[0003] In the case of wheel deformation or cracking, the deformation or cracking often starts from the inner wheel edge, that is, the rim often deforms or cracks first. Since the rim is inside the wheel, it is difficult for users to detect the deformation or cracking of the rim, which poses a great safety hazard during vehicle driving. Summary of the invention

[0007] Determining whether the vertical wheel center acceleration exceeds a target acceleration range; the target acceleration range is pre-calibrated and used to detect whether the wheel rim has deformation or cracking problems;
[0008] If the vertical wheel center acceleration of a target wheel exceeds the target acceleration range, a vehicle inspection prompt message is issued; the vehicle inspection prompt message is used to prompt the user to check whether the target wheel has rim deformation or cracking problems.
[0009] In the disclosed embodiment, the vertical wheel center acceleration of each wheel of the vehicle in the height direction can be obtained during vehicle driving. By comparing each vertical wheel center acceleration with a pre-calibrated target acceleration range, when the vertical wheel center acceleration of the target wheel exceeds the target acceleration range, it can be determined that the wheel rim is at risk of deformation or cracking, thereby issuing a vehicle inspection prompt message so that the user can check the target wheel in time. In this way, the prompt allows the user to promptly check the safety hazards of the wheel rim, avoiding the situation where the deformation or cracking of the wheel rim is difficult to find, reducing safety hazards during vehicle driving, and improving the safety of users' driving.
[0010] In an optional implementation manner, before determining whether the vertical wheel center acceleration exceeds the target acceleration range, the method further includes:
[0011] The target acceleration range matching the vehicle is determined according to the vehicle attribute information of the vehicle; wherein acceleration ranges matching different vehicle attribute information are pre-calibrated.
[0012] In the disclosed embodiment, the target acceleration matching the vehicle can be determined from a plurality of pre-calibrated acceleration ranges through the vehicle attribute information, which helps to ensure the accuracy of vehicle safety detection.
[0013] In an optional implementation manner, the acceleration range is calibrated by the following steps:
[0014] For different vehicle attribute information, corresponding test road surface attribute information is configured respectively; the test road surface attribute information indicates the height information of the test road step and the depth information of the test road pit;

[0016] The first wheel center acceleration is used as an upper threshold of the acceleration range, and the second wheel center acceleration is used as a lower threshold of the acceleration range.
[0017] In the disclosed embodiment, corresponding test road steps and test road potholes can be configured according to different vehicle attribute information, so as to obtain the corresponding first wheel center acceleration and second wheel center acceleration as the upper threshold and lower threshold of the acceleration range, respectively, to obtain the acceleration range matching the different vehicle attribute information, which helps to ensure the adaptability and effectiveness of the determined acceleration range.
[0018] In an optional embodiment, the height of the test road step is less than or equal to a target value; the target value is the difference between the tire section height indicated by the vehicle attribute information and a preset height; the tire section height refers to the vertical distance from the bottom of the tire bead to the highest point of the tread.
[0019] In the disclosed embodiment, by setting the height of the test step and the relationship between the tire section height and the preset height, it is helpful to configure a suitable test step according to the vehicle attribute information, thereby effectively improving the accuracy of vehicle safety detection.
[0020] In an optional implementation, the height of the test road step is between 80 mm and 130 mm, and the depth of the test road pit is between 40 mm and 60 mm.
[0021] In the disclosed embodiment, the height information of the test road step and the depth information of the test road pothole can be configured according to the disclosed embodiment, which helps to obtain a better acceleration range, thereby helping to improve the timeliness of vehicle safety detection.

[0024] The minimum value of the wheel center accelerations corresponding to the first preset number of wheels is used as the first wheel center acceleration, and the minimum value of the wheel center accelerations corresponding to the second preset number of wheels is used as the second wheel center acceleration.
[0025] In the disclosed embodiment, when obtaining the first wheel center acceleration and the second wheel center acceleration, it is only necessary to respectively set the first preset number of wheels and the second preset number of wheels to pass through the test road steps and the test road potholes at preset speeds, which helps to improve the efficiency of the calibration acceleration range and reduce resource consumption.
[0026] In an optional implementation, the first preset number of wheels are four wheels of the vehicle, and the second preset number of wheels are two wheels on one side of the vehicle.
