Alternative Emergency Braking System for Vehicles

The main aim of this project is to develop an alternative emergency braking system and brake failure identifier for vehicles. In this proposed method, an eddy current braking is used for alternative emergency braking system and the brake failure is identified by placing the ultrasonic sensor opposite to brake pads of the vehicles, that detects the thickness of the brake pad and notifies the driver with a visual and audible alert if there is a tear or brake pads are detached. The performance of the alternative emergency braking system is evaluated with different tests the first test is using aluminium and copper disk; and second test is of different magnets that is neodymium and ferrite magnet. The time taken for the speed of the motor to reduce the speed is up to 65% in 5 seconds using the aluminium disk and neodymium magnet. However, the speed reduction of the motor is only 50% in 5 seconds of time using the copper disk and ferrite magnet. Overall, the system proved to be very accurate in terms of braking efficiency and braking force generated by the eddy currents when the aluminium disk and neodymium magnet is used.
