Embodiment Construction

[0062] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0063] public definition

[0064] 1) Definition of the opening direction of the brake pedal of an electric vehicle: when the brake pedal is fully lifted, the corresponding brake pedal opening is 0%, and when the brake pedal is depressed to the bottom, the corresponding brake pedal opening is 100%; the brake pedal opening is When entering the range of action of the mechanical brake, the greater the opening of the brake pedal, the greater the corresponding driving braking force.

[0065] 2) Definition of the opening direction of the accelerator pedal of an electric vehicle: when the accelerator pedal is fully lifted, the corresponding accelerator pedal opening is 0%, and when the accelerator pedal is in the bottom sta...

Abstract

The invention relates to a control method for an electric vehicle in a default torque setting mode. The control method comprises the following steps: pre-storing a torque and rotating speed optimization relation curve in the default torque setting mode in an electric vehicle controller; controlling the driving state of the electric vehicle according to the pre-stored torque and rotating speed optimization relation curve of the default set torque mode in the default set torque mode when the electric vehicle is driven in the complex road condition; and reducing the real-time torque given value of the driving motor of the electric vehicle along with the increase of the rotating speed value or increasing along with the reduction of the rotating speed value according to the optimization relation curve. According to the control method, the electric vehicle can have the driving control functions of safety, reliability, comfort in driving and simplified operation under the default set torque mode under the complex road condition.

Description

technical field [0001] The invention relates to the technical field of electric vehicle control, in particular to a control method for an electric vehicle in a default torque setting mode. Background technique [0002] Since the advent of automobiles, its application fields have become more and more extensive, and it has become an important symbol to measure the degree of development of a country. While automobiles bring us convenience and comfort, they are also accompanied by the massive consumption of oil resources and the increasing pollution of the global atmospheric environment. With the depletion of global oil resources and the increasing harm of atmospheric pollution and global temperature rise, governments and automobile companies generally recognize that energy saving and emission reduction are the development direction of future automobile technology, and electric vehicles are highly efficient, energy-saving and low-emission Or the environmental protection charact...
