Description

Technical Field

[0001] This application relates to the field of tire monitoring technology, specifically to an adaptive tire pressure monitoring method, an adaptive tire pressure monitoring device, a vehicle tire alarm method, and a vehicle. Background Technology

[0002] As the automotive industry matures, intelligent vehicles have become a major trend. With increasing usage scenarios, people have more diverse needs and are placing greater emphasis on vehicle safety. Occasionally, vehicles encounter low tire pressure due to tire leaks, which seriously affects driving safety. Currently, national regulations mandate that newly launched passenger vehicles must be equipped with tire pressure monitoring systems (TPMS). However, due to cost considerations, most models only use indirect TPMS, while mid-to-high-end models mostly use direct TPMS. Indirect TPMS calculates the wheel speed difference based on wheel speed sensor signals to determine whether to issue an alarm. Its main drawback is poor accuracy, prone to false alarms, or failing to report problems. Direct TPMS, on the other hand, uses tire pressure sensors at each wheel to determine whether the tire pressure of each wheel is abnormal based on the uploaded tire pressure signal values ​​and issues an alarm accordingly, offering high accuracy.

[0003] Vehicles equipped with direct tire pressure monitoring systems typically have four tire pressure sensors, each mounted on one of the four wheels, and each sensor provides a unique tire pressure value. Newly manufactured tire pressure sensors are in factory mode and do not function. Installing the sensors requires removing the wheels and installing the sensors in the valve core positions. After installation, use the tire pressure lever to activate the sensors, putting them into non-factory mode, and read their ID values. Open the diagnostic tool and access the tire pressure matching module in the vehicle's control panel. Write the corresponding tire pressure ID values ​​to each wheel according to their respective positions. Tire pressure matching is now complete. Once the vehicle reaches a certain speed, the tire pressure monitoring system will be activated.

[0004] However, in northern regions, due to the icy and snowy weather in winter, almost all vehicles switch from snow tires to regular tires during the winter-to-summer transition. Each switch requires tire pressure adjustment, meaning that under normal circumstances, tire pressure adjustment needs to be performed at least twice a year, which is time-consuming, labor-intensive, and costly. Therefore, it is necessary to develop a tire pressure monitoring system that automatically performs tire pressure adjustment after changing all four tires, eliminating the need for manual adjustment when switching to snow tires.

[0005] Therefore, there is a need for a technical solution to address or at least mitigate the aforementioned shortcomings of existing technologies. Summary of the Invention

[0095] Determine if the vehicle speed exceeds a preset speed threshold and if the time exceeding the preset speed threshold exceeds a preset time. If so, then...

[0096] The vehicle's movement is determined to meet the first preset condition.

[0097] The following examples further illustrate this application in detail. It is understood that these examples do not constitute any limitation on this application.

[0098] In this embodiment, the tire pressure monitoring mode includes the normal tire pressure monitoring mode and the snow tire pressure monitoring mode. It is understood that in other embodiments, tire pressure monitoring modes for other types of tires may also be included.

[0099] In this embodiment, a four-wheeled vehicle is used as an example, therefore, the number of tires is four.

[0100] In this embodiment, since there are only normal tire pressure monitoring modes and snow tire pressure monitoring modes, the preset ID groups also include two groups, each group including 4 preset ID information (the same as the number of tires used by the vehicle).

[0101] Step 1: Determine whether the tire pressure sensor signal has been received. Specifically, the vehicle controller checks the four tire pressure sensors based on the received tire pressure sensor signal. First, before implementing the monitoring method of this application, it is necessary to determine whether the tire pressure sensor signal transmitted by each tire pressure sensor (at least one tire pressure sensor is equipped on each tire) can be received. If it cannot be received, the tire pressure sensor may be faulty or other parts of the vehicle may be faulty. In this case, an alarm needs to be triggered.

[0102] If signals from each tire pressure sensor are received, proceed to step 2 to obtain the ID information of each tire.

[0103] Step 3: Obtain the preset tire ID database. The tire ID database includes at least two preset ID groups and a tire pressure monitoring mode. Each preset ID group includes multiple preset ID information, and each preset ID information is different. In this embodiment, the preset ID groups of this application are two groups, namely the ordinary tire preset ID group and the snow tire preset ID group. Each group includes 4 preset ID information (for example, the ordinary tire preset ID group includes the first preset ID (for example, ID number 001), the second preset ID (for example, ID number 002), the third preset ID (for example, ID number 003), and the fourth preset ID (for example, ID number 004), and the snow tire preset ID group includes the fifth preset ID (for example, ID number 005), the sixth preset ID (for example, ID number 006), the seventh preset ID (for example, ID number 007), and the eighth preset ID (for example, ID number 008)).

