Patent ID: 8924146

Claim:
A drive mode guide system for a vehicle provided with a plurality of drive modes, comprising: an input unit configured to receive data input by the user, wherein the data input by the user is destination data; a road information storage unit configured to store information related to a road state; a real-time information storage unit configured to receive and store environmental information in real time; a vehicle information storage unit configured to store information related to the vehicle; a control unit configured to extract a possible-traveling path and a drive mode for the vehicle based on the real-time information, vehicle information and road state information; and an output unit configured to output the possible-traveling path and the drive mode received from the control unit, wherein the control unit is configured to: extract the possible-traveling path for the vehicle from the destination data received from the input unit, extract an expected consumed energy flow for the possible-traveling path from information received from the road information storage unit, the real-time information storage unit, and the vehicle information storage unit, and extract a drive mode suitable for the expected consumed energy flow for the possible-traveling path and the traveling information from the plurality of drive modes, wherein the expected consumed energy flow is extracted by configuring the control unit to: calculate a dynamic load state applied to the vehicle during virtual travel through the possible-traveling path from information received from the road information storage unit, the real-time information storage unit, and the vehicle information storage unit; calculate a fluid resistance state applied to the vehicle during the virtual travel through the possible-traveling path from information received from the real-time information storage unit and the vehicle information storage unit; calculate a fuel consumption rage of the vehicle during virtual travel through the possible-traveling path from information on the calculated dynamic load state and fluid resistance state of the vehicle; and calculate a heat load state of the vehicle from information received from the vehicle information storage unit based on the expected energy flow in the vehicle.
