Description

Technical Field

[0001] This invention relates to the technical field of vehicle safety monitoring, and more specifically, to a vehicle safety monitoring system and a vehicle having the same. Background Technology

[0002] As an important means of transportation for humans, the safety performance of automobiles is of paramount importance. How to quickly and efficiently monitor the safety status of automobiles is a challenging problem in the industry.

[0003] Currently, automotive fault monitoring typically involves real-time collection of operating parameters of the component under test, such as temperature, current, voltage, and remaining battery power, to determine the presence of a fault. This monitoring method requires collecting a large number of parameters, which not only increases the design complexity of the monitoring module but also means that a significant error in any one parameter can cause the fault warning to fail.

[0004] There is currently no effective solution to the above problems. Summary of the Invention

[0005] The main objective of this invention is to provide a vehicle safety monitoring system and a vehicle having the same, in order to solve the technical problems that existing vehicle fault monitoring systems are difficult to design and are prone to failure of fault warning.

[0006] To achieve the above objectives, according to one aspect of the present invention, a vehicle safety monitoring system is provided, comprising: a strain module connected to a component under test in a vehicle, the strain module generating elastic deformation under the thermal deformation of the component under test; a phase change module connected to the strain module, the strain module being used to compress the phase change module to change the internal pressure of the phase change module; and a detection module connected to both the phase change module and the vehicle control unit, the detection module being used to feed back the first phase change state inside the phase change module to the vehicle control unit.

[0007] Furthermore, the vehicle safety monitoring system also includes: a pressure sensing module, which is connected to the strain module; and a big data diagnostic module, which is connected to both the pressure sensing module and the vehicle control unit. The big data diagnostic module is used to receive the pressure signal sent by the pressure sensing module, perform diagnostic analysis on the pressure signal to generate a first warning result, and send the first warning result to the vehicle control unit.

[0008] Furthermore, the big data diagnostic module is connected to the phase change module. The big data diagnostic module is used to detect the second phase change state inside the phase change module, perform diagnostic analysis on the second phase change state to generate a second warning result, and send the second warning result to the vehicle control unit.

[0009] Furthermore, the strain module includes: a strain section made of elastic material, which is connected to the phase change module; and a strain amplifier integrated on the strain section, which is connected to both the component under test and the strain section. The strain amplifier is used to receive the thermal pressure signal from the component under test and amplify the thermal pressure signal, and to apply the amplified thermal pressure signal to the strain section.

[0010] Furthermore, the pressure amplification factor of the strain amplifier is greater than or equal to 10.

[0011] Furthermore, the phase change module contains a phase change substance, which may be water vapor, ethanol, or ethylene glycol.

[0012] Furthermore, the vehicle components to be tested include at least the body, cabin, chassis, and power battery.

[0013] Furthermore, the strain module includes: a first strain unit, a second strain unit, a third strain unit, and a fourth strain unit. The first strain unit is connected to the vehicle body, the second strain unit is connected to the cabin body, the third strain unit is connected to the chassis, and the fourth strain unit is connected to the power battery. The phase change module includes: a first phase change unit, a second phase change unit, a third phase change unit, and a fourth phase change unit. The first phase change unit is connected to the first strain unit, the second phase change unit is connected to the second strain unit, the third phase change unit is connected to the third strain unit, and the fourth phase change unit is connected to the fourth strain unit.

[0014] Furthermore, the detection module may include only one detection unit, or the detection module may include multiple detection units that correspond one-to-one with each phase transition unit.

[0015] According to another aspect of the present invention, a vehicle is provided, including a vehicle safety monitoring system, wherein the vehicle safety monitoring system is the vehicle safety monitoring system described above.

