Abstract
A warning system for vehicles monitors malfunctions in various items of a vehicle which are to be detected, such as, the failure of the tail lamps, headlamps, etc., whereby when a malfunction is detected in any one of the items, a visual indication corresponding to the malfunction of the item is given inside the vehicle compartment and then the indicated malfunction is indicated by voice inside the vehicle compartment when it is determined that a predetermined time has expired from the time of beginning the visual indication. The magnitude of the voice is controlled by the ambient sound level detected in the vehicle compartment.

2. A warning system for vehicles comprising:
-
a plurality of sensors each thereof being adapted to monitor the condition of one of a plurality of items of a vehicle which are to be monitored; control means responsive to fault signals from said plurality of sensors whereby, when it is determined that the condition of at least one of said items to be detected is faulty, a display command signal corresponding to said faulty item is generated and then a voice command signal corresponding to said faulty item is generated when it is determined that a predetermined time has expired from the time of generation of said display command singal; display means responsive to said display command signal from said control means to display said faulty item inside a vehicle compartment; and voice generating means responsive to said voice command signal from said control means to generate a voice indicative of said faulty item within said vehicle compartment.

3. A warning system for vehicles comprising:
-
a plurality of sensors each thereof being adapted to monitor the condition of one of a plurality of items of a vehicle which are be monitored; a microcomputer responsive to fault signals from said plurality of sensors to check for any malfunctions in said items to be monitored by programmed computing operations whereby, when the condition of at least one of said items to be detected is faulty, a display command signal corresponding to said faulty item is generated and then a voice command signal corresponding to said faulty item is generated when it is determined that a predetermined time has expired from the time of generation of said display command singal; display means responsive to said display command signal from a microcomputer to display said faulty item; and voice generating means responsive to said voice command signal from said microcomputer to generate a voice indicative of said faulty item. - View Dependent Claims (4, 5, 6)

7. A warning sytem for vehicle comprising:
-
a plurality of sensors each thereof being adapted to detect respective faulty conditions of a vehicle which are preselected to be detected; display means for displaying in a vehicle compartment at least one of said faulty conditions detected by said sensors; timer means for measuring the lapse of time after the initiation of the faulty condition display by said display means; voice generator means for generating in the vehicle compartment a voiced warning indicative of the faulty condition being displayed by said display means when the lapse of time measured by said timer means exceeds a predetermined time; a microphone for detecting an ambient sound level in the vehicle compartment; and control means for controlling the magnitude of said voiced warning of said voice generator means in accordance with said ambient sound level detected by said microphone.
