[0059] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0060] Based on the problems mentioned in the above background technology, in the related technology, in the tire blowout detection scheme, the tire status data (including tire pressure, tire temperature, tire speed, tire acceleration, etc.) can be obtained through TPMS (Tire Pressure Monitoring System), and then these tire status data are integrated and stored, and the algorithm is used to obtain the tire status at this time or predict the possible tire status in a short time, and then determine whether the vehicle has a tire blowout. However, a tire blowout often only occurs in about 0.1 seconds. If the detection frequency of TPMS is not increased, the tire blowout control process cannot be carried out in time. But at the same time, if the detection frequency of TPMS is too high, it will bring higher energy loss, increase the operating cost of the vehicle, reduce the environmental performance of the vehicle, and cannot take into account the detection requirements of "high precision" and "low energy consumption".

[0061] In this regard, the present application provides a tire blowout control method, which is applied to an electronic device, which may be, for example, a controller, and which may be, for example, an electronic control unit (ECU) of a vehicle. Figure 1 The tire blowout control method provided in the embodiment of the present application includes steps 100 to 200, which are described in detail below.

[0062] Step 100, determining a receiving state of a tire blowout signal and acquiring tire state data, wherein the tire blowout signal is triggered when a vehicle has a tire blowout.

[0063] Step 200, performing tire blowout control processing according to the received status and tire status data.

[0064] In this embodiment, the tire blowout signal is a signal that is automatically triggered when the vehicle has a tire blowout. The automatic triggering of the tire blowout signal can be achieved through a corresponding device structure, which is not limited here. The receiving state of the tire blowout signal can indicate that the tire blowout signal is not received, the tire blowout signal is received, etc. For example, when the receiving state is a first preset state, it indicates that the tire blowout signal is not received, and when the receiving state is a second preset state, it indicates that the tire blowout signal is received. The first preset state can be one of a high level signal and a low level signal, and the second preset state can be, for example, the other of a high level signal and a low level signal.

[0065] Tire status data refers to status information of the tires of the vehicle, and may include, for example, at least one of tire pressure information, tire temperature information, tire speed information, and tire acceleration information of the tires in the vehicle. The acquisition of tire status data may also be achieved through a corresponding device structure, which is not limited here.

[0066] The tire blowout control process refers to the countermeasures that can be executed when a vehicle has a tire blowout, so as to avoid safety accidents caused by the tire blowout. The specific measures in the tire blowout control process can be preset based on actual needs and are not limited here.

[0067] It can be understood that this embodiment performs tire blowout control processing based on the receiving status and tire status data, so that the execution of the tire blowout control processing can take into account factors of more dimensions, and then trigger the execution action of the tire blowout control processing from multiple dimensions respectively, so that the execution of the tire blowout control processing can be more timely.

[0068] It can be seen that through the above technical solution, by determining the receiving state of the tire blowout signal and obtaining the tire status data, the tire blowout control processing is performed based on the integrated receiving state and tire status data, so that the tire blowout situation can be detected in time and the corresponding tire blowout control processing can be performed. Compared with the tire blowout control processing performed by the tire pressure monitoring system, the tire blowout control processing of the embodiment of the present application is more timely and can more fully and efficiently detect the tire blowout situation of the vehicle tire. In addition, the monitoring frequency of the tire pressure monitoring device for monitoring the tire status data can be set lower, thereby reducing energy consumption while ensuring safety.

[0069] In some embodiments, a tire blowout signal can be triggered by a tire blowout detection device, that is, the tire blowout detection device will automatically trigger a tire blowout signal when the vehicle has a tire blowout, thereby switching the receiving state of the tire blowout signal from a state indicating that the tire blowout signal has not been received to a state in which the tire blowout signal has been received, for example, switching the receiving state of the tire blowout signal from a first preset state to a second preset state. The tire status data can be obtained by monitoring a tire pressure monitoring device, which has at least part or all of the functions of a tire pressure monitoring system (TPMS) to achieve tire pressure monitoring. In one embodiment, the tire pressure monitoring device is a tire pressure monitoring system. See Figure 2 The tire pressure monitoring device and the tire blowout detection device are connected in parallel to the electronic device so as to respectively implement the following two steps: determining the receiving state of the tire blowout signal and obtaining the tire state data.