[0104] The ID information of each tire is compared with the preset ID information in each preset ID group, and the tire pressure of each tire is monitored based on the comparison results.

[0105] Specifically, the ID information of each tire is compared with the preset ID information in each preset ID group, and tire pressure monitoring is performed on each tire based on the comparison results, including:

[0106] The ID information of each tire is compared one by one with the preset ID information in each preset ID group. If the ID information of each tire successfully matches the preset ID information in one of the preset ID groups, then...

[0107] Obtain the tire pressure monitoring mode associated with the preset ID group and perform tire pressure monitoring according to the tire pressure monitoring mode.

[0108] For example, each tire in use on a vehicle has its own tire ID information. For instance, taking a certain vehicle as an example, the ID information of its left front wheel is 001, the ID information of its right front wheel is 002, the ID information of its left rear wheel is 003, and the ID information of its right rear wheel is 004. After comparing it with the above-mentioned preset ID group of ordinary tires, it is found that they are all the same. Then, the tire pressure monitoring mode associated with the preset ID group is obtained and tire pressure monitoring is performed according to the tire pressure monitoring mode, that is, the ordinary tire pressure monitoring mode is obtained for monitoring.

[0109] Assuming the vehicle has been driven for a period of time, after replacing the original regular tires with snow tires, the above steps can be repeated. For example, after replacing with snow tires, the ID information of the left front wheel is 005, the ID information of the right front wheel is 006, the ID information of the left rear wheel is 007, and the ID information of the right rear wheel is 008, which is the same as the preset ID group of snow tires. Therefore, the snow tire pressure monitoring mode is used for monitoring.

[0110] In some embodiments, there may be instances where the tire ID information exists in the preset tire ID database but does not match.

[0111] In one embodiment, the ID information of each tire is processed as follows: It is determined whether the tire's ID information corresponds to a preset ID; if so, then...

[0112] Determine whether each tire's ID information has a corresponding preset ID information (for example, in one embodiment, the ID information of the left front wheel is 001, the ID information of the right front wheel is 002, the ID information of the left rear wheel is 003, and the ID information of the right rear wheel is 007. In this case, by comparing with the preset tire ID database, it is found that the ID information of the right rear wheel belongs to the same preset ID group for snow tires, but the other wheels belong to the preset ID group for ordinary tires, indicating that the right rear wheel is a snow tire and is different from the other tires). If so, then...

[0113] Obtain the tire pressure monitoring mode associated with the preset ID information corresponding to the ID information of each tire;

[0114] Based on the obtained tire pressure detection modes, obtain the tire type corresponding to the ID information of each tire;

[0115] First prompt information is generated based on each tire type.

[0116] In this embodiment, the first prompt information can be either voice information or display information. For example, if it is voice information, it can be a voice broadcast that announces the real ID of each tire and specifically indicates the ID information that does not belong to the same preset ID group as the ID information of other tires. For example, the broadcast text can be: "Among the tires of the vehicle, the ID information of the left front wheel is 001, the ID information of the right front wheel is 002, the ID information of the left rear wheel is 003, and the ID information of the right rear wheel is 007. The ID information of the right rear wheel does not belong to the preset ID group of ordinary tires."

[0117] The above text can also be displayed in the human-computer interaction interface.

[0118] In other embodiments, some tire ID information may not exist in the preset tire ID database. In this case, the following solution is adopted:

[0119] Determine if each tire's ID information has a corresponding preset ID information; if not, then...

[0120] The ID information of the tires with corresponding preset ID information is obtained from the ID information of each tire and used as the tire information to be searched.

[0121] Obtain the tire pressure monitoring mode associated with the preset ID information corresponding to each tire information to be searched;

[0122] Based on the obtained tire pressure detection modes, obtain the tire type corresponding to the ID information of each tire;

[0123] First prompt information is generated based on each tire type;

[0124] A second prompt message is generated based on the ID information of tires with corresponding preset ID information that do not have uniformity.

[0125] In this embodiment, assuming that the ID information of the left front wheel is 001, the ID information of the right front wheel is 002, the ID information of the left rear wheel is 003, and the ID information of the right rear wheel is 009, at this time, by comparing with the preset tire ID database, it is found that the ID information of the right rear wheel does not exist. Then, a second prompt message is generated based on the ID information of the tires that do not have corresponding preset ID information.

[0126] The second prompt is similar to the first prompt; both can be voice messages or display messages. In actual broadcasting, the second prompt can read the following:

[0127] The ID information for the left front wheel is 001, the ID information for the right front wheel is 002, the ID information for the left rear wheel is 003, and the ID information for the right rear wheel is 009. Among them, the right rear wheel is an unregistered wheel.

