Abstract
A system for determining abnormalities of a TPMS that includes a pressure sensor that senses a pressure inside a tire and transmits sensed pressure data as a radio signal, a reception unit that receives the radio signal from the pressure sensor and measures strength of the received radio signal, and a determination unit that determines an abnormality of the TPMS based on the radio signal received, and the strength of the radio signal measured, by the reception unit.
Claims13
A system for determining abnormalities of a tire pressure monitoring system (TPMS), the system comprising:
- a pressure sensor that senses a pressure inside a tire and transmits sensed pressure data as a radio signal;
- a reception unit that receives the radio signal from the pressure sensor and measures strength of the received radio signal;
- a determination unit that determines an abnormality of the TPMS based on the radio signal received, and the strength of the radio signal measured, by the reception unit;
- and
- a control unit that controls the pressure sensor to change a data transmission means based on the TPMS abnormality as determined by the determination unit.
A system for determining abnormalities of a tire pressure monitoring system (TPMS), the system comprising:
- a pressure sensor that senses a pressure inside a tire and transmits sensed pressure data as a radio signal;
- a reception unit that receives the radio signal from the pressure sensor and measures strength of the received radio signal;
- and
- a determination unit that determines an abnormality of the TPMS based on the radio signal received, and the strength of the radio signal measured, by the reception unit;
- wherein the reception unit measures strengths of a plurality of additional radio signals for a predetermined second time period at an interval of a predetermined first time period, and
- the system further comprises a volatile memory that stores the strengths of the plurality of additional radio signals measured by the reception unit.
A method of determining abnormalities of a tire pressure monitoring system (TPMS), the method comprising:
- a signal transmission step of converting data of a pressure sensor that measures a pressure of a tire into a radio signal and transmitting the radio signal;
- a reception step of receiving the radio signal of the pressure sensor transmitted in the signal transmission step and measuring a strength of the radio signal;
- a determination step of determining an abnormality of the TPMS based on the radio signal received, and the strength of the radio signal measured, in the reception step;
- and
- a first storage step of storing strengths of a plurality of additional radio signals at an interval of a predetermined first time period in a volatile memory after the reception step.
