In addition, if a fault occurs during the process of controlling the fuel filler cap to be unlocked, the specific reason why the fuel filler cap cannot be opened can be determined based on whether the gear information and engine start-stop information meet the preset pressure relief conditions and the target refueling signal.

[0024] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0025] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0026] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0027] The term "multiple" as used in this application refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0028] Figure 1 A schematic flow chart of S210-S240 of a vehicle fuel filling control method provided in an embodiment of the present application is shown, combined with Figure 1As shown, this embodiment provides a vehicle fuel filling control method, which includes steps S210 to S240 and is executed by the vehicle terminal, and is described in detail as follows:

[0029] Step S210: In response to the received refueling request instruction, obtain the vehicle's gear information and engine start / stop information.

[0030] In an exemplary embodiment of the present application, after the gear information of the vehicle is obtained, it can be determined whether the vehicle is in the "P" gear or not according to the gear information, thereby determining whether the vehicle is in the parking state.

[0031] In an exemplary embodiment of the present application, after the engine start-stop information is obtained, it can be determined whether the engine is in a stopped state or a working state according to the engine start-stop information, thereby determining whether the vehicle is turned off.

[0032] Step S220: If the gear position information and the engine start / stop information both meet the preset pressure relief conditions, the fuel tank of the vehicle is controlled to relieve pressure, and the pressure relief information of the fuel tank is obtained.

[0033] In an exemplary embodiment of the present application, controlling the vehicle's fuel tank to release pressure includes controlling the high-pressure fuel tank isolation valve to open. The preset pressure relief condition is: the vehicle is in "P" gear and the engine is in a stopped state. In other words, the gear information and the engine start-stop information both meet the preset pressure relief condition, which means: the gear information is "P" gear and the engine is in a stopped state.

[0034] For example, when the vehicle terminal receives a refueling request from the user, it can first obtain the vehicle's gear information. If the vehicle's gear is determined to be "P" gear according to the gear information, the vehicle's engine start-stop information is obtained. If the engine is determined to be in a stopped state according to the vehicle's engine start-stop information, it is determined that the gear information and the engine start-stop information both meet the preset pressure relief condition. If the vehicle's gear is determined to be non-"P" gear according to the gear information, it is determined that the gear information does not meet the preset pressure relief condition, and a prompt message of "parking and shifting to "P" gear" is generated at the same time; if the vehicle's gear is determined to be "P" gear according to the gear information, the vehicle's engine start-stop information is obtained. If the engine is determined to be in a working state according to the vehicle's engine start-stop information, the engine is controlled to stop to meet the preset pressure relief condition.

[0035] In an exemplary embodiment of the present application, the pressure relief information includes the duration of the fuel tank pressure relief and the pressure in the fuel tank, and then it can be determined through the pressure relief information whether the pressure in the fuel tank has reached a state where the fuel filler cap can be unlocked.

[0036] In an exemplary embodiment of the present application, Figure 2A schematic flow chart of S221-S223 of a vehicle fuel filling control method provided in an embodiment of the present application is shown, combined with Figure 2 As shown, the method for controlling the oil tank of a vehicle to release pressure includes steps S221 to S223, which are described in detail as follows:

[0037] Step S221: Obtain the remaining fuel amount in the fuel tank.

[0038] In an exemplary embodiment of the present application, Figure 3 A schematic flow chart of steps S2211-S2213 of a vehicle fuel filling control method provided in an embodiment of the present application is shown, combined with Figure 3 As shown, the vehicle includes an oil level sensor for collecting the remaining oil level value, and the method for obtaining the remaining oil level value of the fuel tank includes steps S2211 to S2213, which are described in detail as follows:

[0039] Step S2211: Obtain the resistance value signal and voltage signal of the oil level sensor, wherein the resistance value signal is the original resistance value signal of the oil level sensor.

[0040] Step S2212: determining a first remaining fuel reference value based on the resistance signal and determining a second remaining fuel reference value based on the voltage signal.

