Embodiment Construction

[0043] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0044] The wireless tire pressure detection device of the present invention is for installation in a tire of a vehicle, please refer to figure 1 As shown, the wireless tire pressure detection device 100 of the present invention includes an acceleration detection module 10 , a wireless transmission module 20 and a controller 30 .

[0045] The acceleration detection module 10 can be a gravitational acceleration detection module (G-sensor), which includes a circuit board and an acceleration detection integrated circuit (IC) disposed on the circuit board to detect acceleration values ​​in multiple axes. In this preferred embodiment, please refer to figure 2 , the axial direction includes the x-axis and the z-axis of the three-dimensional space coordinates. When the acceleration detection module 10 moves, an x-axis acceleration v...

Abstract

A detection-localizable wireless tire pressure detection device, a system and a location method thereof are disclosed. The method comprises the following steps: receiving a radial acceleration value and a tangential acceleration value of a tire; respectively carrying out calculations between the radial acceleration value and a gravitational acceleration value and between the tangential acceleration value and the gravitational acceleration value so as to respectively obtain a radial vector calculated value and a tangent vector calculated value; judging an operation status according to increases or decreases of the radial vector calculated value and the tangent vector calculated value; judging whether transition of the operation status occurs; and judging location information of the tire according to transition order of operation statuses when transition of the operation status to another operation status is judged.

Description

technical field [0001] The invention relates to a positioning method of a wireless tire pressure detection device, a positionable wireless tire pressure detection device and a positionable wireless tire pressure detection system for judging the position of a tire installed in the wireless tire pressure detection device. Background technique [0002] During vehicle driving, tire pressure is a very important factor for driving safety. If the tire pressure is insufficient, the contact area between the tire skin and the ground will increase, which will increase the friction between the tire and the ground, resulting in increased fuel consumption and increased engine load; in addition, the air temperature inside the tire will also rise, accompanied by air volume expansion. The condition is not good, and in severe cases, there may even be a blowout. Therefore, in order to enable the driver to grasp the tire pressure, so as to slow down the vehicle when the tire pressure is abnorm...
