Authors: Sunil Kovalam, Harihara Sudhan, Praveen Bansode and Sanjay Gaddamwar Mahindra & Mahindra Ltd Abstract: In the emerging markets especially like India and other similar countries, growing traffic density on the roads leading to different kind of accident types including head on collision, rear end collision, side impact collision and accidents involving with pedestrians or cyclists or two wheelers etc. These accidents could be due to over-speeding, distracted driving and inadequate road infrastructure. Providing necessary safety restraints system (Airbags and Seat belts) and its robust functionality in different real world accident scenarios will be a challenging to vehicle manufactures. It is a high time to redefine the traditional crash sensing architecture strategies with logical approach based on the thorough study of available accidents data, kind of objects, scenarios leading to severe accidents. Out of which Car to Truck Under-ride accidents and Rear-end collision cases are increasing day by day and ineffective sensing of collision forces and inadequate functionality of safety restraint system are leading to sever injuries or fatalities. It is imperative to improvise the crash sensing system architecture and place the crash sensors inventively at optimal locations in the vehicle for early detection of collision forces and for robust functionality of safety restraint system to mitigate the injuries and fatal cases to the maximum extent with innovative approach. This technical paper describes the thought process, methodology for improving the robustness of functionality of safety restraint system in afore mentioned critical Under-ride and Rear-ending accident scenarios and this innovative crash sensing system architecture can be introduced in vehicles to cater the needs of robust functionality of safety restraint system (Airbags and Seat belts) in real world accident scenarios to protect the vehicle users with improvisation in existing situations while ensuring of fuel cut-off in case of ICE & high voltage cut-off in case of EV vehicles.
