TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle control, in particular to a method and system for controlling a fuel filler door motor of a hybrid vehicle and related equipment. BACKGROUND

[0002] At present, the fueling operation of most hybrid vehicles needs to be performed when the vehicle is in the "key ON" or "ready" state. The user usually issues an instruction through a virtual fueling request button on the center display screen, and the instruction is transmitted to the related control unit through the vehicle bus (such as CAN bus), thereby triggering the opening operation of the fuel filler door. Since this method relies on bus communication, and the bus system only works normally when the vehicle is powered on, such a fueling request mechanism cannot be realized when the vehicle is powered off (i.e., the key is off). This results in the user having to start the vehicle or enter the ready state before fueling, which not only increases the operation steps, but also limits the flexibility of the fueling scenario to some extent. SUMMARY

[0022] In order to enable those skilled in the art to better understand the technical solutions of the present application, the exemplary embodiments of the present application are described below with reference to the accompanying drawings, which include various details of the embodiments of the present application to help understanding, and should be considered as merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Also, for the sake of clarity and conciseness, the description below omits the description of well-known functions and structures.

[0024] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0025] The terms used herein are only used to describe specific embodiments, and are not intended to limit the present application. As used herein, the singular forms "a" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the terms "comprise" and / or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof. The terms "connected" or "coupled" and / or like terms are not limited to a direct connection or coupling, but also include an indirect connection or coupling, whether or not it is physical, mechanical, electrical, and / or the like.

[0026] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present application, and will not be interpreted in an overly literal or overly formal sense unless expressly so defined herein.

[0027] The collection, storage, use, processing, transmission, provision and disclosure of the user personal information in the technical solution of the present application comply with relevant laws and regulations and do not violate public order and good customs. The use of user data in the technical solution complies with relevant national laws and regulations (for example, the "Information Security Technology Personal Information Security Specification" and the like). For example, appropriate measures are taken for personal information access control; the display of personal information is limited; the use purpose of personal information does not exceed the direct or reasonably associated range; the use of personal information eliminates explicit identity orientation and avoids precise positioning to a specific individual.

[0028] In the related art, most of the hybrid vehicles are in the key ON or driving ready state, and the fueling request signal is transmitted through the bus by the fueling request button on the central control screen, and no corresponding fueling control judgment is made for the fault diagnosis of the related parts during the entire fueling process. The fueling signal is transmitted through the bus, and for the hybrid vehicle, fueling can only be performed when the vehicle key is ON or ready, and fueling cannot be performed when the vehicle is powered off. By judging whether the pressure in the fuel tank is greater than or equal to the pressure threshold to control the opening of the fuel filler cap, when the fuel tank pressure sensor and other related parts fail, the correct fueling action cannot be determined.

[0029] To solve at least one of the technical problems existing in the related art described above, the present application provides a fuel filler cap motor control method for a hybrid vehicle, wherein the vehicle is provided with a fueling switch, and the fueling switch is connected to a control unit. It can be understood that the above-mentioned fueling switch is a hardware switch.

[0030] Figure 1 A flowchart of a fuel filler cap motor control method for a hybrid vehicle is provided for the embodiments of the present application. The execution subject of the method can be the above-mentioned control unit, as shown in Figure 1 The fuel filler cap motor control method for the hybrid vehicle includes S101-S103.

[0031] In S101, in response to the fueling request signal triggered by the fueling switch, the oil-gas isolation valve is opened, and the response to the engine request signal is stopped.

[0032] It can be understood that the fueling request signal triggered by the above-mentioned fueling switch is a hardware switch trigger, which is different from the trigger through the central control screen in the related embodiments introduced in the foregoing. The hardware switch trigger can be triggered in the powered-off state of the vehicle.

[0033] In S102, the related parts related to fueling are detected.

[0034] In some embodiments, the detection on the fueling related components includes detection on the fuel gas isolation valve and / or the fuel tank pressure sensor.

[0035] In some embodiments, the detection on the fuel gas isolation valve includes detection on whether the fuel gas isolation valve has a stuck failure and whether it can normally release pressure.

[0036] In S103, if all the fueling related components have no failure and it is detected that the fuel tank pressure has been released to the safe range, the fuel filler cap motor is controlled to perform an unlocking action.

