[0001] 本發明係有關於一種胎壓監測之方法，特別是一種整合 胎壓監測與免鑰匙進入之方法。 【先前技術·】 [0002] 輪胎壓力（以下簡稱胎壓）不正常時，除了會降低輪胎 壽命及增加車輛燃料消耗外，更會影響車輛剎車性能或 提高爆胎機會。因此，為確保行車安全，胎壓監測系統 (Tire Pressure Monitoring System，簡稱為TPMS ❹ )逐漸被應用，以有效告知使用者胎壓。一般胎壓監測 系統係包含安裝在輪胎部位的胎壓感測單元以及射頻收 發器（合稱胎壓感測模組），還有放置在車内的射頻收 發器以及顯示器。胎壓感測單元測得胎壓數據後，藉由 在輪胎部位的無線（例如射頻）收發器傳送胎壓數據到 放置在車内的無線接收器後，在車輛顯示器上顯示量測 之胎壓數據。 [0003] 免鑰匙進入系統（Keyless; Entry System)目前廣泛地 ◎ 應用在汽車上，藉以取代傳統之實體鑰匙。免鑰匙進入 系統可分為Remote Keyless Entry (簡稱RKE)及 Passive Keyless Entry (簡稱pKE)兩種形式。RKE 系統需使用者按下RKE車用輪起遙控器按紐才能打開車鎖 。PKE系統不需使用者按下PKE車用鑰匙遙控器按鈕，只 要PKE車用鑰匙遙控器靠近車輛，車門即自行開鎖。在上 述兩種免錄匙進入系統中，車用鎗匙遙控器都有無線發 射器，車内也安裝相對應之無線接收器。 099106245 表單編號A0101 0992011323-0 201130673 [0004]上述胎壓監測系統及免鑰匙進入系統在習知技術中是屬 於各自獨立作業之系統，彼此並不互動或是共用零件。 - 也就是說’汽車内必須有一套無線接收器及相關元件用 來對應胳屢監測系統，而又需要另一套無線接收器及相 關疋件用來對應免鑰匙進入系統。然而，胎壓監測系統 及RKE免鑰匙進入系統卻是使用相同的頻率進行資料的傳 輸°因此’使用各自的無線收發器及相關部件將造成硬 體重複及成本浪費。 Ο [0005]再者’―般之胎壓感測系統之胎壓感測模組，由於位在 輪胎之内，所以大多藉由電池作為電力，該胎壓感測模 組之輪胎資訊信號發送週期，亦即兩次輪胎資訊信號發 送間隔之時間不能太短，以避免電力之損耗，因此使用 者—般而言無法立即知道胎壓數據。然而，為了提供更 局之安全規格，胎壓感測模組最好能在使用者需用車之 時立即提供胎壓數據，以提高安全效果。 【發明内容】 〇 [㈤06]本發明之一目的在#提供一種可即時提供胎壓數據之整 合胎壓監測與遠端免鑰匙進入之系統與方法。 [0007] 本發明之另一目的在於提供一種可兼顧胎壓數據即時性 及可節電之整合胎壓監測與遠端免鑰匙進入之系統與方 法。 [0008]

method of integrating tire pressure monitoring and keyless entry. [Prior Art·] [0002] When the tire pressure (hereinafter referred to as tire pressure) is abnormal, it will affect the brake performance of the vehicle or increase the chance of puncture, in addition to reducing the life of the tire and increasing the fuel consumption of the vehicle. Therefore, in order to ensure driving safety, the Tire Pressure Monitoring System (TPMS ❹) is gradually being applied to effectively inform the user of the tire pressure. The general tire pressure monitoring system consists of a tire pressure sensing unit mounted on the tire and an RF transceiver (collectively called a tire pressure sensing module), as well as an RF transceiver and display placed in the vehicle. After the tire pressure sensing unit measures the tire pressure data, the measured tire pressure data is displayed on the vehicle display by transmitting the tire pressure data to the wireless receiver placed in the vehicle at a wireless (eg, radio frequency) transceiver at the tire site. . [0003] The Keyless; Entry System is currently widely used in automobiles to replace traditional physical keys. The keyless entry system can be divided into Remote Keyless Entry (RKE) and Passive Keyless Entry (pKE). The RKE system requires the user to press the RKE car wheel remote control button to unlock the car. The PKE system does not require the user to press the PKE vehicle key remote control button. As long as the PKE vehicle key remote control is close to the vehicle, the door is unlocked by itself. In the above two types of keyless entry systems, the vehicle's key remote control has a wireless transmitter, and a corresponding wireless receiver is also installed in the vehicle. 099106245 Form No. A0101 0992011323-0 201130673 [0004] The above-described tire pressure monitoring system and the keyless entry system are separate systems in the prior art, and do not interact with each other or share parts. - That is to say, there must be a set of wireless receivers and related components in the car to correspond to the monitoring system, and another set of wireless receivers and related components are required to correspond to the keyless entry system. However, the tire pressure monitoring system and the RKE keyless entry system use the same frequency for data transmission. Therefore, using the respective wireless transceivers and related components will cause hardware duplication and cost waste. Ο [0005] In addition, the tire pressure sensing module of the tire pressure sensing system is mostly located in the tire, so most of the tires are used as electric power, and the tire pressure sensing module transmits the tire information signal. The period, that is, the interval between two tire information signal transmission intervals should not be too short to avoid power loss, so the user cannot know the tire pressure data immediately. However, in order to provide a more secure specification, the tire pressure sensing module preferably provides tire pressure data immediately when the user needs to use the vehicle to improve safety. SUMMARY OF THE INVENTION [(5) 06] One object of the present invention is to provide a system and method for integrating tire pressure monitoring and remote keyless entry that can provide tire pressure data on the fly. Another object of the present invention is to provide a system and method for integrating tire pressure data and power saving integrated tire pressure monitoring and remote keyless entry. In order to achieve the above object of the present invention, an integrated tire pressure monitoring and keyless system of the present invention includes an integrated controller and at least one tire pressure sensing module. The integrated controller is located within the vehicle and includes a central control unit and a central wireless transceiver unit. The tire pressure sensing module is located in the vehicle tire 099106245 Form No. A0101 Page 5 / Total ι8 page 〇 99 201130673 and includes a tire pressure processing unit, a tire pressure wireless transceiver unit and a tire pressure sensing unit, wherein the tire pressure sensing unit The pressure processing unit is electrically connected to the tire pressure wireless transceiver unit