Fig. 1 is a schematic view showing the configuration of a tire pressure monitoring device according to an exemplary embodiment of the present invention.
The tire pressure monitoring apparatus 100 according to the present invention may be implemented inside a vehicle. In this case, the tire pressure monitoring device 100 may be integrally formed with an internal control device of the vehicle, or may be connected to the control device of the vehicle through a separate connector after being implemented as a separate device. As an example, the tire pressure monitoring device 100 may be implemented as a Tire Pressure Monitoring System (TPMS).
Referring to fig. 1, a tire pressure monitoring device 100 may include a controller 110, a sensor 120, an output device 130, a communicator 140, and a storage device 150. In the present exemplary embodiment, the controller 110 of the tire pressure monitoring apparatus 100 according to the present embodiment may be implemented as at least one processor. The controller 110 may process signals sent to each component of the tire pressure monitoring device 100.
The vehicle is provided with tires arranged on a left front side FL, a right front side FR, a left rear side RL, and a right rear side RR, respectively. The sensor 120 may detect a tire pressure of any one of four tires provided to the vehicle. In this case, the sensor 120 may be arranged on the wheel side connected to any one of the four tires.
The arrangement of the sensor 120 is with reference to the embodiment of fig. 2. In the following embodiments, the sensor 120 is disposed on the wheel side of the front left side FL, however, it should not be limited thereto or thereby.
The sensor 120 can detect the tire pressure of the tire 11 disposed on the front left side FL among the four tires 11 to 14. In this case, the sensor 120 may detect the tire pressure of the tire 11 in real time, and may transmit the detected tire pressure to the controller 110.
Meanwhile, when detecting that the tire pressure is equal to or less than the reference value, the sensor 120 may transmit the tire pressure detection information of the tire 11 to the controller 110. As an example, when detecting that the tire pressure is equal to or less than about 26.4psi, the sensor 120 may transmit tire pressure detection information of the tire 11 to the controller 110.
When air is injected into the four tires 11 to 14 in the parking state of the vehicle, the sensor 120 may detect the tire pressure of the tire 11 before the air is injected into the tire 11 provided on the front left side FL, and the tire pressure of the tire 11 after the air is injected into the tire 11 provided on the front left side FL.
In this case, the sensor 120 may detect the tire pressure of the tire 11 in real time, and may transmit the tire pressure detection information of the tire 11 to the controller 110 when a tire pressure change of a predetermined amount or more is detected.
Output device 130 may include one or more output devices for outputting the operating state and operating results of tire pressure monitoring device 100.
As an example, the output device 130 may include a display for displaying the tire pressure status and/or a message according to the tire pressure status. In addition, the output device 130 may further include an instrument panel for illuminating a warning lamp according to the tire pressure state. In addition, the output device 130 may further include a speaker or a buzzer that outputs a warning sound according to the tire pressure state.
The display may include at least one of a Liquid Crystal Display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an Organic Light Emitting Diode (OLED), a flexible display, a Field Emission Display (FED), or a three-dimensional (3D) display.
The communicator 140 may include a communication module supporting a communication interface with electronic devices and/or control apparatuses included in the vehicle. For example, the communicator 140 may include a communication module that supports signal transmission and reception between sensors and/or control devices included in the vehicle. In an embodiment, the communication module may be a module supporting vehicle network communication, such as Controller Area Network (CAN) communication, local Interconnect Network (LIN) communication, and Flex-ray communication.
In addition, the communicator 140 may further include a module for wireless internet access and/or a communication module for short-range communication.
The memory device 150 may store data and/or algorithms required to operate the tire pressure monitoring device 100.
As an example, memory device 150 may store tire pressure information and/or information of tire pressure changes detected by sensor 120. In addition, the storage device 150 may store the permission or non-permission setting information of the tire pressure setting button based on the information of the tire pressure variation. Further, the storage device 150 may store an instruction for notifying a corresponding message according to the permission or non-permission setting state of the tire pressure setting button.
In this embodiment, the storage device 150 may include a storage medium such as a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a Read Only Memory (ROM), a Programmable Read Only Memory (PROM), or an Electrically Erasable Programmable Read Only Memory (EEPROM).
