Abstract

The invention provides a method and a system of controlling the working mode of an electric vehicle, and the electric vehicle having the same. The method comprises the steps of obtaining target power of a motor at multiple speeds and multiple accelerator pedal openings through adjusting the speed and the accelerator pedal opening of the electric vehicle, and determining a control curve graph of the motor according to the target power of the motor at the multiple speeds and multiple accelerator pedal openings, wherein the control curve graph includes multiple control curves; and detecting the speed and the accelerator pedal opening of the electric vehicle, determining a working point of the electric vehicle in the control curve graph according to the speed and the accelerator pedal opening of the electric vehicle, and adjusting the target power of the motor according to the power of a control curve corresponding to the working point, to control the running of the electric vehicle. According to the method disclosed by the embodiment of the invention, the target power of the motor is adjusted through determining the control curve graph of the motor and determining the position of the working point of the electric vehicle, the manual operation is avoided, the efficiency and the load rate of the motor are improved, and the power consumption of the vehicle is reduced.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a control method and system for the working mode of the electric vehicle and an electric vehicle having the same. Background technique [0002] In order to reduce the power consumption of electric vehicles, electric vehicles such as Mercedes-Benz and Mitsubishi have set working mode selection buttons on the dashboard. The driver selects the working mode according to the actual road conditions and personal wishes. The working mode determines the target power of the motor. Generally, the working mode can be roughly divided into power mode and economic mode. When the driver selects the power mode, the target power of the motor is large and the power performance is good; when the economic mode is activated, the output power of the motor is small and the load rate is high. Controls according to the selected mode and several efficiency graphs set in the motor controller. When the ac...
