With the development of automotive technology, electronic systems are becoming standard equipment in today's automobiles. Many functions require electronic systems to work together. What are the common electronic systems in automobiles?
A anti-lock braking system (ABS)When it comes to automotive electronic systems, many people first think of ABS, the anti-lock system. Although it is known that the anti-lock system is a very important safety system in the car, most people know it but don't know why. I don't know if the anti-lock system has a flaw. The owner, Tian Zhong, is one of them. “I often hear people talking about anti-lock braking systems, but I don’t know what it is. I only know that it can guarantee the safety of the car while driving.â€
"Anti-lock braking system is when the vehicle is in emergency braking, avoiding the situation that the wheel is locked and the steering wheel cannot be rotated." Industry insider Zhang Li told reporters that with the anti-lock system, the wheels will not lock and improve the emergency system. Directional stability after the move.
The anti-lock braking system was born in the early 20th century and is considered to be the most important technical achievement in terms of safety in addition to safety belts. “The anti-lock braking system is currently quite mature in technology, and most of the models on the market are equipped with this system.†Zhang Li said.
If the warning light on the dashboard of the anti-lock system is on, the owner should pay attention, which indicates that there is a problem with the anti-lock system of the car. "The general anti-lock system warning light is on, there are three cases, one is to control the computer damage; the second is the harness damage; the third is the wheel sensor problem." Zhang Li said, in either case, as long as it is anti-lock If there is a problem with the system, it must be repaired as soon as possible to avoid serious consequences.
B Anti-slip system (ESP)The anti-slip system and the anti-lock system have something in common, because both need to pass the information transmitted by the wheel sensor to judge the driving condition of the vehicle. "If the anti-lock system guarantees the safety of the car during emergency braking, then the anti-slip system is to ensure the safety of the car while driving." Zhang Li said.
The warning light of the anti-slip system is on, and the wheel speed is abnormal. "If one of the four tires has a different tire speed, the light will be on." Zhang Li told reporters that this situation is easy to appear on a car with a modified tire, because the modified tire may have different sizes, once The circumference of the tire is different, and when the anti-skid system is detected, it will be prompted on the dashboard.
When the anti-slip system indicator light is on, if the anti-lock system light is also on, it indicates that there is a problem with the harness of the anti-lock system. Zhang Li suggested: "The prompt lights of the two systems are on at the same time, you can conclude that the wiring harness of the anti-lock system is out of order. If this happens, you need to repair the car as soon as possible."
C Auto Cruise System (CCS)Some time ago, when the owner of the car drove on the highway, he accidentally touched a button. At first he did not find any problems. But not long after, he noticed that a small pointer-like logo on the dashboard was lit. "I don't know what the logo stands for, but for the sake of safety, I chose to park over."
Then Mr. Zhou called the 4S shop and asked what the logo was lit up. The staff told him that it was the performance of the car's own automatic cruise system. Simply step on the brakes or throttle to release the cruise.
What is the automatic cruise system? The automatic cruise system must be turned on when the car travels at a speed of 80 or 90 yards. After that, the car will drive at the current speed, without the driver continuing to control the throttle, not only liberating the driver's feet, but also saving fuel. "This technology has liberated the feet and relieved the driver's burden. Because of its speed limit, it is generally used when driving at high speeds." Zhang Li said.
D tire pressure monitoring system (TPMS)Citizen Wang Chunxia is used to driving to work, and has encountered such an unexpected situation. “On the way to work, I found a yellow light on the dashboard lit up. I felt that there was nothing unusual about driving. I didn’t care. When I got ready to drive home, I found that the tires were a bit awkward and I knew that the tires were leaking.â€
After Wang Chunxia drove the car to the maintenance point, the maintenance master asked her why the tire pressure warning light was on but did not check the tires in time. She suddenly realized that the yellow warning light was the tire pressure warning light.
“The tire pressure monitoring system is very practical. Different tires have different tire pressures. When the tire pressure is lower than the set value, the tire pressure sensor will transmit this information to the vehicle computer, and the tire pressure warning light will light up. Zhang Li introduced the working principle of the tire pressure monitoring system to the reporter.
When the tire first has a problem, the system will prompt the owner to check the tire by illuminating the tire pressure warning light to avoid accidents. However, the system can only monitor the condition of low tire pressure. If the tire pressure is too high, it cannot be monitored.
Zhang Li reminded the majority of car owners: "When pressing the tires, it must be strictly added according to the specified values. The higher the better, the more high the tire pressure will increase the tire wear."
E Battery Monitoring SystemAnyone who has driven a car knows that there is a battery sign on the dashboard of the car. Most people think that the meaning of this sign is to indicate whether the driver's car is turned off. In fact, this sign has other uses.
"If the battery indicator light of a car is on when the car engine is running, it indicates that the car can no longer drive for a long time." Zhang Li told reporters that the battery indicator light is on, indicating that the generator is not working, the generator No longer generate electricity, car lights, air conditioners, etc. need to use the battery's electricity, once the storage capacity is insufficient, it will not be able to support the car for a long time, the car will become a necessity.
"In this case, once the flame is turned off, the car can't be started, that is, it is often said that it does not burn." Zhang Li suggested that if the battery indicator light is on, be sure to find a place to park, then call the 4S shop or The repair station asks for help. Because it is very dangerous to suddenly turn off the fire during driving, the public must not be taken lightly to avoid irreparable damage.
