The indirect tire pressure monitoring device includes: a wheel speed sensor that detects a wheel speed; a reset switch that receives a reset command for recalibrating a reference value of the index for the decompression determination; and a control unit that, when a reset command is received from the reset switch, recalibrates the reference value of the index on the basis of the wheel speed, and when the reset command is received, compares the reference value of the index with a current value to determine whether or not the tire pressure is reduced, and when the tire pressure is reduced, resets the reference value of the index on the basis of the wheel speed. And prohibiting recalibration of the reference value of the index.
间接式胎压监视装置包括:轮速传感器,其检测车轮速度;复位开关,其接收用于对用于减压判定的指标的基准值进行再校准的复位指令;以及控制部,在从复位开关接收到复位指令的情况下,该控制部根据车轮速度对指标的基准值进行再校准,其中,在接收到复位指令的情况下,控制部对比指标的基准值与当前值来判断轮胎气压是否为被减压的状态,在被减压的情况下,禁止对指标的基准值进行再校准。
