[0052] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0053] The embodiments of the present application are only used to explain the present application and are not used to limit the scope of the present application. The present application is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present application.

[0054] At present, for the high-pressure fuel tank system, before controlling the fuel tank cap to open, the fuel tank needs to be depressurized first, and only when the pressure relief is successful can the fuel tank cap be controlled to open. During pressure relief, the pressure relief valve opens and the gas in the fuel tank is discharged. However, during pressure relief, abnormal conditions such as pressure relief valve failure and excessive pressure in the fuel tank will cause pressure relief failure, and the fuel tank cap cannot be opened normally when the pressure relief fails. In addition, in order to control costs, existing vehicles usually cancel the mechanical emergency cable of the fuel tank cap, and the fuel tank cap cannot be opened in an emergency when the pressure relief fails. In order to solve the above problems, the embodiments of the present application provide a fuel tank cap control method, device, storage medium and vehicle. The above-mentioned fuel tank cap control method, device, storage medium and vehicle are described in detail below.

[0055] First, refer to Figure 1 The fuel filler cap control method provided in the embodiment of the present application can be applied to a VIU (Vehicle Integration Unit, vehicle body domain controller) in a vehicle. The fuel filler cap control method includes:

[0056] Step 101, obtaining fuel filler cap control information.

[0057] The fuel filler cap control information includes at least a forced unlocking request and / or a normal unlocking request. The forced unlocking request is a request for instructing to open the fuel filler cap that is triggered when the user needs to force unlock the fuel filler cap in an abnormal situation, for example, when the pressure relief valve fails, the pressure in the fuel tank is too high, etc., resulting in a pressure relief failure. The normal unlocking request is a request for instructing to open the fuel filler cap in a normal situation. It should be noted that the fuel filler cap control information may also include a normal closing request, which is a request for instructing to close the fuel filler cap.

[0058] Step 102: When the fuel filler cap control information only includes a forced unlocking request, the fuel filler cap driving component is controlled to open the fuel filler cap according to the forced unlocking request.

[0059] The vehicle body domain controller is specifically connected to the fuel filler cap driver through a hard line. The fuel filler cap driver is used to drive the fuel filler cap to open or close, and the fuel filler cap driver may include a motor. When the fuel filler cap control information only includes a forced unlocking request, the fuel filler cap driver is directly controlled to open the fuel filler cap without performing pressure relief or judging whether the pressure relief is successful or not.

[0060] Step 103, when the fuel filler cap control information at least includes a forced unlocking request, a pressure relief request is sent to the engine management system, so that the engine management system controls the pressure relief valve to open according to the pressure relief request to relieve the pressure in the fuel tank.

[0061] The fuel tank is connected to the carbon canister through an exhaust pipe, and a pressure relief valve is provided on the exhaust pipe. The vehicle body domain controller is specifically connected to the engine management system (EMS) through a CAN (Controller Area Network) line, and the engine management system is specifically connected to the pressure relief valve through a hard line.

[0062] Step 104 : when the fuel filler cap control information includes a forced unlocking request and a normal unlocking request, controlling the fuel filler cap driving component to open the fuel filler cap according to the forced unlocking request.

[0063] Among them, the priority of forced unlocking is higher than that of normal unlocking. In normal unlocking, pressure relief is required first. After the first set time of pressure relief, it is determined whether the pressure relief is successful. The fuel filler cap is opened only when the pressure relief is successful, that is, it is necessary to wait for the pressure relief time in normal unlocking. In forced unlocking, there is no need to wait for pressure relief, but to open the fuel filler cap directly, and control the pressure relief valve to open while opening the fuel filler cap.

[0064] In the embodiment of the present application, when the pressure relief fails due to the failure of the pressure relief valve, the excessive pressure in the fuel tank, etc., and the user still needs to open the fuel filler cap, the fuel filler cap drive can be directly controlled to open the fuel filler cap based on the forced unlocking request, without the need to perform pressure relief and determine whether the pressure relief is successful or not, so that in the case of pressure relief failure, the fuel filler cap can still be forced to open, thereby meeting the user's emergency needs and avoiding the problem of being unable to open the fuel filler cap due to pressure relief failure. In addition, when a normal unlocking request and a forced unlocking request are received at the same time, the fuel filler cap drive is still directly controlled to open the fuel filler cap based on the forced unlocking request, without waiting for the pressure relief time during normal unlocking, thereby ensuring that the fuel filler cap can be quickly opened in an emergency. In addition, in the embodiment of the present application, the pressure relief valve is also controlled to open based on the obtained forced unlocking request to try to relieve pressure again, so that the risk can be reduced by trying to relieve pressure again.

[0065] It should be noted that even if the fuel tank is not depressurized, forcibly opening the fuel filler cap will not usually cause safety accidents or risks.

