[0002] The dynamic performance of an engine is closely related to the overall performance of a vehicle, and engine mount rubber pads have a significant impact on engine performance. The main function of engine mount rubber pads is to cushion and dampen vibrations, absorbing vibrations from the engine during operation and preventing them from being transmitted to the vehicle body, thus maintaining smooth engine operation. When engine mount rubber pads wear, it has adverse effects, such as increased engine vibration, increased vehicle noise, and reduced ride comfort. Furthermore, long-term wear can also cause the engine mount to loosen, affecting engine positioning accuracy, and in severe cases, affecting its normal operation and shortening its service life. Therefore, it is necessary to monitor and provide early warning of the wear condition of engine mount rubber pads. In related technologies, the wear condition of engine mount rubber pads is typically assessed through regular manual inspections. However, this method is not only time-consuming and labor-intensive, but also difficult to monitor in real time. If wear exceeds safe limits and is not detected in time, it can seriously affect vehicle performance and safety, a problem that urgently needs to be addressed. Summary of the Invention

When the current state of the engine is a preset fluctuation state, the pressure anomaly coefficient is obtained based on the current pressure detection result and the third preset threshold.
[0011] The engine mount rubber pad wear warning method proposed in this application involves controlling an acceleration sensing component, a displacement sensing component, and a pressure sensing component to detect the current state of the engine mount rubber pad based on wear monitoring commands.

A current warning level is determined based on the current wear level result, and a warning is issued and / or graded control is performed on the current vehicle according to the current warning level. Therefore, by using high-precision sensors to collect various operational data of the engine mount rubber pad in real time, the wear condition of the rubber pad can be accurately analyzed, solving the problem that existing technologies cannot monitor the wear condition of the mount rubber pad in real time. This allows for early warning to the user before the mount rubber pad wears to the point of affecting the normal operation of the vehicle, thereby improving the user's driving experience.

Detailed Implementation
[0024] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0025] The following description, with reference to the accompanying drawings, outlines a method, apparatus, vehicle, and storage medium for predicting engine mount pad wear according to embodiments of this application.
[0026] Figure 1 This is a flowchart of an engine mount rubber pad wear warning method according to an embodiment of this application.
[0027] Before introducing the engine bracket rubber pad wear warning method proposed in the embodiments of this application, let's briefly introduce the relevant technical background.
[0028] Understandably, the primary function of engine mount rubber pads is to provide effective cushioning and shock absorption. They effectively absorb various vibrations generated by the engine during operation, preventing these vibrations from being directly transmitted to the vehicle body structure, thus ensuring the engine operates in a relatively stable state. The presence of these pads not only helps extend the engine's lifespan but also significantly improves the vehicle's driving comfort and overall stability. However, when engine mount rubber pads wear down due to prolonged use, their cushioning and shock absorption effects will be greatly weakened, or even completely lost. This will cause engine vibrations to be directly transmitted to the vehicle body, leading to a series of adverse effects. Specifically: (1) Increased vibration: The engine will generate vibration when it is running. The role of the bracket rubber pad is to buffer and isolate these vibrations. When the bracket rubber pad is worn, the buffering effect will be weakened, and the vibration will be transmitted to the vehicle body more directly, resulting in obvious shaking inside the vehicle. When idling or driving at low speed, you will feel obvious vibration in the steering wheel, seat and other parts, which will affect driving comfort.
[0029] (2) Increased noise: Due to the enhanced vibration transmission, the noise generated by the engine will be more clearly transmitted into the car. At the same time, the worn bracket pads may rub or collide with other parts when the engine vibrates, generating additional noise and increasing the noise in the car.
[0030] (3) Component damage: Excessive vibration can cause bolts, nuts and other connecting parts at the connection between the engine and the vehicle body to loosen easily. It can also cause additional pulling and wear on the pipes and lines around the engine, increasing the risk of damage to other components, such as oil pipe rupture, short circuit and other faults.
[0031] (4) Increased fuel consumption: Wear of the engine mount rubber pads may cause a slight change in the engine's installation position, affecting the coaxiality of the engine's crankshaft, drive shaft and other components, which in turn affects the mechanical transmission efficiency inside the engine. In the long run, this may lead to problems such as reduced engine power and increased fuel consumption.
[0032] (5) Unstable handling: Increased engine vibration may be transmitted to the steering and suspension systems through the chassis, causing the driver to feel additional vibration and instability when operating the vehicle, which seriously affects the vehicle's handling accuracy and driving stability.
