The tire anti-extrusion apparatus and method according to the present invention may be applied to any suitable vehicle having a tire, such as, but not limited to, motorcycles, cars, buses, trucks, trailers, and the like.

Fig. 1 shows a schematic composition diagram of a vehicle on which a tire anti-squeezing device according to an embodiment of the present invention is mounted or applied. As shown in fig. 1, the vehicle 100 includes a power and transmission system 10, a steering system 20, a braking system 30, and other conventional power and steering systems. Further, the vehicle 100 includes a sensor system 40, an input-output system 50, and a vehicle control system 60.

The sensor system 40 includes various external sensors, such as image sensors, ultrasonic sensors, radar and/or laser sensors, etc., typically disposed on the vehicle 100. The sensor system 40 also includes various internal sensors typically provided on the vehicle 100, such as a speed sensor, an acceleration sensor, a steering angle sensor, a seat pressure sensor, and the like.

The input-output system 50 includes various input devices such as buttons, a touch panel, and the like for inputting user operations, which are generally provided on the vehicle 100, and also includes various output devices such as speakers, a display, and the like that can output information to the user. Here, the input-output system 50 also includes keys of the vehicle 100. In particular, the key of the vehicle 100 may have a sound emitting device and a light emitting device. Further, the input-output system 50 may also include a mobile terminal associated with the vehicle 100, such as a cell phone, tablet computer, or the like. The keys and mobile terminals may communicate with one or more systems of the vehicle 100 by way of a wireless connection or a wired connection. The wireless connection mode can comprise Wi-Fi, a 3G mobile network, a 4G mobile network, Bluetooth and the like. The wired connection may include a system bus, USB, etc.

The vehicle control system 60 may control the operation of the vehicle according to the user's instruction. Further, the vehicle control system 60 may also automatically control the operation of the vehicle based on the detection data of the sensor system 40, if permitted by the user.

The tire anti-crush device according to the embodiment of the present invention can communicate with a plurality of systems of the vehicle 100 and transfer data and signals to each other to realize the function thereof. For example, the tire crush preventer may communicate with the input-output system 50 of the vehicle 100 to output a warning to the driver using a speaker, a display, or the like of the input-output system 50. Other embodiments of the tire anti-squeeze device that communicate with the various systems of the vehicle 100 and communicate data and signals to each other to achieve its function are described in detail below. Further, communication of the tire anti-extrusion device with various systems of the vehicle 100 may be accomplished via a system bus, network, and/or other suitable means.

Fig. 2 shows a block diagram of a tire anti-squeezing device 200 according to an embodiment of the present invention. As shown in fig. 2, the tire anti-squeezing device 200 specifically includes a vehicle state determination module 21, an information acquisition module 22, a determination module 23, and a generation module 24. Hereinafter, the specific configuration and/or function of each module of the tire anti-squeezing device 200 will be specifically described.

The vehicle state determination module 21 is configured to determine whether the vehicle 100 is in a parked state. Specifically, the vehicle state determination module 21 makes the above determination based on one or more of the vehicle speed, the gear state, the engine state, the lock state, the key state, the seat state, and the like. Thus, the vehicle state determination module 21 may be configured to determine that the vehicle 100 is in a parked state when one or more of the following are satisfied: the speed of the vehicle 100 is zero; the gear is switched to a parking gear; the engine is shut down; the vehicle 100 is locked; the keys of the vehicle 100 are pulled out of the keyholes and/or are outside the vehicle; and all seats are unoccupied. In particular implementations, the vehicle state determination module 21 may communicate with the sensor system 40, the vehicle control system 60, and/or corresponding components or parts of the vehicle 100 and obtain corresponding data to determine whether the above conditions are satisfied. For example, the vehicle state determination module 21 may detect whether the key is removed from the key hole and whether the key is outside the vehicle based on the relevant sensor data. In addition, the vehicle state determination module 21 may also detect whether the seat is occupied based on data of the seat pressure sensor.

The information acquisition module 22 is configured to acquire first information and second information in a case where the vehicle 100 is in a parking state, wherein the first information is initial image information of tires of the vehicle 100, and the second information is image information of the tires when the vehicle 100 is in the parking state.

