Recently, a friend asked, saying that there is something like egg yolk in the car logo, what is it? I was also stunned for a long time when I got it, now look at it, this thing really looks like an egg yolk. precision cnc customized CNC parts china
An ACC adaptive cruise device (also called millimeter-wave radar), is really convinced by you that it is an egg yolk. In fact, this thing not only looks like egg yolk, but also looks like the following:
You don’t need to step on the accelerator when driving, and you will automatically slow down when you get too close to the car in front… These “magic skills” that look like automatic driving can all be achieved by the ACC adaptive cruise system.
What is ACC adaptive cruise system?
ACC is Adaptive Cruise Control (adaptive cruise control system), which is an intelligent automatic control system, which is developed on the basis of early cruise control technology. Adaptive Cruise Control (ACC) is more intelligent, and generally can enter cruise at a lower speed. In addition to high-speed road conditions, it can also be applied to urban road conditions, and it can be stopped and stopped. precision cnc customized CNC parts china
The ACC adaptive cruise system uses a radar sensor to monitor the traffic conditions in front of the vehicle. The sensor emits radar waves and receives the reflected waves from the vehicle in front. ACC can calculate the position, distance and relative speed to the vehicle in front based on these data.
When the front can drive smoothly, the ACC adaptive cruise system will maintain the set desired speed. If the system recognizes that the vehicle is approaching the vehicle in front, ACC will cooperate with the vehicle through the engine controller or ESP controller to maintain the speed. The set safety distance. When the front is free again, ACC will accelerate the vehicle to a preset desired speed.
Intelligent 5-speed following distance, the driver controls the following distance through the ACC control lever on the left side of the steering wheel. There are 5 gears in total, and the distance will be displayed on the driving computer screen in the center of the vehicle dashboard. precision cnc customized CNC parts china
Personalized follow-up mode, through the central control screen, you can set 3 follow-up modes of ACC cruise (standard, sport, economy), the vehicle will respond differently to the accelerator and brake in different modes to meet different driving needs .
Stop & Go city following car driving system
When the vehicle speed is lower than 30km/h until the vehicle is stationary, the Stop & Go urban follow-up driving system is activated. This system can still maintain the distance from the vehicle in front when driving at low speeds, and can brake the vehicle until it is stationary. . If the vehicle in front starts again within 3 seconds, the vehicle will start automatically. If the vehicle in front stays for a long time, the driver can easily enter the ACC follow-up mode through simple operations, such as lightly stepping on the accelerator pedal. In this way, the ACC stop-and-go function can assist driving even in rush hour or congested road sections.
When driving a conventional vehicle, the driver must remain fully focused, quickly spot new situations and react by braking or accelerating. The ACC adaptive cruise control system can adjust the speed of the vehicle according to the traffic flow and help maintain the distance between the driver and the vehicle in front, thereby reducing the burden on the driver during driving and allowing the driver to better focus on the current situation. Traffic conditions make driving easier. Obviously, ACC can reduce the driver’s driving fatigue to a certain extent.precision cnc customized CNC parts china
ACC is so amazing, can it be completely relied on?
As an intelligent driving technology, ACC is the future development direction of automobiles, but the current ACC is still in the further exploration stage. After all, it cannot be as intelligent as a human being, able to distinguish all road conditions and respond accordingly. At present, ACC is mainly used on roads with better road conditions (high-speed or elevated), and it is the judgment of the target vehicle in the main lane, so human intervention is still necessary during use.
Precautions:
The ACC adaptive cruise system is just a driving assistance system that focuses on comfort, not an automatic driving system. Therefore, even when ACC is engaged, it is the driver’s responsibility to monitor the speed of the vehicle and the distance to the vehicle in front at all times. The driver can control the vehicle at any time by braking or accelerating.
ACC is helpful to achieve coordinated and smooth car-following, but there are still some special working conditions that require users to pay special attention to. precision cnc customized CNC parts china
