THE INTELLIGENT CAR WITH ACCIDENT ALERT AND DRIVER ASSISTANCE SYSTEM

Abstract: Road accidents Road accidents continue to be a major cause of injuries and fatalities worldwide due to driver negligence, poor visibility, and delayed obstacle detection. Traditional vehicle safety systems mainly focus on minimizing accident impact rather than preventing collisions. This paper presents an IoT Based Intelligent Car with Driver Assistance System, an intelligent and cost-effective solution developed using the ESP32 microcontroller, HC-SR04 ultrasonic sensor, SG90 servo motor, L298N motor driver, and the built-in Bluetooth of the ESP32. The ultrasonic sensor continuously scans the surroundings by rotating through the servo motor to detect nearby obstacles. Based on the measured distance, the ESP32 controls the vehicle to avoid collisions automatically. Users can also operate the vehicle manually through Bluetooth using a smartphone application. Experimental testing demonstrated reliable obstacle detection, smooth Bluetooth communication, and efficient autonomous navigation. The proposed system is affordable, portable, and suitable for educational, research, and intelligent transportation applications. By integrating embedded systems with IoT technology, the system enhances driver safety and contributes to the development of smart transportation.