[0037] The present application actively controls the fuel gas isolation valve to open in response to the signal triggered by the fueling switch, and suspends the response to the engine request signal during the process, effectively avoiding the safety hazard caused by the engine starting due to misoperation during fueling, and improving the safety and reliability of fueling operation. The failure detection link of the fueling related components is introduced, the real-time diagnosis of the working state of the key components is realized, and the fuel filler cap motor is controlled to perform an unlocking action only after confirming that all the related components have no failure and the fuel tank pressure has been reduced to the safe range. Not only does it comply with the safety specifications for fueling, but also improves the success rate and experience of user operation.

[0038] In some embodiments, as shown in Figure 2 If there is a failed component among the fueling related components and the forced unlocking signal triggered by the fueling switch is not received, the fuel filler cap motor is not controlled to perform an unlocking action.

[0039] If there is a failed component among the fueling related components and the forced unlocking signal triggered by the fueling switch is received, the fuel filler cap motor is controlled to perform an unlocking action.

[0040] The fueling request signal and the forced unlocking signal are triggered by different actions of touching the fueling switch. In some embodiments, the different actions of touching the fueling switch can include short pressing, long pressing, pressing twice in succession, pressing three times in succession, etc. For example, short pressing triggers the fueling request signal, and long pressing triggers the forced unlocking signal.

[0041] In some embodiments, if all the fueling related components have no failure and it is detected that the fuel tank pressure has not been released to the safe range, but the forced unlocking signal triggered by the fueling switch is received, the fuel filler cap motor is controlled to perform an unlocking action.

[0042] In some embodiments, the method further includes, after recognizing that the gear is in the driving gear, controlling the fuel filler cap motor to perform a locking action, controlling the fuel gas isolation valve to close, and continuing to respond to the engine request signal.

[0043] The application realizes that the controller is woken up and the refueling request is recognized by pressing the refueling switch in the vehicle power-off state (key OFF) by directly connecting the refueling switch to the hardware wake-up pin of the controller in a hard-wired manner, gets rid of the restriction that the traditional scheme relies on vehicle bus communication and must be in the vehicle power-on (ON / Ready) state to refuel, and greatly improves the convenience and use flexibility of the user to directly refuel after the vehicle is parked and turned off; after recognizing the refueling request, the controller not only controls the oil-gas isolation valve to depressurize, but also detects key components such as the oil-gas isolation valve jam and the oil tank pressure sensor in real time, and judges whether the oil tank pressure has decreased to the safe range. Only when all conditions are met, the unlocking action is performed to ensure that the refueling operation is carried out in a safe and controllable manner, effectively preventing the risk of abnormal opening caused by component failure; when detecting that the related components have faults, the refueling is not completely prohibited, but the user is allowed to trigger a forced unlocking instruction by pressing the refueling switch for 3-5 seconds, fully considering the reliability requirement in actual use, ensuring that the user can complete refueling even when some non-critical components fail, and significantly improving the robustness and user experience of the system.

[0044] The application will be described in detail below Figure 3 and Figure 4 The refueling port cover motor control method of the hybrid vehicle of the application will be described in detail as follows: Figure 3 and Figure 4 The specific control steps are described as follows:

[0045] When the vehicle is powered off (key OFF state), the refueling switch button (hard-wire self-resetting switch) is pressed, the control unit detects the refueling request signal at the same time, the control unit is woken up, the refueling intention is recognized, the oil-gas isolation valve is controlled to open, and the oil tank pressure is depressurized. In addition, after recognizing the refueling request, the control unit will no longer respond to the engine request signal, and enter a delay sleep state to ensure that the entire refueling process can be completed smoothly.

[0046] After recognizing the refueling intention, the control unit will control the oil-gas isolation valve to open at the same time, and will detect the related components, will detect whether the oil-gas isolation valve has a jam fault and can normally depressurize, will detect whether the oil tank pressure sensor has a fault and whether the detected oil tank pressure is accurate, and will also detect whether the oil tank pressure has been depressurized to the safe range if the above two faults do not exist.

