Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
The method, the device, the vehicle and the storage medium for controlling the start and stop of the vehicle-mounted air compressor according to the embodiment of the application are described below with reference to the accompanying drawings. The application provides a start-stop control method of a vehicle-mounted air compressor, which can detect the actual pressure of an air storage cylinder and the actual air pressures of a front axle and a rear axle, and starts the vehicle-mounted air compressor when the detected actual pressure is lower than the first starting pressure of the vehicle-mounted air compressor or the pressure mean value obtained by the actual air pressures of the front axle and the rear axle is lower than the second starting pressure, and closes the vehicle-mounted air compressor when the detected actual pressure is larger than or equal to the first closing pressure of the vehicle-mounted air compressor or the pressure mean value is larger than or equal to the second closing pressure. From this, through setting for two kinds of modes of opening and stopping, can open and stop the air compressor machine through another kind of mode when a certain mode trouble, only one kind has been solved and has been opened and stop the mode among the correlation technique, when a certain link breaks down, can lead to the problem that the vehicle-mounted air compressor machine can't start, optimizes vehicle-mounted air compressor machine's performance.
Specifically, fig. 1 is a schematic flow chart of a start-stop control method of a vehicle-mounted air compressor provided in an embodiment of the present application. As shown in fig. 1, the start-stop control method of the vehicle-mounted air compressor comprises the following steps:
in step S101, it is detected whether the vehicle air compressor is activated when the actual pressure of the air reservoir is lower than a first activation pressure.
The first starting pressure may be a starting pressure preset by a user, may be a starting pressure obtained through a limited number of experiments, or may be a starting pressure obtained through a limited number of computer simulations, which is not specifically limited herein.
Specifically, this application embodiment can detect the actual pressure of gas receiver through automatically controlled desicator, under the normal condition, when detecting actual pressure and being less than first starting pressure, if first starting pressure can be for the starting pressure that the host computer factory set for, automatically controlled desicator can send high effective signal for on-vehicle air compressor machine controller, if on-vehicle air compressor machine controller receives the high effective signal that automatically controlled desicator sent after, control on-vehicle air compressor machine and start, if on-vehicle air compressor machine controller does not receive the high effective signal that automatically controlled desicator sent, then do not control on-vehicle air compressor machine and start.
In step S102, when it is detected that the actual pressure is lower than the first start pressure, the vehicle-mounted air compressor is not started, and the average value of the actual air pressures of the front axle and the rear axle of the air reservoir is calculated.
It should be understood that, if the vehicle-mounted air compressor is not started when the actual pressure is detected to be lower than the first starting pressure, the vehicle-mounted air compressor controller of the embodiment of the application detects the air pressure values of the front axle and the rear axle through the CAN bus, so as to calculate the average actual air pressure value of the front axle and the rear axle.
In step S103, if the actual air pressure average value is lower than the second activation pressure, the vehicle-mounted air compressor is activated.
The second starting pressure may be a starting pressure preset by a user, may be a starting pressure obtained through a limited number of experiments, or may be a starting pressure obtained through a limited number of computer simulations, which is not specifically limited herein.
Specifically, if the actual air pressure average value is lower than the second starting pressure, which may be 650kpa, for example, the on-board air compressor controller controls the on-board air compressor to start pumping.
Optionally, in some embodiments, after starting the vehicle-mounted air compressor, the method further includes: judging whether the vehicle-mounted air compressor enters a working mode or not; and if the vehicle-mounted air compressor does not enter the working mode after being started, judging a starting fault, and stopping starting the vehicle-mounted air compressor.
Particularly, if the vehicle-mounted air compressor is controlled to be started and does not work normally, the starting fault of the vehicle-mounted air compressor is described, and the vehicle-mounted air compressor is stopped to be started for avoiding safety.
From this, when detecting that actual pressure is less than first starting pressure, but vehicle air compressor machine did not start, this application embodiment can be through judging whether the pressure mean value that the actual atmospheric pressure of front axle and rear axle obtained is less than second starting pressure, realizes the control to vehicle air compressor machine.
