Is the Active Braking System Useful in High-Speed Danger Situations?
2 Answers
Active braking systems are not useful in high-speed danger situations. Below are additional details: 1. Reasons: In terms of speed, the current models on the market equipped with active braking systems are designed for urban use, functioning effectively at speeds below 80 km/h, which is a dynamic speed. At a static speed of 80 km/h, it is practically difficult for the system to be effective. Automakers, considering cost, generally equip vehicles with factory-installed active braking systems using microwave radar. The detection range of microwave radar is about 10 meters, which means it cannot guarantee effectiveness at high speeds. In contrast, laser radar has a detection range of about 150 meters and higher accuracy, making it particularly effective on high-speed roads with high risk factors. However, the cost of laser radar is more than five times that of microwave radar. 2. Active Safety Systems: Active safety systems refer to safety systems that include electronic devices such as ABS and ESP. Passive safety systems involve vehicle body energy-absorbing structures, seat belts, airbags, etc. Among active safety systems, the most typical is the active braking system.
The active braking system is absolutely useful in high-speed emergencies, as someone who frequently drives long distances, I have deep personal experience with this. On the highway, speeds are high and reaction times are short, but having the system assist is literally a lifesaver. I remember last year on the highway, I was overtaking when the car in front suddenly braked hard. Before I could react, the system instantly intervened and stopped the car, preventing a rear-end collision. It uses cameras and sensors to monitor the road ahead in real-time, and when it detects a collision risk, it automatically applies the brakes to reduce speed or even stop the vehicle. Of course, when speeds exceed 130 km/h, braking distances increase and the system response might be slightly slower, but in most cases it can reduce serious accidents to minor scrapes. For daily driving, keeping the system clean is crucial—don’t let dirty lenses affect detection. Overall, it provides immense peace of mind for high-speed driving.
