Description

Technical Field

[0001] This invention relates to the field of engine control technology, and in particular to a method, apparatus, electronic device, and storage medium for detecting cooler leaks. Background Technology

[0002] Because natural gas engines have higher exhaust temperatures, they are more prone to knocking. Therefore, exhaust gas recirculation (EGR) technology is used to introduce a small portion of the combustion exhaust gas from the exhaust pipe into the intake pipe to mix with fresh natural gas, thereby reducing the engine's combustion temperature, reducing the formation of nitrogen oxides, and achieving the goal of environmental protection.

[0003] The EGR valve is a core electronically controlled component that controls the amount of exhaust gas recirculation, while the EGR cooler is the component that cools the exhaust gas. If the cooler leaks, the engine is prone to power fluctuations and surging. Small leaks will cause coolant to enter the cylinders and be burned directly. Large leaks will cause leaked coolant to enter the engine oil, leading to serious malfunctions such as cylinder scoring and bearing failure, posing safety risks to the vehicle and driver.

[0004] In the existing technology, the determination of cooler leakage is mainly based on the pressure difference and temperature change of the coolant, which makes it difficult to detect minute leaks and the sensitivity of coolant leakage detection is not high. Summary of the Invention

[0005] This invention provides a method, apparatus, electronic device, and storage medium for detecting coolant leaks, which solves the problem of low sensitivity in coolant leak detection. It can improve detection sensitivity while reducing the probability of engine damage and ensuring the safety of the driver and vehicle.

[0006] According to one aspect of the present invention, a method for detecting cooler leaks is provided, the method being executed by a cooler leak detection system, the cooler leak detection system including a coolant collector, a coolant concentration sensor, and a transmitter control unit; the inlet of the coolant collector is arranged upstream of a mixer, and the outlet of the coolant collector is arranged downstream of the mixer; the coolant concentration sensor is arranged inside the coolant collector; the method includes:

[0007] The coolant concentration in the coolant collector is obtained through a coolant concentration sensor, and the coolant concentration is sent to the engine control unit.

[0008] The engine control unit determines the first detection result of a cooler leak based on the coolant concentration.

[0009] According to another aspect of the present invention, a cooler leak detection device is provided, the device being disposed in a cooler leak detection system, the cooler leak detection system including a coolant collector, a coolant concentration sensor, and a transmitter control unit; the inlet of the coolant collector is arranged upstream of a mixer, and the outlet of the coolant collector is arranged downstream of the mixer; the coolant concentration sensor is arranged within the coolant collector; the device includes:

[0010] The coolant concentration acquisition module is used to acquire the coolant concentration in the coolant collector through the coolant concentration sensor and send the coolant concentration to the engine control unit;

[0017] The technical solution of this invention involves deploying a coolant collector and a coolant concentration sensor in the vehicle. The coolant concentration sensor acquires the coolant concentration in the coolant collector and sends this concentration to the engine control unit.

[0027] Example 1

[0028] Figure 1A This is a flowchart illustrating a cooler leak detection method according to Embodiment 1 of the present invention. This embodiment is applicable to cooler leak detection scenarios in exhaust gas recirculation systems. The method can be executed by a cooler leak detection device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1A As shown, the method includes:

[0029] S110. The coolant concentration in the coolant collector is obtained through the coolant concentration sensor, and the coolant concentration is sent to the engine control unit.

[0030] This solution can be implemented by a cooler leak detection system, which may include devices such as a coolant collector, a coolant concentration sensor, a transmitter control unit, a pressure sensor, and a temperature sensor. Figure 1B This is a schematic diagram of a sensor arrangement according to Embodiment 1 of the present invention, as shown below. Figure 1B As shown, the inlet of the coolant collector is located upstream of the mixer, for example, on the exhaust pipe after the cooler, and the outlet of the coolant collector is located downstream of the mixer, for example, on the intake manifold. A coolant concentration sensor can be installed inside the coolant collector. If coolant leaks, the coolant collector can collect the leaked coolant, and the coolant concentration sensor can detect the coolant concentration in the collector. The coolant leak detection system can send the coolant concentration data to the generator control unit. The coolant concentration sensor can detect the concentration of gases produced after one or more components of the coolant have evaporated; for example, it could be an ethylene glycol concentration sensor.

