ABSTRACT:
An ABS microcomputer 16 counts the number of pulses given between two counted times and executes a specific processing based on the data of pulse number and pulse counting period. The DWS microcomputer 21 receives the data of pulse number and pulse counting period of the ABS microcomputer 16 through the communication line 17 to calculate the rotational angular velocities of the tires based on the data of pulse number and pulse counting period so that the calculated rotational angular velocities of the four tires are compared with one another to detect whether or not there is a tire reduced in air pressure.
