Control method of pure electric sanitation vehicle bodywork motor based on can network

Abstract

The invention discloses a pure electric environmental sanitation vehicle drive motor control method based on the CAN network. A driver sends a drive motor working request to a finished vehicle controller through a touch screen; the finished vehicle controller judges whether the drive motor is allowed to work or not according to the current electric quantity of a high-voltage battery, the vehicle speed and the gear situation and feeds a permission order of the drive motor back to the touch screen; after receiving the working permission order of the drive motor of the finished vehicle controller, the touch screen sends a drive motor working enabling signal and a working revolving speed order from the driver to the drive motor controller; after receiving the enabling signal, the drive motor controller can control the revolving speed of the drive motor in a servo control mode through control of a revolving speed closed loop; meanwhile, a voice alarm is additionally arranged and records and reports the fault information of a finished vehicle and components in real time. The pure electric environmental sanitation vehicle drive motor control method has the advantages that the non-reliability and rudeness of traditional button type operation are greatly reduced; meanwhile, the problem of the poor real-time performance of the finished vehicle controller is solved.

Description

technical field [0001] The invention relates to a motor control method, in particular to a CAN network-based motor control method for a pure electric sanitation vehicle. Background technique [0002] With the increasing shortage of international crude oil resources and the increasingly stringent requirements on vehicle emissions caused by environmental pollution, new energy vehicles have gradually become a core research and development direction of major automobile manufacturers. In the "Twelfth Five-Year Plan", the development of new energy vehicles has become a key development project of the country, which has received great attention and strong support from the country. The national high-tech research and development plan (863 plan) also focuses on new energy vehicles and related projects, fully supporting the development of new energy vehicles and related industries. Under the guidance of various preferential policies and incentives, global electric vehicle demonstratio...
