Description

Setting method of Bluetooth tire pressure monitoring system

The invention relates to a tire pressure monitoring system, in particular to a method for setting a Bluetooth tire pressure monitoring system.

At present, the most common method for pairing the tire pressure sensor ID position with the tire position is to make the receiving host on the vehicle enter the learning mode, and then according to the order of the tire position required by the learning mode, such as left front, right front, left rear, The right rear sequence sequentially triggers the tire pressure sensor at the corresponding position one by one, so that the tire pressure sensor at the corresponding position can send a signal and is received by the host, and the host receives the tire pressure at the corresponding position. After the ID signal sent by the sensor, the tire position is paired with the corresponding ID and stored, so that the host can use the different ID to make the video signal from the tire pressure sensor at that position. You can also display this information correctly on the display device on the car to provide the driver. But from another point of view, because the information is displayed on the vehicle, the driver must start the vehicle to see the information, and the state of the vehicle tire cannot be known until the driver has started the vehicle.

Although it was later proposed that the function of receiving and displaying information was moved from the host and display on the vehicle to a handheld device, such as a smart phone or tablet, even in this case, the tire position was paired with the tire pressure sensor ID. The setting mode is still the same, this is not an ideal operating mode.

In view of the above, an object of the present invention is to provide a method for setting a Bluetooth tire pressure monitoring system, which can quickly and easily perform a pairing operation between a tire position and a tire pressure sensor ID to complete tire pressure monitoring. System settings.

In order to achieve the above object, a Bluetooth tire pressure monitoring system is provided by setting an application program installed in a handheld device, and displaying a tire position in the display device from the application device. Selecting an option box for setting the position of the tire, the application sends a request signal to the tire pressure sensor through a Bluetooth transmission interface of the handheld device, and the tire pressure sensor receives the request signal from a Bluetooth transmission interface A reply signal will be sent back. The reply signal contains the ID code of the tire pressure sensor itself. The handheld device will set the ID of the tire pressure sensor after receiving the reply signal from the tire pressure sensor. Listed in the option box of the tire position, a selected ID is selected by the ID listed in the tire position option box, and then the storage is confirmed, and the selected ID represents the tire pressure sensor corresponding to the position.
