[0030] As mentioned in the background section, existing technologies struggle to identify potential fatigue fractures in automobiles. To address this issue, in a typical embodiment of this application, a monitoring device, a control method for the monitoring device, a control device, a computer-readable storage medium, a processor, and a vehicle system are provided.

[0031] According to an embodiment of this application, a monitoring device is provided for detecting the dynamic load of a vehicle.

[0032] Figure 1 This is a schematic diagram of a monitoring device according to an embodiment of this application. Figure 1 As shown, the monitoring device includes:

[0033] The first monitoring component 10 is used to connect with the suspension of the vehicle and to monitor the load borne by the suspension in the vertical direction to obtain the first dynamic load data.

[0034] The second monitoring component 20 is used to connect with the suspension of the vehicle and to monitor the load borne by the suspension in the horizontal direction to obtain second dynamic load data.

[0035] The simulation device is communicatively connected to the first monitoring component 10 and the second monitoring component 20, and is used to simulate the first dynamic load data and the second dynamic load data to obtain hidden danger information. The hidden danger information is used to determine the location where the suspension may break.

[0036] In the aforementioned monitoring device, the monitoring system monitors the load borne by the suspension in the vertical direction through a first monitoring component to obtain first dynamic load data, and monitors the load borne by the suspension in the horizontal direction through a second monitoring component to obtain second dynamic load data. This improves the simulation equipment's ability to simulate the first and second dynamic load data to obtain potential hazard information, thereby determining the location where the suspension may break. Based on the hazard information, maintenance can be carried out to prevent safety accidents caused by fatigue fracture, thus solving the problem that existing technologies struggle to determine potential hazard information of automotive fatigue fracture.

[0037] It should be noted that, as Figure 1 As shown, the monitoring device also includes a signal processing component 30, such as... Figure 2As shown, the signal processing component 30 includes a first support 31 and a signal processing device 32. The signal processing device 32 is mounted on the first support 31. The signal processing device 32 receives detection signals from the first monitoring component 10 and the second monitoring component 20, processes the detection signals to obtain first dynamic load data and second dynamic load data, with the unit being N, and records the data in the vehicle controller VCU. The simulation device can then read the recorded data from the VCU to perform simulation and obtain hidden danger information, thereby determining the location where the suspension may break.

[0038] In one embodiment of this application, the vehicle includes a gas spring connected to the suspension. The gas spring vertically supports the suspension. The first monitoring component includes a first gas pressure sensor connected to the gas spring and used to collect the gas pressure of the gas spring. Specifically, the extension direction of the gas spring is parallel to the vertical direction. By collecting the gas pressure of the gas spring, the load on the suspension in the vertical direction can be monitored. By comparing the monitored load with a first initial load, the dynamic load on the suspension in the vertical direction can be obtained. The first initial load is the load on the suspension in the horizontal direction when the vehicle starts.

[0039] In one embodiment of this application, the vehicle further includes a thrust rod connected to the suspension, the thrust rod being used to horizontally support the suspension, such as... Figure 3 As shown, the second monitoring component 20 includes a bushing 21 and a second gas pressure sensor 22. The bushing 21 is mounted on the thrust rod. The second gas pressure sensor 22 includes a receiving space that surrounds the outer periphery of the bushing 21 and is filled with gas. The second gas pressure sensor 22 is used to collect the gas pressure. Specifically, the second monitoring component 20 also includes a second support 23 located on the thrust rod. The bushing 21 is wrapped around the second support 23 and located within the receiving space of the second gas pressure sensor 22, which is filled with gas. The gas pressure can be detected by the second gas pressure sensor 22 to monitor the load on the suspension in the horizontal direction. By comparing the monitored load with a second initial load, the dynamic load on the suspension in the horizontal direction can be obtained. The second initial load is the load on the suspension in the horizontal direction when the vehicle starts.

[0040] In one embodiment of this application, such as Figure 1As shown, the aforementioned thrust rod includes a first thrust rod 01 and a second thrust rod 02. The first thrust rod 01 supports the suspension along a first direction, which is either from the front of the vehicle to the rear or from the rear to the front. The second thrust rod 02 supports the suspension along a second direction, which is located in a horizontal plane and perpendicular to the first direction. Specifically, by having the first thrust rod 01 support the suspension along the first direction and the second thrust rod 02 support the suspension along the second direction, the dynamic load of the suspension in the vehicle's forward direction and in a direction perpendicular to the forward direction can be monitored, further enabling comprehensive monitoring of the suspension's dynamic load.

[0041] This application also provides a control method for a monitoring device.

[0042] Figure 4 This is a flowchart of a control method for a monitoring device according to an embodiment of this application. Figure 4 As shown, the method includes the following steps:

[0043] Step S101: At the moment the vehicle starts, the first monitoring component is synchronously controlled to reset and the first initial load is recorded.

[0044] Step S102: At the moment the vehicle starts, the second monitoring component is synchronously controlled to reset and the second initial load is recorded.

[0045] Step S103: During the driving process of the vehicle, the first monitoring component and the second monitoring component are controlled to perform detection to obtain the first dynamic load data and the second dynamic load data.