Further, in some embodiments, the start-stop control method of the vehicle-mounted air compressor further includes: and when the actual pressure is detected to be greater than or equal to the first closing pressure of the vehicle-mounted air compressor or the average pressure value is detected to be greater than or equal to the second closing pressure, the vehicle-mounted air compressor is closed.
The first closing pressure and the second closing pressure may be closing pressures preset by a user, may be closing pressures obtained through limited experiments, or may be closing pressures obtained through limited computer simulations, and are not specifically limited herein.
It should be understood that if the actual pressure is greater than or equal to the first closing pressure of the vehicle-mounted air compressor, for example, the first closing pressure may be a closing pressure set by a host factory, the electronic control dryer stops sending the high effective signal to the vehicle-mounted air compressor controller, and when the vehicle-mounted air compressor controller cannot receive the high effective signal sent by the electronic control dryer, the vehicle-mounted air compressor is controlled to stop working; if the average pressure value is greater than or equal to the second closing pressure, such as 850kPa, the vehicle-mounted air compressor controller can also control the vehicle-mounted air compressor to stop working.
Optionally, in some embodiments, after starting the vehicle-mounted air compressor, the method further includes: collecting state parameters of a vehicle-mounted air compressor; and if the actual value of any one of the state parameters is in an abnormal interval, sending a second fault signal to the vehicle control unit, so that the vehicle control unit executes a fault protection action on the vehicle-mounted air compressor.
In some embodiments, the state parameter at least includes one of an actual operating voltage, an actual operating current, an actual operating temperature, and an actual input voltage of the vehicle-mounted air compressor.
The abnormal interval may be an abnormal interval preset by a user, an abnormal interval obtained through a limited number of experiments, or an abnormal interval obtained through a limited number of computer simulations, and is not specifically limited herein.
Specifically, the vehicle-mounted air compressor controller can monitor the working state of the vehicle-mounted air compressor in real time when the air compressor works, and the monitored state parameters can include any one or more of the voltage when the vehicle-mounted air compressor works, the current when the vehicle-mounted air compressor works, the temperature when the vehicle-mounted air compressor works and the input voltage of the vehicle-mounted air compressor. If a condition parameter is monitored to be abnormal, if the parameter value is in an abnormal interval, the normal work of the Vehicle-mounted air compressor is influenced, the embodiment of the application can send a second fault signal to a VCU (Vehicle control unit) and an instrument, and after receiving the second fault signal, the VCU sends a shutdown signal to the Vehicle-mounted air compressor to start fault protection and stop the work of the air compressor. When the instrument receives the corresponding fault message information, the corresponding vehicle-mounted air compressor fault lamp can be turned on and the fault reason can be displayed.
Therefore, the integrated controller of the vehicle-mounted air compressor can detect the working state of the vehicle-mounted air compressor in real time, and when the vehicle-mounted air compressor breaks down, fault information can be fed back to the VCU and the instrument, and the vehicle-mounted air compressor is shut down to be protected. In addition, the vehicle-mounted air compressor adopts a built-in cooling fan, so that the size of the air compressor and the number of connectors are reduced, the motor and the controller can be better cooled, and the controller is favorable for detecting the working state of the fan.
Optionally, in some embodiments, the start-stop control method of the vehicle-mounted air compressor further includes: detecting whether the vehicle is powered on or not; after the whole vehicle is detected to be electrified, detecting whether the current state of the vehicle-mounted air compressor meets the working condition; and if the current state meets the working condition, judging that the self-checking of the vehicle-mounted air compressor is normal, and otherwise, sending a first fault signal to fault reminding equipment.