The initial image information of the tire means image information in which the tire is in a normal state (no foreign matter on the tire, no bulge and deformation of the tire, etc.). Specifically, the initial image information of the tire may be image information of the tire at the time of shipment of the vehicle. The initial image information of the tire may be captured by an image sensor such as a camera while the tire is in a normal state and stored in advance. The image information of the tires when the vehicle 100 is in a parked state may be captured by an image sensor such as a camera when the vehicle state determination module 21 determines that the vehicle 100 is in a parked state.

The image sensor for capturing image information of the tire may be an image sensor included in the sensor system 40 of the vehicle 100. The information acquisition module 22 may acquire the second information by communicating with the sensor system 40 in a case where the vehicle 100 is in a parking state. Of course, according to other embodiments, the image sensor may not be the image sensor included in the sensor system 40, but may be an image sensor dedicated to the tire anti-squeezing device 200. The image sensor may be provided at any position of the vehicle 100 where tire image information can be acquired. For example, the image sensor may be disposed inside a tire fender (in the case where the vehicle 100 is mounted with a fender), or on the underside of a rear view mirror. In addition, the number of the image sensors may be set according to actual needs, and the present invention is not particularly limited thereto.

The determination module 23 is configured to determine whether the tire is squeezed based on the first information and the second information. In an exemplary embodiment, the determination module 23 may be configured to compare the first information and the second information to determine the amount of deformation of the tire, and determine that the tire is squeezed when the amount of deformation of the tire is greater than or equal to a predetermined threshold value. The deformation amount of the tire may be an offset amount of an entire line on the tread or sidewall of the tire with respect to its original position, or a relative distance between a vertex of a curve formed by local deformation of a line on the tread or sidewall of the tire and the original position, or the like. Here, the initial position or the home position is a position of the corresponding line or point in the initial image information of the tire.

In a particular embodiment, the determination module 23 first selects at least one line on the tread or sidewall of the tire. The line may be a line at a specified location on the tread or sidewall of the tire. Preferably, the line is one at the edge of the tread or at the centre of the sidewall of the tire; secondly, the determining module 23 determines a first position and a second position of the selected line, wherein the first position is a position of the selected line in the first information, and the second position is a position of the selected line in the second information; then, the determining module 23 calculates the maximum offset of the line according to the first position and the second position; finally, the determination module 23 compares the determined maximum deviation amount with a predetermined threshold value, and determines that the tire is squeezed when the maximum deviation amount is greater than or equal to the predetermined threshold value.

The generation module 24 is configured to generate a warning signal and/or a vehicle control signal if the determination module 23 determines that the tire is squeezed. The warning signal is used to warn the driver of the vehicle 100, and the vehicle control signal is used to control the vehicle 100 to perform an operation of releasing the tire from the squeezing.

The generation module 24 may output a warning signal to the input-output system 50 of the vehicle 100 to issue a warning to the driver. Specifically, the generation module 24 may output the warning signal to a speaker, a display, or the like of the input-output system 50. The speaker or display audibly or visually alerts the driver when a warning signal is received that the tire is being squeezed. The driver can thus operate the vehicle 100 to disengage the tire from the compression. In some embodiments, the generation module 24 may output a warning signal to the keys of the vehicle 100. The key of the vehicle 100 may alert the driver that the tires are squeezed by means of a warning sound or a warning light when the warning signal is received. The driver can thus operate the vehicle 100 to disengage the tire from the compression. In still other embodiments, the generation module 24 may output the warning signal to a mobile terminal, such as a cell phone, tablet, etc., associated with the vehicle 100. When the mobile terminal receives the warning signal, the mobile terminal can remind a driver that the tire is extruded by displaying warning information or giving out warning sound on the display screen. The driver can thus operate the vehicle 100 to disengage the tire from the compression.

Further, as described above, in the event that the tire is squeezed, the generation module 24 is further configured to generate a vehicle control signal for controlling the vehicle 100 to perform an operation to disengage the tire from the squeeze. The generation module 24 may output the vehicle control signal to the vehicle control system 60. The vehicle control system 60 may automatically control the vehicle to perform the operation of removing the tire from compression, subject to the driver's permission. Here, the operation of releasing the tire from the pressing may include at least: steering the wheels without moving the vehicle; moving the vehicle in a direction opposite to the side where the tire is pressed; and moving the vehicle forward or backward.

