What are the active and passive features?

Active safety refers to a vehicle's ability to prevent or reduce risks before an accident occurs through advanced technological systems. Its core lies in real-time monitoring of the driving environment and proactive intervention to enhance safety. Common active safety features include Anti-lock Braking System (ABS), Electronic Stability Control (ESC), Adaptive Cruise Control (ACC), Lane Keeping Assist (LKA), and Automatic Emergency Braking (AEB). These systems work together through sensors and algorithms—for example, ESC can automatically adjust torque distribution when the vehicle skids, while AEB can detect front collision risks and apply the brakes automatically. As technology advances, some high-end models now come with more sophisticated pre-collision systems or blind-spot monitoring, even integrating cameras and radar for 360-degree environmental awareness. It's worth noting that active safety complements passive safety (such as airbags); the former focuses on prevention, while the latter concentrates on protection after an accident. When choosing a car, consumers can pay attention to the actual performance of these features, but should be aware that different brands may use different names for the same systems. It’s advisable to test-drive to experience the responsiveness and reliability of the functions.

The core purpose of car safety configuration is to maximize the protection of passenger safety in the event of an accident, while reducing collision risks through preventive technologies. For example, anti lock braking systems can maintain steering control during sudden braking, and electronic stability programs can correct vehicle slippage. These active safety technologies have gradually become standard on mainstream car models. The passive protection system consists of airbags and pre tensioned seat belts, which reduce human impact in collisions, while the high-strength body structure resists deformation like a "cage". In recent years, intelligent safety technology has developed rapidly. Automatic emergency braking uses radar to monitor obstacles ahead, and lane keeping assistance can correct deviations. These systems achieve 360 degree protection through sensor networks. It is worth noting that the differences in safety configurations between different levels of car models are narrowing, and many economy cars are also equipped with 6 airbags and body stability systems. Consumers should pay attention to the Asean NCAP collision rating, as five-star rated car models usually have a more complete safety architecture. With technological advancements, future vehicles will integrate more driving assistance functions, but drivers are always the most critical link in the safety chain, and even the most advanced systems cannot completely replace cautious driving.

The safety systems of automobiles are mainly divided into two categories: active safety and passive safety. Active safety systems aim to prevent accidents, such as anti lock braking systems (ABS), electronic stability control systems (ESC), lane keeping assistance (LKA), and adaptive cruise control (ACC). These technologies actively intervene in driving operations by monitoring the vehicle's status or surrounding environment in real time to reduce risks. For example, ABS can prevent wheel lock during emergency braking, ESC can correct vehicle slippage, while LKA and ACC can help drivers maintain lane and distance, especially suitable for long-distance driving or traffic congestion. Passive safety systems are designed to protect passengers after an accident, including airbags, pre tensioned seat belts, high-strength body structures, etc. Their function is to reduce the damage caused by collisions. For example, airbags can quickly inflate at the moment of impact, buffering the collision between passengers and hard objects inside the car, while the body structure disperses the impact force through energy absorption design. Modern cars typically combine these two types of systems, such as some models automatically tightening their seat belts and applying the brakes when they detect an imminent collision. This collaborative design can more comprehensively ensure safety. With the advancement of technology, some high-end car models have also introduced more advanced systems such as blind spot monitoring and automatic emergency braking, further improving the level of driving safety.

Active safety features are the technological systems in a vehicle designed to prevent accidents during driving, using electronic systems or mechanical designs. Think things like Anti-lock Braking System (ABS), Electronic Stability Control (ESC), Lane Keeping Assist (LKA), and Automatic Emergency Braking (AEB). These systems constantly monitor the vehicle's status and its surroundings, then actively intervene in vehicle control to reduce human error or sudden risks. As technology has advanced, many models now also come with features like Adaptive Cruise Control (ACC) and Blind Spot Detection (BSD), which use radar or camera data to further enhance driving safety. It's worth noting that different brands might name similar features differently, but the core principles are similar. When shopping, consumers should look at actual test results rather than just relying on marketing terms. Additionally, active safety features usually need to work together with passive safety equipment like airbags to form a complete protection system. It's advisable to regularly check the system status to ensure they're working properly.

Passive safety features are technologies designed to reduce occupant injuries during a collision through pre-engineered structures or devices that activate automatically without any manual input. Common passive safety components include high-strength body structures, airbags, pre-tensioning seatbelts, and collapsible steering columns. The high-strength body absorbs and distributes impact forces through crumple zones, while airbags cushion the impact between occupants and hard interior surfaces. In recent years, premium models have added knee airbags, rear side airbags, and even external pedestrian airbags to further enhance safety levels. It's important to note that passive safety complements active safety systems like ABS and ESP – which help prevent accidents – and together they provide comprehensive protection. When shopping for a car, beyond just counting airbags, pay close attention to body steel strength ratings and crash test results, as body rigidity forms the foundation of passive safety. Additionally, child safety seat anchor points are also part of passive safety; proper use can reduce a child's injury risk by over 70%.
