Accident reporting system for a land vehicle

An accident reporting system for a land vehicle, comprising:

• shock sensor in the longitudinal direction for detecting a shock in the back and forth direction of the vehicle exerted on a vehicle body;
• front air bag controller which outputs an instruction to unfold a front air bag when the degree of the shock detected by said shock sensor in the back and forth direction exceeds a first specified value;
• shock sensor in the transverse direction for detecting a shock in the transverse direction of the vehicle exerted on said vehicle body;
• a side air bag controller which outputs an instruction to unfold a side air bag when the degree of the shock detected by said shock sensor in the lateral direction exceeds a second specified value;
• an emergency level determining means which monitors said instruction to unfold a front air bag outputted from said front air bag controller and said instruction to unfold a side air bag outputted from said side air bag controller, determines that a first emergency occurs when either of the instructions is outputted, and determines that a second emergency occurs when both of the instructions are outputted;
• and
• an emergency sending means which sends a first emergency information to a specific destination by radio when said emergency level determining means determines that said first emergency occurs, and which sends a second emergency information when said emergency level determining means determines that said second emergency occurs.
