APPARATUS AND METHOD FOR ESTIMATING STEERING ANGLE BASED ON DIFFERENTIAL BRAKING, AND COMPUTER-READABLE STORAGE MEDIUM STORING PROGRAM FOR PERFORMING THE METHOD

An apparatus and method, and a non-transitory computer-readable storage medium storing a program for performing the method estimates a steering angle based on differential braking. The apparatus may include a memory configured to store an estimation model having at least one coefficient and defining the relationship between a differential braking force of a vehicle and a steering angle of free-rolling front wheels of the vehicle; and a processor configured to input test data comprising a plurality of differential braking forces and steering angles generated when the plurality of differential braking forces are applied to the estimation model, respectively, and determine the at least one coefficient of the estimation model.
