Description

FIELD OF THE DISCLOSURE

The present disclosure provides a tire pressure monitor sensor tire auto-location system and an operating method thereof.

BACKGROUND OF THE DISCLOSURE

With the advancement of technology, to allow drivers to be instantly aware of the condition of car tires to prevent sudden tire blowouts or insufficient tire pressure that affect driving safety, many vehicles are currently equipped with tire pressure detection systems. Common tire pressure detection systems include tire pressure detectors disposed on the rims of vehicles and a host receiver inside the vehicle. Each tire pressure detector reads the pressure of the corresponding tire or other preset parameters such as tire temperature, etc. within a certain period, and then transmits the results to the host.

When it comes to tire pressure detection systems, manufacturers on the market often use a programming method to record the corresponding position and serial number of each tire pressure detector on the host to allow the host to identify the tire pressure detectors on different wheels. This is a robust method to configure the system with sensor serial numbers and their vehicular position.

However, although this method is stable, if the tire pressure detector is required to be replaced or the programmed data is wrong, usually it can only be returned to the factory or dealership and reprogrammed, which is extremely troublesome to the user. Therefore, the tire pressure monitor sensor of the wireless locating system is developed in a configuration that allows the host to wirelessly determine the tire location of each tire pressure monitor sensor and brings convenience for users when it comes to replacing tire pressure detectors.

However, the tire pressure monitor sensors on the market have a problem of high-energy consumption, and poor battery life. To enable the host located in the vehicle to accurately locate the tire pressure monitor sensor, the tire pressure monitor sensors usually continuously transmit location data to the host for a long period of time. Consequently the tire pressure monitor sensors remain in a high-energy consumption state, thereby reducing the service life of the tire pressure monitor sensor.

Therefore, the above problem is required to be optimized and improved. Reducing the energy consumption of tire pressure monitor sensors effectively and increasing battery life, which enables the inclusion of other sensor based functions or the use of smaller lighter batteries. Furthermore, the advantages can increase the consumers' desire to purchase tire pressure monitor sensors with the location function.

The tire auto-location system for a tire pressure monitor sensor includes a host, a plurality of axle rotation detection devices, and a plurality of tire pressure monitor sensors. By allowing the host to receive and compare the corresponding gear ring rotation data transmitted by the plurality of axle rotation detection devices and the corresponding tire rotation data transmitted by the plurality of tire pressure monitor sensors, the location of each tire pressure monitor sensor can be confirmed. At the same time, since the host and the tire pressure monitor sensor have two-way transmission functions, the host can react quickly and promptly command the wireless tire pressure sensor to stop sensing and transmitting after completing the calculation. The system and the operating method significantly reduce the power consumption of the tire pressure monitor sensor.

To achieve the above-mentioned objective and effort, the present disclosure provides a tire auto-location system for a tire pressure monitor sensor.

In order to achieve the above-mentioned objective, the present disclosure provides an operating method of a tire auto-location system for a tire pressure monitor sensor, including establishing a wireless connection step, starting to locate step, first data collection step, second data collection step, calculating step, and end locating step. In which, establishing a wireless connection step refers to: a host connects a plurality of axle rotation detection devices and a plurality of tire pressure monitor sensors correspondingly, and the host establishes a duplex wireless connection with the plurality of tire pressure monitor sensors; wherein the axle rotation detection device continuously transmits the rotation data of a corresponding gear ring to a wired transceiver module of the host through a sensor.

Starting to locate step refers to after completing the establishing a wireless connection step, the wired transceiver module of the host transmits a command to a control module of the plurality of tire pressure monitor sensors to turn on a monitoring module.

First data collection step refers to after completing the starting to locate step, the control module turns on the monitoring module, and the monitoring module transmits a first tire rotation data to the wireless duplex transceiver module of the host through a message module at a first predetermined time or first tire rotation angle, and after receiving the first tire rotation data, the host records and reads a rotation data of the plurality of gear rings and set it as a first axle rotation data.

Second data collection step refers to after completing the first data collection step, the monitoring module transmits a second tire rotation data to the wireless duplex transceiver module of the host at a second predetermined time or second tire rotation angle, and after receiving the second tire rotation data, the host records and reads the rotation data of the plurality of gear rings and set it as a second axle rotation data.

Calculating step refers to after completing the second data collection step, the host receives the first tire rotation data and the second tire rotation data from the plurality of tire pressure monitor sensors, and compares and calculates the first axle rotation data and the second axle rotation data through a processing computing module; so that the host calculates the location of each tire pressure monitor sensor corresponding to each axle rotation detection device, and then locates the position of each tire pressure monitor sensor.

End locating step refers to after completing the calculating step, the host has located the position of each tire pressure monitor sensor, and the host transmits a command of turning off the monitoring module to the control module of the tire pressure monitor sensor through the wireless duplex transceiver module, and then the control module receives the command and turns off the monitoring module.

In practice, before the host determines the location of each tire pressure monitor sensor, the host transmits a command to each tire pressure monitor sensor to turn on the monitoring module, and each tire pressure monitor sensor transmits tire rotation data at two specific times or angles (such as the angle of tire rotation at the first and second times, or the time points of tire rotation at the first and second angles). At the same time, after receiving the above data, the host reads the gear ring rotation data (such as angle or time) of the axle rotation detection device, and compares the above data with each other to calculate which tire pressure monitor sensor corresponds to which axle rotation detection device. Further, due to the tire location of each axle rotation detection device being registered by the host in advance (which can be found in the conventional art), the host can calculate and determine the location of each tire pressure monitor sensor.
