ECU
Electronic Control Unit
Introduction
Introduction
The operation of the vehicle needs to be completed through the cooperation of many computer modules. There are many systems operating in the vehicle. Besides the modules in the system operate by themselves, they also need to cooperate with other system modules. ECU (Electronic Control Unit) is the controller of the system and also coordinates the information transmission among the system modules.

Electric Control Unit
The ECU, also called on-board computer, plays the core role in every automotive electronic system and controls lots of systems in the car. The internal components are composed of microprocessor (MCU), memory (ROM, RAM), I/O interface (I/O), analog-to-digital converter (A/D), shaping, driving and other large-scale integrated circuits.
Vehicle Control Core
ECU was first used in engine control. Later, with the improvement of vehicle electronic level, including the increase of vehicle active safety, automatic driving and other functions, ECU gradually covered the whole vehicle. It could store, calculate, analyze and process information, output execution commands and fault information, and complete a variety of control functions.
ECU Function
- Logic control function: ECU obtains input signal from the sensor or bus, outputs action through actuator after calculation, which is the most basic and original function of the ECU.
- Can Bus function: all ECUs exchange information. For example, the cluster needs the engine rotation information to display the current speed correctly.
- Diagnosis function: detect vehicle and find fault.
Operating Environment
Compared with general consumer electronics, automotive electronics must face challenges in the operating environment. The vehicle must adapt to the high temperature environment in the vehicle and the climatic environment of different countries, long-term movement and safety of the vehicle. In the design and manufacture, we must consider the high temperature in the vehicle environment, plus the anti-wet load, high temperature resistance, shock resistance and failure rate.
ECU Made By FIC
FIC ECU gateway collects the working signal of the automobile system through the sensor, and then transmits it back to the transmission line. The ECU judges, analyzes and calculates, and sends relevant instructions to the system to perform the corresponding work. In addition, each ECU has the function of message transmission to exchange information in the vehicle network system. In the event of a vehicle system failure, the ECU will record the fault information and send a reminder to the instrument panel, and sends analysis information to the actuator to maintain the vehicle operation.
Integration & Update
In addition, with the development of the automobile towards intelligence and network-connected, the embedded software will become more and more sophisticated and complex due to the fact that there are nearly hundred of ECUs operating in modern automobiles. OTA (Over-the-Air Technology) updates the software of the system through ECU, which makes the ECU integration function more important.
Because of its powerful function, small size and low cost, the Gateway has become an indispensable key component for vehicles. FIC plays a significant role to provide Automotive ECU design manufacturing services for car companies, like : Great Wall, Geely, Chana, VW and so on.
