Patent ID: 10479361

Abstract:
An apparatus and method of controlling a braking force of a vehicle can improve fuel efficiency by increasing the rate of regenerative braking in the vehicle. The method includes: determining a required deceleration based on a running state of other vehicle ahead; determining a maximum value of a maximum creep torque of a motor and a maximum creep torque of a battery as an amount of available creep torque; determining a smaller value of a required deceleration and the amount of available creep torque as the creep torque; determining a motor torque based on the creep torque; performing regenerative braking by controlling the motor so as to follow the determined motor torque; calculating a deceleration torque based on the creep torque and calculating an amount of hydraulic braking based on the deceleration torque; and performing hydraulic braking according to the calculated hydraulic braking amount.
