The invention provides a controller SD card information reading method and device based on CAN bus communication. The method comprises the steps: receiving an SD card information reading instruction; resolving the SD card information reading instruction; according to the SD card information reading instruction, obtaining data in an SD card; and sending the obtained SD card data to an information receiving device, wherein the controller supports a CAN bus communication way. According to the embodiment of the invention, the SD card information reading instruction is received and resolved, the data in the SD card is obtained according to the SD card information reading instruction, and the obtained SD card data is sent to the information receiving device; in the process of obtaining the controller SD card data, disassembly is not needed, the defects of SD card inconvenient disassembly brought by packaging and installation positions of a conventional controller are avoided, an auto part self CAN network is used, and the data of the controller SD card is convenient and safe to read.
Description
technical field [0001] The invention relates to the technical field of auto parts development, in particular to a method and device for reading SD card information of a controller based on CAN bus communication. Background technique [0002] With the continuous development of the development technology of auto parts, the testing of auto parts is also more stringent. For the real-time operation data and system faults of the controller (Electronic Control Unit, ECU) itself and even the whole system with the controller as the core analysis becomes particularly important. [0003] Secure Digital Memory Card (Secure Digital Memory Card, SD) is a new generation of memory device based on semiconductor flash memory. The SD memory card is as big as a postage stamp and weighs only 2 grams, but it has high memory capacity and fast data. Transmission rate, great mobile flexibility and good security; it is a multi-functional memory card with many characteristics such as large capacity, ...
