The core function of the Automatic Emergency Braking (AEB) system is to monitor obstacles ahead of the vehicle in real time through sensors and actively trigger braking to avoid or mitigate collisions when the driver fails to respond promptly. When the system determines a high collision risk and the driver has not taken braking action, it will first issue visual or auditory warnings. If there is still no response, it will automatically apply partial or full braking. In the Malaysian market, mainstream models like the Proton X70 and Toyota Corolla Cross already come standard with AEB. Their operational range typically covers speeds between 30-80 km/h, with pedestrian detection capability generally effective below 60 km/h. AEB does not entirely replace manual driving, and its performance is influenced by weather conditions, visibility, and target object characteristics. For instance, heavy rainfall may impair the detection accuracy of millimeter-wave radar. According to test data from the Malaysian Institute of Road Safety Research (MIROS), vehicles equipped with AEB can reduce rear-end collision incidence by 38%. However, drivers must remain vigilant as the system has limitations in detecting sudden lane-cutting vehicles or complex traffic scenarios.
