Active safety makes cars "impeccable"
The car, one of humanity's greatest inventions. After Carl Mercedes invented the first car in 1886, mankind constantly improved it, and in the process, "security" has gradually become one of the most important performances of engineers. In the past, the speed of the car was slow, and even if there was a collision, it would not cause major losses. With the advancement of automotive powertrain technology, cars are becoming faster and faster, and the accident rate is also rising, which makes people pay attention to cars. safety. Engineers began to thicken automobile steel plates and strengthen material strength. This is what we will call passive safety technology. Later, as the speed of the car further increased and the number of cars increased, the passive safety technology itself could not guarantee the safety of the car. It coincided with the booming development of automotive electronics technology. The active safety technology based on this came into being.

Active safety technology is a technology that helps drivers to mitigate and avoid accidents when they can't avoid accidents. It is a field that major car manufacturers and parts suppliers pay great attention to today. After years of development, it has become more and more. The more advanced it is, it is now commonly referred to in the industry as Advanced Driver Assistance Systems (ADAS). For example, in the past, active safety systems only served as a warning when the car deviated from the lane. Now, the system has evolved into a lane keeping system that helps the car stay in its original lane. Gasgoo.com will inventory the most advanced active safety technologies in this article.
Volvo Cars has always been known for safety. The collision mitigation system in its V40 model can implement a variety of safety functions, such as adaptive cruise control, vehicle frontal collision alarm with automatic braking system for pedestrians and vehicles, and pre-collision detection. Lane keeping assist, automatic headlight control and traffic light identification. In addition, regarding the safety of the rear and sides of the vehicle, the V40 uses a rear-end and two-side detection system to realize functions such as blind spot detection, lane change assistance, and intersection warning.
In 2013, Volvo introduced a pedestrian/cyclist collision detection system with an automatic braking function. This system not only detects pedestrians and cyclists in the front and warns drivers, but also can take the initiative in the event of a driver’s unresponsiveness. brake. AOLAutos, a well-known foreign automotive media, has named this technology one of the best technologies of the year. The system uses a radar to evaluate the speed of the front object, and works in conjunction with a quick camera to evaluate the outline and size of the front object. The two continuously monitor the trajectory of the object and prepare for warning in real time.
Safety is an increasingly important factor for car buyers. Ford Mondeo also has a good reputation for safety and quality. New Mondeo is equipped with a series of leading-edge active safety technologies in its class. The new Mondeo ACC intelligent adaptive cruise system can automatically adjust the speed. When there is no car at the front, the set speed will be maintained; when there is a car at the front, the intelligent adaptive cruise system will automatically adjust the speed and maintain the set distance from the front car. The intelligent adaptive cruise system uses a microwave radar, which has good real-time performance and a wide range of detection angles. It also improves fuel efficiency while reducing fatigue driving. It is very practical for users to drive on regular highways.
In addition, the new active parking assistance system in the new Mondeo can help owners to easily stop, greatly improving the convenience of the owner parking; blind spot monitoring system can confirm the driver's line of sight through the radar sensors installed on both sides of the rear of the vehicle Whether there is a vehicle in the blind spot and the driver's attention is indicated by the blinking LED on the exterior rear-view mirror; the lane keeping assist system and the lane departure warning system are activated at a speed of 64 km/h or more, and can be non-active in the vehicle (no turning signal is turned on When leaving the lane, vibrate the steering wheel and display prompt information on the instrument, and actively intervene before the vehicle leaves the lane, try to keep the vehicle track, reduce the possibility of traffic accidents;
Although consumers see the safety of a car, they may not understand the technology behind these high-tech safety models. However, it is not entirely OEMs that really promote the development of automotive active safety technology and provide technical support, but are first-class component suppliers such as Delphi, Bosch, and Continental. The pros and cons of active safety system performance depend to a large extent on the product performance of component suppliers, including cameras and radars. Delphi supports a wide range of high-quality products for all types of active safety systems.
Delphi's IFV-250 series smart front-view camera features high-performance optical features and a high dynamic range CMOS image sensor with a horizontal viewing range of 45° and a vertical viewing range of 29°. Can realize lane departure, forward collision warning, automatic headlight control, traffic sign recognition, pedestrian detection and other functions. 
The Delphi Collision Mitigation System (CMS) uses a unique data fusion algorithm to synthesize radar and camera input signals, which improves the functionality of the security system. The entire system includes a camera, a sophisticated vision control module, and a multi-mode electronically scanned radar ESR. When the vehicle equipped with the CMS is close to a pedestrian or other vehicle and there is a high risk of collision, the system will give the driver a warning. If the driver does not respond to the alarm, the system will automatically brake to avoid collisions or mitigate the damage caused by the collision. Applications that can be implemented in this system include: full-speed range adaptive cruise control, forward collision warning, lane departure warning, follow-up distance warning, and automatic braking. 
When the driver changes lanes or turns, the Delphi Side/Rear Radar Detection System (RSDS) alerts the driver to the approaching vehicle. When the vehicle behind the side enters the visual blind spot of the vehicle, the RSDS system will give the driver more reaction time by issuing an alarm, and these objects are generally difficult to see in the side mirrors. . Applications that can be implemented in this system include detecting the presence of targets in the blind side of the vehicle, changing lanes and assisting the line, and rear-end tracking. 
Delphi's smart parking aids use rear-view cameras and advanced algorithms to make parking simple. The parking assist system provides the driver with a more natural rear view image by calculating the reverse trajectory of the vehicle. When the driver selects the parking mode, the system assists the driver in selecting a suitable parking position by calculating whether the parking position is sufficient. The parking assistance system guides the driver during the driver's parking. When the driver continues the parking operation, the system assists the driver with a step-by-step voice prompt and a guideline superimposed on the vehicle display. 
Delphi also developed the industry's first system that integrates radar detection, camera detection, and data fusion functions into one precision module - RACam. Its achievable functions include full-speed range adaptive cruise control, lane departure warning/lane hold, vehicle distance warning, forward collision warning, collision mitigation, full-function automatic braking, pedestrian protection, higher performance target detection, automatic front Headlight control, traffic sign recognition. 
The 360° Intelligent Panoramic Parking Guidance System is a new member of Delphi's active security product family and made its debut at the Shanghai Auto Show last year. The research and development center led by Delphi (China) Technology Development Co., Ltd. provides a 360-degree panoramic view around the vehicle to assist with parking operations, making parking more secure, simpler, and more intuitive. 
Active safety will eventually become automatic driving when it comes to the end, and the safety of the car will reach the extreme at that time. The process of achieving the ultimate goal is long and arduous. This is also the direction of many traditional auto parts companies including Delphi. From the author's point of view, compared with the networking of vehicles that can be assembled by governments, car companies, and operators, laying the foundation is the hard truth. This foundation is active safety.
