Active safety enhanced braking system with driver condition monitoring for passenger vehicles

Accidents are the leading causes of injuries and fatality rate raises vulnerably in automobile. The need of additional safety options to reinforce the active safety in vehicles. The foremost reason behind the accident is drivers fault and braking inefficiency. Automatic braking and additional features are incorporated in high cost vehicles not in low cost vehicles. The research is carried on the low cost vehicles to prevent drivers from collisions which are cost effective. Therefore the result suggested that more than 16 to 20 percentage of collision occurs due to driver’s health issues. The drivers fault is monitored and braking efficiency is enhanced by using the proposed system. The proposed system used to monitor the condition of the driver by inserting sensor in steering wheel for pulse measuring. The mechanical plunger for actuating the braking system is incorporated to prevent the collision during health issues. During abnormal condition of the driver the pulse sensor gives the signal to the controller to activate the hydraulic plunger connected to the brake pedal. The actuator which is placed above the brake pedal and it is compressed when the signal from the controller to compress the brake pedal during demand. The proposed system analysis the condition of driver to enhance the protection to the driver and retards the vehicle speed to prevent the accidents.
