<p>PROBLEM TO BE SOLVED: To support driving using a result of detecting a tire wear amount.SOLUTION: While a vehicle travelling straight, a travel distance and the number of rotations of a tire are accumulated. Further, when the cumulative travel distance (a straight distance) reaches a given distance, a wear amount is detected from a cumulative value of the number of rotations obtained for each time (the number of cumulative rotations in straight travel). Then, based on the wear amount obtained for each tire, a determination is made for applicability of maintenance necessary for a tire and a category of maintenance, and a drive is presented with the determination result. This makes it possible to release the driver from a burden paid for the maintenance of the tire, allowing an effective use of the information of the wear amount detected for each tire.</p> |