[0027] In the disclosed embodiment, by setting the wheels of the test vehicle when passing through the test road steps and the test road potholes respectively in the above manner, the successful driving of the test vehicle can be ensured while obtaining a suitable acceleration range.

[0035] In the disclosed embodiment, vehicle inspection prompt information can be displayed on the vehicle screen. After the inspection completion operation is triggered by the user, the display of the vehicle inspection prompt information is cancelled. When the inspection completion operation is not triggered by the user and the excess value of the vertical wheel center acceleration exceeds the target acceleration range, the vehicle inspection prompt information is enhanced and displayed, thereby prompting the user to promptly check the safety hazards existing in the wheel rim, reduce safety hazards during vehicle driving, and improve the safety of users' driving.
[0036] The present disclosure also provides a vehicle safety detection method, the method comprising:

[0038] Determining whether the vertical wheel center acceleration exceeds a pre-calibrated target acceleration range; the target acceleration range is obtained by conducting a driving test on a test vehicle having target vehicle attribute information using a test road step having a target height and a test road pit having a target depth, and is used to detect whether the wheel rim has a deformation or cracking problem;
[0039] If the vertical wheel center acceleration of a target wheel exceeds the target acceleration range, a vehicle inspection prompt message is issued; the vehicle inspection prompt message is used to prompt the user to check whether the target wheel has rim deformation or cracking problems.
[0040] In the disclosed embodiment, the vertical wheel center acceleration of each wheel of the vehicle in the height direction can be obtained during the driving of the vehicle. By comparing each vertical wheel center acceleration with a pre-calibrated target acceleration range, when the vertical wheel center acceleration of the target wheel exceeds the target acceleration range, it can be determined that the wheel rim has a risk of deformation or cracking, so that a vehicle inspection prompt message is issued so that the user can check the target wheel in time, avoiding the situation where the deformation or cracking of the wheel rim is difficult to find, reducing safety hazards during vehicle driving, and improving the driving safety of users.

[0060] Research has found that the deformation and cracking of wheels often start from the inner wheel edge, that is, the wheel rim is often deformed or cracked first. The rim is the component that supports the tire on the inner contour of the tire. Since the rim is inside the wheel, it is difficult for users to find the deformation or cracking of the rim. Unless the entire wheel is removed and the vehicle is lifted, it is difficult for users to find the problem of wheel cracking. The deformation or cracking of the rim poses a great safety hazard to the vehicle driving process.
[0061] Based on the above research, the present disclosure provides a vehicle safety detection method, which compares the vertical wheel center acceleration of each wheel of the vehicle with a pre-calibrated target acceleration range, and issues a vehicle inspection prompt message when the vertical wheel center acceleration of the target wheel exceeds the target acceleration range, so that the user can promptly check the safety hazards existing in the wheel rim, avoid the situation where the deformation or cracking of the wheel rim is difficult to find, reduce the safety hazards during vehicle driving, and improve the safety of users' driving.
[0062] To facilitate understanding of the present embodiment, a vehicle safety detection method disclosed in the embodiment of the present disclosure is first introduced in detail. The execution subject of the vehicle safety detection method provided in the embodiment of the present disclosure is generally an electronic device with a certain computing power, and the electronic device can be a server or a terminal device or other processing device. If it is a server, the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud storage, big data and artificial intelligence platforms. If it is a terminal device, the terminal device can be a user equipment (User Equipment, UE), a mobile device, a terminal, a computing device, and a vehicle-mounted device. If it is other processing equipment, the other processing equipment can be a device including a processor and a memory, which is not limited here. In some possible implementations, the vehicle safety detection method can be implemented by a processor calling a computer-readable instruction stored in a memory.
[0063] A vehicle safety detection method provided by an embodiment of the present disclosure is described below in conjunction with the accompanying drawings.
[0064] See also Figure 1 As shown, it is a flow chart of a vehicle safety detection method provided by an embodiment of the present disclosure, such as Figure 1 As shown in , the vehicle safety detection method provided by the embodiment of the present disclosure includes steps S101 to S103, wherein:
[0065] S101: During vehicle driving, a vertical wheel center acceleration of each wheel of the vehicle is obtained, where the vertical wheel center acceleration is the acceleration of the wheel of the vehicle in a height direction.