[0016] Applying the technical solution of this invention, the strain module is connected to the component under test (DUT) and the phase change module of the vehicle, respectively. The detection module is signal-connected to the phase change module. The strain module undergoes elastic deformation due to the thermal deformation of the DUT, thereby compressing the phase change module to change its internal pressure. The phase change material within the phase change module undergoes a phase change under pressure. The detection module feeds back the first phase change state of the phase change material to the vehicle control unit. The vehicle control unit compares and analyzes the received information with historical fault information and then issues a corresponding fault alarm. The real-time coordinated monitoring of the above modules, with direct contact between the strain module and the DUT, and between the strain module and the phase change module, eliminates the need for a thermal parameter to force conversion process, avoiding warning failures due to parameter errors.

However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0023] Combination Figure 1 As shown, according to a specific embodiment of this application, a vehicle safety monitoring system is provided.

[0024] Specifically, the vehicle safety monitoring system includes a strain module, a phase change module, and a detection module. The strain module is connected to the component under test (DUT) of the vehicle and undergoes elastic deformation under the thermal deformation of the DUT. The phase change module is connected to the strain module and is used to compress the phase change module to change its internal pressure. The detection module is connected to both the phase change module and the vehicle's control unit, and is used to feed back the first phase change state within the phase change module to the vehicle control unit.

[0025] It should be noted that, in Figure 1 In the diagram, dashed lines represent signal connections, and solid lines represent mechanical connections.

[0026] In the embodiments of this application, the strain module is connected to the component under test (DUT) and the phase change module of the vehicle, respectively. The detection module is signal-connected to the phase change module. The strain module undergoes elastic deformation due to the thermal deformation of the DUT, thereby compressing the phase change module to change its internal pressure. The phase change material within the phase change module undergoes a phase change under pressure. The detection module feeds back the first phase change state of the phase change material to the vehicle control unit. The vehicle control unit compares and analyzes the received information with historical fault information and then issues a corresponding fault alarm. The real-time monitoring of the above modules, with direct contact between the strain module and the DUT, and between the strain module and the phase change module, eliminates the need for a thermal parameter to force conversion process, avoiding warning failure due to parameter errors.

[0027] In one exemplary embodiment of this application, the vehicle safety monitoring system further includes a pressure sensing module and a big data diagnostic module. The pressure sensing module is connected to the strain module, and the big data diagnostic module is connected to both the pressure sensing module and the vehicle control unit. The big data diagnostic module receives pressure signals sent by the pressure sensing module, performs diagnostic analysis on the pressure signals to generate a first warning result, and sends the first warning result to the vehicle control unit.

[0028] It should be noted that the pressure sensing module can be a pressure sensor or a strain gauge, which collects the pressure signal from the strain gauge. The big data diagnostic module compares the received pressure signal with the fault signals stored in the database and generates a first warning result. That is, vehicle fault warnings have two pathways: one is through comparative analysis and warning via the big data diagnostic module, and the other is through monitoring and analysis and warning via the detection module. Warning results obtained through both pathways are sent to the vehicle control unit. If the warning results match, a warning alarm is issued; if the warning results do not match, further testing is needed to check for faults in each module, i.e., each module is equipped with a self-test device. By using these two pathways for vehicle fault warning monitoring, the accuracy of the overall monitoring system can be improved.

[0029] Furthermore, the big data diagnostic module is connected to the phase change module. The big data diagnostic module is used to detect the second phase change state inside the phase change module, perform diagnostic analysis on the second phase change state to generate a second warning result, and send the second warning result to the vehicle control unit.

[0030] It should be noted that, for example, the phase change substance within the phase change module undergoes a liquid-to-gas transformation under pressure. A gas detector monitors the real-time changes in the gas content of the phase change substance. This gas detector is connected to a big data diagnostic module, which generates a second warning result based on the gas content signal sent by the gas detector. In other words, the big data diagnostic module verifies the accuracy of the phase change state detected by the detection module, thereby improving the overall accuracy of the monitoring system. The detection module can be either a gas detector or a liquid detector.

