Description

Technical Field

[0001] This application relates to the technical field of vehicles, and particularly to a fueling control method, device, terminal device, and storage medium. Background Art

[0002] When a vehicle enters a gas station for refueling, if the vehicle is not turned off, static electricity or sparks may be generated, increasing the safety risks of the gas station and the vehicle. Therefore, in related technologies, it is possible to detect whether the fuel tank cap of the vehicle is open, and if the fuel tank cap of the vehicle is open, the engine is turned off to improve the safety of vehicle refueling.

[0003] However, the opening of the fuel tank cap of a vehicle does not necessarily mean that the vehicle will refuel. For example, the user may accidentally touch and open the fuel tank cap, or the fuel tank cap may be accidentally opened due to an abnormal control structure of the fuel tank cap. If the engine is turned off at this time, it will cause the vehicle not to refuel but unable to drive normally, thus affecting the safety of the vehicle. Summary of the Invention

[0042] The following will describe in detail the embodiments of the technical solution of the present application with reference to the drawings. The following embodiments are only used to illustrate the technical solution of the present application more clearly and therefore are only examples and cannot be used to limit the protection scope of the present application.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present application; the terms "including" and "having" and any variations thereof in the specification and claims of the present application and the above description of the drawings are intended to cover non-exclusive inclusion.

[0044] In the description of the embodiments of the present application, technical terms such as "first" and "second" are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity, specific order or primary-secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "a plurality of" is more than two, unless otherwise specifically defined.

[0045] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0046] In the description of the embodiments of the present application, the term "a plurality of" refers to more than two (including two). Similarly, "a plurality of groups" refers to more than two groups (including two groups), and "a plurality of paths" refers to more than two paths (including two paths).

[0047] When a vehicle enters a gas station for refueling, if the vehicle is not turned off, static electricity or sparks may be generated, increasing the safety risks of the gas station and the vehicle. Therefore, in the related art, it is possible to detect whether the fuel tank cap of the vehicle is open. If the fuel tank cap of the vehicle is open, the user is prompted to turn off the engine to turn off the vehicle, and when the prompt timing reaches a preset duration, the engine is automatically turned off to improve the safety of vehicle refueling.

[0048] However, the opening of the fuel tank cap of the vehicle does not mean that the vehicle will definitely refuel. For example, the user may open the fuel tank cap by mistake, or the fuel tank cap may be accidentally opened due to an abnormal control structure of the fuel tank cap. If the engine is turned off at this time, it will cause the vehicle not to refuel but unable to drive normally. Even if the fuel tank cap is accidentally opened during the driving of the vehicle, it may also cause safety hazards due to the engine being turned off, thus affecting the safety of the vehicle.

[0049] In view of the above technical problems, an embodiment of the present application provides a refueling control method. When it is detected that the fuel gun of the connected refueling device is inserted into the fuel filler neck of the vehicle, if it is detected that the current vehicle speed meets the refueling conditions, the vehicle is prompted to turn off the engine. And if it is determined that the engine has not been turned off within a preset time period after the vehicle has received the prompt, after controlling the engine to turn off, the connected refueling device is then controlled to switch to an openable state, so that the refueling device can perform a refueling operation. Thus, when it is determined that the vehicle is ready to refuel by detecting the insertion of the fuel gun and the vehicle speed, the user is reminded to turn off the engine, and if the reminder fails, the engine is controlled to turn off. After the engine is turned off, the vehicle is then controlled to refuel, so as to reduce the possibility of the engine being accidentally turned off due to misjudgment of vehicle refueling while reducing the refueling risk of the vehicle, thereby improving the safety of the vehicle.

[0050] The refueling control method, device, terminal device and storage medium disclosed in the embodiments of the present application can be applied to a terminal device for controlling vehicle refueling. Among them, the terminal device can be any one of a mobile terminal, a desktop terminal, a vehicle-mounted terminal or a server, etc. The server can be implemented by an independent server or a server cluster composed of multiple servers, and can also be a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence sampling point devices.

