Specific embodiment
The present invention is further described in detail below in conjunction with specific embodiment and accompanying drawing.It is only intended to explain in detail
Specific embodiments of the present invention are stated, any limitation is not produced to the present invention, protection scope of the present invention is with claims
It is defined.
Embodiment one：
Reference picture 1, the embodiment of the present invention proposes a kind of detection method of air conditioner filter of vehicle, including：
Step S001, obtains the air-out gear of vehicle air conditioning, and obtains its corresponding standard airflow value according to air-out gear；
The airflow value of the corresponding air-out of different air-out gears of vehicle air conditioning is also different, such as the corresponding air quantity of " high wind " gear
Value airflow value more corresponding than other air-out gears will be big.
Step S002, the discharge quantity of fan value of detection Current vehicle air conditioner filter output；
The discharge quantity of fan value that Current vehicle air conditioner filter is exported can be detected by air flow sensor.
Step S003, if the difference between discharge quantity of fan value and standard airflow value is more than default air quantity difference, judges car
Air conditioner filter needs to change.
Because the characteristic of the filter paper used in air conditioner filter of vehicle is：Ventilate and obstructed particulate matter, so when vehicle is empty
When adjusting the difference between the discharge quantity of fan value and standard airflow value of filter output to be more than default air quantity difference, it is believed that vehicle air conditioning
Filter by some debris block it is not smooth or with other failures, it is necessary to be changed to air conditioner filter of vehicle.And
If the difference between the discharge quantity of fan value and standard airflow value of air conditioner filter of vehicle output is less than or equal to default air quantity difference
When, then it is assumed that air conditioner filter of vehicle is in normal work, it is not necessary to change.The value that standard airflow value can be selected is：Work as car
Air conditioner filter in preferable operation, corresponding discharge quantity of fan value.Default air quantity difference is that the air quantity for pre-setting is poor
Value, such as 5 cubic metres per second.
The present embodiment obtains its corresponding standard air quantity by obtaining the air-out gear of vehicle air conditioning according to air-out gear
Whether value, compare the difference between the discharge quantity of fan value and standard airflow value of Current vehicle air conditioner filter output more than default wind
Amount difference, in the way of judging whether air conditioner filter of vehicle needs to change, solves air conditioner filter of vehicle in the prior art
Filter capacity is lost, but has continued to using, caused the ropy problem of passenger cabin air of vehicle, while also solving
Air conditioner filter of vehicle of having determined still has ability to work but is replaced in advance, causes excessive maintenance and produces the problem of waste.This reality
Apply example can automatic detection vehicle air conditioner filter whether normal work, whether need change, user is actively gone
Judge whether air conditioner filter of vehicle needs to change, allow the use vehicle air conditioning that user is more comfortable.
