The invention provides a position recognition system of a vehicle universal bus module and a recognition method of the position recognition system. The system comprises a power supply, a key switch ON gear, a vehicle meter and a plurality of universal bus modules which have the same structure. The vehicle meter is connected with the multiple universal bus modules through CAN buses. The universal bus modules comprise an arousing circuit, a module power supply circuit, a central processor, a CAN communication interface circuit and a plurality of output interface circuits. The invention further provides the recognition method of the position recognition system of the vehicle universal bus module. Through simple software judgment, address recognition functions of different universal bus modules can be achieved, the universality and the applicability of the universal bus modules are enhanced, application complexity and the manufacturing cost of the universal bus modules are lowered, spare part inventory is lowered, and accordingly the manufacturing cost and the maintaining cost of vehicle auxiliary parts are saved.
Description
technical field [0001] The invention relates to the technical field of automobile control, in particular to a position identification system and an identification method of an automobile general bus module. [0002] Background technique [0003] With the continuous development of electronic technology, the application of electronic control modules in different parts of the automobile body is more and more extensive, and its functions and types are also increasing. The usual design is to design hardware and software for each electronic control module separately, increasing A lot of repetitive work has been done, resulting in a serious waste of resources; a large number of spare parts, with various varieties and models, can easily lead to a backlog of funds and spare parts for manufacturers. Therefore, it is necessary to develop an electronic control module that can achieve different functional outputs in software through an integrated design with the same external hardware p...