[0041] For example, a first remaining fuel reference value may be generated by filtering and calculating the resistance value signal of the fuel level sensor; and a second remaining fuel reference value may be generated by filtering and calculating the voltage signal of the fuel level sensor.

[0042] Step S2213: If the absolute value of the difference between the first fuel level remaining reference value and the second fuel level remaining reference value is less than or equal to the preset fuel level error value within the second preset time period, the average value of the first fuel level remaining reference value and the second fuel level remaining reference value is determined as the remaining fuel level value, so as to obtain an accurate remaining fuel level value so as to facilitate the smooth unlocking of the fuel filler cap.

[0043] For example, the preset oil error value is a (a>0), and the absolute value of the difference between the first oil remaining reference value and the second oil remaining reference value is b. If b>a, it means that the error between the first oil remaining reference value and the second oil remaining reference value is large. At this time, it means that the oil sensor may have a fault when collecting the oil remaining value, and then the oil sensor fault information can be generated so that the user can find the reason why the fuel filler cap cannot be opened as soon as possible. If b<a, it means that there is almost no error between the collected first oil remaining reference value and the second oil remaining reference value. At this time, in order to further eliminate the error, the average of the first oil remaining reference value and the second oil remaining reference value can be determined as the remaining oil value.

[0044] Step S222: Determine a target pressure relief strategy based on the magnitude relationship between the remaining fuel value and the remaining fuel threshold, the target pressure relief strategy being a first pressure relief strategy of only opening the rollover valve or a second pressure relief strategy of opening both the rollover valve and the refueling limit valve. The remaining fuel threshold can be obtained by calibration.

[0045] In an exemplary embodiment of the present application, if the remaining oil value is greater than the remaining oil threshold, it means that the amount of oil in the fuel tank is relatively large. At this time, the first pressure relief strategy can be used as the target pressure relief strategy to release pressure by only opening the rollover valve. If the remaining oil value is less than the remaining oil threshold, it means that the amount of oil in the fuel tank is relatively small. At this time, the second pressure relief strategy can be used as the target pressure relief strategy to release pressure by opening the rollover valve and the refueling limit valve together, thereby ensuring that the fuel tank can be released smoothly.

[0046] Step S223: Control the oil tank to release pressure based on the first pressure relief strategy or the second pressure relief strategy.

[0047] In an exemplary embodiment of the present application, when controlling the oil tank to release pressure based on the first pressure relief strategy or the second pressure relief strategy, a corresponding waiting time may be set to cope with the situation where the pressure relief is slow, resulting in misdiagnosis of pressure relief failure.

[0048] For example, when the oil tank is controlled to release pressure based on the first pressure relief strategy, a waiting time T1 can be set. After the waiting time T1 is set, the oil tank is controlled to release pressure based on the first pressure relief strategy until the time reaches T1 before continuing with the subsequent steps. When the oil tank is controlled to release pressure based on the second pressure relief strategy, a waiting time T2 can be set to first determine whether the pressure relief is successful after opening the rollover valve and the refueling limit valve. If the pressure relief is successful, continue with the subsequent steps. If the pressure relief fails, the oil tank is controlled to release pressure until the time reaches T2 before determining whether the pressure relief is successful. Finally, continue with the subsequent steps based on whether the pressure relief is successful.

[0049] Step S230: Generate a target refueling signal based on the pressure relief information.

[0050] In an exemplary embodiment of the present application, if it is determined based on the pressure relief information that the time for controlling the oil tank to release pressure based on the first pressure relief strategy reaches T1, the corresponding target refueling signal is generated as a refueling permission signal, otherwise a refueling prohibition signal is generated.

[0051] In an exemplary embodiment of the present application, if the fuel tank is successfully depressurized based on the second pressure relief strategy, the corresponding target refueling signal is a refueling permission signal. Whether the pressure relief is successful can be determined by comparing the pressure in the fuel tank with the corresponding preset pressure in the pressure relief information.

