DEVELOPMENT OF AN ELECTRO- MECHANICAL SP'EED LIMITING DEVICE FOR AUTOMOBILES

Abstract

Ovcrspccding has become a problem to our motorists because they want to reach their destination on time. forgetting that it is better to be late than be the late, This, project discusses the solution to the problem of overspeeding by developing an electromechanical speed-limiting device for automobiles. using Toyota and Peugeot cars as case studies, A simple. portable and cheap electro- mechanical device was designed and constructed, It was installed under the throttle pedal to reduce throttle valve opening. the quantity of fuel supplied into the combustion chamber a;HJ finally reduce the speed of the vehicle, The performance evaluation carried out showed that when the driver wanted to exceed the speed of IOOkm/hr. the circuit closed and a very loud alarm sounded and it was stopped when the speed returned to IOOkm/hr. Data analysis shows that the height of the device is inversely proportional to the speed of the vehicle and also that the percentage change in speed when ascending and descending a slope diminishes as the speed of the vehicle increases, Also. the statistical correlation between the height of much. Mechanical device and the speed was 98%,