[0128] In this embodiment, before determining whether a tire pressure sensor signal has been received, the adaptive tire pressure monitoring method further includes:

[0129] Determine if a monitoring command has been received; if so, then...

[0130] Determine whether a tire pressure sensor signal has been received.

[0131] For example, the adaptive tire pressure monitoring method of this application can be triggered according to the user's control, such as by the user activating the adaptive tire pressure monitoring method of this application through a button or voice interaction.

[0132] Understandably, this application can also be activated automatically. For example, if it is determined that no monitoring instruction has been received, but the vehicle has already started moving, then it is determined whether the vehicle's movement meets the first preset condition. If so, then...

[0133] Determine whether a tire pressure sensor signal has been received.

[0134] Specifically, determining whether a vehicle's driving meets the first preset condition includes:

[0135] Determine if the vehicle speed exceeds a preset speed threshold and if the time exceeding the preset speed threshold exceeds a preset time. If so, then...

[0136] The vehicle's movement is determined to meet the first preset condition.

[0137] In this embodiment, determining whether the vehicle's movement meets the first preset condition includes:

[0138] If the vehicle body controller receives a signal from any tire pressure sensor for 10 minutes, it is considered compliant; otherwise, it is considered ineligible.

[0139] In this embodiment, the tire pressure monitoring of this application includes monitoring the current temperature of the tire and monitoring tire pressure information.

[0140] In this implementation, each tire pressure ID is unique and is used by the vehicle controller to identify the tire pressure of different wheels.

[0141] In this embodiment, the signals sent by each tire pressure sensor are high-frequency signals.

[0142] In this embodiment, the preset tire ID database needs to be preset in advance, for example as follows:

[0143] During the vehicle's production line process, the tire pressure of regular tires must be matched (tire pressure matching for snow tires is not mandatory at the factory).

[0144] The factory EOL equipment is used to perform tire pressure matching for ordinary tires (default). The tire pressure IDs of the left front, left rear, right rear, and right front ordinary tires are read in sequence (e.g., 001, 002, 003, and 004 in the above embodiment). The tire pressure IDs are written to the body controller through the diagnostic service to form a preset ID group for ordinary tires.

[0145] Once the tire pressure matching test process is completed, the tire pressure matching for ordinary tires is finished.

[0146] The tire pressure matching process for snow tires is the same as for regular tires. Select "snow tire pressure matching" on the EOL (Effective Online Maintenance) device or after-sales diagnostic tool. The matching process can be performed at the factory or by a 4S dealership. At a 4S dealership, tire pressure matching can be done using an after-sales diagnostic tool.

[0147] The infotainment controller's main screen displays tire pressure status, including snow tires and regular tires. When tire pressure matching is not performed, both displays are blank.

[0148] After tire pressure matching is completed, the tire pressure monitoring system for regular tires is enabled by default, displaying a message that the tire pressure has been successfully matched and the corresponding display item is in the enabled state; the tire pressure monitoring display item for snow tires is disabled by default. The corresponding tire mode signals and tire information are all sent by the vehicle controller, and the instrument panel and main unit display them according to the signals.

[0149] After the tire pressure of the regular tires and snow tires is matched, the tire pressure monitoring of the regular tires is enabled by default.

[0150] In this embodiment, tire pressure monitoring is performed on each tire to monitor its temperature and pressure, and the tire pressure information of the monitored tires is displayed on an instrument.

[0151] For example, if the tire pressure monitoring mode is set to normal tire pressure monitoring mode, the instrument panel will display normal tire pressure information, and the main unit will display that the current mode is normal tire mode.

[0152] If the tire pressure monitoring mode is set to snow tire pressure monitoring mode, the instrument panel will display snow tire pressure information, and the main unit will display that the current mode is snow tire mode.

[0153] In this embodiment, the first and second prompt messages can also be alarm messages. For example, when the first and / or second prompt messages appear, the tire pressure monitoring system is considered to be abnormal, and a tire pressure monitoring system malfunction is reported.

[0154] In this embodiment, during tire pressure monitoring, the tire pressure sensor periodically sends a tire pressure signal (high frequency) at a fixed frequency. The radio frequency receiving module receives the tire pressure signal and transmits it to the body controller, which monitors the signal in real time. If low tire pressure, high temperature, or tire pressure signal loss occurs, the body controller sends an alarm signal. Based on the signals sent by the body controller, the instrument panel displays the individual tire pressure status (including tire pressure and temperature) of each of the four wheels in real time. If low pressure occurs, the body controller issues a low pressure alarm for the corresponding wheel via the instrument panel; if high temperature occurs, the corresponding wheel issues a high temperature alarm; if the tire pressure signal is lost, a tire pressure system malfunction is indicated, and the faulty wheel is displayed. The tire pressure display on the mobile app is normal and consistent with the tire pressure display on the instrument panel.

