Implementación de un simulador de Airbag para colisiones frontales para la escuela de Ingeniería Automotriz.

Abstract

Among the passive safety systems of a vehicle seat belt and airbag reduce 50% the likelihood of injuries to the occupants of a car in a traffic accident, the airbag is activated at speeds above 30 km/h, and it is deployed at a speed of 300km/h with an inflamed volume varying between 30 and 60 liters. For the design of the simulator prototype airbag module control, as well as the selection of electronic control elements according to the simulation needs, the performance of the airbag system is studied for a scheduled simulator, using an electronic card Arduino AtMega 2560 Additional software was developed in LabVIEW programming environment, so that students can relate theory to practice. It also has elements of booster group, which is a fundamental part of the bank, because without it could not be performed bag inflation for demonstration. The simulation will run when the parameters are entered, such as speed and force of impact is suitable incidence angle, otherwise the system will not deploy the airbag. The tests that can be performed in the bank are checking voltages impact sensor simulator, generate fault codes to disable the sensor and identify codes and reading data in the software where the user can interact. It has a manual operation and maintenance to perform the labs, so it is recommended handled with discretion.
