Car, one of the greatest inventions of mankind. Since the invention of the first car by Carl Benz in 1886, humans have continually improved it, and in the process, "safety" has gradually become one of the most important vehicle performance engineers value. In the past, the speed of the car was slow, and even if the collision occurred, it would not cause major losses. With the advancement of the car powertrain technology, the car is getting faster and faster, and the accident rate is also rising, which makes people pay attention to the car. safety. Engineers began to thicken the steel plate and strengthen the strength of the material. This is the passive safety technology we will talk about later. Later, the speed of the car was further increased and the number of cars was increasing. The passive safety technology itself could not guarantee the safety of the car. It coincided with the vigorous development of automotive electronics technology, and the active safety technology based on it came into being.

Active safety technology is a technology that helps drivers to mitigate/avoid accidents when they cannot avoid accidents. It is an area that every major car supplier and component supplier attaches great importance to. It has become more and more developed after years of development. The more advanced it is, the more commonly referred to it as the Advanced Driver Assistance System (ADAS). For example, in the past, when the car deviated from the lane, the active safety system could only serve as a warning. Now, the system has evolved into a lane keeping system that helps the car stay in its original lane. Through this article, the author conducts an inventory of the most advanced active security technologies.
Volvo Cars has always been known for its safety, and its collision-mitigation system in the V40 offers a variety of safety features such as adaptive cruise control, vehicle front-collision alarms with pedestrian and vehicle automatic braking, pre-crash induction detection, Lane keeping assist, automatic headlight control and traffic light recognition. In addition, regarding the safety of the rear and side of the car, the V40 uses a rear and side detection system to enable blind spot detection, lane change assistance, and intersection alarms.
In 2013, Volvo introduced a pedestrian/cyclist collision detection system with automatic braking. This system not only detects pedestrians and cyclists in front, but also alerts drivers and can take the initiative if the driver does not respond. brake. AOL Autos, a well-known foreign automotive media, named this technology one of the best technologies of the year. The system uses a radar to estimate the velocity of the object in front and works with the fast camera to estimate the contour and size of the object in front. Both of them continuously monitor the motion 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. The new Mondeo is equipped with a range of leading-edge active safety technologies in its class. The ACC Intelligent Adaptive Cruise System on the new Mondeo automatically adjusts the speed. When there is no car on the current side, the set speed will be maintained; when there is a car on the current side, the intelligent adaptive cruise system will automatically adjust the speed and maintain the set distance from the preceding vehicle. The intelligent adaptive cruise system adopts microwave radar, which has good real-time performance and large detection angle range. It can improve fatigue efficiency while improving fuel efficiency, and is very practical for users to drive on conventional highways.
In addition, the active parking assist system installed in the new Mondeo can help the owner to park easily and greatly improve the convenience of the owner. The blind zone monitoring system can confirm the driver's sight through the radar sensors placed on the two sides of the rear of the vehicle. Whether there is a vehicle in the blind area and the driver blinks through the LED flashing on the exterior mirror; the lane keeping assist system and the lane departure warning system are activated at a speed of 64 km/h or more, and the vehicle can be inactive (the turn signal is not turned on) When leaving the lane, vibrate the steering wheel and display a message on the meter, and actively intervene before the vehicle leaves the lane, try to keep the vehicle's trajectory and reduce the possibility of traffic accidents.
Although consumers are seeing the safety of a car, they may not understand the technology behind these high-tech safety models. However, the real promotion of automotive active safety technology and technical support is not entirely a complete vehicle manufacturer, but a first-tier component supplier such as Delphi, Bosch and China. The performance of active safety systems depends to a large extent on the product performance of component suppliers, including cameras and radars. Delphi supports a full range of high quality products for all types of active safety systems.
Delphi's IFV-250 Series Smart Forward Cameras feature high-performance optical performance and a high dynamic range CMOS image sensor with a horizontal viewing range of 45° and a vertical viewing range of 29°. It 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 the radar and camera input signals, which enhances the functionality of the security system. The entire system includes a camera, a precision vision control module, and a multi-mode electronically scanned radar ESR. The CMS-equipped vehicle warns the driver when it is close to pedestrians or other vehicles and has a high risk of collision. If the driver does not respond to the alarm, the system will automatically brake to avoid collision or mitigate the damage caused by the collision. The achievable applications of the system include: adaptive cruise control at full speed range, forward collision warning, lane departure warning, following distance warning, and automatic braking.
The Delphi Side/Rear Radar Detection System (RSDS) alerts the driver to the approaching vehicle as the driver changes lanes or turns. When there is a vehicle entering the visual blind zone of the vehicle behind the side, the RSDS system will give the driver more reaction time by issuing an alarm. In general, these objects are difficult to see in the side mirrors. . The achievable applications of the system include: detecting the presence of targets in the blind side of the vehicle, lane change and line assist, and rear rear end warning.
Delphi's intelligent parking assist system uses rear view cameras and advanced algorithms to make parking easy. The parking assist system provides the driver with a more natural rear view of the vehicle by calculating the vehicle's reverse trajectory. When the driver selects the parking mode, the system helps the driver select the appropriate parking position by calculating whether the parking position is sufficient. The parking assist 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 guide line superimposed on the vehicle display.
Delphi has also developed the industry's first system to integrate radar detection, camera detection and data fusion into a precision module - RACam. Its achievable functions include adaptive cruise control at full speed range, lane departure warning/lane hold, 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° Smart Panoramic Parking Guidance System is a new addition to the Delphi Active Safety product family and made its debut at the Shanghai Auto Show last year. Developed by Delphi (China) Technology R&D Center, it provides a 360° panoramic view around the vehicle to assist with parking operations, making parking safer, simpler and more intuitive.
Active safety will eventually become autonomous driving, and the safety of the car will reach its limit at that time. The process of achieving the ultimate goal is long and arduous, and this is the direction of many traditional auto parts dealers, including Delphi. In my opinion, it is the last word to lay a good foundation for the car network that can be built by the government, car companies, and operators. This foundation is active security.
