Description
Technical Field
[0001] The invention discloses a method for identifying inner and outer tire pressure detectors, which is applied to vehicles with inner and outer wheels such as trucks and articulated vehicles, so as to facilitate a vehicle host to identify the inner and outer tire pressure detectors. Background Art
[0002] Tire pressure is an important value that determines whether a vehicle can drive safely. With the advancement of technology, the method of detecting tire pressure has also improved a lot. It used to be manually measured wheel by wheel, but now it is automatically measured by various electronic devices and transmitted to the monitoring screen for display. It is much more convenient.
[0003] Among them, the more common electronic devices are tire pressure detectors, which have tire pressure detection related components built in. With the battery-powered electronic module, they can share information online with the matching vehicle host, so that users can view the tire pressure values on the vehicle host. Generally speaking, a conventional vehicle has four wheels, so four tire pressure detectors need to be installed on the left front wheel, right front wheel, left rear wheel, and right rear wheel respectively. However, the aforementioned four tire pressure detectors are exactly the same products, and it is difficult for the vehicle host to identify which of the left front wheel, right front wheel, left rear wheel, and right rear wheel the value of each tire pressure detector is. Therefore, the conventional practice is for the host to receive the rotation direction information and the received wireless signal strength of each tire pressure detector to determine the position of each tire pressure detector.
[0004] However, for vehicles such as trucks and articulated vehicles that have inner and outer wheels, the inner and outer wheels are too close to each other, and the aforementioned method is difficult to identify the inner and outer wheels. Therefore, host identification errors often occur. Therefore, it is necessary for technicians in this field to develop a method to identify the inner and outer tire pressure detectors. Summary of the invention
[0005] The present invention provides a method for the vehicle host to identify the inner and outer wheels by using the tire pressure detector to read and identify the signal strength of the tire pressure detector at the mirror position. Compared with the traditional method, the tire pressure detector of the inner and outer wheels can be identified more accurately.

[0007] Furthermore, the vehicle host has built-in reasonable range values of the total value of the first inner wheel detection signal strength and the total value of the first outer wheel detection signal strength. If the values of the total value of the first inner wheel detection signal strength and the total value of the first outer wheel detection signal strength are not within the reasonable range, the vehicle host re-matches the first inner tire pressure detector, the first outer tire pressure detector, the second inner tire pressure detector, and the second outer tire pressure detector, and restarts the entire round of steps from the signal receiving step until the total value of the first inner wheel detection signal strength and the total value of the first outer wheel detection signal strength are both within the reasonable value range.
[0008] Furthermore, the vehicle host has built-in reasonable range values of the strength of the inner tire pressure detector signal and the outer tire pressure detector signal respectively received by the first outer tire pressure detector and the first inner tire pressure detector. If any of the aforementioned values is not within the reasonable range, the vehicle host re-matches the first inner tire pressure detector, the first outer tire pressure detector, the second inner tire pressure detector, and the second outer tire pressure detector, and restarts the entire round of steps from the signal receiving step until the strength values of the inner tire pressure detector signal and the outer tire pressure detector signal respectively received by the first inner tire pressure detector and the first outer tire pressure detector are all within the reasonable range.

[0012] To understand the implementation of the present invention in more detail, please refer to the accompanying drawings. The method of the present invention is a step following the conventional tire pressure detector judgment step. In the conventional tire pressure detector judgment step, the vehicle host first locks the tire pressure detectors of the left and right wheel groups, and then judges the front and rear wheels and the rotation direction of each tire. Then, multiple tire pressure detectors installed on the left and right wheel groups are derived based on conventional technology. The next step is to identify the inner and outer tire pressure detectors, which is the judgment step provided by the present invention. Figure 1 , Figure 2 The present invention is a method for identifying inner and outer tire pressure detectors, which includes the following steps: a signal receiving step S1: a first wheel set 1 and a second wheel set 2 are arranged in a mirror image, the first wheel set 1 includes a first inner tire pressure detector 11 and a first outer tire pressure detector 12, the second wheel set 2 includes a second inner tire pressure detector 21 and a second outer tire pressure detector 22, the first inner tire pressure detector 11 reads and identifies the signal strength of the second inner tire pressure detector 21 and the second outer tire pressure detector 22, the first outer tire pressure detector 12 reads and identifies the second inner tire pressure detector 21 and the second outer tire pressure detector 22 signal strength; signal strength summing step S2, the first inner tire pressure detector 11 sums the signal strengths of the second inner tire pressure detector 21 and the second outer tire pressure detector 22 read to calculate a first inner wheel detection signal strength total value, the first outer tire pressure detector 12 sums the signal strengths of the second inner tire pressure detector 21 and the second outer tire pressure detector 22 read to calculate a first outer wheel detection signal strength total value; inner and outer wheel identification step S3, the vehicle host 100 receives the first inner wheel detection signal strength total value and the first outer wheel detection signal strength total value and compares them, the larger value is the inner wheel, and the smaller value is the outer wheel.
[0013] The first inner tire pressure detector 11 receives the signals of the second inner tire pressure detector 21 and the second outer tire pressure detector 22 by the first inner wheel signal transceiver module 111, and determines the signal strength thereof. The first inner tire pressure detector 11 can also be used to transmit the total value of the first inner wheel detection signal strength to the vehicle host 100. The first inner tire pressure detector 11 calculates the received signal strengths of the second inner tire pressure detector 21 and the second outer tire pressure detector 22 by the first inner wheel signal summing module 112.
[0014] The first outer tire pressure detector 12 receives the signals of the second inner tire pressure detector 21 and the second outer tire pressure detector 22 by the first outer wheel signal transceiver module 121, and determines the signal strength thereof. The first outer wheel signal transceiver module 121 can also be used to transmit the total value of the first outer wheel detection signal strength to the vehicle host 100. The first outer tire pressure detector 12 calculates the received signal strengths of the second inner tire pressure detector 21 and the second outer tire pressure detector 22 by the first outer wheel signal summing module 122.
