Abstract
Abstract A system for indicating an abnormal condition of an automobile in which the condition of inspection items relating to the driving of the automobile is detected, and running speed of the automobile is detected. The system decides that the condition of an inspection item has reached a first abnormal level, and upon detection of the stoppage of the automobile after the time point of the decision, a voice cautioning the driver of the abnormal condition of the inspection item is automatically generated. Upon detection of the fact that a second abnormal level higher than the first abnormal level has been reached, a voice warning the driver of the abnormal condition of the inspection item is generated regardless of the driving condition of the automobile.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
145 words
A method of indicating an abnormal condition of an automobile, comprising the steps of: monitoring inspection items relating to the driving of the automobile; deciding that the condition of an inspection item has reached a first abnormal condition; automatically generating a voice cautioning the driver of the abnormal condition of said inspection item when a parameter for determining the generation of a cautioning voice has reached a predetermined level of generation of the cautioning voice after the time point of said decision of the first abnormal level; deciding that the condition of said inspection item has reached a second abnormal level higher than said first abnormal level; and automatically generating a voice warning the driver of an abnormal condition of said inspection item regardless of the driving condition of said car at the time of said decision on the reaching of said second abnormal level.
Claim 2
Independent Claim
145 words
A method of indicating an abnormal condition of an automobile, comprising the steps of: monitoring inspection items relating to the driving of the automobile; deciding that the condition of an inspection item has reached a first abnormal condition; automatically generating a voice cautioning the driver of the abnormal condition of said inspection item when a parameter for determining the generation of a cautioning voice has reached a predetermined level of generation of the cautioning voice after the time point of said decision of the first abnormal level; deciding that the condition of said inspection item has reached a second abnormal level higher than said first abnormal level; and automatically generating a voice warning the driver of an abnormal condition of said inspection item regardless of the driving condition of said car at the time of said decision on the reaching of said second abnormal level.
Claim 3
Dependent Claim
85 words
A method for indicating an abnormal condition of an automobile according to claim 1, wherein said parameter for determining the generation of the cautioning voice is the speed of the automobile, and the voice cautioning the driver of the abnormal condition of said inspection item is automatically generated upon detection of the fact that, starting with the time point of said decision on the reaching of the first abnormal level, the driving of the automobile is stopped and the speed thereof is reduced to zero.
Claim 4
Dependent Claim
86 words
A method of indicating an abnormal condition of an automobile according to claim 1, wherein said parameter for determining the generation of the cautioning voice is a condition of a demand switch adapted for demanding the generation of a cautioning voice, and a voice cautioning the driver of an abnormal condition of said inspection item is automatically generated upon detection of the fact that, starting with the time point of said decision on the reaching of said first abnormal condition, said demand switch is turned on.
Claim 5
Dependent Claim
26 words
A method of indicating an abnormal condition of an automobile according to claim 1, wherein said warning voice is generated while visually displaying said warning simultaneously.
Claim 6
Dependent Claim
32 words
A method of indicating an abnormal condition of an automobile according to claim 1, 2, 3 or 4, wherein said inspection item is the temperature of the cooling water for the engine.
Claim 7
Dependent Claim
28 words
A method of indicating an abnormal condition of an automobile according to claim 1, wherein said inspection item is the air pressure of the tires of the automobile.
Claim 8
Dependent Claim
24 words
A method of indicating an abnormal condition of an automobile according to claim 1, wherein said voice is synthesized by a digital voice synthesizer.
Claim 9
Dependent Claim
26 words
A method of indicating an abnormal condition of an automobile according to claim 1, wherein the voice generation is capable of being stopped by manual operation.
Claim 10
Independent Claim
193 words
A system for indicating an abnormal condition of an automobile, comprising: detector means for detecting the condition of an inspection item relating to the driving of the automobile and producing a detection signal; sensor for detecting the level of said parameter for determining the generation of a cautioning voice and producing a signal corresponding to the level of said parameter; operational processing means for producing a first abnormality signal when deciding that said detection signal from said detector means has reached a first abnormal level and that said signal from said sensor has reached a predetermined level for issuing a caution signal, said operational processing means producing a second abnormality signal regardless of the condition of the signal of said sensor when deciding that said detection signal from said detector means has reached a second abnormality level; and voice generator means for generating a voice cautioning the driver of the abnormal condition of said inspection item in response to a first abnormality signal from said operational processing means, said voice generator means generating a voice warning the driver of the abnormal condition of said inspection item in response to a second abnormality signal.
Claim 11
Independent Claim
193 words
A system for indicating an abnormal condition of an automobile, comprising: detector means for detecting the condition of an inspection item relating to the driving of the automobile and producing a detection signal; sensor for detecting the level of said parameter for determining the generation of a cautioning voice and producing a signal corresponding to the level of said parameter; operational processing means for producing a first abnormality signal when deciding that said detection signal from said detector means has reached a first abnormal level and that said signal from said sensor has reached a predetermined level for issuing a caution signal, said operational processing means producing a second abnormality signal regardless of the condition of the signal of said sensor when deciding that said detection signal from said detector means has reached a second abnormality level; and voice generator means for generating a voice cautioning the driver of the abnormal condition of said inspection item in response to a first abnormality signal from said operational processing means, said voice generator means generating a voice warning the driver of the abnormal condition of said inspection item in response to a second abnormality signal.