[0070] In some embodiments, a structure of a tire blowout detection device is exemplified. Figure 3 , Figure 3 The figure is a half-section view of a tire blowout detection device. The tire blowout detection device is a bilaterally symmetrical structure, and the structure shown on the right is a symmetrical section of the structure shown on the left. The tire blowout detection device includes: a housing 1, a second chamber 2, a first chamber 3, a buckle structure 4, a connecting hole 5, an air passage 6, a bottom plate 7, a first conductive baffle 11, a conductive sheet 12, a piston 13, and a spring 14.

[0071] The housing 1 includes a communication hole 5, and a receiving cavity is formed in the housing 1. The conductive sheet 12 can separate the receiving cavity into a first chamber 3 and a second chamber 2, and the first chamber 3 is connected to the communication hole 5. The conductive baffle includes a first conductive baffle 11 and a second conductive baffle (not shown), the second conductive baffle and the first conductive baffle 11 are arranged symmetrically, and the first conductive baffle 11 and the second conductive baffle are fixed to the first chamber 3 or the second chamber 2. The conductive sheet 12 can be driven to connect the first conductive baffle 11 and the second conductive baffle, or disconnect the first conductive baffle 11 and the second conductive baffle.

[0072] Since the tire burst detection device includes the connecting hole 5 and the air passage 6, the first chamber 3 can be connected to the tire carcass through the connecting hole 5, and the second chamber 2 can be connected to the tire carcass through the air passage 6. Therefore, when the tire is not scratched or punctured, the driving force provided to the conductive sheet 12 by the first chamber 3 is equal to the driving force provided to the conductive sheet 12 by the second chamber 2. At this time, the conductive sheet 12 is in a stable state, and the conductive baffle is in a disconnected state, that is, Figure 2 As shown in , the switch of the tire blowout detection device is in the disconnected state when the vehicle has no tire blowout.

[0073] When the tire is scratched or punctured, the air pressure of the tire body drops, driving the air pressure of the first chamber 3 and the second chamber 2 to drop. Since the size of the connecting hole 5 is larger than the size of the air passage 6, the driving force provided to the conductive sheet 12 by the air pressure of the first chamber 3 is smaller than the driving force provided to the conductive sheet 12 by the second chamber 2, thereby enabling the elastic member to drive the conductive sheet 12 to approach the first conductive baffle 11 and the second conductive baffle, so that the conductive sheet 12 can connect the first conductive baffle 11 and the second conductive baffle, so that the first conductive baffle 11 and the second conductive baffle are in a connected state, that is, Figure 2 The switch of the tire blowout detection device is in a closed state when the vehicle has a tire blowout, and at this time, the tire blowout signal can be automatically output to the electronic device.

[0074] The tire blowout detection device effectively realizes tire blowout monitoring through the change of air pressure and the driving of the conductive sheet 12, and no longer needs to use a permanent magnet piston, a magnetic signal receiving device and a non-magnetic material shell, which further simplifies the overall structure of the tire blowout detection device, reduces the number of parts of the tire blowout detection device, and significantly reduces the manufacturing cost of the tire blowout detection device.

[0075] In some embodiments, a tire blowout control process is performed based on the receiving state and tire status data, which may include: if the receiving state indicates that a tire blowout signal has not been received, it indicates that it is impossible to determine whether a tire blowout has occurred based on the receiving state of the tire blowout signal at this time, and therefore, it is possible to further determine whether a tire blowout control process is required based on the periodically acquired tire status data, so that when it is determined that a tire blowout control process is required, a tire blowout control process is performed. Among them, the periodically acquired tire status data is obtained by periodically monitoring the tire pressure monitoring device at a preset fixed frequency. If the receiving state indicates that a tire blowout signal has been received, it indicates that a tire blowout can be determined based on the receiving state of the tire blowout signal at this time, and therefore a tire blowout control process can be directly performed, so that the execution of the tire blowout control process is more timely.

