending on the specific limit. When the pressure value exceeds the limit, the ECU controls the engine to run at low speed and low load, stopping the turbocharger and alerting the driver for maintenance. When the temperature value exceeds the limit, the engine controls the solenoid valve to adjust the intercooler temperature and alerts the driver. Once the intercooler temperature returns to within the range, the solenoid valve closes, and the alert is canceled. If the intercooler humidity does not return to within the range after 1 minute, the ECU controls the engine to run at low speed and low load and alerts the driver for maintenance. When the humidity exceeds the limit, the engine controls the solenoid valve to drain water for 1 minute and alerts the driver. Once the intercooler humidity returns to within the range, the solenoid valve closes, and the alert is canceled. If the intercooler humidity does not return to within the range after 1 minute, the ECU controls the engine to run at low speed and low load and alerts the driver for maintenance.

[0056] The technical solution of this invention determines the intercooler control level based on the vehicle's current road information and driving power demand information. This step, determining the control level based on the current road information, maximizes vehicle utilization. The solenoid valve opening parameters are determined based on the intercooler control level. This step, by determining the solenoid valve opening based on the control level, enables control of the solenoid valve flow according to actual needs, avoiding resource waste. Intercooler control information is determined by comparing the intercooler temperature and ambient temperature with preset temperatures, the intercooler humidity and ambient humidity with preset humidity, and the intercooler pressure and ambient pressure with preset pressures. This intercooler control information includes solenoid valve control information. This step uses temperature, humidity, and pressure to determine if there is a fault in the intercooler. If a fault is found, control information is generated promptly to enable timely fault handling by the vehicle. Finally, the intercooler is controlled based on the solenoid valve opening parameters and the solenoid valve control information, ensuring that the intercooler operates within a safe range. This method can determine the control level of the intercooler based on the current vehicle driving information, and can promptly and accurately detect abnormalities in intercooler pressure, humidity, and temperature and take measures. The ECU enters the idling condition, reduces the amount of fuel injected into the engine, and avoids the risk of catalytic converter burnout caused by excessive fuel injection, abnormal high temperature radiation from the catalytic converter causing vehicle spontaneous combustion, and the risk of water accumulation in the cylinder and engine damage caused by intercooler filter leakage.

[0057] Example 2

[0058] Figure 2 This is a flowchart of an intercooler temperature fault control method provided in Embodiment 2 of the present invention. This embodiment is a further elaboration of the above embodiments. Figure 2 As shown, the method includes:

[0059] S210. Determine the intercooler control level based on the vehicle's current road information and driving power demand information.

[0060] S220. Determine the battery valve opening parameters based on the intercooler control level.

[0061] S230. If the intercooler temperature is greater than the first preset temperature and the ambient temperature exceeds the upper limit of the reference ambient temperature range, the intercooler control information is to close the coolant flow control battery valve.

[0062] The first preset temperature can be a maximum temperature value that can be preset to maintain the intercooler's safe operating temperature according to actual needs, such as 60℃. The ambient temperature can be the temperature of the environment surrounding the intercooler, such as 30℃. The reference ambient temperature range can be a range of reference ambient temperature variation set according to the actual ambient temperature when the intercooler is operating, such as 35℃-15℃.

[0063] Specifically, when the intercooler temperature is greater than or equal to the first preset temperature and the ambient temperature is greater than the upper limit of the reference ambient temperature, it is considered that the intercooler temperature is over the limit due to the high ambient temperature. Therefore, the intercooler is considered to be not faulty, and the engine is controlled to run normally without cooling treatment. Thus, the coolant flow control solenoid valve does not open.

[0064] S240. If the intercooler temperature is greater than the first preset temperature, and the ambient temperature is lower than the lower limit of the reference ambient temperature range or within the reference ambient temperature range, then the intercooler control information is to open the coolant flow control battery valve.

[0065] Specifically, if the intercooler temperature is higher than the first preset temperature, and the current ambient temperature is lower than the lower limit of the reference ambient temperature range or within the reference ambient temperature range, then the intercooler temperature exceeding the limit is considered to be caused by an intercooler malfunction, and cooling treatment is required. Therefore, the intercooler control information is updated to open the coolant flow control solenoid valve.