[0155] This application also provides an adaptive tire pressure monitoring device, which includes a tire pressure signal judgment module, a tire ID information acquisition module, a database acquisition module, and a comparison module. The tire pressure signal judgment module is used to determine whether a tire pressure sensor signal is received; the tire ID information acquisition module is used to acquire the ID information of each tire; the database acquisition module is used to acquire a preset tire ID database, which includes at least two preset ID groups and a tire pressure monitoring mode. Each preset ID group includes multiple preset ID information, and each preset ID information is different; the comparison module is used to compare the ID information of each tire with each preset ID information in each preset ID group, and perform tire pressure monitoring on each tire based on the comparison results.

[0156] Based on the traditional direct tire pressure monitoring system, this application optimizes the processing logic of the vehicle controller, changing the process from writing only the tire pressure IDs of four ordinary tires when matching tire pressure to simultaneously writing the tire pressure IDs of two sets of vehicle tire pressure sensors.

[0157] The vehicle body controller of this application can adaptively switch the tire pressure monitoring system to match the current tire mode based on the actual received tire pressure sensor signal, eliminating the need for an additional tire pressure matching process when changing snow tires and regular tires.

[0158] This application also provides a vehicle tire warning method, the vehicle tire warning method comprising:

[0159] Tire pressure monitoring is performed according to the adaptive tire pressure monitoring method described above;

[0160] When the first prompt information and / or the second prompt information are obtained by tire pressure monitoring according to the adaptive tire pressure monitoring method, a preset image database is obtained. The preset image database includes at least one tire mark image and preset ID information, with one preset ID information corresponding to one tire mark image.

[0161] Obtain tire images from each wheel of the vehicle;

[0162] Perform the following operations on the tire image information for each wheel:

[0163] The similarity between the tire image information and each tire mark image is calculated to obtain the various similarity values;

[0164] Determine if any similarity value exceeds a preset similarity threshold; if so, then...

[0165] Obtain the preset ID information corresponding to tire marking images whose similarity value exceeds a preset similarity threshold;

[0166] Determine whether the ID information of the wheel is the same as the preset ID information corresponding to a tire mark image whose similarity value exceeds a preset similarity threshold. If not, then...

[0167] The tire image information is displayed on the vehicle's in-vehicle display.

[0168] For example, when the first and / or second warning messages are obtained through the adaptive tire pressure monitoring method described above, it indicates that one of the tires has a problem. If the user is on the highway, they may not be able to get out of the car immediately to check, but they want to know whether the tire actually has a problem or it is a false alarm, i.e., a problem with some signals or monitoring logic. In this case, the vehicle's built-in camera (there can be multiple cameras, as long as they can capture images of each tire) can be used to compare the tire images with the tire marking images to determine whether there is a problem with the tire or it is actually a false alarm, and to identify which tire has a problem and the current tire image status.

[0169] For example, we can assign a special mark to each tire. For instance, we can paint or use other methods to give each tire a unique mark. For example, paint the number 1 on the left front tire and the number 2 on the right front tire. Then, we compare this mark with the tire marking image (for example, the tire marking image is a tire with a 1). If the comparison is successful, it proves that the tire is fine. If the comparison fails, it means that the tire is not the one that should be on the wheel. In this case, the photo of the tire is displayed on the in-vehicle display, so that the user can understand the specific situation. For example, if a good tire is stolen and replaced with a bad tire after the vehicle has been parked overnight, the user can find out the situation in this way.

[0170] This application also provides a vehicle, which includes a camera device, an adaptive tire pressure monitoring device, and a vehicle tire warning device. The camera device is used to capture tire image information of each tire; the adaptive tire pressure monitoring device is used to perform the adaptive tire pressure monitoring method as described above; and the vehicle tire warning device is used to perform the vehicle tire warning method as described above.

[0171] In this embodiment, the camera device can be installed near the tire to take pictures of the tire.

[0172] Understandably, since the tire is rotating, multiple photos can be taken during the shooting process to cover the entire rotation cycle of the tire.

[0173] In this embodiment, the tire marking images in the preset image database are also captured by various camera devices used to photograph tires. Therefore, the angle of each tire marking image is the same as the angle of the tire image information captured by the camera device, which makes comparison easier.
