Development of a Vehicle Door Anti-Collision System with Pressure and Radar Sensors for Enhanced Road Safety

Abstract

To address the issue of door-opening collisions, this paper proposes a door-opening anti-collision system that incorporates a door-opening pressure transducer and a vehicle-mounted radar sensor as its primary components. The system evaluates the potential for collisions by integrating data from both in-vehicle occupants and external vehicles. Utilizing voice alerts, radar video displays, and an automatic locking mechanism, it provides warnings and protective measures in hazardous situations. The vehicle's CPU processes this information, considering the braking conditions, door switch sensor, and the time it takes for an approaching vehicle to reach the current vehicle at its speed, to determine the necessity of an alarm. This system effectively safeguards pedestrians and reduces the risk of injury and property damage caused by door-related accidents.
