The autonomous car is the vehicle that is capable of sensing its environment and can navigate without any human input. In this vehicle we use GPS for navigation and the ultrasonic sensor to avoid collisions. Since it is autonomous, the threat of stealing the vehicle will be more. In order to keep it secure, the GSM and GPS modules are provided with key. If anyone tries to unlock the vehicle apart from the normal procedure, by using the GSM module the message will be sent to the owner of the vehicle. GPS is used to locate the exact latitude and the longitude position of the vehicle. If the owner replies back to the GSM module that the vehicle is in theft, the engine gets locked automatically. The Ultrasonic Sensor is used to detect the obstacles and also for the determination of the distance with high accuracy. So, the vehicle will be able to sense the fore coming vehicle or the obstacle and will get alert. In order to focus the headlights of the car in the direction of the turn, i.e. in the direction of wheels, the servo motors are used. The Servo Motors allows the control of the angle, velocity and the acceleration. The Servo Motors takes the angle of the wheel during the change of direction. By making use of that angle, the headlights will rotate along the direction of wheels. The solar panels are used to absorb the radiations that are emitted by the sun. These absorbed radiations are converted into Electrical Energy which is used to charge the batteries. An Arduino Port is used to interconnect all these equipment’s to work according to their applications in an effective manner. The directions of the vehicle in which it is moving and the detection of the obstacle will be displayed on the LCD. Finally, when the predefined path is reached, the alarm starts ringing to confirm that the destination has been reached.