[0066] For example, assuming the first preset temperature is 60°C, the intercooler temperature is 70°C, the ambient temperature is 20°C, and the reference ambient temperature range is 25°C-15°C, if the intercooler temperature is greater than the first preset temperature and the ambient temperature of 20°C is within the reference ambient temperature range, then the intercooler temperature is considered to be out of limit, and the control information of the intercooler is updated to open the coolant flow control solenoid valve.

[0067] The above steps determine whether the intercooler temperature exceeding the limit is due to an increase in the intercooler's own temperature or due to environmental factors by judging the ambient temperature, thus avoiding misjudgment.

[0068] S250: After the solenoid valve is opened according to the solenoid valve opening parameters, the subsequent temperature of the intercooler is determined after a preset time period.

[0069] The preset time period can be a time period for the intercooler to return to its normal temperature range, which can be preset according to the actual situation. For example, the preset time period can be 1 minute.

[0070] Specifically, the solenoid valve opening is controlled by adjusting the coolant flow rate. Once the solenoid valve is open, it cools the intercooler, and the current temperature is measured after 1 minute. Temperature sensors or other temperature-sensing devices can be used to detect the intercooler temperature.

[0071] S260. If the subsequent temperature of the intercooler is greater than the second preset temperature, the intercooler control information is updated to reduce the engine speed and keep the coolant flow control battery valve open; wherein, the second preset temperature is less than the first preset temperature.

[0072] The second preset temperature can be a temperature that ensures the intercooler is in normal working order, such as 30°C.

[0073] Specifically, if the detected intercooler temperature is higher than the second preset temperature, the intercooler is faulty and cannot dissipate heat properly. Therefore, the intercooler control information is updated to reduce the engine speed and keep the coolant flow control solenoid valve open, so that the engine keeps running at low speed and low load.

[0074] S270. If the subsequent temperature of the intercooler is less than or equal to the second preset temperature, the intercooler control information is updated to close the coolant flow control battery valve.

[0075] Specifically, if the detected intercooler temperature is less than or equal to the second preset temperature, the intercooler will cool down to the normal range and there will be no fault in the intercooler. Therefore, the intercooler control information will be updated to close the coolant flow control battery valve.

[0076] S280. Continue to control the intercooler according to the updated intercooler control information.

[0077] Specifically, the intercooler is controlled based on the intercooler control information obtained from the intercooler temperature determination.

[0078] For example, when the temperature exceeds the limit, the engine controls the opening of the solenoid valve to adjust the intercooler temperature and reminds the driver. When the intercooler temperature returns to the range, the solenoid valve closes and the reminder message is canceled. If the intercooler temperature does not return to the range after 1 minute, the ECU controls the engine to run at low speed and low load and reminds the driver to check for maintenance.

[0079] In this embodiment of the invention, the presence of a fault in the intercooler is determined by judging the temperature of the intercooler. If a fault is found, the engine is kept running at low speed and low load until repair is completed. This avoids the risk of catalytic converter burnout and abnormal high temperature radiation from the catalytic converter causing vehicle spontaneous combustion or water accumulation leading to high cylinder pressure and damage to the piston connecting rod after the intercooler is damaged.

[0080] Example 3

[0081] Figure 3 This is a flowchart of a humidity fault control method for an intercooler provided in Embodiment 3 of the present invention. This embodiment is a further elaboration of the above embodiments. Figure 3 As shown, the method includes:

[0082] S310. Determine the intercooler control level based on the vehicle's current road information and driving power demand information.

[0083] S320. Determine the battery valve opening parameters based on the intercooler control level.

[0084] S330. If the intercooler humidity is greater than the first preset humidity and the ambient humidity is greater than the reference ambient humidity, then the intercooler control information is to close the drain control battery valve.

[0085] The first preset humidity can be the maximum humidity value that can be preset according to actual needs to ensure the normal operation of the intercooler, such as 80%RH, where %RH is relative humidity. The ambient humidity can be the humidity of the environment around the intercooler, such as 100%RH. The reference ambient humidity can be a reference ambient humidity set according to the actual ambient humidity when the intercooler is working; or it can be the first preset humidity.

