General electronic and electrical architecture for new energy automobiles

Abstract

The invention discloses a new energy automobile general electronic and electrical architecture, which is characterized by comprising three layers and three domains, the three layers comprise a centralcontrol layer, a regional function layer and a terminal interaction layer, and the three domains comprise an intelligent driving domain, an automobile body entertainment domain and a power domain. According to the invention, the complexity of the electronic and electrical architecture of the whole vehicle is greatly reduced, and the number of electronic and electrical components is also greatly reduced; the number of special controllers for the whole vehicle is greatly reduced, so that the development cost and the procurement cost are greatly reduced; each universal controller of the regionalfunction layer is close to a sensor actuator, so that the use amount of whole vehicle wiring harnesses is greatly saved, and a large amount of cost is saved; and the weight of the whole vehicle and the energy consumption of the whole vehicle can be reduced while the wiring harness consumption is reduced.

Description

technical field [0001] The invention relates to the field of electrical and electronic architecture, in particular to a general electrical and electronic architecture for new energy vehicles. Background technique [0002] At present, the electronic and electrical architecture of new energy vehicles basically follows the distributed control architecture of traditional fuel vehicles. Each key component or area of ​​the vehicle is controlled by a large number of dedicated controllers, such as the engine. Controlled by the engine controller (ECU), the motor It is controlled by the motor controller (MCU), and the body is controlled by the body controller (BCM). These dedicated controllers communicate with each other through several buses, and the network manager forwards signals or communication messages between the buses. [0003] The current distributed architecture has the following drawbacks: [0004] 1. The entire electronic and electrical architecture is very complex, and...

AI Technical Summary

Problems solved by technology

[0004] 1. The entire electronic and electrical architecture is very complex, and the management and coordination of various components are very difficult;

[0005] 2. The degree of specialization of each controller is high, the unit price is high, the development cost is high, and the development cycle is long;

[0006] 3. Unable to make full use of dedicated controller hardware resources, resulting in waste of resources;

[0007] 4. The distance between each controller and some sensors or actuators is long, a large number of wiring harnesses increases the cost of wiring harnesses and connectors, and at the same time greatly increases the weight of the vehicle
