Abstract

The invention discloses a variable information configuration method and device. The method comprises the steps of acquiring a variable list wherein the variable list comprises a plurality of variablesand the length of each variable; splitting each variable based on the length of each variable to obtain a plurality of variables with target byte lengths; and packaging the plurality of variables with the target byte length according to a preset rule, and transmitting the packaged message in a CAN bus based on an XCP protocol or a CCP protocol. The problem of low CAN message data transmission utilization rate based on an XCP protocol or a CCP protocol in related technologies is solved.

Description

technical field [0001] The present application relates to the technical field of information processing, and in particular, to a method and device for configuring variable information. Background technique [0002] At present, the main modes of data collection based on the XCP / CCP protocol are introduced as follows (taking INCA as an example). The object of collection is the ECU (taking EDC17 as an example). The number of CCP message frames sent by the ECU has an upper limit. 10. [0003] Assume that the list of variable information that needs to be collected is as follows: [0004] Table 1 [0005] variable name variable address variable length Acquisition cycle VAR1 ADDR1 4 10ms VAR2 ADDR2 4 10ms VAR3 ADDR3 4 10ms VAR4 ADDR4 4 10ms VAR5 ADDR5 4 10ms VAR6 ADDR6 4 10ms VAR7 ADDR7 4 10ms VAR8 ADDR8 4 10ms VAR9 ADDR9 4 10ms VAR10 ADDR10 4 10ms VAR11 ADDR1...
