Problems solved by technology

[0003] The disadvantage of this passive ID learning method is that the learning method is not flexible enough, and the slave board does not have the ability of self-learning. When there is no master board, it is impossible to perform unified commands and debugging on the slave board, thus limiting the development process.
And the hardware structure is relatively complex, in addition to the CAN line, it also needs a hard-wired connection

Abstract

The invention discloses a slave plate ID learning system and a method. The slave plate ID learning system comprises a master plate, multiple slave plates and a CAN bus. The master plate and the slave plates communicate via the CAN bus; in the multiple slave plates, a pin B of the former slave plate is connected with a pin A of a latter slave plate, a pin A of the first slave plate is grounded, and a pin B of the last slave plate is suspended. According to the slave plate ID learning system and the method, the slave plates can perform active ID learning, learning modes are flexible, and the master plate or an upper computer can control the slave plates; in addition, the system has a simple structure, only CAN bus communication is carried out between the master plate and the slave plates, hardwired connection is not needed, and realization is easy; and the number of slave plates is not limited, and expansion is facilitated.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a system and method for learning slave board IDs. Background technique [0002] The current automobile line control system has basically completed the automation, and the line control of each part is completed through control instructions between the various controllers on the vehicle. Among them, many parts are passed through the main controller, such as the main board or the upper machine, which controls the lower slave boards. For example, in a battery system, a battery pack consists of multiple battery modules. The entire battery pack has a master controller, and each battery module has a slave controller. The master controller The controller communicates with the slave controller through CAN, thus forming the communication between the main board and multiple slave boards. However, since the hardware structure and software code of the slave board are the same, in order t...
