Road transportation in hilly regions poses significant safety challenges due to steep gradients, sharp curves, and varying road conditions. Conventional braking systems rely heavily on driver response, which may be insufficient in critical situations, leading to accidents such as vehicle rollback or loss of control during descent. This paper presents a Safety Auto Brake System (SABS) based on a Micro-Electro-Mechanical System (MEMS) sensor for real-time slope detection and automatic braking control. The MEMS sensor, acting as an accelerometer, continuously measures tilt and acceleration along multiple axes and transmits data to a microcontroller for processing. Based on predefined threshold values, the system automatically activates the braking mechanism under unsafe conditions. The proposed system effectively prevents rollback during uphill starts and controls vehicle speed during downhill motion, thereby enhancing stability and safety. The integration of MEMS technology offers advantages such as high sensitivity, fast response, compact size, and low power consumption. Additionally, the system reduces driver workload and can be implemented using cost-effective components, making it suitable for both new vehicles and retrofitting applications. Experimental analysis indicates that the proposed system significantly improves vehicle control and reduces accident risks in hilly terrain. Future work may include integration with advanced driver assistance systems and adaptive control techniques for improved performance.
