In the above embodiment, the vehicle history running information may be collected through the vehicle-mounted TBOX terminal, where the vehicle history running information is generally the running status of the vehicle, mainly includes the start-stop condition of the hydrodynamic retarder of the vehicle, the vehicle speed, the vehicle coordinates, and the like, and these information are generally uploaded to the internet of vehicles platform for processing in the form of a message after being collected.
After receiving the message, the internet of vehicles platform analyzes the message, and because the collected data is more, invalid and wrong information is inevitably generated, the analyzed data needs to be processed, and the invalid and wrong information is removed, so that the data can be accurately aggregated in the follow-up process.
The aggregation of the non-impurity vehicle running information, the map information, the historical load information, the historical weather information and the historical vehicle attribute information is to correlate the related information at the same time, so that the relation between the running state of the vehicle, the running environment and the start and stop of the hydrodynamic retarder is known, and the aggregated data, namely a vehicle aggregation information table, is stored in a form of a table.
And inquiring the vehicle aggregation information table according to the vehicle aggregation information table, the current running information of the vehicle, the current weather information and the current vehicle attribute information, so as to know the start-stop condition of the hydraulic retarder of the vehicle under the past condition, and realize the control of the start-stop of the hydraulic retarder.
Compared with the prior art, the method for controlling the start and stop of the hydraulic retarder comprises the following steps: preprocessing the historical driving information of the vehicle to obtain the driving information of the vehicle without impurities; aggregating the impurity-free vehicle running information, map information, historical load information, historical weather information and historical vehicle attribute information to obtain a vehicle aggregation information table; and controlling the start and stop of the hydraulic retarder according to the vehicle aggregation information table, the current running information of the vehicle, the current weather information and the current vehicle attribute information. According to the method, the historical driving information, the map information, the historical load information, the historical weather information and the historical vehicle attribute information of the vehicle are aggregated, the start-stop condition of the historical hydrodynamic retarder of the vehicle is known, the start-stop condition of the corresponding historical hydrodynamic retarder is inquired according to the information and the environment information when the vehicle actually drives, and accordingly the start-stop of the hydrodynamic retarder corresponding to the current driving information, the current weather information and the current vehicle attribute information of the vehicle is controlled, the influence of various factors on the start-stop of the hydrodynamic retarder is considered, accurate control of the start-stop of the hydrodynamic retarder is achieved, and driving experience of a driver is improved.
In some embodiments of the invention, the vehicle history travel information includes historical vehicle speed information, historical hydrodynamic retarder start-stop information, and vehicle history coordinate information; preprocessing the historical driving information of the vehicle to obtain the driving information of the vehicle without impurities, comprising the following steps:
removing historical vehicle speed information outside a preset vehicle speed range, and filtering historical hydraulic retarder start-stop information;
and calculating the abnormal coordinate points according to the historical coordinates of the vehicle, and eliminating the abnormal coordinate points.
In the above embodiment, the mode of preprocessing the historical driving information of the vehicle includes, but is not limited to, using a flink real-time stream analysis, and the vehicle speed is generally in a fixed range during normal driving of the vehicle, so that the vehicle speed not in the range is an abnormal value and needs to be removed. The hydrodynamic retarder is generally in two states of starting and stopping, wherein 0 is used for indicating that the hydrodynamic retarder is stopped, 1 is used for indicating that the hydrodynamic retarder is started, and FF is used for indicating abnormal signals, so that signals except 0 and 1 in the hydrodynamic retarder need to be removed.
When data is collected, all data in one collection time point is generally taken as a group of data, and meanwhile, the start-stop condition, the vehicle speed, the vehicle coordinates and the like of the hydrodynamic retarder of the vehicle are included, so that when certain information is abnormal, all information collected at the time point needs to be removed.
In some embodiments of the present invention, calculating a coordinate outlier from a vehicle history coordinate and eliminating the coordinate outlier includes:
calculating a theoretical running distance of the vehicle according to the acquisition time of the adjacent vehicle historical coordinates and the historical vehicle speed information;
and determining and eliminating the abnormal coordinate points according to the theoretical driving distance of the vehicle and the actual driving distance of the vehicle.
In the above embodiment, the abnormal coordinate point needs to be determined by calculation, and since there is a collection time when the vehicle running information is collected, the time interval between two adjacent vehicles can be determined according to the adjacent collection time, then the theoretical running distance of the vehicle is calculated according to the speed of the vehicle, the actual running distance of the vehicle is determined according to the coordinate information of the vehicle, if the difference between the theoretical running distance and the actual running distance is large, the abnormal coordinate information of the vehicle is considered to be the abnormal coordinate point, and the abnormal coordinate point needs to be removed.
In the invention, if the theoretical running distance of the vehicle is greater than or less than 1.2 times of the actual running distance of the vehicle, the actual running distance of the vehicle is considered unreliable, the corresponding coordinate information of the vehicle is abnormal, and the abnormal points of the coordinates need to be removed.
