The relationships between various predetermined loading states and the stability factor (Kh) of a vehicle and lateral acceleration (Gy) of the vehicle are stored in a storage device (30A) as reference relationships (i.e., a map). Information regarding the lateral acceleration (Gy) of the vehicle is acquired using a lateral acceleration sensor (40). Estimated values for the stability factor (Kh) of the vehicle are computed on the basis of vehicle driving data when turning. The loading state of the vehicle is estimated on the basis of whether the estimated values for the stability factor that were computed, the vehicle driving data provided for the estimated value computation, and the lateral acceleration of the vehicle of the same time are in an area of any of the reference relationships. |
