Abstract

Disclosed is drive mode guide system for a vehicle provided with a plurality of drive modes. More specifically, a road information storage unit stores information related a road state. A real-time information storage unit receives and stores environmental information in real time. A vehicle information storage unit stores information related to the vehicle. A control unit then extracts a possible-traveling path and a drive mode and an outputs the possible-traveling path and a suggested drive mode received from the control unit based on the information stored in the road information storage unit, the real-time information storage unit, and the vehicle information storage unit.