[0076] In some embodiments, since a tire blowout signal may be triggered by mistake in some special cases, a secondary determination may be made on whether a tire blowout has occurred. Specifically, if the receiving state indicates that a tire blowout signal has not been received, performing a tire blowout control process may include: if the receiving state indicates that a tire blowout signal has been received, immediately controlling the tire pressure monitoring device to reacquire tire status data; determining whether a tire blowout control process is required based on the reacquired tire status data, and performing a tire blowout control process when it is determined that a tire blowout control process is required, thereby achieving a secondary determination on whether a tire blowout has occurred and avoiding erroneous execution of the tire blowout control process.

[0077] In some embodiments, determining whether a tire blowout control process is required based on the reacquired tire status data may include: determining the tire pressure deviation value of the vehicle based on the tire pressure information in the reacquired tire status data, wherein the tire pressure deviation value represents the degree of deviation of the vehicle's tire pressure from the standard; determining whether a tire blowout control process is required based on the tire pressure deviation value of the vehicle, that is, making a secondary determination on whether a tire blowout has occurred based on the tire pressure deviation value of the vehicle. For example, when the tire pressure deviation value of the vehicle is too large, it indicates that the tire pressure of at least one tire of the vehicle has decreased due to a tire blowout, and therefore it can be determined that a tire blowout has occurred and a tire blowout control process is required. For another example, when the tire pressure deviation value of the vehicle is not too large, it indicates that the vehicle has not experienced a tire blowout and the tire pressure has decreased, and therefore it can be determined that a tire blowout has not occurred and a tire blowout control process is not required.

[0078] In some embodiments, similar to the step of determining whether a tire blowout control process is required based on the re-acquired tire status data, determining whether a tire blowout control process is required based on the periodically acquired tire status data may include: determining a tire pressure deviation value of the vehicle based on tire pressure information in the periodically acquired tire status data; and determining whether a tire blowout control process is required based on the tire pressure deviation value of the vehicle. The specific details are not repeated here.

[0079] In some embodiments, the tire pressure deviation value of the vehicle may include the relative deviation of the tire pressure values ​​of any two tires of the vehicle. It is understandable that when the vehicle has no tire blowout, the tire pressures of different tires in the vehicle are often similar, but when the vehicle has a tire blowout, the tire pressures of different tires in the vehicle may have a relative deviation.

[0080] In some embodiments, the above-mentioned arbitrary two tires may be at least two of the left front wheel, the right front wheel, the left rear wheel, and the right rear wheel of the vehicle. When the vehicle has no tire burst, the front and rear tires will have a certain difference in tire pressure due to the gravity factor of the vehicle body powertrain, but the tire pressures of the left front wheel and the right front wheel are often similar, and the tire pressures of the left rear wheel and the right rear wheel are often similar, so the arbitrary two tires may be the left front wheel and the right front wheel, or the left rear wheel and the right rear wheel.

[0081] In some embodiments, a relative deviation of tire pressure values ​​can be determined for the left front wheel and the right front wheel of the vehicle, and a relative deviation of tire pressure values ​​can also be determined for the left rear wheel and the right rear wheel of the vehicle. Since the tires that have a blowout have a certain randomness, the maximum value of the relative deviation of the tire pressure values ​​of the left front wheel and the right front wheel and the relative deviation of the tire pressure values ​​of the left rear wheel and the right rear wheel can be used as the tire pressure deviation value of the vehicle to ensure that the blowout control process can be executed in time.

[0082] In some embodiments, the relative deviation of the tire pressure values ​​of any two tires can be determined based on the absolute value of the difference between the tire pressure values ​​of any two tires and the maximum value of the tire pressure values ​​of any two tires. For example, the ratio between the absolute value of the difference between the tire pressure values ​​of any two tires and the maximum value of the tire pressure values ​​of the any two tires can be used as the relative deviation of the tire pressure values ​​of the any two tires. The calculation formula of the relative deviation α can be, for example:

[0083] α=|P1-P2| / max(P1,P2)

[0084] Among them, P1 is the tire pressure value of one tire, and P2 is the tire pressure value of the other tire.

