Brake force distribution device for vehicle and method thereof

A brake force distribution device for a vehicle, comprising:

• a turning state detection part comprising a sensor and disposed to detect whether the vehicle is in a turning state based on a driving state of the vehicle;
• a vehicle speed detection part comprising another sensor and disposed to detect whether a vehicle speed is equal to or less than a prescribed threshold;
• and
• a processor configured to:
• calculate a first yaw moment based on the driving state, the vehicle speed and a first wheelbase of the vehicle, wherein the first wheelbase is an imaginary wheelbase of the vehicle;
• calculate a second yaw moment based on the driving state and the vehicle speed as well as based on a second wheelbase which is an inherent value of the vehicle;
• calculate a target moment based on a difference between the first yaw moment and the second yaw moment;
• and
• control brake force distribution of wheels of the vehicle based on the target moment;
• wherein the processor controls the brake force distribution of the wheels based on the target moment when the vehicle turns and the vehicle speed is equal to or less than the prescribed threshold.
