Abstract
In the present accident reporting system for a land vehicle, when an emergency such as a crash-accident occurs and a sudden deceleration is exerted to a body, an calculating section time-integrates the acceleration detected by an acceleration sensor, and outputs an instruction to unfold an air bag when the integrated value exceeds a specified value, and unfolds an air bag. In parallel with the unfolding of an air bag, an emergency level determining section judges at least a slight accident occurs if an instruction to unfold an air bag is outputted, and after that, monitors the integrated value of acceleration of the calculating section, and judges a multiple impact accident occurs when the integrated value of acceleration after the unfolding of an air bag exceeds a specified value. An emergency communication operating section automatically sends an emergency information corresponding to the result of the judgment of the emergency level determining section concerning slight-accident/serious-accident to an emergency center with radio wave.
