间接式测量汽车胎压,是通过轮速传感器检测轮胎之间转速差,达到检测胎压的目的。当轮胎压力下降时,车轮有效滚动半径变小,会导致轮速变化,这种变化会通过本检测仪检测出来并发出警告。 Indirect measurement of car tire pressure is detected by the wheel speed differential between the tire speed to achieve the purpose of testing tire pressure. When the tire pressure drops, the wheel effective rolling radius becomes smaller, will lead to changes in wheel speed, this change will be detected by the detector and issue a warning.