When the sensor 120 detects that the tire pressure is equal to or less than the reference value, the controller 110 may warn that the tire pressure is low through the output device 130. As an example, the controller 110 may turn on a low tire pressure warning light of the instrument panel. In addition, the controller 110 may display a low tire pressure warning message on a display screen or may output a warning sound through an alarm.
After warning the state of low tire pressure, when a tire pressure change of a predetermined amount or more is detected in a stopped state of the vehicle, the controller 110 sets the tire pressure setting button to a permission state. Meanwhile, after detecting that the tire pressure is equal to or less than the reference value, when a tire pressure change of a predetermined amount or more is not detected in a stopped state of the vehicle, the controller 110 sets the tire pressure setting button to an unauthorized state.
The tire pressure setting button may be installed in a vehicle. Accordingly, when the tire pressure is reset after warning of low tire pressure, the user (or driver) can operate the tire pressure setting button.
When the user (or driver) operates the tire pressure setting button, the controller 110 recognizes whether the tire pressure setting button is in a permission setting state or an unauthorized setting state.
When the tire pressure setting button is in the permission state, the controller 110 learns the tire pressure according to the operation of the tire pressure setting button and stores the learning result of the tire pressure. In this case, the controller 110 may notify the user (or driver) that the tire pressure is stored.
An embodiment related to the above is described with reference to fig. 3A and 3B.
Referring to fig. 3A, in the parking state of the vehicle, the sensor 120 can detect a state where the tire pressure increases from about 25psi to about 33psi due to the injection of air into the tire 11 disposed at the front left side FL. In this case, the sensor 120 may detect the tire pressure variation information of the tire 11, and may transmit the tire pressure variation information of the tire 11 to the controller 110.
Therefore, the controller 110 sets the tire pressure setting button 21 to the permission state based on the tire pressure variation information of the tire 11 detected by the sensor 120.
When the user (or driver) operates the tire pressure setting button 21 in a state where the tire pressure setting button 21 is set to the permission state, the controller 110 may store the current tire pressure and may notify that the tire pressure is stored through the display screen as shown in fig. 3B.
Meanwhile, when the tire pressure setting button 21 is operated in a state where the tire pressure setting button 21 is in an unauthorized state, the controller 110 may notify the user (or the driver) to re-operate the tire pressure setting button 21 after recognizing the tire pressures of the four tires.
Embodiments related to the above are described with reference to fig. 4A and 4B.
Referring to fig. 4A, in the parking state of the vehicle, the sensor 120 can detect that the tire pressure of the tire 11 disposed on the front left side FL is about 25psi. In this case, since the tire pressure of the tire 11 is not changed, the sensor 120 may not transmit the tire pressure change information of the tire 11 to the controller 110.
Accordingly, since the tire pressure variation information of the tire 11 is not received from the sensor 120, the controller 110 sets the tire pressure setting button 21 to the unauthorized state.
When the user (or driver) operates the tire pressure setting button 21 in a state where the tire pressure setting button 21 is set to the unauthorized state, the controller 110 prevents the learning and storage of the current tire pressure. As shown in fig. 4B, the controller 110 may alert that the tire pressure of four tires needs to be identified since the low pressure condition of the tires is maintained.
As described above, the tire pressure monitoring device 100 according to the present invention can prevent the tire pressure from being incorrectly stored when the user (or driver) incorrectly operates the tire pressure setting button 21.
The tire pressure monitoring apparatus 100 according to the present embodiment operating as described above may be implemented in one independent hardware including a memory and a processor that process each operation, and may be driven when included in other hardware (e.g., a microprocessor or a general-purpose computer system).
Hereinafter, the operation of the tire pressure monitoring device 100 having the above-described configuration according to the present invention will be described in detail.
Fig. 5 and 6 are flowcharts illustrating operations of a tire pressure monitoring method according to an exemplary embodiment of the present invention.
Fig. 5 illustrates an operation of setting a permission or non-permission state of the tire pressure setting button according to a tire pressure variation.