[0086] Specifically, if the intercooler humidity is greater than or equal to the first preset humidity and the ambient humidity is greater than the reference ambient humidity, it means that the vehicle is currently in a relatively humid environment, such as during thunderstorms. In this case, it is considered that the intercooler humidity exceeds the limit due to environmental reasons, and the engine is considered to be running normally, and the drain control battery valve does not open.

[0087] S340. If the intercooler humidity is greater than the first preset humidity and the ambient humidity is less than or equal to the reference ambient humidity, then the intercooler control information is to open the drain control battery valve.

[0088] Specifically, if the intercooler humidity is greater than the first preset humidity and the current ambient humidity is lower than the reference ambient humidity, it is considered that the intercooler humidity exceeding the limit is caused by the intercooler itself and needs to be dehumidified. Therefore, the intercooler control information is updated to open the drain control battery valve.

[0089] For example, suppose the first preset humidity is 80%RH, the intercooler humidity is 90%RH, the ambient humidity is 65%RH, the reference ambient humidity is 80%RH, the intercooler humidity is greater than the first preset humidity, and the ambient humidity is 65%RH less than the reference ambient humidity of 80%RH. At this time, the intercooler humidity exceeds the limit, and the control information of the intercooler is updated to open the drain control battery valve.

[0090] The above steps determine whether the excessive humidity in the intercooler is due to increased humidity within the intercooler itself or due to environmental factors, by assessing the ambient humidity level, thus avoiding misjudgment.

[0091] S350: After opening the drain control solenoid valve according to the solenoid valve opening parameters, determine the subsequent humidity of the intercooler after a preset time period.

[0092] Specifically, the coolant flow rate is controlled by the solenoid valve opening parameters to open the solenoid valve and control the opening of the drain solenoid valve. After the drain solenoid valve opens, the intercooler is dehumidified, and the current humidity of the intercooler is measured after 1 minute. Humidity can be detected using a humidity sensor or other humidity-detecting equipment.

[0093] S360. If the subsequent humidity of the intercooler is greater than the second preset humidity, the intercooler control information is updated to reduce the engine speed and keep the drain control battery valve open; wherein, the second preset humidity is less than the first preset humidity.

[0094] The second preset humidity can be a humidity that ensures the intercooler is in normal condition, such as 20%RH.

[0095] Specifically, if the detected humidity of the intercooler is greater than the second preset humidity, the intercooler is faulty and cannot drain properly. Therefore, the intercooler control information is updated to reduce the engine speed and keep the drain control solenoid valve open, so that the engine keeps running at low speed and low load.

[0096] S370. If the subsequent humidity of the intercooler is less than or equal to the second preset humidity, the intercooler control information is updated to close the drain control battery valve.

[0097] Specifically, if the detected humidity of the intercooler is less than or equal to the second preset humidity, the humidity of the intercooler has reached the normal range, so the intercooler control information is updated to close the drain control battery valve.

[0098] S380. Continue to control the intercooler based on the updated intercooler control information.

[0099] For example, when the humidity exceeds the limit, the engine control solenoid valve performs a drainage operation for 1 minute and reminds the driver. When the intercooler humidity returns to the range, the solenoid valve closes and the reminder message is canceled. If the intercooler humidity does not return to the range after 1 minute, the ECU controls the engine to run at low speed and low load and reminds the driver to check for maintenance.

[0100] In this embodiment of the invention, the presence of a fault in the intercooler is determined by assessing its humidity. If a fault is found, the engine is kept running at low speed and low load until repair is completed. This avoids the risk of catalytic converter burnout or vehicle spontaneous combustion caused by abnormal high temperature radiation from the catalytic converter, or the risk of high cylinder pressure due to water accumulation damaging the piston and connecting rod after the intercooler is damaged.

[0101] Example 4

[0102] Figure 4 This is a flowchart of an intercooler pressure fault control method provided in Embodiment 4 of the present invention. This embodiment is a further elaboration of the above embodiments. Figure 4As shown, the method includes:

[0103] S410. Determine the intercooler control level based on the vehicle's current road information and driving power demand information.

[0104] S420. Determine the battery valve opening parameters based on the intercooler control level.

