PROBLEM TO BE SOLVED: To provide a vehicle behavior control device for reducing a sense of incompatibility to a driver.
SOLUTION: The vehicle behavior control device is provided with a steering angle detection means for detecting or estimating the steering angle of a handle; a vehicle speed detection means for detecting the speed of a vehicle; a control dead zone width setting unit, having a control dead zone in the neighborhood of a steering angle 0 as the output of the steering angle detection means for setting a control dead zone width large at a low vehicle speed side, and for setting the control dead zone width small at a high vehicle speed side, with respect to a steering angle as the output of the steering angle detection means, and for outputting a control dead zone width corresponding to the vehicle speed as the output of the vehicle speed detection means; and a vehicle deceleration control execution determining unit, when the absolute value of the steering angle as the output of the steering angle detection means is larger than the upper limit of the absolute value of the steering angle set with control dead zone width as the output of the control dead zone width setting unit, for generating an output for deceleration control of the vehicle, wherein the deceleration control of the vehicle is executed by the output for deceleration control of the vehicle deceleration control execution determining unit.