[0046] Step S104: Control the simulation equipment to perform simulation to simulate the first dynamic load data and the second dynamic load data to obtain hidden danger information. The hidden danger information is used to determine the location where the suspension may break.

[0047] In the control method of the aforementioned monitoring device, firstly, at the moment the vehicle starts, the first monitoring component is synchronously reset to record a first initial load, and simultaneously the second monitoring component is reset to record a second initial load. Then, during the vehicle's operation, the first and second monitoring components are controlled to perform detection to obtain the first and second dynamic load data. Finally, a simulation device is controlled to perform simulation to simulate the first and second dynamic load data and obtain potential hazard information. This hazard information is used to determine the location where the suspension may fracture. This control method uses simulation to obtain hazard information and determine the location where the suspension may fracture. Based on this hazard information, maintenance can be performed to prevent safety accidents caused by fatigue fracture, thus solving the problem of existing technologies struggling to determine potential hazard information related to automotive fatigue fracture.

[0048] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0049] In one embodiment of this application, after controlling the first monitoring component and the second monitoring component to perform detection and obtain the first dynamic load data and the second dynamic load data, before simulating the valid first dynamic load data and the valid second dynamic load data to obtain hidden danger information, the method further includes: determining whether the first dynamic load data and the second dynamic load data are valid based on the first initial load and the second initial load. Specifically, since the impact of the small dynamic load on the suspension on suspension damage and fracture is negligible, determining the validity of the first dynamic load data and the second dynamic load data based on the magnitude of the first initial load and the second initial load removes invalid data whose impact on suspension damage and fracture is negligible, saving storage space and reducing the workload of the simulation equipment.

[0050] In one embodiment of this application, determining the validity of the first dynamic load data and the second dynamic load data based on the first initial load and the second initial load includes: if the first ratio and / or the second ratio is greater than or equal to a predetermined ratio, determining that both the first dynamic load data and the corresponding second dynamic load data are valid. The first ratio is the ratio of the first dynamic load data to the first initial load, and the second ratio is the ratio of the second dynamic load data to the second initial load. The first dynamic load data and the second dynamic load data correspond to each other according to the acquisition time. Specifically, if the first ratio and / or the second ratio is greater than or equal to the predetermined ratio, that is, if the first dynamic load data or the corresponding second dynamic load data has a significant impact on suspension damage and fracture, then both the first dynamic load data and the corresponding second dynamic load data are determined to be valid. In addition, those skilled in the art can select an appropriate predetermined ratio according to the actual situation to ensure the accuracy of the simulation results while reducing the simulation workload, for example, 5%.

[0051] In one embodiment of this application, after determining the validity of the first dynamic load data and the second dynamic load data based on the first initial load and the second initial load, and before simulating the first dynamic load data and the second dynamic load data to obtain potential hazard information, the method further includes: classifying the valid first dynamic load data and the valid second dynamic load data according to operating conditions, including left-turning conditions, right-turning conditions, acceleration conditions, braking conditions, and straight-line conditions. Specifically, classifying the valid first dynamic load data and the valid second dynamic load data according to operating conditions makes it easier for R&D engineers to clearly understand the driver's driving habits when reading the data, thereby formulating more targeted maintenance and repair strategies and further reducing the probability of safety accidents caused by fatigue fracture.

[0052] It should be noted that the aforementioned vehicle can be equipped with two air springs symmetrical along the vehicle's central axis. When the gas pressure detected by the first monitoring component corresponding to the two air springs differs significantly, there is a proportional relationship of axle load transfer. When the second monitoring component corresponding to the second thrust rod detects a load change in the second direction, the current operating condition is determined to be a steering condition. Based on the force in the second direction and the proportional relationship of axle load transfer between the left and right air springs, it is determined whether it is a left turn or a right turn. When there is no significant change in the contact positions, but the second monitoring component corresponding to the first thrust rod detects a significant change in the force in the first direction, the current operating condition is determined to be a braking condition or an acceleration condition. Specifically, it is determined whether it is acceleration or braking based on the force in the first direction.

[0053] This application also provides a control device for a monitoring device. It should be noted that the control device for the monitoring device in this application can be used to execute the control method for the monitoring device provided in this application. The control device for the monitoring device provided in this application is described below.

[0054] Figure 5 This is a schematic diagram of the control device of the monitoring device according to an embodiment of this application. Figure 5 As shown, the device includes:

[0055] The first control unit 100 is used to synchronously control the first monitoring component to reset and record the first initial load when the vehicle is started.

[0056] The second control unit 200 is used to synchronously control the reset of the second monitoring component and record the second initial load when the vehicle is started.

[0057] The third control unit 300 is used to control the first monitoring component and the second monitoring component to perform detection during the driving of the vehicle, and to obtain the first dynamic load data and the second dynamic load data.

[0058] The fourth control unit 400 is used to control the simulation equipment to perform simulation on the first dynamic load data and the second dynamic load data to obtain hidden danger information. The hidden danger information is used to determine the location where the suspension may break.