In a particular embodiment, the determination module 23 is further configured to determine the compressed position of the tire based on the second information in case it is determined that the tire is compressed. For example, the determination module 23 may identify an object in contact with the tire, such as a road surface protrusion like a curb, by computer image processing and identification technology based on the second information, and determine the relative position of the object and the tire. The determination module 23 may determine the pressed position of the tire, e.g., whether the tread or sidewall is pressed, based on the relative position of the object and the tire. The generation module 24 may generate a corresponding warning signal and/or vehicle control signal based on the determined pinched position of the tire.

Specifically, in the event that the sidewall is squeezed, the generation module 24 may generate and output a warning signal to the input-output system 50. The input-output system 50 generates a voice or video prompt similar to "sidewall is squeezed" or the like based on the received warning signal. The driver can take corresponding action based on the voice or video prompt to release the tire from the extrusion. Further, the generation module 24 may generate and output to the vehicle control system 60 a vehicle control signal that turns the wheels without moving the vehicle or moves the vehicle in a direction opposite to the side where the tires are squeezed. The vehicle control system 60 may control the steering system of the vehicle 100 to steer the wheels in a direction opposite to the side where the tires are squeezed without moving the vehicle 100 based on the received vehicle control signal. The steering angle of the wheel may be gradually increased from the small angle until the tire is no longer squeezed. Alternatively, the vehicle control system 60 may control the vehicle 100 to move in a direction opposite to the side where the tire is squeezed to remove the tire from the squeeze based on the received vehicle control signal. The moving distance of the vehicle 100 is generally short, for example, 0.3m, 0.5m, or the like. However, the length of the moving distance is not limited thereto as long as the tire can be made not to be compressed any more. Specifically, the vehicle control system 60 may automatically start the engine, release the electric parking brake, switch gears, turn the steering wheel, control the vehicle to accelerate, decelerate, and brake so that the autonomous vehicle 100 moves the desired distance to disengage the tires from the compression.

In the event that the tread is compressed, the generation module 24 may generate and output a control signal to the vehicle control system 60 that moves the vehicle forward or backward. The vehicle control system 60 may control the vehicle 100 to move forward or backward to disengage the tires from the compression based on the received vehicle control signal. Similarly, the distance that the vehicle 100 moves forward or backward is very short, e.g., 0.2m, 0.3m, etc. However, the length of the moving distance is not limited thereto as long as the tire can be made not to be compressed any more. Specifically, the vehicle control system 60 may automatically start the engine, release the electric parking brake, switch gears, control the vehicle to accelerate, decelerate, and brake so that the autonomous vehicle 100 moves forward or backward a desired distance to disengage the tires from squeezing.

Further, it is conceivable that the vehicle control system 60 monitors the distance between the vehicle body and the surrounding obstacles in real time by the sensor system 40 of the vehicle 100 during the movement of the automatically controlled vehicle 100, and prevents the vehicle 100 from coming into contact with the surrounding obstacles.

Further, it is conceivable that, in the case where the vehicle 100 includes a plurality of wheels, the determination module 23 is capable of determining which specific wheel has its tire squeezed based on the first information and the second information. Also, it is conceivable that the warning signal generated by the generation module 24 contains such information, and that the vehicle control signal generated by the generation module 24 is used to control the vehicle based on such information, accordingly.

Therefore, the tire anti-extrusion device can prevent the tire from being extruded when the vehicle is in a parking state, so that the damage of the tire and the tire burst hidden danger caused by the damage are reduced.

According to other embodiments of the invention, the generation module 24 is configured to generate the warning signal and/or the vehicle control signal only in case the vehicle 100 is about to be parked for a long time.

Specifically, the tire anti-squeezing device 200 according to the present invention may include a second determination module 25 configured to determine whether the vehicle 100 is about to be parked for a long time. Specifically, the second determination module 25 may be provided with a timer, and the timer is started in the case where the determination module 23 determines that the tire is pressed. Subsequently, the second determination module 25 continuously determines whether the tire is pressed at predetermined time intervals. In the case where the tire continues to be pressed for more than a predetermined length of time, the second determination module 25 determines that the vehicle 100 is about to be parked for a long time. In this case, the generation module 24 will generate a warning signal and/or a vehicle control signal. Here, the predetermined length of time may be 60s, 80s, or the like.

