Fabrication of an Automated Collison Avoidance System using Ultrasonic Sensor
Vehicle accidents are ubiquitous in recent years. This is because of heavy increase in population of vehicles, due to its high demand. They pose a serious threat to life and property. A system must be designed to minimize the effects of these accidents. The aim of the present study is to design a device which can successfully scan the surroundings during driving and apply brake to avoid front end collision of the vehicle, along with extension of bumper. Ultrasonic sensor provided on the front end of the vehicle detects the presence of the obstacle. The data from the sensor is an input to the microcontroller. Microcontroller 8051 decodes the logic and generates appropriate control signals for the activation of driver alert mechanism, along with automatic actuation of pneumatic braking circuit and pneumatic bumper circuit. Pneumatic braking circuit applies brake and bring the vehicle to halt, and the latter one provides the safety of vehicle during impact. Driver alert mechanism is included to alert the driver at a safe braking distance from collision. All of these are integrated in a single system to provide for maximum protection of passenger, vehicle and property.
