Title: ELECTRIC VEHICLE, AND CONTROL DEVICE AND METHOD THEREFOR
Abstract:
The present application relates to an electric vehicle, a control method and a device therefor. The control method comprises inputting a destination; programming a driving route and distance from the current position to the destination, detecting a battery module's battery level, and estimating the electric vehicle's endurance mileage in real-time on the basis of the battery module's battery level; and comparing the endurance mileage on the basis of the battery module's battery level with the route distance from the current position to the destination, if the former is greater than the latter, driving the electric vehicle in a normal mode; if the former is less than the latter, driving the electric vehicle in a power saving mode; wherein the power saving mode comprises limiting at least one of the output power, the driving electric current, the driving voltage, the maximum speed and the maximum acceleration of an electric motor. Thus, when the battery level of the battery module is low, the endurance mileage of the electric vehicle is increased. This ensures, as far as possible, that the electric vehicle reaches the destination and effectively prevents the electric motor from stopping due to battery power exhaustion when the electric vehicle is driven.