[0033] Currently, there is no corresponding early warning system, and the wear of engine mount rubber pads is usually determined by regular manual inspections. However, this method is not only time-consuming and labor-intensive, but also difficult to monitor in real time. If the wear exceeds the safe range and is not detected in time, it may seriously affect vehicle performance and safety.
[0034] Based on the aforementioned problems, this application proposes an engine mount rubber pad wear warning method. By using a high-precision sensor, various operational data of the engine mount rubber pad are collected in real time, and the wear condition of the pad is accurately analyzed, thereby detecting wear problems in advance. This solves the problem that existing technologies cannot monitor the wear condition of mount rubber pads in real time, enabling early warning to be issued to the user before the wear of the mount rubber pads affects the normal operation of the vehicle, thus improving the user's driving experience.
[0035] The following section will elaborate on the method for early warning of wear on the rubber pads of the engine mount.
[0036] like Figure 1 As shown, the engine mount rubber pad wear warning method employs an acceleration sensing component, a displacement sensing component, and a pressure sensing component. The method includes the following steps: In step S101, a wear monitoring command is obtained, and based on the wear monitoring command, the acceleration sensing component, displacement sensing component, and pressure sensing component are controlled to detect the current state of the engine bracket rubber pad and obtain the current detection result.
[0037] Specifically, the vehicle is first started to provide a clear start command (i.e., a wear monitoring command) to the wear monitoring device. Upon receiving the wear monitoring command, the device can perform a comprehensive and detailed detection of the engine mount condition using acceleration sensing, displacement sensing, and pressure sensing components to obtain the current detection result (i.e., the current detection result is obtained from the detection values of each sensor). The acceleration sensing component can be a miniature acceleration sensor, which can be mounted on the vehicle frame near the engine mount mount to capture minute vibration signals generated during vehicle operation; the displacement sensing component can be a miniature displacement sensor, which can be mounted on the metal frame of the engine mount mount to accurately measure the minute deformation of the mount when subjected to external forces; and the pressure sensing component can be a miniature pressure sensor, which can be mounted on the contact surface between the engine mount mount and the engine to monitor the pressure changes between them in real time.
[0038] Therefore, through the coordinated work of acceleration sensing components, displacement sensing components, and pressure sensing components, comprehensive data on the condition of engine mount rubber pads can be collected. This allows for a thorough assessment of the engine mount rubber pad condition, enabling timely understanding of wear and tear and ensuring the safety and stability of vehicle operation.
[0039] In step S102, based on the current detection results, the wear condition of the engine bracket rubber pads is evaluated, and the current wear level result is generated.
[0040] In other words, after obtaining the current test results of the engine mount rubber pads, a detailed assessment of the wear level of the engine mount rubber pads can be made based on the current test results, and a detailed wear level assessment result can be generated accordingly. This helps users better understand the usage status of the engine mount rubber pads and provides a scientific basis for subsequent maintenance and replacement.
[0041] To facilitate understanding, the following details how to assess the wear condition of the engine mount rubber pads based on the current test results and generate the current wear level result.
[0042] As one possible approach, in some embodiments, the wear condition of the engine mount rubber pad is assessed based on the current detection results to generate a current wear level result, including: calculating the current wear index of the engine mount rubber pad based on the current detection results; and determining the current wear level result according to the level range in which the current wear index is located.
[0043] Optionally, in some embodiments, the current wear index is:
[0044] in, The current wear index, For acceleration exceeding the limit multiple, The proportion of displacement exceeding the limit. This is the pressure anomaly coefficient. , , These are all weighting coefficients, for example, It can be 0.5. It can be 0.3. It can be 0.2.
[0045] Specifically, based on the current detection results (including current acceleration detection results, current displacement detection results, and current pressure detection results) obtained by summing the detection values of each sensing component (i.e., acceleration sensing component, displacement sensing component, and pressure sensing component), the current wear index of the engine bracket pad can be calculated using Equation (1).
[0046] After calculating the current wear index of the engine mount rubber pad by combining the current detection results of each sensor, the current wear level can be determined according to the level range in which the current wear index is located.
[0047] That is: if the current wear index If the current wear level is determined to be the preset level three wear (i.e., no wear or slight wear); if the current wear index If the current wear level is determined to be the preset level 2 wear (i.e., moderate wear); if the current wear index If so, the current wear level is determined to be the preset level 1 wear (i.e., heavy wear).
[0048] Next, we will explain in detail how to obtain the acceleration over-limit multiple, displacement over-limit ratio, and pressure anomaly coefficient.
[0049] Optionally, in some embodiments, before calculating the current wear index of the engine mount rubber pad based on the current detection result, the method further includes: determining the current acceleration detection result based on the current detection result; and obtaining the acceleration over-limit multiple based on the ratio of the current acceleration detection result to the target threshold corresponding to the current acceleration detection result.
