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

The highly anticipated Volkswagen's first domestically produced SUV, the Tiguan, received reliable news in February 2010 and will announce its price on March 26, 2010. This compact SUV first met consumers at the 2009 Guangzhou Auto Show and gained widespread attention and love upon its appearance. The appearance of the Tiguan broke the awkward situation of German cars without domestically produced SUV products, At the same time, it also provides consumers with more and better choices. Currently, the Tiguan has been exhibited at Volkswagen 4S stores in Shanghai, Beijing, for consumers to further understand. Volkswagen Tiguan is equipped with a variety of safety features this time, and the entire series is equipped with an ESP body stability system as standard EBD electronic brake force distribution and ASR traction control, such as some rare EDS electronic differential locks The EPB electronic handbrake, automatic parking function, and TPR tire pressure monitoring system have all become standard features of the Tiguan, indicating that Volkswagen attaches great importance to safety. The front double airbags and front side airbags can ensure the driving safety of passengers, and the standard child lock also values the safety of children. In short, the Tiguan's sincerity in safety configuration is enough to impress the Chinese people
