摘要

An automotive abnormality forecasting and warning method and system for issuing a voice and visual alarm when a signal representing the condition of an automotive inspection item exceeds a predetermined value, which comprise steps of calculating the cooling water temperature change rate in variable cycles, determining a calculation cycle corresponding to the detected water temperature and the calculated change rate from a memory storing the cooling water temperature, water-temperature-change rate and calculation cycle in a predetermined relation, judging whether the detected water temperature and the calculated change rate are in a predetermined water overheat region, and issuing a voice alarm on an overheating trend in response to more than a predetermined number of the judging operations.
