FABRICATION OF AUTOMATIC BRAKING SYSTEM USING ULTRASONIC SENSOR

IRJET, 2023

According to data from the Ministry of Transport, 426 people are killed in traffic accidents each year, with 18 occurring every hour in our country. The majority of accidents occur as a result of poor infrastructure, a lack of road protocols, the near absence of measures to enforce traffic laws, and the driver's failure to hit the brakes. Vehicle speed control can play a critical role in reducing the number of accidents, which an automatic system can achieve. The braking system is an intelligent mechatronic system that includes an Ultrasonic wave emitter on the front portion of a car that produces and emits Ultrasonic waves. An Ultrasonic receiver is also installed on the front of the vehicle to receive a reflective Ultrasonic wave. The reflected wave (detected pulse) gives the distance between the obstacle and the vehicle. Then a microcontroller is used to control the speed of the vehicle based on the detection pulse information to push the brake pedal and apply brake to the car stupendously for safety purpose.

Automatic Braking System using Ultrasonic wave

International Journal for Research in Applied Science & Engineering Technology (IJRASET), 2022

An automatic Braking system is an intelligent mechatronic system includes an Ultrasonic wave emitter provided on the front portion of a car producing and emitting Ultrasonic waves. An Ultrasonic receiver is also placed on the front portion of the car operatively receiving a reflective Ultrasonic wave signal. The reflected wave (detected pulse) gives the distance between the obstacle and the vehicle. Then a microcontroller is used to control the speed of the vehicle based on the detection pulse information to push the brake pedal and apply brake to the car stupendously for safety purpose. Automotive vehicles are increasingly being equipped with collision avoidance and warning systems for predicting the potential collision with an external object, such as another vehicle or a pedestrian. Upon detecting a potential collision, such systems typically initiate an action to avoid the collision and/or provide a warning to the vehicle operator. The aim is to design and develop a control system based on an automatic, intelligent and electronically controlled automotive braking system for automobiles is called as "Sensor based Electromagnetic Braking System". This Braking system consists of IR transmitter and receiver circuit and the vehicle. The IR sensor is used to detect the obstacle. There is any obstacle in the path, the IR sensor senses the obstacle and giving the control signal to the microcontroller, which in turn sends a signal to the motor to stop and also to the Electromagnet so as to stop the vehicle as programmed. This project facilitates electromagnetic braking system using solenoid. Here in fabrication module include a vehicle prototype frame associated with a dc motor and a electromagnet.

Distance measurement using Ultrasonic sensors

Cars and vehicles have been incorporated into culture as one of the most resourceful, easiest and accessible means of transportation available. But besides being a suitable and common means, it is equally an incredibly dangerous mode of transport. Thousands of people die in vehicle accidents each year, whether it is accident with another vehicle or with a motionless object. A method of early accident exposure and evasion can control several accidents that may be associated to factors such as loss of control, careless driving, tired/intoxicated drivers, and not paying concentration to the road. As the current market does not present a normal safety feature in any car, the use of sensory tools to sense potentially hazardous objects a definite distance away and either slows the car down or shove to a safer path has not been released. In this research paper a new technique is introduced for safety against accidents. Eight ultrasonic sensors are used to sense different types of objects. By implementing a possible improvement in safety/sanctuary systems in vehicles, the vehicle and sensor would be able to operate normally until the sensor detects possible risk. In our project, the sensor does not give output or signal until the car comes within ~75 feet of an object, at which timer sends information of hurdle to driver. The sensor only indicates the presence of an object; it is up to the user or driver to tackle the hurdle.

An ultrasonic sensor distance induced automatic braking automobile collision avoidance system

2017 IEEE 3rd International Conference on Electro-Technology for National Development (NIGERCON)

Collisions in automobiles have become a major safety concern; cases of damage and death due to automobile collisions are frequently reported. The number of pedestrians knocked to death by automobiles is also on the rise in cities and highways. Further into the game reserves, wild animals are also frequently knocked to death by automobiles. The cost of a life cannot be estimated, the cost of damages to the automobiles also impacts negatively on investment. In most cases drivers fail to notice the presence of obstacles ahead and brakes need a driver's response to operate thus increasing the response time, hence reducing their reliability. Many approaches to automobile crash avoidance systems have been proposed in recent time, however, such approaches mainly concentrate on steering maneuvering control. In addition, these approaches do not take into consideration the safety distance to stoppage of the automobile, more so, many approaches only provide a warning signal to the driver for activating the automatic braking. This always provides a room for human error. This paper presents the development of an automatic microcontroller based crash avoidance system that employs obstacle detection and distance measurement using ultrasonic sensors to detect obstacles and their distances. Once the obstacle has been detected and safe separation distance is reached, the automobile performs safety distance induced braking at that distance to bring the automobile to a stoppage. From the results obtained after tests, the system has an average response time of 0.86s to the activation of the brakes and a 12.8 percentage error with respect to the obstacle real distance.

Sonar Technology Assisted Vehicle Sensor

International Journal of Recent Technology and Engineering (IJRTE), 2019

In the Philippines, more than half of its vehicular accidents are caused by motorcycles, and most of the reasons why these accidents are happening is because of distracted driving, lowered road awareness, delayed response to emergency such as accidents, and over speeding to name a few as confirmed by World Health Organization’s reports. Premised on this idea, the researchers decided to design, develop, and test a device that would provide a solution to this. Thus, the title “Sonar Technology Assisted Vehicle Sensor” was created. The device was completed after three months of research and development in Eastern Samar State University Salcedo Campus. Results of the four-stage test: the Benchmark; Alpha; Beta; and Usability tests indicated that the Sonar Technology Assisted Vehicle Sensor is fully functional and can detect vehicles approaching and can produce corresponding alarms, and can now be implemented. As an additional feature, the device has been imbedded with a Global Positioni...

Intelligent Mechatronic Braking System

Currently, vehicles are often equipped with active safety systems to reduce the risk of accidents, many of which occur in the urban environments. The most popular include Antilock Braking Systems (ABS), Traction Control and Stability Control. All these systems employ different types of sensors to constantly monitor the conditions of the vehicle, and respond in an emergency situation. In this paper the use of ultrasonic sensors in safety systems for controlling the speed of a vehicle is proposed. An intelligent mechatronic system includes an ultrasonic wave emitter provided on the front portion of a car producing and emitting ultrasonic waves frontward in a predetermined distance. An ultrasonic receiver is also placed on the front portion of the car operatively receiving a reflective ultrasonic wave signal. The reflected wave (detected pulse) gives the distance between the obstacle and the vehicle. Then a microcontroller is used to control the speed of the vehicle based on the detection pulse information to push the brake pedal and apply brake to the car stupendously for safety purpose.

Development Of Sonar Sensor System For AutonomousUnderwater Vehicles (AUV) Application

2010

This project is about the development of sonar sensor system in purpose for Autonomous Underwater Vehicles (AUV) application. The concept of this project is using the ultrasonic sensor as a main device to transmit and receive the signal from the obstacle. The ultrasonic sensor will be combined to the ultrasonic circuit. Usually, the ultrasonic sensor is often used in robots for obstacle avoidance, map building and especially in navigation. Ultrasonic range sensor is works by emitting a short burst of 40 kHz sound. In addition, a small amount of sound energy is reflected by objects in front the device and returned to the detector or the receiver. The receiver sends this reflected signal known as echoes to the microcontroller to determine how far away the objects. However, to know how far away the objects it is using the speed of sound and time it took for the signal to be reflected. Unfortunately, echoes are not completely a product of distance. Different the medium will give the different speed and different result. It uses a Proowave Ultrasonic TXR and MikroC software as a compiler.

Accident Prevention System Using Ultrasonic Sound Sensors

Road accidents often happen when vehicles come very close and the drivers sleep or not aware of the vehicles coming close. This may happen while in traffic or when driving with high speed and cross each other on road. This paper presents a method using ultrasonic sound sensor technology that will recognize and display messages about the vehicles that approach the vehicle on all four sides within two meters range and alert the driver. Thus while the driver is alerted about the vehicles that come very close in his vicinity, accidents can be better avoided.

IRJET-Analysis of Obstacle Detection Using Ultrasonic Sensor

Automation of the car braking system is an important feature in the development of the smart car. The ability of a smart car to detect and classify an obstruction that is in varying proximities from it play a vital role in the system’s design. In this study, EV3 Lego Mindstorm equipped with an ultrasonic sensor was used as a model of a large scale vehicle. EV3 Lego MIndstorm was programmed to slow down when it is at a certain distance from the obstruction, and to stop when it is 15 cm away from the obstruction. There were five obstructions: wood, paper, cloth, plastic and metal. The distance measurement of the ultrasonic sensor and the Neural Network was used for the classification of the obstruction and Multiple Correlation was used for obstacle detection. There were 250 samples taken from the distance measurements of five different types of obstruction, each with a different cross sectional area, and a total recording time of 8 seconds. Overall, there is a high correlation coefficient in the distance measurement of the different types of obstruction materials. It is concluded that the ultrasonic sensor was able to detect the five given types of obstruction. Classification performance was very poor, which means that on the basis of distance measurement, the ultrasonic sensor cannot effectively classify the types of obstructions.
