The invention discloses an early warning method for the vehicle driving intense degree. The early warning method comprises the steps of obtaining an engine rotating speed and torque data pair of a vehicle in the current driving process; judging whether the engine rotating speed and torque data pair is located in a first limit value area or a second limit value area, wherein the second limit valueregion is a enrichment region determined by taking an enrichment curve of the engine as a boundary, the first limit value area takes the first boundary curve and the enrichment curve as boundaries, and the data value on the first boundary curve is smaller than the data value on the enrichment curve; if the engine rotating speed and torque data pair is located in the first limit value area, sendingout early warning information of violent vehicle driving; if the engine rotating speed and torque data pair is located in the second limit value area, sending out violent vehicle driving alarm information; according to the early warning method, the adverse effect of artificial improper operation of a test driver on a pollutant emission test result in the driving process can be remarkably reduced.
本发明公开了一种车辆行驶激烈程度的预警方法,包括:获取车辆在当前行驶过程中的发动机转速‑扭矩数据对;判断发动机转速‑扭矩数据对是否位于第一限值区域或第二限值区域;其中,第二限值区域是以发动机的加浓曲线为边界确定的加浓区域;第一限值区域以第一边界曲线和加浓曲线为边界,第一边界曲线上的数据值小于加浓曲线上的数据值;若发动机转速‑扭矩数据对位于第一限值区域,发出车辆行驶激烈的预警信息;若发动机转速‑扭矩数据对位于第二限值区域,发出车辆行驶激烈的报警信息;上述预警方法能够显著减小试验司机在驾驶过程中由于人为的不正当操作对污染物排放试验结果产生的不利影响。
