Fig. 2 is the system control process figure of the utility model.
Specific implementation mode
The utility model is described in further detail below in conjunction with description of the drawings and specific implementation mode.
Referring to Fig. 1, a kind of vehicle tire pressure exception automatic speed reducing system, including central processing unit, signal processor, tire pressure letter
Number receiver, tyre pressure sensor, brake pedal position sensor, accelerator pedal position sensor, steering wheel angle sensor, vehicle
Fast sensor, load transducer, display, electric control braking valve and brake lamp, tyre pressure sensor quantity and vehicle tyre quantity one
It causes, a tyre pressure sensor is separately installed in each tire.The tyre pressure sensor and tire pressure signal receiver passes through nothing
Line mode connects, the tire pressure signal receiver, brake pedal position sensor, accelerator pedal position sensor, steering wheel
Rotary angle transmitter, vehicle speed sensor, load transducer are connect by wired connection mode with signal processor respectively；Described is aobvious
Show that device, electric control braking valve and brake lamp are connect by wired connection mode with central processing unit respectively；The signal processor
It is connect with central processing unit.Button is provided on the display, tyre pressure sensor passes through pressing on display after mounting
Each tyre pressure sensor is numbered in key so that each tire obtains corresponding unique number.
Referring to Fig. 1, the information such as the internal pressure of collected tire, temperature are sent to tire pressure by the tyre pressure sensor to be believed
Number receiver is sent these signals to after tire pressure signal receiver receives these wireless signals at signal processor
Reason；Treated, and signal will be sent to central processing unit, then after central processing unit is handled, and the information such as tire pressure will be sent to
It is shown on display.
Further include having phonetic alarm and alarm lamp further referring to Fig. 1, the phonetic alarm and alarm lamp
It is connect respectively with central processing unit by wired connection mode.
Referring to Fig. 2, a kind of control method of vehicle tire pressure exception automatic speed reducing system, including following step：
Step 1, vehicle launch, system starts, tire pressure signal receiver send tire pressure signal, brake pedal position
Sensor sends brake pedal position signal, accelerator pedal position sensor sends accelerator pedal position signal, steering wheel angle
Sensor sending direction disk angular signal, vehicle speed sensor send speed signal to signal processor.
Step 2, central processing unit receive and according to signal processor transmission come tire pressure signal, brake pedal position letter
Number, accelerator pedal position signal, steering wheel angle signal and speed signal, into one of four kinds of states below：
Safe condition：When tire pressure signal transmission is normal, and tire pressure, temperature are normal, central processing unit is judged as pacifying
Total state, alarm lamp extinguishing, phonetic alarm are not alarmed under this state.
Alarm condition：When tire pressure signal transmission is abnormal, central processing unit is judged as alarm condition；I.e. setting when
Between in the period, such as 30min, when central processing unit does not receive the tire pressure that signal processor transmits, central processing at this time
Device is judged as alarm condition.Or when the tire pressure value monitored is less than the low pressure alarming value of setting or more than setting
Alarm for high voltage value or tire pressure fall off rate reach the leakage alarm value of setting or collected tyre temperature is more than setting
High temperature alarm value and speed be less than VminOr it is more than VmaxWhen, central processing unit is judged as alarm condition.Under alarm condition,
The tyre serial number for the situation occur flickers display over the display, while phonetic alarm sends out " tire pressure monitoring no signal ", " tire
Press relatively low ", " tire pressure is higher ", " having a flat tire ", alarm voices, the alarm lamp such as " tyre temperature is higher " light.
Precarious position：When the tire pressure value monitored is less than the low pressure alarming value of setting or more than the high pressure of setting
Alarming value or tire pressure fall off rate reach the leakage alarm value of setting or collected tyre temperature is more than the height being arranged
Warm alarming value, and vehicle is to be not less than VminOr it is not more than VmaxSpeed when driving, central processing unit is judged as precarious position.Danger
Under dangerous state, the tyre serial number for abnormal conditions occur flickers display over the display, while phonetic alarm sends out that " tire pressure is inclined
It is low ", " tire pressure is higher ", " having a flat tire ", the alarm voices such as " tyre temperature is higher ", alarm lamp flicker；At the same time, centre
Reason device can be set according in vehicle speed sensor and the collected speed of load transducer and car load information, comparison central processing unit
The braking deceleration angle value set sends out a braking deceleration request to motor vehicle braking system, and electric control braking valve is started to work to vehicle
Braking deceleration is carried out, while brake lamp lights, and rearward vehicle passes out the information of this vehicle braking, and rear car is contributed to take peace
Full measure.The selection of braking deceleration can refer to following table.
。
Driver status：After vehicle enters precarious position, if driver does not take any measure, vehicle that can be maintained at
Precarious position, continuous braking slows down until speed drops to VminHereinafter, being transferred to alarm condition with rear vehicle.If driver takes
At least one letter in measure, i.e. brake pedal position sensor, accelerator pedal position sensor, steering wheel angle sensor three
Number changed, central processing unit judges that vehicle enters driver status, slow down at this time according to the operation of driver plus
Speed or go to action, but alarm lamp will continue to light, and phonetic alarm continues to send out alarm voice.
Above-mentioned Vmin、Vmax、Fmin、Fmax, the states such as signal transmission time period and high temperature and pressure alarming value, can be with
It is configured according to the actual demand of user.Braking deceleration a11、a12、…、anmValue can be set according to test result
It sets.
Referring to Fig. 1 to Fig. 2, the utility model can be monitored pressure of tire and temperature etc., occur having a flat tire,
The first time of the excessively high abnormal conditions of temperature alarms and carries out braking deceleration, reduces driving of the vehicle under abnormal tyre pressure state
Speed, to reduce vehicle because abnormal tyre pressure causes the risk for blowing out and occurring safety accident.In actual use, for anti-locking system
Situations such as breaking down, reporting by mistake influences the normal driving of driver, and driver can pass through the setting button on display
It closes automatic braking deceleration and only retains tire pressure monitoring function, or closed together together with tire pressure monitoring function.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, above structure
