Provided are a driving simulator apparatus and a driver rehabilitation training method using the apparatus, the apparatus including: a display unit for displaying a preset simulation driving screen; a mode selecting unit via which a normal mode, an assist mode, or a resist mode is selected by a user; and a control unit for controlling to apply a driving force in a rotational direction of a steering wheel operated by a user when the assist mode is selected and to apply a reaction in an opposite direction to the rotational direction of the steering wheel operated by the user when the resist mode is selected. Accordingly, a driver with a degraded driving capability due to the aging or brain lesions may have effective driving rehabilitation training. In particular, besides the normal mode, the assist mode and the resist mode are added to conduct target tracking training to thereby improve visual-motor coordination of the user, thereby recovering the driving capability of a patient, which has degraded due to physical and cognitive damages. In addition, by configuring a program according to a state of a patient who needs driving rehabilitation, a recovery state of the patient according to continuous practicing may be estimated by comparing the same with an initial state of the patient. Also, the patient's fun or interests may be aroused so as to allow the patient to concentrate on practicing.
