Problems solved by technology

[0004] Although the patent’s self-adaptive driving behavior scheme discloses that the driving state information of the vehicle can be collected, and the driving behavior of the driver is analyzed according to the driving state information of the vehicle, the driving behavior model of the driver is established, and then the driving behavior of the car is analyzed. However, the driving state data collected in this scheme cannot accurately reflect the real driving mode of the vehicle, and cannot reasonably save vehicle power resources

Abstract

The invention relates to the technical field of automobile control methods, in particular to a driving style judgment and recognition method. The method comprises the following steps: acquiring a vehicle speed signal and an accelerator pedal opening signal of a vehicle, starting to sample the accelerator opening signal of the vehicle when a sampling condition is met, and completing a period of sampling after accumulated sampling time reaches a set value; dividing the accelerator opening degree and the accelerator opening degree change rate of each sampling point of the vehicle in the accumulative sampling time through the calibrated style curve graph, and calculating the proportions of the sampling points in various driving styles in the style curve graph to determine a final driving style, wherein the style curve graph takes the accelerator opening degree as an abscissa and the accelerator opening degree change rate as an ordinate, and comprises a plurality of style calibration curves obtained through calibration. The judgment result can reflect the real driving mode of the vehicle, and vehicle power resources are reasonably saved.

Description

technical field [0001] The invention relates to the technical field of automobile control methods, in particular to a method for judging and recognizing driving styles. Background technique [0002] Nowadays, most automatic transmission models are equipped with a driving mode selection function. The driver can choose between "normal", "sport" and "economy" modes, but these require manual operation. However, the actual situation is that very few people will actively change the driving mode while driving. Most drivers are "one-D to the end", and the driving experience is relatively simple. In fact, the driver's pursuit of the driving experience is becoming more and more extreme: the ultimate driving freedom and the ultimate driving entertainment. [0003] There is a Chinese invention patent named "A Driving Behavior Adaptive System and Driving Behavior Adaptive Method" with the patent number "CN104590274A". This patent introduces a driving behavior adaptive method, which uses...
