Vehicle behavior control device

A vehicle behavior control device comprising:

• a turning limit state detecting means for detecting a turning limit state of a vehicle;
• and
• an engine output control means 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 means including a longitudinal acceleration detecting means for detecting a longitudinal acceleration in a substantially longitudinal direction of the vehicle, a lateral acceleration detecting means for detecting a lateral acceleration in a substantially lateral direction of the vehicle, a road friction coefficient estimating means for estimating a road friction coefficient, a maximum longitudinal acceleration calculating means for calculating a maximum longitudinal acceleration as a maximum value of the longitudinal acceleration being generated from the estimated road friction coefficient by the road friction coefficient estimating means and the lateral acceleration detected by the lateral acceleration estimating means, and a margin calculating means 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 means and the longitudinal acceleration detected by the longitudinal acceleration detecting means;
• wherein a gradient of an engine output increase is controlled in response to the margin of the longitudinal acceleration of the vehicle calculated by the margin calculating means at a recovery stage of the engine output for reducing the engine output decrease amount during the torque-down control.