[0066] In this step, considering that the wheel rim is more sensitive to load in the height direction than in other directions, the embodiment of the present disclosure mainly obtains the acceleration of each wheel of the vehicle in the height direction, and detects it through the vertical wheel center acceleration of the wheel, which helps to detect the risk of deformation or cracking of the rim more timely and effectively.
[0067] In some possible implementations, obtaining the vertical wheel center acceleration of each wheel of the vehicle includes:
[0068] Acquiring displacement data in a height direction collected by a height sensor of each wheel of the vehicle;
[0069] The displacement data is differentiated to obtain the vertical wheel center acceleration of the wheel.
[0070] In practical applications, the vehicle itself is usually equipped with at least one height sensor, which is mainly used to detect changes in the height of the vehicle to ensure the stability and safety of the vehicle.
[0071] Here, the displacement data in the height direction collected by the height sensor of each wheel is obtained, and the vertical wheel center acceleration of the corresponding wheel can be obtained by performing differential processing on the displacement data.
[0072] Specifically, the calculation formula of the vertical wheel center acceleration of the wheel is shown in the following formula (1):
[0073]
[0074] Wherein, a represents the vertical wheel center acceleration of the wheel, and x represents the displacement data in the height direction.
[0075] In this way, the technical solution of the present invention can be implemented by utilizing the existing sensors of the vehicle without configuring other components. The vertical wheel center acceleration of each wheel of the vehicle can be obtained conveniently and quickly, thereby improving the efficiency of vehicle safety detection.
[0076] S102: Determine whether the vertical wheel center acceleration exceeds a target acceleration range; the target acceleration range is pre-calibrated and used to detect whether the wheel rim has deformation or cracking problems.
[0077] In this step, the pre-calibrated target acceleration range may be obtained, and by comparing the vertical wheel center acceleration of each wheel with the target acceleration range, it is determined whether the vertical wheel center acceleration exceeds the target acceleration range.
[0078] Among them, the target acceleration range is used to indicate the vertical wheel center acceleration range when the wheel rim is in a normal state. It can be understood that if the vertical wheel center acceleration is within the target acceleration range, it can be determined that there is basically no possibility of deformation or cracking of the wheel rim. If the vertical wheel center acceleration exceeds the target acceleration range, it can be determined that there is a high possibility of deformation or cracking of the wheel rim.
[0079] In some possible implementations, before determining whether the vertical wheel center acceleration exceeds a target acceleration range, the method further includes:
[0080] The target acceleration range matching the vehicle is determined according to the vehicle attribute information of the vehicle; wherein acceleration ranges matching different vehicle attribute information are pre-calibrated.
[0081] Here, multiple acceleration ranges are pre-calibrated, and each acceleration range corresponds to different vehicle attribute information. In this step, the vehicle attribute information of the vehicle is compared with the vehicle attribute information corresponding to the multiple acceleration ranges, and the acceleration range whose corresponding vehicle attribute information is consistent with the vehicle attribute information of the vehicle is determined from the multiple acceleration ranges, and the determined acceleration range is used as the target acceleration range.
[0082] The vehicle attribute information includes but is not limited to the vehicle model, wheelbase, etc.
[0083] In this way, through the vehicle attribute information of the vehicle, a target acceleration matching the vehicle can be determined from multiple pre-calibrated acceleration ranges, which helps to ensure the accuracy of vehicle safety detection.
[0084] In some possible implementations, the acceleration range is calibrated by the following steps:
[0085] For different vehicle attribute information, corresponding test road surface attribute information is configured respectively; the test road surface attribute information indicates the height information of the test road step and the depth information of the test road pit;
[0086] For a test vehicle matching any of the vehicle attribute information, obtaining a first wheel center acceleration when the wheels of the test vehicle pass through the test road step at a preset speed, and a second wheel center acceleration when the wheels of the test vehicle pass through the test road pothole;
[0087] The first wheel center acceleration is used as an upper threshold of the acceleration range, and the second wheel center acceleration is used as a lower threshold of the acceleration range.
