These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those of ordinary skill in the art in light of these embodiments are intended to be within the scope of the present invention.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
It is to be understood that although the terms actual, predicted, etc. may be used herein to describe various structures, these structures should not be limited by these terms. These terms are only used to distinguish one type of structure from another.
Fig. 1 shows a flowchart of a travel data saving method according to an exemplary embodiment of the present invention. The method of the embodiment may be applied to a terminal device (e.g., a vehicle-mounted terminal, a smart phone, a tablet computer, etc.), or may be applied to a server (e.g., a server cluster formed by one server or multiple servers, etc.). As shown in fig. 1, the method comprises the following steps S101-S104:
in step S101, recorded data of the current running process of the target vehicle is acquired.
Taking the terminal device as an example, in this embodiment, in the running process of the target vehicle, the terminal device may obtain the recorded data of the current running process of the target vehicle.
For example, the terminal device may obtain the recorded data of the current driving process of the target vehicle based on the bag recording function of the RoS system.
It should be noted that, in addition to the above-mentioned manner of obtaining the recorded data of the current driving process of the target vehicle by using the bag recording function of the RoS system, a person skilled in the art may also use other data recording manners in the related art based on actual needs, and the obtained recorded data is also applicable to the driving data storage method of the embodiment, which is not limited in this embodiment.
In step S102, the current driving process is evaluated to obtain an evaluation result.
In this embodiment, after the terminal device obtains the recorded data of the current driving process of the target vehicle, the current driving process may be evaluated to obtain an evaluation result.
For example, after the recorded data of the current driving process of the target vehicle is obtained, in order to determine whether the recorded data needs to be stored, the current driving process of the target vehicle may be evaluated by using a driving process evaluation method in the related art, and then a corresponding evaluation result may be obtained.
In an embodiment, the driving process evaluation manner may be set by a developer based on actual business needs, which is not limited in this embodiment.
In another embodiment, the above-mentioned manner of evaluating the current driving process can also be referred to the following embodiment shown in fig. 3, which is not described in detail herein.
In step S103, it is determined whether the evaluation result satisfies the retained data condition: if yes, go to step S104; if not, executing step S105;
in step S104, the recording data is saved.
In step S105, the recorded data is discarded.
In this embodiment, when the terminal device evaluates the current driving process to obtain an evaluation result, it may be determined whether the evaluation result meets a data retention condition, and if it is determined that the evaluation result meets the data retention condition, the recorded data may be stored, for example, the recorded data may be stored in a hard disk space and/or a memory space; conversely, if it is determined that the evaluation result does not satisfy the data retention condition, the recorded data may be discarded, i.e., the recorded data is not retained in the hard disk space and/or the memory space.
The condition for retaining data may be set by a person skilled in the art based on actual service needs, which is not limited in this embodiment.
For example, if a person skilled in the art needs to analyze the abnormal driving condition and cause of the target vehicle based on the recorded data, the reserved data condition may be set as a condition for abnormal driving.
According to the technical scheme, the recorded data of the current running process of the target vehicle are obtained, the current running process is evaluated to obtain the evaluation result, and then when the evaluation result meets the condition of data retention, the recorded data are stored, whether the obtained recorded data are retained or not can be determined based on the quality of the current running process of the target vehicle, the pertinence of storing the recorded data can be improved, the occupation of a hard disk space and a memory space is reduced, the running abnormal condition of the vehicle can be directly analyzed based on the stored data subsequently, data screening is not needed, and the working difficulty of running abnormal analysis can be reduced.
Fig. 2 shows a flowchart of a travel data saving method according to yet another exemplary embodiment of the present invention; the method of the embodiment may be applied to a terminal device (e.g., a vehicle-mounted terminal, a smart phone, a tablet computer, etc.), or may be applied to a server (e.g., a server cluster formed by one server or multiple servers, etc.). As shown in fig. 2, the method comprises the following steps S201-S205:
in step S201, recorded data of the current running process of the target vehicle is acquired.
In step S202, the current driving process is evaluated to obtain an evaluation result.
