Abstract

The invention discloses an automatic calibration method for a driving motor rack of a new energy automobile, which improves the rack calibration efficiency, enhances the calibration precision and reduces the labor intensity of a calibration engineer. According to the technical scheme, during matching of the rack of a driving motor of the new energy automobile, system resources of the rack are integrated; by automatic temperature returning control, automatic current setting and automatic data processing, motor control current can be automatically set, so that the precision of calibrating the motor rack is improved, and the motor rack calibration working efficiency is greatly improved. Particularly, the fluctuation of a magnetic chain of a rotor is reduced by controlling the temperature of the motor, a reading error is eliminated, and the precision of calibrating the motor control current is improved; therefore, an automatic procedure replaces frequent manual operation and visual inspection of the engineer, to realize continuous running and unattended operation, so that the working efficiency of motor rack calibration is greatly improved, and precious engineer resources are saved.

Description

technical field [0001] The present invention relates to the testing field of a new energy vehicle, in particular to the automatic calibration technology of the control current on the drive motor bench of the new energy vehicle. When the drive motor of the new energy vehicle matches the motor bench, the motor bench system resources are The motor controls the current to perform automatic calibration, thereby improving the calibration efficiency and calibration accuracy of the motor bench. Background technique [0002] In the field of new energy vehicle testing, the control current of the driving motor of the new energy vehicle needs to be calibrated on the bench. Currently, the calibration of the control current in the motor bench calibration is carried out manually. Manually calibrating the motor control current is very difficult for matching engineers. The requirements are high, the work intensity is high, the calibration period is long, and the calibration accuracy is not i...
