What are the common active safety devices in cars?

Seat belts, airbags, ABS (Anti-lock Braking System), ESP (Electronic Stability Program), etc., are all common active safety devices inside vehicles that can activate when the vehicle is close to losing control. Seat belts: Known as the 'life belt,' it is an extremely effective safety protection device. During a collision or emergency braking, the seat belt firmly secures the driver and passengers in their seats, preventing them from hitting the windshield or being thrown out of the vehicle. Airbags: In the event of a collision, airbags rapidly deploy to prevent the occupants from hitting the steering wheel or window glass. ABS (Anti-lock Braking System): It automatically prevents wheel lock-up during emergency braking, ensuring that the vehicle's direction can still be adjusted. ESP (Electronic Stability Program): It helps prevent the vehicle from skidding in emergency situations.
I've always found active safety features incredibly practical while driving. For example, the Anti-lock Braking System (ABS) prevents wheel lock-up during emergency braking to avoid loss of control; Electronic Stability Program (ESP) helps stabilize the car during turns or on icy roads to prevent rollovers; Traction Control System (TCS) prevents wheel spin during acceleration and improves grip on slippery surfaces; Adaptive Cruise Control (ACC) automatically adjusts speed to maintain distance from the vehicle ahead on highways, reducing fatigue; Lane Keeping Assist (LKA) makes minor steering adjustments when distracted to prevent drifting; Automatic Emergency Braking (AEB) uses radar to detect vehicles ahead and automatically applies the brakes to avoid collisions. These aren't just gimmicks—they've saved me several times in daily driving, especially during rain, fog, or heavy highway traffic, greatly enhancing my sense of security. When buying a car, I always check for these features.
I am fascinated by automotive technology, where active safety devices intervene in driving in real-time through electronic systems. ABS monitors wheel speed and adjusts braking pressure during lock-up to maintain steering force; ESP uses gyroscopes to detect skidding and controls braking power to prevent rollover; TCS reduces torque based on wheel speed sensors to avoid slipping during acceleration; blind spot monitoring warns of vehicles in the side rear to prevent lane-changing accidents; forward collision warning uses cameras to remind drivers to maintain a safe distance. These devices work together to make driving more controllable, such as when ESP automatically corrects during slippery curve steering, reducing the risk of human error.
