Accident prevention has been one of the leading areas of research today. Our paper is designed to prevent accidents due to loss of control, drunken driving, and rash driving, using circuitry aided by a microcontroller kit. In our work, braking distance and the distance of the obstacle are taken into consideration along with the speed of the vehicle. The sensor helps in finding the speed of movement of the vehicle and the ultrasonic sensor senses the distance of the object in front. These sensors provide real- time inputs to the microcontroller program. Using sensor the system will sense the speed of the vehicle and with the microcontroller, it will calculate the distance required to bring the vehicle to a complete stop for that speed. Breaking motors is incorporated to activate the brakes thereby achieving automatic breaking procedures. The system helps in conjunction with the driver judgment if the driver doesn’t sense the obstacle and applies the brake at the right time then the microcontroller initiates braking motor to apply the brakes automatically. Our future work deals with incorporating real time brake shoe wear system to provide enhanced feature for the intelligent braking system. By looking at safety in terms of avoiding accidents in the first place – and then protecting occupants when a crash is unavoidable – we can prevent more accidents, save more lives, and reduce insurance and medical costs to society. Intelligent Braking System approach represents a significant shift from the traditional approach to safety, but it is fundamental to achieving the substantial benefits.
The Braking System is the most critical system on your vehicle. Its maintenance and proper functioning are vital to you, your family and other motorists. You should not attempt to effectuate maintenance or repair work on brakes. Servicing or repairing the braking system requires specific tools and adequate technical training. That is exactly what Auto tech Performance offers you.
How does the Braking System work
The brake pedal, on which you apply pressure to slow down or stop your vehicle, is connected by levers and rods to the brake booster. The brake booster multiplies and transfers the leverage force produced by stepping on the brake pedal to the master cylinder. In turn, the master cylinder uses that amplified leverage to pressure the brake fluid from its reservoir through hydraulic lines toward the two front and rear brakes that are mounted on the wheels of the vehicle.
The hydraulic pressure that reaches each wheel’s brake is then used to create friction to slow down and stop the vehicle: the harder you push on the pedal, the more pressure is applied to the brakes, eventually locking the wheels – that is if your vehicle if not equipped with an Anti lock Braking System (ABS).
More precisely, in conventional braking system (without ABS), the brake fluid goes out to the wheels through proportional valves that distribute pressure according to weight distribution on each wheel.
Note that brake fluid has a slippery oily feel and no smell when new. As it ages, the fluid turns smoky brown from the water and contaminants that collect in the system.
Factors considered in designing the system are:
Distance of obstacle in front
With the proposed framework these sorts of mischances can be turned away. Utilizing a HALL sensor the framework will sense the rate of the vehicle and with the microcontroller, it will compute the braking separation: that is the separation required to convey the vehicle to a complete stop for that speed. Utilizing an Optical sensor, the framework will sense any moving or stationary hindrance in front and ceaselessly monitor its separation. At the point when the driver sees a deterrent in front and backs off there is no issue. Then again, in the event that he doesn’t have any significant bearing brakes and continue the same velocity, he goes to a point where the separation of the impediment equivalents to braking separation. This is the last risk for the driver to apply the brake and back off the vehicle. In the event that regardless he goes at the same speed, the microcontroller in the framework will actuate the brakes and evade an impact by conveying the vehicle to astop. Regularly, one would not stop at a moment that the vehicle is touching the impediment. Some separation is left before the snag. The separation is additionally accounted by the microcontroller. Assume for 50 km/hr if the braking separation is say 12.28 m, then 0.5 m is included and the braking separation is computed as 12.78m.
WIRELESS REMOTE CIRCUIT
It allows the driver to maintain directional stability and control over steering during braking.
Safe and effective
Automatically changes the brake fluid pressure at each wheel to maintain optimum brake performance.
ABS absorbs the unwanted turbulence shock waves and modulates the pulses thus permitting the wheel to continue turning under maximum braking pressure.
Less time and more profit.
We can use this system as safety purpose.
Highly accurate system for automatic braking system.
Less operating force is required
The system is working efficiently in both modes forward and reverse direction. When the sensor senses any obstacle behind and in front of the vehicle, it sends signals to the control unit which allows the vehicle to stop the running wheel. Thus we have an “intelligent braking system” which helps in understanding how to achieve low cost automation.