[0051] According to some embodiments of the present application, an embodiment of the present application provides a refueling control method, which can be applied to the aforementioned terminal device for controlling vehicle refueling. As Figure 1 shown, the refueling control method includes:

[0052] S101, detecting whether a first prompt signal indicating that the fuel gun is inserted into the fuel filler neck of the vehicle is received;

[0053] S102, determining that the first prompt signal is received, and obtaining the current vehicle speed of the vehicle;

[0054] S103, determining that the vehicle meets the refueling conditions according to the current vehicle speed, and generating a second prompt signal for prompting the vehicle to turn off the engine;

[0055] S104, determining that the engine of the vehicle has not been turned off within a preset time period after the vehicle has received the second prompt signal, and sending a control signal for controlling the engine of the vehicle to turn off to the vehicle;

[0056] S105, in the case of connecting to the refueling device corresponding to the fuel gun, determining that the engine of the vehicle has been turned off, and controlling the refueling device to switch to an openable state, so that the refueling device can perform a refueling operation.

[0057] In some embodiments, the fuel filler neck of a vehicle may be provided with sensing equipment for detecting whether a fuel gun is inserted into the fuel filler neck. For example, an infrared sensor, a pressure sensor, or a Hall sensor may be arranged near the fuel filler neck of the vehicle to detect whether the fuel gun is inserted into the fuel filler neck. Exemplarily, an infrared transmissive sensor may be provided near the fuel filler neck of the vehicle. Its transmitting end (IR LED) may be installed on one side of the fuel filler neck, such as the top, and its receiving end (phototransistor / IR receiver) may be installed on the opposite side of the fuel filler neck, such as the bottom. When the fuel gun is not inserted into the fuel filler neck, the infrared light directly irradiates from the transmitting end to the receiving end, and the receiving end detects a high-level signal and sends it to the terminal device. At this time, the terminal device can determine that the fuel gun is not inserted into the fuel filler neck. When the fuel gun is inserted into the fuel filler neck, the fuel gun blocks the infrared light, and the signal of the receiving end becomes low level. The signal received by the terminal device is a low-level signal. At this time, the terminal device can determine that it has received a first prompt signal indicating that the fuel gun is inserted into the fuel filler neck of the vehicle.

[0058] In some embodiments, the terminal device may be an in-vehicle terminal, such as the ECU (Electronic Control Unit) of the vehicle. The in-vehicle terminal is communicatively connected to the sensing equipment to determine whether it has received a first prompt signal indicating that the fuel gun is inserted into the fuel filler neck of the vehicle based on the signal sent by the sensing equipment. Alternatively, the terminal device may be a server. The server is communicatively connected to the ECU of the vehicle, and the ECU is communicatively connected to the sensing equipment. The server can receive the signal sent by the sensing equipment through the ECU to determine whether it has received a first prompt signal indicating that the fuel gun is inserted into the fuel filler neck of the vehicle.

[0059] In some embodiments, if a first prompt signal indicating that the fuel gun is inserted into the fuel filler neck of the vehicle is received, it can be determined that the fuel gun has been inserted into the fuel filler neck. At this time, the terminal device can obtain the current vehicle speed of the vehicle and detect whether the current vehicle speed is less than or equal to a preset vehicle speed, such as whether the current vehicle speed is zero. If the current vehicle speed is zero, it means that the vehicle is in a completely stationary state. At this time, it can be determined that the vehicle meets the refueling conditions. Otherwise, it can be determined that the vehicle does not meet the refueling conditions.

[0060] When the vehicle meets the refueling conditions, a second prompt signal for prompting the vehicle to turn off the engine can be generated to prompt the driver to turn off the vehicle engine. For example, the second prompt signal can be displayed on the central control display screen of the vehicle, or the second prompt signal can be sent to the user terminal of the driver to prompt the driver to turn off the vehicle engine.

[0061] Meanwhile, start timing at the moment when the second prompt signal is generated, and detect whether the vehicle shuts down the engine within a preset duration. If it is detected that the vehicle shuts down the engine within the preset duration, such as detecting that the vehicle switches to the LOCK state, ACC state or ON state within the preset duration, it can be determined that the vehicle has shut down the engine within the preset duration, and at this time, the detection of the engine ends; if it is detected that the vehicle does not shut down the engine within the preset duration, such as detecting that the vehicle remains in the START state within the preset duration, it can be determined that the vehicle does not shut down the engine within the preset duration.

