Vehicle Speed Control and Accident Avoidance System Based on Arm M4 Microprocessor

Now a day's road accident is one of the major concerns in our country. Reckless vehicle driving is the major reason behind those road accidents. Alarming rate of accidents and uncontrollable car in the road demand an automatic system that would guide drivers immediate in dangerous situation. When any obstacle (like human body, vehicle, and other object) comes in front of the vehicle, speed control of the vehicle is the viable solution to avoid accident. We propose a solution in our project to avoid road accidents and to control speed of vehicles. Front Ultra-sonic sensors of the vehicles detect obstacles, then Cortex ARM M4 process the information and passes signals to the wiper motor to brake the vehicle with the help of Arduino Uno. Furthermore, if any obstacle from the backside come closer to vehicles, immediately a buzzer will alert the driver.
