Example one

Fig. 1 is a flowchart of an information detection method according to an embodiment of the present application, where the embodiment is applicable to a case where an E-gas architecture is applied in a vcu low-voltage power control, and the method may be executed by an information detection apparatus, where the information detection apparatus may be implemented in a form of hardware and/or software, and the information detection apparatus may be configured in an electronic device with an information detection capability. As shown in fig. 1, the method includes:

s110, acquiring an input voltage signal of a storage battery in the vehicle through a hardware monitoring layer of an E-Gas framework, and transmitting the information detection input voltage signal to a function monitoring layer.

The E-Gas architecture may have three components, which are a functional layer, a function monitoring layer, and a hardware monitoring layer, respectively, where the functional layer may have functions of implementing operation of device components, component monitoring, input or/and output variable diagnosis, controlling system reaction when a fault is detected, and the like, the function monitoring layer may have a function of detecting operation of the functional layer, and the hardware monitoring layer may have a function of detecting whether a program is correctly operated in a data question-answering process. The input voltage signal may be information such as the magnitude of voltage input into the battery, the type of current, and the input time.

Fig. 2 is a schematic diagram of the low-voltage power conversion and control of the electric vehicle according to the embodiment of the invention. Referring to fig. 2, when the electric vehicle is running or the battery is charged, the specification of the Current output from the high-voltage power battery is converted by a Direct Current converter (DCDC) into a specification of the Current that can be received and stored by the battery, thereby charging the battery of the electric vehicle. After receiving the high-voltage input of the high-voltage power battery, the DCDC transmits the real-time working state of the DCDC to the VCU through a CAN bus connected with a Vehicle Control Unit (VCU), and the VCU sends a DCDC enabling signal to Control the operation of the DCDC according to the real-time working state of the DCDC. When the VCU detects that the DCDC or the storage battery has faults, the current faults are transmitted to the instrument for displaying through a CAN bus connected with an instrument display (ICM).

Because the hardware monitoring layer has the function of detecting whether the program runs correctly in the data question-answering process, when the vehicle storage battery is charged, the hardware monitoring layer can acquire an input voltage signal of the storage battery in the vehicle, further determine the input voltage of the storage battery and data information such as current types, and transmit the acquired information to the function monitoring layer.

The input voltage signal of the vehicle storage battery is detected through the hardware monitoring layer of the E-Gas framework, so that the hardware monitoring layer is only responsible for acquiring data, the orderly operation of the system is ensured, and the acquired data, a specific method for acquiring the data and an execution main body are conveniently and clearly recorded.

And S120, detecting the information detection input voltage signal through the information detection function monitoring layer, and determining the zone bit information corresponding to the information detection input voltage signal according to the detection result.

The flag bit information may be information indicating whether the storage battery is faulty or not and a fault type when the storage battery is faulty, and a specific representation method of the flag bit information is not limited in the present invention.

After the function monitoring layer receives the input voltage signal sent by the hardware monitoring layer, the function monitoring layer detects the input voltage information, so that data carried in the input voltage signal is analyzed, and whether the storage battery breaks down or not is judged according to the data. And if the storage battery is detected to be in fault, further detecting the fault type of the storage battery, and determining corresponding zone bit information according to the detection result.

By detecting the input voltage signal and determining the zone bit information corresponding to the input voltage signal, the information acquisition and processing are positioned between two different levels, the possibility of interference in the acquisition and processing process is reduced, and the accuracy of data processing is further ensured.

In an alternative, before the information detecting input voltage signal is detected by the information detecting function monitoring layer, the information detecting method further includes:

and filtering the input voltage signal obtained by sampling in the current sampling period according to the input voltage signal obtained by sampling in the current sampling period, the input voltage signal obtained by sampling in the last sampling period, the sampling period and a preset time constant.

The sampling period may be a time interval in which the hardware monitoring layer twice acquires the input voltage signal of the battery in the vehicle. The predetermined time constant may be predetermined to determine whether the current output voltage is close to the output voltage of the current period and the previous period.

Due to the fact that the voltage may fluctuate abnormally or be located at a wave crest just during detection, the acquired data are wrong, and the accuracy of overall judgment is affected, filtering processing needs to be carried out on the input voltage signal, and therefore the situation is avoided.

After obtaining the input voltage signal sampled in the current sampling period, correlating the input voltage signal sampled in the current sampling period with the input voltage signal sampled in the previous sampling period and the sampling period, and drawing the correlation into table 1:

TABLE 1

Referring to table 1, in table 1, new _ value is used to indicate an input voltage signal sampled in a current sampling period, old _ value is used to indicate an input voltage signal sampled in a previous sampling period, and delta _ t is used to indicate a sampling period, where the new _ value and old _ value are in V (volt), the delta _ t is in S (second), all three data types are single data types, and except that a sampling period cannot be zero, no requirement exists in the data ranges of the new _ value and old _ value.

Drawing a table by using a preset time constant to obtain a table 2:

TABLE 2

Referring to table 2, the Time Constant is used to represent the preset Time Constant, and the data type of the preset Time Constant is also a single data type, and the unit of the preset Time Constant is the same as the sampling period, and is S (seconds), but the preset Time Constant has no requirement on the data range.

After the data in table 1 and table 2 are filtered, the filtered input voltage signal of the current sampling period is obtained, and the data is drawn into a table, so that table 3 is obtained:

TABLE 3

Referring to table 3, new _ ave is used to represent the filtered input voltage signal in the current sampling period, and the data type is a single data type, the unit of the filtered input voltage signal in the current sampling period is the same as the sampling period, and is S (seconds), and the filtered input voltage signal in the current sampling period has no requirement in the data range.

