Abstract
In a behavior control device of a vehicle adapted to control the brake system according to a calculation based upon vehicle speed detected by a vehicle speed sensor, steering angle detected by a steering angle sensor, and yaw rate detected by a yaw rate sensor such that, when a deviation of the yaw rate detected by the yaw rate sensor relative to a standard yaw rate estimated from the vehicle speed and the steering angle increases beyond a threshold value, at least one of the wheels is braked by the brake system so as to generate a yaw moment in the vehicle body for decreasing the deviation of the yaw rate, the threshold value is temporarily increased until the yaw rate sensor is warmed up.