[0050] Specifically, the acceleration exceeding the limit multiple The calculation can be shown in equation (2):
[0051] The target threshold of the acceleration sensing component is the upper limit corresponding to the current acceleration detection result (for example, if the current acceleration detection result is 10g (corresponding to the range indicating a decrease in the rubber elasticity of the engine mount pad [8g, 12g]), then the target threshold of the acceleration sensing component is 12g; if the current acceleration detection result is 14g (corresponding to the range indicating a risk of internal cracks [12g, 15g]), then the target threshold of the acceleration sensing component is 15g; if the previous acceleration detection result is 16g, exceeding the "structural failure" threshold, the target threshold of the acceleration sensing component is still 15g). Optionally, in some embodiments, before calculating the current wear index of the engine mount rubber pad based on the current detection results, the method further includes: determining the current displacement detection result based on the current detection results; when the vehicle is currently stationary, calculating a first difference between the current displacement detection result and a preset warning value, and calculating a second difference between a preset replacement value and a preset warning value, and obtaining the displacement over-limit ratio based on the ratio of the first difference to the second difference; when the vehicle is currently in operation, obtaining the displacement over-limit ratio based on the current displacement detection result and a first preset threshold.
[0052] Understandably, the current displacement detection result in a static state refers to the deformation of the engine mount rubber pad when the vehicle is stationary, reflecting the static stiffness (hardness) and creep state of the engine mount rubber pad. The current displacement detection result in a running state refers to the amplitude (generally peak-to-peak value) of the engine mount rubber pad vibrating back and forth during vehicle movement, reflecting the buffering and vibration isolation capabilities of the engine mount rubber pad under dynamic conditions.
[0053] Displacement exceeding the limit ratio The calculation can be shown in equations (3)-(4):
[0054] in, This refers to the proportion of displacement exceeding the limit when the vehicle is stationary. The current static deformation is the current displacement detection result when the vehicle is stationary. The preset warning value is 6mm, and the preset replacement value is the structural failure value of 8mm.
[0055] in, This refers to the proportion of vehicle displacement exceeding the limit while the vehicle is in operation. The current dynamic displacement peak value is the current displacement detection result when the vehicle is in operation. The first preset threshold can be 5mm.
[0056] Optionally, in some embodiments, before calculating the current wear index of the engine mount rubber pad based on the current detection results, the method further includes: determining the current pressure detection result based on the current detection results; if the current state of the engine is a preset stable state, obtaining a pressure anomaly coefficient based on the current pressure detection result and a second preset threshold; if the current state of the engine is a preset fluctuating state, obtaining a pressure anomaly coefficient based on the current pressure detection result and a third preset threshold.
[0057] It is understandable that a preset stable state refers to a situation where the engine operates under stable conditions (such as constant speed and constant load), and the pressure acting on the engine mount rubber pad is continuous and stable. The current pressure detection result under the preset stable state reflects the continuous, static force borne by the engine mount rubber pad when it deforms under a stable load. A preset fluctuating state refers to a situation where the pressure acting on the engine mount rubber pad is dynamically changing due to changes in engine operating conditions (such as rapid acceleration, rapid deceleration, load changes, etc.) during vehicle operation. The current pressure detection result under the preset fluctuating state refers to the amplitude (fluctuation rate) of the pressure change acting on the engine mount rubber pad during vibration.
[0058] Pressure Anomaly Coefficient The calculation can be shown in equations (5)-(6):
[0059] in, This refers to the pressure anomaly coefficient when the engine is in a preset stable state. This refers to the pressure anomaly coefficient of the engine under a preset fluctuation state. The current steady-state pressure is the current pressure detection result of the engine under a preset stable state. The current pressure fluctuation is the current pressure detection result of the engine under a preset fluctuation state. It is also the ratio of the difference between the instantaneous maximum pressure (P_max) and minimum pressure (P_min) collected by the pressure sensing component in real time within a complete vibration cycle of the engine to the reference value (such as the average value within the current vibration cycle). The second preset threshold can be 3.5MPa, and the third preset threshold can be 20%.
[0060] In step S103, the current warning level is determined based on the current wear level result, and a warning is issued and / or graded control is performed on the current vehicle based on the current warning level.
[0061] In other words, based on the current wear level results, the current warning level can be analyzed and determined. Based on this, corresponding warning measures are taken according to the determined current warning level, and, as needed, a graded control strategy is implemented for the vehicle to ensure the safety and reliability of vehicle operation.