In step S203, the evaluation score value is compared with a set score threshold value.
In this embodiment, when the terminal device obtains the recorded data of the current driving process of the target vehicle, evaluates the current driving process, and obtains an evaluation result, it may be determined whether the evaluation result satisfies a data retention condition.
Wherein, the evaluation result may comprise an evaluation score value. For example, after the current driving process is evaluated and an evaluation score value is obtained, the evaluation score value may be compared with a set score threshold value to obtain a comparison result.
It should be noted that the above-mentioned set score threshold may be set by a developer according to actual business needs, which is not limited in this embodiment.
In step S204, if the evaluation score value is higher than or equal to the set score threshold, it is determined that the evaluation result satisfies a retained data condition.
In this embodiment, after the evaluation score value is compared with the set score threshold to obtain a comparison result, if the comparison result indicates that the evaluation score value is higher than or equal to the set score threshold, it may be determined that the evaluation result satisfies the condition of retaining data. On this basis, the subsequent step of saving the recorded data may be performed. On the contrary, if the evaluation score value represented by the comparison result is lower than the set score threshold, it may be determined that the evaluation result satisfies a condition of not retaining data, so that the recorded data may not be saved.
In step S205, the recorded data is saved.
For the explanation and explanation of steps S201 to S202 and step S205, reference may be made to the embodiment shown in fig. 1, which is not described herein again.
According to the technical scheme, the evaluation score value is compared with the set score threshold value, and when the evaluation score value is higher than or equal to the set score threshold value, the evaluation result is determined to meet the condition of data retention, so that whether the evaluation result of the current driving process meets the condition of data retention can be accurately judged, whether the acquired recorded data is retained can be determined based on the quality of the current driving process of the target vehicle, the recorded data can be stored in a targeted manner, the occupation of a hard disk space and a memory space can be reduced, the driving abnormal condition of the vehicle can be directly analyzed based on the stored data, data screening is not needed, and the working difficulty of driving abnormal analysis can be greatly reduced.
Fig. 3 shows a flow chart of how a current driving process is evaluated according to an exemplary embodiment of the invention; the present embodiment exemplifies how to evaluate the current running process on the basis of the above-described embodiments. As shown in fig. 3, the evaluating the current driving process in step S102 to obtain an evaluation result may include the following steps S301 to S302:
in step S301, the driving parameters of each sub-path in the current driving process are acquired.
In this embodiment, after or before the recorded data of the current driving process of the target vehicle is obtained, the driving parameters of each sub-path in the current driving process may be obtained.
The driving parameters may include speed, acceleration, path point, and the like of each sub-path in the current driving process, which is not limited in this embodiment.
In step S302, at least one driving process evaluation indicator of the current driving process is determined based on the driving parameters.
In this embodiment, after obtaining the driving parameters of each sub-path in the current driving process, at least one driving process evaluation index of the current driving process may be determined based on the driving parameters.
In one embodiment, the running process evaluation index includes at least one of:
(1) indicators for characterizing whether a collision occurs, such as: 1 (representing "yes") or 0 (representing "no");
(2) deviation indicators of waypoints from lane centre line, e.g. exWherein x is the deviation of the waypoint from the lane center line;
(3) distance index of the target vehicle from the obstacle, e-yWhere y is the distance of the target vehicle from the obstacle.
It is to be noted that the smaller the value of x, the safer the value of x, and the larger the value of y, and thus when determining the index, it can be determined as exAnd e-y。
(4) An indicator for characterizing whether the target vehicle is speeding, such as: 1 (representing "yes") or 0 (representing "no");
(5) an index for characterizing whether the target vehicle violates a set traffic rule, such as: 1 (indicating yes) or 0 (indicating no).
The set traffic rules may be set by developers based on actual business needs or traffic regulation criteria in related scenes, such as setting to run traffic lights, pressing solid lines, walking lanes, and the like, which is not limited in this embodiment.
In step S303, the evaluation value of the current running course is determined based on the at least one running course evaluation index.