[0088] In the above steps, corresponding test steps and test potholes are configured for different vehicle attribute information, and then a test vehicle matching the vehicle attribute information passes through the test steps and the test potholes at a preset speed to obtain the first wheel center acceleration of the wheels of the test vehicle when passing through the test steps and the second wheel center acceleration when passing through the test potholes.
[0089] The first wheel center acceleration and the second wheel center acceleration are accelerations of the wheels of the test vehicle in a height direction.
[0090] It can be understood that the first wheel center acceleration is the maximum acceleration of the wheel in the height direction when the wheel rim is in a normal state, and the second wheel center acceleration is the minimum acceleration of the wheel in the height direction when the wheel rim is in a normal state, so that the first wheel center acceleration can be used as the upper limit threshold of the acceleration range, and the second wheel center acceleration can be used as the lower limit threshold of the acceleration range to constitute the acceleration range.
[0091] The specific value of the preset speed may be determined according to the actual acceleration range calibration requirements and is not limited here.
[0092] It should be noted that the test vehicle and the vehicle driven by the user performing the safety inspection are not the same vehicle. It can be understood that in order to ensure the comprehensiveness and completeness of the acceleration range calibration, test vehicles matching the attribute information of each vehicle can be prepared in advance.
[0093] In this way, corresponding test road steps and test road potholes can be configured according to different vehicle attribute information, so as to obtain the corresponding first wheel center acceleration and second wheel center acceleration as the upper threshold and lower threshold of the acceleration range respectively, so as to obtain the acceleration range matching different vehicle attribute information, which helps to ensure the adaptability and effectiveness of determining the acceleration range.
[0094] In some possible implementations, the height of the test road step is less than or equal to a target value; the target value is the difference between the tire section height indicated by the vehicle attribute information and a preset height; the tire section height refers to the vertical distance from the bottom of the tire bead to the highest point of the tread.
[0095] Here, in order to ensure the vehicle safety detection effect while ensuring that the test vehicle can successfully drive through the test step, the height of the test step is less than the tire section height. Specifically, the height of the test step is at least lower than the tire section height by the preset height.
[0096] The specific value of the preset speed may be determined according to the actual acceleration range calibration requirements and is not limited here.
[0097] Exemplarily, the preset height may be greater than 5 mm, with about 5 mm being optimal.
[0098] In this way, by setting the height of the test step and the relationship between the tire section height and the preset height, it is helpful to configure a suitable test step according to the vehicle attribute information, thereby effectively improving the accuracy of vehicle safety detection.
[0099] Under the condition that the height of the test road step is less than or equal to the target value, in order to improve the effect of vehicle safety detection, in some possible implementations, the height of the test road step is between 80 mm and 130 mm, and the depth of the test road pit is between 40 mm and 60 mm.
[0100] Exemplarily, taking different models as an example, for a Sport Utility Vehicle (SUV), the height of the test road step can be set to 120 mm, and for a crossover SUV, the height of the test road step can be set to 110 mm.
[0101] In another example, taking different wheelbases as an example, for a test vehicle with a wheelbase less than 2900 mm, the height of the test step can be set to 90 mm, and for a test vehicle with a wheelbase greater than or equal to 2900 mm, the height of the test step can be set to 100 mm.
[0102] In another example, according to different vehicle attribute information, the depth of the test road pit can be set to 50 mm or other values.
[0103] In this way, the height information of the test road step and the depth information of the test road pit can be configured according to the embodiment of the present disclosure, which helps to obtain a better acceleration range, thereby helping to improve the timeliness of vehicle safety detection.
[0104] In some possible implementations, obtaining a first wheel center acceleration when a wheel of the test vehicle passes through the test road step at a preset speed, and a second wheel center acceleration when a wheel of the test vehicle passes through the test road pothole, includes:
[0105] Obtaining the wheel center accelerations of a first preset number of wheels of the test vehicle when they pass through the test road step at a preset speed, and the wheel center accelerations of a second preset number of wheels when they pass through the test road pothole at a preset speed;
[0106] The minimum value of the wheel center accelerations corresponding to the first preset number of wheels is used as the first wheel center acceleration, and the minimum value of the wheel center accelerations corresponding to the second preset number of wheels is used as the second wheel center acceleration.
