[0048] In the technical solution of this application, the collection, storage, use, processing, transmission, provision and disclosure of information such as financial data or user data involved shall comply with the provisions of relevant laws and regulations and shall not violate public order and good morals.

[0049] It should be noted that in the embodiments of the present application, certain software, components, models and other existing solutions in the industry may be mentioned, and they should be regarded as exemplary. Their purpose is only to illustrate the feasibility of implementing the technical solution of the present application, but it does not mean that the applicant has or will necessarily use the solution.

[0050] It should also be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0051] The control method, device, vehicle and medium for connecting a vehicle to a fuel tank of the present application can be used in the field of vehicle control technology, and can also be used in any field other than the field of vehicle control technology, such as the field of fuel tank control technology, etc. The application field of the control method, device, vehicle and medium for connecting a vehicle to a fuel tank of the present application is not limited.

[0052] The vehicle-connected fuel tank control method, device, vehicle and medium of the present application can be applied to vehicles with multiple fuel tanks. As long as the vehicle includes at least two fuel tanks and the fuel tanks are connected by a connecting pipe, the vehicle-connected fuel tank control method, device, vehicle and medium of the present application can be applied.

[0053] First, the terms involved in this application are explained:

[0054] Fuel pressure refers to the physical quantity of the vertical force exerted on the fuel tank or related pressure detection elements per unit area when the fuel is stored in the fuel tank, usually expressed in Pascal (Pa).

[0055] Fuel flow rate refers to the speed at which fuel flows through the fuel system, usually expressed in units of volume (such as liters or gallons) per unit of time (such as minutes or hours).

[0056] As the demand for vehicle range continues to increase, the demand for vehicle fuel storage is also increasing. However, a single fuel tank is limited by the vehicle layout space and cannot expand its capacity indefinitely. Therefore, dual fuel tank or even multi-tank solutions are being used more and more.

[0057] In the related art, when a vehicle adopts a multi-tank solution, a connecting pipe is usually used to connect the tanks. The circulation and isolation of fuel between the tanks can be achieved by controlling the solenoid valves corresponding to the connecting pipe.

[0058] However, the relevant solutions can only realize the interconnection of multiple fuel tanks, and cannot perform real-time monitoring and intelligent control of the connected fuel tanks. In abnormal situations such as oil pipe rupture, detachment, fuel theft, etc., it is impossible to achieve rapid and intelligent circuit disconnection, which may easily lead to safety risks and property losses, and cannot meet the user's usage needs.

[0059] Based on the above technical problems, the inventive concept of the present application is: how to provide a control solution for vehicle connected fuel tanks that can intelligently control the connectivity of multiple fuel tanks to meet the user's usage needs.

[0060] The embodiments of the present application provide a control method, device, vehicle and medium for connecting a vehicle to a fuel tank. The status of the fuel tank can be monitored in real time by a fuel tank control device arranged in the fuel tank. Whether an abnormality occurs in the connected fuel tank can be determined based on the real-time fuel pressure of the fuel tank and the real-time fuel flow rate at the connecting pipe joint of the fuel tank. The switching state of the solenoid valve corresponding to the connecting pipe of the fuel tank can be controlled based on this information, thereby realizing intelligent control of the connection of multiple fuel tanks, avoiding safety risks and property losses caused by fuel tank abnormalities, and meeting the user's usage needs.

