Abstract

Abstract A centralized warning system for vehicles is provided wherein ''''1'''' and ''''0'''' signals are received from a plurality of sensors mounted at various parts of a vehicle where checking is required, whereby according to preliminary classified conditions of danger for the driving of the vehicle, such as ''''NORMAL'''' indicating that there is no abnormality in any part, ''''WARNING'''' indicating that there is no impending danger for the driving of the vehicle but caution is required, and ''''DANGER'''' indicating that there is a considerable danger for the driving of the vehicle, it is determined which of the three conditions of danger, for example, ''''NORMAL,'''' ''''WARNING'''' and ''''DANGER'''' is identified by the ''''1'''' and ''''0'''' signals generated by the sensors and a pertinent one of warning devices such as warning lamps corresponding respectively to the three conditions of ''''NORMAL,'''' ''''WARNING'''' and ''''DANGER'''' is lit accordingly to thereby indicate the condition of danger presented by the defective part. Furthermore, when two or more abnormality signals are simultaneously generated by said plurality of sensors, the locations of defective parts are displayed and brought to the driver''s notice in the form of letters, figures or pictures by an indicating device such as a lettered drum according to the predetermined orders of priority allocated to such abnormality signals in order of condition of danger against the driving of the vehicle. In addition, the warning device and the indicating device are collectively installed in the most conspicuous place for attracting the driver''s attention so that the driver can observe by virtue of these collectively installed warning device and the indicating device whether the checking spots are in normal condition or involve any abnormal condition and, if there is any abnormal condition, the driver can also know the condition of danger and the location of the part involving the abnormality and at the same time there is no danger of the driver failing to concentrate his whole mind upon the driving of the vehicle thus greatly contributing toward the safe driving of the vehicle.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 219 words
A centralized warning system for vehicles comprising: first means including a plurality of sensors for generating signals representative of the absence or presence of an abnormality each at a selected location in the vehicle to be monitored, second means having an input responsive to each of said sensor signals and a plurality of logic elements connected in circuit with each of the input thereof for categorizing the abnormality when happened, of the selected location into at least two classes predetermined according to a selected categorization of the degree of danger of driving the vehicle under such an abnormal condition, one class being of higher degree of danger and the other of lower degree of danger, and generating output signals indicative of each selected location where an abnormality exists and the categorized class to which the abnormality belongs, warning means responsive to said output signals and including signal means for signalling the driver that an abnormality exists at at least one of said selected locations and further including display means for visually indicating abnormal locations, and priority determining means operative on said warning means to cause same to indicate the abnormality belonging to the higher degree of danger when both the higher and lower degree of abnormality indicating output signals are received by the warning means at the same time.
Claim 2
Dependent Claim 219 words
A centralized warning system for vehicles comprising: first means including a plurality of sensors for generating signals representative of the absence or presence of an abnormality each at a selected location in the vehicle to be monitored, second means having an input responsive to each of said sensor signals and a plurality of logic elements connected in circuit with each of the input thereof for categorizing the abnormality when happened, of the selected location into at least two classes predetermined according to a selected categorization of the degree of danger of driving the vehicle under such an abnormal condition, one class being of higher degree of danger and the other of lower degree of danger, and generating output signals indicative of each selected location where an abnormality exists and the categorized class to which the abnormality belongs, warning means responsive to said output signals and including signal means for signalling the driver that an abnormality exists at at least one of said selected locations and further including display means for visually indicating abnormal locations, and priority determining means operative on said warning means to cause same to indicate the abnormality belonging to the higher degree of danger when both the higher and lower degree of abnormality indicating output signals are received by the warning means at the same time.
Claim 3
Dependent Claim 60 words
A centralized warning system for vehicle according to claim 1, wherein said display means comprises means for providing a distinct visual display indication of the abnormality belonging to the higher degree of danger in response to said priority determining means when both of the abnormalities belonging to the higher and lower degree of danger take place at the same time.
Claim 4
Dependent Claim 25 words
A centralized warning system for vehicles according to claim 2 wherein said display means has means for displaying only a single abnormality at a time.
Claim 5
Dependent Claim 49 words
A centralized warning system for vehicles according to claim 1 wherein said signal means comprises, lamp emitting means for providing at least three different modes, the first indicating a totally normal condition, the second indicating a lower degree of danger and the third indicating a higher degree of danger.
Claim 6
Dependent Claim 56 words
A centralized warning system for vehicles according to claim 4 wherein said priority determining means comprises lamp mode selecting means for selecting only the third mode of said lamp emitting means indicating a higher degree of danger when both of the abnormalities belonging to the higher and lower degree dangers take place at the same time.
Claim 7
Dependent Claim 60 words
A centralized warning system for vehicles according to claim 5 wherein said display means comprises, means for providing a distinct visual display indication of the abnormality belonging to the higher degree of danger in response to said priority determining means when both of the abnormalities belonging to the higher and lower degree of danger take place at the same time.
Claim 8
Dependent Claim 25 words
A centralized warning system for vehicles according to claim 6 wherein said display means has means for displaying only a single abnormality at a time.
Claim 9
Dependent Claim 60 words
A centralized warning system for vehicles according to claim 4, wherein said display means comprises, means for providing a distinct visual display indication of the abnormality belonging to the higher degree of danger in response to said priority determining means when both of the abnormalities belonging to the higher and lower degree of danger take place at the same time.
Claim 10
Dependent Claim 25 words
A centralized warning system for vehicles according to claim 8 wherein said display means has means for displaying only a single abnormality at a time.
