Referring to fig. 1, a schematic flow chart of an automatic Control method for an air cleaner for a vehicle according to an embodiment of the present disclosure is mainly applied to an on-board controller (Electronic Control Unit, abbreviated as ECU) of the vehicle. As shown in fig. 1, the automatic control method of the air cleaner for vehicles mainly includes the following steps:
s101, detecting whether an engine of the vehicle is in a stop state or not if a blockage alarm signal corresponding to an air filter of the vehicle is received;
the automatic control method provided by the embodiment of the disclosure is mainly used for automatic maintenance of the air filter on the vehicle, and the related vehicle can comprise a truck and other vehicles with the air filter.
In this embodiment, the air cleaner is preferably a maintenance-free air cleaner, the maintenance-free air cleaner is provided with a cage-type airflow pipe inside a main filter element, the cage-type airflow pipe is provided with an air inlet, compressed air is introduced from the outside of an air filter housing, the cage-type airflow pipe is composed of an end-part annular airflow pipe at each of two ends and a cross-bar-type airflow pipe distributed circumferentially, air outlets are uniformly distributed on the outer side of the cross-bar-type airflow pipe, compressed air inside a pipeline can be guided to the direction of the main filter element to sweep the main filter element, the safety filter element is not swept, dust and impurities on the outer side of the main filter element fall after being swept by the airflow, and the air filter is discharged from an air filter end cover or a dust.
In addition, when the vehicle air cleaner air outlet pipe is implemented specifically, a sensor and an alarm switch can be arranged on the vehicle air cleaner air outlet pipe, the sensor can be used for detecting the blocking state in the air cleaner, judging whether the blocking condition needing to be controlled and cleaned occurs or not, and specifically judging the blocking state through detecting the negative pressure value of the air cleaner air outlet pipe. For example, when the negative pressure value of the air outlet pipe is detected to be larger than a preset value, the corresponding alarm switch is enabled to send an alarm signal. The preset value according to which the jam state is determined may vary from vehicle type to vehicle type, for example, a conventional truck may be set at about 6.5 kPa. When the alarm switch sends out an alarm signal, the vehicle-mounted controller of the vehicle receives the alarm signal and starts a subsequent automatic control process.
Considering that the performance and normal operation of the automobile are influenced by maintaining the air filter in the operation of the automobile, the vehicle-mounted controller firstly detects whether the engine in the automobile is in a stop state after receiving the alarm signal. And only when the engine is in a stop state, the vehicle-mounted controller controls the corresponding element to perform a subsequent automatic cleaning program, otherwise, the controller stops the program to continue.
S102, if yes, controlling an electromagnetic valve of the vehicle to be opened so that gas in the vehicle-mounted air storage cylinder enters the air filter through the electromagnetic valve;
and when the vehicle-mounted controller detects that the engine of the vehicle is in a stop state, the vehicle-mounted controller performs a subsequent automatic cleaning program.
The vehicle is also internally provided with an electromagnetic valve and a vehicle-mounted air cylinder, and the electromagnetic valve is respectively communicated with the vehicle-mounted air cylinder and the air filter. The vehicle-mounted air reservoir can be an air reservoir which is arranged independently and specially used for cleaning the air filter, and the air reservoir used for braking and gear shifting is preferred in the embodiment. When the air cleaner is used, the vehicle-mounted controller can send a signal to control the electromagnetic valve to be opened, so that the air stored in the vehicle-mounted air storage cylinder starts to circulate to the air cleaner.
In view of the fact that the gas flushed into the air cleaner during cleaning needs to satisfy a certain pressure, another embodiment of the present disclosure further adds a pressure regulating valve for pressure regulation, and after the step of controlling the solenoid valve of the vehicle to open if the gas is the gas in S102, the method may further include:
controlling the electromagnetic valve of the vehicle to open so that gas in the vehicle-mounted gas cylinder enters the pressure regulating valve for pressure regulation through the electromagnetic valve;
and conveying the gas with the pressure regulated to a preset pressure value into the air filter.
Considering that an on-board air reservoir in a vehicle is generally provided for braking gear shifting, the stored air pressure is not necessarily suitable for cleaning a filter element of an air cleaner, and the air pressure can be adjusted using the above-described pressure regulating valve.
In the present embodiment, the pressure regulating valve is respectively communicated with the electromagnetic valve and the air cleaner, and the preset pressure value is set differently according to different vehicles, for example, the range of the required air pressure value of a conventional truck may be: 0.6 MPa to 1 MPa. And the pipeline communicated between the pressure regulating valve and the air filter is a compressed gas pipeline.
S103, controlling the air filter to perform preset automatic cleaning operation by using the received gas;
the vehicle-mounted controller can also control the air filter to receive the gas in the S102 to perform a preset cleaning program. When the air filter is specifically implemented, the air filter can be a maintenance-free air filter, the air filter needs gas to blow and clean the main filter element of the air filter, dust and impurities outside the main filter element drop after being blown and swept by the gas flow, and the dust and impurities are discharged from the gas outlet pipe along with the gas flow.
And S104, if the air filter is detected to be cleaned, controlling the electromagnetic valve to be closed.
When the vehicle-mounted controller detects that the air filter is cleaned, an instruction is sent to control the electromagnetic valve to be closed, and the gas circulation between the vehicle-mounted air storage cylinder and the air filter is cut off.