and the tire pressure sensing unit, and the tire wireless transceiver unit operates with the signal of the predetermined carrier frequency. After receiving the unlock signal of the vehicle key remote controller and confirming the identity verification code of the unlock signal, the integrated controller sends a tire information request signal to the tire pressure sensing module, and the tire pressure sensing module The group sends a tire information signal containing at least tire pressure data for a predetermined period of time. [0009] In order to achieve the above object of the present invention, the integrated tire pressure monitoring and hands-free system method of the present invention comprises: [0010] (a) detecting an unlocking signal from a vehicle key remote controller when the vehicle is in a locked state [0011] (b) transmitting the tire information request signal to the tire pressure sensing module if the identity authentication code from the unlocking signal of the vehicle key remote controller is confirmed; and [0012] (c) the tire pressure sensing module A tire information signal is transmitted for a predetermined period of time, and the tire information signal is transmitted at the predetermined carrier frequency and includes at least tire pressure data. [0013] With the above system and method, only one radio frequency transceiver unit in the vehicle can correspond to the tire pressure monitoring system and the keyless entry system, thereby greatly saving manufacturing costs. The tire pressure sensing module transmits tire pressure data within a certain period of unlocking (for example, within 6 seconds) to achieve higher safety specifications. [Embodiment] [0014] Please refer to the first figure, which is a schematic diagram illustrating the application of the integrated tire pressure monitoring and vehicle remote unlocking system of the present invention. Integrated tire pressure monitoring of the present invention 099106245 Form No. A0101 Page 6 of 18 0992011323-0 201130673 ◎ [0015] The remote control unlocking system for vehicles and vehicles is applied to a vehicle and includes an integrated controller located in the vehicle. 10 and at least one tire pressure sensing module 20 (four shown). The vehicle has a vehicle key remote controller 3搭配, and the integrated controller 1〇 and the tire pressure sensing module 2 〇 and the car key remote control 3〇 can communicate with each other wirelessly. In more detail, the integrated controller 10, the tire pressure sensing module 20, and the vehicle key remote controller 30 are connected to each other by a wireless signal of a predetermined high frequency carrier frequency, which may be, for example, 433. 92MHz or 315MHz, but can also be other ranges of frequencies. Please refer to the second figure, which is a block diagram illustrating the integrated tire building monitoring and vehicle remote unlocking system of the present invention. The integrated controller 1 includes a central control unit 100, a central wireless receiving unit 110a, a central wireless transmitting unit 110b, and an antenna 120; wherein the central wireless receiving unit 110a and the central wireless transmitting unit The central control unit is electrically connected to the central control unit and can be integrated into a central wireless transceiver unit 11 through which the central wireless transceiver unit 110 can receive unlocking/locking from the vehicle key remote controller 30. The command signal and the tire pressure sensing module 20 achieve two-way communication with each other by wireless signals. After the program is programmed, the central control unit 100 can interpret the unlock/lock command signal from the vehicle key remote controller 30 and send a command signal for controlling the tire pressure sensing module 20. The vehicle key remote controller 30 has a remote control unit 300, a remote radio transmitting unit 310, an antenna (not shown), and a plurality of buttons (not shown). The user can initiate a wireless command signal for controlling the unlocking/locking of the door by pressing a button on the key remote control 30 of the vehicle, and the unlocking/locking command signal has an ID code. The central 099106245 Form No. A0101 Page 7 / 18 pages 0992011323-0 201130673 After the control unit 100 receives the unlock/lock command signal via the antenna 114 and the central wireless transceiver unit 110, if the identity identification in the command is confirmed The code matches the built-in identity code of the vehicle, that is, the door lock (not shown) is controlled to unlock and lock the door. [0016] The tire pressure sensing module 20 includes a tire pressure processing unit 200, a tire pressure wireless receiving unit 21 0 a, a tire pressure wireless transmitting unit 21 0 b and a tire pressure antenna (not shown), wherein The tire pressure wireless receiving unit 210a and the tire air wireless transmitting unit 210b can wirelessly transmit signals f to the central wireless transmitting unit 110b and the central wireless receiving unit 110a of the integrated controller 10, and can be integrated into a tire pressure wireless transceiver unit 210. . The tire pressure sensing module 20 further includes a tire pressure sensing unit 220 and a power source (for example, a battery) 230, wherein the power source 230 supplies power of other components in the tire pressure sensing