ADAS (Advanced Driver Assistance System), the advanced driver assistance system, has attracted much attention in recent years as a transitional stage for achieving driverless driving. In general, ADAS uses a variety of sensors installed in the car to collect environmental data inside and outside the vehicle, identify or detect people or things that are still or in motion, so that the driver can Quickly detect the dangers that may occur, to attract attention and improve safety with active safety techniques.
After careful study, ADAS contains many different technologies, such as: ACC adaptive cruise, AEB/CMbB automatic emergency braking, TSR/TSI traffic sign recognition, BSD/BLIS blind spot detection, LCA/LCMA lane change assistance, LDW lane departure Early warning. Let's take a closer look at the features that each part has.
01 lane offset alarm system + lane keepingThe system consists of a camera, a sensor and a controller. The principle is to use the camera on the side of the vehicle body or the rear view mirror to sample the marking line of the current driving lane, and then through image processing to obtain the position of the current car in the lane. When the car deviates from the lane, the controller will send out an alarm signal. From the perception to the alarm, the process takes about 0.5 seconds to remind and wake the driver in real time to avoid accidents.
The sensor such as a radar camera mounted on the vehicle detects the speed of the vehicle and the distance and speed of the vehicle in front. Initially, a warning sound is issued to remind the driver to pay attention to the distance. If the driver does not respond, the distance between the vehicles continues to be close. The system will intervene to give a certain braking effect to prevent collision.
The blind spot of a car driver refers to the three-sided rearview mirror, which is invisible to the left, right, and inside. It is believed that many drivers are deeply impressed by the blind spot. It is also one of the many accidents that often occur in many accidents. The blind spot detection system uses radar and sensors to detect the blind spot area behind the vehicle. When the blind spot area detects the approach of the vehicle, it will provide warning to the driver to help the driver minimize the chance of accident.
The APA automatic parking system uses infrared or sensors to detect objects around the car. These sensors emit signals that are reflected back when the signal hits an obstacle around the body. The computer on the car uses the time it takes to receive the signal. Determine the location of the obstacle, then the computer system will take over the steering wheel, and the computer will turn the wheel through the power steering system to completely pour the car into the parking space.
The ACC adaptive cruise system mainly detects the speed and relative distance of the preceding vehicle through the distance sensor installed at the front of the vehicle, continuously scanning the road ahead of the vehicle, and automatically detects the speed when driving, when the distance from the preceding vehicle is more and more In hours, it will adjust its own speed, keep a safe distance from the vehicle ahead, and reduce the occurrence of collision accidents.
At present, most of the systems use cameras to detect the driver's face, determine the degree of concentration, whether there is a symbol of dozing, and the system uses the driver's eyes to open and close the frequency to identify the safety level and provide appropriate warnings. Or assist the action, if the driver's facial expression changes less, or even close the eyes, the vehicle will alert the owner through the sound and the light to reduce accidents.
This system can automatically adjust the lighting range and angle of the lights according to different road conditions, environment, speed and weather conditions, so that the illumination range of the lights can be farther and farther, without affecting the sight of other passers-by to provide to the driver. More safe and comfortable lighting with the car.
It can help drivers automatically identify animals or large foreign objects when the line of sight is unclear, unclear, or bad weather, and warn the driver of the road ahead to avoid accidents. The way to distinguish is to use infrared light to sense the difference in heat, to distinguish between people, animals, vehicles and the environment. After processing, it is transformed into an image, and the originally unclear objects are clearly presented in front of the driver to reduce the risk of driving.
In addition to the above eight systems, the ADAS system also includes: navigation system, real-time traffic system, electronic police system, car networking system, downhill control system and so on.
Each system of ADAS consists of three main levels:
The sensing layer, that is, the collection of information, different systems need to collect the vehicle's operating state and surrounding environment changes by different types of vehicle sensors (including cameras, radar, etc.), and feedback to the control unit in time.
The control layer analyzes and processes the information collected by the sensor, and then outputs a control signal to the controlled device.
The executive layer, according to the signal output by the driving computer, allows the car to complete the specified action.
Disposable Vape Kit is all-in-one vaping device for starters and people who aim to get rid of smoking. At the year of 2017, JUUL released new generation Nic Salt, the disposable vape pen started to enter market, and get popular on America, Europe.
Since then, e cigarette vape manufacturers are booming. New technology and multi-flavors bring small e cigarette vivid life. It is sample to use, and portable, direct draw mechanism, pre-filled e juice, pre-charged battery, cotton coil or ceramic coil let vaping device an ideal choice for people on the go.
Compared to large vapor e cigarette, disposable vapes require no charging or re-filling, no other complicated settings. Just pick it up, remove the package, and take a drag, you will get amazing Nic satisfaction, life is enjoyable more than ever.
