Problems solved by technology

In the prior art, when the wake-up signal fails, the motor controller may directly execute the power-off operation because the wake-up signal cannot be detected. If the vehicle is in a normal driving state at this time, it will cause serious harm to driving safety and affect user experience.

Embodiment Construction

[0021] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0022] The motor controller wake-up system fault handling method and the motor controller according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0023] Various embodiments of the present invention aim at the existing motor controller wake-up mode. When the wake-up signal fails, the motor controller may directly perform power-off operation because the wake-up signal cannot be detected. If the vehicle is in a normal driving state at this time, it will To cau...

Abstract

The invention provides a motor controller arousal system fault handling method and a motor controller. The method comprises the steps that when the motor controller confirms that an arousal signal isabnormal, whether the current communication state with the whole vehicle controller is normal or not is judged; if not, a motor is controlled to stop torque outputting after warning information is output. In this way, fault handling of a motor controller arousal system is achieved when the arousal signal is abnormal, and the phenomenon that when the arousal signal is abnormal, serious damage is caused to the driving safety when power down operation is directly executed by the motor controller is avoided, the driving safety is improved, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of motor control, in particular to a motor controller wake-up system fault handling method and a motor controller. Background technique [0002] With the development of permanent magnet materials, power electronics technology, control theory, motor manufacturing and signal processing hardware, permanent magnet synchronous motors with advantages such as high efficiency, high output torque, high power density and good dynamic performance have been widely used. , the motor controller for permanent magnet synchronous motor has become a current research hotspot. [0003] In the prior art, after the vehicle is powered on, the vehicle controller "wakes up" the motor controller by sending a level signal or network wake-up, and the motor controller starts to work after receiving the wake-up signal sent by the vehicle controller (motor The controller is powered on), and the driving system is controlled acco...
