Vehicle behavior control system

A vehicle behavior control apparatus comprising:

• a vehicle body speed detection unit which detects a vehicle velocity of a vehicle
• a steering angle detection unit which detects a steering angle of a steering wheel
• a standard yaw rate calculation unit which calculates, based on the vehicle velocity and the steering angle, a standard yaw rate of the vehicle which has a positive or negative sign in accordance with a turning direction of the vehicle,
• a yaw rate detection unit which detects a yaw rate of the vehicle as a detection value having a positive or negative sign in accordance with a turning direction of the vehicle, and
• a braking force application unit which applies braking force to wheels of the vehicle on an internal side of a turning circle in accordance with a difference between the standard yaw rate and the yaw rate detection value at the time of vehicle turning,
• a slip angle differential value calculation unit which calculates a slip angle differential value of the vehicle body;
• and
• a braking force application prohibition unit which prohibits the application of a braking force by the braking force application unit when:
• the yaw rate detection value is a positive value and the slip angle differential value is a positive judgment threshold or more;
• or
• the yaw rate detection value is a negative value and the slip angle differential value is a negative judgment threshold or less.