[0085] In some embodiments, determining whether a tire blowout control process is required based on the tire pressure deviation value of the vehicle may include: if the tire pressure deviation value is greater than a first preset threshold value, determining that a tire blowout control process is required, the first preset threshold value may be, for example, 15%; if the tire pressure deviation value is less than or equal to the first preset threshold value, indicating that the tire pressure deviation value is within a normal range, and therefore determining that a tire blowout control process is not required.

[0086] In some embodiments, when a vehicle has a tire blowout, the tire may leak air slowly or rapidly, so corresponding tire blowout control processing may be performed according to different situations. Specifically, if the tire pressure deviation value is greater than the first preset threshold value, after determining that a tire blowout control processing is required, it may also include: based on the size of the tire pressure deviation value, determining a target control strategy among multiple preset tire blowout control strategies, that is, when the size of the tire pressure deviation value is different, the selected preset tire blowout control strategy may also be different; performing tire blowout control processing according to the target control strategy to avoid performing excessive and unnecessary tire blowout control processing.

[0087] In some embodiments, multiple preset tire blowout control strategies may include, for example, at least one of the following: a strategy for outputting tire blowout prompt information, a strategy for controlling the vehicle's braking system to perform corresponding processing, a strategy for controlling the vehicle's steering system to perform corresponding processing, a strategy for controlling the vehicle's body suspension system to perform corresponding processing, etc. For example, when a tire is leaking slowly, a strategy for outputting tire blowout prompt information may be selected to avoid excessive and unnecessary tire blowout control processing.

[0088] In some embodiments, based on the size of the tire pressure deviation value, determining a target control strategy among multiple preset tire blowout control strategies may include: if the tire pressure deviation value is greater than a first preset threshold value and less than or equal to a second preset threshold value, determining the target control strategy as a strategy of outputting a first tire blowout prompt information to prompt the user that the vehicle has a tire blowout, wherein the second preset threshold value may be, for example, 15%. If the tire pressure deviation value is greater than the second preset threshold value, determining the target control strategy as a strategy of outputting a second tire blowout prompt information, and controlling at least one of the vehicle's braking system, steering system, and body suspension system to perform corresponding processing, so as to assist the user in safely driving the vehicle and safely stopping the vehicle while prompting the user that the vehicle has a tire blowout. The first tire blowout prompt information and the second tire blowout prompt information may be the same or different; if the first tire blowout prompt information and the second tire blowout prompt information are different, corresponding prompts may be provided for different degrees of risks caused by tire blowouts.

[0089] In some embodiments, see Figure 4 , corresponding to a plurality of preset tire blowout control strategies, the tire blowout control process performed according to the preset tire blowout control strategy may include at least one of the following: outputting tire blowout prompt information (for example, including first tire blowout prompt information, second tire blowout prompt information, etc.) through the vehicle, controlling the vehicle's braking system to perform speed reduction processing, controlling the vehicle's steering system to perform steering stabilization processing, and controlling the vehicle's body suspension system to perform suspension height adjustment processing. Among them, the speed reduction processing, steering stabilization processing, and suspension height adjustment processing may be implemented by the vehicle's intelligent driving system.

[0090] In the step of outputting tire blowout prompt information through the vehicle, for example, a prompt screen, a prompt voice, a prompt light effect, etc. of the vehicle tire blowout can be output to the passengers in the vehicle and / or the environment outside the vehicle through the vehicle. The prompt light effect output to the environment outside the vehicle can be, for example, the double flash light effect of the vehicle to warn the external vehicles in the environment outside the vehicle to avoid secondary accidents. In the step of controlling the braking system of the vehicle to perform a deceleration process, for example, the vehicle can be automatically controlled to slow down in the form of "point braking". In the step of controlling the steering system of the vehicle to perform a steering stability process, for example, the steering wheel can be controlled to prevent the user in the vehicle from violently turning the steering wheel and causing the vehicle to lose control. In the step of controlling the body suspension system of the vehicle to perform a suspension height adjustment process, since the height of some suspensions in the vehicle may change after the vehicle tire blows, the height of at least some suspensions in the vehicle can be adjusted to keep different suspensions in the vehicle at the same horizontal height to avoid the vehicle tilting and losing control. Among them, the height of different suspensions in the vehicle can be detected by the body height sensor set at the corresponding suspension.

