[0012] In a possible implementation, the method further includes: when the liquid level drop acceleration value is greater than the preset reference value, obtaining a real-time pressure value at the current time and a historical pressure value at the previous time in the fuel tank; when the difference between the real-time pressure value and the historical pressure value is greater than a preset difference value, determining that fuel theft occurs in the fuel tank, and generating an alarm signal.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] This invention provides a method, system, vehicle, and storage medium for preventing theft and leakage of fuel in a fuel tank, which will be described below.

[0025] Figure 1 A schematic flowchart of an embodiment of the fuel anti-theft and anti-leakage method for fuel in a fuel tank provided by the present invention is shown below. Figure 1 As shown, the methods for preventing theft and leakage of fuel in the fuel tank include: S101, responding to the anti-theft and anti-leakage opening command, obtains the real-time acceleration value of the liquid level drop in the oil tank through the oil level acceleration sensor.

[0026] The anti-theft and anti-leakage activation command can be generated in response to the driver clicking a designated activation button. Specifically, an activation button can be installed in the driver's compartment or anywhere in the vehicle. When anti-theft and anti-leakage monitoring of the vehicle is required, clicking the activation button will generate the anti-theft and anti-leakage activation command.

[0027] It should be understood that the oil quantity acceleration sensor is arranged in the oil tank to monitor the liquid level drop acceleration value in the oil tank in real time.

[0028] S102, judging whether the liquid level drop acceleration value is greater than a preset reference value.

[0029] The preset reference value refers to a critical liquid level drop acceleration value when the vehicle occurs fuel theft / leakage and does not occur fuel theft / leakage. When the liquid level drop acceleration value is greater than the preset reference value, it is determined that the oil tank occurs fuel theft or leakage, otherwise, the vehicle does not occur fuel theft or leakage.

[0030] S103, when the liquid level drop acceleration value is greater than the preset reference value, it is determined that the oil tank occurs fuel theft or leakage, and an alarm signal is generated.

[0031] It should be understood that the fuel theft and leakage prevention method in the oil tank in the embodiments of the present application can be implemented in any device based on the fuel theft and leakage prevention method in the oil tank, such as a vehicle. Specifically, the fuel theft and leakage prevention method in the oil tank is stored in the above-mentioned device in the form of a prepared program, when the device starts, the program is called, and the fuel theft and leakage prevention method in the oil tank is implemented.

[0032] Compared with the prior art, the fuel theft and leakage prevention method in the oil tank provided by the embodiments of the present application can determine whether the oil tank occurs fuel theft or leakage based on the comparison result of the liquid level drop acceleration value in the oil tank obtained by the oil quantity acceleration sensor in real time and the preset reference value. Compared with the prior art which can only identify one fuel theft mode of the fuel filling port, the liquid level drop acceleration is suitable for any fuel theft mode. It utilizes the characteristic that the liquid level drop acceleration value will significantly increase when fuel theft occurs, thereby improving the applicability of fuel theft prevention. At the same time, when the oil tank occurs abnormal leakage, the characteristic of the liquid level drop acceleration value increasing will also occur, so the embodiments of the present application can also monitor abnormal leakage.

[0033] Further, the embodiments of the present application use the liquid level drop acceleration value instead of the liquid level drop value, which eliminates the problem that the liquid level drop value cannot represent the trend and only reflects the current speed and response lag. In other words, using the liquid level drop acceleration value can improve the response sensitivity of the theft and leakage prevention, improve the timeliness of the alarm signal generation, and improve the alarm accuracy.

[0034] Further, the theft and leakage prevention start instruction of the embodiments of the present application can be generated when the vehicle is stationary or running, that is, the theft and leakage prevention of the stationary vehicle and the running vehicle can be realized, which further improves the scene adaptability of the fuel theft and leakage prevention method in the oil tank, and further ensures the fuel safety of the vehicle.

