Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
It can be known from the background art that when the diesel vehicle and the gasoline vehicle are annual inspected, if the number of the unfinished items in the ready state exceeds 2, the vehicle owner needs to drive the vehicle sufficiently and then perform the recheck. However, vehicles operating in extreme areas and vehicles with special applications are difficult to meet the conditions for monitoring function operation, and failure to monitor results in failure of the vehicle, so that the vehicle can not be set in a ready state, and finally the vehicle can not pass annual inspection.
Therefore, an embodiment of the present invention provides a method and a system for setting a ready state under an extreme condition, where a target combination condition corresponding to a fault is selected from a plurality of combination conditions, and when an operating state of a target vehicle meets a preset operating condition and the fault is determined to be in the extreme condition of the target combination condition, whether the fault is forcibly ready is determined by using an operating process count and/or an engine operating time count of the target vehicle. And if the fault is forced to be ready, setting the ready state into a ready state, so that the vehicle running under special application and extreme area conditions can meet the national standard and pass annual inspection in time.
It should be noted that for some faults, the fault is monitored only under specific conditions, so that the ready state of the fault can be set to the ready state, for example: selective Catalytic Reduction (SCR) catalyst only works when exhaust gas is higher than a certain temperature, and only the SCR catalyst works to convert nitrogen oxide, and then the conversion efficiency of nitrogen oxide can be calculated, and if the SCR catalyst does not work, the conversion efficiency of nitrogen oxide cannot be calculated (nitrogen oxide is not converted at this time), and the effect of the SCR catalyst cannot be embodied, that is, for the aforementioned failure, the ready state of the failure can be set only by passing monitoring.
It is to be understood that the setting of the ready state to the ready state (also referred to as ready) in the embodiment of the present invention refers to: the status of the operation of a certain monitoring function or group of monitoring functions since the last time the fault information was cleared by an external request or command (e.g., by an OBD diagnostic).
Referring to fig. 1, a flowchart of a setting method for a ready state under an extreme condition according to an embodiment of the present invention is shown, where the setting method includes:
step S101: and combining a plurality of preset extreme conditions to obtain a plurality of combined conditions.
In the process of implementing step S101, various extreme conditions are preset, such as: extreme conditions such as extremely high altitude (altitude above an altitude threshold) and extremely low ambient temperature (ambient temperature below a temperature threshold) are set.
Combining the extreme conditions to obtain a plurality of combination conditions, wherein each combination condition at least comprises one extreme condition, namely each combination condition is obtained by combining one or more extreme conditions.
Such as: assuming that an extreme condition 0, an extreme condition 1, and an extreme condition 2 are set, the aforementioned 3 extreme conditions are combined to obtain a combined condition 1 (obtained by combining the extreme condition 0 and the extreme condition 1), a combined condition 2 (obtained by combining the extreme condition 0 and the extreme condition 2), and a combined condition 3 (obtained by combining the extreme condition 1 and the extreme condition 2).
Preferably, after obtaining a plurality of combination conditions, each combination condition is mapped to a corresponding Trigger (TRG), that is, each TRG corresponds to a combination condition.
Step S102: and determining a target combination condition corresponding to the fault of the target vehicle in the multiple combination conditions.
In the process of specifically implementing step S102, a TRG corresponding to a failure of the target vehicle is randomly selected from the plurality of TRGs, and the combination condition corresponding to the selected TRG is determined as the target combination condition corresponding to the failure.
That is, for each failure, the failure may select an arbitrary combination condition as a target combination condition.
Step S103: and if the running state of the target vehicle is determined to accord with the preset running condition and the fault is determined to be in the extreme condition of the target combination condition, determining whether the fault is in forced readiness under the extreme condition of the target combination condition or not by utilizing the operation process count and/or the engine running time count of the target vehicle under the fault according to the fault monitoring strategy. If the fault is forced to be ready under the extreme condition of the target combination condition, step S104 is executed.
It should be noted that, each fault sets a corresponding operation process threshold and an engine operation time threshold, that is, the operation process thresholds may be different for different faults, and the engine operation time thresholds may be different for different faults.
It is understood that the operation process refers to: the engine power-on-engine start-engine stop is 1 operation process, that is, 1 operation process is composed of three operations of engine power-on, engine start and engine stop.
From the foregoing, a TRG is randomly selected for each fault, and each fault corresponds to an operating process threshold and an engine run time threshold, for a specific example, see table 1 below.
Table 1:
as can be seen from the above table 1, the TRGs corresponding to different faults correspond to different combination conditions, and each fault sets an operation process threshold and an engine operating time threshold corresponding to the fault.
In the process of implementing step S103 specifically, after the target vehicle starts the engine, the normal operation time length of the engine is obtained, and if the normal operation time length is greater than or equal to the normal operation time threshold value, that is, after the engine is started successfully and operates for a certain time, it is determined that the operation state of the target vehicle meets the preset operation condition. When the engine of the target vehicle is successfully started and operated for a certain time, and the fault is determined to be in an extreme condition of the target combination conditions, the operating process count and/or the engine operation time count of the target vehicle under the fault are accumulated.
