Automatic Hydraulic Bumper and Speed Limiting System

The loss of human as well as financial loss due to repaired of the damaged vehicles is alarming. In recent years the numbers of vehicles have increased drastically leading to further increase in accidents and repair costs. Automobile manufacturing companies are developing upgraded vehicles in respect of technology and fuel efficiency. Manufactures are also continuously working on improvement of safety measures in modern vehicles. Present work involves design and simulation of “Automatic hydraulic bumper and speed control system� to enhance safety measures. This system consists of IR transmitter, receiver circuit, control unit and hydraulic bumper system. As and when vehicle is close to obstacle the IR transmitted signal from the vehicle is reflected back from obstacle and received by detector and processed in the control unit. The control unit activates the breaking system. Simultaneously the solenoid valve is activated to move the bumper forward. In case of collision from front side impact force on the vehicle gets absorbed which prevents any unexpected extent of damage or injury during the accident. The bumper system has been designed to satisfy the safety norms ECE 26 using CATIA V5 software.
