The design of minicar’s airbag control system
Abstract： Airbag is a passive safety device, it is a important part of.automotive occupant auxiliary protection system.

Airbag control system consists of sensors, controllers, gas generators and air sacs. When the car suffered a collision resulting in dramatic changes in the speed, the sensor will sense the collision signal to the ignition controller. Controller will identify the extent of the collision to determine whether the ignition signal is issued, once given the ignition signal, the generator will generate a large amount of gas of gas in a very short period of time, the airbag will expand rapidly and put a cushion between the driver and the vehicle component., so that the driver, passenger's head and chest filled with gas pressure in the airbag, the airbag use the damping effect to absorb the kinetic energy of the inertial force generated by the human body in order to reduce the degree of injury suffered. The design uses a intelligent control system with a microprocessor and data storage. Using MCU to calculate the measured signal from sensors, when the collision occurred and reaches a certain intensity, it will export the ignition pulse to detonate gas generator and produce large amounts of gas filled balloon rapidly. The airbag control system designed consists of a microprocessor, Hall circuit , accelerometer circuit, self-diagnosis alarm circuit, power supply circuit, reset circuit, serial communication circuit, and ignition control circuit etc. The overall picture of circuit theory will be presented by software of Altium.
