Description

Technical Field

[0001] This application relates to the field of vehicle refueling control technology, and in particular to a high-pressure fuel tank control method, controller and vehicle. Background Technology

[0002] In hybrid vehicles, if the pressure inside the high-pressure fuel tank exceeds the safety design range before opening the tank cap during refueling, it could cause injury to people and lead to fuel vapor leakage, damaging the environment. Therefore, it is necessary to control the pressure inside the high-pressure fuel tank.

[0003] However, existing technologies cannot achieve precise control of the high-pressure fuel tank according to the refueling scenario. For example, if refueling is stopped in the middle of the process (such as due to user-initiated stoppage, fuel nozzle malfunction, etc.), the high-pressure fuel tank cannot be controlled.

[0004] It can be seen that existing technologies cannot intelligently control the high-pressure oil tank, thus affecting the overall control level of the vehicle. Summary of the Invention

[0005] To address the problems existing in the prior art, embodiments of the present invention provide a method, controller, and vehicle for controlling a high-pressure fuel tank, thereby solving or partially solving the technical problem that the prior art cannot intelligently control the high-pressure fuel tank, thus affecting the overall control level of the vehicle.

[0016] If it is determined that the first duration is less than the first duration threshold, the pressure relief valve of the high-pressure oil tank is closed, and the filler cap is kept closed.

[0017] The method in the above scheme further includes:

[0018] If the refueling operation information is not received at the first moment, then the first current pressure of the high-pressure oil tank is obtained;

[0019] If it is determined that the first current pressure is less than the preset pressure threshold, then the filler cap is opened.

[0020] In the above scheme, after the control filler cap is opened, the method further includes:

[0021] If no oil gun is detected inserted into the filler port, and it is determined that the opening duration of the filler port cover is greater than the second duration threshold, then the pressure relief valve of the high-pressure oil tank is controlled to close, and the filler port cover is controlled to close.

[0022] The method in the above scheme further includes:

[0023] If it is determined that the first current pressure is greater than the pressure threshold, then the second current pressure of the high-pressure oil tank at the second moment is obtained; the second moment is greater than the first moment.

[0024] If it is determined that the second current pressure is greater than the pressure threshold, the pressure relief valve of the high-pressure oil tank is closed, and the filler cap is kept closed.

[0025] A second aspect of the present invention provides a high-pressure oil tank controller, the controller comprising:

[0026] The first control unit is used to adjust the current state of the vehicle to the parking state and control the high-pressure fuel tank to start depressurizing when it is determined that the vehicle intends to refuel.

[0027] The second control unit is configured to control the high-pressure fuel tank accordingly if it receives refueling operation information sent by the user and determines that the refueling intention has been cancelled based on the refueling operation information.

[0030] If it is determined that the first duration is less than the first duration threshold, then the pressure relief valve of the high-pressure oil tank is closed, and the filler cap is closed.

[0031] A third aspect of the invention provides a vehicle comprising the controller described in any one of the second aspects.

[0039] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0040] This invention provides a high-pressure oil tank control method, applied in a controller, which can be an Electronic Control Unit (ECU), such as... Figure 1 As shown, the method mainly includes the following steps:

[0041] S110: If it is determined that the vehicle intends to refuel, the vehicle's current status is adjusted to the parked state, and the high-pressure fuel tank is depressurized.

[0042] This embodiment can intelligently identify whether a vehicle intends to refuel. If it is determined that the vehicle intends to refuel, it means that the vehicle is very likely to need to refuel, and some preparatory work will be performed in advance, such as parking and controlling the pressure relief of the high-pressure fuel tank.

[0043] In one implementation, determining that a vehicle intends to refuel includes:

[0044] If the vehicle's current speed is less than a preset speed threshold, and the user's command to open the fuel filler cap is received, it is determined that the vehicle intends to refuel. The speed threshold can be 2-3 km / h.

[0045] Users can send commands to the controller to open the fuel filler cap via physical buttons, virtual buttons on the central control screen, voice control, remote key, or remote APP.

