Car terminology driving computer

The driving computer is actually the driving computer which is the ECU, which is generally used on the EFI vehicle. Generally used to control the fuel injection rate, the mixture ratio and so on. In simple terms, the ECU consists of a microcomputer and peripheral circuits. A microcomputer is a unit that integrates a microprocessor (CPU), memory, and an input/output interface on a single chip. The main part of the ECU is the microcomputer, and the core part is the CPU. The ECU converts the input signal into a digital form, performs comparison processing based on the stored reference data, and calculates the output value. The output signal is then amplified by the power to control several servo components such as relays and switches. Therefore, the ECU is actually an "Electronic Control Unit", which consists of three parts: the input circuit, the microcomputer, and the output circuit. The input circuit accepts signals from sensors and other devices, filters and amplifies the signal, and then converts it to a certain volt input level. The signal sent from the sensor to the ECU input circuit has both analog and digital signals. The analog/digital converter in the input circuit can convert the analog signal into a digital signal and pass it to the microcomputer. The microcomputer performs arithmetic processing on the signal that has been preprocessed, and sends the processed data to the output circuit. The output circuit amplifies the power of the digital information, and some of it also reverts to an analog signal, which causes the controlled servo element to be controlled to operate. At present, in some mid-to-high-class cars, not only ECUs are used on engines, but also ECUs can be found in many other places, such as ABS systems, four-wheel drive systems, electronically controlled automatic transmissions, active suspension systems, airbag systems, and multi-directional systems. Adjustable electronic control seats are equipped with their own ECU. With the increase of electronic automation of cars, ECUs are increasing and lines are becoming increasingly complex. In order to simplify the circuit and reduce costs, information transmission between multiple ECUs on automobiles will use a technology called multiplexed communication network. The vehicle's ECU forms a network system, which is the CAN data bus.

However, some models are more meticulous in terms of man-machine dialogue. Using ECU, driving data such as outdoor temperature, current speed, instantaneous fuel consumption, average speed, average fuel consumption, remaining fuel mileage, and simple direction guides are collected in the display. Show it, this becomes the driving computer we usually mentioned in the configuration table.
