Preferably, it is interval that in parking alarm mode 2a, the duration interval of angular velocity measurement is greater than the 5th duration that in parking alarm mode 2a, tire pressure is measured, and preferred, the former is the latter's twice.3 times of interval the 5th duration interval for the alarm mode 2a that advances of duration that parking alarm mode 2a angular velocity measurement adopts.
When tire pressure is brought down below the 3rd preset value, tire pressure monitoring unit also can switch to parking alarm mode 2a from car-parking model 2.For example, the 3rd preset value is 2.4 bar (pressure units), preferably, in the time of can suitably selecting the 3rd preset value to make under tire pressure is down to described the 3rd preset value, need to give inflation of tire.
After measuring through the tire pressure of predefined number of times, enter the alarm mode 1a that advances.Measure number of times and be preferably chosen as the laggard alarm mode 1a that enters to advance at two to five minutes.Accordingly, after measuring through the tire pressure of predefined number of times, also can enter parking alarm mode 2a.For example, number of times and the interval time of duration that can select tire pressure to measure, to enter parking alarm mode 2a after a period of time at 1 to 15 minute.Preferably, when angular motion sensing unit transmission signal shows moving vehicle, also can enter parking alarm mode 2a.
According to an embodiment of the invention, described device for monitoring tyre pressure also comprises memory device, and it can be incorporated in tire pressure administrative unit, stores different preset values in memory device.In memory device, can also store the whether value because causing lower than the 3rd preset value carrying out tire pressure measurement on the preset value having reduced of expression.When each run starts, memory device all can reset.Therefore at parking period, last time, stroke finished to new trip between elementary period, and the switching that enters parking alarm mode 2a lower than the 3rd preset value because of pressure can only occur once.
Being provided with two different parking alarm modes will be highly profitable.The first parking alarm mode is triggered by the pressure rise that exceeds preset value.This parking alarm mode can, for the optimization of inflation additional function, contribute to make tyre inflating to arrive best inflation pressure.The second parking alarm mode is by exceeding the pressure range of decrease of predetermined preset value or being triggered lower than the tire pressure of predetermined value.Preferably, it is interval that the tire pressure of described two kinds of parking alarm modes is measured duration, and/or the number of times that tire pressure is measured is all not identical, after the tire pressure through described number of times is measured, and the parking alarm mode that tire pressure administrative unit will stop being correlated with.
The above; be only the present invention's specific embodiment preferably, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion by the described protection domain with claim.
