Active safety systems
Era of rapid development in science
and technology from the semiconductor era and the beginning of our lives to keep the change gradually. From simple computer networks now ubiquitous terminals, electronic systems. Meanwhile, back in the late 20th century, 70 the early 80s, when etching silicon wafers with a large etched membrane production structure and the back pressure sensor. The thin silicon diaphragm deformation under pressure, will affect the curve of the surface of the varistor, the change could pressure into electrical signals. Later, the circuit includes the capacitive sensing moving mass accelerometer, used to trigger automobile airbags and positioning gyroscopes. These technologies currently used in car navigation, car security. Vehicle safety for vehicles, active safety and passive safety is divided into two aspects.
Active safety: is to try to ease the manipulation of control car. Both braking and acceleration on a straight line or around the direction should be as smooth as possible to play, and will not deviate from the route set, and does not affect the driver's field of vision and comfort.
Passive safety: is the car after an accident on the protection of vehicle occupants, and now the concept of the protection extended to all the people inside and outside the car or object.
Active safety is absolutely the most critical automotive electronics R & D in the technical part, particularly in the design of automatic collision avoidance, the main body including the front / rear / side collision warning (FCW), panoramic imaging system monitoring (AVM), Drive deviation warning (LDW), reverse image recognition system (RVC), tire pressure monitoring system (TPMS), driver fatigue warning and so on.
But so many active safety systems, how do we choose? To make the right choice, first of all understand each other is necessary, but also "know ourselves and win every battle." Next, Xiaobian more practical to you on the current electronic systems, active safety features, but that many electronic systems can be installed after, we can according to their own driving habits and needs to be a choice. Of course, ESP, ABS and other vehicle control, active safety systems generally can not yet installed after that can only be modified to get.
First, the panoramic imaging system monitoring (AVM) and the reverse image recognition system (RVC)
Storage in dense cities is a relatively depressed parking thing, especially in the commercial center of the underground car park. Small space for parking is undoubtedly a challenge to owners, especially beginners. Sometimes inevitably be some small collision. After all vehicles at close range, there are many cases of visual dead ends.
Supporting traditional optical car sight:
At present, most cars still use the traditional auxiliary optical line of sight, but it is completely sufficient for the veteran. However, the low number of smaller objects or the child was easily ignored.
Original panoramic imaging system monitoring (AVM)
With the CCD camera technology and the increasing level of electronic systems, many automakers introduced by the four cameras to monitor a variety of road conditions around the vehicle, forming a kind of look down from the visual effects, panoramic imaging system monitoring (AVM).
Parking can be installed after the image recognition system (RVC)
Usually, when we drive, the distance between the front car is relatively easy to grasp familiar. But the rear of the car's visual blind spot is relatively large, often difficult to grasp the distance and road conditions, reversing the visual system is not installed on the car, it spent money to install a reverse image recognition system is more cost effective.