[0031] S120. The engine control unit determines the first detection result of coolant leakage based on the coolant concentration.

[0032] The transmitter control unit can determine the coolant concentration based on a preset concentration threshold to identify the first detection result of coolant leakage. This first detection result may include the degree of coolant leakage.

[0033] In a preferred embodiment, the cooler leak detection system further includes a pressure sensor and a temperature sensor; both the pressure sensor and the temperature sensor are arranged in the exhaust pipe after the cooler.

[0034] Based on the above solution, the method may optionally further include:

[0035] The exhaust gas pressure in the exhaust pipe is obtained through a pressure sensor, and the exhaust gas temperature in the exhaust pipe is obtained through a temperature sensor. The exhaust gas pressure and exhaust gas temperature are then sent to the engine control unit.

[0036] The engine control unit determines the second detection result of cooler leakage based on exhaust gas pressure and exhaust gas temperature.

[0037] Based on the first and second test results, the cooler leak test results are determined.

[0038] like Figure 1B As shown, an exhaust pipe can be installed after the cooler in the exhaust gas recirculation system. A temperature sensor and a pressure sensor can be installed in the exhaust pipe. The pressure sensor allows the cooler leak detection system to obtain the exhaust gas pressure in the exhaust pipe, and the temperature sensor allows it to obtain the exhaust gas temperature. After obtaining the exhaust gas pressure and temperature, the cooler leak detection system sends these data to the engine control unit (ECU). The ECU can then determine a second detection result for cooler leakage based on changes in exhaust gas pressure and temperature. This second detection result may include information such as whether the cooler is leaking and the extent of coolant leakage.

[0039] A cooler leak detection system can comprehensively evaluate the cooler leak situation based on a first detection result and a second detection result, thereby obtaining a reliable and accurate cooler leak detection result. For example, the cooler leak detection system can set evaluation weights for the first and second detection results, respectively, referred to as the first evaluation weight and the second evaluation weight. Based on the first detection result, the second detection result, the first evaluation weight, and the second evaluation weight, the cooler leak detection system can obtain the cooler leak detection result.

[0040] This solution, in addition to detecting coolant concentration, adds the detection of exhaust gas pressure and temperature in the exhaust pipe, which is beneficial for achieving reliable and accurate coolant leak detection and enables precise quantification of coolant leak conditions.

[0041] This technical solution involves deploying a coolant collector and a coolant concentration sensor in the vehicle. The coolant concentration sensor acquires the coolant concentration within the collector and transmits this information to the engine control unit (ECU). The ECU then uses the coolant concentration to determine the initial detection result of a coolant leak. This solution addresses the issue of low sensitivity in coolant leak detection, improving detection sensitivity while reducing the probability of engine damage and ensuring driver and vehicle safety.

[0042] Example 2

[0043] Figure 2 This is a flowchart of a cooler leakage detection method provided in Embodiment 2 of the present invention. This embodiment is a refinement based on the above embodiment. Figure 2 As shown, the method includes:

[0044] S210. The coolant concentration in the coolant collector is obtained through the coolant concentration sensor, and the coolant concentration is sent to the engine control unit.

[0045] After sending the coolant concentration information to the engine control unit, the engine control unit can proceed to steps S220-S230 and S240-S250 respectively. If the coolant concentration is 0, it indicates that there is no leak in the cooler, and the engine control unit can proceed without taking any action and continue to evaluate the coolant concentration for the next time period.