[0035] In order to avoid misjudgment of leakage and theft due to different vehicle states, in some embodiments of the present application, such asFigure 2 As shown, before step S102, the fuel theft and leakage prevention method in the oil tank comprises: S201, acquiring real-time running state parameters of the vehicle, and determining the vehicle state based on the real-time running state parameters.

[0036] The real-time running state parameters include but are not limited to: vehicle speed signal, longitudinal acceleration, lateral acceleration and vehicle attitude angle change rate.

[0037] S202, determining a preset reference value based on the vehicle state.

[0038] The embodiment of the application can improve the accuracy of the preset reference value setting by determining the preset reference value based on the vehicle state, avoid the misjudgment of oil leakage and theft due to different vehicle states when a single preset reference value is used, and further improve the accuracy of oil leakage and theft monitoring.

[0039] In the specific embodiments of the application, determining the preset reference value based on the vehicle state comprises: When the vehicle state is a static state, the preset reference value is set as a first reference value; When the vehicle state is a stable driving state, the preset reference value is set as a second reference value; When the vehicle state is a dynamic driving condition, the preset reference value is set as a third reference value; The first reference value is less than the second reference value, and the second reference value is less than the third reference value.

[0040] The static state refers to a state in which the vehicle speed signal is zero. The stable driving condition refers to a state in which the vehicle speed signal is not zero, and the absolute values of the longitudinal acceleration signal and the lateral acceleration signal are both lower than a preset value, such as uniform speed or low speed driving state. The dynamic driving condition refers to a state in which the vehicle speed signal is not zero, and the absolute value of the longitudinal acceleration signal or the lateral acceleration signal is higher than a preset value, such as rapid acceleration, rapid deceleration, turning or driving on a bumpy road.

[0041] The embodiment of the present application sets different reference values for different vehicle states, considers the strong correlation between the fuel level in the tank and the vehicle state, when the vehicle is in a static state, due to the stable liquid level, any slight liquid level drop (such as slow fuel theft, slight leakage) will generate a relatively obvious acceleration signal. Therefore, the first reference value with the smallest value is set. When the vehicle is in a dynamic driving condition, the fuel surge after sudden acceleration, the fuel surge before sudden braking, the fuel shift during turning, and the fuel shaking on bumpy road will generate huge and short acceleration peaks. In order to avoid false alarm due to such conditions, the third reference value with the largest value is set, which can improve the reliability of the alarm. In other words, the embodiment of the present application can improve the adaptability of the preset reference value to the vehicle state by setting the preset reference value in stages, so as to further ensure the monitoring accuracy and reliability of fuel theft and leakage.

[0042] Since the first reference value, the second reference value and the third reference value are all set according to experience, they are still fixed values in a fixed vehicle state, which ignores individual differences and cannot cope with vehicle changes. For example, two vehicles of the same model have slight differences in fuel consumption characteristics due to engine internal resistance, pump efficiency, sensor errors, etc. Using a fixed value to measure all vehicles will inevitably lead to false positives and false negatives. At the same time, as the vehicle ages, the engine efficiency decreases, and the fuel consumption increases slightly. A fixed reference value cannot capture this slow trend change, which may lead to frequent false positives of the system when the vehicle ages.

[0043] To solve the above technical problems, in some embodiments of the present application, as shown in Figure 3 The step S202 comprises: S301, obtaining historical fuel consumption data of the vehicle under different operating state parameters; S302, establishing a normal fuel consumption model of the vehicle based on the historical fuel consumption data.

[0044] The normal fuel consumption model can be a numerical model established based on a fuel consumption theoretical formula, or a deep learning model constructed based on deep learning theory.

[0045] S303, adaptively determining the preset reference value based on the normal fuel consumption model.

