Embodiment 1

[0035] Please refer to figure 1 , figure 1 It is a schematic flowchart of a data extraction method according to an embodiment of the present invention.

[0036] Since the vehicle condition information within the future driving mileage cannot be known in advance, the current vehicle control strategy considers the current state of the vehicle and controls the vehicle according to the preset control rules. Optimal decision-making depends entirely on the rationality of the preset control strategy.

[0037]The inventor found that passenger cars are usually used for commuting such as commuting to get off work. The vehicle condition parameters during the path change along the way, such as vehicle speed, engine speed, etc., and the global operating condition spectrum of the fixed path is formed as the input of the vehicle control management strategy. The vehicle control management strategy can give the global optimal control for the fixed path, which will Significantly improve the ov...

[0052] Please refer to Figure 2 to Figure 9 ,in, figure 2 is the driving trajectory map of the vehicle according to an embodiment of the present invention; image 3 is a schematic diagram of a fixed path of a vehicle according to an embodiment of the present invention; Figure 4 is a schematic diagram of vehicle speed data of a vehicle according to an embodiment of the present invention; Figure 5 is a schematic diagram of engine water temperature data of a vehicle according to an embodiment of the present invention; Image 6 is a schematic diagram of vehicle speed data fitting of a vehicle according to an embodiment of the present invention; Figure 7 is a schematic diagram of fitting the engine water temperature data of the vehicle according to an embodiment of the present invention; Figure 8 is a schematic diagram of the mapping relationship between vehicle speed and travel time according to an embodiment of the present invention; Figure 9 It is a schematic diagram...

Embodiment 3

[0069] Please refer to Figure 10 , Figure 10 It is a schematic structural diagram of a vehicle control system according to an embodiment of the present invention.

[0070] This embodiment provides a vehicle control system, the vehicle control system includes a fixed path identification module 2 and a global operating condition spectrum extraction module 3, wherein the fixed path identification module 2 is used for correlation according to historical driving data of the vehicle at least one fixed path is identified; the global operating condition spectrum extraction module 3 is configured to obtain a global operating condition spectrum according to the historical driving data and the at least one fixed path, and the global operating condition spectrum includes vehicle condition parameters and travel characteristics A mapping relationship between at least a part of the parameters. The global operating condition spectrum extraction module 3 is further configured to identify t...

Abstract

The invention provides a data extraction method, a vehicle service method, a vehicle control system and a storage medium. The data extraction method comprises the following steps: identifying at least one fixed path according to the correlation of historical driving data of a vehicle; and obtaining a global working condition spectrum according to the historical driving data and the at least one fixed path, wherein the global working condition spectrum comprises at least one part of mapping relation between the vehicle condition parameters and the advancing characteristic parameters. Through the configuration, the change rule of the vehicle condition parameter along the way when the vehicle travels on the fixed path can be obtained based on the historical data of the Internet of Vehicles, so the vehicle condition parameter in the future travelled distance is effectively predicted, a data basis is provided for subsequent control strategy development, and the problems that in the prior art, the utilization rate of Internet of Vehicles data is not high, and a vehicle control algorithm cannot obtain vehicle condition parameters in the future mileage in advance are solved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a data extraction method, a vehicle service method, a vehicle control system and a storage medium. Background technique [0002] At present, countries around the world are actively promoting the research and development and application of Internet of Vehicles technology. my country is also vigorously developing cellular-based Internet of Vehicles (ie Cellular-V2X, C-V2X for short) technology, and has achieved standards, core technologies and industries. Long-term development, in a leading position. The Internet of Vehicles realizes the sharing and exchange of data such as vehicles, roads, people, and clouds. It includes multiple data sources, and different data sources can collect different data. [0003] However, the current data mining of the fixed path of the Internet of Vehicles only stays at the level of vehicle trajectory analysis. The specific method is to collect the tra...
