Abstract

An airbag deployment system is disclosed. The airbag deployment system comprises: a sensor module disposed at a passenger seat, for sensing the weight of an occupant in the form of an analog signal and converting the same into a digital signal to output the digital signal; and an airbag control unit for controlling the deployment of an airbag by analyzing the digital signal outputted from the sensor module and comparing the same with a preset value. Accordingly, the manufacturing cost of the product can be reduced, and the reliability of the product can be improved.

Claims

1. An airbag deployment system, comprising:

a sensor module disposed at a passenger seat, for sensing a weight of an occupant in a form of an analog signal and converting the same into a digital signal to output the digital signal; and

an airbag control unit for controlling deployment of the airbag by analyzing the digital signal outputted from the sensor module and by comparing the same with a preset value.

2. The airbag deployment system of claim 1, wherein the sensor module comprises:

a plurality of sensors disposed at the passenger seat, for sensing the weight of the occupant and outputting the analog signal; and

a converter/transmitter for converting the analog signal outputted from the sensors into the digital signal and outputting the digital signal.

3. The airbag deployment system of claim 2, wherein the digital signal outputted from the converter/transmitter of the sensor module is transmitted to the ACU by using any one of Manchester communication and DSI communication

4. The airbag deployment system of claim 2, wherein the airbag control unit comprises a digital receiver for receiving the digital signal outputted from the converter/transmitter.

5. The airbag deployment system of claim 4, wherein the digital receiver is a multi-type digital receiver which receives a signal outputted from a shock sensor and a signal outputted from a pedestrian sensor for sensing a walking state of a pedestrian for pedestrian protection as well as receiving the digital signal outputted from the sensor module.

6. The airbag deployment system of claim 2, wherein the sensor module further comprises an amplifier for amplifying the analog signal.

7. The airbag deployment system of claim 2, wherein the sensors are disposed at two positions of the passenger seat, spaced apart from each other.

8. The airbag deployment system of claim 2, wherein the sensors are disposed at four corners of the passenger seat.
