Patent ID: 8498764

Claim:
An electric vehicle using a motor, the electric vehicle comprising: a battery configured to provide electric energy to the motor; a remaining energy-amount detector configured to detect a remaining energy-amount of the battery; a manipulation unit configured to receive target information from a user, wherein the target information comprises at least one of i) a target driving distance defined as a distance in which a user of the electric vehicle wants to drive the electric vehicle and ii) a destination information which is used to calculate a destination distance between the current location of the user or electric vehicle and the destination; a guide information generator configured to generate driving guide information based at least in part on the remaining energy-amount of the battery and the target information; and a display unit configured to display the driving guide information, wherein the electric vehicle is configured to operate in an operation mode, and wherein the operation mode is a first mode operated based on the electric energy of the battery or a second mode operated based on the electric energy of the battery and a torque applied by the user; and a distance calculator configured to calculate a first driving distance in which the electric vehicle operates in the first mode and a second driving distance in which the electric vehicle operates in the second mode, based on the remaining energy-amount of the battery, wherein, when the first driving distance is greater than the destination distance or the target driving distance, the guide information generator is configured to generate the first driving distance as the driving guide information, and wherein, when the second driving distance is less than the destination distance or the target driving distance, the guide information generator is configured to generate the second driving distance as the driving guide information.
