Car computer price is one of the important factors to consider when buying a new car. With the rapid development of technology, automotive computer systems are playing an increasingly important role in modern cars. These computer systems not only provide vehicles with functions such as navigation, safety, and entertainment, but also provide valuable driving information through data entry and analysis. Therefore, knowing the price of a car computer is critical in deciding which model to purchase and in planning your budget.
Car computer prices are affected by many factors. First of all, the prices of automobile computer systems of different brands and models vary greatly. Mainstream car brands such as Audi, BMW, and Mercedes-Benz tend to invest more in R&D and technology, so their computer systems are more expensive. Relatively speaking, the computer systems of some economical models are relatively affordable.
Secondly, the functions and performance of the car computer system have a significant impact on the price. The computer systems of some high-end models have advanced navigation, intelligent driving assistance, in-car entertainment and other functions. These features not only require higher hardware configurations, but also require more complex software development. As a result, high-performance automotive computer systems tend to be more expensive.
In addition, the supporting equipment and sensors associated with the car computer system will also have a certain impact on the price. For example, advanced driver assistance systems require more cameras, radars, and laser sensors, which will increase the cost of automotive computer systems. Therefore, the increase in the number of supporting equipment and sensors will lead to an increase in the price of automotive computers.
With the continuous advancement and popularization of car computer technology, car computer prices are showing a certain trend. First of all, with the rapid development of intelligent driving technology, the price of automobile computer systems is gradually declining. The maturity of intelligent driving technology and the reduction of costs have made intelligent driving functions gradually enter mainstream models. Relatively speaking, the price of automobile computer systems required for intelligent driving will also decrease accordingly.
Secondly, the price of data-driven automotive computer systems is also expected to drop. With the rapid development of Internet of Things and big data technology, cars are able to collect and analyze large amounts of driving data to provide more accurate driving experience and guidance.

Connecting a certain part of the power system or electrical installation to the ground electrode through a ground wire is called grounding. The wire connected to the ground electrode is called the ground wire. The ground electrode and ground wire are collectively called the grounding device.
Several grounding bodies are connected to each other in the earth to form a grounding network. Grounding wires can be divided into grounding trunk lines and grounding branch lines. According to regulations, the grounding trunk line should use no less than two conductors to connect to the grounding grid at different locations.
The grounded point in the power system is generally the neutral point. The grounded part of an electrical device is an exposed conductive part. It is a conductive part of an electrical device that can be touched. It is not charged normally but may be charged under fault conditions.
The external conductive part of the device is also called the external conductive part. It does not belong to the electrical device. It is generally the metal pipes of water, heating, gas, air conditioning and the metal structure of the building.
The car power supply system consists of a battery, a generator and an elegant regulator. It is the power supply system of the car's electrical system, providing sufficient electrical power and stable working voltage for the car's electrical system.
The car power supply is powered by the battery and generator in parallel. When the generator is running, it outputs current to drive the DC load, but the internal capacitance of the generator is too large, so it cannot output fast switching current. Then this task must be completed by the battery.
In addition, the first consideration of the car grounding system is to ensure the correct operation of the starter, so we must also consider the requirements of the starter. To ensure that the starter motor can operate in cold weather.
The current loop must show DC low resistance characteristics between the negative terminal of the battery and the starter ground (generally the engine body). The mounting location of the starter and battery may create additional unfavorable current loops between this ground conductor.
Under normal circumstances, the life of the car computer is equal to the life of the car, or even longer than the life of the car. When the car reaches the end of life, the driving computer is still normal, because the driving computer is the core device of the car and the components used are all It is made of high-quality imported components and has been finalized after rigorous aging experiments and experiments under harsh working conditions. Therefore, the service life of the trip computer is very long.

Car computer maintenance equipment is equipment used to diagnose and repair automobile electronic control systems, including diagnostic instruments, programmers, readers, testers, etc. These devices can help car maintenance personnel detect and repair car faults accurately and quickly, improving maintenance efficiency and accuracy.
