Where is cruise control or adaptive cruise control?

1. Adaptive cruise, that is, the computer controls the distance between the vehicles through the radar, and the distance between the vehicles is too close to automatically brake, reducing the power, and the distance between the vehicles is too long, and it will automatically accelerate. Stay at the distance and speed you set. What is more advanced now is that when the car in front stops, your car stops, and the car in front goes, and your car goes.

Fully intelligent.

2. Cruise control is to keep a speed all the time, which is more fuel-efficient. You don't need to step on the gas pedal anymore. The technological content and positioning of adaptive cruise control are there, so low-end cars are not possible, at least mid-level cars.

1. Cruise control system (cruise

control

system)

Abbreviated as CCS, also known as fixed-speed cruise driving device, speed control system, automatic driving system, etc. Its function is: after closing the switch at the speed required by the driver, it automatically maintains the speed of the vehicle without pressing the accelerator pedal, so that the vehicle runs at a fixed speed.

2. Adaptive cruise control is an intelligent automatic control system, which is developed on the basis of the long-standing cruise control technology. While the vehicle is moving, a distance sensor (radar) mounted on the front of the vehicle continuously scans the road in front of the vehicle, while the wheel speed sensor collects the vehicle speed signal.

The correct way to turn on cruise control.

It can replace cruise control. ACC adaptive cruise.

Adjustment allows the vehicle's cruise control system to adjust the speed to suit the travel situation, whereas traditional cruise control simply adjusts the speed of the vehicle. The function of cruise control is to automatically maintain the speed of the vehicle without stepping on the accelerator pedal after closing the switch at the speed required by the driver, so that the vehicle can drive at a fixed speed.

1. Cruise control is to drive at the speed set by the driver, turn on this function, the driver's foot does not need to step on the accelerator pedal, the car will drive at a fixed speed, the research and development of this function is intended to reduce the fatigue of the driver for long-distance driving, and at the same time reduce unnecessary speed changes, which can save fuel and improve fuel economy.

In principle, cruise control should be used on highways or fully enclosed roads. Because on non-closed roads, complex road conditions are not conducive to traffic safety. In addition, it is forbidden in rainy and snowy days and mountain roads, especially when there are many vehicles, and it is not known that it is conducive to traffic safety.

2. Adaptive cruise is also known as ACC, which is more intelligent than cruise control, and is developed on the basis of cruise control technology. The main thing is that a new sensor is added around the body, that is, the radar, which can detect a certain range of obstacles around the body in real time, and after calculating and processing it through the driving computer, it can react to the operation of the vehicle, such as deceleration. This feature is equivalent to a simplified version of self-opening banquet sliding driving.

It's a semi-autonomous driving function.

Difference Between Cruise Control and Adaptive Cruise.

1. Functional differencesFrom a functional point of view, the biggest difference between the two is that the adaptive cruise system can follow the car in front, while the cruise control cannot follow the car. This means cruise control system.

The driver sets how much speed, regardless of whether there is a car in front of him to drive at this speed, and adaptive cruise control not only has the function of cruise control, but also can automatically slow down to follow the car in front and maintain a certain distance when there is a target vehicle in front.

Adaptive cruise control is smarter, smarter, and closer to unmanned. Once set, it will automatically determine whether to refuel or brake cruise control based on the distance of the car in front, and as the name suggests, it moves at a fixed speed at a constant speed. The system cannot automatically determine whether it is time to brake or accelerate, but needs the owner to make an accurate judgment at the right time according to the road conditions.

2. The structure of the cruise control system is very simple, theoretically speaking, the system is only set with a fixed throttle after opening. Adaptive cruise system, its structure is more complex, installed with many monitoring modules, such as radar ranging module, if coupled with the image recognition module, it is basically equivalent to unmanned driving.

Adaptive cruise has a fixed speed cruise function, and adaptive cruise is based on the control of speed of fixed speed cruise to further realize the grasp of distance. To put it simply, there is only one thing to do in cruise control, which is to meet the driver's preset speed requirements, and adaptive cruise control not only achieves the preset speed, but also shoulders the task of maintaining the preset following distance and accelerating and decelerating as the distance changes.

Now, long-distance driving, with the help of adaptive cruise, has freed up the feet of some drivers. So how does this guy who can automatically reach the preset speed and maintain the preset following distance do all this? Why does adaptive cruise sometimes accelerate or decelerate suddenly when entering a corner?

Before answering the above questions, we first need to understand what the structure of adaptive cruise is and what its judgment logic is. Once the structure and principle are understood, it will be easy to solve practical application problems.

What is Adaptive Cruise? Is it different from cruise control?

The first thing to affirm is that there is a difference between adaptive cruise control and cruise control. The development of science and technology has helped more and more cars to equip with cruise control systems, and adaptive cruise control is based on the control of speed control by cruise control to further realize the grasp of distance. To put it simply, there is only one thing to do in cruise control, which is to meet the driver's preset speed requirements, and adaptive cruise control not only achieves the preset speed, but also shoulders the task of maintaining the preset following distance and automatically accelerating and decelerating as the distance changes.

Generally speaking, the adaptive cruise system is composed of three parts: sensors, digital signal processors and control modules. If you use human beings as an analogy, the sensor is similar to the eyes, ears, nose and other organs, it is responsible for perceiving the car in front and the exact location of the car. The signal processor is responsible for digitizing the information received by the sensor, and finally the control module processes the collected information for control.