[0062] Next, we will explain in detail how to determine the current warning level based on the current wear level results, and how to issue a warning and / or implement graded control on the current vehicle based on the current warning level.
[0063] As one possible implementation method, in some embodiments, the current warning level is determined based on the current wear level result, and a warning is issued and / or graded control is performed on the current vehicle based on the current warning level, including: if the current wear level result is a preset level one wear, determining the current warning level as a level one warning; generating a level one warning reminder message based on the level one warning, and triggering a preset emergency braking logic, wherein the level one warning reminder message includes the current wear index and a driving prohibition command; and controlling the current vehicle to enter an idle self-check mode and prohibiting driving based on the preset emergency braking logic and the driving prohibition command.
[0064] Specifically, combined Figure 2 As shown, if a detailed assessment determines that the engine mount rubber pads exhibit pre-set Level 1 wear (i.e., severe wear), and this wear significantly impacts normal vehicle operation, the system will automatically classify the current warning level as Level 1. Based on this, the system can generate corresponding Level 1 warning alerts according to the standards for Level 1 warnings. These alerts will be delivered to the user immediately through multiple channels, including in-vehicle smart terminals and mobile app push notifications, allowing the user to promptly detect the risk and simultaneously activate the pre-set emergency braking logic. The Level 1 warning alert includes the specific value of the current wear index and a clear prohibition on driving. Subsequently, the system will control the vehicle according to the pre-set emergency braking logic and the issued prohibition on driving command, putting it into idle self-check mode and strictly prohibiting further vehicle movement in this mode to ensure safety.
[0065] At the same time, the system can also automatically call the after-sales service center to promptly notify professional repair personnel to rush to the scene for handling, striving to resolve the fault in the shortest possible time, saving car owners valuable time as much as possible, and minimizing economic losses caused by vehicle malfunctions.
[0066] In one possible implementation, in other embodiments, the current warning level is determined based on the current wear level result, and a warning is issued and / or graded control is performed on the current vehicle based on the current warning level, including: if the current wear level result is a preset level two wear, the current warning level is determined to be a level two warning; a level two warning reminder message is generated based on the level two warning, and an alarm is triggered to issue an alarm notification, wherein the level two warning reminder message includes the current wear index, the estimated remaining safe mileage, and the recommended maintenance time.
[0067] Specifically, combined Figure 2 As shown, if a detailed assessment determines that the engine mount rubber pads exhibit a preset level 2 wear (i.e., moderate wear), the system will automatically classify the current warning level as Level 2. Based on this level 2 warning determination, the system will further generate corresponding Level 2 warning alerts and provide advance warning to the user via an alarm, such as issuing an alarm sound and turning the vehicle's display panel red. However, to ensure normal driving is not affected, the user is allowed to manually disable the alert. The alert will be triggered again after the accumulated mileage reaches L1 or the accumulated operating time reaches T1, reminding the user to perform timely maintenance. This Level 2 warning alert includes the current wear index value, the estimated remaining safe mileage based on the current wear condition, and a suggested maintenance schedule based on a comprehensive analysis of the wear level and mileage. This comprehensive information aims to help users understand the equipment's condition in a timely manner, take necessary maintenance measures, and ensure safe operation.
[0068] In some other embodiments, as one possible implementation, a current warning level is determined based on the current wear level result, and a warning is issued and / or graded control is performed on the current vehicle based on the current warning level, including: maintaining the normal operation of the current vehicle when the current wear level result is a preset level three wear, recording the current wear level result as a log, and storing the log in a preset local memory.
[0069] Specifically, if a detailed assessment determines that the engine mount rubber pads exhibit a preset level three wear (i.e., no wear or slight wear), which has not yet reached a level affecting the vehicle's normal driving performance, then it can be determined that all vehicle components are in normal working condition, and the vehicle can continue to operate normally. Furthermore, to facilitate subsequent tracking and maintenance, the current wear level can be recorded in detail, forming a complete log. In addition, this generated log information can be stored in a preset local storage device for quick and convenient retrieval and analysis when needed, thereby improving vehicle maintenance and management.
[0070] Furthermore, during each warning and processing step, the system comprehensively uploads all relevant data to cloud storage, gradually building a vast and comprehensive vehicle fault database. This database not only records various types of vehicle fault cases but also includes detailed handling processes and solutions. When users encounter similar problems again in the future, the system can quickly and accurately retrieve all relevant information from this massive database. By employing advanced intelligent algorithms, the system can simulate multiple feasible solutions for users and comprehensively consider the user's current situation, such as vehicle condition and driving environment, selecting the most reasonable and effective suggestions to provide to the user.
