Description

Technical Field

[0001] This application relates to the field of automotive electronics technology, specifically to a method, device, equipment, and storage medium for detecting the oil level and voltage of a vehicle. Background Technology

[0002] In gasoline-powered vehicles, fuel level is detected by a fuel sensor. The fuel sensor can be considered as a sliding rheostat; as the fuel level rises or falls, its resistance changes accordingly. In other words, the change in the resistance of the fuel sensor reflects the rise or fall of the fuel level. The fuel sensor is generally powered by the ignition system. Theoretically, the supply voltage is constant, but in reality, voltage fluctuations occur during ignition, causing the actual measured voltage of the fuel sensor to not correspond to the theoretical supply voltage.

[0003] In existing technologies, to improve the accuracy of the voltage sampled by the fuel sensor, abnormal values ​​are generally filtered out by introducing circuits or devices with judgment and indication functions. For example, a reference voltage is connected to the detection circuit, the test voltage is compared with the reference voltage by a comparator, and semiconductor devices such as transistors are used to filter out test voltages that do not meet the judgment rules. Existing technologies have at least the following drawbacks: they cannot correct abnormal data, and when the supply voltage fluctuates for a long time, a large amount of detection data will be filtered out, resulting in the fuel level signal not being able to be detected normally, and the vehicle's fuel level cannot be judged in a timely and accurate manner. Summary of the Invention

[0004] In view of the shortcomings of the prior art, which is unable to correct abnormal data and will filter out a large amount of detection data when the power supply voltage fluctuates for a long time, resulting in the inability to detect the oil level signal normally and make timely and accurate judgments on the oil level of the vehicle, the present invention provides a method, device, equipment and storage medium for detecting the oil level voltage of a vehicle to solve the above-mentioned technical problems.

[0005] In a first aspect, the present invention provides a method for detecting the oil level voltage of a vehicle, comprising:

[0006] The first supply voltage is obtained by performing a first sampling operation on the supply voltage of the vehicle power supply system;

[0007] The voltage difference is calculated based on the first supply voltage and the preset standard voltage value, and the voltage difference is compared with the preset voltage difference threshold.

[0008] If the voltage difference is greater than the voltage difference threshold, then a second sampling operation is performed on the power supply voltage and the fuel sensor simultaneously to obtain the second power supply voltage and the first fuel level voltage.

[0009] The sampling ratio coefficient is calculated based on the second supply voltage and the standard voltage value, and the first oil level voltage is corrected using the sampling ratio coefficient to obtain the actual oil level voltage.

[0010] Secondly, the present invention provides a vehicle oil level voltage detection device, comprising:

[0011] The first sampling module is used to perform a first sampling operation on the power supply voltage of the vehicle power supply system to obtain the first power supply voltage.

[0012] The comparison module is used to calculate the voltage difference based on the first supply voltage and a preset standard voltage value, and compare the voltage difference with a preset voltage difference threshold.

[0013] The second sampling module is used to simultaneously perform a second sampling operation on the power supply voltage and the fuel sensor when the voltage difference is greater than the voltage difference threshold, so as to obtain the second power supply voltage and the first fuel level voltage.

[0014] The voltage correction module is used to calculate a sampling ratio coefficient based on the second supply voltage and the standard voltage value, and to correct the first oil level voltage using the sampling ratio coefficient to obtain the actual oil level voltage.

[0015] Thirdly, the present invention provides an electronic device, comprising:

[0016] One or more processors;

[0017] A storage device for storing one or more programs, which, when executed by one or more processors, cause the electronic device to implement a vehicle oil level voltage detection method as described above.

[0018] Fourthly, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a computer processor, causes the computer to perform a vehicle oil level voltage detection method as described above.

[0019] The vehicle fuel level voltage detection method, device, equipment, and storage medium described above first perform a first sampling operation on the power supply voltage of the vehicle's power supply system to obtain a first power supply voltage. The voltage difference is calculated based on the first power supply voltage and a preset standard voltage value. This voltage difference is compared with a preset differential voltage threshold. If the voltage difference is greater than the threshold, a second sampling operation is performed simultaneously on the power supply voltage and the fuel sensor to obtain a second power supply voltage and a first fuel level voltage. A sampling ratio coefficient is calculated based on the second power supply voltage and the standard voltage value, and the first fuel level voltage is corrected using this coefficient to obtain the actual fuel level voltage. This invention solves the problem in the prior art where abnormal data cannot be corrected, and where long-term fluctuations in the power supply voltage filter out a large amount of detection data, leading to abnormal fuel level signal detection and an inability to accurately and timely determine the vehicle's fuel level. This invention can accurately determine the fuel level voltage and correct large errors in real time, effectively avoiding the risk of fuel level monitoring interruptions due to long-term fluctuations in the power supply voltage. It enables continuous acquisition of the fuel level voltage, effectively improving the timeliness and accuracy of fuel level judgment. It features ingenious design, strong vehicle adaptability, and low modification difficulty.