[0046] Physical buttons can be located on one side of the central control screen, on the side of the instrument panel, or in other places convenient for the driver to operate; there are no restrictions.

[0047] The virtual buttons on the central control screen are located within the screen itself, which also has the function of receiving voice commands. Therefore, users can send commands to open the fuel filler cap via virtual buttons or voice.

[0048] The central control screen features virtual buttons for opening and closing, as well as voice prompts. Users can directly click the "Open" virtual button on the central control screen to send a command to the controller to open the fuel filler cap.

[0049] Alternatively, press and hold the voice icon, then input the voice command "Open the fuel filler cap". When you release the voice icon, a voice command to open the fuel filler cap will be sent to the controller.

[0050] Alternatively, you can wake up the controller using the voice wake-up function and directly output the command "Open the fuel filler cap" to the controller.

[0051] A corresponding physical button can also be set on the remote key, allowing users to send a command to open the fuel filler cap via the physical button on the remote key.

[0052] Alternatively, users can download a corresponding app on their mobile devices to remotely send commands to open the fuel filler cap. The mobile device and controller can be pre-connected via a network, such as 5G or Bluetooth, to enable remote commands to be sent. The mobile device can include at least one of the following: a smartphone, a tablet, or a wearable device.

[0053] This embodiment can also determine whether a vehicle intends to refuel using other methods, as follows:

[0054] The first method:

[0055] Determine the effective refueling range of the gas station; if the vehicle is determined to be within the effective refueling range, obtain the vehicle's fuel tank level and / or current speed; determine whether the vehicle intends to refuel based on the vehicle's fuel tank level and / or current speed.

[0056] Specifically, firstly, the center point of the gas station is identified using a high-precision map; then, the area formed by taking the center point of the gas station as the center and a preset distance as the radius is determined as the effective refueling range.

[0057] It should be noted that, since the gas station area is relatively large, the center point of the gas station mentioned in this embodiment refers to the center point of the refueling area, that is, the center point of the area where the refueling piles are located.

[0058] Then, you can refer to Figure 2 A circular area 21 is formed with point O as the center and a preset distance R1 as the radius. This circular area 21 should include all the gas stations within the gas station, and this circular area is the effective refueling range. The preset distance can be 3 to 4 meters, preferably 3.5 meters.

[0059] If the vehicle is determined to be within the effective refueling range, and the fuel level in the tank is low and / or the current vehicle speed is low, it indicates that the vehicle is likely intending to refuel. Therefore, it is necessary to further consider the fuel level in the tank and / or the current vehicle speed to determine whether the vehicle intends to refuel.

[0060] For example, if it is determined that the current vehicle speed is less than or equal to the first vehicle speed threshold, then it is further determined whether the fuel level in the tank is less than or equal to the fuel level threshold; if it is determined that the fuel level in the tank is less than or equal to the fuel level threshold, then it is determined that the vehicle intends to refuel.

[0061] For example, if it is determined that the current vehicle speed is greater than a first speed threshold but less than or equal to a second speed threshold, and it is determined that a user's instruction to open the fuel filler cap has been received, then it is determined that the vehicle intends to refuel. The second speed threshold can be 5–10 km / h.

[0062] The second method:

[0063] If the vehicle is determined to be within the range of a refueling station and the current refueling nozzle is determined to be idle, the system retrieves the user's vehicle operation information; based on this information, it determines whether the vehicle intends to refuel. The range of a refueling station includes an area containing at least one refueling station; please refer to [reference needed] for details. Figure 3 Marker 31 in the text.

[0064] The operation information in this embodiment may include at least one of the following: opening operation information for the fuel filler cap, power-off operation information for the vehicle, unfastening operation information for the seat belt, and opening operation information for the vehicle door.

[0065] In one implementation, determining that the vehicle intends to refuel based on operational information includes:

[0066] If it is confirmed that a user's command to open the fuel filler cap has been received; or,

[0067] If it is confirmed that a vehicle power-off command sent by the user has been received; or,

[0068] If the system receives a message that the driver's seatbelt has been unbuckled and a message that the driver's side door has been opened, then it is determined that the vehicle intends to refuel.

