Brief Analysis of Active Braking Technology

[Introduction] In recent years, more and more intelligent configurations have appeared in cars on the market, and some consumers' car purchasing demands are no longer simply satisfied with space and fuel consumption. They have gradually shifted their attention to high-tech configurations, and active braking, as one of them, has also received more and more attention from consumers in the past two years. So today, the editor will briefly talk to you about active braking.

1. Active safety and passive safety

First, let’s talk about the car’s active safety and passive safety configuration.

Passive safety can be understood as the configuration of the vehicle that will play a role in an accident, such as the energy absorption device on the front of the vehicle, the airbags, seat belts and other rigid structures in the vehicle. Passive safety configuration is usually the last line of defense to protect us in critical moments, so here the editor also reminds everyone to fasten the seat belt when driving to ensure their own travel safety.

Active safety configuration, as the name implies, can be understood as configuration used to prevent vehicle collisions, such as active braking, collision warning, traction control system and other electronic stability programs. Now with the development of technology, more and more cars are equipped with active safety configurations, and the active safety configurations on the car will also be regarded as a major indicator of the overall safety of the vehicle and will be reviewed by major institutions.

2. How active braking works

Active braking is based on the optical radar/millimeter wave radar installed on the front of the vehicle, which monitors the driving status and road conditions of the vehicle in front in real time. If the radar detects that the vehicle in front brakes suddenly or there is an obstacle in the middle of the road, the radar transmits the signal to the vehicle ECU, which then sends a command to the brake pedal to produce a braking effect.

We all know that the driver's energy is limited. In critical moments, the driver often cannot react in time, and this is when the role of active braking comes into play. As a technology that major automakers have been continuously developing and updating in recent years, the active braking system is becoming more and more mature and practical.

3. Is active braking reliable?

The answer to this question is no.

Although the working principles of active braking systems of various car companies are different, there are large differences in the calibration methods. It is understood that Lexus' active braking will only sound an alarm and brake in an emergency.

Not all active braking can stop the vehicle. As an auxiliary system, active braking cannot completely replace the driver's braking. Active braking can indeed effectively prevent accidents to a certain extent, but to date, there is no data or report stating that active braking can work properly in all situations.

4. Editor’s suggestions

In general, active braking is not practical in daily driving, and the reason is very simple: electronic systems cannot see the world like human eyes, and cannot predict what is about to happen. The working method of active braking is quite different from the way we brake our vehicles in daily driving. If we use it for a long time, we will feel dizzy. Therefore, the editor recommends that you must concentrate on driving and not rely too much on this technology.

【Summarize】

Active braking can indeed prevent accidents, and with the continuous development of technology, I believe that the response sensitivity and other aspects of active braking will definitely get better and better. I also hope that consumers will regard active braking as a very important safety configuration when buying a car. At the same time, I also advise everyone: Having this configuration does not mean that we can relax when driving. We should also start with ourselves, fasten our seat belts, concentrate on driving, and prevent accidents from happening at the source to ensure our travel safety.