[0052] In addition, if the fuel tank fails to be depressurized based on the second pressure relief strategy, the depressurization time of the fuel tank is obtained. If the depressurization time is greater than the first preset time T2 and the fuel filler cap is not unlocked, emergency unlocking information is generated. The emergency unlocking information includes a refueling prohibition signal, a pressure relief fault signal, and a request for emergency unlocking of the fuel filler cap. Then, feedback information corresponding to the emergency unlocking information is obtained. The feedback information includes a request for emergency unlocking of the fuel filler cap, that is, whether the fuel filler cap needs to be unlocked in an emergency or not. If the fuel filler cap needs to be unlocked in an emergency, the fuel filler cap is still controlled to be unlocked; if not, a refueling stop signal is generated.

[0053] Step S240: If the target refueling signal is determined to be a refueling permission signal, the fuel filler cap is controlled to be unlocked. If the target refueling signal is determined to be a refueling prohibition signal, the fuel filler cap is controlled not to be unlocked.

[0054] In an exemplary embodiment of the present application, in an exemplary embodiment of the present application, Figure 4 A schematic flow chart of S250-S290 of a vehicle fuel filling control method provided in an embodiment of the present application is shown, combined with Figure 4 As shown, after the fuel filler cap is controlled to be unlocked, the vehicle fuel filling control method further includes:

[0055] Step S250: Obtain unlocking information of the fuel filler cap to determine whether the fuel filler cap is unlocked successfully.

[0056] Step S260: If it is determined based on the unlocking information that the fuel filler cap is unlocked unsuccessfully, a fuel filler cap unlocking abnormality signal is generated. If it is determined based on the unlocking information that the fuel filler cap is unlocked successfully, the opening and closing information of the fuel filler cap is acquired in real time.

[0057] In an exemplary embodiment of the present application, after the fuel filler cap unlocking fails and a fuel filler cap unlocking abnormality signal is generated, the user can perform emergency unlocking of the fuel filler cap through the mechanical pull cable of the fuel filler cap lock. After the fuel filler cap is emergency unlocked, the real-time opening and closing information of the fuel filler cap is that the fuel filler cap is open. If the user does not perform emergency unlocking of the fuel filler cap through the mechanical pull cable of the fuel filler cap lock, the real-time opening and closing information of the fuel filler cap is that the fuel filler cap is not open.

[0058] Step S270: If it is determined based on the opening and closing information that the fuel filler cap is opened to the target position, the target refueling signal is maintained as a refueling permission signal; if it is determined based on the opening and closing information that the fuel filler cap is not opened to the target position, a fuel filler cap opening abnormality signal is generated, and then the user is prompted that the fuel filler cap is opened abnormally, and the user is prompted to open the fuel filler cap manually by pressing the open cover, etc., until the fuel filler cap is opened to the target position, and then the target refueling signal is maintained as a refueling permission signal.

[0059] In an exemplary embodiment of the present application, after the fuel filler cap is unlocked, it is also necessary to determine whether the fuel filler cap is opened to the target position according to the opening and closing information of the fuel filler cap, so as to determine whether the fuel filler cap is successfully opened. The fuel filler cap not being opened to the target position includes the situation that the fuel filler cap is only unlocked but not opened, and the fuel filler cap is not opened to the position where fuel can be added after being unlocked. The fuel filler cap being opened to the target position means that after the fuel filler cap is at the target position, the position where fuel can be added smoothly.

[0060] Step S280: If it is determined based on the unlocking information that the fuel filler cap is unlocked successfully and the fuel filler cap is opened to the target position, the vehicle speed information is obtained in real time.

[0061] In an exemplary embodiment of the present application, when the fuel filler cap is unlocked successfully and opened to the target position, a refueling timer may be started to determine whether the user has completed refueling.

[0062] Step S290: If the vehicle speed information or the opening and closing information of the fuel filler cap meets the preset refueling completion condition, a refueling stop signal is generated.

[0063] In an exemplary embodiment of the present application, the vehicle speed information includes the vehicle speed value, which facilitates determining whether the vehicle is in a moving state. The opening and closing information of the fuel filler cap includes the duration of the refueling timer. The preset refueling completion condition includes whether the vehicle speed value is greater than a preset speed value (for example, the preset speed value is 0), or whether the duration of the refueling timer is greater than the duration T3.

