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.
本发明涉及汽车控制方法技术领域,具体地指一种驾驶风格判断识别方法。采集车辆的车速信号和油门踏板开度信号,当符合采样条件时开始对车辆的油门开度信号进行采样,累计采样时间达到设定值后完成一周期采样,通过标定的风格曲线图对车辆在累计采样时间内的各采样点的油门开度和油门开度变化率进行划分,统计风格曲线图中处于各类型驾驶风格采样点占比以确定最终驾驶风格;所述的风格曲线图是以油门开度为横坐标、油门开度变化率为纵坐包含多条通过标定获得的风格标定曲线的曲线图。本发明的判断结果能够反映车辆真实驾驶模式,合理节省车辆动力资源。