[0046] The normal fuel consumption model established by the historical fuel consumption data of the embodiment of the present application can determine the standard value of each vehicle in the whole life cycle, and therefore the adaptive determination of the preset reference value based on the normal fuel consumption model can realize the adaptability of the preset reference value to the vehicle, which can greatly improve the accuracy of the preset reference value setting, thereby avoiding false positives and false negatives and improving the monitoring accuracy of fuel theft and leakage.

[0047] To improve the intelligent degree of the alarm, in some embodiments of the present application, the preset reference value includes a slight abnormality reference value, a moderate abnormality reference value and a serious abnormality reference value from small to large; then step S103 is specifically: When the liquid level drop acceleration value is greater than the slight abnormality reference value and less than the moderate abnormality reference value, it is determined as a slight abnormality, and a first-level alarm signal is generated, the first-level alarm signal instructs to send prompt information to a remote terminal.

[0048] Wherein, the remote terminal is a driver's mobile phone or the like, used to remind the driver away from the vehicle that the fuel tank has a slight abnormality. The prompt information is displayed in the form of APP notification or SMS.

[0049] When the liquid level drop acceleration value is greater than or equal to the moderate abnormality reference value and less than the serious abnormality reference value, a second-level alarm signal is generated, the second-level alarm signal instructs to start the sound and light alarm.

[0050] Wherein, the sound and light alarm can be a buzzer and an indicator light, used to warn oil thieves or moderate oil leakage.

[0051] When the liquid level drop acceleration value is greater than or equal to the serious abnormality reference value, a third-level alarm signal is generated, the third-level alarm signal instructs to start the sound and light alarm, and send emergency alarm information to a remote monitoring platform.

[0052] Wherein, the remote monitoring platform can be a fleet management platform.

[0053] It should be noted that: the emergency alarm information includes the geographical position of the vehicle, so that the remote monitoring platform can quickly generate a management scheme based on the geographical position.

[0054] The embodiment of the present application can avoid triggering the sound and light alarm every time a slight abnormality occurs, which causes the driver to be unable to tolerate, and even not to start the anti-theft and anti-leakage function. At the same time, different alarm measures are provided for different degrees of abnormality, which improves the adaptability and intelligent degree of the alarm measures.

[0055] It should be understood that: the slight abnormality reference value, the moderate abnormality reference value and the serious abnormality reference value can be set or adjusted according to the actual application scene, in the specific embodiments of the present application, the slight abnormality reference value is 10mm / s 2 , the moderate abnormality reference value is 30mm / s 2 , and the serious abnormality reference value is 50mm / s 2 .

[0056] To avoid continuous generation of alarm signals, in some embodiments of the present application, the anti-theft and anti-leakage method of the fuel tank also includes: When the liquid level drop acceleration value is detected as zero, a reset instruction is generated, and the reset instruction is used to instruct the actuator to reset the alarm signal.

[0057] Specifically, when the execution structure is a buzzer and an indicator light, the buzzer and the indicator light can be reset to return to a non-alarming state.

[0058] To avoid the inaccuracy caused by a single liquid level drop acceleration value, such as failure of the oil quantity acceleration sensor, in some embodiments of the present application, as shown in the method for preventing fuel theft and leakage in an oil tank, the method further comprises: Figure 4 S401, when the liquid level drop acceleration value is greater than a preset reference value, the real-time pressure value at the current time and the historical pressure value at the previous time in the oil tank are obtained. S402, when the difference between the real-time pressure value and the historical pressure value is greater than a preset difference value, it is determined that fuel theft occurs in the oil tank, and an alarm signal is generated.

[0059] The embodiments of the present application utilize the following characteristics of the oil tank: when the oil tank does not occur oil theft and oil leakage, and the fuel is normally consumed, the engine runs, and the oil is pumped from the bottom of the oil tank by the fuel pump. In order to balance the pressure in the oil tank, the oil tank ventilation system will be opened at the same time, allowing external air to enter the oil tank to fill the space left after the fuel is reduced. Therefore, during the entire normal consumption process, the internal pressure of the oil tank maintains a relative balance with the atmospheric pressure, and will not suddenly drop. When oil theft or abnormal oil leakage occurs, the rate of fuel reduction is much higher than the engine consumption, and the speed of external air replenishment is far behind the speed of fuel being quickly pumped away. Therefore, a short-term negative pressure zone is formed in the oil tank, causing the pressure sensor reading to drop sharply.