[0107] In actual applications, the test vehicle generally has four wheels. When obtaining the first wheel center acceleration and the second wheel center acceleration, the wheel center accelerations of a first preset number of wheels of the test vehicle when passing through the test road step at a preset speed and the wheel center accelerations of a second preset number of wheels when passing through the test road pothole at a preset speed can be obtained respectively.
[0108] Here, in order to ensure that whether the wheel rim is deformed or cracked can be detected in time, the minimum value of the wheel center accelerations corresponding to the first preset number of wheels can be used as the first wheel center acceleration, and the minimum value of the wheel center accelerations corresponding to the second preset number of wheels can be used as the second wheel center acceleration, so that the abnormality of the vertical wheel center acceleration of each wheel of the vehicle can be detected in time.
[0109] The method for determining the wheel center acceleration corresponding to each wheel of the test vehicle is similar to the method for determining the vertical wheel center acceleration. Specifically, the displacement data in the height direction collected by the height sensor of each wheel of the test vehicle is obtained, and the displacement data is differentiated to obtain the wheel center acceleration corresponding to the wheel of the test vehicle.
[0110] In this way, when obtaining the first wheel center acceleration and the second wheel center acceleration, it is only necessary to set the first preset number of wheels and the second preset number of wheels to pass through the test road steps and the test road potholes at the preset speeds, which helps to improve the efficiency of the calibration acceleration range and reduce resource consumption.
[0111] In some possible implementations, the first preset number of wheels are four wheels of the vehicle, and the second preset number of wheels are two wheels on one side of the vehicle.
[0112] Here, in order to obtain the acceleration range, all four wheels of the test vehicle may be set to pass through the test road step, and two wheels on one side of the test vehicle may be set to pass through the test road pit. It is understandable that if the wheels on both sides of the test vehicle enter the test road pit, it is difficult for the test vehicle to get out of the test road pit. Therefore, in order to ensure that the test vehicle can successfully drive through the test road pit, the two wheels on the left or right side of the test vehicle are set to pass through the test road pit.
[0113] In this way, by setting the wheels of the test vehicle when passing through the test road steps and the test road potholes respectively in the above manner, the successful driving of the test vehicle can be guaranteed while obtaining a suitable acceleration range.
[0114] S103: If the vertical wheel center acceleration of a target wheel exceeds the target acceleration range, a vehicle inspection prompt message is issued; the vehicle inspection prompt message is used to prompt the user to check whether the target wheel has a rim deformation or cracking problem.
[0115] In this step, when the vertical wheel center acceleration exceeds the target acceleration range, it can be determined that the wheel rim is more likely to be deformed or cracked. Therefore, if the vertical wheel center acceleration of any wheel of the vehicle exceeds the target acceleration range, the wheel is determined as a target wheel that needs to have its rim inspected, and a vehicle inspection prompt message is issued.
[0116] In some possible implementations, the issuing of vehicle inspection prompt information includes:
[0117] Displaying the vehicle inspection prompt information on the vehicle screen, wherein the vehicle inspection prompt information includes prompt information for checking whether there are any problems with the vehicle chassis and whether there are any deformation or cracking problems with the target wheel rim;
[0118] In response to the user triggering the inspection completion operation, the vehicle inspection prompt information is canceled from being displayed; otherwise, the vehicle inspection prompt information is continuously displayed, and when the excess value of the vertical wheel center acceleration exceeds the target acceleration range, the vehicle inspection prompt information is displayed in an enhanced manner.
[0119] In the above steps, the vehicle inspection prompt information can be displayed on the vehicle screen to prompt the user to check whether there are any problems with the vehicle chassis and to detect whether the target wheel rim has any deformation or cracking problems. After the user checks and confirms that there are no problems, the inspection completion operation can be triggered. When the inspection completion operation is detected, the vehicle inspection prompt information can be cancelled.
[0120] Among them, the triggering inspection completion operation includes but is not limited to receiving a user's closing trigger for the vehicle inspection prompt information in the vehicle-mounted screen, receiving the user's voice data indicating that the inspection is completed, etc.
