Abstract

The invention provides an electromobile motor control method and device and an electromobile. The method comprises the steps that a current operation condition of the electromobile is acquired; according to the current operation condition, target filtering parameters are determined; the target filtering parameters are utilized to carry out filtering treatment on a collected current signal and / or amotor rotating change angle; according to the treated current signal and / or the motor rotating change angle, operation conditions of the electromobile motor are controlled. Therefore, reliable filtering is carried out on the current signal and the motor rotating change angle under various operation conditions, the accurate basis is provided for motor control, the situations such as shaking, burning of drive devices and the like which occur on the electromobile under the current operation condition are effectively avoided, drive safety is improved, the service life of the electromobile is prolonged, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of new energy technology, in particular to an electric vehicle motor control method and device, and the electric vehicle. Background technique [0002] With the development of the economy and the further aggravation of environmental and energy issues, people's awareness of environmental protection has gradually increased. Electric vehicles are driven by electricity and have the advantage of zero emission, so they are gradually favored by people. [0003] As the main component of the electric vehicle power system, the motor has an extremely important impact on the reliability and safety of the electric vehicle. At present, the motor control method in electric vehicles is as follows: firstly, after filtering the current signal and resolver signal of the motor collected during the driving of the electric vehicle, and then controlling the motor speed, torque, etc. according to the filtered current signal and re...
