ABS (Anti-lock Braking System) and AEB (Autonomous Emergency Braking) are two automotive safety technologies with distinct functional orientations. The core function of ABS is to prevent wheels from locking up completely by modulating braking force at high frequency during emergency braking, maintaining tyre rotation to enhance directional control. For instance, it prevents loss of vehicle control on slippery roads during sudden braking, but the system only activates when the driver actively depresses the brake pedal. AEB, conversely, is an active safety system that employs sensors such as radars and cameras to monitor obstacles ahead in real time. When the system detects a collision risk and the driver fails to respond promptly, it automatically initiates emergency braking and can even achieve a complete stop. From an application perspective, ABS constitutes a passive safety technology that optimizes the braking process, whereas AEB actively prevents collisions, frequently interfacing with functions like adaptive cruise control, and serves as a fundamental component of autonomous driving technology. While both enhance driving safety, AEB demonstrates superior capabilities in accident prevention and automation. Currently, ABS is standard equipment, while AEB remains in the adoption phase due to higher costs.