[0061] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0062] Figure 1 This is a system architecture diagram of an embodiment of the present application, such as Figure 1 As shown, the vehicle includes a fuel tank 11, a fuel tank 12 (the present application can be applied to a plurality of fuel tanks connected, and the present embodiment takes the connection of two fuel tanks as an example for explanation), a bracket and a drawstring and other accessories 2 for installing the fuel tanks on the whole vehicle, a connecting pipe 3 between the fuel tanks, a vent valve 4 installed on the top of the fuel tank, a control device 5 of the fuel tank arranged at the bottom of the fuel tank, a display and control device and / or a remote terminal 6 of the vehicle, and related pipelines, wiring harnesses, etc. The vent valve 4 installed on the top of the fuel tank is kept open in a normal state to balance the pressure inside and outside the fuel tank. When the vehicle overturns or the fuel tank tilts, the vent valve is closed to prevent fuel from leaking from the vent valve. When the vehicle equipped with the connected fuel tank is running, the relevant oil pipe is continuously supplied with fuel under the action of the oil pump. The control device 5 of the fuel tank monitors the fuel pressure of the fuel tank, the fuel flow rate at the connecting pipe joint and other parameters in real time and performs calculation and judgment. When it is judged that the fuel tank is in a normal state, the control device 5 of the fuel tank controls the solenoid valve to open, the oil circuit is connected, and the relevant monitoring data is uploaded to the vehicle background database, and the normal working information is displayed on the display and control device and / or the remote terminal 6 of the vehicle. When the fuel tank condition is judged to be abnormal, the fuel tank control device 5 closes the corresponding solenoid valve, disconnects the oil circuit, and sends the abnormal information to the vehicle's display control device and / or remote terminal 6 to display the abnormal details, and uploads the relevant monitoring data to the vehicle's background database.

[0063] Figure 2 This is a flow chart of a method for controlling a vehicle connected to a fuel tank according to an embodiment of the present application. The vehicle may include at least two fuel tanks, each of which may be connected by a connecting pipe, and each fuel tank is provided with a fuel tank control device. This embodiment uses the fuel tank control device as the execution subject to illustrate the method for controlling a vehicle connected to a fuel tank. Figure 2 As shown, the control method for connecting the vehicle to the fuel tank may include the following steps:

[0064] S201: Acquire the real-time fuel pressure of the fuel tank and the real-time fuel flow rate at the connecting pipe joint of the fuel tank.

[0065] In this embodiment, the vehicle may include at least two fuel tanks, and the fuel tanks may be connected by a connecting pipe to form a connecting fuel tank, and the connecting pipe may be arranged at the bottom of the fuel tank. The position of the connecting pipe of each fuel tank may correspond to a solenoid valve to control whether the fuel tank is connected to other fuel tanks.

[0066] In this embodiment, the control device of the fuel tank can be set at the bottom of the fuel tank or at other positions of the fuel tank. As long as the control device can monitor the real-time fuel pressure and real-time fuel flow rate of the fuel tank in real time, no limitation is made here.

[0067] In this embodiment, the real-time fuel flow rate at the connecting pipe joint of the fuel tank may be the flow rate of the fuel when it flows through the fuel tank and the connecting pipe joint.

[0068] In this embodiment, the control device of the fuel tank can collect the real-time fuel pressure of the fuel tank and the real-time fuel flow rate at the connecting pipe joint of the fuel tank at a certain data collection period t.

[0069] S202: Determine the switch state of the solenoid valve corresponding to the connecting pipe of the fuel tank according to the real-time fuel pressure of the fuel tank and the real-time fuel flow rate at the connecting pipe joint of the fuel tank.

[0070] In this embodiment, the fuel pressure and the real-time fuel flow rate at the connecting pipe joint are important indicators for judging whether the working state of the fuel tank is normal. According to whether the working state of the fuel tank is normal, the switch state of the solenoid valve corresponding to the connecting pipe can be determined timely and accurately.

[0071] In this embodiment, if the working state of the fuel tank is abnormal, it is necessary to promptly control the solenoid valve corresponding to the connecting pipe of the fuel tank to close, so as to prevent the abnormal fuel tank from affecting other normal fuel tanks and abnormal fuel outflow.

[0072] In this embodiment, if the working state of the fuel tank is abnormal, an alarm can be promptly output through the vehicle's display and control device or the remote terminal to remind the user that the fuel tank is abnormal and corresponding measures need to be taken in time.

[0073] In this embodiment, each fuel tank of the vehicle is provided with a fuel tank control device, which can monitor the real-time fuel pressure of the fuel tank and the real-time fuel flow rate at the connecting pipe joint of the fuel tank; according to the real-time fuel pressure of the fuel tank and the real-time fuel flow rate at the connecting pipe joint of the fuel tank, it can be determined whether the connected fuel tank is abnormal, and the switch state of the solenoid valve corresponding to the connecting pipe of the fuel tank can be controlled accordingly. Through such a setting, the fuel tank control device can be used to monitor the fuel pressure, fuel flow rate and other information of the fuel tank in real time online, so as to quickly and accurately control the oil circuit on and off according to this information, realize intelligent control of the connection of multiple fuel tanks, avoid safety risks and property losses caused by fuel tank abnormalities, and meet the user's usage needs.

