Apparatus and method for controlling braking of vehicle

A method for controlling braking of a vehicle, comprising:

• determining, by a first controller, a required deceleration based on a running state of other vehicle ahead;
• determining, by the first controller, 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, by the first controller, a smaller value of a required deceleration and the amount of available creep torque as the creep torque;
• determining, by the first controller, a motor torque based on the creep torque;
• and
• performing, by a second controller, regenerative braking by controlling the motor so as to follow the determined motor torque.

An apparatus for controlling braking of a vehicle, comprising:

• a sensor to determine a required deceleration based on a running state of other vehicle ahead;
• a first controller to determine 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, to determine a smaller value of a required deceleration and the amount of available creep torque as the creep torque, and to determine a motor based on the creep torque;
• a second controller to perform regenerative braking by controlling the motor so as to follow the determined motor torque;
• a third controller to calculate a deceleration torque based on the creep torque, to calculate an amount of hydraulic braking based on the deceleration torque, and to perform hydraulic braking according to the calculated hydraulic braking amount.
