[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] The goals of promoting green and low-carbon technologies and products, and constructing a green and low-carbon transformation of industry, have defined methanol vehicles as green products. Influenced by factors such as the international environment and China's own energy structure, methanol-hydrogen has become an important component of national energy diversification and energy strategy. With the increasing maturity of methanol-hydrogen technology and the low-cost advantage of methanol-hydrogen fuels, methanol-hydrogen electric vehicles are gradually becoming a new growth point in the vehicle market.

[0043] Taking hydrogen-ethanol electric light trucks as an example, they currently have a high degree of satisfaction in supermarket delivery and urban cold chain transportation scenarios. According to market big data statistics and analysis, the operating mileage of hydrogen-ethanol electric light trucks is gradually increasing, which also reflects the gradual increase in the market share of hydrogen-ethanol electric light trucks.

[0044] Methanol engines are the core components that ensure the normal operation of methanol-hydrogen electric vehicles. Currently, in order to ensure the normal operation of methanol engines and to monitor the concentration of methanol and air in the cylinder, so as to provide a basis for timely adjustment of fuel injection quantity and correction of air coefficient, the gas in the cylinder is usually monitored by a zirconium dioxide heated oxygen sensor.

[0045] The inventors discovered that a typical failure of methanol engines is cylinder scoring, which is mainly caused by engine overheating, loss of cylinder sealing and lubrication. Cylinder scoring is a serious failure of methanol engines, which can prevent methanol-hydrogen electric vehicles from operating normally. In severe cases, cylinder scoring may even require cylinder boring or engine replacement, causing not only great inconvenience to users but also significant losses.

[0046] Therefore, how to implement engine fault early warning and avoid potential risks is an urgent problem to be solved.

[0047] Therefore, embodiments of this application provide an engine early warning method, such as... Figure 1 As shown, the engine warning method may include at least the following steps:

[0048] S101. Obtain the excess air coefficient within a first preset time period when the engine is running.

[0049] For alcohol-hydrogen electric vehicles, key parameters during operation include: vehicle speed, atmospheric pressure, net engine output torque, friction torque, engine speed, engine fuel flow rate, output values ​​of the upstream and downstream oxygen sensors of the three-way catalytic converter, intake air volume, engine coolant temperature, output value of the three-way catalytic converter temperature sensor, positioning status, longitude, latitude, and cumulative mileage. Through statistical analysis of the above data on cylinder scoring failures in alcohol-hydrogen electric vehicles on the market, the inventors discovered that cylinder scoring failures are always accompanied by a prolonged period of high excess air coefficient. That is, when cylinder scoring occurs, the engine is in a state of insufficient fuel injection for an extended period. Therefore, the excess air coefficient can be used as a key parameter for determining the risk of cylinder scoring failure.

[0050] The specific value of the first preset duration can be set according to actual needs, and is not specifically limited here. For example, the first preset duration can be 1 hour, then the excess air coefficient within the first preset duration refers to all excess air coefficients measured within 1 hour while the engine is running.

[0051] Specifically, obtaining the excess air coefficient of the engine during a first preset time period while it is running can be done by obtaining the excess air coefficient of the target vehicle's engine during the first preset time period while it is running, based on pre-acquired historical data for the target vehicle. For example, if the first preset time period is 2 hours and the target vehicle is vehicle A, historical data for vehicle A can be obtained first. This historical data records the core parameters of vehicle A over a relatively long period. When analyzing vehicle A, the excess air coefficient of the engine during the two hours while it is running can be obtained from the historical data, thus providing a basis for judging whether there is a risk of engine failure.

[0052] Alternatively, the excess air coefficient can be obtained while the engine is running for a first preset time period. This can also be achieved by obtaining the excess air coefficient of the target vehicle's engine in real-time during the first preset time period. For example, if the first preset time period is 2 hours and the target vehicle is vehicle A, the excess air coefficient of vehicle A can be obtained in real-time while its engine is running. Once the acquisition time reaches 2 hours, the excess air coefficient for the engine running for 2 hours is obtained. This provides a basis for real-time assessment of potential engine malfunction risks.

[0053] S102. Detect whether the frequency of the excess air coefficient exceeding the preset range within the first preset time period reaches the first preset frequency.

[0054] The preset range is used to characterize the normal range of the excess air coefficient. When the excess air coefficient exceeds the preset range, that is, when the excess air coefficient is not within the normal range, it can be considered an anomaly. Accordingly, each time an excess air coefficient is detected to exceed the preset range, it is recorded as one occurrence of the excess air coefficient exceeding the preset range.

[0055] During implementation, the preset range and the first preset frequency can be set according to actual needs.

[0056] Detecting whether the frequency of excess air coefficient exceeding the preset range within the first preset time period reaches the first preset frequency can be regarded as detecting whether the frequency of abnormal excess air coefficient within the first preset time period reaches the first preset frequency. If the frequency of excess air coefficient exceeding the preset range reaches the first preset range, it means that there are too many abnormalities in excess air coefficient within the first preset time period, and the engine has a risk of failure. Then, the subsequent step S103 can be continued. If the frequency of multiple vehicles' air coefficient exceeding the preset range does not reach the first preset range, it means that there are not too many abnormalities within the first preset time period, and the engine does not have a risk of failure.

