WEIGHT ESTIMATION SYSTEM AND METHOD FOR AN ELECTRIC VEHICLE

A weight estimation system and method for an electric vehicle is provided. The weight estimation method includes: detecting the gear position mode of the electric vehicle, and detecting the slope information of the position of the electric vehicle when the gear position mode of the electric vehicle is detected as the parking gear position. When the gear position mode of the electric vehicle is detected as the drive gear position, the position change amount of the accelerator pedal of the electric vehicle at the nth second is detected. When the position change amount of the accelerator pedal exceeds half of the stroke of the accelerator pedal, and when the position change amount is maintained for k seconds and the range of the position change amount in k seconds is less than 10% of the position change amount at the nth second, the vehicle speed information of the electric vehicle at the (n+k)th second is collected. Based on the collected slope information, the position change amount, and the vehicle speed info
