Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures. In addition, the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
Example one
Fig. 1 is a flowchart of a tank pressure monitoring method according to an embodiment of the present invention, which may be applied to monitoring pressure in a tank of a vehicle, where the method may be implemented by a tank pressure monitoring device, which may be implemented in a hardware and/or software manner and is generally integrated in a vehicle, where the vehicle may be a conventional fuel-powered vehicle or a hybrid vehicle. Referring to fig. 1, the method may include the steps of:
and S110, acquiring current state information of the engine and a pressure value of the pressure sensor.
The pressure sensor of this embodiment is arranged on the oil tank to link to each other with the controller, be used for the pressure value in the real-time supervision oil tank, and send the pressure value of monitoring for the controller. The type and model of the pressure sensor can be selected according to actual needs, and the embodiment is not limited. The type of fuel tank may be selected according to the vehicle type, for example, a high-pressure fuel tank may be used for a hybrid vehicle. The current state information of the engine is information reflecting the current state of the engine, and for example, the current state information can comprise the states of engine operation and engine non-operation, and when the engine is operated, the current state information can also comprise two states of fuel consumption of the engine and fuel consumption and oil vapor desorption of the engine according to actual requirements.
And S120, if the engine works and the pressure value is smaller than the first pressure threshold corresponding to the current state information, controlling the engine to stop working and carrying out early warning indication.
The size of the first pressure threshold value can be determined according to the model of the vehicle, the pressure resistance of the oil tank and other characteristics. It will be appreciated that as the engine operates, the fuel in the fuel tank is reduced and the pressure is reduced, in order to maintain a balanced pressure in the fuel tank, a supply of ambient air is required. Optionally, when the engine only consumes fuel, along with the consumption of the fuel, outside air enters the fuel tank to maintain pressure balance in the fuel tank, and if it is monitored that the pressure value in the fuel tank is smaller than the first pressure threshold corresponding to the current state information, conditions such as fuel tank cracking, fuel leakage or pipeline rupture may exist. Optionally, the early warning indication can be performed through the early warning indicator, the color and the flashing frequency of the early warning indicator can be customized, for example, the early warning indicator can flash red when the monitored pressure value is smaller than the first pressure threshold, and the early warning indicator can be not on or always keep green under normal conditions. Of course, the alarm can also be used for alarm indication, or the contact information of the relevant user can also be searched, and the user can be informed in the forms of short messages, telephone calls, mails and the like.
Optionally, when the engine consumes fuel and desorption oil vapour simultaneously, the pressure in the oil tank reduces along with the reduction of fuel, and the outside air partly gets into the oil tank through pipeline and carbon tank for maintain the pressure balance in the oil tank, partly get into the desorption pipeline and realize the desorption. Normally, the pressure in the tank is substantially the same as if the engine had only consumed fuel. If the pressure in the oil tank is monitored to be obviously reduced at the moment, the pipeline communicated with the outside air possibly fails, and the outside air cannot enter the carbon tank. On one hand, fuel in the oil tank is reduced, and the pressure is reduced, on the other hand, in order to realize desorption, air can be sucked from the oil tank, so that the pressure in the oil tank is sharply reduced. In order to ensure safety, when the pressure of the oil tank is monitored to drop suddenly, the engine is controlled to stop working, and a user is informed in time.
And S130, displaying the current pressure value of the oil tank.
The display mode can be set according to the demand, for example can show through the display screen, also can show through emitting diode, makes the user can know the pressure value in the oil tank in real time, and the troubleshooting in advance improves the security.
The embodiment of the invention provides an oil tank pressure monitoring method, which is characterized in that the pressure in an oil tank is monitored in real time through a pressure sensor on the oil tank, so that the automatic monitoring of the pressure of the oil tank is realized, when an engine works and the pressure in the oil tank is smaller than a first pressure threshold corresponding to current state information, the engine is controlled to stop working and early warning indication is carried out, the condition that related parts are invalid due to continuous working even if the pressure in the oil tank is too high is effectively prevented, and the safety is improved.
Example two
Fig. 2 is a flowchart of a tank pressure monitoring method according to a second embodiment of the present invention, which is optimized based on the above-mentioned embodiments, and referring to fig. 2, the method may include the following steps:
and S210, acquiring current state information of the engine and a pressure value of the pressure sensor.
S220, judging whether the engine works or not, if so, executing S230, and otherwise, executing S250.
And S230, whether the pressure value is smaller than a first pressure threshold corresponding to the current state information is judged, if yes, S240 is executed, and if not, S230 is executed.
