A method and a system for constructing a driving coordinate system for use in the field of smart transport. The method for constructing a driving coordinate system comprises: determining the road boundary line on one side of the road on which a current vehicle is situated as a reference line for constructing a driving coordinate system (S 110); in a vehicle coordinate system, determining the reference line point having the smallest distance between the reference line and the current vehicle position as an origin point OF of the driving coordinate system (S 120); on the basis of the origin point OF, determining the road guiding line direction as the XF axis of the driving coordinate system and determining the direction relative to the road guiding line direction according to the left-hand rule as the YF axis of the driving coordinate system (S 130); and, on the basis of the origin point OF, the XF axis, and the YF axis, forming a corresponding driving coordinate system (S140). The driving coordinate system established thereby is particularly suited to curving road conditions and uses longitudinal arc length to represent the longitudinal distance to road targets, thus being capable of more realistically expressing the distance between roads targets and the current car compared to the straight line distances in vehicle coordinate systems.
