Problems solved by technology

[0003] Although in the prior art, the self-adaptive control of the motor can be realized through the voltage closed loop, it is necessary to introduce calculation processes such as the square root operation, which makes the time required for the conversion of the working state of the motor longer, thereby reducing the control of the electric vehicle. efficiency

Abstract

The invention belongs to the technical field of control and provides a method and device for controlling running of an electric car. The method and device are used to process electric signals which control the electric car, so as to output corresponding direct axis current information and quadrature axis current information to a current ring. The method for controlling the running of the electric car is characterized in that if the electric signal which triggers speed changing of the electric car is detected, current vector information corresponding to the electric signal could be determined according to the electric signal; hysteresis ring tracking is conducted to the current vector information, so target value information of the current vector information can be obtained; slide mean information of the target value information of a current vector is obtained, and new current vector information is obtained according to the slide mean information; and the new current vector information is output to a current ring so as to control the running of the electric car. Hence, working ode conversion of a motor is simplified, and thus control efficiency of the electric car is increased.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a method and device for controlling the operation of an electric vehicle. Background technique [0002] With the promotion and popularization of new energy vehicles, more and more electric vehicles are sought after by consumers. Existing electric vehicles need to be driven by electric motors, that is, when the electric vehicle accelerates to a certain threshold, the electric motor works in the state of magnetic field weakening. The transition of the working state between the magnetic overspeed zones. [0003] Although in the prior art, the self-adaptive control of the motor can be realized through the voltage closed loop, it is necessary to introduce calculation processes such as the square root operation, which makes the time required for the conversion of the working state of the motor longer, thereby reducing the control of the electric vehicle. efficiency.
