Apparatus for automatic adjustment of tire ground area according to driving mode

摘要

An apparatus for automatically adjusting a tire tread area according to a disclosed driving mode is an apparatus for automatically adjusting a tire tread area using a tire pressure monitoring system (TPMS) of a vehicle, the apparatus comprising: a housing positioned inside a wheel; an air injection unit coupled to the housing and exposed to the outside through a hole formed in the wheel; a fixing nut coupled to the air inlet and fixed to the wheel; an air pressure sensor unit coupled to the housing or the air injection unit to measure the pressure inside the tire mounted on the wheel; a circuit unit coupled to the housing and electrically connected to the air injection unit and the air pressure sensor unit; Compressed gas injection unit coupled to the housing; and a control unit capable of driving the air injection unit and the compressed gas injection unit through wireless communication with the circuit unit, wherein the control unit opens the air injection unit according to the driving mode of the vehicle to lower the pressure inside the tire or inject compressed gas from the compressed gas injection unit This can increase the pressure inside the tire, so the tire tread area can be adjusted by adjusting the air pressure inside the tire with the tire air pressure alarm device. You can make this change automatically.
