The invention provides a safety airbag controller comprising a first ultrasonic sensor, a second ultrasonic sensor, a third ultrasonic sensor, an A/D (analog/digital) converter and a control device. The first ultrasonic sensor is disposed on a console in front of a driver and is used for detecting the position of the driver and outputting a first position signal. The second ultrasonic sensor is disposed on a roof above the driver and is used for detecting height of the head of the driver and outputting a second position signal. The third ultrasonic sensor is disposed on the console arranged in front of a passenger seat and is used for detecting the position of a passenger seated in the passenger seat and outputting a third position signal. The A/D converter is connected to the first, second and third ultrasonic sensors and is used for converting analog signals output by the sensors, into digital signals. The control unit is connected to the output end of the A/D converter and outputs control signals to corresponding safety airbags according to the signals output by the sensors. The first, second and third safety airbags are started or closed according to the control signals.