[0059] In the control device of the aforementioned monitoring apparatus, the first control unit synchronously controls the first monitoring component to reset and record the first initial load when the vehicle starts. Simultaneously, the second control unit synchronously controls the second monitoring component to reset and record the second initial load. During vehicle operation, the third control unit controls the first and second monitoring components to perform detection, obtaining the first dynamic load data. The fourth control unit controls a simulation device to simulate the first and second dynamic load data, obtaining potential hazard information. This hazard information is used to determine the location where the suspension may fracture. By obtaining hazard information through simulation, the control device determines the location where the suspension may fracture, enabling maintenance and repair based on this information to prevent safety accidents caused by fatigue fracture. This solves the problem of existing technologies struggling to determine potential fatigue fracture hazard information in automobiles.

[0060] In one embodiment of this application, the device further includes a determining unit. This determining unit is used to determine whether the first dynamic load data and the second dynamic load data are valid after the first monitoring component and the second monitoring component have performed detection to obtain the first dynamic load data and the second dynamic load data, and before simulating the valid first dynamic load data and the valid second dynamic load data to obtain potential hazard information. Specifically, since the dynamic load on the suspension is too small to have a negligible impact on suspension damage and fracture, determining the validity of the first dynamic load data and the second dynamic load data based on the magnitude of the first initial load and the second initial load removes invalid data whose impact on suspension damage and fracture is negligible, saving storage space and reducing the workload of the simulation equipment.

[0061] In one embodiment of this application, the determining unit includes a determining module. This module is used to determine that both the first dynamic load data and the corresponding second dynamic load data are valid when a first ratio and / or a second ratio is greater than or equal to a predetermined ratio. The first ratio is the ratio of the first dynamic load data to the first initial load, and the second ratio is the ratio of the second dynamic load data to the second initial load. The first and second dynamic load data correspond to each other according to the acquisition time. Specifically, when the first ratio and / or the second ratio is greater than or equal to the predetermined ratio, that is, when the first dynamic load data or the corresponding second dynamic load data has a significant impact on suspension failure and fracture, both the first dynamic load data and the corresponding second dynamic load data are determined to be valid. Furthermore, those skilled in the art can select an appropriate predetermined ratio based on actual conditions to ensure the accuracy of the simulation results while reducing the simulation workload; for example, 5%.

[0062] In one embodiment of this application, the device further includes a classification unit. This classification unit, after determining the validity of the first dynamic load data and the second dynamic load data based on the first initial load and the second initial load, and before simulating the first dynamic load data and the second dynamic load data to obtain potential hazard information, classifies the valid first dynamic load data and the valid second dynamic load data according to operating conditions. These operating conditions include left-turning, right-turning, acceleration, braking, and straight-line operating conditions. Specifically, classifying the valid first dynamic load data and the valid second dynamic load data according to operating conditions allows R&D engineers to clearly understand the driver's driving habits when reading the data, thereby developing more targeted maintenance and repair strategies and further reducing the probability of safety accidents caused by fatigue fracture.

[0063] It should be noted that the aforementioned vehicle can be equipped with two air springs symmetrical along the vehicle's central axis. When the gas pressure detected by the first monitoring component corresponding to the two air springs differs significantly, there is a proportional relationship of axle load transfer. When the second monitoring component corresponding to the second thrust rod detects a load change in the second direction, the current operating condition is determined to be a steering condition. Based on the force in the second direction and the proportional relationship of axle load transfer between the left and right air springs, it is determined whether it is a left turn or a right turn. When there is no significant change in the contact positions, but the second monitoring component corresponding to the first thrust rod detects a significant change in the force in the first direction, the current operating condition is determined to be a braking condition or an acceleration condition. Specifically, it is determined whether it is acceleration or braking based on the force in the first direction.

[0064] This application also provides a vehicle system, including a vehicle and a control device, wherein the vehicle includes the aforementioned monitoring device, and the control device is used to execute the aforementioned control method.

[0065] The aforementioned vehicle system includes a control device comprising the vehicle and a monitoring unit. Upon vehicle startup, the first control unit synchronously controls the first monitoring component to reset and records a first initial load. Simultaneously, the second control unit synchronously controls the second monitoring component to reset and records a second initial load. During vehicle operation, the third control unit controls the first and second monitoring components to perform detection, obtaining first and second dynamic load data. The fourth control unit controls a simulation device to simulate the first and second dynamic load data, obtaining potential hazard information. This hazard information is used to determine the location where the suspension may fracture. By obtaining hazard information through simulation, the aforementioned vehicle system can determine the location where the suspension may fracture, and thus perform maintenance based on this information, preventing safety accidents caused by fatigue fracture. This solves the problem of existing technologies struggling to determine potential fatigue fracture hazard information in automobiles.

[0066] The control unit of the aforementioned monitoring device includes a processor and a memory. The first control unit, the second control unit, the third control unit, and the fourth control unit are all stored as program units in the memory. The processor executes the program units stored in the memory to achieve the corresponding functions.

[0067] The processor contains a kernel, which retrieves the corresponding program units from memory. One or more kernels can be configured, and adjusting kernel parameters can address the problem of determining potential fatigue fracture risks in automobiles, a problem that is difficult to solve with current technologies.