The step of detecting that the air cleaner is cleaned may include any one of the following two modes:
on the first hand, the air filter is controlled to execute automatic cleaning operation for a preset time;
when the automatic cleaning method is implemented, a preset time length for automatic cleaning of the air filter needs to be set on the vehicle-mounted controller in advance, for example, the automatic cleaning time is set to be 3 minutes, when the vehicle-mounted controller detects that the engine is in a stop state, the automatic cleaning program of the air filter is started to start automatic cleaning, and after the automatic cleaning program is maintained for 3 minutes, the vehicle-mounted controller controls the electromagnetic valve to be closed to stop the cleaning program.
When the preset time duration is set, a reasonable range can be set according to the model and the type of the air filter. Thereby ensuring that the filter element of the air filter can be cleaned thoroughly.
A second aspect, receiving the blockage warning signal corresponding to the vehicle air filter;
the disclosure also discloses another method for judging the cleaning completion of the air filter, which is carried out by closing the air filter blockage alarm switch. When the air filter alarm switch is turned on and continuously sends an alarm signal to the vehicle-mounted controller, the vehicle-mounted controller can keep the electromagnetic valve in an open state, gas in the air filter can also keep circulating, and the filter element of the air filter can be continuously cleaned. When the blockage alarm switch (or the pressure sensor) of the air outlet pipe of the air filter detects that the negative pressure value of the air outlet pipe is smaller than the preset value, the alarm switch is closed, and the alarm signal is stopped being sent. The vehicle-mounted controller determines that the blockage alarm signal is relieved, sends a signal to close the electromagnetic valve, and stops the automatic cleaning program.
After the alarm signal is removed, the vehicle-mounted controller sends a signal to close the electromagnetic valve, cleaning is stopped, and waste of vehicle energy can be effectively prevented.
Of course, the two manners of judging the completion of cleaning can be combined, so that the problems of insufficient cleaning time and vehicle energy waste can be comprehensively avoided.
In addition, on the basis of the above embodiment, when the alarm switch sends an alarm signal, information that the air cleaner needs to be maintained is displayed on an instrument panel of the vehicle, so that a vehicle owner can conveniently control the available state of the air cleaner in time.
According to the automatic control method for the vehicle air filter, which is provided by the embodiment of the disclosure, the air filter is combined with the vehicle-mounted controller, so that the automatic cleaning and maintenance of the air filter are realized. The vehicle-mounted controller controls the switch of an electromagnetic valve which is communicated with the vehicle-mounted air storage cylinder and the air filter, so that the gas stored in the vehicle-mounted air storage cylinder can circulate into the air filter through the compressed gas pipe to clean the air filter. Gaseous circulation arrives before the air cleaner, the air-vent valve that sets up in addition between air cleaner and solenoid valve is right gas carries out the pressure regulating, guarantees to flow into under the condition of air cleaner's filter core can be protected to air cleaner's gas, right air cleaner carries out abundant, effectual clearance, has guaranteed the operating efficiency and the performance of vehicle.

The present embodiment provides an automatic control method different from the above embodiments in that the method is applied to an automatic control system of an air cleaner for a vehicle. As shown in fig. 2, the method mainly comprises the following steps:
s201, when the air filter detects blockage, sending a blockage alarm signal to the vehicle-mounted controller;
and after a pressure sensor arranged on the air outlet pipe of the air filter detects that the negative pressure value of the air outlet pipe is greater than a certain preset value, an alarm switch arranged on the air outlet pipe of the air filter is turned on, and the blockage alarm signal is sent to the vehicle-mounted controller.
S202, the vehicle-mounted controller receives the blockage alarm signal, detects that an engine of the vehicle is in a stop state, and controls the electromagnetic valve to be opened when the engine is in the stop state;
and after the vehicle-mounted controller receives the jam alarm signal, starting to detect whether an engine of the vehicle is in a stop state. And when the engine is detected to be in a stop state, controlling the electromagnetic valve to be opened.
S203, the electromagnetic valve is opened under the control of the vehicle-mounted controller and is respectively communicated with the vehicle-mounted air storage cylinder and the air filter;
s204, allowing gas in the vehicle-mounted air reservoir to enter the air filter through the electromagnetic valve;
and the gas in the vehicle-mounted gas storage cylinder passes through the electromagnetic valve through the compressed gas pipe and flows into the air filter from the air inlet of the air filter.
S205, the air filter executes a preset automatic cleaning action by using the received gas;
the air filter is preferably a maintenance-free air filter, and after the air filter receives the gas, the main filter element of the air filter can be automatically swept, so that the maintenance work of the air filter is realized.
S206, when the air filter detects that the air filter is cleaned, the vehicle-mounted controller controls the electromagnetic valve to be closed;
the specific step of detecting the completion of cleaning the air filter by the air filter comprises the following two steps:
on the first hand, the air filter is controlled to execute automatic cleaning operation for a preset time;
a second aspect, receiving the blockage warning signal corresponding to the vehicle air filter;
when the pressure sensor detects that the pressure value of the air outlet pipe of the air filter is smaller than the preset pressure value, the alarm switch is turned off, and the alarm signal is relieved.
