Description

[0001] The present invention relates to a Bluetooth tire pressure monitoring system suitable for motor vehicles and an operating method therefor.

[0002] Nowadays, many vehicles are equipped with a tire pressure monitoring system (TPMS) to allow the driver to know the condition of the tires in real time and to prevent sudden tire blowouts or insufficient tire pressure, as these can compromise driving safety. A typical TPMS consists of tire pressure sensors attached to the wheel rims and a control unit located inside the vehicle. Each tire pressure sensor reads the air pressure or other preset parameters, such as temperature and humidity, of the corresponding tire within a specific timeframe and then transmits the readings to the control unit. If the reading from a tire pressure sensor is abnormal, the TPMS generates an alarm signal to inform the driver, thus warning them and helping to reduce accidents.

[0003] The most common connection methods used by manufacturers in the tire pressure monitoring system (TPMS) market are wired and wireless antenna connections. These methods increase the cost and weight of the vehicle body. Therefore, a TPMS using a Bluetooth connection has been developed. This method offers advantages in terms of ease of use and installation, lower costs, less impact on vehicle weight, and significantly improves the user experience when connecting to tires. Unlike traditional methods, the tire pressure sensor does not need to be sent back to the factory for data storage. Compared to conventional methods, this system offers improved usability.

[0004] While such methods offer improved usability, the limited range of Bluetooth connections and occasional data loss during transmission sometimes raise concerns about accuracy and efficiency. These problems are particularly common with large multi-wheeled vehicles or vehicles whose tires are located far from the Bluetooth host. Therefore, Bluetooth-connected tire pressure monitoring systems are rarely used in large vehicles.

[0005] Therefore, if the situation described above can be improved, the accuracy and usability of tire pressure monitoring systems connected via Bluetooth can be effectively improved.

[0006] The present invention provides a Bluetooth tire pressure monitoring system comprising a Bluetooth tire pressure sensor, a Bluetooth host, and a Bluetooth auxiliary receiver, wherein the Bluetooth tire pressure sensor comprises a message transmitter module and a capture module, the capture module transmits the captured tire information to the message transmitter module, and the Bluetooth tire pressure sensor performs a Bluetooth synchronization with the Bluetooth host or the Bluetooth auxiliary receiver or both, and transmits the tire information to the Bluetooth host or the Bluetooth auxiliary receiver or both via the message transmitter module.

[0007] Furthermore, the Bluetooth host includes a data transceiver module and a control module, the data transceiver module being used to collect the tire information sent by the Bluetooth tire pressure sensor.

[0008] Furthermore, the Bluetooth auxiliary receiver performs a Bluetooth synchronization with the Bluetooth host, wherein the Bluetooth auxiliary receiver includes a main control module and the main control module serves to collect the tire information sent by the Bluetooth tire pressure sensor and furthermore has the function of transmitting the tire information to the data transceiver module.

[0009] To solve the problem, the present invention further provides an operating method for the Bluetooth tire pressure monitoring system, comprising the following steps: transmission step 1, transmission step 2, analysis backup step, request step, forwarding step and confirmation step.

[0010] In this process, transmission step 1 consists of the Bluetooth auxiliary receiver being switched to device mode (peripheral device) according to the BLE (Bluetooth Low Energy) standard protocol and, after pairing with the Bluetooth host, establishing a Bluetooth pairing and connection with the Bluetooth tire pressure sensor.

[0011] Transmission step 2 consists of the Bluetooth auxiliary receiver switching to host mode according to the BLE (Bluetooth Low Energy) standard protocol after completion of transmission step 1, with the Bluetooth host and the Bluetooth auxiliary receiver synchronously receiving the tire information sent by the Bluetooth tire pressure sensor.

[0012] The analysis backup step consists of the Bluetooth auxiliary receiver storing and backing up the tire information sent by the Bluetooth tire pressure sensor after the completion of transmission step 2. The Bluetooth host checks whether the Bluetooth tire pressure sensor has fully transmitted the tire information, and if the tire information has been fully transmitted, the process proceeds to the confirmation step. If the tire information has been incompletely transmitted, the process proceeds to the prompt step.

[0013] The prompting step consists of the Bluetooth host determining that the tire information received during the analysis backup step is incomplete, instructing the Bluetooth auxiliary receiver to forward the backed-up tire information via the Bluetooth connection.

[0014] The forwarding step consists of the Bluetooth auxiliary receiver receiving the command after the request step is completed and forwarding the secured tire information to the Bluetooth host via the Bluetooth connection.

[0015] The confirmation step consists of the Bluetooth host confirming the tire information for subsequent applications once the tire information received by the Bluetooth host in the analysis backup step is complete, or after the backed-up tire information has been forwarded to the Bluetooth host in the forwarding step. After completion of the confirmation step, the Bluetooth tire pressure monitoring system waits for the start of the next transmission step (step 1).

[0016] To solve this problem, the present invention further provides an additional operating method for the Bluetooth tire pressure monitoring system, comprising the following steps: transmission step 1, transmission step 2, transmission step 3, analysis step, and confirmation step. Transmission step 1 consists of switching the Bluetooth auxiliary receiver into device mode according to the BLE standard protocol and establishing a Bluetooth pairing and connection with the Bluetooth host.

[0017] Transmission step 2 consists of the Bluetooth auxiliary receiver switching to host mode according to the BLE standard protocol after completion of transmission step 1, whereby the Bluetooth host and the Bluetooth auxiliary receiver synchronously establish a Bluetooth connection with the Bluetooth tire pressure sensor in order to obtain the tire information from the Bluetooth tire pressure sensor.

[0018] The third transmission step consists of the Bluetooth auxiliary receiver transmitting the tire information received by the Bluetooth tire pressure sensor to the Bluetooth host via the Bluetooth connection.

[0019] The analysis step consists of the Bluetooth host checking all received tire information after the completion of transmission step 3 and determining whether there are any abnormal activations.

[0020] The confirmation step consists of the Bluetooth host performing a re-confirmation for subsequent applications based on the tire information transmitted in transmission step 3. After completion of the confirmation step, the Bluetooth tire pressure monitoring system waits for the start of the next transmission step 1.

[0021] Therefore, the main object of the present invention is to provide a Bluetooth tire pressure monitoring system and an operating method for it. In conventional Bluetooth tire pressure monitoring systems, an additional Bluetooth auxiliary receiver is provided at a different location than the Bluetooth host, the Bluetooth auxiliary receiver being connected to the Bluetooth host and a Bluetooth tire pressure sensor. The Bluetooth tire pressure sensor transmits the detected tire information to both the Bluetooth host and the Bluetooth auxiliary receiver, and the Bluetooth auxiliary receiver then actively or passively transmits the received tire information to the Bluetooth host. Such multiple verification ensures that the Bluetooth host's data is complete and not easily lost.
