Description

Tire monitoring system and method

The invention relates to a tire monitoring system and a method thereof for a vehicle vehicle, and more particularly to a tire monitoring system and a method thereof that can accurately determine the correct position of each tire to be tested on the vehicle vehicle.

Generally, in the process of high-speed driving of a vehicle, tire failure is the most difficult sudden traffic accident to prevent immediately. A high proportion of traffic accidents on highways is caused by tire flats. Therefore, being able to monitor tire conditions in advance to effectively prevent tire bursts has become an important development goal in the concept of active safety protection.

Therefore, a tire monitoring system for vehicle tire monitoring is gradually developed and popularized. However, the tire monitoring system uses a transmitter in each tire to transmit tire pressure information to the outside; and a receiver is set on the vehicle carrier to receive After receiving the tire pressure information of each tire and determining each transmitter ID, the correct position of each tire to be tested can be determined. The transmitter transmits the measurement signal to the receiver installed in the driving console of the vehicle by radio frequency, and appropriately displays a warning on the instrument display of the driving console. In conventional systems, the meter display will not show Tire pressure, tire temperature and other values, but only when the tire pressure is too low, too high, gas leakage in the tire, or temperature is too high and other dangerous conditions, the system will automatically alarm, light up a warning light, warn the driver to make corresponding measures in advance Safety protection measures. Therefore, in terms of the current development trend, direct TPMS is now the mainstream. However, the built-in position of each of the aforementioned transmitter IDs must not be changed arbitrarily, otherwise it will cause the user to misjudge the tire position. It is very unfavorable for large trucks that often need tire replacement and replacement.

Especially for the real-time automatic monitoring of the tire pressure when a multi-wheeled vehicle is running, although individual transmitters can alert the driver in advance of dangerous conditions such as tire leaks or insufficient pressure to ensure traffic safety. However, due to the multiple tires being juxtaposed together, the built-in position of each of the aforementioned transmitter IDs can only let the user know whether the front or rear tires are on the side, but cannot accurately determine whether they are outside or inside the side by side. More and more car owners are installing surveillance cameras themselves to effectively confirm the location of punctured or deformed tires, which can effectively improve the vehicle's driving safety.

In addition to the identification of side-by-side tires of multi-wheeled vehicles, whenever a tire is worn on the vehicle and needs to be replaced or the tires at different positions on the same vehicle are replaced, the tire pressure detection systems on the market cannot automatically distinguish That is, the identification code of each tire must be reset into the receiving host. The setting method is usually to first enter the receiving host into the pairing state, and then deflate the tires according to the location indicated by the host, so as to receive the ID identification codes transmitted by the tires at different positions of the vehicle, in order to reset the identification code. . If the user replaces a tire pressure detection device of a different brand (with an unrecognizable ID identification code), it is more likely to fail to match and set.

Therefore, it is necessary to improve the identification of parallel tires of multi-wheeled vehicles in order to overcome the tire identification matching and functional limitations of the current TPMS system, in order to provide vehicle users with more convenient, simple, and highly reliable tire locations. The identification enables the tire monitoring system and its method to be widely used, and effectively improves the traffic safety of users.

For the operation description of the tire monitoring system 100 described above, please also cooperate with the step flow chart of the tire monitoring method S800 of the present invention shown in FIG. 3. The tire monitoring method of the present invention is applied to a head 200 of a vehicle carrier. The vehicle carrier includes a plurality of tires 210 to be tested. The tire monitoring method includes the steps described below.

The plural short-moment positioning triggers 300 are set at the positions corresponding to the tires 210 to be tested. In this embodiment, they are set on the wheel arches. Of course, they can also be set at other positions as needed to achieve the trigger effect. The content disclosed in this embodiment is limited; a trigger signal R1, R2, L1, or L2 corresponding to one of the tires 210 to be tested is transmitted outward through each short-moment positioning trigger 300; and a plurality of transmitters 400 are provided for the corresponding ones to be tested.

In this way, the position of each tire 210 to be tested can be easily confirmed, and it is no longer limited by the built-in fixed position in the past, which effectively solves the problem of identifying parallel tires of multi-wheeled vehicles. In addition, whenever tires on the vehicle are worn and need to be replaced, or tires in different positions on the same vehicle, such as front, back, left, right, etc., the tire pressure detection systems on the market cannot automatically distinguish them, but this embodiment uses short moments. Positioning trigger The device 300 sends out a trigger signal R1, R2, L1 or L2 corresponding to one of the tires 210 to be tested; it can still receive each positioning message 401 through the receiver 500 and comprehensively judge each positioning message 401 in order to locate and judge each tire to be tested The correct position and running status of 210.

Referring to FIG. 2, according to this embodiment, the transmitter 400 in the right front inner wheel and the outer wheel are closest to the short-moment positioning trigger 300 transmitting the trigger signal R1, although the two transmitters 400 may also receive Signals to R2 or L1, L2, but because of the distance, the number of pens received by R1 will be the highest in a period of time. Therefore, after a certain period of time has passed, the two transmitters 400 on the right front can determine the tire 210 to be located on the right front wheel arch through the number of received pens, obtain the position determination U information, and then send a positioning message 401. At this time, the position determination 401 of the positioning message U can confirm that the two transmitters 400 are located on the front right wheel arch, and the rotation direction Y can determine that the transmitter 400 is located on the inside or outside because the rotation direction of the transmitter 400 on the inside and outside wheels is different. , So the rotation direction Y will also be different.

In this embodiment, the receiver 500, the logic operation module 600, and the display device 700 of the tire monitoring system 100 can receive the positioning message 401 sent by each transmitter 400 after completing the position determination U, and then the The identity Z is memorized with the corresponding position. In this embodiment, it is recorded in the logic operation module 600. Of course, it can also be stored in other devices or components as needed. It should not be limited to what is disclosed in this embodiment. .

In this embodiment, the tire monitoring system 100 performs an automatic positioning function each time the vehicle is restarted, so the short-moment positioning trigger 300 will only transmit a trigger signal for a period of time during startup, waiting for each transmission After the transmitter 400 has counted and determined the position and then sends a positioning message 401, the short-moment positioning trigger 300 stops transmitting the trigger signal. Because the logic calculation module 600 has memorized the position of each tire 210 to be tested through the identity recognition Z at this time, the tire pressure X, tire temperature V and other information displayed on the display device 700 will be displayed on the correct wheel position. .

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and retouches without departing from the spirit and scope of the present invention. Therefore, the protection of the present invention The scope shall be determined by the scope of the attached patent application.