[0026] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0027] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be changed according to actual needs, and the layout of the components may also be more complex.

[0028] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0029] First, it should be noted that the embodiments provided in this application can be applied to the application scenario of vehicle fuel level detection. The fuel level signal is generally detected by a fuel sensor, which can be equivalent to a sliding rheostat. When the fuel level increases or decreases, the resistance value of the fuel sensor changes accordingly, and the current on the fuel sensor will also change synchronously. The instrument system detects the fuel level signal, such as the voltage value, through its internal sampling circuit, and calculates the resistance change based on the fuel level signal. Thus, the fuel level can be monitored based on the changes in the fuel sensor, and the fuel level signal can be displayed on the vehicle's infotainment system or instrument panel in a preset information display format.

[0030] In one embodiment, please refer to Figure 1 This application exemplarily illustrates a method for detecting the oil level voltage of a vehicle, specifically including the following steps:

[0031] Step S110: Perform a first sampling operation on the power supply voltage of the vehicle power supply system to obtain the first power supply voltage;

[0032] Step S120: Calculate the voltage difference based on the first supply voltage and the preset standard voltage value, and compare the voltage difference with the preset voltage difference threshold.

[0033] Step S130: If the voltage difference is greater than the voltage difference threshold, then perform a second sampling operation on the power supply voltage and the fuel sensor simultaneously to obtain the second power supply voltage and the first fuel level voltage.

[0034] Step S140: Calculate the sampling ratio coefficient based on the second power supply voltage and the standard voltage value, and use the sampling ratio coefficient to correct the first oil level voltage to obtain the actual oil level voltage;

[0035] For steps S110-S120, the supply voltage of the vehicle power supply system needs to be sampled, and the voltage difference between it and the preset standard voltage value needs to be calculated. In order to determine the subsequent processing method based on the relationship between the voltage difference and the preset differential voltage threshold, the vehicle power supply system refers to the system that supplies power to the fuel sensor, generally referring to the IGN (Ignition Switch) power supply in the vehicle. When the vehicle power supply system provides voltage to the fuel sensor, the operating voltage of the fuel sensor may fluctuate due to fluctuations in its own output voltage. Therefore, the standard voltage value here should be understood as the voltage provided to the fuel sensor by the vehicle power supply system when there are no voltage fluctuations. The differential voltage threshold should be understood as the maximum acceptable value of fluctuation when the supply voltage fluctuates. If the differential voltage threshold is exceeded, it means that the fluctuation of the supply voltage will have a non-negligible impact on the actual detected fuel level voltage.

[0036] For steps S130-S140, if the voltage difference is greater than the voltage difference threshold, it means that the current supply voltage is fluctuating significantly. The fuel level voltage detected directly by the fuel sensor is likely to be inaccurate. The collected fuel level voltage cannot truly reflect the voltage that the current fuel level should correspond to. At this time, for the fuel level voltage collected from the fuel sensor at a certain moment, it is necessary to correct the fuel level voltage by using the fluctuation of the supply voltage at the same moment.

[0037] It is important to understand that since the voltage collected from the fuel sensor is obtained by dividing the supply voltage based on its resistance, the fuel level voltage and the supply voltage change linearly under a specific resistance. As long as the change ratio of the supply voltage fluctuation relative to the standard voltage value can be obtained, the collected fuel level voltage can be corrected accordingly to calculate the actual fuel level voltage. Therefore, a second sampling operation is performed on the supply voltage and the fuel sensor to obtain the second supply voltage and the first fuel level voltage. The sampling ratio coefficient is calculated based on the second supply voltage and the standard voltage value, and the first fuel level voltage is corrected using the sampling ratio coefficient to obtain the actual fuel level voltage.

[0038] In this embodiment, the sampling operation can be performed, for example, by a voltage acquisition device or by analog signals and / or digital signals and analog-to-digital conversion. For example, in some embodiments of this embodiment, specific implementation methods of sampling are illustrated. For instance, in the step of performing a first sampling operation on the supply voltage of the vehicle power supply system to obtain a first supply voltage, the following steps are specifically included:

[0039] The vehicle power supply system is sampled using a first analog-to-digital converter to obtain a first analog-to-digital conversion value;

[0040] The first supply voltage is calculated based on the first preset accuracy of the first analog-to-digital converter and the first analog-to-digital conversion value;

[0041] For example, in the step of simultaneously performing a second sampling operation on the power supply voltage and the fuel sensor, the second sampling operation includes the following steps:

[0042] The vehicle power supply system is sampled using the first analog-to-digital converter to obtain the second analog-to-digital conversion value. At the same time, the fuel sensor is sampled using the second analog-to-digital converter to obtain the third analog-to-digital conversion value.