When the system judges that it is necessary to slow down, the ABS system finally brakes the wheels or the gearbox adopts a downshift method to reduce the vehicle speed.

Sensor installation locationAt present, the sensors on the market mainly include radar sensors, infrared beam sensors and first-class cameras. Different brands and models have different installation positions, and the common installation positions are behind the car logo, on both sides of the bumper, under and behind the rearview mirror. The main reason for these differences is the different operating principles of the various sensors, but also some of the cost factors.

Adaptive cruise control is cruise control, and cruise control (CCS) vehicles equipped with speed control functions can be manual transmission models or automatic transmission models. Cruise control can be used at a speed of 30km-150km, depending on the situation of each model, and is not a uniform value.

Cruise control is to drive at the speed set by the driver, and when this function is turned on, there is no need to press the accelerator pedal, and the vehicle will drive at the set speed. Adaptive cruise control is more intelligent, and can maintain a safe distance from the vehicle in front at all times, or automatically brake the car to slow down until it stops when the vehicle in front slows down, and always maintains a safe distance from the vehicle in front.

Now many models are equipped with cruise control configuration, and adaptive cruise this configuration, generally in the high-end models will be equipped, different brand models, the steering wheel on the speed and adaptive cruise operation button position is somewhat different, you can refer to the vehicle manual, but the control principle of cruise control and adaptive cruise is similar.

Adaptive cruise control (ACC) can only be sold by automatic transmission models, because adaptive cruise control is not a fixed speed driving, and the speed changes at any time, so automatic transmission models are required to be equipped with this function.

Adaptive endurance is divided into: ordinary adaptive endurance (simple speed control), full-speed adaptive cruise (intelligent driving) Adaptive cruise is more intelligent than constant speed cruise, but the system is only used to assist the driver, not a collision avoidance device, such as other vehicles into the front lane or the vehicle in front of the vehicle to slow down rapidly, the distance between vehicles may be closer. If this happens, it's a good idea to brake as well to avoid a collision with the vehicle in front.

Whether it is cruise control or adaptive cruise, it is to make it more convenient for the driver and provide the driver with a more comfortable driving experience, but as a function, although he can automatically adjust the speed, sometimes there will be mistakes, so we still have to concentrate on driving.

The adaptive cruise control system is not a fixed-speed cruise. Adaptive cruise control is an upgraded version of cruise control. Adaptive cruise can be used on urban roads and can be used in any speed range.

Cruise control systems are not so intelligent, and this kind of system is generally not available on urban roads, only on highways, and not in any speed range.

Many high-end cars will be equipped with adaptive cruise control, and cars equipped with adaptive cruise control will have a radar under the front bumper, which is used to detect the distance between the car and the vehicle in front.

Cars equipped with adaptive patrol Sun Zhizhou Airlines also have an automatic following function, which makes it quite easy for the driver to turn on this function.

Some cars will be equipped with Level 2 autonomous driving technology, and cars equipped with Level 2 autonomous driving technology will definitely be equipped with adaptive cruise control systems.

If you are interested in a car equipped with an adaptive cruise system, you can go to a 4S store to test drive a car equipped with this system.

The adaptive cruise control system can reduce the labor intensity of the driver, and this system is especially useful on urban roads with traffic jams.

If you are driving in some traffic jams, you can set the following distance so that the driver does not have to press the brakes and accelerator repeatedly.

But when using adaptive cruise control, the driver also needs to stay focused.

Adaptive cruise can cruise at a fixed speed, and since adaptive cruise is an upgraded version of cruise control, it is more flexible and intelligent to use. If cruise control liberates the feet, then adaptive cruise is close to autopilot. Adaptive cruise radar can scan the surrounding traffic conditions to determine whether the vehicle accelerates or decelerates, so as to maintain a safe driving distance, which is a very good driving aid.

Yes, the adaptive cruise system consists of three parts: sensors, digital signal processors and control modules. To use a human analogy, sensors are similar to organs, such as eyes, ears, and noses, which are responsible for sensing the vehicle in front and the exact location of the vehicle. At present, common sensors include radar sensors, infrared beams, and ** cameras.

ACC adaptive cruise control can replace cruise control

1. ACC adaptive cruise adjustment allows the vehicle cruise adjustment system to adjust the speed to adapt to the cruise of the travel situation, and the traditional cruise only adjusts the speed of the vehicle unchanged;

2. ACC adaptive cruise is only available in high-end cars, such as Volkswagen CC, Ford Mondeo and other medium-sized cars or luxury brands such as Mercedes-Benz BMW; Most of the medium configuration basically only has traditional cruise control, and some low configuration does not even have cruise control;

3. ACC adaptive cruise control is intelligent, and the speed can be adjusted through sensors. Traditional cruise control is mechanical, and the speed of the vehicle can only be adjusted by applying the brakes;

4. The function of cruise control is to automatically maintain the speed of the vehicle without stepping on the accelerator pedal after closing and closing the Yelingsen according to the speed required by the driver, so that the vehicle can drive at a fixed speed. However, cruise control has a significant disadvantage, that is, it can only supply a constant speed compared to cruise control;

5. ACC adaptive cruise control can adjust the speed of the vehicle according to the change of the environment, when the distance between the car is too close, the driving computer will automatically adjust the accelerator and brake the car, and actively reduce the speed to maintain a reasonable safety distance; When the following distance is reached, the previously set cruising speed will be automatically restored.