[0074] In a possible implementation, the above step S202 determines the switch state of the solenoid valve corresponding to the connecting pipe of the fuel tank according to the real-time fuel pressure of the fuel tank and the real-time fuel flow rate at the connecting pipe joint of the fuel tank, and may include:

[0075] S11: According to the real-time fuel pressure P of the fuel tank and a preset data collection period t, a fuel pressure change ∆P within the data collection period is determined.

[0076] S12: Determine the switch state of the solenoid valve corresponding to the connecting pipe of the fuel tank according to the fuel pressure change ∆P and the real-time fuel flow rate V at the connecting pipe joint of the fuel tank.

[0077] In this embodiment, the preset data collection period t can be flexibly set by those skilled in the art according to actual conditions, and no limitation is made here.

[0078] In this embodiment, the fuel pressure change can indicate whether the fuel content in the fuel tank has changed. If the fuel pressure change is greater than 0, it means that the fuel content in the fuel tank is decreasing; if the fuel pressure change is too large, it means that the fuel content in the fuel tank is decreasing abnormally.

[0079] In this embodiment, by using the fuel pressure change within a data collection cycle and the real-time fuel flow rate at the connecting pipe joint, it is possible to quickly and accurately determine whether the working state of the fuel tank is abnormal, and then determine the switching state of the solenoid valve corresponding to the connecting pipe of the fuel tank.

[0080] In a possible implementation, the above step S12 determines the switch state of the solenoid valve corresponding to the connecting pipe of the fuel tank according to the fuel pressure change and the real-time fuel flow rate at the connecting pipe joint of the fuel tank, and may include any one of the following:

[0081] A: When the fuel pressure change ∆P is less than or equal to the preset fuel pressure change threshold ∆Pmax, and greater than or equal to 0, and the real-time fuel flow rate V is less than or equal to the preset fuel flow rate threshold Vmax, it is determined that the solenoid valve corresponding to the connecting pipe of the fuel tank is in the open state.

[0082] B: When the fuel pressure change ∆P is equal to 0, and the real-time fuel flow rate V is equal to 0, and the fuel flow rate change ∆V within the data collection period is equal to 0, it is determined that the solenoid valve corresponding to the connecting pipe of the fuel tank is in a closed state.

[0083] C: When the fuel pressure variation ∆P is greater than a preset fuel pressure variation threshold ∆Pmax, and the real-time fuel flow rate V is greater than a preset fuel flow rate threshold Vmax, it is determined that the solenoid valve corresponding to the connecting pipe of the fuel tank is in a closed state.

[0084] D: When the fuel pressure variation ∆P is greater than a preset fuel pressure variation threshold ∆Pmax, and the real-time fuel flow rate is equal to 0, it is determined that the solenoid valve corresponding to the connecting pipe of the fuel tank is in a closed state.

[0085] In this embodiment, the fuel pressure change threshold ∆Pmax and the fuel flow rate threshold Vmax can be flexibly set by those skilled in the art according to actual conditions, and no limitation is made herein.

[0086] In this embodiment, the fuel flow rate variation ΔV within the data collection period can be calculated using the real-time fuel flow rates before and after the data collection period.

[0087] In this embodiment, if 0≤∆P≤∆Pmax, V<Vmax, it means that the fuel system is in normal working condition, the fuel content in the fuel tank changes normally, the solenoid valve input signal is 1, the solenoid valve is in the open state, and the vehicle large screen and remote terminal do not alarm.

[0088] If ∆P=0, ∆V=0 and V=0, it means that the fuel system is in shutdown state, the fuel content in the tank does not change, the solenoid valve input signal is 0, the solenoid valve is closed, and the vehicle large screen and remote terminal do not alarm.

[0089] If ∆P>∆Pmax, V>Vmax, it means that the fuel is abnormally reduced through the connecting pipe. The fuel system may be in an abnormal working state due to the reduction of fuel volume due to the rupture or detachment of the connecting pipe. The solenoid valve input signal is 0, the solenoid valve is closed, and the vehicle large screen and remote terminal alarm.

