In other words, there is a popular saying about buying a car: "Buying new is not buying old, just like changing *** However, the "new" here can be interpreted in more than one way in the automotive industry. One "new" refers to the annual renewal of the model, and the other refers to the direct separation of new and used cars. Today, let's talk about the first meaning of this: the old and new choices of automotive technology configuration, especially the relationship between the three "big brothers" and the "wave boy" of cruise control, adaptive cruise and full-speed adaptive cruise.
At the beginning, the big brother of cruise control was born, just like the early big brother could only play **, it is only responsible for allowing you to set a speed comfortably on the highway, regardless of the wind and rain, as long as it does not intervene manually, it will faithfully maintain this speed. As Wuhan Institute of Technology Hu Kefei said in his master's degree**, the cruise control system can automatically adjust the gear and speed through the trip computer to cope with road surface fluctuations and wind resistance changes, and ensure that the engine runs in the best condition. In terms of operation, whether it is the lever type of Toyota Audi or the button type of Mercedes-Benz Volkswagen, novices can easily get started with a little try, but remember to find an open road section, don't practice in the morning and evening rush hour congestion!
Next, adaptive cruise control (ACC), a rising star, is simply an upgraded version of cruise control, which not only inherits the function of maintaining speed, but also learns new skills such as automatic braking and deceleration, and controlling vehicle distance. As Dr. Ma Guocheng pointed out in his research at the Beijing Institute of Technology, ACC uses high-tech sensors and vision systems to monitor the distance from the car in front in real time, and once it finds that the car in front is slowing down, it will automatically help you step on the brakes, just like a caring little follower, what speed you say, it will follow what speed you say, brake in front, it also brakes, the car in front accelerates, it also accelerates, a bit like that cute "copy and paste" mode. As for how to operate, although there are slight differences between major brands, they basically follow the principle of activation setting, one-click start, and easily enjoy the convenience brought by intelligence.
Let's take a look at the "all-rounder" of full-speed adaptive cruise, which completely breaks the speed limit of the original cruise system, expands from the highway to the city road, and realizes the functions of low-speed following, stopping at a red light, and starting at a green light, which greatly alleviates the troubles of driving in urban areas. The research results of Hu Yuanzhi and other scholars in the Journal of Automotive Safety and Energy Conservation show that full-speed adaptive cruise control can work at any speed, especially suitable for complex road conditions in urban areas. Imagine you're driving in the city, even if you don't have to stop and go, just hold the steering wheel and let the clever system do the rest.
Remember, paying attention to the road conditions and driving cautiously is the real master of the road.