Such as: in conjunction with the contents shown in table 1, the combined condition corresponding to the fault DFC _ N1 is combined condition 0, and assuming that the combined condition 0 is obtained by combining the extreme condition 1 and the extreme condition 2, when the engine is successfully started and operated for a certain time, and it is determined that the extreme condition 1 and the extreme condition 2 are satisfied, that is, the engine is successfully started and operated for a certain time and it is determined that the fault DFC _ N1 is under the extreme condition 1 and the extreme condition 2, the operating process count and/or the engine operating time count of the target vehicle under the fault are accumulated.
After the operating process count and/or the engine operating time count of the target vehicle under the fault are accumulated, whether the fault is forcibly ready under the extreme condition of the target combination condition is determined by using the operating process count and/or the engine operating time count of the target vehicle under the fault according to the monitoring strategy of the fault.
It should be noted that, because the monitoring strategies for different faults are different, in the process of determining whether the fault is in a forced ready state under the extreme condition of the target combination condition, the judgment may be performed by using only the operation process count under the fault, or only using only the engine operation time count under the fault, or using both the operation process count and the engine operation time count under the fault, and the specific judgment process refers to the following three cases.
In the first case: and if the fault monitoring strategy is a first appointed type monitoring strategy, when the operation process count of the target vehicle under the fault is larger than the operation process threshold value and the engine running time count is larger than the engine running time threshold value, determining that the fault is forced to be ready under the extreme condition of the target combination condition.
In the second case: the second specified type monitoring strategy indicates that monitoring is only allowed once per driving cycle of the target vehicle, the operation process threshold corresponding to the fault corresponding to the second specified type monitoring strategy is set according to the regulation, and the engine operation time threshold is calibrated to be the maximum value. In this case, if the monitoring policy for the fault is the second specified type of monitoring policy, when the operational process count is greater than the operational process threshold under the fault, it is determined that the fault is forcibly ready under the extreme condition of the target combination condition.
In the third case: similar to the second case, for the fault corresponding to the third designated type of monitoring strategy, only the running time count of the engine can be selected by a calibration means to judge whether to be ready forcibly. In this case, if the monitoring policy for the fault is a third specified type of monitoring policy, when the engine run time count under the fault is greater than the engine run time threshold, it is determined that the fault is forcibly ready under the extreme conditions of the target combination conditions.
Step S104: the ready state of the fault is set to a ready state.
In the process of implementing step S104 specifically, after the fault is forced to be ready under the extreme conditions of the target combination condition, the ready state of the fault is set to the ready state.
Through the contents of the above steps S101 to S104, the respective failures are processed accordingly.
According to the content of the above steps S101 to S104, an execution logic of the setting method of the ready state under the extreme condition is designed, the execution logic is shown as an execution logic schematic diagram shown in fig. 2, and specific content in the execution logic schematic diagram can refer to the content of each step, which is not described herein again.
It should be noted that the content shown in fig. 2 is only for example, that is, the content shown in fig. 2 is only a certain example corresponding to the embodiment of the present invention, and for more detailed content, the content of each step may be referred to, and is not described again here.
In the embodiment of the invention, a target combination condition corresponding to the fault is selected from a plurality of combination conditions, and when the running state of the target vehicle meets the preset running condition and the fault is determined to be in the extreme condition of the target combination condition, whether the fault is in forced readiness is determined by utilizing the operation process count and/or the engine running time count of the target vehicle. If the fault is forced to be ready, the ready state is set to be ready state, so that the vehicle running under the special application and extreme area condition can not only meet the national standard, but also pass the annual inspection in time.
Referring to fig. 3, a flowchart of obtaining a plurality of combination conditions according to step S101 in the foregoing embodiment of the present invention is shown, and includes:
step S301: various preset extreme conditions are acquired.
In the process of implementing step S301, reference may be made to the content in step S101 of fig. 1 in the embodiment of the present invention, and details are not repeated herein.
Step S302: and combining the multiple preset extreme conditions according to the preset different masks to obtain multiple combined conditions.
In the process of implementing step S302, a plurality of sets of extreme conditions are released by using different masks, and the plurality of sets of extreme conditions are combined to obtain a plurality of combination conditions.
To better explain how the sets of extreme conditions are combined using different masks, the logic diagram of the implementation of obtaining the combined conditions shown in fig. 4 is used for illustration.
In fig. 4, logical operations are performed by combining extreme conditions 0 (abbreviated as condition 0) to extreme conditions n (abbreviated as condition n) with masks 0 to m, respectively, to obtain combination conditions 0 to m.
In the embodiment of the invention, the multiple groups of extreme conditions are combined by using different masks to obtain multiple combined conditions, a target combined condition corresponding to the fault is selected from the multiple combined conditions, and when the running state of the target vehicle meets the preset running condition and the fault is determined to be in the extreme condition of the target combined condition, whether the fault is forced to be ready is determined by using the operation process count and/or the engine running time count of the target vehicle. If the fault is forced to be ready, the ready state is set to be ready state, so that the vehicle running under the special application and extreme area condition can not only meet the national standard, but also pass the annual inspection in time.
