Control method of motor controller integrated assembly for electric vehicle, and electric vehicle

Abstract

The invention discloses a control method of a motor controller integrated assembly for an electric vehicle, and the electric vehicle. A controller and a stator assembly are installed into a whole, wherein the controller is electrically connected with a power supply positioned outside a motor shell, so that the power supply input of the controller is realized; the controller is in two-way communication connection with a central control device located outside the motor shell, the central control device sends a central control instruction to the controller, and the controller sends a wheel movement signal of the electric vehicle to the central control device to serve as an anti-theft input signal; and the controller is electrically connected with a winding phase line of the stator assembly. On the basis that the controller and the motor are integrated, the control process is simple, stable and reliable, the wiring harness structure of the controller can be simplified to a great extent, excessive burden cannot be caused to the installation layout and heat dissipation in the motor, and meanwhile the conventional driving performance of the electric vehicle cannot be affected.

Description

technical field [0001] The invention belongs to the field of drive control of electric vehicles, and in particular relates to a control method of a motor controller integrated assembly for an electric vehicle, and also relates to an electric vehicle to which the control method is applied. Background technique [0002] With the technical development of motor drive control technology, subject to the strict compact installation requirements, in the field of household appliances and power tools, the motor and controller have basically realized integrated installation, and because of the field of household appliances and power tools, the motor's The working power is small, so after the motor and the controller are integrated, the problem of heat dissipation is small, which has become a key factor for the integration of the motor and the controller in these fields. [0003] Specifically for the field of electric vehicles, since the brushless permanent magnet synchronous motor has ...

Problems solved by technology

However, the oil-proof breather valve and vent pipe used in this solution are exposed to the outside, which not only has hidden dangers of liquid leakage, but also causes hidden dangers to the service life of wire components. Therefore, the heat dissipation scheme adopted has hidden dangers in quality. After the electric vehicle motor is integrated with its controller, there will still be a risk of electromagnetic interference. At the same time, other functional control modules of electric vehicles, such as anti-theft modules, vibration modules and DCDC power modules, how to solve the problem of integrated control layout and other issues