[0060] Based on the above characteristics, the pressure change value in the oil tank is used as an auxiliary judgment means for oil theft and leakage, which can further improve the judgment accuracy of oil theft and leakage, and thus improve the accuracy of the alarm.

[0061] ​In summary, the oil tank fuel theft and leakage prevention method provided by the embodiment of the present application, 1, takes the generation of the theft and leakage prevention opening instruction as a prerequisite, and avoids the risk of fuel theft during the period when the driver rests in the vehicle or leaves the vehicle in the stationary state of the vehicle by avoiding the conventional methods such as judging whether the vehicle speed is zero or whether there is an ignition key signal input; and secondly, the risk of fuel tank leakage in the running state of the vehicle is avoided, and the safety of the normal passage of the vehicle is ensured. 2, the fuel theft and leakage behavior is judged based on the fuel level change acceleration value, and once the fuel level drop acceleration value exceeds the preset reference value, it is determined that there is a fuel theft and leakage behavior. Most of the current market anti-theft oil solutions mainly consider structural protection, such as adding an oil tank anti-theft lock, installing an external oil tank protection, etc. The anti-theft oil solutions have the problem of insufficient protection for the oil tank body theft. In addition, the real-time video monitoring measure not only greatly increases the cost of fuel theft prevention, but also requires the driver or the co-driver to be online at all times, which increases the working intensity of the driver or the co-driver, and the practicality is slightly insufficient. The judgment logic of the present application is simple and intuitive, and there is no misjudgment, omission and error. 3, the present application uses a lamp buzzer as an alarm, which can timely and accurately alarm the oil theft behavior; at the same time, prompt information is sent to the remote terminal, and the driver can master the vehicle fuel condition at the first time, and the double warning of the two can help the driver quickly locate the vehicle position and stop the fuel theft and leakage behavior, effectively reducing the property loss caused by the delay of the alarm.

[0062] In another aspect, the embodiment of the present application also provides an oil tank fuel theft and leakage prevention system, as shown in the figure, Figure 5 The oil tank fuel theft and leakage prevention system 500 comprises: A button switch 501 is used to receive a user instruction to generate a theft and leakage prevention opening instruction; A fuel quantity acceleration sensor 502 is arranged in the fuel tank and is used to monitor the fuel level drop acceleration value in the fuel tank in real time; A processing unit 503 is used to judge whether the fuel level drop acceleration value is greater than a preset reference value, and generate an alarm instruction when the fuel level drop acceleration value is greater than the preset reference value; An alarm 504 is used to execute an alarm action in response to the alarm instruction.

[0068] The components 601-604 of the vehicle 600 communicate with each other through a system bus.

[0069] In some embodiments of the present application, when the processor 602 executes the anti-theft and anti-leakage program of the fuel in the oil tank in the memory 601, the following steps can be implemented: In response to the anti-theft and anti-leakage start instruction, the liquid level drop acceleration value in the oil tank based on the real-time acquisition of the oil quantity acceleration sensor is received; It is judged whether the liquid level drop acceleration value is greater than a preset reference value; When the liquid level drop acceleration value is greater than the preset reference value, it is determined that the oil tank has fuel theft or leakage, and an alarm signal is generated.

[0070] It should be understood that: in addition to the above functions, the processor 602 can also implement other functions when executing the anti-theft and anti-leakage program of the fuel in the oil tank in the memory 601, and specific descriptions can be referred to the description of the corresponding method embodiments.

[0071] Among them, the vehicle in the embodiment of the present application refers to a commercial vehicle.