[0064] For example, when the fuel filler cap is unlocked successfully and opened to the target position, if the refueling timer is longer than time T3, a refueling stop signal is generated; or, if the vehicle speed is greater than a preset speed, a refueling stop signal is generated.

[0065] It should be understood that when the time length of the refueling timer is greater than the time length T3, it means that refueling has been completed, but the fuel filler cap is not closed. The vehicle speed value is greater than the preset vehicle speed value, which may also mean that refueling may have been completed, but the fuel filler cap is not closed.

[0066] Furthermore, after the fuel filler cap is closed, a signal indicating that refueling is completed can be generated as a prompt. After detecting that the fuel filler cap is not closed, a signal indicating that the fuel filler cap is not closed can be generated as a prompt. If the vehicle speed is greater than a preset speed value, a signal confirming that the gun is drawn can also be generated as a prompt.

[0067] In addition, after the refueling stop signal is generated, the fuel tank isolation valve is closed. If the rollover valve or the refueling limit valve is not closed, the corresponding rollover valve or the refueling limit valve can be automatically closed to stop the pressure relief.

[0068] In summary, when the vehicle is ready to refuel, and after the vehicle receives the refueling request instruction, it will obtain the vehicle's gear information and engine start-stop information, so as to control the fuel tank to release pressure after the vehicle's gear information and engine start-stop information meet the preset pressure relief conditions of the vehicle's fuel tank. Therefore, it can avoid the situation where the vehicle controls the fuel tank to release pressure when the preset pressure relief conditions are not met, which leads to pressure relief failure and ultimately the failure to unlock the fuel filler cap. Among them, when controlling the fuel tank to release pressure, the high-pressure fuel tank isolation valve is first controlled to open to perform pressure relief, and the pressure relief timing is started at the same time, and it is determined whether only the rollover valve is opened, or the refueling restriction valve and the rollover valve are opened at the same time according to the relationship between the remaining fuel value and the remaining fuel threshold. After the pressure relief is successful, a refueling permission signal is generated, otherwise it continues to wait until it fails after the time T2, then a refueling prohibition signal is generated to prompt "refueling pressure relief failure", and further judge whether there is an emergency unlocking request for the fuel filler cap according to the feedback information, if so, the unlocking of the fuel filler cap is controlled, otherwise a refueling stop signal is generated.

[0069] Then, after the refueling permission signal is generated, the control is to unlock the fuel filler cap, and determine whether the fuel filler cap is unlocked successfully based on the unlocking information of the fuel filler cap. If the fuel filler cap is unlocked unsuccessfully, a fuel filler cap unlocking abnormality signal is generated to prompt "the fuel filler cap unlocking abnormality, please unlock it mechanically"; if the fuel filler cap is unlocked successfully, it is determined whether the fuel filler cap is opened to the target position. If so, a refueling request signal is generated and the timing is started. If not, a fuel filler cap opening abnormality signal is generated, and a prompt "the fuel filler cap opening abnormality, please press manually to open" is given, and then it is determined again whether the fuel filler cap is opened to the target position. If so, a refueling request signal is generated and the refueling timing is started.

[0070] Finally, if the refueling timer is longer than the time T3, a refueling stop signal is generated; or, if the vehicle speed is greater than the preset speed, a refueling stop signal is generated. After the refueling stop signal is generated, it is also possible to detect whether the fuel filler cap is closed and whether the gun is drawn, and generate a prompt message accordingly.

[0071] In summary, the fuel filling control method of the present application can open the fuel filler cap when the fuel tank has a large amount of fuel, and diagnose different fuel levels separately to avoid misdiagnosis; it can also detect and diagnose the refueling conditions, the rationality of the fuel sensor signal, the pressure relief state, and the fuel filler cap opening state and feedback them to the user, and can promptly prompt the user of the exit reason through a prompt signal after refueling is completed. In addition, the fuel filling control method of the present application also provides different opening solutions for pressure relief failure and unlocking failure.