[0062] It can be understood that since the ECU does not work when the vehicle is in the LOCK state, if the terminal device is a device other than the in-vehicle terminal, such as a server, it can be determined whether the vehicle shuts down the engine by detecting whether the vehicle switches from the START state to the LOCK state, ACC state or ON state within a preset duration. For example, if the terminal device communicates with the ECU, when the vehicle switches from the START state to the LOCK state, the ECU shuts down, and at this time, the terminal device can detect that the ECU shuts down, thereby determining that the vehicle switches to the LOCK state, and further determining that the engine shuts down; if the vehicle switches to the ACC state or ON state, the ECU can detect this state and send this state to the terminal device, and at this time, the terminal device can determine that the engine shuts down according to the received ACC state or ON state. If the terminal device is an in-vehicle terminal, such as an ECU, it can be determined whether the vehicle shuts down the engine by detecting whether the vehicle switches from the START state to the ACC state or ON state within a preset duration.

[0063] If it is detected that the vehicle does not shut down the engine within the preset duration, a control signal for shutting down the engine is sent to the vehicle to shut down the engine. Exemplarily, if the terminal device is a device other than the in-vehicle terminal, such as a server, a control signal for controlling the engine to shut down can be sent to the vehicle to control the vehicle to switch from the START state to the LOCK state, ACC state or ON state to control the engine to shut down; if the terminal device is an in-vehicle terminal, such as an ECU, a control signal can be sent to control the vehicle to switch from the START state to the ACC state or ON state to control the engine to shut down.

[0064] In some embodiments, before the vehicle refuels, the terminal device can pre-connect to multiple refueling devices, that is, the terminal device can pre-establish communication channels with multiple refueling devices, such as establishing communication channels with multiple refueling devices through DSRC (Dedicated Short Range Communication), C-V2X (Cellular Vehicle-to-Everything), or the Internet of Things, so as to communicate with multiple refueling devices. When the fuel gun is inserted into the fuel inlet of the vehicle, the terminal device can detect whether it has connected to the refueling device corresponding to the fuel gun, such as whether it can communicate with the fuel dispenser equipped with the fuel gun. If the terminal device has connected to the refueling device corresponding to the fuel gun, then when it detects that the vehicle's engine is turned off, it controls the refueling device to switch to the enabled state, so that the refueling device can perform the refueling operation. Here, the enabled state means that the refueling device is awakened and can supply fuel through the fuel gun it is equipped with, such as supplying fuel by operating the fuel gun of the refueling device. If it detects that the vehicle's engine is not turned off, it can control the refueling device to close, that is, control the refueling device to switch to the closed state or the stopped state of stopping fuel supply, to avoid refueling the vehicle when the engine is not turned off.

[0065] When it is detected that the fuel gun of the connected refueling device is inserted into the fuel inlet of the vehicle, if it is detected that the current vehicle speed meets the refueling condition, the vehicle is prompted to turn off the engine. And when it is determined that the vehicle has not turned off the engine within the preset time, after controlling the engine to turn off, then control the connected refueling device to switch to the enabled state, so that the refueling device can perform the refueling operation. Thus, when it is determined that the vehicle is ready to refuel by detecting the insertion of the fuel gun and the vehicle speed, the user is reminded to turn off the engine and, after the reminder fails, control the engine to turn off, and then control the vehicle to refuel after turning off the engine, so as to reduce the possibility of the engine being mis-shut down due to misjudgment of vehicle refueling while reducing the refueling risk of the vehicle, thereby improving the safety of the vehicle.

[0066] To further improve the safety of vehicle refueling, in some embodiments, determining that the first prompt signal is received and obtaining the current vehicle speed of the vehicle includes:

[0067] When it is detected that the fuel tank cap of the vehicle is opened, determine that the first prompt signal is received and obtain the current vehicle speed of the vehicle.

