Motor controller, and reset processing method and device thereof

Abstract

The invention discloses a reset processing method of a motor controller. The reset processing method comprises the following steps of storing working condition data of the motor controller to a target memory space; detecting whether the motor controller is reset or not; when the motor controller is reset, judging whether the working condition data exists in the target memory space or not; judging the reset type of the motor controller according to the existing situation of the working condition data; when the reset type of the motor controller belongs to non-power-on reset, judging whether the working condition data is valid or not; and when the working condition data is valid, controlling the motor controller according to the working condition data. According to the reset processing method disclosed by the invention, the working condition data of the motor controller before generating the non-power-on reset can be obtained conveniently and accurately, the operation is simple, the data obtaining efficiency is high, and besides, the reset type of the motor controller can also be judged. The invention also discloses a reset processing device of the motor controller, and a motor controller which comprises the reset processing device of the motor controller.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a reset processing method of a motor controller, a reset processing device of a motor controller and a motor controller. Background technique [0002] In the related technology, after the working condition data of the motor controller (hereinafter referred to as the motor) is transmitted to the host computer through CAN (ControllerAreaNetwork, controller area network) communication, the host computer starts the monitoring function and records the working condition data within a period , so that after a non-power-on reset of the motor, the user can obtain the working condition data before the motor reset by viewing the working condition data recorded by the host computer. Among them, such as figure 1 As shown, the data transmission relationship between CAN communication, motor controller and host computer is described. [0003] The disadvantages of obtaining the working conditi...

AI Technical Summary

Problems solved by technology

[0003] The disadvantages of obtaining the working condition data of the motor before power-on reset through CAN communication and the host computer in the above-mentioned related technologies are: low operating efficiency, need to rely on the monitoring data of the host computer, high functional requirements for the host computer, and the host computer The range of working condition data that can be recorded by the machine is narrow, and the monitoring period is too long, which leads to the slow speed of obtaining working condition data. In addition, some real-time working condition data cannot be monitored, and the accuracy of working condition data is insufficient.
