Abstract
A vehicle behavior control device includes a turning limit state detecting device for detecting a turning limit state of a vehicle and an engine output control device for performing a torque-down control by decreasing an engine output when the turning limit state of the vehicle is detected. The engine output control device includes a longitudinal acceleration detecting device, a lateral acceleration detecting device, a road friction coefficient estimating device, a maximum longitudinal acceleration calculating device for calculating a maximum longitudinal acceleration from the estimated road friction coefficient by the road friction coefficient estimating device and the lateral acceleration detected by the lateral acceleration estimating device, and a margin calculating device for calculating a margin of the longitudinal acceleration of the vehicle as a deviation between the maximum longitudinal acceleration calculated by the maximum longitudinal acceleration calculating device and the longitudinal acceleration detected by the longitudinal acceleration detecting device.