[0068] Considering that if only relying on the fuel gun signal, the vehicle may enter the refueling mode incorrectly when the fuel tank cap is not opened. For example, non-standard fuel guns or foreign objects with inconsistent diameters may accidentally trigger the sensor, resulting in misjudging that the vehicle has entered the refueling mode, which may lead to incorrect control of the vehicle engine. Therefore, in order to further improve the safety of the vehicle, in some embodiments, it is possible to detect whether the fuel tank cap of the vehicle is open and whether the first prompt signal is received. If it is detected that the fuel tank cap of the vehicle is not open and the first prompt signal is determined to be received, it indicates that there is an abnormality in the vehicle. At this time, the refueling control of the vehicle is stopped, and an alarm signal for prompting abnormal refueling of the vehicle is generated to prompt the driver that there is an abnormality in the fuel tank cap or the fuel filler neck. If it is detected that the fuel tank cap of the vehicle is open, and when the first prompt signal is determined to be received when the fuel tank cap of the vehicle is open, it indicates that the vehicle is ready to refuel. At this time, the current vehicle speed of the vehicle can be obtained to determine whether the vehicle can refuel.

[0069] Through the dual detection of the fuel tank cap and the first prompt signal, the situation where the vehicle may enter the refueling mode incorrectly when the fuel tank cap is not opened is intercepted. When it is detected that the fuel tank cap of the vehicle is open and the first prompt signal is received at the same time, the current vehicle speed of the vehicle is obtained to determine whether the vehicle can refuel, thereby improving the safety of the vehicle.

[0070] And in order to further improve the safety of the vehicle, in some embodiments, the method further includes:

[0071] According to the current vehicle speed, it is determined that the vehicle does not meet the refueling conditions, an alarm message for prompting the user to brake is generated, and the vehicle is controlled to brake until the vehicle meets the refueling conditions.

[0072] In some embodiments, if the first prompt signal indicating that the fuel gun is inserted into the fuel filler neck of the vehicle is received, it can be determined that the fuel gun has been inserted into the fuel filler neck. At this time, the terminal device can obtain the current vehicle speed of the vehicle and detect whether the current vehicle speed is less than or equal to the preset vehicle speed, such as whether the current vehicle speed is zero. If the current vehicle speed is greater than zero, it means that the vehicle is in a moving state. At this time, it can be determined that the vehicle does not meet the refueling conditions.

[0073] If it is detected that the vehicle does not meet the refueling conditions, that is, the current vehicle speed is greater than zero, an alarm message for prompting the user to brake can be generated to remind the user to shift the vehicle into the P gear and trigger the handbrake. At the same time, the emergency brake of the vehicle can be triggered to control the vehicle to brake until the vehicle meets the refueling conditions, that is, until the current vehicle speed of the vehicle is zero. Thereby, the possibility of the vehicle slipping due to the handbrake not being pulled or not being shifted into the P gear, resulting in dragging of the fuel gun, can be reduced, and the safety of vehicle refueling can be further improved.

[0074] If the vehicle meets the refueling condition, a second prompt signal for prompting the vehicle to turn off the engine is generated to prompt the driver to turn off the engine. If the driver does not turn off the engine within the preset time period, a control signal for controlling the vehicle's engine to turn off is sent to the vehicle to control the engine to turn off.

[0075] In the case of accessing the refueling device corresponding to the fuel gun, when the vehicle's engine is turned off, the refueling device can be controlled to switch to the operable state. To accurately determine whether the refueling device corresponding to the fuel gun is the refueling device accessed by the terminal device to reduce the possibility of miscontrol, in some embodiments, such as Figure 2 shown, the method further includes:

[0076] S201, determine that the first prompt signal is received, identify the tag information of the fuel gun, and obtain the device information of the refueling device corresponding to the fuel gun from the tag information;

[0077] S202, based on the device information, determine that the refueling device has been accessed, and take over the refueling device to control the working state of the refueling device.

[0078] In some embodiments, such as Figure 3 shown, a card reader B can be provided inside the fuel tank cap A, and the card reader can be communicatively connected to the terminal device. A radio frequency tag can be provided on one side of the fuel gun, and the radio frequency tag can be sensed by the card reader B after the fuel gun is inserted into the fuel filling port of the vehicle. The radio frequency tag stores the tag information of the fuel gun, and the tag information can include the device information of the refueling device corresponding to the fuel gun, and the device information can include the device ID and the gasoline grade, etc.