[0091] In some embodiments, the deceleration process may include: allocating different braking torques to the vehicle's flat tire side and non-flat tire side. For example, in the process of automatically controlling the vehicle to slowly decelerate in the form of "point braking", the braking torque of the flat tire side may be smaller than the braking torque of the non-flat tire side to avoid the vehicle swaying due to braking after a flat tire.

[0092] In some embodiments, the steering stabilization process may include: increasing the damping when turning the steering wheel of the vehicle to make it more difficult to turn the steering wheel, so as to prevent the user in the vehicle from violently turning the steering wheel and causing the vehicle to lose control. It is understandable that after a tire bursts, the vehicle body will sway to the side of the tire burst, and combined with the nervous mentality of the vehicle driver, the vehicle may sway due to violently turning the steering wheel. Therefore, the damping when the steering wheel is turned can be increased to stabilize the direction of the vehicle body, and the yaw torque can be adjusted together with the braking system to maintain the stability of the vehicle body.

[0093] In some embodiments, since after a vehicle has a tire blowout, the suspension height on the blown tire side may be lowered and the suspension height on the non-blown tire side may be raised, the suspension height adjustment process may include: raising the suspension height on the blown tire side of the vehicle, lowering the suspension height on the non-blown tire side of the vehicle, at least one of so that different suspensions in the vehicle are maintained at the same level, so as to stabilize the vehicle body, control the center of gravity of the vehicle, and prevent the vehicle from tilting and losing control.

[0094] In some embodiments, see Figure 5 , an example is given to illustrate some logic in the tire blowout control method. Specifically, after determining the receiving state of the tire blowout signal, if the receiving state indicates that the tire blowout signal has not been received, the tire blowout detection device will periodically obtain tire state data, and at this time, the tire pressure deviation value of the vehicle can be determined based on the periodically obtained tire pressure data.

[0095] When the tire pressure deviation value is ≤5%, due to differences in vehicle driving conditions, summer temperature changes, and slight differences in tire inflation, there may be an error of about 0.1 bar between the left and right tire pressures. This is normal and no tire blowout control will be performed at this time.

[0096] When 5%≤tire pressure deviation value≤15%, the tire pressure deviation value exceeds the normal range, which may cause slight disturbance to the vehicle driving and pose certain risks. Therefore, the first tire blowout prompt information can be output to the occupants through the vehicle to inform them of the risk.

[0097] When the tire pressure deviation value is greater than 15%, the tire pressure deviation value exceeds the normal range to a large extent, and the vehicle begins to have the risk of slipping. Therefore, a second tire blowout prompt message can be output through the vehicle, and at the same time, the intelligent driving system can control at least one of the vehicle's braking system, steering system, and body suspension system to assist in deceleration and direction control.

[0098] If the receiving state indicates that a tire blowout signal has been received, it means that the tire pressure has dropped rapidly and the tire has been seriously blown out. In order to ensure the safety of the passengers in the vehicle, the vehicle height sensor set at different suspensions in the vehicle can detect the height difference between different suspensions in the vehicle and directly perform tire blowout control processing.

[0099] According to a second aspect of the present application, an electronic device is provided, which is used to execute the steps in any of the above tire blowout control methods. For example, the electronic device may include:

[0100] A determination module is used to determine the receiving state of a tire blowout signal and obtain tire state data, wherein the tire blowout signal is triggered when a vehicle has a tire blowout;

[0101] The control module is used to perform tire blowout control processing according to the received status and tire status data.

[0102] The electronic device has all the beneficial effects of the above tire blowout control method, which will not be described in detail in this application.

[0103] According to a third aspect of the present application, a computer-readable storage medium is provided, which may include: a read-only memory (ROM), a random access memory (RAM), a disk or an optical disk, etc. A computer program is stored thereon, and the computer program is loaded by a processor to execute the steps in any of the above tire blowout control methods.

[0104] According to a fourth aspect of the present application, a controller is provided, which is used to execute the steps in any of the above tire blowout control methods. For example, the controller may include any of the above electronic devices.
