Method includes the fault pre-alarming strategy of controller for vacuum pump；Start to carry out within the fault pre-alarming strategy 15 seconds after vehicle powers on
Alarm failure diagnosis, the reason of leading to failure by the concrete analysis of the state instruction of warning light, warning light have slow flash, middle dodge, is fast
Dodge and be always on four kinds of fault warning states.
Step S1 is less than lower voltage limit 9V when the vehicle voltage V measured is greater than upper voltage limit 16V or vacuum pump voltage V,
Warning light slow flash (2 seconds bright, goes out within 2 seconds).
Step S2, when any vacuum pump electric current I is greater than current limit upper limit 15A or vacuum pump electric current less than under current limit
2A is limited, dodges (1 second bright, goes out within 1 second) in warning light.
Step S3, when vacuum transducer failure, warning light quick flashing (0.3 second bright, goes out within 0.3 second).
Step S4, when vacuum absolute pressure P is for 2 seconds greater than pressure value upper limit 65Kpa, warning light is always on.
Step S5, when vacuum pump connects when continuous work 60 seconds, warning light is always on.
Step S6, when controller and vehicle open circuit, warning light is always on.
A kind of control method of controller for vacuum pump is suitable for a kind of above-described controller for vacuum pump, the control
Method processed further includes the control strategy of controller for vacuum pump, and system has released situation without alarm or alarm, and vacuum transducer is normal
Work, vacuum transducer acquire vacuum degree signal, and entire car controller collects analog voltage Vac signal meter according to vacuum transducer
Calculate vacuum absolute pressure P value；When any one vacuum pump continues working 25 seconds, when vacuum absolute pressure P is greater than the set value
45Kpa, motor stop working；When a vacuum pump operating current is normal, another vacuum pump electric current I1 is greater than maximum upper limit electricity
15A is flowed, high current vacuum pump work is stopped；Two vacuum pump electric current I are all larger than maximum current limit 15A and vacuum absolute pressure
Power P, which is greater than, limits pressure 65Kpa, and two vacuum pumps stop working.
As a kind of preferred control strategy of alarm device quick flashing, when vacuum transducer failure, warning light quick flashing, two at this time
Vacuum pump takes turns to operate each 5 seconds, keeps vacuum source continuous.
A kind of method releasing the fault pre-alarming is suitable for a kind of control method of controller for vacuum pump are as follows: works as warning light
State when slow flash, middle sudden strain of a muscle or when quick flashing, vehicle need to re-power recovery.
Further, when vacuum absolute pressure P is for 2 seconds greater than pressure value upper limit P1, warning light is always on, when vacuum is exhausted
Alarm releases when being less than irreducible minimum level pressure force value 25Kpa to pressure P, restores normal.
Further, if warning light is still always on, vacuum pump is even when continuous work 60 seconds, and warning light is always on, when vacuum is absolute
Alarm releases when pressure P is less than irreducible minimum level pressure force value 25Kpa.
Further, if warning light is still always on, controller is electrically connected, at this time by detection circuit failure again with vehicle
All clear restores normal.
The vacuum pump voltage rating V1=DC13V；Operating voltage V2=DC9V~DC16V；Operating current I0≤25A.
The vacuum transducer passes through the analog voltage Vac value measured and is converted into vacuum absolute pressure P, institute by calculating
Stating analog voltage Vac signal feedback range is 0.5V~4.5V, and the specific formula for calculation of vacuum absolute pressure value is P=(Vac/5+
0.00095)/0.0081, calculating current vacuum absolute pressure value can show in carload instrument.
The above is only a kind of a kind of preferred embodiment of controller for vacuum pump of the utility model, not to this
The technical scope of utility model imposes any restrictions, and all foundation the technical essence of the utility model are to made by above embodiment
Several modifications and improvements are still within the scope of the technical solutions of the present invention.
