BSM system (Blind Spot Monitoring) is the abbreviation of Vehicle Blind Spot Monitoring System. When a potential collision risk is detected, it alerts the driver via warning lights on the rearview mirror or audible alarms, effectively reducing safety hazards during lane changes. This system is becoming increasingly prevalent in high-end and some mid-range models in the Malaysian market, and is particularly suitable for local multi-lane highways and complex urban road conditions. Its technical implementation typically relies on 24GHz or 77GHz millimeter-wave radar, featuring strong anti-interference capability and an extended detection range (approximately 3-5 meters). Some models integrate with the Lane Keeping Assist System to automatically intervene in steering control when the driver disregards warnings and persists in changing lanes. The system's performance may be compromised during extreme weather conditions such as heavy rainfall, and drivers must maintain standard observation practices. As Malaysian consumers' demand for active safety features grows, the BSM system is transitioning from an optional feature to a standard configuration in mainstream vehicle models.
