Vehicle behavior control device

A vehicle behavior control device comprising:

• a power source configured to output a torque for driving road wheels of a vehicle;
• a braking device capable of applying different braking forces, respectively, to right and left road wheels of the vehicle;
• a steering wheel configured to be manipulated by a driver;
• a steering angle sensor configured to detect a steering angle of the steering wheel;
• and
• a processor configured to control the power source and the braking device,
• wherein the processor is configured:
• when the steering angle is increasing, to set an additional deceleration to be added to the vehicle, and reduce the output torque of the power source so as to attain the additional deceleration;
• when the steering angle is decreasing, to set a yaw moment oriented in a direction opposite to that of a yaw rate being generated in the vehicle, as a target yaw moment to be applied to the vehicle, and control the braking device to apply the target yaw moment to the vehicle;
• and
• when the steering angle is small, to set the target yaw moment to a value lower than that when the steering angle is not small.
