Method and system for acquiring vehicle typical working condition

Abstract

The invention discloses a method for acquiring a vehicle typical working condition, and the method is used for efficiently and accurately acquiring the vehicle typical working condition. The method comprises the following steps of: collecting GPS (Global Positioning System) information and operating characteristic data in a vehicle running process; converting longitude and latitude data in a vehicle running road section into road information of the vehicle running road section according to the received GPS information; receiving and storing the vehicle information, the road information and the corresponding operating characteristic data; sectioning the operating characteristic data which are continuous in time and consistent in vehicle information and road information; establishing an average vehicle speed spectrogram, subsection vehicle speed spectrograms, an average rotation speed spectrogram, subsection rotation speed spectrograms, an average torque spectrogram and subsection torque spectrograms under the conditions of different vehicle information and different road information; and determining the typical working condition corresponding to the vehicle information and the road information. The invention further discloses a system for acquiring the vehicle typical working condition.

Description

technical field [0001] The invention relates to the field of vehicle design, in particular to a method and system for realizing the acquisition of typical working conditions of vehicles. Background technique [0002] At present, the society is paying more and more attention to the issue of energy saving and emission reduction. Reducing vehicle emissions and improving vehicle fuel economy will make important contributions to improving environmental pollution and alleviating the energy crisis. In the actual use of vehicles, depending on various factors such as driving roads, loading goods, and driving habits, vehicles generally have their own typical characteristics. For example, under different driving conditions, vehicles can have typical characteristics such as speed, speed, and torque. . Obtaining the typical characteristics of the vehicle, that is, obtaining the typical working conditions of the vehicle, can truly describe the daily operating characteristics of a specifi...
