DESIGN AND ANALYSIS OF REGENERATIVE BRAKING SYSTEM AND AUTOMATIC BRAKING USING ULTRASONIC SENSOR

The main aim of this project is to generate electrical energy from vehicle braking system. A regenerative brake is an energy recovery mechanism which slows a vehicle by converting its kinetic energy into another form, which can be either used immediately or stored until needed. This contrasts with conventional braking systems, where the excess kinetic energy is converted to heat by friction in the brake linings and therefore wasted .The most common form of regenerative brake involves using an electric motor as an electric generator. In electric railways the generated electricity is fed back into the supply system, whereas in battery electric and hybrid electric vehicles, the energy is stored in a battery or bank of capacitors for later use. Energy may also be stored mechanically via pneumatics, hydraulics or the kinetic energy of a rotating flywheel. This rotation of flywheel is used to store the electrical energy to battery by using Permanent magnet D.C generator.