In one alternative, according to an input voltage signal sampled in a current sampling period, an input voltage signal sampled in a previous sampling period, a sampling period, and a preset time constant, filtering the input voltage signal sampled in the current sampling period, including steps A1-A3:

step A1, determining the sum of a sampling period and a preset time constant, and taking the ratio of an information detection sampling period to the information detection sum as a period parameter.

And A2, determining the difference value of the input voltage signal obtained by sampling in the current sampling period and the input voltage signal obtained by sampling in the previous sampling period.

And A3, determining the product of the information detection period parameter and the information detection difference value, and taking the sum of the information detection product and the input voltage signal obtained by sampling in the last sampling period as the input voltage signal of the current sampling period after filtering processing.

After an input voltage signal obtained by sampling in the current sampling period, an input voltage signal obtained by sampling in the previous sampling period, a sampling period and a preset time constant are obtained, calculating according to the obtained data, and filtering the input voltage signal obtained by sampling in the current sampling period, wherein the calculation formula is as follows:

output value = [ sampling period/(sampling period + time constant) ] (current period sampling value-previous period sampling value) + previous period sampling value

Namely new _ ave = [ delta _ t/(delta _ t + Time Constant) ] (new _ value-old _ value) + old _ value

And S130, outputting the information detection zone bit information to the vehicle so that the vehicle can determine the use strategy of the information detection input voltage signal according to the information detection zone bit information.

After the corresponding zone bit information is determined according to the input voltage signal, the function monitoring layer sends the obtained zone bit information to the vehicle. After the vehicle receives the zone bit information, the abnormal type of the storage battery in the period can be determined according to the obtained zone bit information, and then the use strategy of the input voltage signal is determined according to different abnormal types.

The use strategy of the input voltage signal is determined through the zone bit information, so that the data acquisition, the data processing and the data use are divided into three different levels, the influence caused by the operation of other two levels can be avoided when the data are used, and the accuracy of the data use is further ensured.

According to the technical scheme of the invention, the input voltage signal of the vehicle storage battery is detected by the hardware monitoring layer of the E-Gas framework, so that the hardware monitoring layer is only responsible for acquiring data, the orderly operation of the system is ensured, and the acquired data, the specific method for acquiring the data and the execution main body are conveniently and clearly recorded. By detecting the input voltage signal and determining the zone bit information corresponding to the input voltage signal, the information acquisition and processing are positioned between two different levels, the possibility of interference in the acquisition and processing process is reduced, and the accuracy of data processing is further ensured. The use strategy of the input voltage signal is determined through the zone bit information, so that the data acquisition, the data processing and the data use are divided into three different levels, the influence caused by the operation of other two levels can be avoided when the data are used, and the accuracy of the data use is further ensured. By using the steps, a software architecture which simultaneously meets the monitoring and functional safety requirements of a functional monitoring layer in the E-Gas and is developed based on a model is successfully constructed.

Example two

As shown in fig. 3, the method of this embodiment specifically includes the following steps:

The preset upper voltage limit may be a preset maximum voltage value that can be accepted by the storage battery, and the preset lower voltage limit may be a preset minimum voltage value that can be accepted by the storage battery. The first predetermined number of cycles may be a minimum number of cycles for determining that the input voltage signal is greater than the predetermined upper limit of the voltage. The second preset period number is the minimum period number for judging that the input voltage signal is smaller than the lower limit value of the preset voltage. The first predetermined flag may identify a condition that the input voltage signal is greater than a predetermined upper voltage limit. The second predetermined flag may identify the occurrence of the input voltage signal being less than the lower limit of the predetermined voltage.

When the voltage of the input voltage signal is judged, the problem that the judgment result is wrong when the abnormality occurs is judged only once, so that the continuous period number is judged besides the judgment of the voltage of the input voltage signal, and the misjudgment is further reduced.

The input voltage signal is processed and plotted into a table:

The present invention does not limit the data types and the specific numerical ranges of the above data.

After the input voltage signal is acquired, whether the input voltage signal is within a preset voltage range or not is judged, if the input voltage signal exceeds the maximum value within the preset voltage range and the continuously-occurring number exceeds a first preset period number, the voltage of the input voltage signal is determined to be overlarge, and then the upper limit fault flag position corresponding to the input voltage signal is set to be a first preset flag bit.

And if the input voltage signal exceeds the minimum value in the preset voltage range and the continuously appeared number exceeds the second preset period number, determining that the voltage of the input voltage signal is too small, and further setting the lower limit fault flag position corresponding to the input voltage signal as a second preset flag bit.

Referring to fig. 4, level1 is a functional layer, and level2 is a functional monitoring layer. In order to meet the requirement of functional safety diagnosis coverage rate, two hard-line acquisition channels are used for transmitting data, namely hard-line acquisition 1 and hard-line acquisition 2, so that two redundant acquisition channels are formed, and a first input voltage signal and a second input voltage signal exist in an input voltage signal. The invention does not limit the corresponding relation between the hard-line acquisition and the input voltage signal.

and step B1, determining a signal difference value of the first input voltage signal and the second input voltage signal, and comparing the information detection signal difference value with a preset constant.

And B2, if the difference value of the information detection signals is larger than a preset constant, setting the candidate fault flag bit as a third preset flag bit.

And B3, detecting the zone bit information corresponding to the input voltage signal according to the candidate fault zone bit determination information.

In table 9, i _ fault indicates the confirmed suspected fault flag, and the data type of i _ fault is single and has no range requirement. The invention does not limit the data type, range, unit and variable name of the suspected fault zone bit.

In an alternative, the flag bit information corresponding to the input voltage signal is detected according to the candidate fault flag bit determination information, and the method comprises the following steps of C1-C2:
