VEHICLE CONTROL BY SOFTWARE TO OVERCOME ACCIDENT

OBJECTIVES

1.To design and fabricate a vehicle control circuit.
2.To develop an algorithm to control the vehicle.

METHODOLOGY

1.The host vehicle repeatedly radiating infrared waves in a predetermined range and senses the obstacle with IR sensors.
2.Sensors transmit digital signals to microcontroller.
Microcontroller then decides the movement of the vehicle and signals to the dc motor controller (L298) to control the motors.
3.Two motors are used. One motor at the back position which gives the vehicle forward or backward motion. Another motor is at the front to control the steering to give rotational motion.
4.Programming is done with MikroC compilier.
5.PIC 16F72 microcontroller is used.

OUTPUT
1.When obstacle is in the front, the vehicle stops down with brake and then turns to left.
2.When obstacle is in the right position, the vehicle turns to left.
3.When obstacle is in the left position, the vehicle turns to right.
