Abstract
A vehicle control system estimates the vibration states of tires by using a vehicle vibration model that is separated into a vehicle body vibration model, a chassis vibration model, and a tire vibration model with high precision. The tire vibration model in the vehicle vibration model is formed of a rear wheel tire vibration model, a front wheel tire vibration model, and a virtual coupling element vibration model that virtually couples the rear wheel tire vibration model and the front wheel tire vibration model. Influence of the vibration state that is conducted between the front wheel tires and the rear wheel tires is considered while the tire vibration model and the chassis vibration model are separated from each other, thereby making it possible to estimate the vibrations that occur in the front wheel tires and the rear wheel tires.