[0079] When the first prompt signal for prompting the fuel gun to be inserted into the fuel filling port is received, the terminal device can control the card reader B to turn on. At this time, if the fuel gun is provided with a radio frequency tag, the terminal device can obtain the tag information of the fuel gun through the card reader B. After obtaining the tag information, the tag information can be identified to read the device information of the refueling device corresponding to the fuel gun from the tag information.

[0080] For the obtained device information, the device information can be verified by matching it with the device information of each refueling device pre-connected to the terminal device. For example, the obtained device ID is matched with the device IDs of each refueling device pre-connected to the terminal device. If among the device IDs of each refueling device pre-connected to the terminal device, there is a device ID that is the same as the obtained device ID, it can be determined that the refueling device corresponding to the fuel gun inserted into the fuel filler neck has been connected. At this time, it can be determined that the verification of the device information of this refueling device has passed, and this refueling device can be taken over, such as sending a control request to this refueling device so that the terminal device can control the working state of this refueling device. Thus, it is possible to accurately control the refueling device into which the fuel gun is inserted, and at the same time, by verifying the device information, it is ensured that the refueling device to be controlled is a pre-set refueling device with permissions, thereby further improving the safety of vehicle refueling.

[0081] In some embodiments, after taking over the refueling device, the gasoline grade of the refueling device can also be obtained from the device information of the refueling device, and it is detected whether the gasoline grade matches the preset gasoline grade of the vehicle. Among them, the preset gasoline grade can be the gasoline grade of the gasoline required to be added to the vehicle. For example, if the vehicle needs to add gasoline of grade 92, its preset gasoline grade is 92. If the gasoline grade is greater than or equal to the preset gasoline grade of the vehicle, such as the gasoline grade of the refueling device is 95 and the preset gasoline grade of the vehicle is 92 or 95, it can be determined that the gasoline grade matches the preset gasoline grade of the vehicle. At this time, if it is determined that the engine of the vehicle is turned off, the refueling device can be controlled to switch to an openable state; if the gasoline grade is less than the preset gasoline grade of the vehicle, it can be determined that the gasoline grade does not match the preset gasoline grade of the vehicle. At this time, the refueling device is controlled to close, and the driver is prompted to replace the refueling device to avoid damage to the engine caused by the vehicle adding unsuitable gasoline.

[0082] To further improve the safety of vehicle refueling, in some embodiments, the method further includes:

[0083] Determine that the tag information of the fuel gun is not recognized, or determine that the refueling device is not connected according to the device information, and generate a warning message indicating that the refueling device is untrusted.

[0084] In some embodiments, when receiving a first prompt signal indicating that the fuel gun is inserted into the fuel filling port, the terminal device can control the card reader to turn on. If the fuel gun is equipped with a radio frequency tag, the terminal device can identify the tag information of the fuel gun through the card reader. If the tag information of the fuel gun cannot be identified by the card reader at this time, it means that the fuel gun is not equipped with a radio frequency tag, and the fuel filling device equipped with this fuel gun is not the fuel filling device accessed by the terminal device. At this time, it can be determined that the fuel filling device is not trustworthy, and thus a warning message indicating that the fuel filling device is not trustworthy is generated to prompt the user to stop fueling. Or, if the device information verification of the fuel filling device fails, such as the device ID that does not match the device ID of this fuel filling device, it means that the fuel filling device equipped with this fuel gun is not the fuel filling device accessed by the terminal device. At this time, it can be determined that the fuel filling device is not trustworthy, and thus a warning message indicating that the fuel filling device is not trustworthy is generated to prompt the user to stop fueling. Therefore, the reliability of the gasoline added to the vehicle can be indirectly identified through the identification of the fuel filling device, so as to reduce the possibility of the vehicle adding inferior gasoline or non-standard gasoline, and further improve the safety of vehicle fueling.