module 20. The tire pressure sensing unit 220 is electrically connected to the tire pressure processing unit 200 to transmit the measured tire pressure data to the tire pressure processing unit 200. The tire pressure processing unit 200 can process the tire pressure sensing unit 220 to measure the data and convert it into a signal transmitted by the tire air frequency transmitting and receiving unit 210. This portion is a prior art and therefore will not be described again. In addition, the tire pressure processing unit 200 can receive a control command from the central control unit 100 (received by the tire pressure wireless transceiver unit 210) to control the tire information signal transmission period (described later). In addition, the tire pressure sensing module 20 may further include other sensing units, such as a temperature sensing unit (not shown) or a power sensing unit (not shown) to sense the temperature inside the tire and the battery power 〇 [ 0017] The tire pressure sensing module 20 emits a tire information signal to the integrated control 099106245 when the vehicle is not in use (for example, when not ignited) to the integrated control 099106245 Form No. 8 / 18 pages 0992011323 -0 201130673 Ο [0018] The device 10, wherein the tire information signal includes at least one of a tire pressure, a tire temperature, and electrical ground power data. When receiving the round request signal sent by the integrated controller H), the tire housing sensing module 2Q immediately sends a secret information signal to the integrated control for a predetermined period of time (sand 6 seconds). The tire information signal is transmitted by a high frequency carrier (3) such as 433·92ΜΗζ or 3). According to the present invention, the tire information data includes at least _ tire pressure data. The sensing module is only used when the vehicle is in use (for example, after ignition), and the tire information information is transmitted in a short operation cycle. The integrated tire type (four) (4), the tire weight reduction number includes at least the rotation and the wheel sound level data. 。[0019] Referring to the third figure, the flow chart of the operation of the integrated tire pressure monitoring and vehicle remote unlocking system of the present invention is illustrated. In the step, the wheel train is in-locked. Then in step _Q2, The integration is interesting to say that after receiving the unlock command signal from the remote key controller of the vehicle and determining that the identity identification code of the unlock command signal matches (siiQ), the lock operation is performed (S112). - Tire information request letter red secret pressure defeat _ to request the tire The sensing module 20 immediately ships the tire (4) (SU4), and the line tire pressure _ module 2 〇 will be in the - predetermined hiding (for example, 6 seconds), the wheel information (the tire tire information contains at least - tire pressure data) The tire information signal is transmitted to the integrated controller 10, and the wire is present on the integrated control (4) of the vehicle. The integrated control then determines the engine ignition of the vehicle (S120), and the integrated control (four) transmission-cycle Switching signal to the tire pressure sense 099106245 Form No. A0101 Page 9 / Total page 0992011323-0 201130673 [0020] [0022] 099106245 Module 2G α switch tire pressure sense _ group 2 () send tire information signal Cycle (S122) 〇 See the fourth diagram 'Sche diagram of the tire information signal cycle for training. Before the engine is ignited', the tire pressure sensing module is sent to the tire with a long standby period (standby peri〇d) Ps Information signal. After the door is unlocked, the integrated control (4) sends a round-robin request signal to the tire pressure sensor group 2G', then the tire group 20 immediately transmits at least the tire information-tire information signal (see The fourth picture plus the letter of the slash No.) to the integrated controller 1〇 to immediately inform the integrated controller 10 tire pressure series. After the ignition, the return sensing module (4) with a shorter operating cycle (0perati〇n peri〇d) p. Send a tire information signal, where PS>PG. Therefore, after the vehicle is ignited, the user can immediately know the latest data of the tire pressure (sent in the cycle p). In the case of the vehicle, the secret data of the money is reduced (sent by the longer period Ps), and the tire battery power can be solved. After the vehicle is ignited, if the integrated controller 1 determines the engine total fire (S13G) of the vehicle, the integrated control switch sends a cycle switching signal to the tire pressure sensing module 2G to switch the tire pressure. The period in which the sensing module 2 () transmits the tire information signal (S132). More specifically, the tire pressure sensing module 2 切换 switches the cycle of transmitting the tire information signal to a longer standby period k ′ to save power. If the integrated controller 10 receives a lock command signal from the vehicle key remote controller (S140), the situation indicates that the owner should leave the vehicle and the vehicle is no longer in a running state, so the integrated controller 1〇 The operation state will be restored to the initial upper lock state (step sl1), and the form number A0101 will be continued.
