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.

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.

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.

The braking system is applied on the vehicle to form driving safe using proper system design. Accident are occur on the road due to technical problem of system or mistake of driver. Sometimes driver lose control over vehicle and doing rash driving on roads. In most urban areas of the world especially in India accidents associated with transportation and automobiles cause an enormous number of fatalities. This can be comes up with poor infrastructure, lack of road protocols and almost nonexistence of measures to enforce laws of the road. On average, 1199 accidents take place every day in the country. The intelligent braking system plays the main role in reducing the number of accidents on roads and control the vehicle speed. This intelligent braking system has an ultrasonic sensor which detect the obstacles on road ,the reflected signal gets received by receiver which results in activation of braking circuit and brakes are applied.
Electro-hydraulic braking system for autonomous vehicles
International Journal of Automotive Technology, 2010
Reducing the number of traffic accidents is a declared target of most governments. Since dependence on driver reaction is the main cause of road accidents, it would be advisable to replace the human factor in some driving-related tasks with automated solutions. To automate a vehicle, it is necessary to control the actuators of a car, i.e., the steering wheel, accelerator, and brake. This paper presents the design and implementation of an electro-hydraulic braking system consisting of a pump and various valves, allowing the control computer to stop the car. It is assembled in conjunction with the original circuit for the sake of robustness and to permit the two systems to halt the car independently. This system was developed for installation in a commercial Citroën C3 Pluriel of the AUTOPIA program. Various tests were carried out to verify its correct operation, and an experiment showing the integration of the system into the longitudinal control of the car is described.

The most frequent cause of vehicle accidents (car, bike, truck, etc.) is the unexpected existence of barriers while driving. An automated braking system will assist and minimize such collisions and save the driver and other people’s lives and have a substantial influence on driver safety and comfort. An autonomous braking system is a complicated mechatronic system that incorporates a front-mounted ultrasonic wave emitter capable of creating and transmitting ultrasonic waves. In addition, a front-mounted ultrasonic receiver is attached to gather ultrasonic wave signals that are reflected. The distance between the impediment and the vehicle is determined by the reflected wave. Then, a microprocessor is utilized to control the vehicle’s speed depending on the detected pulse information, which pushes the brake pedal and applies the vehicle’s brakes extremely hard for safety. For work-energy at surprise condition for velocity 20 km/hr, the braking distance is 17.69 m, and for velocity 50...
