Vehicle attitude control system and method

It is possible to operate routinely in a decrease of the running stability of the vehicle while respecting the intentions of the driver can be suppressed, and yet the travel control device of a simple configuration in capable of realizing the vehicle motion control vehicle and a control method. Travel control device for controlling the turning attitude of the vehicle, a steering amount detecting means for detecting a steering amount by a driver of the vehicle, vehicle speed detecting means for detecting a traveling speed of the vehicle, the actual turning movement of the vehicle wherein the actual turning state quantity detecting means for detecting status variables, the steering amount and the target turning state quantity calculating means for calculating a state quantity of the target to become turning motion of the vehicle from the traveling speed, and the actual turning state quantity deceleration based on the deviation between the target turning state quantity, the actual turning state quantity calculating the acceleration and deceleration to correct the vertical load of the front wheels and the rear wheels so as to prevent divergence from the target turning state quantity comprising a calculation unit, a longitudinal force control means for increasing or decreasing the longitudinal force with respect to at least one wheel based on the acceleration amount.
