Decoding 8 active safety systems on cars
(Baonghean.vn) - Nowadays, more and more features are equipped on each car to help reduce the risk of accidents and injuries. However, not all car users are familiar with the safety systems... Below are some active safety systems that are built into many car models. The way manufacturers name each feature may be different, but the way it operates is generally similar.
1. Cruise Control
 |
| This feature is equipped in most C-class cars and above. With this system, the driver can relax when driving on the highway, thanks to the speed control through the buttons on the steering wheel. At that time, the right foot can leave the accelerator and place it on the brake pedal to be ready to handle all situations on the road... When driving on the highway and highway, keeping an eye on the speed limit will distract the driver. With the Cruise Control system, the driver can set a maximum speed limit, and focus on the situations on the road without worrying about going over the speed limit. |
2. Autonomous Emergency Braking (AEB)
 |
| It is a feature that can detect and prevent a rear-end accident or reduce the speed of the collision, thanks to radar, laser or surveillance camera sensors. When encountering an emergency situation, the system will warn the driver with sound, image or steering wheel vibration. If there is no response from the driver, the car will automatically brake to avoid a collision... This system is basically divided into 3 types, with different conditions of use such as warning systems at low speeds, high speeds and pedestrians. Each system will operate at a different speed, but it is also possible to combine all 3 types depending on the manufacturer. |
3. Lane Departure Warning (LDW)
 |
| Lane departure warning systems use the vehicle's built-in cameras to monitor lane markings at certain speeds. If the vehicle departs from its lane without signaling, an audible, visual, or vibration alert is triggered. Some systems use vibration motors built into the steering wheel to simulate the feeling of the vehicle crossing a lane marking on the highway to trigger the driver's reflexes. |
4. Lane Keep Assist (LKA)
 |
| Lane Keeping Assist (LKA) systems directly intervene to minimize or avoid lane drift. While LKA systems typically only steer when the vehicle is about to drift out of its lane, many manufacturers add a feature that keeps the vehicle centered in its lane... Drivers need to understand the limitations of LKA systems; they rely on cameras to detect lane markings, so if the markings are blurred, the system will be ineffective or not work. LKA systems also cannot handle dangerous curves or construction zones. Therefore, the driver's attention and vigilance is always required. |
5. Forward Collision Warning (FCW)
 |
| Forward Collision Warning (FCW) is one of the basic driver assistance features on today's cars, helping to warn the driver when a collision is about to happen. This system only warns in advance but does not perform any tasks to minimize the collision... The signaling method is also different for each car model and car manufacturer, but most of them use sound warnings, light signals on the instrument cluster, warnings via HUD screen, or seat and steering wheel vibration. |
6. Electronic stability control (ESC)
 |
| In case the driver turns the steering wheel too quickly to avoid obstacles, or turns at high speed on slippery roads, causing the car to lose control and slide to both sides, ESC will act on the braking system to help readjust the steering direction, and automatically reduce engine power to help the driver regain control of the car... ESC not only works when the car is operating on wet or icy roads, but also works well when the car accelerates or turns. The core element is that ESC helps detect the risk of wheel slip before it becomes a real threat. |
7. Active Parking Assist System
 |
| The automatic parking assistance system will help the driver complete parking faster without having to touch the steering wheel. Some car models also support the driver to take the car out of the parking spot, limiting collisions and accidents when parking... When the activation button is pressed, the system will automatically detect an empty space through sensors and notify the driver, then the driver only needs to shift gears and brake according to the car's command; and the calculation of optimal and fastest steering will be controlled completely automatically. |
8. Blind Spot Warning System
 |
| It operates based on sensors located on the side or back of the vehicle. These sensors will emit electromagnetic waves when the vehicle is moving, thereby detecting other vehicles in blind spots that the driver cannot observe through the mirror. Then send signals to the controller and warn the driver in many forms such as emitting sounds, warning lights on the rearview mirror... |
