Problems solved by technology

During the driving process of an electric vehicle, it is often impossible to drive to the destination or the nearest charging station due to low battery power, and sometimes the battery power is exhausted and the electric vehicle stops halfway.
If these situations happen many times, it will make the driver feel uneasy, and even dare not choose electric vehicles as a means of transportation.

Abstract

The invention relates to an electric car and a control device and method thereof. The control method comprises the steps that a destination is input; the travelling path and path distance from the current position to the destination are planned, the left electric quantity of a battery pack is detected, and the driving mileage maintained by the left electric quantity of the battery pack is estimated in real time; the driving mileage maintained by the left electric quantity and the driving path distance from the current position to the destination are compared, and if the driving mileage maintained by the left electric quantity is larger than the driving path distance from the current position to the destination, the electric car is driven in a normal mode; if the driving mileage maintainedby the left electric quantity is smaller than the driving path distance from the current position to the destination, the electric car is driven in an electricity-saving mode; and according to the electricity-saving mode, at least one of the motor output power, the driving current, the driving voltage, the highest speed and the largest acceleration is limited.

Description

technical field [0001] The invention relates to an electric vehicle and its control method and device. Background technique [0002] Electric vehicles are more and more widely used because of their low pollution and low noise. The mileage of existing electric vehicles is mainly determined by the power of the battery. During the driving process of the electric vehicle, it is often impossible to drive to the destination or the nearest charging station due to low battery power, and sometimes the battery power is exhausted and the electric vehicle stops halfway. If these situations occur many times, the driver will feel uneasy, and even dare not choose electric vehicles as a means of transportation. Contents of the invention [0003] The present invention aims to solve the problems of the prior art. [0004] Therefore, according to one aspect of the present invention, a method for controlling an electric vehicle is provided, including: [0005] Enter the destination; [0...
