The GSM / GPS Module communication and the distance Sensor, checking the car’s distance from the

As the height of the ramp increased so did the acceleration of the car. This shows a positive trend. When the ramp was 10 cm high, between 0 and 30 cm, the car accelerated at an average rate of 17.7 cm/s2. When the ramp was 15 cm high, between 0 and 30 cm the car accelerated at a rate of 37 cm/s2. At 10 cm high, between 30 and 60 cm the car accelerated at a rate of 4.2 cm/s2 .

Frequency of the signal measures the number of cycle of the signal repeated in unit time.

In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.

Transmission Time= [(100 bit/t seconds) = (10,000,000 bits / 1 second)] Therefore, t = 10 ms

means by the fourth unit it will take 80% of the time of the second and the eighth unit will take

that the distance covered by the dot in one second will change significantly from second to

SYS-002 The system shall able capable of detecting a vehicle travelling with high beams at a distance of 170 feet and send a warning signal on the control panel of vehicle.

If the obstacle is in the range of the sensor , the obstacle is detected .When the system detects obstacles, the speed of the vehicle is reduced to zero and an image alert is displayed in the smartphone along with voice output, which means that the detection is successful. If there is no obstacle ahead, there is no outcome. If the obstacle is out of the range of the sensor , there is no outcome and the detection fails.

Near the top of the ramp, the car’s speed was around 102 centimeters per second. In the middle of the ramp, the car’s speed was around 156 centimeters per second and near the end of the ramp, the car’s speed was around 196 centimeters per second. No one in the group pushed the car at any time. The slope of the ramp was also constant the entire time. There had to be an explanation for why the car’s speed was faster as the car went on. What we came up with was that as the car traveled down the ramp, it picked up speed. Once we plotted these points on the graph, it was extremely evident that this was in fact what had happened. The graph clearly showed that the speed of the car was increasing as it went down the

For this speed analysis, I used Limpert’s analysis of a rotating vehicle. I utilized the sine value of the angle determined by the path of travel of Vehicle 1 versus the angle of approach at measured distances during the rotation. In conjunction with the standard speed loss equation, the sine value is applied to the coefficient of friction value. The result based on this analysis is a speed loss range of 22.85 mph to 29.50 miles per hour during

The assistant records the distance between the bottom of the ruler (the zero-centimetre mark) and the top of the thumb where the ruler has been caught in metres.

Many of us are familiar only with the traditional lock which is used to secure our automotive vehicles, there are wide range of locks which operate in different ways that have been developed over the years by the locksmith industries, and the newly and highly computerized keys that are highly secure are transponder keys. Car theft is one of the most prevalent crimes today but thanks to transponder keys, the incidence of car theft has dramatically reduced. Transponder car keys can help prevent your car from being stolen.

Most of the car companies are even worried about tracking about their vehicles. So, they want it to get installed such devices in their vehicles too.

Abstract-This paper presents review on the accident detection techniques and some future possibilities in this field. Now-a-days lots of accidents happen on highways due to increase in traffic and also due to rash driving of the drivers. And in many situations the family members or the ambulance and police authority is not informed in time. This result in delaying the help reached to the person suffered due to accident.Road accidents constitute the major part of the accident .The purpose of the project is to find the vehicle where it is and locate the vehicle by means of sending a message using a system which is placed inside of vehicle system Most of the times we may not be able to find accident location because we don’t know where accident will happen. Our project Real Time Vehicle Tracking and Accident Detection with GPS is designed to avoid such situations.

Now-a-days, it became very difficult to know that an accident has occurred and to locate the position where it has happened. It’s very difficult for the lives of victims until anyone noticed and informed it to the ambulance or to any hospital and if it occurs in remote areas there will be no hope to survive. To overcome these, GSM and GPS technologies are used. The GPS based vehicle accident identification module contains a vibrating sensor and a GPS modem connected to the microcontroller. When an accident occurs, the vibration sensor gives the signal to the microcontroller, which sends the information to the LCD display through GSM network. The vehicle is tracked for every five minutes using GPS