It should be understood that when the fault disappears, the vehicle-mounted air compressor is powered on again for self-checking, whether the current state of the vehicle-mounted air compressor meets the working condition is detected, namely whether the state of the vehicle-mounted air compressor is normal is detected, and if the self-checking of the vehicle-mounted air compressor is abnormal, a first fault signal is sent to a fault reminding device, such as an instrument.
Therefore, the vehicle-mounted air compressor controller can perform self-checking after being powered on, whether the state of the vehicle-mounted air compressor is normal or not is detected, and the performance of the vehicle-mounted air compressor is further optimized.
In order to enable those skilled in the art to further understand the start-stop control method of the vehicle-mounted air compressor according to the embodiment of the present application, detailed descriptions are provided below with reference to specific embodiments.
As shown in fig. 2, fig. 2 is a schematic structural diagram of an integrated controller assembly of an electric air compressor, which mainly includes: the air compressor comprises an air filter 1, an air compressor controller 2, an oil-free air compressor 3 and a fixed support 4. Therefore, the air compressor controller and the vehicle-mounted air compressor can be integrated, the structure is compact, the occupied space is small, the arrangement convenience of the whole vehicle can be improved, and the cost and the weight of the whole vehicle are reduced. It should be noted that the integrated controller assembly of the vehicle-mounted air compressor can be set and modified through software, and can be rapidly matched with a vehicle type.

and S301, starting.
And S302, after the whole vehicle is electrified, the vehicle-mounted air compressor controller is awakened, and the vehicle-mounted air compressor controller is initialized and self-checked.
Specifically, the pin E is connected with ON and powered ON, and the vehicle-mounted air compressor is awakened by high-level 24V. If the abnormal working state of the vehicle-mounted air compressor is detected during self-checking, fault information is displayed to the instrument through the CAN; if the self-check is not problematic, the control signal is waited for.
It should be noted that the vehicle-mounted air compressor controller is in a sleep state before the E pin receives the 24V high voltage, and the vehicle-mounted air compressor can be awakened only when the E pin is at the 24V high level, and the air compressor is not allowed to be awakened through the enable signal. In addition, the vehicle-mounted air compressor controller can send messages to the bus only after being awakened, and the messages are not allowed to be sent in the sleeping state of the vehicle-mounted air compressor controller.
And S303, the vehicle-mounted air compressor controller receives an enable signal.
S304, whether the vehicle-mounted air compressor controller receives a high level signal or not is judged, if yes, step S305 is executed, and if not, step S308 is executed.
And S305, controlling the vehicle-mounted air compressor to work.
If the vehicle-mounted air compressor receives the disable signal, step S307 is executed.
And S306, judging whether the vehicle-mounted air compressor controller receives a low level signal, if so, executing the step S307, otherwise, executing the step S305.
Wherein the low level signal may be sent by the EAPU (e.g., an electronically controlled dryer).
And S307, controlling the vehicle-mounted air compressor to stop working.
It should be noted that, if the continuous operation time of the vehicle-mounted air compressor reaches the preset time, for example, 10min, the vehicle-mounted air compressor may also be controlled to stop operating.

And S310, judging whether the average value of the air pressure of the front axle and the rear axle is larger than or equal to 850kpa, if so, skipping to execute the step S307, otherwise, continuously controlling the vehicle-mounted air compressor to work.
According to the start-stop control method of the vehicle-mounted air compressor, whether the vehicle-mounted air compressor is started when the actual pressure of the air storage cylinder is lower than the first starting pressure or not can be detected, the vehicle-mounted air compressor is not started when the actual pressure is lower than the first starting pressure, the actual air pressure mean values of the front axle and the rear axle of the air storage cylinder are calculated, and the vehicle-mounted air compressor is started when the fruit air pressure mean value is lower than the second starting pressure. Therefore, when a certain starting and stopping mode fails, the air compressor can be started and stopped in another mode, the problem that the vehicle-mounted air compressor cannot be started due to the fact that only one starting and stopping mode exists in the related technology and a certain link fails is solved, and the performance of the vehicle-mounted air compressor is optimized.
