Abstract

The invention discloses a method for obtaining a physical quantity corresponding to CAN data. The method comprises that a first CAN data frame before the specific physical quantity is obtained and a second CAN data frame after the specific physical quantity is obtained are obtained; corresponding positions of all the same CAN ID in the first and second CAN data frames are compared; when a specific corresponding position of the CAN ID of the first CAN data frame is different from that of the same CAN ID of the second CAN data frame, the CAN ID and a candidate position of the specific corresponding position are recorded; and the recorded CAN ID and candidate position of the specific corresponding position are determined to be the physical quantity corresponding to specific CAN data. Correspondingly, the invention discloses a device for obtaining the physical quantity corresponding to the CAN data, a CAN data processing system and electronic equipment. According to technical schemes of the invention, the analysis efficiency of the physical quantity corresponding to the CAN data is improved.

Description

Technical field [0001] The present invention relates to the technical field of automotive electronic data processing, in particular to a method, device and equipment for acquiring physical quantities corresponding to CAN data. Background technique [0002] The Controller Area Network CAN (Controller Area Network) bus can realize real-time and reliable serial data communication between the nodes of the distributed control system, and it has been widely used in the field of automotive electronics. At present, many automotive electronic products can process and calculate CAN data on the car's CAN bus, and obtain physical information such as the current car's speed, steering, and braking. Existing CAN data obtained through CAN analysis software can only manually analyze the change law of CAN data and then manually determine the physical quantity corresponding to the CAN data. The actual workload and work difficulty are relatively large, resulting in a relatively efficient analysis of...