[0105] S430. If the intercooler pressure is less than the first preset pressure and the ambient pressure is less than the reference ambient pressure, then the intercooler control information is to maintain the engine speed.

[0106] The first preset pressure can be the maximum pressure at which the intercooler can operate normally, preset according to actual needs. For example, the first preset pressure can be 250 kPa, where kPa stands for kilopascals. The ambient pressure can be the pressure of the environment surrounding the intercooler, such as 200 kPa. The reference ambient pressure can be a reference ambient pressure set according to the actual ambient pressure when the intercooler is operating; it can also be the first preset pressure.

[0107] Specifically, when the intercooler pressure is lower than the first preset pressure and the ambient pressure is lower than the upper limit of the reference ambient pressure, the increase in intercooler pressure is considered to be due to the intercooler itself being pressurized, and no action is required. Therefore, the engine maintains its current speed and continues to be pressurized.

[0108] S440. If the intercooler pressure is less than the first preset pressure and the ambient pressure is greater than or equal to the reference ambient pressure, the intercooler control information is to reduce the engine speed and shut down the turbocharger.

[0109] Specifically, if the detected intercooler pressure is lower than the first preset pressure, the intercooler pressure is abnormal. Therefore, the intercooler control information is updated to reduce the engine speed and shut down the turbocharger, so that the engine runs at low speed and low load and stops increasing the intercooler pressure.

[0110] S450: Continue to control the intercooler based on the updated intercooler control information.

[0111] For example, when the pressure value exceeds the limit, the ECU controls the engine to run at low speed and low load, stops the turbocharger from working, and reminds the driver to check for maintenance.

[0112] In this embodiment of the invention, the presence of a fault in the intercooler is determined by judging the intercooler pressure. If a fault is found, the engine is kept running at low speed and low load, and the turbocharger is stopped until repair is completed. This avoids the risk of catalytic converter burnout and vehicle spontaneous combustion caused by abnormal high temperature radiation from the catalytic converter, or the risk of high cylinder pressure and piston rod damage due to water accumulation caused by water accumulation after the intercooler is damaged.

[0113] Example 5

[0114] Figure 5 A flowchart of another intercooler fault control method is provided for Embodiment 5 of the present invention, as follows: Figure 5 As shown, after the vehicle starts, the ECU determines whether the current intercooler temperature, humidity, and pressure are normal. If normal, the engine starts normally and runs normally, and the vehicle begins to move. During vehicle operation, the ECU determines the intercooler control level based on the current road information and continuously monitors the current temperature, humidity, and pressure values ​​of the intercooler, as well as the ambient temperature, pressure, and humidity values. By continuously comparing these with preset parameters, it determines whether the temperature, humidity, and pressure are abnormal during vehicle operation. If the temperature is abnormal, the ECU controls the coolant flow and opens the solenoid valve for 1 minute. If the temperature is normal after 1 minute, the determination continues. If the temperature is abnormal, the ECU checks for abnormalities and confirms the cause of the intercooler malfunction. After vehicle repair, the intercooler resumes normal operation. The same logic applies to abnormal humidity. When the pressure is abnormal, the ECU controls the turbocharger to stop working and controls the engine to run at low speed and low load. At the same time, the ECU checks for abnormalities and confirms the cause of the intercooler malfunction. After vehicle repair, the intercooler resumes normal operation. If the ECU determines that the current intercooler temperature, humidity, and pressure are abnormal, the ECU will prevent the engine from starting, check for abnormalities, confirm the cause of the intercooler malfunction, and resume normal operation after vehicle repair.

[0115] The technical solution of this embodiment collects information on intake and exhaust pressure, temperature, and humidity to determine whether the intercooler is faulty. This avoids the risk of catalytic converter burnout caused by intercooler pipe rupture, vehicle spontaneous combustion caused by abnormal high temperature radiation from the catalytic converter, and engine damage caused by intercooler filter leakage leading to water accumulation in the cylinder.

[0120] The intercooler control information determination module 530 is used to determine intercooler control information based on the comparison results of intercooler temperature and ambient temperature with preset temperatures, the comparison results of intercooler humidity and ambient humidity with preset humidity, and the comparison results of intercooler pressure and ambient pressure with preset pressure; wherein, the intercooler control information includes battery valve control information.