[0031] In one exemplary embodiment of this application, the strain module includes a strain section and a strain amplifier. The strain section is made of an elastic material and is connected to a phase change module, i.e., the phase change module is compressed by the strain section. The strain amplifier is integrated on the strain section and is connected to both the component under test and the strain section. The strain amplifier is used to receive and amplify the thermal pressure signal from the component under test, and to apply the amplified thermal pressure signal to the strain section.

[0032] It should be noted that the thermal pressure signal of the component under test can be either a direct thermal deformation or a virtual pressure signal, but a direct thermal deformation better reflects the true condition of the component under test. In this embodiment, the thermal pressure signal of the component under test is taken as a direct thermal deformation as an example. The strain amplifier is equipped with a pressure multiplier, such as an elastic component. When the component under test undergoes thermal deformation, the pressure multiplier also undergoes corresponding deformation, thus multiplying the thermal deformation in the strain amplifier. The strain amplifier is in contact with the strain section, and the strain section is in contact with the phase change module, ultimately changing the state of the phase change material. The strain amplifier makes the phase change of the phase change material more obvious, thereby improving the detection accuracy of the detection module.

[0033] In this embodiment, the pressure amplification factor of the strain gauge amplifier is greater than or equal to 10. It should be noted that the pressure amplification factor is set according to the actual operating conditions.

[0034] Furthermore, the phase change module encapsulates a phase change substance, which may be water vapor, ethanol, or ethylene glycol. Water vapor, ethanol, and ethylene glycol all undergo gas-liquid conversion under pressure.

[0035] As an alternative implementation, the phase change material can also be a substance capable of solid-gas conversion or a substance capable of solid-liquid conversion.

[0036] In one exemplary embodiment of this application, the components to be tested in the vehicle include at least: the vehicle body, the passenger compartment, the chassis, and the power battery. That is, the vehicle safety monitoring system simultaneously monitors the vehicle body, passenger compartment, chassis, and power battery. For example, the vehicle body may experience thermal and mechanical deformation due to a collision, and the vehicle safety monitoring system can simultaneously monitor both types of deformation; the passenger compartment may experience thermal runaway due to a malfunction, potentially leading to a fire; the chassis may experience thermal deformation due to wear, thus affecting vehicle driving safety; and the power battery may malfunction due to thermal runaway, potentially leading to a fire.

[0037] Specifically, the strain module includes: a first strain unit, a second strain unit, a third strain unit, and a fourth strain unit. The first strain unit is connected to the vehicle body, the second strain unit is connected to the passenger compartment, the third strain unit is connected to the chassis, and the fourth strain unit is connected to the power battery. The phase change module includes: a first phase change unit, a second phase change unit, a third phase change unit, and a fourth phase change unit. The first phase change unit is connected to the first strain unit, the second phase change unit is connected to the second strain unit, the third phase change unit is connected to the third strain unit, and the fourth phase change unit is connected to the fourth strain unit.

[0038] It should be noted that each component under test corresponds to a different strain unit and phase change unit, with a one-to-one configuration. This facilitates the identification of different faults and avoids increasing the difficulty of fault identification due to the superposition of thermal deformations of various components under test. Correspondingly, the pressure sensing module also includes a first pressure sensing unit, a second pressure sensing unit, a third pressure sensing unit, and a fourth pressure sensing unit. The first pressure sensing unit is used to collect the pressure signal of the first strain unit, the second pressure sensing unit is used to collect the pressure signal of the second strain unit, the third pressure sensing unit is used to collect the pressure signal of the third strain unit, and the fourth pressure sensing unit is used to collect the pressure signal of the fourth strain unit.

[0039] Furthermore, the detection module may include only one detection unit, or the detection module may include multiple detection units that correspond one-to-one with each phase transition unit.

[0040] According to another specific embodiment of this application, a vehicle is provided, including a vehicle safety monitoring system, which is the vehicle safety monitoring system in the above embodiment.

[0041] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0042] In addition to the above, it should be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this invention.
