ABSTRACT:
A degree of sporty driving, or degree of load on tires of a vehicle, is detected based on a usage degree of tire performance. A horizontal force exerted on a tire is calculated and estimated based on longitudinal acceleration and lateral acceleration. Then a ratio, of the horizontal force to a maximum limit gripping force of the tire, is determined to enable detection of the load on a tire at all times.
