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.