[0043] The second power supply voltage is calculated based on the first preset accuracy and the second analog-to-digital conversion value. The first oil level voltage is calculated based on the second preset accuracy and the third analog-to-digital conversion value of the second analog-to-digital converter.

[0044] Regarding the specific implementation of the second sampling operation described in the above steps, it should be understood that the second sampling operation for the power supply voltage and the fuel sensor is performed simultaneously. That is, the obtained second analog-to-digital conversion value and the third analog-to-digital conversion value are time-corresponding. The purpose is to ensure that the calculated second power supply voltage and the first fuel level voltage are also time-corresponding, so that the voltage difference between the second power supply voltage and the standard voltage value, and the impact on the first fuel level voltage, can be correspondingly corrected in the subsequent correction involving the second power supply voltage.

[0045] For example, the first and second sampling operations provided in this embodiment can be performed via analog-to-digital (AD) conversion. First, an AD value is obtained through an Analog-to-Digital Converter (ADC), and then the voltage value is calculated using the ADC's corresponding precision. It's worth noting that the AD value is the analog-to-digital conversion value, and the ADC's precision is a preset precision. For example, if the preset ADC precision is 12 bits (0-4096) and the reference voltage is 3.3V, then AD = 4096 represents the AD value for measuring 3.3V. Each AD value = 3.3V / 4096 = 0.805mV. Assuming the acquired AD value is 3000, then the measured voltage = 3000 × 0.805mV = 2.41V. This method allows for the detection of voltage values ​​with the required precision. The analog-to-digital converter here includes the first and second analog-to-digital converters described in the above embodiments.

[0046] In this embodiment, after comparing the voltage difference with a preset voltage difference threshold, an implementation scheme for another comparison result is also provided, specifically, as follows: Figure 2 As shown, after step S120, that is, after comparing the voltage difference with a preset voltage difference threshold, the above method further includes:

[0047] Step S210: If the voltage difference is less than or equal to the voltage difference threshold, then perform a third sampling operation on the fuel sensor to obtain the second fuel level voltage.

[0048] Step S220: Use the second oil level voltage as the actual oil level voltage;

[0049] For steps S210-S220, it is understood that if the voltage difference is less than or equal to the voltage difference threshold, it means that the current supply voltage has not fluctuated, or the fluctuation is within an acceptable range and will not have a significant impact on or mislead the final result of the fuel level detection. Therefore, the fuel sensor is directly subjected to a third sampling operation to obtain the second fuel level voltage, which is then used as the actual fuel level voltage.

[0050] It should be understood that, for ease of understanding, the voltage sampling methods described above are first, second, and third. In practice, these should be understood as distinctions in sampling rounds, not as limitations on the sampling method. That is, the specific sampling operation in the third sampling operation can be the same as the first or second sampling operation. For example, the voltage value can be obtained by sampling and calculating the AD value through an ADC. It can also be selected and adjusted according to requirements.

[0051] In this embodiment, an exemplary implementation method is also provided for calculating a sampling ratio coefficient based on a second supply voltage and a standard voltage value, and for correcting the first oil level voltage using the sampling ratio coefficient, specifically including the following steps:

[0052] Calculate the multiple of the standard voltage value relative to the second supply voltage, and use the multiple as the sampling ratio coefficient;

[0053] The actual oil level voltage is obtained by multiplying the first oil level voltage by the sampling ratio coefficient.

[0054] In this embodiment, after obtaining the actual oil level voltage, the method further includes:

[0055] Calculate the actual resistance value of the fuel sensor based on the actual fuel level voltage;

[0056] Based on the actual resistance value, the preset resistance range of the fuel sensor is matched to determine the target resistance range that matches the actual resistance value.

[0057] Based on the correspondence between the resistance range and the preset oil level information, the target oil level information corresponding to the target resistance range is determined;

[0058] Display the target oil level information;

[0059] Regarding the above steps, it is important to understand that the preset resistance range can be a range corresponding to different oil level voltages determined in advance through calculation. It can be stored in the vehicle's database or the cloud database. At the same time, different resistance ranges correspond to preset oil level information. This oil level information can be understood as the information that corresponds to the detected oil level signal and needs to be displayed to the operator. It represents the oil level status corresponding to the oil level signal, so that the operator can understand the current oil level status based on the displayed oil level information.

