Summary:PROBLEM TO BE SOLVED: To provide a vehicle and the like to estimate with high precision the amounts of dislocation of individual suspensions by using an existing on-vehicle sensor, utilized for the vehicle behavior control or the like. SOLUTION: The vehicle 1 is adapted to calculate a first attitude factor indicating the attitude of a vehicle coordinate system with respect to a global coordinate system, and a second attitude factor indicating the attitude of an inertial principal-axis coordinate system with respect to the global coordinate system by using a vehicle speed sensor 101, a three-axis acceleration sensor 101 and a yaw rate sensor 103. The first and second attitude factors become determining factors of distribution modes of an inertial force F1 and an external force F2 exerted on the vehicle 1 onto their respective suspension vectors Sm, together with a root vector rm and a suspension vector sm indicating mounting modes of the individual suspensions onto a vehicle body B.