In the present embodiment, after determining at least one travel process evaluation index of the current travel process based on the travel parameters, the evaluation value of the current travel process may be determined based on the at least one travel process evaluation index.
For example, when the running process evaluation indexes (1) to (5) are determined, the running process evaluation indexes may be processed and merged to obtain the evaluation value of the current running process. The processing and fusing manner may include normalization, weighted sum, and the like, which is not limited in this embodiment.
It should be noted that, in the running process evaluation indexes (1) to (5), if the values of the items (1), (4) and (5) are greater than 0, it can be determined that the current running process is very poor, that is, the running safety is very poor, and therefore, in the subsequent fusion process, the specific gravity of the three items can be set to be higher; if the numerical value of (2) is larger, the current driving process can be determined to be poor, so that the specific gravity of the item can be set to be a medium specific gravity in the subsequent fusion process; if the value of (3) is larger, it can be determined that the current driving process is better, and therefore, in the subsequent fusion process, the specific gravity of this item can be set to be a medium specific gravity.
In another embodiment, the above-mentioned manner of determining the evaluation value of the current driving process based on the at least one driving process evaluation index may be referred to the following embodiment shown in fig. 4, and will not be described in detail herein.
As can be seen from the above technical solutions, in this embodiment, by obtaining the driving parameters of each sub-path in the current driving process, determining at least one driving process evaluation index of the current driving process based on the driving parameters, and determining the evaluation value of the current driving process based on the at least one driving process evaluation index, the current driving process can be evaluated to obtain an accurate and reasonable evaluation result, a foundation can be laid for subsequently determining whether the evaluation result meets a condition of retaining data, and determining whether to retain the obtained recorded data based on the quality of the current driving process of the target vehicle, the recorded data can be stored in a targeted manner, occupation of a hard disk space and a memory space can be reduced, and subsequently, driving abnormal conditions of the vehicle can be directly analyzed based on the stored data without data screening, the difficulty of the running abnormity analysis can be greatly reduced.
Fig. 4 shows a flow chart of how the evaluation value of the current driving process is determined based on the at least one driving process evaluation index according to an exemplary embodiment of the present invention; the present embodiment exemplifies how to determine the evaluation value of the current running course based on the at least one running course evaluation index on the basis of the above-described embodiments. As shown in fig. 4, the determining the evaluation value of the current driving process based on the at least one driving process evaluation index in step S303 may include the following steps S401 to S402:
in step S401, a weighted sum of the at least one driving process evaluation index is calculated.
In this exemplary embodiment, after determining at least one driving process evaluation indicator of the current driving process on the basis of the driving parameters, a weighted sum of the at least one driving process evaluation indicator may be calculated.
For example, after determining the first driving process evaluation index, the second driving process evaluation index, the third driving process evaluation index, the fourth driving process evaluation index and the fifth driving process evaluation index of the current driving process, the first driving process evaluation index, the second driving process evaluation index, the third driving process evaluation index, the fourth driving process evaluation index and the fifth driving process evaluation index may be weighted and calculated to obtain a weighted and calculated result.
The first to fifth driving process evaluation indexes may be indexes (1) to (5) in the embodiment shown in fig. 3, and are not described herein again.
In an alternative embodiment, before weighting and calculating the running process evaluation indexes, normalization processing may be performed on the running process evaluation indexes, and then weighting and calculation may be performed based on the running process evaluation indexes after the normalization processing.
In step S402, the evaluation value of the current running course is determined based on the weighted sum.
In this embodiment, after calculating the weighted sum of the at least one travel process evaluation index, the travel process evaluation value of the current travel process may be determined based on the weighted sum.
For example, the value of the weighted sum may be determined as the running course evaluation value of the current running course.
As can be seen from the above technical solutions, in the present embodiment, by calculating the weighted sum of the at least one driving process evaluation index and determining the driving process evaluation value of the current driving process based on the weighted sum, at least one driving process evaluation index can be fused, so that the driving process evaluation value of the current driving process can be determined based on the fusion result of the at least one driving process evaluation index, and the accuracy of determining the driving process evaluation value can be improved.