[0060] Specifically, for example, in some embodiments, according to steps S110-140, the actual fuel level voltage 1V is obtained. Based on the actual fuel level voltage, the standard voltage value, and the resistance value corresponding to the standard voltage value, the actual resistance value corresponding to the actual fuel level voltage can be calculated. This actual resistance value is the resistance value of the current fuel sensor. The actual resistance value 1V is matched with at least one preset resistance value range. The target resistance value range is matched, for example, (0.5V, 1.5V), so that the actual resistance value 1V falls within the target resistance value range (0.5V, 1.5V). The fuel level information "current fuel level 1 / 2" corresponding to the target resistance value range (0.5V, 1.5V) is used as the target fuel level information and displayed. This display can be done through the vehicle's infotainment system, dashboard, or other display devices such as mobile phones, tablets, etc. For example, in some other embodiments, the target fuel level information is displayed by sending a text message "current fuel level 1 / 2" to the driver.

[0061] As described above, the fuel level voltage detection method for a vehicle provided in this application firstly samples the power supply voltage of the vehicle's power supply system to obtain a first power supply voltage. The voltage difference is calculated based on the first power supply voltage and a preset standard voltage value. This voltage difference is then compared with a preset differential voltage threshold. If the voltage difference is greater than the threshold, a second sampling operation is performed simultaneously on the power supply voltage and the fuel sensor to obtain a second power supply voltage and a first fuel level voltage. A sampling ratio coefficient is calculated based on the second power supply voltage and the standard voltage value, and the first fuel level voltage is corrected using this coefficient to obtain the actual fuel level voltage. This invention solves the problem in the prior art where abnormal data cannot be corrected, and where long-term fluctuations in the power supply voltage filter out a large amount of detection data, leading to abnormal fuel level signal detection and an inability to accurately and timely determine the vehicle's fuel level. This invention can accurately determine the fuel level voltage and correct large errors in real time, effectively avoiding the risk of fuel level monitoring interruptions due to long-term fluctuations in the power supply voltage. It enables continuous acquisition of the fuel level voltage, effectively improving the timeliness and accuracy of fuel level judgment. This method is characterized by its ingenious approach, strong vehicle adaptability, and low modification difficulty.

[0062] In one embodiment, this application also specifically provides a vehicle oil level voltage detection device, which corresponds one-to-one with the vehicle oil level voltage detection method in the above embodiments, such as... Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of a vehicle oil level and voltage detection device according to an exemplary embodiment of this application, including a first sampling module 301, a comparison module 302, a second sampling module 303, and a voltage correction module 304. Detailed descriptions of each module are as follows:

[0063] The first sampling module 301 is used to perform a first sampling operation on the power supply voltage of the vehicle power supply system to obtain the first power supply voltage.

[0064] The comparison module 302 is used to calculate the voltage difference based on the first supply voltage and the preset standard voltage value, and compare the voltage difference with the preset voltage difference threshold.

[0065] The second sampling module 303 is used to simultaneously perform a second sampling operation on the power supply voltage and the fuel sensor when the voltage difference is greater than the voltage difference threshold, so as to obtain the second power supply voltage and the first fuel level voltage.

[0066] The voltage correction module 304 is used to calculate the sampling ratio coefficient based on the second power supply voltage and the standard voltage value, and to correct the first oil level voltage using the sampling ratio coefficient to obtain the actual oil level voltage.

[0067] In this embodiment, the first sampling module further includes an analog-to-digital conversion unit;

[0068] The analog-to-digital converter unit is used for:

[0069] The vehicle power supply system is sampled using a first analog-to-digital converter to obtain a first analog-to-digital conversion value;

[0070] The first supply voltage is calculated based on the first preset accuracy and the first analog-to-digital converter value.

[0071] This application provides a vehicle fuel level voltage detection device. First, a first sampling operation is performed on the power supply voltage of the vehicle's power supply system to obtain a first power supply voltage. The voltage difference is calculated based on the first power supply voltage and a preset standard voltage value. This voltage difference is compared with a preset differential voltage threshold. If the voltage difference is greater than the threshold, a second sampling operation is performed simultaneously on the power supply voltage and the fuel sensor to obtain a second power supply voltage and a first fuel level voltage. A sampling ratio coefficient is calculated based on the second power supply voltage and the standard voltage value, and the first fuel level voltage is corrected using the sampling ratio coefficient to obtain the actual fuel level voltage. This invention solves the problem in the prior art where abnormal data cannot be corrected, and where long-term fluctuations in the power supply voltage filter out a large amount of detection data, leading to abnormal fuel level signal detection and an inability to accurately and timely determine the vehicle's fuel level. This invention can accurately determine the fuel level voltage and correct large errors in real time, effectively avoiding the risk of fuel level monitoring interruptions due to long-term fluctuations in the power supply voltage.
