The present invention relates to a programming system for a tire pressure monitoring sensor (TPMS), and more particularly, to the programming system that automatically chooses the specific programs of vehicle brands and automatically programs the specific programs to the tire pressure monitoring sensor.
The tire pressure monitoring sensor (TPMS) automatically monitors the tire pressure and reports real-time tire-pressure information to the driver by using either a gauge, a pictogram display, or a simple low-pressure warning light. Generally, the vehicles are equipped with a TPMS when the vehicles are made. Different brands of vehicles develop their specific programs for their TPMS, and only the correct device can access the information of the TPMS.
There are many different after-market programming tools that have a database in which the programs of the tire pressure monitoring sensors of different brands are received. When a user purchases a new TPMS, the correct programs of the specific vehicle brand has to be written into it so as to access the information set by the vehicle makers.
However, the programs of different brands have specific programming steps so that the users have to manually choose the correct programming steps among the different vehicle makes to program the correct programs into the new-purchased TPMS. This takes a lot of time and has low efficiency.
The present invention intends to provide a programming system for automatic programming the correct programs of a specific vehicle brand into the new-purchased TPMS to eliminate the shortcomings mentioned above.
The present invention relates to a programming system for a tire pressure monitoring sensor, and comprises a programming tool and a tire pressure monitoring sensor. The programming tool has a control panel. The programming tool includes a central processor, a program database, a first wireless transmission module and a verification code issuing module built therein. The program database, the first wireless transmission module and the verification code issuing module are electrically connected to the central processor. The central processor is electrically connected to the control panel. The verification code issuing module issues a verification code by the first wireless transmission module. The tire pressure monitoring sensor includes a signal processor which is electrically connected to a program storage module, a verification code receiving module, a feed-back module and a second wireless transmission module. The verification code receiving module includes a pre-set verification code. When the verification code received by the verification code receiving module is equal to the pre-set verification code, the feed-back module issues an installation code to the first wireless transmission module of the programming tool by the second wireless transmission module.
The present invention also provides a method of programming for a tire pressure monitoring sensor. The method comprises the following steps:
step 1: operating a programming tool that is compatible to a tire pressure monitoring sensor;
Step 2: setting the programming tool to an auto programming mode;
step 3: the programming tool issuing a verification code;
step 4: the tire pressure monitoring sensor receiving the verification code, assuming that the verification code received by the tire pressure monitoring sensor is different from a pre-set verification code of the tire pressure monitoring sensor, proceed to a step 5A; assuming that the verification code received by the tire pressure monitoring sensor is equal to the pre-set verification code of the tire pressure monitoring sensor, proceed to a step 5B;
step 5A: assuming that the programming tool issues the verification code and does not receive a feed-back signal for a period of waiting time from the tire pressure monitoring sensor, the programming tool issues another verification code; assuming that the verification code received by the tire pressure monitoring sensor is different from the pre-set verification code of the tire pressure monitoring sensor, proceed to the step 5A; assuming that the verification code received by the tire pressure monitoring sensor is equal to the pre-set verification code of the tire pressure monitoring sensor, proceed to the step, and
step 5B: the tire pressure monitoring sensor issuing an installation code to the programming tool, the programming tool installing a program corresponding to the installation code to the tire pressure monitoring sensor, the step 1 and the step 2 being exchangeable.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
The program database 12 stores programs of the compatible tire pressure monitoring sensor of different models and vehicle brands.
The power supply of the programming tool 1 can be a disposable battery, a rechargeable battery, or an external power supply.
The central processor 12 processes and transfers signals and programs between the electrically connected components.
The signal processor 21 processes signals and programs between the electrically connected components.
As shown in
step 1: operating a programming tool 1 that is compatible to a tire pressure monitoring sensor;
Step 2: setting the programming tool 1 to an auto programming mode;
step 3: the programming tool 1 issuing a verification code by a first wireless transmission module 14 and a verification code issuing module 15;
step 4: the tire pressure monitoring sensor 2 including a verification code receiving module 23 which is cooperated with a second wireless transmission module 25 to receive the verification code, assuming that the verification code received by the tire pressure monitoring sensor 2 is different from a pre-set verification code 231 of the tire pressure monitoring sensor 2, proceed to a step 5A; assuming that the verification code received by the tire pressure monitoring sensor 2 is equal to the pre-set verification code 231 of the tire pressure monitoring sensor 2, proceed to a step 5B;
step 5A: assuming that the programming tool 1 issues the verification code and does not receive a feed-back signal for a period of waiting time (5 seconds, for example) from the tire pressure monitoring sensor 2, the programming tool 1 issues another verification code; assuming that the verification code received by the tire pressure monitoring sensor 2 is different from the pre-set verification code 231 of the tire pressure monitoring sensor 2, proceed to the step 5A; assuming that the verification code received by the tire pressure monitoring sensor 2 is equal to the pre-set verification code 231 of the tire pressure monitoring sensor 2, proceed to the step 5B, and
step 5B: the tire pressure monitoring sensor 2 issuing an installation code by the feed-back module 24 via the second wireless transmission module 25 to the first wireless transmission module 14 of the programming tool 1, the programming tool 1 using the central processor 12 to compare an installation code to the programs in the program database 13 and installing programs corresponding to the installation code to a program storage module 22 of the tire pressure monitoring sensor 2; the step 1 and the step 2 being exchangeable.
Consumers simply purchase after-market tire pressure monitoring sensor from different manufacturers and the after-market tire pressure monitoring sensor are compatible to the programming tool 1, the staff of the repair shop can use the automatic programming mode of the programming tool 1 to quickly install the programs of the corresponding manufacturer to the tire pressure monitoring sensor. For example, the consumer purchases a tire pressure monitoring sensor 2 of model A of brand A, and it is compatible to the list built in the programming tool 1, then the programming tool 1 can automatically program the tire pressure monitoring sensor 2 with the programs of the model A of the brand A by the automatic programming mode.
It is noted that, even if the tire pressure monitoring sensor 2 with the verification code of the model A of the brand A, not only the tire pressure monitoring sensor 2 can program the model A of the brand A, the programming tool 1 can still program other model of other brands manually.
The transmission way of the first wireless transmission module 14 and the second wireless transmission module 25 is Low Frequency (LF), Radio Frequency (RF) or Bluetooth so as to meet the transmission frequency and transmission way of the existed tire pressure monitoring sensors.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