[0066] In an optional embodiment of the present application, referring to Figure 2 Step 101, obtaining the fuel filler cap control information includes: step 1011, in response to the user pressing the physical button, obtaining a forced unlocking request; step 1012, in response to the user touching the central control screen, obtaining a normal unlocking request; step 1013, determining the fuel filler cap control information according to the forced unlocking request and the normal unlocking request.

[0067] Among them, the physical button can be a physical button in the vehicle or a physical button on the vehicle key. The body domain controller specifically obtains the normal unlocking request through the in-vehicle infotainment system, and the in-vehicle infotainment system includes the central control screen. The central control screen is configured with soft keys, and the normal unlocking request can be triggered by touching the soft keys on the central control screen. When the central control screen fails, the vehicle is low on fuel, and the user needs to use the vehicle, the physical button can trigger forced unlocking, thereby opening the fuel filler cap. The need for the vehicle may be that the user needs to drive the vehicle to a repair shop for repair, or that the user has an emergency that needs to be handled.

[0068] The existing method of unlocking the fuel filler cap is usually to unlock it by clicking the unlock soft button configured on the central control screen. However, when the central control screen fails, the fuel filler cap cannot be unlocked. In this embodiment, the forced unlocking can be triggered by a physical button, thereby opening the fuel filler cap, avoiding the fuel filler cap being unable to be opened due to a central control screen failure.

[0069] In an optional embodiment of the present application, referring to Figure 3Step 102, when the fuel filler cap control information includes only a forced unlocking request, controlling the fuel filler cap driving member to open the fuel filler cap according to the forced unlocking request, includes:

[0070] Step 1021, when the fuel filler cap control information only includes a forced unlocking request, converting the forced unlocking request into a forced unlocking service signal through the basic service layer in the SOA architecture, and transmitting the forced unlocking service signal to the application layer in the SOA architecture;

[0071] Step 1022, the application layer outputs a forced opening signal to the fuel filler cap enhancement service in the enhancement service layer in the SOA architecture according to the forced unlocking service signal;

[0072] Step 1023, the fuel filler cap enhancement service outputs a driver start signal to the driver atomic service in the atomic service layer in the SOA architecture according to the forced opening signal;

[0073] Step 1024 , the driver atomic service calls the driver abstraction in the device abstraction layer in the SOA architecture to control the fuel filler cap driver to open the fuel filler cap.

[0074] Among them, refer to Figure 5 The vehicle body domain controller is configured with a SOA architecture, which includes a basic service layer, an application layer, an enhanced service layer, an atomic service layer and a device abstraction layer. The forced unlocking request is a CAN signal, and the basic service layer is mainly used to provide services such as CAN signal conversion to service signal, service signal conversion to CAN signal, etc. The application layer is used to open up to the outside world to achieve personalized customization and support users to flexibly arrange scenes. The device abstraction layer is used to abstract the device, and the atomic service layer is used to shield the impact of changes in the device abstraction layer on the enhanced service layer. In this embodiment, the application layer can be open to the outside world to achieve personalized customization, so that users can flexibly arrange scenes. The device abstraction layer abstracts the device and provides a standardized device access interface to the atomic service layer, so as to shield the differences in the functions of different devices and reduce customization.

[0075] The basic service layer will correspond the CAN signal to the service interface according to the preset correspondence rules, for example, one-to-one correspondence between different CAN signals and service interfaces, or correspondence between multiple CAN signals and one service interface, and convert the CAN signal into a service signal that can be processed by the corresponding service interface, and then transmit the service signal to the application layer through the service interface. The basic service layer is specifically used to convert the forced unlocking request into a forced unlocking service signal, and transmit the forced unlocking service signal to the application layer through the service interface. After receiving the forced unlocking service signal, the application layer will confirm whether to execute the forced unlocking service signal based on other scene information of the vehicle, for example, whether the vehicle is in a stopped state. If it is confirmed that the forced unlocking service signal will be executed, a forced opening signal will be output to the fuel filler cap enhanced service.

[0076] The driver atomic service in the atomic service layer is the smallest service unit in the SOA architecture. The driver atomic service can encapsulate control parameters, such as the driving direction and driving time of the fuel filler cap driver. When the driver atomic service calls the driver abstraction to control the fuel filler cap driver to open the fuel filler cap, the driver abstraction is called according to the control parameters to control the fuel filler cap driver to open the fuel filler cap.

[0077] In an optional embodiment of the present application, step 103, when the fuel filler cap control information includes at least a forced unlocking request, sends a pressure relief request to the engine management system, including: when the fuel filler cap enhanced service receives a forced opening signal, outputs a pressure relief service signal to the basic service layer; converts the pressure relief service signal into a pressure relief request through the basic service layer; wakes up the engine management system, and sends a pressure relief request to the engine management system.

