Abstract

The invention relates to an address distribution method and device of vehicle body control modules, belongs to the technical field of address distribution, and aims at solving the problem that the versatility of vehicle body control modules is low. All of the N vehicle body control modules related to address distribution are connected via a CAN bus to form a distributive network, the Nth vehicle body control module serves as a master control module, and residual N-1 vehicle body control module serve as sub modules. The address distribution method comprises that sub modules are unlocked; and the master control module configures the address for the sub modules by configuring the address for the first sub module, and configuring the address for the ith sub module, and i is greater than 1 and lower than n. The address distribution method and device are applied to the vehicle body control modules of buses or trucks.

Description

technical field [0001] The invention belongs to the technical field of address allocation. Background technique [0002] With the popularization of CAN bus in automobiles, the application of body control modules in automobiles is increasing. to communicate. In buses or trucks, the body control modules mostly adopt a distributed structure, and each vehicle will be equipped with multiple modules, and because the functions of each module are basically the same, but the control logic relationship is quite different, so in the design process, it is generally used The hardware circuit of the body control module is designed to be the same, and different logic relationships are designed to perform different functions through the program software. This leads to the situation that the hardware of each module is the same, but the software is different, resulting in poor versatility of the body control module. Contents of the invention [0003] The object of the present invention is...
