Abstract

A vehicle collision detection device includes a plurality of sensors for detecting at least one parameter selected from an acceleration that acts upon the vehicle body and a deformation induced in the vehicle body by the acceleration, and then wirelessly generating an output signal, and a controller for assessing collisions on the basis of the output signal received from the sensors. Each sensor includes a distinguished value memory part for storing a characteristic distinguished value for each of the sensors, a transmitter for transmitting the distinguished value together with the output signal to the controller, and a power generator for producing electric power by an external force and feeding the power to the transmitter.
