Abstract:
A collision judging system comprising:a sensor unit including: an acceleration sensor for detecting acceleration; a data conversion section for converting the acceleration, detected by said acceleration sensor, into an acceleration data set including a check code; and a transmission section for transmitting the acceleration data set converted by said data conversion section; a received data control unit including: a reception section for receiving the acceleration data set transmitted from said transmission section of said sensor unit; an error determination section for determining, with reference to the check code included in the acceleration data set, whether the acceleration data set has been received properly from said transmission section via said reception section, and outputting the received acceleration data set as a proper data set when it is determined that the acceleration data set has been received properly but as an erroneous data set when it is determined that the acceleration data set has not been received properly; and a first storage section for storing a plurality of the acceleration data sets output by said error determination section; and a collision judgment control unit for making a collision judgment on the basis of a latest proper data set of the plurality of the acceleration data sets stored in said first storage section.