[0047] If the above three abnormal conditions do not exist, the control unit directly controls the refueling port cover motor to perform the unlocking action, and controls the refueling port cover to open and normally refuel.

[0048] If any of the above three conditions is not met, the oil filler cap motor can be forced to unlock by pressing the oil switch (3-5s) again to control the oil filler cap motor to perform a forced unlocking action, and the oil filler cap is opened to ensure that the oiling process is completed smoothly.

[0049] After the oiling process is completed, the control unit detects that the vehicle owner has a driving intention, and when the gear is switched to the driving gear (D / R gear), the oil filler cap motor is controlled to perform a locking action, and at the same time, the oil and gas isolation valve is closed, and the engine start request is continuously responded.

[0050] The oil switch of the present application is connected through hardware, and the hardware wake-up interface is the same hardware pin. Therefore, the hybrid vehicle owner can not only refuel when the vehicle is powered on or in the driving permission state, but also can refuel by the hardware wake-up control unit to recognize the refueling request in the vehicle power-off state. After recognizing the refueling request, the related parts involved in the refueling process are diagnosed and controlled. Even if a related fault is detected, the oil filler cap motor can be forced to unlock by pressing the oil button according to the owner's own intention, and the oil filler cap is opened for refueling.

[0051] Based on the same inventive concept, the embodiment of the present application also provides an oil filler cap motor control system of a hybrid vehicle, as shown in Figure 5 The oil filler cap motor control system of the hybrid vehicle includes an oil switch 501 and a control unit 502.

[0052] The oil switch 501 is connected to the control unit, and the oil switch is used to send a refueling request signal or a forced unlocking signal to the control unit in response to different touch actions.

[0053] The control unit 502 is used to execute the oil filler cap motor control method of any hybrid vehicle in the above embodiment.

[0054] The present application actively controls the oil and gas isolation valve to be opened in response to the signal triggered by the oil switch, and suspends the response to the engine request signal during this process, effectively avoiding the safety hazards caused by the engine starting due to misoperation during the refueling process, and improving the safety and reliability of the refueling operation. The fault detection link of the refueling related parts is introduced, and the real-time diagnosis of the working state of the key parts is realized. After confirming that all related parts are fault-free and the tank pressure has been reduced to the safe range, the oil filler cap motor is controlled to perform an unlocking action. Not only does it meet the safety specifications of fueling, but also improves the success rate and experience of user operation.

[0055] As shown in Figure 6As shown, the refueling switch is connected to a high level at one end and to the hardware interface of the control unit at the other end; when the refueling switch is pressed, the control unit hardware interface detects a high level and is awakened, and after awakening, the above-mentioned refueling cap motor control method of any one of the hybrid vehicles is executed.

[0056] As an example, one end of the refueling switch is connected to a 12V high level, and the other end is connected to the hardware interface of the control unit, and when the refueling switch is pressed, the interface detects a high level; the hardware interface simultaneously performs hardware wake-up detection and control, that is, when the interface pin detects a high level, the control unit is awakened.

[0057] When the vehicle is powered off (key OFF state), the refueling switch button (hard-wired self-resetting switch) is pressed, the control unit detects the refueling request signal, the control unit is awakened, the refueling intention is recognized, the request oil and gas isolation valve is controlled to open, and the tank pressure is relieved. In addition, after recognizing the refueling request, the control unit will not respond to the engine request signal, and enters a delay sleep state, so as to ensure that the entire refueling process can be successfully completed.

[0058] Most hybrid vehicles are in the key ON or driving ready state, and the refueling request button on the central control screen is used to transmit the refueling request signal through the bus, and no corresponding control judgment is made for the fault of the related parts during the entire refueling process. The idea of the present application is that the refueling request is connected to the control unit by a hard-wired manner, and the hardware wake-up interface is the same hardware interface. In the powered-off state of the vehicle, the owner can also successfully awaken the control unit by pressing the refueling switch, recognize the refueling request, and when the related parts involved in the refueling control process fail, the refueling cap motor can be forcibly unlocked by pressing the refueling switch again, the refueling cap is opened, and refueling is performed. For users, the refueling scene is more abundant and unrestricted, and even if some parts fail (without affecting the safety of the vehicle), the refueling process can still be performed, providing a very good user experience.