[0090] If ∆P>∆Pmax, V=0, it means that the fuel is decreasing abnormally, but the connecting pipe is normal. The fuel system may be in an abnormal working state due to factors such as fuel tank cracks or external oil theft, resulting in a decrease in fuel volume. The solenoid valve input signal is 0, the solenoid valve is closed, and the vehicle large screen and remote terminal sound an alarm.

[0091] In this embodiment, by comparing the fuel pressure change ∆P with the fuel pressure change threshold ∆Pmax, comparing the real-time fuel flow rate V with the fuel flow rate threshold Vmax, and the fuel flow rate change ∆V, it can be accurately determined whether the fuel tank is currently in a normal working state, a shutdown state, an abnormal state caused by a rupture or detachment of the connecting pipe, or an abnormal state caused by a crack in the fuel tank or external oil theft, and then accurately determine the switching state of the solenoid valve corresponding to the connecting pipe, so that the solenoid valve is opened when the fuel tank is working normally to ensure normal fuel supply, and the solenoid valve is closed in time when an abnormality occurs in the fuel tank to avoid affecting the normal fuel tank and abnormal fuel outflow, thereby avoiding safety risks and property losses caused by the abnormality of the fuel tank.

[0092] In a possible implementation, the method may further include:

[0093] When the fuel pressure change ∆P is greater than a preset fuel pressure change threshold ∆Pmax, and the real-time fuel flow rate V is greater than a preset fuel flow rate threshold Vmax, a first prompt message is output, and the first prompt message is used to prompt the user that the connecting pipe of the fuel tank is abnormal and causes fuel leakage.

[0094] In this embodiment, the control device of the fuel tank can output a first prompt message to the user through the vehicle's display and control device such as a large vehicle screen, and / or a remote terminal such as a mobile phone. The first prompt message can be one or more of text information, sound information, and image information.

[0095] In this embodiment, if ∆P>∆Pmax, V>Vmax, it means that the fuel is abnormally reduced through the connecting pipe, and the connecting pipe may be broken or fallen off. It is necessary to output the first prompt information in time to remind the user that the connecting pipe of the fuel tank is abnormal and causes fuel leakage, and corresponding measures need to be taken in time.

[0096] In a possible implementation, the method may further include:

[0097] When the fuel pressure change ∆P is greater than a preset fuel pressure change threshold ∆Pmax and the real-time fuel flow rate V is equal to 0, a second prompt message is output, and the second prompt message is used to prompt the user that the fuel tank is abnormal or external factors have caused fuel leakage.

[0098] In this embodiment, the control device of the fuel tank can output a second prompt information to the user through the vehicle's display and control device such as a large vehicle screen, and / or a remote terminal such as a mobile phone. The second prompt information can be one or more of text information, sound information, and image information.

[0099] In this embodiment, if ∆P>∆Pmax, V=0, it means that the fuel is decreasing abnormally, but the connecting pipe is normal, which may be caused by factors such as cracks in the fuel tank or external oil theft. It is necessary to output the second prompt information in time to remind the user that the fuel tank is abnormal or external factors have caused fuel leakage, and corresponding measures need to be taken in time.

[0100] In a possible implementation manner, when the solenoid valve corresponding to the connecting pipe of the oil tank is in a closed state, the method may further include:

[0101] The heating module of the control oil tank is in the off state.

[0102] In this embodiment, when the solenoid valve corresponding to the connecting pipe of the fuel tank is in a closed state, it means that the fuel tank is in a shutdown state or an abnormal state, and the fuel in the fuel tank does not need to be used. The heating module of the fuel tank can be controlled to be in a closed state and the fuel is not heated.

[0103] In a possible implementation manner, when the solenoid valve corresponding to the connecting pipe of the oil tank is in an open state, the method may further include:

[0104] S21: Obtain the real-time fuel temperature T of the fuel tank.

[0105] S22: Determine whether the real-time fuel temperature is less than a preset fuel temperature threshold Tmax.

[0106] S23: If the temperature is greater than or equal to the fuel temperature threshold Tmax, the heating module of the fuel tank is controlled to be in a closed state.

