This system consists of ultrasonic sensors, namely, ultrasonic wave emitter and ultrasonic wave receiver. The ultrasonic wave emitter is provided at the front of the car, producing and emitting ultrasonic waves at a predetermined distance in front of the car. An ultrasonic wave receiver is also provided in the front portion of the car, receiving the ultrasonic wave signal reflected from the obstacle. The reflected wave (detection pulse) is measured to obtain the distance between the vehicle and the obstacle. The PIC microcontroller is then used to control the servomotor based on detection pulse information, and the servomotor automatically controls the braking of the car. This work demonstrates the possible use of an accelerator pedal decoupling mechanism in this system, whereby the accelerator pedal automatically disengages once the braking is started. Therefore, even if the acceleration pedal is depressed the vehicle will not accelerate and this will avoid collision. This solves the safety problem in case the accelerator pedal is pressed when the vehicle is expected to brake.
Automotive vehicles are increasingly equipped with collision prevention and warning systems to predict possible collision with an external object such as another vehicle or a pedestrian. Upon detection of a potential collision, such systems typically initiate an action to avoid collision and / or provide a warning to the vehicle operator. The goal is to design and develop a control system based on an automated, intelligent and electronically controlled automotive braking system for cars, it is called "INTELLIGET BRAKING SYSTEM". This braking system consists of the transmitter and receiver circuit of the IR and the vehicle. The IR sensor is used to detect the obstacle. There is some obstacle in the path, the IR sensor detects the obstacle and gives the control signal to the microcontroller, which in turn sends a signal to the motor to stop and also to the solenoid to stop the vehicle as programmed.
