4hw.com.cn: when it comes to the practical configuration of automobiles, there are different opinions. Under the condition that the configuration of various models is the same, some configurations are not impressive but very useful, and some configurations are dazzling but may not be used even after driving for ten years? Recently, my friend is going to buy a car. Apart from the test drive around the forum, there is also an important point. Compared with the configuration, do you need to pay 5000 yuan more for a leather electric heated seat? Can the rear ventilation air conditioning and cruise control be used? Compared with the configuration, it's really a headache. So, which configurations are relatively practical? Here are some relatively practical vehicle configurations. By the way, I'll test your good eyesight and guess which models these drawings come from.
Tire pressure monitoring
Tire pressure monitoring is the real-time automatic monitoring of tire pressure during the driving process, and the alarm of tire leakage and low pressure to ensure driving safety. It is easy to understand that it is the configuration of monitoring tire pressure. According to some data, the proportion of traffic accidents caused by flat tire is as high as 70% in the malignant traffic accidents, and the main reason of all the factors causing flat tire is insufficient tire pressure. I remember a friend once said that when he bought the car, he didn't choose the tire pressure monitoring configuration, his wife didn't check the tire condition before driving, and he drove more than 40 kilometers to go shopping, but he didn't find that the tire pressure was insufficient. If he drove to the high speed, it would easily cause accidents. So even if you don't choose a model with tire pressure monitoring, you should also pay more attention to the tires of vehicles to avoid serious damage to people and vehicles.
PDCParking Distance Control
Reversing radar, i.e. "parking aid device", is mainly composed of ultrasonic sensor, controller and display. Reversing radar is a safety aid device when parking or reversing, which can tell the driver the situation of obstacles around with sound or more intuitive display. Generally speaking, the more sensors, the simpler reversing is. The reversing radar is too practical for many female friends. Sometimes, when the reversing radar and reversing image are installed, there will be a blind area. Foreign matters lower than the car chassis are easy to be ignored. Therefore, it is necessary to install the reversing radar, which can greatly reduce the chance of scratching and collision at low speed.
Body electronic stability system (ESP or ESC)
ESP includes EBD (electronic brake distribution), ABS (anti lock brake system), TCS (tracking control system) and VDC (vehicle dynamic control).
Although they are very detailed and have different functions, they all play a safety role, but they play different roles in different situations. For example, ABS: to prevent wheel lock, the vehicle slip rate is calculated and controlled near the peak adhesion coefficient, which belongs to passive safety control. In fact, the probability of using ESP is not high, but once used, it can save lives, so it is also an essential security configuration. ESP is exclusive to European cars, and Japanese cars are called ESC. They are different in terms of terms and have similar safety functions.
Child seat interface
The common fixed interfaces of child safety seats are latch interface and ISOFIX interface. Latch is common in American vehicles, ISOFIX is common in European brands. Because of the huge impact force of air bags, children under 12 years old can't sit in the front row, the rear row seats and safety belts are not suitable for children's body shape, and there are few air bags, so children's seats have been proved to be the most effective device to improve children's car safety, which can't do without ISOFIX seat interface.
The installation of ISOFIX interface is very simple. As long as the ISOFIX interface of the child safety seat is aligned with the buckle reserved on the seat, it can be installed directly. Finally, the safety of the supporting rod is completed. The installation of children's safety seat has brought safety guarantee to the children in the back row. Every year, there are a lot of propaganda to remind parents to install safety seat for children. There is no mandatory requirement in China, but the use of children's safety seat in foreign countries has been written into the law. It is recommended that parents use the safety seat. The manufacturers are equipped with interfaces, and the car can afford the safety seat, which is not bad The money.
Multifunction steering wheel
Multi function steering wheel refers to the steering wheel that is set with some function keys on both sides or below the steering wheel to make it more convenient for the driver to operate. Of course, the more buttons on the steering wheel, the better. The function buttons with high utilization rate are set on the steering wheel. To avoid using some functions during driving, you have to look down in the central control area to increase the driving safety factor. Before, the multi-functional steering wheel was equipped in some high-end models. At present, the multi-functional steering wheel is a popular trend. More and more models begin to use the multi-functional steering wheel. Although most of them are only limited to the audio control, they provide a lot of convenience and fun for the family car.
Ventilating seat
Seat ventilation is to increase fans on the seat cushion and backrest, use the fans to draw air into the ventilation layer, and then air flow from the surface of the ventilation layer to the surface of the seat cover through the heating pad (the seat cover is made of perforated leather), so that the passengers can use the ventilation function to disperse the sweat on the hip back in hot weather, and bring comfort to the passengers.
But at present, the seats equipped with ventilation function in the market are basically in the middle and high-end models. In fact, the seat ventilation function does have a great impact on the cost. To achieve the ventilation function, many functions need to be added, not only adding a fan, but punching holes in the seat cover is so simple, which is why the models with lower price can not bear the cost of this function, of course, there will be manufacturers to Increasing model competitiveness will increase ventilation configuration as an option for consumers to choose.
As for the practical configuration of the car, the experience will be different according to different personal needs. However, these configurations always play a more or less comfortable or safe role. Obviously, with the same cost-effective model, most consumers will choose one with rich configuration, and how many people are concerned about whether it is chicken ribs configuration.