Referring to fig. 5, when the sensor 120 detects a low pressure state of the tire (S100), the tire pressure monitoring device 100 warns of the low pressure state of the tire (S110).
Then, the tire pressure monitoring device 100 recognizes whether the vehicle is in a stopped state through the sensor 120 (S120). When it is recognized that the vehicle is in a stopped state in step S120, the tire pressure monitoring device 100 recognizes whether a tire pressure change of a predetermined amount or more is detected (S130).
When the sensor 120 detects a tire pressure change of a predetermined amount or more in step S130, the tire pressure monitoring device 100 determines that air is injected into the tire, and SETs a tire pressure setting button (SET button) to an allowable state to store the changed tire pressure (S140).
Meanwhile, when the sensor 120 does not detect a tire pressure change of a predetermined amount or more in step S130, the tire pressure monitoring device 100 determines that air is not injected into the tire and SETs a tire pressure setting button (SET button) to an unauthorized state to prevent the tire pressure in a low pressure state from being stored (S150).
In this case, when air is not injected into the tire, the tire pressure setting button (SET button) is continuously maintained in an unauthorized state.
Fig. 6 shows an operation of storing tire pressure and notifying the tire pressure storage by the operation of the tire pressure setting button.
When a tire pressure setting button (SET button) signal is input by a user (or driver) operating the tire pressure setting button (SET button) after the tire pressure setting button (SET button) is SET to a permitted or an unauthorized state through the process of fig. 5 (S210), the tire pressure monitoring device 100 identifies whether the tire pressure setting button (SET button) is in a permitted or an unauthorized state (S220).
When recognizing that the tire pressure setting button (SET button) is in the permission state in step S220, the tire pressure monitoring device 100 learns and stores the current tire pressure (S230), and notifies the completion of the state of the tire pressure storage (S240).
When it is recognized that the tire pressure setting button (SET button) is in an unauthorized state in step S220, the tire pressure monitoring device 100 prevents the learning and storage of the tire pressure and notifies that the tire pressure needs to be recognized (S250).
Fig. 7 is a block diagram illustrating a configuration of a computing system that executes a method according to an exemplary embodiment of the present invention.
Referring to fig. 7, the computing system 1000 may include at least one processor 1100, a memory 1300, a user interface input device 1400, a user interface output device 1500, a storage device 1600, and a network interface 1700, which are connected to each other via a bus 1200.
Processor 1100 may be a Central Processing Unit (CPU) or semiconductor device that processes instructions stored in memory 1300 and/or storage 1600. Memory 1300 and storage 1600 may include various types of volatile or non-volatile storage media. For example, the memory 1300 may include a ROM (read only memory) 1310 and a RAM (random access memory) 1320.
Thus, the operations of a method or algorithm described in connection with the embodiments disclosed herein may be embodied directly in a hardware module or a software module executed by the processor 1100, or in a combination of the two. A software module may reside on a storage medium (i.e., memory 1300 and/or storage 1600) such as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, a hard disk, a removable disk, and a CD-ROM. An exemplary storage medium can be coupled to the processor 1100, and the processor 1100 can read information from, and record information in, the storage medium. In the alternative, the storage medium may be integral to the processor 1100. Processor 1100 and the storage medium may reside in an Application Specific Integrated Circuit (ASIC). The ASIC may reside in a user terminal. In another case, the processor 1100 and the storage medium may reside as separate components in a user terminal.
According to the present invention, stability and reliability can be improved by determining whether or not to permit the setting of the tire pressure setting button according to the state of change of the tire pressure, and by preventing the erroneous tire pressure from being learned when the tire pressure setting button is incorrectly operated.
In addition, according to the present invention, by detecting a change in tire pressure using one tire pressure sensor, it is possible to accurately determine a change in tire pressure at low cost.
Although the present invention has been described above with reference to the exemplary embodiments and the accompanying drawings, the present invention is not limited thereto, and those skilled in the art to which the present invention pertains may make various modifications and changes in various ways without departing from the spirit and scope of the present invention as claimed in the appended claims.
