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

Mercedes Benz CLK introduce

The Mercedes Benz CLK is a new model of Mercedes Benz, and the CLK class sports car will be launched with a new face on the basis of the E-Class. Its interior space is more spacious, the wind resistance coefficient is lower, and the power is stronger. The model consists of a roof, electronic stability program, lighting system, head airbag, automatic rollover guard, sports package, and model overview. Due to the extended wheelbase of the 2003 CLK sports car, it is generally longer, wider, and higher than the old version, The cabin space is also wider. The strength of the car body has increased by 40%, and the drag coefficient has been reduced to 0.28cd. The side windows adopt frameless design technology, which can fully retract the doors and side body. The safety configuration of the 2003 CLK mainly includes front and side airbags, side window airbags, pre tension seat belts, and impact force limiting devices. The interior decoration materials can be selected from wood or aluminum according to personal preferences, but all CLK instruments are wrapped in chrome alloy. The rear seats are foldable, This can increase storage space. Other standard devices include wipers with sensing system, headlight assist device, and air conditioning control device. Optional parts include automatic cruise control system, xenon headlights, and voice controlled telephone. In 2010, with the release of the new generation of E-Class sedans, Mercedes Benz launched E-Coupe, which is no longer used in CLK class sports car models