[0057] In practical applications, the preset range can include [0.95, 1], the first preset duration can be 1 hour, and the preset frequency can be 120 times. When the frequency of the excess air coefficient exceeding [0.95, 1] ​​within 1 hour reaches 120 times, the following step S103 is executed.

[0058] Of course, the embodiments of this application are only illustrative examples of the preset range including [0.95, 1]. However, this application is not limited to this. In some other implementations, the preset range can be other ranges, as long as the excess air coefficient is within the normal value within this range.

[0059] S103, Issue the first warning information.

[0060] The first warning message is used to alert users that there is a risk of engine failure and that timely maintenance is required, thereby helping users avoid engine failure and ensuring the safe operation of the engine.

[0061] In this embodiment, the excess air coefficient is first acquired during a first preset time period while the engine is running, providing a basis for detecting any abnormalities in the engine's operating state. Then, it is detected whether the frequency of the excess air coefficient exceeding a preset range within the first preset time period reaches a first preset frequency. If the frequency of the excess air coefficient exceeding the preset range reaches the first preset frequency, it indicates that the abnormality in the excess air coefficient is caused by an abnormality in the engine's operating state, and a first warning message can be issued. In this way, abnormalities in the engine's operating state can be detected promptly and accurately using engine operating data, and timely warnings can be issued by issuing a first warning message, thereby avoiding potential risks and further engine deterioration into serious malfunctions, ensuring engine safety, and contributing to improving the safety and market competitiveness of alcohol-hydrogen electric vehicles.

[0062] In some implementations, obtaining the excess air coefficient within a first preset time period while the engine is running may specifically include: obtaining the engine speed and detecting whether the engine speed is within a preset speed range; if the engine speed is within the preset speed range, then determining that the engine is running, and obtaining the excess air coefficient within the first preset time period while the engine is running.

[0063] The preset speed range can be set according to actual needs. As long as the engine speed is within the preset speed range, the engine is in operation.

[0064] For example, the preset speed range may include [1850, 3750]. After obtaining the engine speed, it can be detected whether the engine speed is within [1850, 3750]. If the engine speed is within [1850, 3750], it means that the engine is running, that is, the vehicle equipped with the engine is in motion; if the engine speed is below [1850, 3750], it means that the engine is not running.

[0065] In some other embodiments, the above-mentioned acquisition of the excess air coefficient within a first preset time period when the engine is in operation may further include: acquiring the engine coolant temperature and detecting whether the coolant temperature is within a preset temperature range; if the engine temperature is within the preset temperature range, then determining that the engine is in operation and acquiring the excess air coefficient within the first preset time period when the engine is in operation.

[0066] In some implementations, to improve the accuracy of the early warning, the detection of whether the frequency of the excess air coefficient exceeding the preset range within the first preset time period reaches the first preset frequency may specifically include: detecting whether the number of abnormal excess air coefficient groups within the first preset time period reaches the first preset number; the excess air coefficient group is formed by dividing the excess air coefficient within the first preset time period, with each excess air coefficient within a third preset time period constituting a group; the abnormal excess air coefficient group includes: the excess air coefficient group whose frequency of continuously exceeding the preset range reaches the second preset frequency; the product of the first preset number and the second preset frequency equals the first preset frequency; if the number of abnormal excess air coefficient groups reaches the first preset number within the first preset time period, then it is determined that the frequency of the excess air coefficient exceeding the preset range reaches the first preset frequency.

[0067] The first preset quantity, the third preset duration, and the second preset frequency can all be set according to actual needs, and no specific limitations are made here.

[0068] For example, the first preset duration is 1 hour, the third preset duration is 10 seconds, the second preset frequency is 5 times, and the first preset quantity is 120. Since the excess air coefficient group includes the excess air coefficient within the third preset duration, that is, the excess air coefficient group is all the excess air coefficients detected within 10 seconds. The first preset duration is 1 hour, which includes 3600 seconds, meaning it includes 360 excess air coefficient groups. If 120 or more abnormal excess air coefficient groups are detected among the 360 ​​excess air coefficient groups, it means that the number of abnormal excess air coefficient groups within the first preset duration has reached the first preset quantity. Therefore, it is determined that the frequency of excess air coefficients exceeding the preset range has reached the first preset frequency.

[0069] By setting an excess air coefficient group, and determining that the engine has a risk of failure when the number of abnormal excess air coefficient groups reaches a first preset number, it is possible to effectively avoid the situation where the warning is wrong due to the temporary or occasional deviation of the excess air coefficient from the normal value. This effectively improves the accuracy of engine warning and lays the foundation for ensuring the normal operation of the engine.

[0070] In some implementations, such as Figure 2 As shown, the engine warning method may also include the following steps:

[0071] S201. Obtain the coolant temperature within a second preset time period while the engine is running.

[0072] The second preset duration can be the same as or different from the first preset duration. Specifically, it can be set according to actual needs, and no specific limitation is made here.

