Electric vehicle CAN bus node universal controller

Abstract

The invention discloses an electric vehicle CAN bus node universal controller, which is composed of an input side end cover, an output side end cover, an input side CAN bus socket, an output side CAN bus socket, a PCB and an embedded ARM chip, and is characterized in that: the center of the input side end cover is provided with the input side CAN bus socket, the center of the output side end cover is provided with the output side CAN bus socket, the PCB is installed inside the input side end cover, 12 two-core vehicle special sockets are arranged on the output side end cover, and vehicle-mounted electrical appliances can be controlled directly. The electric vehicle CAN bus node universal controller provided by the invention is a CAN bus node control device combined with vehicle wire harnesses, changes the past practice of dividing CAN bus modules into a master control module and various functional modules, directly replaces a relay box through a series mode of the input side CAN bus socket and the output side CAN bus socket, reduces back and forth wiring, and has very extensive application.

Description

technical field [0001] The invention relates to a general controller for CAN bus nodes of an electric vehicle, which is mainly used to replace the traditional wiring harness of the electric vehicle, and realize the centralized and distributed nearby control of the vehicle-mounted local area network and the vehicle-mounted electrical appliances. Background technique [0002] The traditional automotive wiring harness is a very troublesome thing from production to installation. First of all, most of the work in the production process of automobile wiring harnesses needs to be done by hand, and cannot be completely replaced by machines; More than 20 times of that, the reliability of the connection between numerous wiring harnesses and on-board electrical equipment is itself a problem, which not only causes difficulties in maintenance, but more importantly, becomes the biggest obstacle to further lightweighting and electronicization of automobiles. For this reason, from the en...

AI Technical Summary

Problems solved by technology

First of all, most of the work in the production process of automotive wiring harnesses needs to be done by hand, and cannot be completely replaced by machines; second, at present, there will be more than 1,000 signal lines connecting all electronic devices and equipment on a high-end car, which is equivalent to the wiring harness used in the past. More than 20 times of that, the reliability of the connection between numerous wiring harnesses and on-board electrical equipment is itself a problem, not only causing difficulties in maintenance, but more importantly, becoming the biggest obstacle to further lightweighting and electronicization of automobiles
