PURPOSE:To acquire an accurate lubricating oil exchange warning, by memorizing the running distance of the operation record and the real running distance, and correcting the oil exchange time after supplying oil depending on the oil supply rate and the real running distance at the oil exchange time. CONSTITUTION:Specific physical quantities varied according to a vehicle operating condition are detected by various kinds of sensors 1, and those physical quantities are added in an arithmetic unit 2 according to a specific operation formula, and the operations are integrated with the passage of time thereafter. When the integrated value exceeds a specific value, a warning signal is output to warn through a warning device 3. In this case, the running distance from the operation record and the real running distance computed in the arithmetic unit 3 are stored in a memory 4. And when the lubricating oil is resupplied, the output time of the warning for oil exchange is corrected by a correcting device 5 depending on the exchange time computed in the arithmetic unit 2 from the real running distance and the supply rate of the lubricating oil. |