Furthermore, the second determination module 25 may be further configured to detect a distance of a key of the vehicle 100 and/or a mobile terminal associated with the vehicle 100 with respect to the vehicle 100 in case the determination module 23 determines that the tire is squeezed. When it is detected that the distance exceeds the predetermined distance, the second determination module 25 determines that the vehicle 100 is about to be parked for a long time. In this case, the generation module 24 will generate a warning signal and/or a vehicle control signal. Here, the predetermined distance may be 300m, 400m, or the like.

Thus, the tire anti-pinching device according to the present invention can alert the driver and/or control the vehicle to avoid pinching of the tire only in the case where the vehicle is about to be parked for a long time, avoid giving a warning and/or automatically control the vehicle when the vehicle is temporarily stopped during use and the tire abuts against a protrusion on the road surface (for example, while waiting for a red light), and cause trouble to the driver.

Further, in the above-described embodiment, the generation module 24 of the tire anti-squeezing device 200 transmits a warning signal to the speaker or display of the vehicle 100 to issue a warning therewith. However, according to other embodiments, the tire anti-squeezing device 200 may be separately provided with an output device such as a speaker or a display to issue a warning therewith. Further, in the above-described embodiment, the generation module 24 of the tire anti-squeezing device 200 transmits a warning signal to the mobile terminal associated with the vehicle 100 to issue a warning therewith. However, according to other embodiments, the tire anti-extrusion device 200 may be directly associated with a mobile terminal to use it to issue a warning.

Further, in the above-described embodiment, the generation module 24 of the tire anti-squeezing device 200 transmits a vehicle control signal to the vehicle control system 60 of the vehicle 100 to automatically control the vehicle 100 to perform the operation of releasing the tire from squeezing therewith. According to other embodiments, the generation module 24 may automatically control the power and drive system, steering system, and braking system of the vehicle 100 directly with vehicle control signals to cause the vehicle 100 to perform the operation of removing tires from compression, without the vehicle control system 60.

Hereinafter, specific steps of implementing the tire anti-extrusion method according to the embodiment of the present invention in the vehicle 100 will be described in detail with reference to the accompanying drawings. FIG. 3 illustrates a flow chart of a method of anti-extrusion of a tire according to an embodiment of the present invention.

In step S20, it is determined whether the vehicle 100 is in a parked state. Specifically, in this step, corresponding data is acquired from the sensor system 40, the vehicle control system 60, and/or corresponding components or parts of the vehicle 100, and the above-described determination is made in accordance with one or more of the speed, the gear state, the engine state, the lock state, the key state, the seat state, and the like of the vehicle 100. Thus, the vehicle 100 is determined to be in a parked state when one or more of the following is satisfied: the speed of the vehicle 100 is zero; the gear is switched to a parking gear; the engine is shut down; the vehicle 100 is locked; the keys of the vehicle 100 are pulled out of the keyholes and/or are outside the vehicle; and all seats are unoccupied.

When it is determined in step S20 that the vehicle 100 is in the parked state, the method proceeds to step S40. In step S40, first information that is initial image information of the tires of the vehicle 100 and second information that is image information of the tires when the vehicle 100 is in a stopped state are acquired. Specifically, first information stored in advance is acquired from an image sensor of the sensor system 40 of the vehicle 100, and the image sensor is caused to take an image of the tire at the present time to acquire second information.

Subsequently, the method proceeds to step S60. In step S60, it is determined whether the tire is pressed. Specifically, in this step, the first information and the second information are compared to determine the amount of deformation of the tire, and it is determined that the tire is squeezed when the amount of deformation of the tire is greater than or equal to a predetermined threshold value. For a specific implementation of this process, see the description of the determination module 23.

In the event that a determination is made in step S60 that the tire is being squeezed, the method proceeds to step S80, wherein a warning signal and/or vehicle control signal is generated. And then, in step S100, a warning signal is output to a speaker or a display of the input-output system 50, a key of the vehicle 100, and/or a mobile terminal associated with the vehicle 100, or the like, to issue a warning to the driver. Further, the method may also output a vehicle control signal to the vehicle control system 60 of the vehicle 100 to automatically control the vehicle 100 to perform the operation of removing the tire from the squeeze in step S120.

