In the eyes of many friends, cruise control means that the car runs by itself, which is quite unreliable and unwilling to use it. There is a paper in "Science and Technology Innovation Herald", the research and implementation of automobile cruise control system says that cruise control is also an automatic driving function, which keeps the speed by collecting road information from the ECU of the automobile. This means that you don't need to control the speed of a car that has been cruising at a constant speed, right?
There is also a paper on the driver's "sense of security" in the journal Automobile Driver. Only when the driver has the ability to accurately control the driving of the vehicle and accurately perceive the traffic conditions can the driver feel safe when driving the vehicle, otherwise the driver will feel unsafe when driving.
Not using it does not mean that the cruise technology is poor.
Wuhan University of Technology also has a paper "Design of Constant Speed Cruise System". Constant speed cruise began to develop in the 1960s. From the original mechanical cruise control system to the present intelligent cruise control system, the technology has gradually matured.
On 20 18, there was a news that Mercedes-Benz cruise was out of control. According to the appraisal report of the third-party authoritative organization, it is a farce that Mercedes-Benz cruise is not out of control. On the contrary, this matter put an advertisement for the cruise at a fixed speed, which proved to be very reliable. In fact, even if the cruise control is out of control, it can be remedied or operated back, because the braking system is independent of the cruise control system. Moreover, the constant-speed cruise can be forcibly closed by putting in neutral, downshifting, or pressing the engine start-stop button for a long time. They must have wanted it.
Constant speed cruise is not as practical as ACC.
Zhuhai College of Beijing Institute of Technology has a paper, the overall structure design of automobile constant speed cruise control system. If the cruise control system of an automobile wants to keep the vehicle running at a constant speed, it needs to adjust the throttle opening to achieve power balance.
Generally, the speed of cars is less than 40km/h, so cruise at fixed speed doesn't work. Some cars may be 30 km/h, and when there are few cars, it is easy to talk about it. When I get to and from work, I get stuck there, which can't trigger this kind of thing at all. How to use it?
Data Eye & Jacky Data Center released 20 16 China traffic congestion analysis. First-tier cities are the most congested. The average speed of car owners in Shanghai is only 23km/h per month. Well, how to cruise at a fixed speed? Shenzhen is fast, even in developed cities. How many months on average? 28km/h, but it didn't reach 40km/h anyway.
Driving in such a blocked city, you can't even drive at a fixed speed. You traveled to ancient times with a 5G mobile phone. There is no base station and no charger. Your mobile phone has become a plastic case. What do you think of the program "Spare tire says car"? Right?
High-speed is not easy to use: it is not as good as ACC in traffic jams.
Except in urban areas, cruising at a constant speed at high speed is still not practical, just use a spacious high speed. There is a paper in Science and Technology Vision magazine, which describes the functions and precautions of cruise control system.
There are many opportunities for vehicles to cruise at a fixed speed during long-distance driving. When driving on the expressway for a long time, you can start constant speed cruise under certain conditions. But in the case of traffic jams and speed limit changes, it is not so useful.
Gong Li University in Shenyang has a paper, the design of adaptive cruise control system for automobiles. Constant speed cruise has a single function and is not intelligent enough, so ACC (Adaptive Cruise Control System) is still needed in road conditions that require different speeds.
ACC is a function based on cruise control, which is a little more advanced than cruise control. It changes the speed according to the vehicles or obstacles in front, which is safer and smarter.
Constant speed cruising is also easy to make people sleepy.
Cruise at a fixed speed may hypnotize our drivers, which is one of the reasons why many people are unwilling to use it. Once you cruise at a constant speed, you don't have to worry about your feet. It will take care of itself. It's very comfortable when you rest, and you want to sleep when you feel comfortable, especially after driving for a long time, right? There is a paper in Science Times, which mentioned the causes and preventive measures of traffic accidents caused by fatigue driving.
Driving on the highway, the scenery along the way is relatively simple, the driver's driving action is also relatively monotonous, and the line of sight is relatively simple. Driving in a relatively stable and comfortable environment for a long time, without any accidents or twists and turns, will lead to hypnosis, and people are more likely to get tired.
I don't want to use it because I don't think it is practical.
Most car owners don't want to cruise at a fixed speed, or because they feel unreliable, impractical or even dozing off. I buy this car, and I don't want to pay more for this configuration.
How to use constant speed cruise in the car?
But in fact, cruise control is helpful to drivers, which requires some skills to achieve. You bought this car and a mid-equipped skylight. There happened to be a cruise at a fixed speed. Do you want to use it? Help scientifically without dozing off? We have a routine for this configuration and method.
