1. Is the car collision avoidance system a scam?
Automobile anti-collision system is a new type of intelligent control technology for automobiles, which can effectively prevent car accidents in times of crisis. However, there are many brands in this system, and the prices are mixed. It is difficult to choose a suitable and effective brand, so many people think it is a scam.
Second, how to choose a high-quality car collision avoidance system?
First: self-driving experience.
The so-called intelligence is embodied in active braking. There are two kinds of braking: flexible braking and emergency braking. For example, on a city road, when you stop to walk, braking flexibly is just like driving. According to the speed of the vehicle in front, gently brake and slow down to stop. The intelligent anti-collision system of road guards is completely humanized braking, and inferior products brake urgently when they are 5- 10 meters away from the front car, which has poor experience and is easy to cause accidents in the rear car; In addition, it can better reflect the advantages and disadvantages of high-speed intelligent collision avoidance. Many inferior products can't start at the speed above 60/h, and the system stability is poor (sometimes obstacles in front can be detected, and sometimes they can't be controlled), while the active braking system of roadside cars can start collision avoidance normally at high speed or low speed.
Second: beware of fake and shoddy goods.
The trial run is good, but the final product is unusable. Why? The sample car is made of other products, but it sells fakes.
Third, some companies attract consumers at low prices.
Some companies sell at very low prices, only a few thousand dollars, so whether their products can be used is a question mark. For example, if we only look at the ranging and speed measuring sensors, the quality of ranging lidar depends on the pulse frequency emitted by the radar. The higher the frequency, the higher the ranging accuracy. However, high-performance lidar requires cutting-edge technology and is expensive. Without independent intellectual property rights, the automobile intelligent anti-collision system of the special radar for vehicle ranging and speed measurement cannot pass customs clearance, which is very important for information collection. Low-tech radar ranging and velocity measurement technology is one of the keys that middle and high speed intelligent collision avoidance can't prevent. Radar of similar products on the market can only measure distance, but not speed. One of the main reasons is that collisions over 60 kilometers are inevitable. Our road guards can play their anti-collision function stably at the speed of 5 to 140 km. Our infrared lidar system can measure not only the distance, but also the speed of other objects at the same time. We are ranging and speed measuring sensors, and our performance far exceeds that of laser rangefinder. Active collision avoidance at medium and high speed has practical value. The cost of this sensor alone is about 3000 yuan.
Fourth: look at patents.
Most of the company's patents are forged or the applied patent name is "side attack", which has little to do with the active anti-collision of automobiles, and the road protector is the only invention patent of the "active anti-collision device of automobiles". You can check the authenticity in the patent office.