[0071] The engine mount rubber pad wear warning method proposed in this application involves controlling an acceleration sensing component, a displacement sensing component, and a pressure sensing component to detect the current state of the engine mount rubber pad based on wear monitoring commands. Based on the obtained current detection results, the wear condition of the engine mount rubber pad is evaluated, and a current wear level result is generated. A current warning level is determined based on the current wear level result, and a warning is issued and / or graded control is performed on the current vehicle according to the current warning level. Therefore, by using high-precision sensors to collect various operational data of the engine mount rubber pad in real time, the wear condition of the rubber pad can be accurately analyzed, solving the problem that existing technologies cannot monitor the wear condition of the mount rubber pad in real time. This allows for early warning to the user before the mount rubber pad wears to the point of affecting the normal operation of the vehicle, thereby improving the user's driving experience.
[0072] Next, referring to the accompanying drawings, we describe the engine mount rubber pad wear warning device proposed according to an embodiment of this application.
[0073] Figure 3 This is a block diagram of an engine mount rubber pad wear warning device according to an embodiment of this application.
[0074] like Figure 3 As shown, the engine mount rubber pad wear warning device 10 uses an acceleration sensing component, a displacement sensing component, and a pressure sensing component. The engine mount rubber pad wear warning device 10 includes a detection module 100, an evaluation module 200, and a processing module 300.
[0075] The detection module 100 is used to acquire wear monitoring commands and, based on the wear monitoring commands, control the acceleration sensing component, displacement sensing component and pressure sensing component to detect the current state of the engine bracket rubber pad and obtain the current detection result. The evaluation module 200 is used to evaluate the wear condition of the engine mount rubber pads based on the current inspection results and generate the current wear level result; The processing module 300 is used to determine the current warning level based on the current wear level result, and to issue a warning and / or perform graded control on the current vehicle based on the current warning level.
[0076] Optionally, in some embodiments, the evaluation module 200 includes: The calculation unit is used to calculate the current wear index of the engine mount rubber pads based on the current detection results; The determination unit is used to determine the current wear level result based on the current wear index's level range.
[0077] Optionally, in some embodiments, the current wear index is:
[0078] in, The current wear index, For acceleration exceeding the limit multiple, The proportion of displacement exceeding the limit. This is the pressure anomaly coefficient. , , All are weighting coefficients.
[0079] Optionally, in some embodiments, before calculating the current wear index of the engine mount rubber pads based on the current detection results, the calculation unit is further configured to: Based on the current detection results, determine the current acceleration detection result; The acceleration over-limit multiple is obtained by comparing the current acceleration detection result with the target threshold corresponding to the current acceleration detection result.
[0080] Optionally, in some embodiments, before calculating the current wear index of the engine mount rubber pads based on the current detection results, the calculation unit is further configured to: Based on the current detection results, determine the current displacement detection result; When the vehicle is currently stationary, calculate the first difference between the current displacement detection result and the preset warning value, and calculate the second difference between the preset replacement value and the preset warning value. The displacement over-limit ratio is obtained based on the ratio of the first difference to the second difference. When the vehicle is currently in operation, the displacement over-limit ratio is obtained based on the current displacement detection result and the first preset threshold.
[0081] Optionally, in some embodiments, before calculating the current wear index of the engine mount rubber pads based on the current detection results, the calculation unit is further configured to: Based on the current test results, determine the current pressure test result; If the engine is in a preset stable state, the pressure anomaly coefficient is obtained based on the current pressure detection result and the second preset threshold. Given that the engine is currently in a preset fluctuation state, the pressure anomaly coefficient is obtained based on the current pressure detection results and the third preset threshold.
[0082] It should be noted that the foregoing explanation of the engine mount rubber pad wear warning method embodiment also applies to the engine mount rubber pad wear warning device of this embodiment, and will not be repeated here.
[0083] The engine mount rubber pad wear warning device proposed in this application detects the current state of the engine mount rubber pad by controlling an acceleration sensing component, a displacement sensing component, and a pressure sensing component based on wear monitoring commands. Based on the current detection results, the wear condition of the engine mount rubber pad is evaluated, and a current wear level result is generated. A current warning level is determined based on the current wear level result, and a warning is issued and / or graded control is performed on the vehicle based on the current warning level. Therefore, by using high-precision sensors to collect various operational data of the engine mount rubber pad in real time, the wear condition of the rubber pad is accurately analyzed, solving the problem that existing technologies cannot monitor the wear condition of the mount rubber pad in real time. This allows for early warning to the user before the mount rubber pad wears to the point of affecting the normal operation of the vehicle, thereby improving the user's driving experience.