[0085] In some embodiments, the method further includes:

[0086] After determining that the engine of the vehicle is turned off, it further includes:

[0087] Determine that the engine of the vehicle is restarted, and detect whether there is the first prompt signal at the moment when the engine is restarted;

[0088] Determine that there is the first prompt signal, regenerate a second prompt signal indicating that the vehicle is turned off, and control the gear of the vehicle to be locked in the parking gear.

[0089] In some embodiments, after the engine of the vehicle is turned off, it is possible to detect whether the engine of the vehicle is restarted. If it is detected that the engine of the vehicle is restarted, then detect whether there is a first prompt signal at the moment when the engine is restarted to determine whether the fuel gun is inserted into the fuel filling port of the vehicle at the moment when the engine is restarted. If there is no first prompt signal, it can be determined that the fuel gun has been withdrawn from the fuel filling port and the fuel filling process has ended. At this time, the engine start will not affect the fuel filling, and at this time, the fuel filling control of the vehicle is ended to enable the vehicle to run normally.

[0090] When there is a first prompt signal at the moment when the engine is restarted, it can be determined that the fuel gun has not been withdrawn from the fuel filler, and the refueling process is not over. At this time, starting the engine will affect refueling, and the driver will often control the vehicle to drive after restarting the engine, resulting in dragging of the fuel gun. Therefore, if it is detected that there is a first prompt signal at the moment when the engine is restarted, a second prompt signal for prompting the vehicle to turn off the engine is regenerated to remind the user to turn off the engine, and at the same time, the gear of the vehicle is controlled to be locked in the parking gear to prevent the driver from dragging the fuel gun due to shifting gears to drive the vehicle, thereby further improving the safety of vehicle refueling.

[0091] In some embodiments, after controlling the gear of the vehicle to be locked in the parking gear, the electronic handbrake of the vehicle can also be triggered to prevent the vehicle from slipping, thereby further preventing dragging of the fuel gun.

[0092] Considering the possibility of accidental touch of the sensor provided near the fuel filler, for example, the sensor for detecting whether the fuel gun is inserted into the fuel filler is an infrared opposed sensor provided near the fuel filler. During the refueling process, the infrared opposed sensor may be stained with oil and dirt, resulting in the infrared light at the transmitting end being blocked. At this time, even if the fuel gun has been withdrawn from the fuel filler, the first prompt signal will still be detected, resulting in miscontrol of the vehicle gear.

[0093] Therefore, in some embodiments, determining the existence of the first prompt signal, regenerating a second prompt signal for prompting the vehicle to turn off the engine, and controlling the gear of the vehicle to be locked in the parking gear includes:

[0094] Determine the existence of the first prompt signal and detect the current state of the fuel tank cap;

[0095] Determine that the current state of the fuel tank cap is the open state, regenerate a second prompt signal for prompting the vehicle to turn off the engine, and control the gear of the vehicle to be locked in the parking gear.

[0096] In some embodiments, after the engine of the vehicle is turned off, it can be detected whether the engine of the vehicle is restarted. If a first prompt signal is detected at the moment when the engine of the vehicle is restarted, it means that the fuel gun may not have been withdrawn from the fuel filler. At this time, the current state of the fuel tank cap can be detected, such as obtaining the current state of the fuel tank cap through the ECU.

[0097] If the current state of the fuel tank cap is the closed state, it means that the fuel gun has been withdrawn at this time, and the first prompt signal is not credible. At this time, the refueling control of the vehicle can be stopped to make the vehicle run normally.

[0098] If the current state of the fuel tank cap is open, it can be determined that the fuel gun has not been pulled out and the refueling process has not ended based on the open state of the fuel tank cap and the first prompt signal. At this time, a second prompt signal is regenerated to prompt the vehicle to shut down, so as to remind the user to turn off the engine, and at the same time control the vehicle gear to lock in the parking gear. Therefore, through the dual verification of the current state of the fuel tank cap and the first prompt signal, it is determined whether the fuel gun is pulled out from the refueling port, so as to reduce the possibility of misjudgment of the plug-in and unplug state of the fuel gun, thereby reducing the miscontrol of the vehicle gear.