With the development of modern automobile electronic technology, in automobile air conditioning systems, whether it is manually controlled or automatically controlled air conditioners, the cutting off and engagement of the compressor electromagnetic clutch are generally controlled by computers.
During the maintenance process of the air conditioning system, a considerable number of faults occur on the computer. When all sensor signals can be input to the computer normally, if the computer cannot correctly control the separation and engagement of the compressor electromagnetic clutch, the fault will mostly occur in a triode inside the computer that acts as a switch.
Repairing the air-conditioning control failure of most computers actually means replacing the relevant switching transistors in the computer. Let's take the Honda Accord sedan as an example to introduce the methods and steps of computer repair.
The first step is to find the connecting end of the electromagnetic clutch control coil and the computer and the grounding end of the computer according to the circuit diagram. It is best to use a colored pen to find the terminal and mark it.
The second step is to use the digital multimeter to measure the on-off switch, starting from the determined air-conditioning control terminal, and searching inward along the printed circuit of the computer little by little until you find a certain triode or triode row.
The third step is to determine the three pins of the triode or triode row. NPN type triodes are generally used in computers. Here we take the NPN type as an example. The pin corresponding to the printed circuit found in the previous step is the collector of the triode, and the thin printed line next to it is the base of the triode.
Of course, we need to further confirm whether it is the left one or the right one. The confirmation method is as follows: Set the air conditioner operation panel to the air conditioning cooling operation state, use the voltage block of the multimeter to connect to a base line to be confirmed, turn on the A/C switch, it should display 5V, and when the switch is turned off, it should display 0V. Use this method to test these two wires and repeatedly confirm that the one that meets the conditions is the base. When confirming the emitter, generally if it is a triode row, its emission peaks are mostly at both ends of the row. Use a multimeter to measure the on-off block. One end is connected to the ground terminal of the computer, and the other end is connected to the ground terminal considered to be the row. It can conduct The connected pin is the emitter of the triode. If there is only one triode, it can be easily recognized by the thickness of the printed circuit.
The fourth step is to find a replacement triode. The transistor to be replaced may be an independent triode (Nissan), a triode directly embedded on the circuit board (Charade), or a triode in a triode row (Honda). This kind of transistor can generally be found in old automotive electrical components. The determination method can be roughly based on the following aspects:
(1) Look at the model. The transistor models produced in Japan are generally 2SA (NPN), 2SC (NPN) and 2SD (PNP). The replacement component models available in the domestic electronics market are: BT179 and BT178. The models of triode banks are generally: 2003 and 1413.
(2) Look at the appearance. This type of triode should have three legs, and its shape should be basically the same as the original triode. It is generally a flat triode. The size can be a secondary consideration. Whether there are holes and heat sinks is not important.
(3) Look at the resistance. The base of the triode is generally connected with a resistor in series, and the resistance of the base should be similar to the resistance of the original triode. The resistance value of the resistor is determined as follows: the corresponding numbers for brown, red, orange, yellow, green, blue, purple, gray, white and black are: 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0, for example, brown, black, and black represent 1,000. Since the base of the transistor is controlled by the size of the current, and the computer voltage value is fixed, a resistor must be used to control the current. If the current is too high, the transistor will be burned, and if the current is too small, it cannot be triggered.
(4) Measurement confirmation. Remove the roughly determined triode from the circuit board and use the diode measuring block of the multimeter to measure the properties of the triode. According to the properties of the triode, only one pin should be conductive in one direction relative to the other two pins. With this property, it can be determined that it is a triode, and a pair of pins that are conductive in one direction is a field effect transistor. The pin that is conductive relative to the other two pins is the base of the triode.
Then select the measurement mode of the triode of the digital multimeter, insert the base of the triode into B, and insert the other two pins into C and E respectively. If the displayed value is between 200 and 300, it proves that the pins are plugged in correctly. C represents the set. Electrode, E represents the emitter. Then determine whether the triode is PNP type or NPN type. P is the positive pole and N is the negative pole. The selected triode is then soldered to the circuit board.
