Trip Computer introduce

The driving computer (ECU) is generally used in electronic fuel injection vehicles. It is generally used to control fuel injection rate, mixture ratio, etc. It is composed of a microcomputer and peripheral circuits. The microcomputer is a unit that integrates a microprocessor (CPU), memory, and input/output interfaces on a single chip. Its main part is the microcomputer, and the core component is the CPU The ECU converts the input signal into digital form, compares and processes it based on stored reference data, calculates the output value, and then amplifies the output signal to control several regulating servo components, such as relays and switches ECU is actually an "Electronic Control Unit", which is composed of three parts: input circuit, microcomputer, and output circuit. The input circuit receives signals from sensors and other devices, filters and amplifies the signals, and then converts them into a certain voltage input level. The signals sent from the sensor to the ECU input circuit include both analog and digital signals, The analog-to-digital converter in the input circuit can convert analog signals into digital signals, which are then transmitted to the microcomputer. The microcomputer processes the preprocessed signals and sends the processed data to the output circuit. The output circuit amplifies the power of digital information, some of which need to be restored to analog signals, to drive the controlled regulating servo components to work)

Location of onboard computer/OBD onboard computer

The onboard computer is usually located in front of the central armrest. The onboard computer is installed in the driver's cab, which is under the steering wheel. The onboard computer is in computer-controlled mode Car mounted computer is a specialized information product developed for the special operating environment and electrical circuit characteristics of automobiles. It has high temperature resistance, dust prevention, and seismic resistance functions and can be integrated with automotive electronic circuits. It is a highly integrated multimedia entertainment information center for automobiles It can achieve all the functions of a home computer, including in car internet access, video entertainment, satellite positioning, voice navigation, gaming, telephone and other functions. It can also achieve specific functions such as visual reverse and fault detection. Its main functions include comprehensive multimedia entertainment GPS satellite navigation, professional diagnosis of car information and faults, as well as mobile office and industrial applications. Currently, only top foreign models such as BMW and Audi are equipped with similar intelligent in car systems

桑塔那 introduce

In the late 1990s, Shanghai Volkswagen Co., Ltd. developed the "Shanghai Santana 2000" sedan, aiming to sprint towards the 21st century and challenge the future, sparking a "new Santana" whirlwind on the coast of the East China Sea in China The Santana brand has been deeply rooted in people's hearts in China for 20 years, but unfortunately, shopping malls are like battlefields. The current automotive market is full of gunpowder. The Santana 2000 was discontinued on January 31, 2004, and the replacement model, the Transcender (Santana 3000), was officially produced on February 1, 2004. Shanghai Dazhong claimed that the title of the "Transcender" of the Santana 3000 model is called "Modern Classic Car", which means "Modern Technology. Classic Model", On the one hand, it is because the Santana has become a classic model, and the "Transcender" continues the brand spirit of the Santana; On the other hand, the Transcender also adopts relatively advanced technologies, such as variable frequency air conditioning
