As commercial vehicles play an increasingly important role in modern logistics and transportation, the development and application of onboard safety systems have become more critical. Commercial vehicle safety systems are mainly divided into active safety systems and passive safety systems. This article will explore these two types of safety systems in detail and their roles in enhancing vehicle safety and reducing traffic accidents.



Active Safety Systems

Active safety systems refer to measures taken proactively to prevent accidents before they occur. The goal of these systems is to reduce or avoid traffic accidents through early warnings, automatic interventions, and other means. Here are some common active safety systems:

1. Forward Collision Warning System (FCW)

The Forward Collision Warning System uses sensors such as radar and cameras to monitor the road conditions ahead in real-time. When the system detects a potential collision risk in front, it issues warnings through visual, auditory, or tactile signals, alerting the driver to take necessary braking or steering actions.



2. Adaptive Cruise Control System (ACC)

The Adaptive Cruise Control System can automatically adjust the vehicle’s speed based on the speed of the vehicle ahead to maintain a safe following distance. When the vehicle in front slows down, the system automatically decelerates; when the road ahead is clear, the system returns to the set cruising speed, providing greater safety and comfort during long-distance driving.

3. Lane Departure Warning System (LDW)

The Lane Departure Warning System monitors the vehicle’s trajectory using onboard cameras. When the vehicle deviates from its lane, the system warns the driver through sound or vibration to prevent lane departure accidents caused by fatigue or distraction.



4. Blind Spot Detection System (BSD)

The Blind Spot Detection System uses radar or cameras installed on the sides and rear of the vehicle to monitor blind spots in real-time. When a vehicle enters the blind spot, the system issues a warning, alerting the driver to potential risks in the blind spot, effectively preventing side collision accidents.

Passive Safety Systems

Passive safety systems aim to minimize injuries to occupants and pedestrians after an accident occurs. These systems mainly improve the vehicle’s safety performance in collisions through structural design, material selection, and restraint systems. Here are some common passive safety systems:

1. Seatbelts and Pretensioners

Seatbelts are one of the most basic and effective passive safety systems. In a collision, seatbelts secure occupants in their seats, preventing them from being thrown out due to inertia and reducing the risk of secondary collisions. Pretensioners tighten the seatbelts at the moment of impact, further reducing the occupant’s forward movement.



2. Airbags

Airbags inflate rapidly during a collision, forming a soft cushion that absorbs the occupant’s impact energy, reducing the risk of head and chest injuries. Modern commercial vehicles are typically equipped with front airbags, side airbags, and curtain airbags for comprehensive protection.

3. Vehicle Structure Design

Modern commercial vehicles widely use energy-absorbing materials and structural optimization techniques in their design to enhance the vehicle’s collision energy absorption capacity. For example, the front and side of the vehicle are designed with crumple zones that absorb energy through deformation during a collision, reducing the impact force on the passenger compartment.



4. Child Safety Seat Anchors

To protect child passengers, many commercial vehicles are equipped with child safety seat anchors (such as the ISOFIX system), ensuring that child seats can be securely installed on the vehicle seats, enhancing the safety of child occupants in a collision.