[0121] If the inspection completion operation is not detected, the vehicle inspection prompt information is continuously displayed. In actual applications, as the degree of deformation or cracking of the rim increases, the vertical wheel center acceleration tends to increase. In order to ensure vehicle driving safety, when the vertical wheel center acceleration exceeds the target acceleration range by an increasing value, the vehicle inspection prompt information is displayed in an enhanced manner.
[0122] Among them, the enhanced display of the vehicle inspection prompt information includes but is not limited to bolding, enlarging, changing color, changing display effects, etc.
[0123] In this way, the vehicle inspection prompt information can be displayed on the vehicle screen. After the user triggers the inspection completion operation, the vehicle inspection prompt information is cancelled. When the user triggers the inspection completion operation and the vertical wheel center acceleration exceeds the target acceleration range by an increasing value, the vehicle inspection prompt information is displayed in an enhanced manner, thereby prompting the user to promptly check the safety hazards existing in the wheel rim, reduce safety hazards during vehicle driving, and improve the safety of users' driving.
[0124] In order to clearly demonstrate the process of vehicle safety inspection, you can also refer to Figure 2 , Figure 2 A schematic diagram of a vehicle safety detection process provided by an embodiment of the present disclosure. Figure 2 As shown in , corresponding test road surface attribute information is configured in advance for different vehicle attribute information, so that acceleration ranges matching different vehicle attribute information are pre-calibrated. During vehicle driving, the vertical wheel center acceleration of each wheel of the vehicle is obtained, and the target acceleration range matching the vehicle is determined according to the vehicle attribute information of the vehicle. It is judged whether the vertical wheel center acceleration exceeds the target acceleration range. If the vertical wheel center acceleration of the target wheel exceeds the target acceleration range, a vehicle inspection prompt message is displayed on the vehicle screen. In response to the user triggering the inspection completion operation, the display of the vehicle inspection prompt message is canceled. Otherwise, the vehicle inspection prompt message is continuously displayed, and when the excess value of the vertical wheel center acceleration exceeding the target acceleration range increases, the vehicle inspection prompt message is enhanced. Among them, the description of the specific steps refers to the aforementioned various embodiments, which will not be repeated here.
[0125] The vehicle safety detection method provided by the embodiment of the present disclosure can obtain the vertical wheel center acceleration of each wheel of the vehicle in the height direction during vehicle driving, and by comparing each vertical wheel center acceleration with a pre-calibrated target acceleration range, when the vertical wheel center acceleration of the target wheel exceeds the target acceleration range, it can be determined that the wheel rim is at risk of deformation or cracking, thereby issuing a vehicle inspection prompt message so that the user can check the target wheel in time. In this way, the prompt can enable the user to promptly check the safety hazards of the wheel rim, avoid the situation where the deformation or cracking of the wheel rim is difficult to find, reduce the safety hazards during vehicle driving, and improve the safety of users' driving.
[0126] See also Figure 3 As shown, it is a flow chart of another vehicle safety detection method provided by an embodiment of the present disclosure, such as Figure 3 As shown in , the vehicle safety detection method provided by the embodiment of the present disclosure includes steps S301 to S303, wherein:
[0127] S301: During vehicle driving, vertical wheel center acceleration of each wheel of the vehicle is obtained, where the vertical wheel center acceleration is the acceleration of the wheel of the vehicle in the height direction; the vehicle has target vehicle attribute information.
[0128] In this step, considering that the wheel rim is more sensitive to load in the height direction than in other directions, the embodiment of the present disclosure mainly obtains the acceleration of each wheel of the vehicle in the height direction, and detects it through the vertical wheel center acceleration of the wheel, which helps to detect the risk of deformation or cracking of the rim more timely and effectively.
[0129] Here, the vehicle attribute information possessed by the vehicle is determined as the target vehicle attribute information.
[0130] The vehicle attribute information includes but is not limited to the vehicle model, wheelbase, etc.
[0131] S302: Determine whether the vertical wheel center acceleration exceeds a pre-calibrated target acceleration range; the target acceleration range is obtained by conducting a driving test on a test vehicle with target vehicle attribute information using a test road step with a target height and a test road pothole with a target depth, and is used to detect whether the wheel rim has deformation or cracking problems.
