Three-freedom electric automobile charging interface scanning positioning method

Abstract

The invention discloses a three-freedom electric automobile charging interface scanning positioning method. The method comprises a charge apparatus capable of moving in three mutually vertical directions and a controller, wherein the charge apparatus comprises a charge extending arm, and a stepping motor is arranged in each direction among an up-and-down direction, a left-and-right direction and a front-and-back direction; the charge extending arm is provided with a charge interface; the stepping motors control the movement of the charge extending arm in the corresponding directions; the controller an increasing and decreasing speed subprogram, a left-and-right moving subprogram, an up-and-down moving subprogram and a front-and-back moving subprogram; and through control of movement of the charge arm, space movement of a charge interface of an automatic charge apparatus is realized, the charge interface of the automatic charge apparatus automatically searches for a power receiving interface in an electric automobile through a search positioning method for charging, and the process is completely operated by the controller and the motors without manual intervention.

Description

technical field [0001] The invention relates to the field of automatic charging of automobiles, in particular to a method for scanning and positioning a charging interface of an electric automobile with three degrees of freedom. Background technique [0002] With the progress and development of society and technology, electric vehicles have become an important development trend in the future automotive industry and the entire power technology field. At present, my country's electric vehicle charging facilities are mainly non-vehicle charging devices, and charging stations have been built and used. And the charging pile, the use method is manual charging, and the degree of intelligence is low. The existing domestic electric vehicle automatic charging device has a device that provides charging and docking for electric vehicles based on vision. The image acquisition system is used to collect images in real time, and the computer image processing system is used to obtain the outl...
