An adaptive driving behavior adjusting method for an electric vehicle, comprising the steps of: estimating an endurance mileage of the electric vehicle; acquiring information of a location of the nearest charging pile or a destination; acquiring information of a lane in which the electric vehicle is currently traveling, wherein the information of the lane includes an average vehicle speed, the terrain, and a speed limit; and causing the electric vehicle to selectively entering a forced adaptive driving mode or an optional adaptive driving mode, based on the endurance mileage of the electric vehicle, the information of the location of the charging pile or the destination and the information of the lane, wherein when the distance between the electric vehicle and the charging pile or the destination is greater than the endurance mileage but the difference therebetween is less than an upper threshold distance, or when the distance between the electric vehicle and the charging pile or the destination is less than the endurance mileage but the difference therebetween reaches a lower threshold distance, the electric vehicle enters the forced adaptive driving mode; wherein in the adaptive driving modes, the vehicle travels at the most economical speed to maximize the endurance mileage, wherein when the state of charge of the electric vehicle is less than threshold state of charge and the average vehicle speed is greater than a threshold vehicle speed, the electric vehicle enters the optional adaptive driving mode, wherein when the electric vehicle enters the optional adaptive driving mode, the electric vehicle prompts the driver to confirm whether to enter the optional adaptive driving mode in order to increase the endurance mileage. estimating an endurance mileage of the electric vehicle; acquiring information of a location of the nearest charging pile or a destination; acquiring information of a lane in which the electric vehicle is currently traveling, wherein the information of the lane includes an average vehicle speed, the terrain, and a speed limit; and causing the electric vehicle to selectively entering a forced adaptive driving mode or an optional adaptive driving mode, based on the endurance mileage of the electric vehicle, the information of the location of the charging pile or the destination and the information of the lane, wherein when the distance between the electric vehicle and the charging pile or the destination is greater than the endurance mileage but the difference therebetween is less than an upper threshold distance, or when the distance between the electric vehicle and the charging pile or the destination is less than the endurance mileage but the difference therebetween reaches a lower threshold distance, the electric vehicle enters the forced adaptive driving mode; wherein in the adaptive driving modes, the vehicle travels at the most economical speed to maximize the endurance mileage, wherein when the state of charge of the electric vehicle is less than threshold state of charge and the average vehicle speed is greater than a threshold vehicle speed, the electric vehicle enters the optional adaptive driving mode, wherein when the electric vehicle enters the optional adaptive driving mode, the electric vehicle prompts the driver to confirm whether to enter the optional adaptive driving mode in order to increase the endurance mileage.