[0073] For example, if the second preset duration is 1 hour, the coolant temperature can be obtained within 1 hour while the engine is running.

[0074] S202. Detect whether the frequency of coolant temperature exceeding the preset temperature range within the second preset time period reaches the third preset frequency.

[0075] The preset temperature range is used to characterize the normal range of coolant temperature. When the coolant temperature exceeds the preset temperature range, that is, when the coolant temperature is not within the normal range, it can be considered an anomaly. Correspondingly, if no coolant temperature exceeds the preset temperature range is detected, then the frequency of the coolant temperature exceeding the preset temperature range is counted as one instance.

[0076] During implementation, both the preset temperature range and the third preset frequency can be set according to actual needs, and no specific limitations are made here. For example, the preset temperature range can be less than or equal to 110℃.

[0077] Whether the frequency of coolant temperature exceeding the preset temperature range within the second preset time period reaches the third preset frequency can be regarded as whether the frequency of abnormal coolant temperature within the second preset time period reaches the second preset frequency, thus providing a basis for detecting whether coolant temperature poses a thermal risk.

[0078] If the frequency of coolant temperature exceeding the preset temperature range within the second preset time period reaches the third preset frequency, it indicates that too many temperature anomalies have occurred within the second preset time period, and step S203 is continued; if the frequency of coolant temperature exceeding the preset temperature range within the second preset time period does not reach the third preset frequency, it indicates that too many temperature anomalies have occurred within the second preset time period, and there is no thermal risk to the engine.

[0079] S203, Issue the second early warning information.

[0080] The second warning message is used to alert users that there is a risk of thermal damage to the engine, requiring timely maintenance, thereby helping users avoid engine failure.

[0081] In some implementations, to further improve the accuracy of the early warning, when detecting whether the frequency of coolant temperature exceeding the preset temperature range within a second preset time period reaches a third preset frequency, it can be detected whether the number of abnormal coolant temperature groups within the second preset time period reaches a second preset number. A coolant temperature group is formed by dividing the coolant temperature within the second preset time period, with each fourth preset time period constituting one coolant temperature group. An abnormal coolant temperature group includes: a coolant temperature group whose frequency of continuously exceeding the preset temperature range reaches a fourth preset frequency; the product of the second preset number and the fourth preset frequency equals the third preset frequency; if the number of abnormal coolant temperature groups reaches the second preset number within the second preset time period, it is determined that the frequency of coolant temperature exceeding the preset temperature range has reached the third preset frequency.

[0082] The second preset quantity, the fourth preset duration, and the fourth preset frequency can all be set according to actual needs, and no specific limitations are made here.

[0083] Specifically, the second preset quantity can be the same as the first preset quantity, the fourth preset duration can be the same as the third preset duration, and the fourth preset frequency can be the same as the second preset frequency.

[0084] For example, the second preset duration is 1 hour, the fourth preset duration is 10 seconds, the fourth preset frequency is 5 times, and the second preset quantity is 120. Since the coolant temperature group includes the coolant temperature within the fourth preset duration, that is, the coolant temperature group is all the coolant temperatures detected within 10 seconds. The first preset duration is 1 hour, which includes 3600 seconds, that is, it includes 360 coolant temperature groups. If 120 or more abnormal coolant temperature groups are detected among the 360 ​​coolant temperature groups, it means that the number of abnormal coolant temperature groups within the second preset duration has reached the second preset quantity, and it is determined that the frequency of coolant temperature exceeding the preset temperature range has reached the third preset frequency.

[0085] By setting coolant temperature groups, and determining that there is a thermal risk to the engine when the number of abnormal coolant temperature groups reaches a second preset number, it is possible to effectively avoid warning errors caused by short-term or occasional deviations in coolant temperature from normal values. This effectively improves the accuracy of engine warnings and lays the foundation for ensuring the normal operation of the engine.

[0086] In some implementations, the first warning information may include a warning report.

[0087] Accordingly, when issuing the first warning information, the vehicle information corresponding to the engine can be obtained first; then, based on the vehicle information and the excess air coefficient within the first preset time period, a warning report can be generated and issued based on the preset sending format.

[0088] Specifically, vehicle information may include license plate number, vehicle model, and other information.

[0089] When generating a warning report based on vehicle information and the excess air coefficient for a first preset time period, a chart-style warning report can be generated. This report can display vehicle information, the excess air coefficient within the first preset time period and the abnormal excess air coefficient groups it contains, as well as the report conclusions in the form of charts, which can facilitate users to view and process the report.

[0090] Preset delivery methods can include email, pop-up windows, or SMS notifications.

[0091] Similarly, the second warning information may include a second warning report.

[0092] Correspondingly, when issuing the second warning information, a second warning report can be generated based on vehicle information and coolant temperature over a second preset time period, and the second warning report can be sent out based on a preset sending format, so as to facilitate user viewing and handling.

[0093] In some implementations, the engine warning method may further include: executing step S101 in response to a warning detection command for the engine. This allows users to issue warning detection commands according to their actual needs, improving system response speed.
