A car with active braking function is actually divided into three or six.

Today, I would like to share with you how much the difference between the active brakes of expensive models and the active brakes of cost-effective models. What is the technology of active braking of various brands? What is the impact on driving, learning and learning along with Xiaobian.

The mainstream solution for active braking technology, generally speaking, the technology used by everyone is a millimeter-wave radar in the front of the vehicle, and then there is a camera inside the rearview mirror, through which the two devices cooperate with each other. Achieve the perception and detection of dangerous road conditions ahead. Thereby the vehicle effectively implements the role of active braking.

In addition, you will find that all models with millimeter wave radar on the front, like Volvo, Audi, and Honda Accord, always have a black one in the front of the car. This is the millimeter wave radar. But this millimeter wave radar is actually very expensive to manufacture. If there is an accidental damage, the radar will cost at least 10,000 yuan. So in order to skip the high cost of radar. Nissan is proposing a solution that is ingenious.

Together with the National Aeronautics and Space Administration of the United States, they jointly developed an ultra-high-speed visual recognition system based on such top technology companies. The name sounds very sloppy, but in fact it is just the principle of recognition through the camera inside the rearview mirror. In fact, it is exactly the same as the face recognition technology in the mobile phone or camera, but the face recognition is replaced. The identification of various road conditions and the identification of various dangerous situations, in this way, its cost is greatly reduced.

From the official data information, the name of the active brake equipped with this technology is called FEB, which is the pre-crash warning system. Models like New Sylphy and Bluebird are equipped with this system. The range of speeds that it can adapt to is still quite good, from ten kilometers to eighty kilometers can work. However, Xiaobian is most concerned about the most concerned. It uses the camera to analyze and identify the rain and snow weather. This kind of camera is obviously affected by the environment at night, and whether it can achieve effective recognition is not mentioned. Therefore, this ultra-high-speed visual recognition system is really useful, and it needs to be tested before it can be known.

Another model that does not use the millimeter-wave radar solution is the Ford model. Their technology is called the ACS low-speed safe driving system. The 7 is actually the same as Volvo's urban safety system. They are making the inside mirror more. Complex and costly laser sensor. Take the latest version of Fox, the system can start up below 50 km/h, and the original Fox system is under 30 km/h. In addition, the system officially only claims that it can identify obstacles in front of the vehicle and avoid rear-end collisions, but there is no clear rule on whether to recognize pedestrians.

Another manufacturer uses a very traditional solution, that is, Honda's CMBA, also known as collision mitigation braking system, is the standard millimeter wave radar, plus the solution of the interior rearview camera system. In fact, the system itself is still very advantageous. It has a very strong pedestrian recognition function. At a speed of 20 kilometers per hour or so, it can avoid collisions by completely autonomous braking. To feel this set of CMBS systems, it is equally good to identify and avoid dangerous situations.

Therefore, Xiao Bian believes that Honda's traditional solution is more mature and more reliable in terms of the active braking technology of so many cost-effective models. Let's take a look at the performance of high-end brands. The first thing to say is the new generation of Mercedes-Benz E-Class. This car represents the highest level of Mercedes-Benz in terms of high-tech active safety. Pedestrian behavior recognition can only be regarded as the initial level. The function of the vehicle, like the identification of stationary objects, crossing the intersection of vehicles and pedestrians is not a problem. It can be said that the danger of all front directions of the vehicle can be effectively identified and resolved.

As for the enhanced urban safety system represented by Volvo's new XC90, the system claims to be able to function at any speed, and the special objects like children and bicycles can be well recognized and at night. The same can work very well, its identification of various dangerous targets in this enhanced urban security system can be said to be flawless and quite accurate.

Mercedes-Benz, Volvo, this high-tech active safety identification system I have designed for you, in fact, has reached a very high degree of intelligence, it can be said that it is a good paving for the future of autonomous driving. This is currently the highest level of active brakes, behind which are high-cost stereo cameras and more expensive millimeter-wave radars, so the cost constraints make this technology difficult to achieve in a cost-effective model in the short term.

From the large number of cases in life, as long as the active brake function works effectively under 30 kilometers per hour, almost 70% of the rear-end accidents will be avoided, not to mention the popularity of smartphones. When driving, consciously and unconsciously look at the mobile phone, because of the traffic danger caused by this distraction is controlled. But don't forget that active braking is definitely not the best solution to avoid rear-end collisions, because even if you can avoid the rear-end collision, don't forget the rear car, it is possible to catch up. Moreover, active braking at high speed is not the best way to solve the rear-end collision.

The focus of this issue is that the active brakes of most expensive models are able to accurately identify the pedestrians in front of the vehicle and avoid dangerous occurrences. The cost-effective models of most cost-effective models cannot accurately identify the pedestrians in front of the vehicles. There is still a certain gap in the technology of active braking of various brands. It is also protective for drivers and pedestrians. But no matter how good technology at any time, it can't replace people's concentration and concentration of driving.
