TOUCH-CONTROL TIRE PRESSJRF. SEN. SOR DEVICE AND ITS
SETTING METHOD
BACKGROUND OF THE INVENTION
1.. Field of the Invention
Ihe present invention relates to tire pressure monitoring technology and more particularly, to a touch-control tire pressure sensor device.
2. Description of the Related Art
A tire pressure sensor device generally provide a re-learning mode for enabling an on-vehicle main, unit to memorize the identification code of each of the four wheels of the vehicle carrying the on-vehicle nmin unit. Subject to the respective identification codes, the on-vehicle main unit can recognize the data of each of the four whcels and display the temperature, tire pressure and other related data of the respective wheel. If a wheel tire abnormality occurs, the on-vehicle main unit can give a warning message indicative of the abnormality of the respective wheel tire. After installation of a commercial tire sensor in a vehicle tire, a re-learning mode is initiated.
The re-learning mode includes two types, namely, the on-travel automatic re-learning mode and the still type manual re-learning mode. If the still type manual re-learning mode is employed, the procedure is to let the on-vehicle main unit enter the re-learning mode, and then to enable the tire sensors of the four theels output a respective wireless signal. to the on-vehicle main unit subject to a predetermined sequence, for example, the sequence of left front-÷right front-*right rear-*left rear. Thus, the on-vehicle main unit can memorize the identification codes of the four wheels.
Currently, enabling the tire pressure sensor of a vehicle tire to output a wireless signal can be done by means of using a magnet, using a low frequency setting tool., or discharging the tire presstire However, because a magnet or low frequency setting tool is not readily available, it is not so simple to enable the tire pressure sensor of a vehicle tire to output a wireless signal by using a magnet or low frequency setting tool.
Enabling the tire pressure sensor of a vehicle tire to output a wireless signal by discharging the tire pressure is quite simple, however, the user must inflate the fire to S the original standard value after the re-learning mode. The operation procedure of this re-learning mode is troublesome.