[0046] S220. If the coolant concentration is greater than 0 and the coolant concentration is less than the preset concentration threshold, the first detection result of the cooler leakage is determined to be a minor leakage.

[0047] It's easy to understand that detecting coolant concentration is simpler and more sensitive than detecting changes in gas pressure and temperature. If the coolant concentration is greater than 0, it indicates a coolant leak; if the coolant concentration is less than the concentration threshold, it indicates a minor leak that should be taken seriously.

[0048] S230. If the first detection result of the cooler leak is a minor leak, the engine control unit generates cooler leak information and sends it to the vehicle system so that the vehicle system can issue a voice and / or graphic alarm based on the cooler leak information.

[0049] If the initial detection result for a cooler leak is a minor leak, the engine control unit can generate cooler leak information based on information such as coolant concentration, detection time, and detection location, and send it to the vehicle system. The vehicle system can convey warning information to the user in the form of graphics, text, and voice, such as indicating the location of the cooler leak through images and animations, and prompting a cooler leak through a combination of text, icons, and voice.

[0050] S240. If the coolant concentration is greater than or equal to the preset concentration threshold for a series of preset number of consecutive tests, the first detection result of the cooler leakage is determined to be a severe leakage.

[0051] The engine control unit can determine the persistence of coolant leakage based on multiple comparisons of coolant concentration. If the coolant concentration exceeds or reaches the concentration threshold for a preset number of consecutive times, it indicates that coolant is continuously leaking, i.e., a serious leak.

[0052] S250. If the first detection result of the cooler leak is a severe leak, the engine control parameters are adjusted through the engine control unit; wherein, the engine control parameters include fuel injection parameters and torque limiting parameters.

[0053] If the initial detection result of a cooler leak indicates a severe leak, the engine control unit can adjust engine control parameters to ensure driving safety. Specifically, these engine control parameters may include fuel injection, torque limiting, and other parameters. Upon detecting a severe leak, the engine control unit can adjust these parameters to reduce fuel injection, implement torque limiting, or shut down the engine to ensure the safety of occupants and the vehicle.

[0054] This technical solution involves deploying a coolant collector and a coolant concentration sensor in the vehicle. The coolant concentration sensor acquires the coolant concentration within the collector and transmits this information to the engine control unit (ECU). The ECU then uses the coolant concentration to determine the initial detection result of a coolant leak. This solution addresses the issue of low sensitivity in coolant leak detection, improving detection sensitivity while reducing the probability of engine damage and ensuring driver and vehicle safety.

The coolant concentration sensor is disposed within the coolant collector. Figure 3 As shown, the device includes:

[0057] The coolant concentration acquisition module 310 is used to acquire the coolant concentration in the coolant collector through the coolant concentration sensor and send the coolant concentration to the engine control unit.

[0058] The first detection result determination module 320 is used to determine the first detection result of cooler leakage based on the coolant concentration through the engine control unit.

[0059] In one feasible solution, the first detection result determination module 320 is specifically used for:

[0060] If the coolant concentration is greater than 0 and less than the preset concentration threshold, the first detection result of the coolant leak is determined to be a minor leak.

[0061] In another feasible solution, the first detection result determination module 320 is specifically used for:

[0062] If the coolant concentration is greater than or equal to the preset concentration threshold for a series of preset number of consecutive tests, the first detection result of the cooler leak is determined to be a severe leak.

[0063] Based on the above solution, optionally, the device further includes:

[0064] The leak alarm module is used to generate cooler leak information through the engine control unit if the first detection result of the cooler leak is a minor leak, and send it to the vehicle system so that the vehicle system can issue voice and / or graphic alarms based on the cooler leak information.

[0065] In this embodiment, optionally, the device further includes:

[0066] The control parameter adjustment module is used to adjust the engine control parameters through the engine control unit if the first detection result of the cooler leakage is a severe leakage; wherein, the engine control parameters include fuel injection parameters and torque limiting parameters.
