In the most same or similar label represent same or similar element or there is same or like merit
The element of energy.The embodiment described below with reference to accompanying drawing is exemplary, is only used for explaining this
Bright, and be not construed as limiting the claims.
As it is shown in figure 1, the tire pressure monitoring method of the present invention comprises the steps:
Step S1: after receiving enabling signal, obtains the cumulative number that tire pressure monitoring sensor lost efficacy,
Perform step S2 afterwards.This enabling signal is usually power on signal, i.e. runs tire pressure monitoring side of the present invention
The car body controller of method the most first obtains the cumulative number that tire pressure monitoring sensor lost efficacy, here,
This enabling signal can also add other entry conditions according to demand.
Step S2: judge that cumulative number whether more than default value, the most then performs step S3, as no
Then perform step S5 and step S4.
Step S3: export Failure Alarm to the warning device of tire pressure monitoring sensor and enable signal until connecing
Till receiving the tire pressure that tire pressure monitoring sensor sends, so that warning device is receiving inefficacy report
Carry out tire pressure monitoring sensor Failure Alarm during alert enable signal, and after receiving tire pressure, hold
Row step S4 and reset by cumulative number and latch, the implication of latch does not allow during being latch tired
Metering number is modified.
Step S4: during speed is more than preset vehicle speed limit value, does not connects if continuing the first Preset Time
Receive tire pressure, then reporting to the police to warning device Out-Lost enables signal until receiving tire pressure
Till, lose so that warning device carries out tire pressure monitoring sensor when receiving loss alarm and enabling signal
Lose and report to the police.Here, obtain in the speed information that can be sent by vehicle speed sensor of this speed, this is first pre-
If the time is less than or equal to 10 minutes according to relevant regulatory requirements, if this first Preset Time sets
The too small tire pressure monitoring sensor loss alarm that will frequently carry out, the usually false alarm and this kind is reported to the police,
Affect tire pressure monitoring car load run, to this end, this first Preset Time be usually arranged as more than or etc.
In 8 minutes, it is set to 8.5 minutes in one embodiment of the invention.
Step S5: the release latch to cumulative number, to allow cumulative number is modified, and

The problem of communication connection is lost or disconnected to device, and now, this additional alarm part once judges accumulative time
Number exceedes default value and i.e. enables letter to the warning device output Failure Alarm of corresponding tire pressure monitoring sensor
Number, to occur that corresponding tire pressure monitoring sensor is lost or disconnected by this warning device prompting driver
The problem of communication connection, makes driver judge whether to need to process, here, if carried out tire pressure monitoring
Sensor failure is reported to the police after reporting to the police and is automatically disappeared, then may determine that without processing, supervise if carried out tire pressure
Survey sensor failure warning cannot automatically disappear all the time, then the corresponding tire pressure monitoring sensor of explanation is the most
Through losing, need to process in time.Pre-owing to carrying out the second of tire pressure monitoring sensor failure monitoring
If the time is far smaller than the first Preset Time carrying out tire pressure monitoring sensor loss monitoring, therefore, right
The condition that tire pressure monitoring sensor inefficacy carries out adding up triggers tire pressure monitoring sensor loss alarm relatively
Condition is easier to meet, and so, as long as cumulative number exceedes default value, just once can receive upper
After enabling signal, carry out tire pressure monitoring sensor Failure Alarm prompting at once, and then may be implemented in monitoring
The correct purpose triggering warning after losing to tire pressure monitoring sensor.
As in figure 2 it is shown, above-mentioned steps S5 can realize the most in the following ways:
Step S51: reset register mark position, with the release latch to cumulative number, performs afterwards
Step S52.
Step S52: judge whether register mark position is zero, in this way, then end step S5；As no,
Then perform step S53.
Step S53: judge during speed is more than described preset vehicle speed limit value, if continue second pre-
If the time does not receives described tire pressure, in this way, then perform step S54；As no, then perform step
Rapid S52.
Step S54: cumulative number is added 1, and by register mark position 1, so that cumulative number is carried out
Latch, forbid after one-shot, cumulative number repeatedly being revised, perform step S52 afterwards.
