1. A method for braking a vehicle, the method comprising:
braking, by a controller, a driving wheel of the vehicle by performing regenerative braking or auxiliary braking;
comparing, by the controller, a required braking force with braking force of the driving wheel; and
additionally braking, by the controller, a non-driving wheel of the vehicle, when the controller concludes that the braking force of the driving wheel is lower than the required braking force,
wherein the controller is configured to perform a first control of braking the non-driving wheel with a first braking force determined from a difference value between the required braking force and the braking force of the driving wheel, when the controller concludes that a braking force reduction value of the driving wheel is lower than a reference value, and
wherein the controller is configured to perform a second control of braking the non-driving wheel with a second braking force in proportion to the braking force of the driving wheels in a predetermined ratio, when the controller concludes that the braking force reduction value of the driving wheel is equal to or greater than the reference value.