[0015] The above content further describes the embodiment of the present invention, and further describes the reason why the vehicle host 100 can identify the inner and outer wheels by comparing the total value of the first inner wheel detection signal strength and the total value of the first outer wheel detection signal strength. Figure 2 In the example presented, the first wheel set 1 is the left wheel and the second wheel set 2 is the right wheel. In the figure, we can see that the first inner tire pressure detector 11 is closer to the second inner tire pressure detector 21 and the second outer tire pressure detector 22 than the first outer tire pressure detector 12. Therefore, the signal strength received by the first inner tire pressure detector 11 will be stronger. In order to facilitate understanding of the implementation of the present invention, the signal strength is indicated by the size of the number. The larger the number, the stronger the signal, and the smaller the number, the weaker the signal. For example, the first inner tire pressure detector 11 receives the second inner tire pressure detector 21 and the second outer tire pressure detector 22. The signal strength of the detector 21 is "7", and the signal strength of the second outer tire pressure detector 22 received by the first inner tire pressure detector 11 is "6", so the total value of the first inner wheel detection signal strength is "13"; and the signal strength of the second inner tire pressure detector 21 received by the first outer tire pressure detector 12 is "6", and the signal strength of the second outer tire pressure detector 22 received by the first outer tire pressure detector 12 is "5", so the total value of the first outer wheel detection signal strength is "11", so after comparing the above two values, the larger one is the inner wheel, and the smaller one is the outer wheel.
[0016] like Figure 2 , Figure 3 The present invention also has a method that does not require a signal strength summing step and only requires a signal receiving step S10 and an inner and outer wheel identification step S20. For example, the signal strength of the second inner tire pressure detector 21 received by the first inner tire pressure detector 11 is "7", and the signal strength of the second outer tire pressure detector 22 received by the first inner tire pressure detector 11 is "6". After the above data is transmitted to the vehicle host 100, the vehicle host 100 can identify that the signal of the second inner tire pressure detector 21 is stronger and therefore the position is the inner wheel, and the signal of the second outer tire pressure detector 22 is weaker. Therefore, the position is the outer wheel; and the signal strength of the second inner tire pressure detector 21 received by the first outer tire pressure detector 12 is "6", and the signal strength of the second outer tire pressure detector 22 received by the first outer tire pressure detector 12 is "5". After the above data are transmitted to the vehicle host 100, the vehicle host can recognize that the signal of the second inner tire pressure detector 21 is stronger, so the position is the inner wheel, and the signal of the second outer tire pressure detector 22 is weaker, so the position is the outer wheel. Subsequently, the vehicle host 100 can confirm the final result after checking the above two sets of comparison results.
[0017] In addition, since the vehicle host 100 will first determine (for example, by using the clockwise or counterclockwise rotation direction to determine) the wheel group to which each tire pressure detector belongs when following the steps of the present invention, for example Figure 5 As shown, this is the case where the vehicle host 100 correctly determines that the first inner tire pressure detector 11 and the first outer tire pressure detector 12 belong to the first wheel set 1, and the second inner tire pressure detector 21 and the second outer tire pressure detector 22 belong to the second wheel set 2. However, in practice, wrong judgments may also occur, for example Figure 6 The presented vehicle host 100 mistakenly judges the first inner tire pressure detector 11 as belonging to the second wheel group 2, and the second inner tire pressure detector 21 mistakenly judges it as belonging to the first wheel group 1, so the present invention further provides a method for error elimination. Taking the first method of the present invention as an example, the vehicle host 100 has a reasonable range of values of the total value of the first inner wheel detection signal strength and the total value of the first outer wheel detection signal strength. If the values of the total value of the first inner wheel detection signal strength and the total value of the first outer wheel detection signal strength are not within the reasonable range, the vehicle host 1 re-matches the first inner tire pressure detector 11, the first outer tire pressure detector 12, the second inner tire pressure detector 21, and the second outer tire pressure detector 22, and restarts the whole round of steps from the signal receiving step S1 until the total value of the first inner wheel detection signal strength and the total value of the first outer wheel detection signal strength are both within a reasonable range. As an example, combined with the description of the present invention in the previous paragraphs and Figure 2 It can be seen from the presented content that when the vehicle host 100 is Figure 5 When the signal presented correctly judges each wheel group, the total value of the feedback signal strength of the first tire pressure detector 11 should be 13. Considering the normal fluctuation of the signal strength, the reasonable range should be 12~14. However, if Figure 6 When an error judgment occurs, the total signal strength value received by the vehicle host will deviate from the aforementioned range. For example, the signal strength 20 read has deviated from the reasonable range of the total signal strength value of the first tire pressure detector 11. Therefore, the vehicle host 100 can determine that there is a signal matching error.
[0018] In order to make the error signal elimination more accurate, the present invention further provides a method, wherein the vehicle host 100 has the first outer tire pressure detector 12 and the first inner tire pressure detector 11 respectively received the inner tire pressure detector signal and the outer tire pressure detector signal strength within a reasonable range. In this method, when the vehicle host 100 receives the total strength value of the first inner wheel signal and the total strength value of the first outer wheel signal, the data used for summing will also be received. If any of the above values is not within a reasonable range If the signal strength of the first inner tire pressure detector 11 and the outer tire pressure detector 12 is within the range of 6.5-7.5, the signal strength from the second inner tire pressure detector 21 should be within the range of 6.5-7.5. If a signal strength outside the range of 6.5-7.5 is received, it can be determined that a signal reception error has occurred.
[0019] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