[0069] When it is determined that the vehicle intends to refuel, as mentioned above, in order to improve the safety of the refueling process, this embodiment needs to adjust the vehicle's current state to the parked state and control the high-pressure fuel tank to start depressurizing.

[0070] In one implementation, adjusting the vehicle's current state to a parked state includes:

[0071] If the vehicle is determined to be a gasoline-powered vehicle, shift the vehicle to the parking position and shut off the engine.

[0072] If the vehicle is determined to be a hybrid vehicle, shift the vehicle to the parking position, shut off the engine, and switch the vehicle's powertrain to an inactive state.

[0073] Specifically, if the vehicle is a gasoline-powered vehicle, the power source includes the engine, so it is necessary to obtain the engine status of the vehicle. If the engine status is on, it is necessary to control the engine to shut down.

[0074] If the vehicle is a hybrid vehicle, the power source includes an engine and a generator, so it is necessary to obtain the status of the entire power system. If the power system is in an active state, it is necessary to control the power system to exit the active state.

[0075] Generally, if the pressure in the high-pressure fuel tank is too high, it may cause harm to the human body when the tank cap is opened, and it may also cause fuel vapor to overflow, damaging the environment. Therefore, in this embodiment, after the vehicle is adjusted to the parked state, it is necessary to control the opening of the pressure relief valve of the high-pressure fuel tank to release the pressure in the high-pressure fuel tank and further improve the safety of the refueling process.

[0076] S111, if a refueling operation message sent by the user is received, and it is determined from the refueling operation message that the refueling intention has been cancelled, then the high-pressure fuel tank is controlled accordingly based on the refueling operation message.

[0077] During or after the depressurization process, a refueling operation message (such as a refueling cancellation instruction) may be received from the user. If it is determined from the refueling operation message that the refueling intention has been cancelled, the high-pressure oil tank needs to be controlled according to the refueling operation message to prevent the pressure relief valve of the high-pressure oil tank from remaining open, which would cause oil and gas to overflow and pollute the environment.

[0078] In one embodiment, controlling the high-pressure oil tank based on refueling operation information includes:

[0079] If a refueling operation message is received at the first moment, it is determined whether the first duration is less than a preset first duration threshold; the first duration is the time from the moment when the vehicle's refueling intention is determined to the first moment.

[0080] If it is determined that the first duration is less than the first duration threshold, the pressure relief valve of the high-pressure oil tank is closed, and the filler cap is kept closed.

[0081] In this embodiment, the first duration threshold can be 13 to 17 seconds, preferably 15 seconds; the first duration can also be set according to the actual situation, and is not limited here.

[0082] The first moment can be understood as any moment within 15 seconds after it is determined that the vehicle intends to refuel, such as the 10th second.

[0083] Specifically, if the following situations occur while a user is about to refuel, the user may actively send a refueling cancellation command:

[0084] The user has an urgent matter to attend to; or...

[0085] The user decides not to refuel at the last minute; or...

[0086] There was a malfunction at the refueling station; or,

[0087] Or the gas station is out of fuel.

[0088] If the vehicle has already begun preparations for refueling, such as opening the pressure relief valve to depressurize the high-pressure fuel tank, and then receives a cancellation command from the user, current technology cannot perform any actions on the high-pressure fuel tank in this situation. However, it's understandable that since the pressure relief valve is already open, if the vehicle drives away directly, the valve will remain open, leading to fuel vapor leakage, environmental pollution, and safety hazards.

[0089] Based on this, this embodiment starts timing from the moment the vehicle's refueling intention is determined. If a user-sent cancellation refueling command (refueling operation information) is received within a first time threshold, the pressure relief valve of the high-pressure fuel tank is closed, and the fuel filler cap remains closed (the fuel filler cap remains closed until pressure relief is confirmed to be successful), thus preventing the refueling action from being performed. This effectively avoids fuel vapor leakage and environmental pollution, while also improving vehicle safety.

[0090] In one implementation, the method further includes:

[0091] If the refueling operation information is not received at the first moment, then the first current pressure of the high-pressure oil tank is obtained;

[0092] If it is determined that the first current pressure is less than the preset pressure threshold, then the filler cap is opened.

