1. On the one hand, there is a shortage of energy, environmental protection and safety issues, which promote the continuous improvement of the requirements of automobile fuel consumption regulations, emission regulations and safety regulations.

2. On the other hand, the level of electronic technology is constantly improving.

With the application of electronic technology, computer technology and information technology, automotive electronic control technology has developed rapidly, especially in the control accuracy, control range, intelligence and networking and other aspects have made great breakthroughs. Automotive electronic control technology has become an important symbol to measure the development level of modern automobiles.

Trends. With the development of integrated control technology, computer technology and network technology, automotive electronics technology has obviously developed in three main directions: integration, intelligence and networking.

In recent years, the maturity of embedded systems, LAN control and data bus technologies has made the integration of automotive electronic control systems an inevitable trend in the development of automotive technology. Integrate the engine management system and automatic transmission control system into the integrated control of the power transmission system; Brake control is integrated with anti-lock braking control, traction control system and drive anti-skid control system.

Through the first chassis controller, the brake, suspension, steering, power transmission and other control systems are connected through the bus, and the controller coordinates the subsystems through complex control calculations, controls the vehicle driving performance to the best level, and forms an integrated chassis control system.

The development of intelligent sensing technology and computer technology has accelerated the intelligent process of automobiles. Technical issues related to automotive intelligence have been highly valued by automobile manufacturers. The idea of an autopilot is one of its main technologies, which will be realized by electronic technology.

The development of intelligent transportation systems (ITS) will be combined with multiple interdisciplinary disciplines such as electronics and satellite positioning.

Based on the target information provided by the driver, it can provide the driver with the shortest distance and the best route to avoid the relatively dense concentration of vehicles. It is equipped with an electronic map that shows the road ahead and uses satellite navigation. Obtain various conditions such as weather, traffic flow, traffic accidents, and traffic jams along the route from GPS, and automatically filter out the best driving routes.

NetworkingWith the increasing application of electronic control devices in automobiles, data communication between on-board electronic devices is becoming more and more important. It is necessary to construct an automotive on-board electronic network system based on a distributed control system.

Fast exchange of large amounts of data, high reliability and low cost are the requirements for automotive electronic network systems. In this system, each subprocessor operates independently, controlling and improving the performance of one aspect of the vehicle, while providing data services when other processors need it. The main processor collects and sorts out the data of each subprocessor and generates a vehicle condition display.

There are more and more cars, and more and more innovation, so the electronic control technology is becoming more and more developed.

Hello! From the perspective of fuel system, the development trend of automotive electrical equipment has been developed from carburetor type to electronic injection system, which is completely controlled by computer, and has the characteristics of precision, economy and strong power. In addition, in braking, it has been completely controlled by humans, transformed into electronic intervention, the most common of which is the ABS system, etc., and from the perspective of vehicle safety, the active safety system continues to develop, from the ordinary cruise system to the adaptive cruise system; Cooperate with braking system, ABS to increase driving force control and other safety systems; There are also lane departure warning systems, automatic braking systems, fatigue driving reminder systems, driving record systems, etc., as well as power windows and anti-pinch systems, electric suction doors, panoramic sunroofs, electric or induction opening of the trunk lid, automatic parking, engine start-stop system, panoramic cameras, etc.; In short, the future development direction of automotive electrical equipment is to develop in the direction of full intelligence.

Hope it helps!

With the advancement of the new four modernizations of automobiles, the electronic and electrical architecture of automobiles has entered a stage of comprehensive innovation. The electronic and electrical architecture of intelligent vehicles will move from distributed to centralized: vertical integration will replace distributed collaboration, and the demand for software-defined vehicles will promote the magnificent transformation of vehicles from mechanization to electronics.

This article will focus on interpreting the composition and characteristics of the future automotive E/E architecture, analyze the key factors that will reshape the future architecture, and summarize the future trends of the E/E architecture.

1. The background and driving force of the innovation of electronic and electrical architecture.

With the advancement of the new four modernizations of automobiles, automotive technology is achieving comprehensive innovation in terms of control mode, energy form, use scenarios and commercial applications, and the electronic and electrical architecture of intelligent vehicles is moving from distributed to centralized. In order to improve the intelligence, comfort and safety of the vehicle, more electronic modules such as sensors, controllers, and actuators are introduced into the car, which also makes the network architecture in the car more and more complex, the requirements for communication connection technology are getting higher and higher, and the original electronic and electrical architecture is also saturated, which can no longer meet the requirements of the development of the new four modernizations.

For the future automotive electronic architecture, vertical convergence will replace distributed collaboration as a trend. At the same time, the need for software-defined and the need for a mechanized to electronic transformation of the vehicle requires a change in the electrical and electronic architecture of the vehicle: to increase efficiency and reduce complexity—both in terms of hardware manufacturing complexity and software development.

The introduction of new in-vehicle high-speed network technology and 5G wireless technology has made this convergence a partial reality. If the network bandwidth is wide enough and the latency is low enough, this trend will be more obvious: computing power is concentrated in the first and the cloud, and the evolution of automotive electronic and electrical architecture is also going in this direction.

Under the architecture of the domain controller, each functional component becomes an independent domain, and under each domain there is a corresponding set of control functions. Domains can be safely isolated from each other, and communication and interoperability can also be carried out according to requirements, forming a computer LAN similar to the Ethernet bus, which has become a loosely coupled architecture.

Global energy shortage, environmental protection, and traffic safety issues have promoted the continuous improvement of the requirements of automobile fuel consumption regulations, emission regulations and safety regulations, and promoted the rapid development of automotive electronic control technology.

The rapid development of automotive electronic control technology is mainly due to the country's energy-saving and emission reduction policies and a driving force for the rapid development of technology.
