Connection system of vehicle electric appliance

Abstract

The present invention relates to a connecting system of electrical apparatuses of vehicle, and belongs to the technological field of electronic control of the vehicle. The connecting system comprises a backbone net wire, a local net wire which is used for connecting the electrical apparatuses of the vehicle and the backbone net wire, a power net wire which is used for providing power for the electrical apparatuses of the vehicle, a central coordinator which is used for coordinating and controlling the electrical apparatuses of the vehicle, and a central microprocessor which is used for displaying the status information and the failure information of the electrical apparatuses of the vehicle towards the vehicle driver. Compared with the connecting system of electrical apparatuses of the vehicle in the prior art, the connecting system greatly improves the degree of informationization of modern vehicles, and improves the capacity of information sharing and coordinated control. More importantly, the structure simplifies the wiring harness of the vehicle and reduces the production costs.

Description

technical field [0001] The invention relates to a connection system for automobile electric appliances, which belongs to the technical field of automobile electronic control. Background technique [0002] With the continuous development of automotive electronic technology, the number and types of electronic control devices on the car are increasing, and the electrical system of the car is becoming more and more complex. [0003] More and more information is exchanged between automotive electrical appliances, and there are more and more mechanisms that need to coordinate work, and the system requirements are becoming more and more reliable. At the same time, the cost of production and manufacturing is required to be lower and lower. Therefore, the design of modern automotive electrical systems is facing great challenges. As a whole, the car needs the coordination of the overall functions, but with the increase of electrical appliances, the coordination and working relationsh...

AI Technical Summary

Problems solved by technology

[0004] The current automotive electrical system adopts the method of vehicle network, such as the use of instrument bus system, modular body control system, etc., and also uses the controller local interconnection network (hereinafter referred to as CAN bus) bus or automobile local area Hereinafter referred to as the LIN bus) bus technology to simplify the design of the automotive electrical system. Information processing, etc. are relatively complicated, and the relationship between the backbone network and the local area network is not clear; 2. There is no power network in the strict sense, that is, the power supply of the vehicle has not been designed at the system level, so that the wiring harness of the car has not been reduced.