[0093] In one embodiment, after the control filler cap is opened, the method further includes:

[0094] If no oil gun is detected inserted into the filler port, and it is determined that the opening duration of the filler port cover is greater than the second duration threshold, then the pressure relief valve of the high-pressure oil tank is controlled to close, and the filler port cover is controlled to close.

[0095] The second duration threshold can be 12 to 17 minutes, preferably 15 minutes; it can also be set based on actual conditions, and there is no restriction here.

[0096] Specifically, if no cancellation command is received from the user within the first time threshold, it means that the vehicle still intends to refuel. In order to ensure refueling safety, it is necessary to further detect the first current pressure of the high-pressure fuel tank. If the first current pressure is less than the pressure threshold, it means that the pressure relief is successful and the refueling cap can be opened to allow refueling.

[0097] If, after opening the fuel filler cap, refueling is not possible at fuel station A (e.g., due to a malfunction at the fuel nozzle, no fuel at fuel station A, insufficient distance between the vehicle and the fuel nozzle at fuel station A, or the vehicle being parked in the wrong location), the vehicle needs to be moved slightly to fuel station B with the cap still open. In existing technology, if the high-pressure fuel tank pressure relief valve is closed during the movement from fuel station A to fuel station B, the user needs to resend the refueling command upon arrival at fuel station B. Otherwise, even if the fuel filler cap is open at this point, the pressure relief valve will be closed, causing the fuel nozzle to skip and preventing refueling.

[0098] In order to avoid the above situation and improve the overall control level and intelligence of the vehicle, this embodiment sets an appropriate second time threshold. If the fuel nozzle is not detected to be inserted into the fuel filler port and it is determined that the opening time of the fuel filler cap is greater than the second time threshold, the pressure relief valve of the high-pressure fuel tank will be closed and the fuel filler cap will be closed.

[0099] Understandably, when a vehicle needs to move from gas station A to gas station B, the time generally will not exceed the second time threshold. Therefore, this embodiment will not control the pressure relief valve of the high-pressure fuel tank to close, ensuring that when the vehicle moves to gas station B, it can refuel smoothly without the user having to send a refueling command (fuel cap opening command) again.

[0100] In practical applications, the following situations may also occur:

[0101] If no cancellation refueling command is received from the user within the first time threshold, but the first current pressure of the high-pressure oil tank is determined to be not less than the preset pressure threshold, it indicates that the pressure relief was unsuccessful and the pressure relief system may be faulty.

[0102] To further verify whether there is a fault in the pressure relief system, it is necessary to continue to test the pressure of the high-pressure fuel tank. If the pressure of the high-pressure fuel tank is always greater than the pressure threshold, it indicates that there is indeed a fault in the pressure relief system, and the vehicle is not suitable for refueling at this time.

[0103] In one implementation, the method further includes:

[0104] If it is determined that the first current pressure is greater than the pressure threshold, then the second current pressure of the high-pressure oil tank at the second moment is obtained; the second moment is greater than the first moment.

[0105] If it is determined that the second current pressure is greater than the pressure threshold, then the pressure relief valve of the high-pressure oil tank is closed, and the filler cap is closed.

[0106] The second moment can be any moment after 15 seconds from when the vehicle's intention to refuel is determined, such as the 25th second after the vehicle's intention to refuel is determined.

[0107] In other words, if the first current pressure is determined to be greater than the pressure threshold at the first moment, and the second current pressure is determined to still be greater than the pressure threshold at the second moment, it indicates that the vehicle's pressure relief system is indeed malfunctioning. In this case, refueling is not allowed, and the pressure relief valve and the filler cap should be closed to prevent fuel leakage during vehicle operation and improve driving safety.

[0108] In one implementation, this embodiment can determine whether refueling can be performed by checking the state of the refueling permission threshold. If refueling is allowed, a high level is output. At this time, the refueling permission threshold is 1. The high level triggers the refueling port cover to open, and refueling can be performed by inserting the nozzle.