[0078] In this embodiment, the main function of the basic service layer is to process the service signal transmitted by the upper layer service and convert it into a signal that can be recognized by the device or system. The pressure relief request is specifically a CAN signal, and the converted pressure relief request needs to be executed by the vehicle's engine management system. The basic service layer will first wake up the engine management system to ensure that the engine management system is in working condition and can receive and process subsequent pressure relief requests. Once the engine management system is awakened, the basic service layer will send the generated pressure relief request to the engine management system. After receiving the pressure relief request, the engine management system will control the pressure relief valve to open. The SOA architecture adopts a standardized service interface, and the basic service layer and the engine management system can communicate through a standardized interface to be compatible with different types of engine management systems.

[0079] In an optional embodiment of the present application, the normal unlocking request includes a normal pressure relief service signal; step 103, when the fuel filler cap control information includes a forced unlocking request and a normal unlocking request, controlling the fuel filler cap driving member to open the fuel filler cap according to the forced unlocking request, includes:

[0080] When the fuel filler cap control information includes a forced unlocking request and a normal pressure relief service signal, the forced unlocking request is converted into a forced unlocking service signal through the basic service layer in the SOA architecture, and the forced unlocking service signal is transmitted to the application layer in the SOA architecture;

[0081] The application layer outputs a forced opening signal to the fuel filler cap enhancement service in the enhancement service layer in the SOA architecture according to the forced unlocking service signal;

[0082] The fuel filler cap enhancement service receives the normal pressure relief service signal, performs priority arbitration between the forced opening signal and the normal pressure relief service signal, and outputs the driver start signal to the driver atomic service in the atomic service layer in the SOA architecture according to the forced opening signal having the highest priority between the two;

[0083] The driver atomic service calls the driver abstraction in the device abstraction layer in the SOA architecture to control the fuel filler cap driver to open the fuel filler cap.

[0084] Among them, the fuel filler cap enhancement service stores a preset priority order, and the priority of the forced opening signal is greater than the priority of the normal pressure relief service signal. When the fuel filler cap enhancement service receives the normal pressure relief service signal and the forced opening signal at the same time, it will perform priority arbitration on the forced opening signal and the normal pressure relief service signal. In this embodiment, the fuel filler cap enhancement service mainly plays an arbitration role. When more than two signals are received at the same time, the fuel filler cap enhancement service will perform priority arbitration on the signals according to the preset priority rules to ensure that in an emergency, a higher priority operation can be performed first.

[0085] In an optional embodiment of the present application, step 1011, in response to a user pressing a physical button, obtaining a forced unlocking request, includes: in response to a user pressing a physical button on a vehicle key, obtaining a forced unlocking request through a key controller.

[0086] The vehicle key is used to respond to the user's pressing operation on the physical button on the vehicle key, send a refueling unlock signal to the key controller, and the key controller outputs a forced unlock request when receiving the refueling unlock signal. The vehicle key is wirelessly connected to the key controller, and the key controller is connected to the vehicle body domain control line via a CAN line. The wireless connection between the vehicle key and the key controller can be Bluetooth connection, connection via a radio frequency protocol, etc.

[0087] The user can trigger forced unlocking by pressing the unlock physical button and the tailgate opening physical button on the vehicle key at the same time and continuously for a second set time, and the second set time can be set according to actual needs, for example, it can be set to 3 seconds, 4 seconds, 5 seconds, 8 seconds, 10 seconds, etc. In this embodiment, when refueling is required and pressure relief fails or the central control screen fails, the user can directly trigger forced unlocking by pressing the physical button on the vehicle key outside the vehicle without entering the vehicle to operate, which can improve the convenience of user operation.

[0088] In an optional embodiment of the present application, referring to Figure 4 , step 101, after obtaining the fuel filler cap control information, also includes: step 105, when the fuel filler cap control information only includes a normal unlocking request, sending a pressure relief request to the engine management system, so that the engine management system controls the pressure relief valve to open according to the pressure relief request to relieve the pressure of the fuel tank, and when the pressure relief is successful, controls the fuel filler cap drive to open the fuel filler cap.

[0089] Among them, after the pressure relief valve is continuously opened for the first set time, if the pressure in the fuel tank is less than or equal to the unlocking pressure, it means that the pressure relief is successful. The first set time can be set according to actual needs, for example, it can be set to 10 seconds, 13 seconds, 15 seconds, 18 seconds, 20 seconds, etc. Specifically, after sending the pressure relief request to the engine management system, if the pressure relief is successful, before controlling the fuel filler cap drive to open the fuel filler cap, it also includes: after the pressure relief valve is continuously opened for the second set time, judging whether the pressure in the fuel tank is less than or equal to the unlocking pressure, if so, the pressure relief is successful. A pressure sensor is provided in the fuel tank, and the pressure in the fuel tank can be determined by the pressure sensor. In the embodiment of the present application, when the fuel filler cap is normally unlocked, pressure relief will be performed first, and the fuel filler cap will only be opened when the pressure relief is successful, so as to ensure that under normal use, the pressure in the fuel tank has been reduced to a safe range when the fuel filler cap is opened.
