Dynamic Safety Monitoring and Active Safety Enhancement for a Lightweight Energy-Efficient Electric Vehicle

Pemantauan Keselamatan Dinamis dan Peningkatan Keselamatan Aktif pada Kendaraan Listrik Hemat Energi Berbobot Ringan

Abstract

Energy efficient electric vehicles are generally designed with lightweight structures and minimal system architectures to optimize power efficiency; however, the integration of embedded active safety systems remains limited. This study proposes an embedded dynamic safety monitoring framework based on multi-sensor integration to enhance the active safety capability of a lightweight prototype electric vehicle. The system integrates an accelerometer–gyroscope module and a vibration sensor within a microcontroller-based architecture to perform three-axis acceleration data acquisition and real-time dynamic condition analysis using a threshold-based classification algorithm.

Unlike conventional accident detection approaches that focus on post-event response, the proposed system is designed as an active safety enhancement mechanism through continuous monitoring of vehicle dynamic behavior. The implementation was carried out on the Jayandaru EV prototype developed by the IMEI Team. Experimental results indicate that the dual-verification configuration improves detection reliability and minimizes misclassification caused by transient vibration fluctuations.