In some embodiments, prior to step S120, the method further includes step S90, wherein a confirmation request is output to the driver asking the vehicle control system 60 to confirm whether the vehicle is permitted to automatically control the operation of the vehicle to remove tires from compression, hi particular, a confirmation signal may be generated that is output to a speaker or display of the input-output system 50, a key of the vehicle 100, and/or a mobile terminal associated with the vehicle 100, etc. to issue a confirmation request to the driver, such as "whether the vehicle is permitted to be automatically controlled to remove tires from compression?", etc., and after the driver permits, the vehicle control signal is output to the vehicle control system 60 to automatically control the vehicle 100 to remove tires from compression.

The acknowledgement signal may be generated by the generation module 24 as described above, or may be generated by a separate module. The confirming step may be performed before the vehicle control signal is generated.

Therefore, the tire anti-extrusion method can avoid the extrusion of the tire when the vehicle is in a parking state, thereby reducing the damage of the tire and the hidden danger of tire burst caused by the damage.

According to other embodiments of the present invention, after step S60 and before step S80, step S70 is further included. In step S70, it is determined whether the vehicle 100 is about to be parked for a long time. Specifically, in this step S70, it is monitored whether the tire is continuously pressed, and in the case where the tire is continuously pressed for more than a predetermined length of time, it is determined that the vehicle 100 is about to be parked for a long time. Further, in this step S70, it is also possible to detect the distance of the key of the vehicle 100 and/or the mobile terminal associated with the vehicle 100 with respect to the vehicle 100, and determine that the vehicle 100 is about to be parked for a long time when it is detected that the distance exceeds a predetermined distance. Here, the predetermined length of time may be 60s, 80s, etc., and the predetermined distance may be 300m, 400m, etc.

Thus, the tire anti-squeezing method according to the present invention can alert the driver and/or control the vehicle to avoid squeezing of the tire only in the case where the vehicle is about to be parked for a long time, avoid outputting a warning and/or automatically control the vehicle when the vehicle is temporarily stopped during use and the tire abuts against a protrusion of the road surface (for example, while waiting for a red light), and cause trouble to the driver.

Further, according to still other embodiments of the present invention, as shown in fig. 4, after step S60, the process proceeds to step S140, and in step S140, the pressed position of the tire is determined based on the second information. Subsequently, the method proceeds to step S160, in which step S160 a corresponding warning signal and/or vehicle control signal is generated depending on the determined pressed position of the tyre. The method then proceeds to steps S180 and S200, and in step S180, a warning is issued; in step S200, a vehicle control signal is output to the vehicle control system 60 of the vehicle 100 to automatically control the vehicle 100 to perform an operation of releasing the tire from the squeezing. According to some embodiments, before step S200, step S190 may be further included, and in step S190, it is confirmed to the driver whether the automatic control vehicle is allowed to perform the operation of releasing the tire from the squeezing; if the driver permits, the method proceeds to step S200. The confirmation step S190 may be performed before the vehicle control signal is generated.

Furthermore, according to other embodiments, the method may further comprise the step of determining which specific wheel's tyre is squashed based on the first information and the second information, and the step of generating the warning signal and the vehicle control signal accordingly based on such information, facilitating accurate operation of the vehicle.

Further, in the above-described embodiment, the warning signal is transmitted to the speaker or the display of the vehicle 100 to issue a warning therewith. However, according to other embodiments, the warning signal may be transmitted to an output device such as a speaker or a display included in the tire anti-squeezing device 200 to issue a warning using the same. Further, in the above-described embodiment, the warning signal is transmitted to the mobile terminal associated with the vehicle 100 to issue a warning therewith. However, according to other embodiments, the warning signal may be sent to a mobile terminal associated with the tire anti-extrusion device 200 to issue a warning therewith.

Further, in the above-described embodiment, the vehicle control signal is sent to the vehicle control system 60 of the vehicle 100 to automatically control the vehicle 100 with it to perform the operation of releasing the tire from the squeezing. According to other embodiments, the vehicle control signals may not be sent to the vehicle control system 60, but instead directly control the power and drive system, steering system, and braking system of the vehicle 100 to cause the vehicle 100 to perform an operation that removes the tires from compression.
