RSE is Restraint System Electronics. RSE involves Crash Sensing Algorithms for vehicles. These algorithms decide if the AIRBAGS have to be deployed or not depending on the severity of crash. The different crash sensing algorithms are developed for Front, Side, and Roll Over crashes. The simulation tool for the same is developed and it is tested with.
