The invention is suitable for the technical field of computer application, and provides a driving style identification method and device, and the method comprises the steps: obtaining the driving dataof a to-be-tested driver in a preset time period; constructing time series data corresponding to the driving data according to the generation time and the data type of the driving data; extracting data features corresponding to each block in the time series data according to a preset nested time window method; and combining the data features corresponding to all the blocks to obtain the data features of the driving data; constructing a corresponding pixel lattice diagram of the driver to be tested during driving in a preset time period according to the data characteristics; and analyzing thepixel lattice diagram to obtain the driving style of the driver to be tested. The driving data based on the time sequence is subjected to data feature extraction of the large and small windows according to the nested time window method, and the pixel dot matrix graph is constructed based on the data features of the time sequence, so that the style of the driver to be tested is visually and clearlyrecognized according to the pixel dot matrix graph, and the accuracy and intuition of driver driving style recognition are improved.
Description
technical field [0001] The present application belongs to the field of computer application technology, and in particular relates to a driving style recognition method and device. Background technique [0002] Driving style is defined as personal driving habits gradually formed by accumulated driving experience. Driving style has an important influence on driving safety and energy economy. Drivers with different driving styles will affect road traffic safety to varying degrees, and have a greater impact on the energy consumption of the vehicle itself. In addition, prior knowledge about driving style is also of great help in designing driver assistance systems, which can better fit the driver and improve the performance of driver assistance systems. [0003] In the prior art, various classification methods are used to classify the driver's driving style to determine the type corresponding to the driver's driving style. However, the driver's driving behavior is affected by m...
