Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
160 words
An accident reporting system for a land vehicle for calling a rescue automatically, comprising: shock sensor for detecting a shock exerted to a vehicle body; an air bag controller which outputs an instruction to unfold an air bag when the magnitude of the shock detected by said shock sensor exceeds a first predetermined value: an emergency level determining means which determines that a first emergency occurs when said instruction to unfold said air bag from said air bag control means is outputted, and which determines that a second emergency occurs when the degree of the shock detected by said shock sensor after receiving said instruction to unfold said air bag exceeds a second predetermined value; and an emergency sending means which transmits a first emergency information with radio wave when said emergency level determining means determines that said first emergency occurs, and which transmits a second emergency information when said emergency level determining means determines that said second emergency occurs.
Claim 2
Dependent Claim
160 words
An accident reporting system for a land vehicle for calling a rescue automatically, comprising: shock sensor for detecting a shock exerted to a vehicle body; an air bag controller which outputs an instruction to unfold an air bag when the magnitude of the shock detected by said shock sensor exceeds a first predetermined value: an emergency level determining means which determines that a first emergency occurs when said instruction to unfold said air bag from said air bag control means is outputted, and which determines that a second emergency occurs when the degree of the shock detected by said shock sensor after receiving said instruction to unfold said air bag exceeds a second predetermined value; and an emergency sending means which transmits a first emergency information with radio wave when said emergency level determining means determines that said first emergency occurs, and which transmits a second emergency information when said emergency level determining means determines that said second emergency occurs.
Claim 3
Dependent Claim
42 words
An accident reporting system for a land vehicle described in claim 1, wherein said first emergency information includes an information indicating a first impact in the accident and said second emergency information includes an information indicating a second impact in the accident.
Claim 4
Dependent Claim
20 words
An accident reporting system for a land vehicle described in claim 1, wherein said shock sensor includes an acceleration sensor.
Claim 5
Dependent Claim
55 words
An accident reporting system for a land vehicle described in claim 3, wherein when an instantaneous value of acceleration detected by said acceleration sensor exceeds a specified value, time integration of the acceleration starts, and the result obtained by integrating the acceleration for a predetermined time length is taken as said magnitude of the shock.
Claim 6
Dependent Claim
239 words
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.
Claim 7
Dependent Claim
239 words
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.
Claim 8
Dependent Claim
38 words
An accident reporting system for a land vehicle described in claim 5, wherein said first emergency information includes an information indicating a single impact accident and said second emergency information includes an information indicating a multiple impact accident.