And S240, controlling the engine to stop working and carrying out early warning indication.
In this embodiment, taking two states of desorbing oil vapor and consuming only fuel as examples when the engine is working, correspondingly, S240 may include:
if the engine is in a fuel oil state at present, when the pressure value is smaller than a fuel oil pressure threshold value corresponding to the fuel oil state, controlling the engine to stop working and informing a user of the fault of the fuel oil tank;
if the engine is in the desorption state at present, when the pressure value is smaller than the desorption pressure threshold value of the desorption state, the engine is controlled to stop working and the user is informed of the fault of the atmospheric pipeline connected with the carbon tank, and the desorption pressure threshold value is smaller than the fuel pressure threshold value.
The fuel pressure threshold is a safe pressure that the fuel tank can withstand when the engine is only consuming fuel. Exemplarily, referring to fig. 3, fig. 3 is a partial schematic diagram of an engine operating in a fuel state according to a second embodiment of the present invention. In this case, the fuel in the fuel tank 3 enters the engine fuel rail through the fuel supply line D, and as the fuel is consumed, the outside air enters the canister 1 through the atmospheric line a, and then enters the fuel tank 3 through the adsorption line B, so as to maintain the pressure balance in the fuel tank 3. The arrows indicate the flow of air and fuel. The pressure sensor 4 on the fuel tank 3 monitors the pressure in the fuel tank 3 in real time and sends the pressure value to the controller 5, and when the controller 5 determines that the pressure value is smaller than the fuel pressure threshold value, the controller 5 controls the engine to stop working and informs a user of the fault of the fuel tank 3. The notification means may include one or more of a flashing light notification, a voice notification, a short message notification, a telephone notification, and a mail notification.
The desorption pressure threshold is the safe pressure which can be borne by the oil tank when the engine is in a desorption state. Exemplarily, referring to fig. 4, fig. 4 is a partial schematic view of an engine in a desorption state according to a second embodiment of the present invention. Under normal conditions, the outside air passes through atmosphere pipeline A and gets into carbon tank 1, then the part gets into desorption pipeline C and carries out the desorption, and the part gets into adsorption pipeline B and gets into oil tank 3. If the controller 5 monitors that the pressure value of the pressure sensor 4 is suddenly reduced and is smaller than the desorption pressure threshold value, the engine is controlled to stop working, and the user is informed of the fault of the atmospheric pipeline A. The reason is when atmospheric line A trouble, and the unable absorption pipeline B and the desorption pipeline C that get into of outside air for realize the desorption, and the air in the oil tank 3 gets into desorption pipeline C through absorption pipeline B, leads to the pressure in the oil tank 3 to reduce suddenly. The desorption pressure threshold in this embodiment is less than the fuel pressure threshold.
And S250, whether the pressure value is larger than a second pressure threshold corresponding to the current state information or not, if so, executing S260, otherwise, returning to execute S250.
And S260, controlling a ventilation electromagnetic valve to be opened so that the oil vapor in the oil tank is discharged to the outside air through the ventilation electromagnetic valve.
It will be appreciated that when the engine is not operating, the fuel vapour produced by evaporation of the fuel in the tank will remain stored in the tank, and when the ambient temperature rises, the pressure in the tank will change significantly. Exemplarily, referring to fig. 5, fig. 5 is a partial schematic view of an engine that is not operated according to a second embodiment of the present invention. When the controller 5 monitors that the pressure value of the pressure sensor 4 is greater than the second pressure threshold value, the ventilation electromagnetic valve 2 can be controlled to be opened, so that oil vapor in the oil tank 3 enters the carbon tank 1 through the adsorption pipeline B, then enters the atmosphere pipeline A from the carbon tank 1 and is discharged to the outside air, the automatic control of the pressure in the oil tank 3 is realized, the problems of oil tank 3 or pipeline breakage and the like caused by the overlarge pressure of the oil tank 3 are avoided, and the safety is improved. And the manual control of a user is not needed, so that the labor is saved.
And S270, displaying the current pressure value of the oil tank.
The second embodiment of the invention provides an oil tank pressure monitoring method, which can automatically monitor the pressure in an oil tank of an engine in different states on the basis of the first embodiment, perform early warning indication when the pressure in the oil tank exceeds a safety range, timely notify a user, prevent parts such as the oil tank from failing and improve the safety. And can show the pressure value of oil tank for the user in real time, make the user in time know the pressure of oil tank, avoid causing dangerous condition because of warning instruction untimely.