[0109] If refueling is not allowed, a low level is output. At this time, the refueling allowance threshold is 0, and the low level triggers the refueling port cover to remain closed.

[0110] After refueling is complete, the method also includes:

[0111] Determine if the filler cap meets the closing conditions. If any of the following closing conditions are met, then control the filler cap to close; the closing conditions include:

[0112] Confirm that the fuel filler cap is not closed and the current vehicle speed is greater than the third speed threshold; the third speed threshold can be 15-25 km / h; or,

[0113] Determine that the distance between the vehicle and the center point of the gas station is greater than a distance threshold; or,

[0114] Confirm that the user's instruction to close the fuel filler cap has been received.

[0115] For example, refer to Figure 2 In this embodiment, a distance threshold R2 is preset. If the vehicle is stationary, and the reference distance S between the current position and the center point of the gas station is greater than R2, it means that the vehicle is outside the effective refueling range and outside the gas station, and the refueling cap will be closed.

[0116] If the vehicle is constantly in motion, when the reference distance S is detected to gradually increase until it exceeds R2, it indicates that the vehicle is leaving the gas station, and the gas filler cap will be closed.

[0117] Similarly, users can also send a command to the controller to close the fuel filler cap via physical buttons, virtual buttons on the central control screen, voice control, remote key, or remote APP.

[0118] Physical buttons can be located on one side of the central control screen, on the side of the instrument panel, or in other places convenient for the driver to operate; there are no restrictions.

[0119] The virtual buttons on the central control screen are located within the screen itself, and the screen also has voice command reception capabilities. Therefore, users can send commands to close the fuel filler cap via virtual buttons or voice. The central control screen features virtual buttons for opening and closing, as well as voice indicators. Users can directly click the "Close" virtual button on the central control screen to send the fuel filler cap closing command to the controller.

[0120] Alternatively, press and hold the voice icon and enter the voice command "Close the fuel filler cap". When you release the voice icon, a voice command to close the fuel filler cap will be sent to the controller.

[0121] Alternatively, you can wake up the controller using the voice wake-up function and directly output the command "Close the fuel filler cap" to the controller.

[0122] A corresponding physical button can also be set on the remote key, allowing users to send a command to close the fuel filler cap via the physical button on the remote key.

[0123] Alternatively, users can download a corresponding app on their mobile devices and use the app to send commands to close the fuel filler cap. The mobile device and controller can be pre-connected via a network, such as 5G or Bluetooth, to remotely send the fuel filler cap closing command to the controller. The mobile device can include at least one of the following: a mobile phone, a tablet, or a wearable device.

[0124] Thus, in this embodiment, if refueling operation information is received during the refueling process, and it is determined from the refueling operation information that the refueling intention has been cancelled, the pressure relief valve and the refueling cap are precisely controlled according to the refueling operation information. This ensures vehicle safety during refueling while flexibly meeting various application scenarios, minimizing refueling dangers and hazards, improving the overall control level of the vehicle, and thereby enhancing the vehicle's ability to adapt to various refueling environments.

[0125] Based on the same inventive concept as in the foregoing embodiments, this embodiment also provides a high-pressure oil tank controller, which can be an ECU, such as... Figure 4 As shown, the controller includes:

[0126] The first control unit 41 is used to adjust the current state of the vehicle to the parking state and control the high-pressure fuel tank to start depressurizing when it is determined that the vehicle intends to refuel.

[0127] The second control unit 42 is configured to control the high-pressure fuel tank accordingly if it receives refueling operation information sent by the user and determines that the refueling intention has been cancelled based on the refueling operation information.

[0128] In one embodiment, the refueling operation information includes: canceling the refueling command; the second control unit 42 is specifically used for:

[0129] If the refueling operation information is received at the first moment, it is determined whether the first duration is less than a preset first duration threshold; the first duration is the duration from the moment when the vehicle is determined to have the intention to refuel to the first moment.

[0130] If it is determined that the first duration is less than the first duration threshold, then the pressure relief valve of the high-pressure oil tank is closed, and the filler cap is closed.