[0132] In this step, test steps with target heights and test potholes with target depths can be used in advance to conduct driving tests on test vehicles with target vehicle attribute information to obtain a target acceleration range. When safety inspections of the vehicle are required, the pre-calibrated target acceleration range can be obtained.
[0133] Here, the target acceleration range is used to indicate the vertical wheel center acceleration range when the wheel rim is in a normal state. It can be understood that if the vertical wheel center acceleration is within the target acceleration range, it can be determined that there is basically no possibility of deformation or cracking of the wheel rim. If the vertical wheel center acceleration exceeds the target acceleration range, it can be determined that there is a high possibility of deformation or cracking of the wheel rim.
[0134] Wherein, corresponding test road surface attribute information is configured for different vehicle attribute information respectively; the test road surface attribute information indicates the height information of the test road step and the depth information of the test road pit.
[0135] Correspondingly, for the target vehicle attribute information, the height of the corresponding test road step is configured as the target height, and the depth of the corresponding test road pit is configured as the target depth, so as to perform a driving test on the test vehicle with the target vehicle attribute information to obtain the target acceleration range.
[0136] Specifically, the first wheel center acceleration of the wheels of the test vehicle with target vehicle attribute information when passing through a test road step with a target height at a preset speed and the second wheel center acceleration when passing through a test road pothole with a target depth can be obtained, and the first wheel center acceleration is used as the upper limit threshold of the target acceleration range, and the second wheel center acceleration is used as the lower limit threshold of the target acceleration range.
[0137] The first wheel center acceleration and the second wheel center acceleration are accelerations of wheels of a test vehicle having target vehicle attribute information in a height direction.
[0138] It can be understood that the first wheel center acceleration is the maximum acceleration of the wheel in the height direction when the wheel rim is in a normal state, and the second wheel center acceleration is the minimum acceleration of the wheel in the height direction when the wheel rim is in a normal state, so that the first wheel center acceleration can be used as the upper limit threshold of the target acceleration range, and the second wheel center acceleration can be used as the lower limit threshold of the target acceleration range to constitute the target acceleration range.
[0139] The specific value of the preset speed may be determined according to the actual acceleration range calibration requirements and is not limited here.
[0140] It should be noted that the test vehicle and the vehicle driven by the user performing the safety inspection are not the same vehicle. It can be understood that in order to ensure the comprehensiveness and completeness of the target acceleration range calibration, a test vehicle consistent with the vehicle attribute information of the vehicle can be prepared in advance.
[0141] S303: If the vertical wheel center acceleration of a target wheel exceeds the target acceleration range, a vehicle inspection prompt message is issued; the vehicle inspection prompt message is used to prompt the user to check whether the target wheel has a rim deformation or cracking problem.
[0142] In this step, when the vertical wheel center acceleration exceeds the target acceleration range, it can be determined that the wheel rim is more likely to be deformed or cracked. Therefore, if the vertical wheel center acceleration of any wheel of the vehicle exceeds the target acceleration range, the wheel is determined as a target wheel that needs to have its rim inspected, and a vehicle inspection prompt message is issued.
[0143] The vehicle safety detection method provided by the embodiment of the present disclosure can obtain the vertical wheel center acceleration of each wheel of the vehicle in the height direction during the driving of the vehicle. By comparing each vertical wheel center acceleration with a pre-calibrated target acceleration range, when the vertical wheel center acceleration of the target wheel exceeds the target acceleration range, it can be determined that the wheel rim has a risk of deformation or cracking, so as to issue a vehicle inspection prompt message so that the user can check the target wheel in time, thereby avoiding the situation where the deformation or cracking of the wheel rim is difficult to find, reducing the safety hazards during the driving of the vehicle, and improving the driving safety of the user. In addition, the target acceleration range here is obtained by using a test road step with a target height and a test road pit with a target depth to perform a driving test on a test vehicle with target vehicle attribute information. In this way, according to the target vehicle attribute information of the vehicle, a test road step with a target height and a test road pit with a target depth are configured accordingly, and a test vehicle with the target vehicle attribute information is used for driving test to obtain the target acceleration range, which helps to ensure the adaptability and effectiveness of the target acceleration range, and further effectively improves the timeliness of vehicle safety detection.