Referring to fig. 2, fig. 2 is a flowchart of an embodiment of step S102 in fig. 1 provided by the present invention, in some embodiments of the present invention, the aggregation of the non-hybrid vehicle driving information, the map information, the historical load information, the historical weather information and the historical vehicle attribute information to obtain a vehicle aggregation information table includes:
s201, dividing map information into a plurality of grids; the grid contains non-impurity vehicle running information, historical load information and historical vehicle attribute information;
s202, filtering information when the hydraulic retarder is stopped according to historical hydraulic retarder start-stop information;
s203, aggregating and filtering the travel information, map information, historical load information, historical weather information and historical vehicle attribute information of the non-impurity vehicle to obtain historical thermal data;
s204, matching the historical thermal data with map information to obtain a vehicle aggregation information table.
In the above embodiment, since the area where the vehicle travels is large, the map of the vehicle traveling area is segmented, so as to determine the traveling situation of the vehicle, and the grid divided by the map information is generally a square grid, so that the map area can be uniformly divided, the traveling situation of the vehicle in each grid area can be known, and the collected non-impurity vehicle traveling information, history load information and history vehicle attribute information need to be written into the corresponding square grid.
The method comprises the steps of filtering the non-impurity vehicle running information according to the historical starting and stopping information of the hydraulic retarder, wherein the vehicle running information is only needed when the hydraulic retarder of the vehicle is started, and the hydraulic retarder of the vehicle is not needed to be controlled when the hydraulic retarder of the vehicle is stopped, so that the part of information is not needed, only the time when the hydraulic retarder is started is needed to be known, and the hydraulic retarder is in a closed state in the rest time.
The non-miscellaneous vehicle driving information, the map information, the historical load information, the historical weather information and the historical vehicle attribute information are all related to the starting and stopping of the hydraulic retarder of the vehicle, so that the information needs to be related, the filtering refers to filtering out the information with low reference value, namely, the hydraulic retarder is started in a part of time, and therefore, the hydraulic retarder is not required to be started in the part of time by default.
The historical thermal data is matched with the Internet information through a map API, wherein the map API is an API for embedding the map into a webpage through JavaScript (or other languages). The API provides a number of utilities to process maps and add content to the map through various services, enabling the creation of fully functional map applications on a web site.
Referring to fig. 3, fig. 3 is a flowchart illustrating an embodiment of step S203 in fig. 2 according to the present invention, and in some embodiments of the present invention, the map information includes road codes; aggregating and filtering the non-impurity vehicle driving information, the map information, the historical load information, the historical weather information and the historical vehicle attribute information to obtain historical thermal data, wherein the method comprises the following steps of:
s301, aggregating historical load information, historical weather information and historical vehicle attribute information to obtain an initial aggregation point;
s302, filtering the initial polymerization point according to the historical start-stop information of the hydraulic retarder to obtain a transition polymerization point;
and S303, aggregating road codes, transition aggregation points and vehicle history coordinates to obtain history thermal data.
In the above embodiment, the initial aggregation point is obtained by aggregating the historical load information, the historical weather information and the historical vehicle attribute information through the clustering function, and it should be noted that, the clustering function in the present invention may use a spatial clustering method function of postgis to implement information clustering, including but not limited to st_clusteridbscan function.
The historical load information is whether the load is carried, the historical weather information is whether the weather is rainy or snowy, and the historical vehicle attribute information comprises inherent attribute information of vehicles such as types of vehicles and engine models.
When the situation that the hydraulic retarder is started in the initial aggregation point obtained by aggregation of the same vehicle driving information on the same grid is not more than 20%, the situation is considered to be low-density, namely the situation that the hydraulic retarder is not started under default conditions is considered to be unnecessary, and therefore the corresponding initial aggregation point is filtered, and the transitional aggregation point is obtained.
In this embodiment, redis may be used, or other memory database components may be used, to splice road codes, historical vehicle attribute information, historical load information, and historical weather information into key names. For example, the historical vehicle attribute information is represented by three-bit English typ, the historical load information is represented by 1 or 0, and the key name format is as follows: 'roadnum.typ.0.0', and adding coordinate information corresponding to the vehicle to the stored key by using geoadd to aggregate to obtain historical thermal data.

s403, controlling the start and stop of the hydraulic retarder according to the historical start and stop information of the hydraulic retarder and the current running information of the vehicle.
In the above embodiment, the current running information of the vehicle may also be collected in real time through the vehicle-mounted TBOX terminal, and after collection, the current running information needs to be uploaded to the internet of vehicles platform in the form of a message for unified processing. It should be noted that the information collected each time will also be historical information, which is used to provide a reference for the start-stop control of the hydrodynamic retarder of the future vehicle.
According to the current position information, the current weather information and the current vehicle attribute information of the vehicle, the vehicle aggregation information table can be queried to determine the start-stop information of the historical hydraulic retarder when the weather information and the vehicle attribute information are the same within a preset distance from the current position information of the vehicle, namely whether the hydraulic retarder is started or not.
Under the historical condition, when the same vehicle attribute information, weather information and vehicle position information are used, the hydraulic retarder is started, so that the hydraulic retarder is required to be started under the current condition, and if the hydraulic retarder is not started, the hydraulic retarder is not required to be started under the current condition.
Referring to fig. 5, fig. 5 is a flowchart of an embodiment of step S402 in fig. 4 provided by the present invention, in some embodiments of the present invention, determining historical hydraulic retarder start-stop information according to a vehicle aggregation information table within a predetermined distance of a vehicle' S current location information, current weather information, and current vehicle attribute information, includes:
