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

Ripher introduce

From the feedback from Huapu's car enthusiasts forum, it can be seen that major problems are not common, and small problems are constantly a common problem. Here, I just want to say that there are also quite a few million BMW problems, and everything has problems that are not perfect. The 50000 yuan sedan, at such a low price point, is quite attractive. Based on the information I have learned, let me tell you about the Huapu Langfeng: the predecessor of the current sea area is the Langfeng, Later it was changed to a sea area, and now many of the sea areas on the forum are old models of the Langfeng. This car was once popular, but unfortunately it did not continue to develop. Even the Huapu brand was not retained, and now it has been changed to the UK, a joint venture brand. Currently, the Huapu Langfeng has been discontinued, and because it is an older model, many configurations are not as good as the current car. Therefore, it is recommended that those who purchase a second-hand Huapu Langfeng should change to a different model
