The invention relates to the field of data analysis, in particular to a vehicle running working condition identifying method and system. The vehicle running working condition identifying method comprises the steps that the running speed, roll angle speed, pitch angle speed and yaw angle speed of a vehicle are acquired; according to the running speed of the vehicle, an idling working condition fragment is obtained; according to the roll angle speed, pitch angle speed and yaw angle speed, the vertical acceleration of vehicle running is calculated; according to the change situation of the vertical acceleration direction, ramp working condition fragments are obtained, wherein the ramp working condition fragments include an uphill road section working condition fragment, a downhill road sectionworking condition fragment, a slow road section working condition fragment and a ramp turn working condition fragment; preset vehicle running working condition fragment sample sets are clustered to obtain a best clustering r