[0107] S24: If the temperature is less than the fuel temperature threshold Tmax, the heating module of the fuel tank is controlled to be in an on state.

[0108] In this embodiment, if T≥Tmax, it means that the current fuel temperature meets the working requirements of the fuel system, and the fuel does not need to be heated, and the heating module (heater, etc.) can be turned off. If T<Tmax, it means that the current fuel temperature cannot meet the working requirements of the fuel system, and the heating module of the fuel tank can be controlled to turn on to heat the fuel.

[0109] For example, Figure 3 Schematic diagram of the structure of the fuel tank control device according to an embodiment of the present application. Figure 3 As shown, the control device of the fuel tank may include a monitoring module 51, a control module 52, a heating module 53 and an alarm module 54. The monitoring module 51 can monitor the real-time fuel pressure and real-time fuel temperature of the fuel tank, as well as the real-time fuel flow rate at the connecting pipe joint of the fuel tank in real time, and send the real-time fuel pressure and real-time fuel flow rate to the control module 52, and send the real-time fuel temperature to the heating module 53. The control module 52 can determine the switch state of the solenoid valve corresponding to the connecting pipe of the fuel tank and the alarm signal according to the real-time fuel pressure and real-time fuel flow rate, and send the switch state of the solenoid valve to the heating module 53, and send the alarm signal to the alarm module 54. The heating module 53 can determine the switch state of the heating module of the fuel tank according to the switch state of the solenoid valve and the real-time fuel temperature. The alarm module 54 can send a prompt message to alarm through the display and control device of the vehicle and / or the remote terminal 6 according to the alarm signal.

[0110] In this embodiment, the fuel system needs to have a certain fluidity when it is working normally. Therefore, when the ambient temperature is too low, when the solenoid valve corresponding to the connecting pipe of the fuel tank is in an open state, the heating module of the fuel tank needs to be controlled to make the fuel temperature greater than or equal to the fuel temperature threshold.

[0111] The control method of the vehicle connected to the fuel tank of the present application is described below with a specific embodiment.

[0112] In a specific embodiment, a vehicle includes a fuel tank A and a fuel tank B, which are connected through a connecting pipe, and a fuel tank control device is installed at the bottom of each of the fuel tanks A and B. The fuel tank control device can control the fuel tank in which it is located. The specific control process of the connected fuel tanks is as follows:

[0113] In the first step, the control device of the fuel tank A / B obtains the real-time fuel pressure P of the fuel tank A / B, the real-time fuel flow rate V at the connecting pipe joint of the fuel tank A / B, and the real-time fuel temperature T of the fuel tank.

[0114] In the second step, the control device of the fuel tank A / B determines the fuel pressure change ∆P within the data collection period according to the real-time fuel pressure P of the fuel tank A / B and the preset data collection period t; and determines the fuel flow rate change ∆V within the data collection period according to the real-time fuel flow rate V at the connecting pipe joint of the fuel tank A / B and the preset data collection period t.

[0115] In the third step, the control device of the fuel tank A / B determines that 0≤∆P≤∆Pmax, V<Vmax, indicating that the fuel system is in normal working condition and the fuel content in the fuel tank changes normally, then the solenoid valve input signal is 1, so that the solenoid valve corresponding to the connecting pipe of the fuel tank A / B is in the open state.

[0116] In the fourth step, the control device of the fuel tank A / B determines that T<Tmax, and then controls the heating module of the fuel tank to be in an on state to heat the fuel.

[0117] Step 5. At a certain moment, the control device of fuel tank A / B determines that ∆P>∆Pmax, V>Vmax, indicating that the fuel is abnormally reduced through the connecting pipe, and the solenoid valve input signal is 0, so that the solenoid valve corresponding to the connecting pipe of fuel tank A / B is in a closed state.

[0118] In the sixth step, the control device of the fuel tank A / B outputs a first prompt information alarm to the user through the vehicle large screen and the remote terminal to remind the user that the connecting pipe of the fuel tank is abnormal and causes fuel leakage.

[0119] In the seventh step, the control device of the fuel tank A / B controls the heating module of the fuel tank to be in a closed state.
