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

Guangzhou Peugeot introduce

As the earliest joint venture company in China, the Guangzhou logo has left many memories, but the biggest memory is this car. The Guangzhou 505 was the only "failed" car in the Chinese market. At that time, the 505 could be said to have unlimited glory, and the French brought their best car. Its excellent performance, luxurious equipment, and dynamic appearance allowed the Chinese people to experience luxury cars for the first time, Later, a travel model was put into production. It can easily accommodate 8 people running around. A 9-year-old 505 travel model can move at a speed of 200 kilometers per hour, demonstrating the outstanding performance of the 505! A 505 (still an unmaintained bus) that has been in production for over a decade can move forward at a speed of 80 kilometers per hour, which is quite impressive! This is 505, the earliest "good car" to enter China!
