<p>PROBLEM TO BE SOLVED: To facilitate an automatic registration of sensor ID.SOLUTION: A sensor unit transmits, at a constant temporal interval, sensor ID, a tire pressure P, a tire temperature and a sensor rotation flag Fsen that is switched in accordance with a rotation speed of a wheel W. When a vehicle travel flag Fecu that is switched in accordance with a vehicle speed is changed (Yes for S11), a wheel ECU extracts the sensor IDs for which sensor rotation flags Fsen have changed within a given period of time T0, from a number of unspecified wireless signals (S12-S19), and stores the extracted sensor IDs as the sensor IDs of the sensor unit of own vehicle (S21), if the number of the extracted sensor IDs is the same as a number of wheels (=4) (Yes for S20).</p> |
