TIRE PNEUMATIC PRESSURE MONITORING DEVICE AND METHOD MEMORIZING PNEUMATIC PRESSURE DECREASE WARNING FOR INVESTIGATING THE CAUSE OF AN ACCIDENT DUE TO THE TIRE BY MEMORIZING A WARNING OPERATION AND THE STATES THEREOF

摘要

PURPOSE: A tire pneumatic pressure monitoring device and a method memorizing pneumatic pressure drop warning are provided to warn a driver of the pneumatic pressure drop of a tire if pneumatic pressure of the tire is below a constant value and to analyze states about pressure decrease warning later by memorizing pressure-measuring time and pneumatic pressure drop warning time. CONSTITUTION: A tire pneumatic pressure monitoring device for memorizing pneumatic pressure drop warning is composed of a pneumatic sensor(10) for measuring the pneumatic pressure of a tire and outputting a signal corresponding to a measured value; a transmitting unit(20) for converting and sending the signal output from the pneumatic sensor into a wireless signal; a receiving unit(30) for converting and outputting the wireless signal received from the transmitting unit; a first memory(40) for memorizing the position of the tire by the signal output from the receiving unit; a control unit(50) for judging the generation and level of warning by receiving the signal output from the receiving unit and sorting and outputting a correspondent signal stored in the first memory; a warning unit(70) for outputting a warning signal applied from the control unit to the outside; and a second memory(60) for memorizing the warning signal and warning states output to the warning unit.
